How To Root Xiaomi Redmi S2

Xiaomi new budget-level handset, the Redmi S2, was released only last month in the global market while it was already being sold in India as the Redmi Y2. The device is garnering decent success already despite the competition from Xiaomi’s own budget king set of devices in Redmi 5, but if you own the Redmi S2, here’s some good news.

You can now root the Redmi S2 easily. The TWRP recovery for the Xiaomi Redmi S2 is available for download and flashing.

We have provided a guide below to download and install the TWRP on Redmi S2, and then use that to root your device. Here’s how it goes.

Xiaomi Redmi S2 TWRP Recovery

The TWRP recovery for Redmi S2 is available for download and has been provided in the root guide itself below. To install TWRP, just install the root guide given below — as root access is gained only via TWRP recovery, it’s required to be installed first.

If you do not wish to root the device but install only TWRP on your Redmi S2, then be sure to install the DM Verity disabler zip file in TWRP in place of Magisk root package.

Xiaomi Redmi S2 Root

Make sure that you’ve unlocked the bootloader for the Redmi S2 before proceeding.

Download the required files:

TWRP IMG file: redmi-s2-twrp-3.2.1-0-ysl.img

Root file (Magisk 16.4): Magisk

DM verity disabler:

Connect your Redmi S2 to the PC using the USB cable it came with.

Rename the TWRP file (.IMG) on the PC to  chúng tôi  so that it becomes a little easy to type the command to install it later on this guide.

Transfer all the downloaded file (TWRP, Magisk, and DM verity disabler) to your device. Do keep a copy of TWRP IMG file on your PC too. Keep the Redmi S2 connected to PC.

Make sure you have enabled USB Debugging on your Redmi S2, as explained in the bootloader unlock post above (step 1). You may need to re-do it after unlocking the bootloader.

Boot your Redmi S2 into bootloader/fastboot mode. For this run this command: adb reboot bootloader

Install TWRP recovery temporarily and boot it for once by running the command below. To run a command, simply type this in the command window and then hit the enter key. fastboot boot twrp-redmi-s2.img

Reboot into recovery mode. For this, use volume buttons to bring up ‘Recovery mode’ option, and then press the power button to select it and boot into recovery mode and access TWRP.

Enter the password or PIN you are using to let system decrypt in recovery mode and get to TWRP recovery. (It won’t ask if you are not using any PIN or password on the device.)

You will see TWRP recovery now. When asked to ‘Keep System Read only?’, tap on the ‘Keep Read Only’ button to not allow for system modifications.

This recovery is in Chinese. If you wish to, you may change the language to English.

Check out the TWRP recovery. Confirm everything is working alright as you need/want. If you like it, install the TWRP permanently. For this, on the home screen of TWRP, tap on Install button, then Images… button, and then select the chúng tôi file. Confirm the action on next screen by swiping at the bottom of the screen to install it.

In case you don’t want to root (?) the device, be sure to install the DM verity disabler file now (in place of Magisk file) to get the Redmi S2 to boot normally (prevent from bootlooping).

Once it’s done, tap on Reboot System button to restart the device. If and when it asks for ‘Install TWRP App?’, tap on ‘Do Not Install‘ button as you don’t need the TWRP app.

That’s all.

Do let us know if you have any queries regarding root access and TWRP recovery for the Xiaomi Redmi S2 handsets.

Root Galaxy S2 Running On Xwlpg Android 4.0 Firmware

What’s the one thing most people do after flashing or updating to a new firmware on their devices? That would be rooting the particular firmware. And what follows every new firmware release for Samsung’s Galaxy line of devices? It’s the CF-Root kernel for the firmware by XDA Elite Recognized Developer Chainfire, that lets you root your phone, and also install ClockworkMod recovery on it (so you can flash custom ROMs and mods).

If you’ve updated your Galaxy S2 to the XWLPG Ice Cream Sandwich Android 4.0 firmware and are looking to root it, you can do so by flashing the CF-Root kernel for XWLPG by following the guide below, which will also install ClockworkMod recovery on the phone.

Read on to find out how to root XWLPG firmware on the Galaxy S2 i9100.


This hack and the guide below are compatible only and only with Galaxy S2, model number I9100. It’s not compatible with the I9100G or any other device. Check your device’s model number in: Settings » About phone.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Root XWLPG Firmware on Galaxy S2 i9100

Make sure you are on the XWLPG Ice Cream Sandwich Android 4.0 firmware available → here.


DO NOT extract the .tar file (this might show up as a zip file as well, but do not extract it). You need to flash the .tar file using Odin to gain root access and install ClockworkMod Recovery (CWM) alongside. (If you’re getting a zImage file, it means you’ve extracted the .tar file too! — and that’s not a right thing to do.)

Extract the contents of the Odin file to a folder.

Disconnect your phone if it’s connected to PC, then switch it off.

Now, put the Galaxy S2 in Download Mode — press and hold these keys together: Volume Down + Home + Power. A Warning! screen will come up; press Volume Up key to continue to enter Download Mode.

Important! Do not make any other changes in Odin except selecting the required files as given in step 10. Leave all other options as they are.

If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed (check step 1). Also, uninstall Kies from the Control Panel as well (this will leave the drivers on the computer but remove Kies which can interfere with the procedure).

Now, hit the START button to start flashing CF-Root kernel. When the flashing is complete, your phone will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin. What to do if Odin gets stuck: If ODIN gets stuck and doesn’t seem to be doing anything, or you get a FAIL message (with red background) in ODIN, disconnect the phone from the PC, close ODIN, remove battery, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 9.

If you run into any roadblocks while flashing the kernel, let us know and we’ll help you out.

