Faq: Ios 14 Checkra1N Jailbreak

The checkra1n jailbreak recently picked up support for iOS 14 on devices equipped with Apple’s A8-A9X processors, but as many noticed on the night this happened, the checkra1n team also elucidated on how it would take more time to add support for A10 and A10X devices and that they weren’t even sure if they would be able to add support for A11-equipped devices like the iPhone 8, 8 Plus, and X.

Given the rather unexpected and uncertain circumstances, we’re sure there are a lot of questions about the checkra1n jailbreak and when or if it will receive updates to support newer devices. With that in mind, we wanted to take a moment to deliver an FAQ-style post that would discuss many of the most common questions and the best answers for those questions that we have at the time of this writing.

iOS 14 checkra1n jailbreak FAQ

Here’s a brief overview of everything you should know about the current circumstances surrounding checkra1n’s iOS & iPadOS 14 compatibility:

What devices does checkra1n support on iOS 14?

At the time of this writing, checkra1n v0.11.0 supports A8, A8X, A9, and A9X devices running Apple’s iOS & iPadOS 14 operating systems. Update: checkra1n can now jailbreak all A8, A8X, A9, A9X, A10, A10X, and A11 devices running iOS or iPadOS 14, however there’s a catch for A11 devices, as you won’t be able to use a passcode on these devices if jailbroken.

What devices does checkra1n not support on iOS 14?

At this time of this writing, checkra1n v0.11.0 does not support A10-A11 devices running Apple’s iOS & iPadOS 14 operating systems. Update: checkra1n now supports all A8-A11 devices running iOS or iPadOS 14.

Will the checkra1n team ever add support for the above devices?

The checkra1n team said they to add support for A10 and A10X devices “in coming weeks,” but there is no concrete ETA for such support. Update: support for these devices is now available. The checkra1n team is needing to jump through extra hoops to make the jailbreak work on A10 and newer devices because Apple implemented new a security mitigation to SEPOS that makes it substantially more difficult to achieve a jailbreak these handsets. A known security vulnerability called blackbird, however, will allow the checkra1n team to work around this on devices equipped with A10 and A10X processors.

As for A11 devices like the iPhone 8, 8 Plus, and X, these devices utilize newer hardware with even tighter security. The checkra1n team isn’t entirely sure if they can get the jailbreak up and running on these devices anytime soon, but they won’t be giving up. In fact, they’ll be working around the clock to find ways around the upgraded security in the near future in an attempt to reestablish support for these devices. Unfortunately, A11 devices aren’t affected by the aforementioned blackbird security vulnerability, which leaves the hackers forced to start back at square one.

How do I jailbreak with checkra1n? I accidentally updated to iOS 14, what do I do now?

Assuming you have an A8-A9X device, you can jailbreak it with checkra1n right now. Unfortunately for everything else, Apple stopped signing the last iteration of iOS 13 earlier this week, which means official methods of downgrading your firmware are no longer viable. We’d recommend saving your SHSH blobs and remaining patient for a novel development.

Isn’t the checkra1n jailbreak supposed to be un-patchable?

The checkm8 bootrom exploit that powers the chreckra1n jailbreak is, in fact, un-patchable, but Apple’s iOS 14 update makes it more difficult to complete the process that checkra1n sets out to achieve on A10-A11 devices by adding security mitigations via SEPOS. More specifically, as the checkra1n team puts it, “if the device was booted from DFU mode and the Secure Enclave receives a request to decrypt user data, it will panic the device.” With that in mind, the checkra1n team will now need to consider burning SEPROM exploit(s) if they are to make checkm8 viable on A11 devices.

In short, the checkm8 bootrom exploit hasn’t been patched (and can’t be), Apple has just made it more difficult to apply it to certain devices. The checkra1n team will need time to develop a workaround.

How much longer before the iPhone 8, 8 Plus, and X can be jailbroken on iOS 14 with checkra1n?

This is a good question, and unfortunately, no one knows the answer. It could take a while to develop a workaround for Apple’s latest security mitigation, and there’s no telling how long that might take. Fortunately, we have very talented hackers at the forefront of the checkra1n team, so let’s keep our fingers crossed.

