The Xiaomi Redmi Note 2, also known as Prima, is still a popular device among enthusiasts due to its maintainability and an active developer community. One of the first steps to expand the functionality of the gadget is to replace the stock Recovery with a custom TWRP menu. This allows you to get full access rights, make backups of the entire system, install custom firmware and modify system files.
The installation process requires careful and careful follow-up to the algorithm, as any errors can lead to the failure of the device. In this article, we will discuss in detail all the stages of preparation, the necessary tools and the installation procedure itself. It is important to understand that interference with the Bootloader software and memory partitions carries certain risks.
Before you start, make sure you're aware of your responsibility, and we'll look at not only the successful scenario, but also the typical problems that users face when working with this particular generation of MediaTek processors.
Preparation of the device and necessary tools
The first step is to collect all the necessary components to work. You will need the Xiaomi Redmi Note 2 smartphone itself, which is serviceable. USB-cable (preferably original or high-quality analogue) and a computer running the Windows operating system. TWRP, Specially adapted for Prima, as versions for other devices may not start or damage partition markup.
A critical point is that there are ADB and Fastboot drivers installed. Without them, the computer will not be able to properly interact with the phone in boot mode. MediaTek-based devices often require additional MTK VCOM drivers that allow the system to see the phone even when it is off.
☑️ Checklist for firmware preparation
Remember to back up all your important data, and when you manipulate the recovery partitions, the internal drive may be deleted or unavailable, and keep your contacts, photos, and documents in the cloud or on an external storage medium.
Unlocking the Bootloader bootloader
Installation of custom recavator is impossible without first unlocking Bootloader. In Xiaomi smartphones, this protection mechanism prevents unauthorized modification of the system. For Redmi Note 2, the procedure may be different from modern models, since older devices often support unlocking through special utilities or even test points, but we will consider the software method.
⚠️ Attention: The process of unlocking the bootloader will result in the complete removal of all data from the internal storage of the smartphone.
First, link your Mi Account to your device via the developer menu, activate the developer mode by seven clicks on the build number in Settings → About Phone, then select Mi Unlock Status and anchor from the developer menu, and then wait for a certain period of time, which can be between 7 and 30 days, depending on Xiaomi’s security policy at the time of the procedure.
After the waiting period, download the Mi Unlock Tool to your computer. Launch your phone in Fastboot mode, pressing the volume and power buttons simultaneously, and connect it to your PC. The utility must identify the device and allow you to unlock. Successful completion of the process is confirmed by the corresponding message in the program and on the smartphone screen.
Installation of drivers and Fastboot mode
The correct work with Fastboot depends on the quality of the drivers installed. In Windows Device Manager, when you connect an unlocked smartphone, the Android Bootloader Interface device should be displayed in the appropriate mode. If you see an unknown device or error, you must manually update the drivers through the Device Manager, indicating the path to the folder with the SDK Platform Tools installed.
To check the connection between your computer and your phone, use the command line. Go to the tool folder and type a command to check the connection. If everything is set up correctly, you will see the serial number of your Redmi Note 2 in the list of connected devices.

USB-port, preferably connecting the cable directly to the computer motherboard, bypassing USB-It's also worth checking if debugging is on. USB In the developer menu, although for Fastboot mode this is not always a strict requirement, unlike the mode. ADB.
The TWRP Recovery Firmware Process
When the preparatory steps are completed and the phone is in Fastboot mode, you can proceed to directly record the image. Place the TWRP image file (usually with the.img extension) in the same directory where the fastboot.exe executable is located. This will simplify the input of commands and reduce the risk of path errors.
In the command prompt running on behalf of the administrator, type a command to run the recovery partition firmware. Please note that some versions of the Redmi Note 2 may require firmware immediately after the command so that the menu is not overwritten by stock when it first boots.
fastboot flash recovery twrp-prima.imgAfter successfully executing a command that will take only a few seconds, you need to immediately put the device into recovery mode.Do not let the system boot normally, otherwise Stock Recovery can automatically replace TWRP. To do this, press the combination of power buttons and increase the volume immediately after the firmware is completed, holding them until the Mi logo appears, and then release the power button, continuing to keep the volume.
💡
If the TWRP menu does not start after the TWRP firmware, try immediately after the flash command to execute the command fastboot boot twrp-prima.img for a temporary download.
TWRP Setup and First Actions
The first launch of TWRP on Xiaomi Redmi Note 2 may be accompanied by a request for confirmation of changes to the system partition. Swipe the Allow Modifications slider to allow changes. This is a critical step, without which the recovery will not allow you to write in memory.
Next, you need to clean up the data, especially if you plan to install custom firmware or if the previous unlock of the bootloader was not done correctly. Go to the Wipe section and select Format Data by entering the word yes for confirmation. This action will delete all data and remove encryption if it was applied.
| Action. | Description | Risk of data loss |
|---|---|---|
| Wipe Dalvik / ART Cache | Cleaning the virtual machine cache | No. |
| Wipe Cache | Cleaning the system cache | No. |
| Wipe Data | Complete cleanup of user data | High-pitched |
| Format Data | Formatting the data partition (removing encryption) | critical |
Once cleaned, you can move on to installing SuperSU or Magisk rights if required for your purpose. Simply copy the zip archive to the device and install it through the Install menu in TWRP. For Redmi Note 2, installing patches for camera and sound in custom firmware is also relevant.
Possible mistakes and ways to solve them
During the modification of the Xiaomi Redmi Note 2, users often encounter an Error 7 error when trying to install firmware or a situation when the phone goes into an endless restart (bootloop), often due to incompatibility of the TWRP version and the Android version, or with a damaged boot partition.
⚠️ Warning: If the phone has stopped responding to buttons and is not in Fastboot mode, you may need to open the case and close test points to enter Emergency Download Mode (EDL).
Another common problem is a broken sensor in TWRP. This is solved by installing a special version of the Recovery labeled "Touch fix", or firmware sensor patch through ADB. For the Prima model, there are specific builds where this bug has already been fixed.
What if your computer doesn’t see your phone in Fastboot?
Also worth mentioning is the problem with internal memory. In some versions of TWRP, the Data partition can be displayed as 0 MB. This is treated by formatting data through the recovery menu, as described in the previous section. After formatting, the phone must be rebooted once to create the file system again.
💡
Successful installation of TWRP is only the first step, and the stability of the smartphone depends on the compatibility of the installed firmware and modules with the version of the recovery.