Your phone is now rooted and CWM recovery has been installed on it, with CF-Root kernel. Using all those favourite root-enabled apps of yours is now possible. Enjoy!

Can I Root My Phone, And More On Rooting.

However, a question which every user who desires to root his device must ask is ‘Is my device rootable?’. The answer to this question for any device depends upon the combination of the OS, manufacturer and the device itself.

Strictly speaking, when we talk about a platform as open as the Android OS, it is almost impossible for a manufacturer to make an ‘un-rootable’ device. Attempts have been made by manufacturers of some devices, such as in the case of the Motorola Droid X, where subsequent updates by the manufacturer have ended up unrooting the device.Nonetheless, it’s almost always a matter of developers finding a new security exploit to enable root-access again.

New devices are seldom ‘un-rootable’ when launched. Over a period of time, developers make root exploits available for these devices. Those devices which are on Operating Systems other than the Android OS may have limits to how much elevated access can be provided to the user.

There is no uniform method to find out if a device can be rooted or not. Apps exist which will allow users to check if their device is rooted or not, such as the Simple Root Checker, but finding out if an exploit has been discovered for your device isn’t as easy. The following three broad procedures may allow the user to find out if there exists a process which will allow him to root his device.

Google it!

As always, Google can save the day. It’s as easy as googling the model number of your device with a ‘How to root’ string attached, which will allow you to find a root exploit. For popular devices, and those which have been rooted, there would be numerous results to choose from. For example, as shown in our attached image, we googled ‘How to root N7100’ and established that many search results are found containing the necessary information.

Search on popular Forums

Forums are websites where discussions related to specific topics can be held by users who have interests in these topics. Luckily for smartphone users, numerous such forums exist where information related to their smartphones/tablets etc can be easily found.

It is very easy to learn rooting procedures for your device on these forums, or even to ask questions and start discussions associated with your device. Some other popular smartphone forums similar to XDA are AndroidCentral forums, AndroidForums, iMore forums etc.

Root Tools

There exist some software tools and app, which work on multiple device models and can thus be used to test the root exploit availability and root the device in one go. However, these tools do not merely give you the information regarding the availability of root exploits, they directly root the device, and therefore should be used only when the user is aware of the existing risks and is absolutely positive about rooting his device.

Different manufacturers using different operating systems have varying processes to root their devices. Let us consider the case of the two most popular mobile operating systems and analyse the general methods used to root them.

Android OS

Rooting Android operating systems is fairly popular, implying that exploits can be easily found for popular Android Devices and for many of the obscure ones too. Essentially rooting an Android device includes flashing a custom recovery image.

This modified firmware update will typically include the utilities required to run apps with root access. The rooting procedure would also install a typical supervisor application, such as the SuperSU app, which can be allowed to monitor and provide root access to applications.

Apple iOS

A process used as iOS ‘Jailbreaking’ is used to provide administrator-level access on iOS devices, which is different in principle from rooting in two ways. Firstly, iOS systems have a strictly locked Boot loaders, which is not the case with Android devices where Boot loaders are either open or easily unlockable.

Jailbreaking for the iOS thus also involves completely unlocking the Bootloader. Other than this difference, the iOS does not allow unsigned apps to be installed on iOS while on the Android OS unsigned apps can be installed after checking the ‘Unknown Sources’ option from Security settings.

Therefore, Jailbreaking for the iOS typically involves unlocking the boot loader, providing Administrator rights, and allowing installation of unsigned apps from sources other than the Apple App Store.

The future of rooting depends a lot upon the manufacturers and consumer interest. Apple and Microsoft do not promote rooting – Google on the other hand releases open source codes which can be used by any developer, and promotes rooting both through its devices and through open source projects. HTC, Sony, Asus etc. explicitly provide the user with the ability to unlock devices and replace/modify the OS.

A vast majority of smartphone users and all over the world believe that rooting is completely a personal choice of the owner of the device, and manufacturers should have no say in it, nor should they be allowed to prevent the user from modifying a device he owns. In most countries, India amongst them, Rooting/Jailbreaking smartphones for personal usage is an entirely legal procedure. Therefore, smartphone users in India can seek and implement root exploits and enjoy the benefits of elevated access and permissions on their devices without any concerns.

Article Summary


To calculate a square root by hand, first estimate the answer by finding the 2 perfect square roots that the number is between. A perfect square root is any square root that’s a whole number. For example, if you’re trying to find the square root of 7, first you’d need to find the first perfect square below 7, which is 4, and the first perfect square above 7, which is 9. Then, find the square root of each perfect square. The square root of 4 is 2, and the square root of 9 is 3. Therefore, you know that the square root of 7 falls somewhere between 2 and 3. Now, divide your number by one of the perfect square roots you found. For example, you would divide 7 by either 2 or 3. If you were to choose 3, your answer would be 2.33. Next, find the average of that number and the perfect square root. To find the average in this example, add 2.33 and 2, then divide by 2 and get 2.16. Repeat the process using the average you got. First, divide the number you’re trying to find the square root of by the average. Then, find the average of that number and the original average by adding them together and dividing by 2. For example, first you would divide 7, the number you started with, by 2.16, the average you calculated, and get 3.24. Then, you’d add 3.24 to 2.16, the old average, and divide by 2 to find the new average, which is 2.7. Now, multiply your answer by itself to see how close it is to the square root of the number you started with. In this example, 2.7 multiplied by itself is equal to 7.29, which is 0.29 away from 7. To get closer to 7, you would just repeat the process. Keep dividing the number you started with by the average of that number and the perfect square, using that number and the old average to find the new average, and multiplying the new average by itself until it equals your starting number. If you want to learn how to use the long division algorithm to find the square root, keep reading the article!