How does all of this impact the jailbreak community?

As long as you have an A8-A9X device at your disposal, the latest security mitigation won’t impact you at all and you can continue jailbreaking iOS 14 with checkra1n just as you did on iOS 13.

If you have an A10 or A10X device, you’ll simply need to wait a little longer (a few more weeks) to be able to jailbreak on iOS 14 as you were able to on iOS 13.

If you have an A11 device, then you should keep it on iOS 13 instead of upgrading for now. This ensures that you can jailbreak with checkra1n in the meantime until a workaround can be found for Apple’s new security mitigation. Alternatively, you can use another jailbreak like Odyssey or unc0ver.

What does the future of checkra1n hold?

From what we can gather, the checkra1n team has no intention of raising the white flag merely because Apple made things a little bit more difficult with iOS 14. Checkra1n team member Luca Todesco Tweeted just this afternoon that the team will “put in real effort to drop real research and development to keep it alive.”

It doesn’t seem like the checkra1n team will be going anywhere, and this certainly also applies to the jailbreak itself. Just because Apple made it more difficult to jailbreak certain devices running iOS 14 doesn’t mean that checkra1n will become any less relevant to the community or that it will suddenly disappear off the face of the Earth.

Should I ask the checkra1n team for ETAs?

Please don’t pester the checkra1n team with relentless ETA questions. Not only are they likely to be ignored to receive sarcastic responses, but they do nothing productive to help the team. For everyone’s sake, merely follow the checkra1n team and its members on Twitter to receive the latest updates and keep it tuned to iDownloadBlog for the latest news and tutorials.

What about A12 and newer devices on iOS 14?

The checkra1n jailbreak has never supported devices newer than the A11 variety, and it probably never will. This is because the jailbreak is based on a bootrom exploit that only impacts older hardware. Those using A12 and newer devices should wait for another jailbreak tool to receive iOS 14 support.

Although some iOS & iPadOS 14 users have hit rough water with the checkra1n jailbreak, that doesn’t mean that newer devices affected by the checkm8 exploit will be un-jailbreakable on iOS 14 forever. It’s entirely possible that someone from the checkra1n team will find a way around Apple’s latest security mitigation or that another jailbreak team might develop a tool for all devices before then.

In any case, we see regular jailbreak updates and releases throughout the year, and so I don’t expect that the community will be too horribly burned from the circumstances.


Apple may have made iOS and iPadOS 14 a bit more difficult to bust on certain devices, but we remain overtly optimistic about the situation. Our community is in good hands with the talented hackers that develop the jailbreaks we use every day, and there’s no shortage of exploits making their way to the pubic that may help push the community forward.

Faq: Ftc’s Lawsuit Against Intel

The Federal Trade Commission filed an antitrust-related lawsuit against Intel Wednesday, accusing the chip maker of deliberately attempting hurt its competition and ultimately consumers. The landmark lawsuit alleges that Intel has deprived customers of choice by trying to slow down innovation among its rivals, and by keeping computer makers hooked with lucrative incentives for doing little business elsewhere.

Why is the FTC going after Intel now?

Intel’s allegedly anticompetitive practices have been in the news quite a bit lately, with “smoking gun” e-mails revealed in Europe’s antitrust lawsuit against Intel, the chip-maker’s settlement with underdog AMD, and New York Attorney General Andrew Cuomo’s antitrust lawsuit against Intel. Dan Olds, principal analyst for the Gabriel Consulting Group, says that, against this background, it didn’t look good for the FTC to sit on the sidelines, and that the commission will likely seek a fine from Intel. Jim McGregor, In-Stat’s chief technology strategist, also called the lawsuit a publicity move by the government.

Have consumers been paying too much for processors?

Illustration: Harry Campbell

If the FTC’s allegations are true, consumers actually have not been paying too much for their PCs, according to experts. Because Intel has been allegedly attempting to undercut the competition, the price of Intel PCs may have been artificially lowered.

This isn’t about pricing for consumers, says Leslie Fiering, Gartner’s research vice president. At issue is whether it’s illegal to provide discounts and other incentives in exchange for a certain amount of business. So you could argue that Intel’s practices saved end-user customers money by charging manufacturers less. Those savings were theoretically passed on to consumers.

From a macro perspective, you could argue that in the long run, Intel’s alleged anticompetitive behavior could stifle the competition (AMD) and thereby allow Intel to own the PC semiconductor market and start charging much higher prices. But that scenario has not played out yet, say experts.

So what have consumers lost, superior products?

One of those possibly hurt is nVidia with its Ion graphics mobile chip. We won’t know for sure until details emerge, but nVidia may possibly have been locked out of netbooks whose manufacturers stuck millions of mininotebooks with the Atom’s integrated graphics, which can’t deliver high-quality video and is not adequate for graphics-heavy games.

Do consumers stand to gain better products as a result of the lawsuit?

nVidia isn’t so pessimistic. It applauds the FTC’s lawsuit, saying that it’s necessary to prevent Intel from blocking competition in the emerging GPU marketplace.

How will this case impact AMD?

Graphic: Diego AguirreMcGregor said it’s too late for the feds to give AMD a boost, as the company recently settled antitrust and intellectual property lawsuits with Intel. Gartner analyst Fiering also noted that Intel’s success comes partly from being a manufacturing powerhouse. AMD is divesting from chip manufacturing, and the settlement allows AMD to use any contract chip maker. In theory, this lets the company focus on innovation and product development, but that has nothing to do with the FTC’s lawsuit.

PCWorld’s resident chip expert, Jason Cross, says never say never when it comes to AMD. The company has very good engineers, a leadership position in graphics technology, and a huge cash infusion from the recent Intel/AMD suit settlement. Plus, AMD is quickly divesting their chip manufacturing off to GlobalFoundries, which should help prevent AMD from bleeding red ink.

How long will this case take to play out? In the end, what do consumers stand to gain?

Olds and McGregor both think the suit has very little in it for consumers. Even if Intel had to make concessions on volume discounts to computer makers, chip prices, McGregor says, would still fall due to consumer expectations and competition from AMD.

Will we see more AMD systems?

McGregor says that’s already happened over the last couple of years, partly because of increased scrutiny of Intel from other nations and partly because AMD has offered good prices on CPU and GPU combinations. And it’s unlikely that consumers will be compensated directly as a result of the FTC’s lawsuit, since fines would probably be placed in a general government fund.

The real winners, Olds says, are the lawyers, who could work on these cases for the rest of their legal careers.

Add Coloured Tabs To The Firefox Interface

Sometimes you just have too many tabs to handle. The modern Web is reliant on tab-based browsing, and it’s easy to fall into the habit of opening numerous tabs at once and ignoring them.

Developers have come up with their own solutions for this oft-repeated habit, such as pinning or grouping tabs (both of which can already be done in Firefox). Changing the color of tabs can have the same effect, and you may find it more visually pleasing than the above interface for tab groups.


This particular tip applies exclusively to Mozilla Firefox and its related browsers, such as those on other release channels or even other browser variants based on Firefox.

Providing your browser relates to Firefox in some way, follow the simple steps below to download and configure the extension.

2. Firefox will ask you whether or not you want to allow the installation. Give permission and accept the familiar extension installation prompt.

3. Restart Firefox and you’ll see an immediate change with the browser, with the appearance of tabs totally changed.


Once you have the Coloured Tabs extension installed, you can begin to tweak things to suit your own preferences. Begin by bringing up the Addons tab (Ctrl + Shift + A), then select “Options” in the extension. There is a surprisingly large amount of control, given how simple coloured tabs sound in concept.

One of the most interesting options under the “General” heading is highlighted in the above pictures, “Generate Colors by Domain Hostname”. The example above has three tabs for YouTube and two for Make Tech Easier, and they’re colour-coded. You can augment domain colour matching by setting specific colours, as we did with Facebook.

All you need is the hex code for the colour (#46629E, in Facebook’s case). The Vivaldi web browser, which we covered a few months ago, had a similar approach to reflecting palette choices.

With ColorfulTabs’ intention being to visually differentiate tabs, they no longer need to display as much information, so you can compress their size. Mini Mode, therefore, leaves the browser looking like this:

Mini Mode is different than Firefox’s default “Pin Tabs” option, as they are not forced to the first positions in the browser and can display some text. The visual difference is made clearer when they are shown side by side.


ColoredTabs is an interesting extension, for its purpose is divisive. Everyone’s Web browsing habits are different, whether they return to a small number of sites or find themselves traversing a large number of unfamiliar pages. As a result, not everyone would wish for easily-identified tabs, but the other features sweeten the deal and could be enough of a reason to install ColorfulTabs.

Lulz Boat Hacks Sony’s Harbor: Faq

The hacker group LulzSec made good on its recent promise to embarrass Sony by compromising the personal information of 1 million users of chúng tôi The latest Sony hack is another black eye for a company that only recently recovered from the hack against Sony Computer Entertainment’s PlayStation Network and Qriocity music service in April.

Here’s a breakdown of LulzSec’s latest hack, which the group is calling Sownage (Sony + Ownage).

How much user data was exposed?

LulzSec says its hack exposed user data for 1 million users; however, the hacker group did not have the computer resources to download all of the exposed material. Based on a summary of the exposed user data on LulzSec’s website, the group included the personal information for more than 51,000 users related to chúng tôi and another 600 users from Sony BMG Netherlands.

What kind of data was stolen?

LulzSec says it was able to expose passwords, e-mail addresses, home addresses, birthdates, and all Sony opt-in data associated with users’ accounts. In some cases, the exposed personal information included home telephone numbers. The Associated Press on Thursday contacted several users by telephone based on information included in LulzSec’s sample. The AP confirmed that at least some of the exposed information was genuine.

Where is this data now?

What should I do if I was hacked?

How was this hack done?

An SQL injection is when a hacker types code requesting data into a Web form instead of the data the site expects, such as a user name or password. If proper precautions are not taken, the code is able to execute and allow hackers to download the database information they requested.

Was the exposed data encrypted?

Who is LulzSec?

LulzSec (Lulz Security) is a hacker group (or possibly just one person) responsible for a number of recent intrusions into corporate servers. The group broke into a Sony site based in Japan, chúng tôi and the recent PBS hack that included posting a fake news item to chúng tôi proclaiming rapper Tupac Shakur was still alive.

As its name suggests, LulzSec claims to be interested in mocking and embarrassing companies by exposing security flaws rather than stealing data for criminal purposes. But that doesn’t mean others won’t capitalize on security flaws exposed by the online pranksters.

It sure looks that way with the recent Gmail hack that Google blames on China, the LulzSec break-ins, and a rash of other intrusions such as the RSA SecurID breach and the Sony PSN hack. But keep in mind that many of these intrusions are the result of companies and users failing to follow basic security measures.

With hackers becoming more emboldened to attack corporate sites, corporations need to do a better job of safeguarding user data. A good start would be to watch out for basic SQL injection techniques, encrypt databases filled with personal information, and provide an HTTPS connection for their users whenever possible. These three basic things would go a long way to thwarting the shenanigans of groups like LulzSec. You can never be 100 percent immune from intrusions, but that’s no excuse for failing to follow even the most basic security precautions.

Complete Guide To Payment Methods At Crypto Casinos

Online Bitcoin casinos are very different from your standard online casino, as they give you the chance to play casino games without using credit and debit cards or any bank transfer for your transactions. You don’t need a bank account to register on a Bitcoin casino.

Bitcoin Casinos Compared to Online Casinos

In standard online casinos, all of the transactions you make while you play online casino games are processed by some strict bank regulations, so there is a lengthy procedure that many online casinos have in place to register a casino account.

Understandably, players would like to avoid such processes at their favorite online gambling sites. Ideally, they would like to choose their preferred payment method and then get on with playing on the site.

Bitcoin casinos eliminate this process, and while creating your casino account, you will not be required to enter information regarding your credit or debit card or leave any sensitive information on the site.

Sometimes, the site will ask for an ID card or some address details just for added security. However, overall, no Bitcoin casino will ask you to complete any long registration forms. When it comes to payment methods, the difference between them and the online

casino payment options

is that there is no need for a third party or any authorization for the whole process.

How Does the Registration Process Work at Bitcoin Casinos?

When the player arrives on the crypto casino site, an immediate registration will occur, and an automatic username will be created for them. Most of the crypto casinos will only need a username and nothing else.

You will need to create a unique password for security purposes, and you can also leave your email address, but this is up to you. That is the big difference between crypto and online casinos; you must leave your email address and debit card details upon registration.

Additionally, when it comes to online payments, all bitcoin deposits and bitcoin transactions, in general, are stored on the


publicly, adding to the security of those transactions.

Cryptocurrencies Accepted at Crypto Casinos

The world of cryptocurrencies changes all the time, so you need to be on pace with what is happening at the moment, especially if you gamble using those and on crypto casinos. Let’s have a look at what are the best cryptocurrencies accepted at any crypto casino.



is the leading digital currency globally, and it is accepted and known by most of the world’s population. Bitcoin was created back in 2008, and it is the first digital currency to be introduced in the world.

Satoshi Nakamoto is the creator, and he described it as the first peer-to-peer payment system. The online casino industry has already accepted it as one of the best payment methods, and players can play their favorite casino games. Fast transactions and low transaction fees make Bitcoin arguably the best payment method that can be used.

The bottom line is that every crypto casino will offer Bitcoin as a payment method, and it comes as no surprise, given its popularity and acceptance. Bitcoin gambling is prevalent nowadays, so almost every casino will accept bitcoin payments.


Ether is described as the native token to Ethereum, and it is the second-largest cryptocurrency, just behind Bitcoin. The main difference with Bitcoin is that it was not created as a crypto platform but as a blockchain-based computing platform with the characteristics of a computing platform.

Ether has gained massive popularity, and it is used in most online casinos for making gambling transactions. Of course, it offers instant deposits while playing the most popular games so that the overall gambling experience will be top-class.


Tether is a stable coin, and its value can be tied to fiat currencies. If you are new in the crypto world, stable coins will remain stable even if there are massive changes and swings in the crypto market. That stability is ensured as the value of stable coins is attached to any other fiat currency.

So, the stability of Tether makes it a very popular payment method that online casinos offer. The most popular casino games and online slots can be played with Tether. You are sure to get instant deposits and withdrawals, so make no mistake – this is one of the best and most stable available payment methods at cryptocurrency casinos.


Litecoin is among the top digital currencies globally, and it is seen as an excellent competitor to Bitcoin. Charlie Lee created Litecoin, and it is very similar to Bitcoin, but there are some important differences.

Litecoin has much faster online transactions than Bitcoin, and these transactions can be processed in under 3 minutes, while with Bitcoin, it can take up to 10 minutes. So, it is no surprise that cryptocurrency casinos insist on having Litecoin among the payment options.

Bitcoin Cash Monero

This is a relatively new cryptocurrency, as it was released in 2014. It represents an open-source crypto platform that guarantees privacy and security among the players using it as their preferred virtual currency for making cryptocurrency payments when they play slots at crypto casinos. Anonymous transactions are the highlight of Monero.

Pros and Cons of Using Cryptocurrencies as Payment Methods


Bigger security – We hear stories every day of big companies being hacked and important data being stolen, so the online gaming industry is not immune to that. Players and casinos can be the subject of such attacks, and it is not a pleasant experience for anyone. However, this will not be an issue when you use a cryptocurrency casino, as there is no need to leave sensitive personal information or card details. You will use a crypto wallet so that the security will be much higher.

Faster withdrawal times – Every player wants to have instant access to their winnings, and that is one aspect that will make a seamless online gambling experience. You will have instant access to all your winnings when using cryptocurrencies, so it is a big plus to have them as one of your withdrawal methods.

Unique games – certain games can be played with cryptocurrencies only, which are new and attractive. You can make some handsome winnings while playing these games.
