Xiaomi Redmi 2: Official and Custom Methods (Updated in 2026)

Xiaomi Redmi 2 (codenamed HM2014811 or wt88047) is the iconic budget smartphone of 2015, which is still used by many users. However, with the release of new versions of Android and MIUI, official support has long been discontinued, which means that owners have to update or reflash the device themselves. In this article, we will analyze all the current ways to update Redmi 2 in 2026, from official updates via MIUI Updater to install custom firmware through TWRP and Fastboot.

It’s important to understand that firmware is not only a way to get new features, but also the risk of turning your phone into a brick if something goes wrong, especially with Redmi 2, which has a closed-loop bootloader and a specific CPU architecture (Qualcomm Snapdragon 410), and we’ll go through each step in detail, including unlocking the bootloader, choosing the right firmware version, and solving common bugs like the Error 7 or Anti-Rollback.

Preparation for firmware: what to do before the start

Before you start firmware, make sure that all the preliminary steps are followed, which minimizes risks and simplifies the process.

First, back up all your data. The firmware erases your internal memory, including photos, contacts, and apps. Use Mi Cloud, Google Account, or physical copying on your PC.

• 📱 Contact (export to) VCF-file)
• 📷 Photo/video (copy to computer or cloud)
• 🔑 Passwords and SMS (use SMS Backup & Restore)
• 🎮 Game saves (if the game supports cloud backup)

Second, check the model and the firmware version. There are several modifications to Redmi 2.

• 📱 Redmi 2 Standard (HM2014811) – 1 GB of RAM, 8 GB of memory
• 📱 Redmi 2 Pro/Prime (HM2014812) — 2 GB of RAM, 16 GB of memory
• 📱 Redmi 2A (HM2014813) – simplified version for India

You can find out the exact model in Settings → About Phone → Model or through the command fastboot getvar product.

Third, charge the battery at least 60 percent, and interruption due to discharge can make it impossible to turn on the device without service equipment.

• 🔌 Micro-USB cable (original or qualitative analogue)
• 💻 Windows PC 7/10/11 (for Fastboot and Mi Flash Tool)
• 🛠️ Qualcomm and ADB Drivers (download from Xiaomi official website)

Unlock the bootloader on Redmi 2

Without unlocking the bootloader, installing custom firmware or modified versions of MIUI is impossible. Xiaomi ties the unlock to the Mi Account, so the process takes up to 72 hours (sometimes longer).

Instructions for unlocking:

1. Connect your device to your Mi Account in Settings → Accounts → Mi Account.
2. Activate USB debugging: go to Settings → About Phone, tap 7 times on the MIUI Version, then in Settings → Additional → For developers, turn on USB debugging.
3. Download Mi Unlock Tool (version no lower than 5.5.224.24).
4. Connect your phone in Fastboot mode (clip Volume Down + Power when the device is off).
5. Run the Mi Unlock Tool, log in and follow the instructions. If you see a "Couldn't unlock" error, wait until the specified time (usually 72-360 hours).

⚠️ Warning: Once the bootloader is unlocked, all data, including internal memory (data and cache), will be reset, and some features (such as Mi Pay or Find Device) may stop working.

If you plan to install only official firmware, unlocking is not necessary – they can be flashed through Fastboot or Recovery without unlocking, but with restrictions (for example, you can not roll back to the old version).

Xiaomi Redmi 2 firmware methods: which one to choose?

There are three main methods of Redmi 2 firmware, each of which is suitable for different purposes:

Let’s look at each method in more detail.

1. Firmware via MIUI Updater (the safest way)

This method is suitable if you want to upgrade to the latest official MIUI version available for Redmi 2 (usually MIUI 9 or MIUI 10 based on Android 5.1/6.0).

Instructions:

1. Go to Settings → About the phone → System update.
2. Click Update Checker. If the update is available, download it.
3. After downloading, click Reboot and install.
4. Wait until the end (usually 5-10 minutes).

⚠️ Warning: If the update doesn't come automatically, try downloading the full firmware package (.zip) from MIUI Downloads and installing it via Select the update file from the update menu. Don't use firmware for other models, this will cause an Error 7 error.

2. Firmware through Recovery (TWRP)

To install custom firmware (e.g. LineageOS, Pixel Experience) or modified versions of MIUI, you will need TWRP Recovery. This method requires an unlocked bootloader.

Steps:

1. Download TWRP for Redmi 2 (the version should match the model!).
2. Install TWRP via Fastboot: fastboot flash recovery twrp-3.7.0_9-0-wt88047.img fastboot boot twrp-3.7.0_9-0-wt88047.img
3. In TWRP, make a backup of the NVRAM partition (important for IMEI!).
4. Download the firmware (.zip) and transfer it to your phone.
5. V TWRP Choose Install → Select a file → Swipe to Confirm Flash.
6. After installation, run Wipe → Format Data (if required).

⚠️ Warning: Redmi 2 has an issue with Anti-Rollback protection. If you're trying to install firmware older than the one that's already worth, the phone will lock. Check the Anti-Rollback version in Fastboot with the command:

fastboot getvar anti

And compare it to the firmware version.

3. Firmware via Fastboot (Mi Flash Tool)

This method is used to restore the phone after a crash or install the official firmware "from scratch", suitable even for "bricks", but requires accuracy.

Instructions:

1. Download the official firmware for Redmi 2 (select Fastboot, not Recovery!).
2. Unpack the archive into a folder without spaces and Cyrillic (e.g., C:\Redmi2_Fastboot).
3. Install the Mi Flash Tool.
4. Connect your phone in Fastboot mode (clip Volume Down + Power).
5. In the Mi Flash Tool, select the firmware folder and press Refresh. The device must be determined.
6. Select Clean All (complete clean) or Clean All and Lock (if you want to lock the bootloader back).
7. Press Flash and wait until it is completed (5-10 minutes).

⚠️ Warning: If the Mi Flash Tool gives you a "Flash is not done" error, try:

• 🔌 Use the other USB-port.
• 🔄 Reinstall Qualcomm drivers.
• 📁 Move the firmware to the root of the disk C:\.
• 🔧 Run the Mi Flash Tool on behalf of the administrator.

💡

If the phone doesn't turn on after you've run through Fastboot, try clamping Volume Up + Power for 10-15 seconds, which sometimes helps you get out of the soft brick.

Typical errors in the firmware Redmi 2 and their solution

Even if you follow the instructions accurately, you can get errors, and we'll look at the most common ones and how to fix them.

1. "Error 7" error in TWRP

Reason: Trying to install firmware that isn’t designed for your Redmi 2 model.

Decision:

• Check out the phone model (fastboot getvar product).
• Download the firmware specifically for your modification (Standard/Pro/2A).
• If the error persists, edit the updater-script file in the firmware archive by deleting the line with the model verification.

2. Hanging on the Mi logo after firmware

Reason: kernel incompatibility or lack of Wipe Data.

Decision:

• Download to TWRP and run Wipe → Format Data.
• Go through the clean installation.
• If it doesn’t work, try another version of the firmware.

3. "Anti-Rollback" error in Fastboot

The reason: trying to roll back on an older version of MIUI.

Decision:

• Check the current version of Anti-Rollback with the fastboot getvar anti command.
• Download the firmware with the same or newer version of Anti-Rollback.
• If the phone is locked, contact the service center for flashing through EDL- mode.

4. Mobile network or Wi-Fi is not working after firmware

Cause: damage to the NVRAM partition (stores IMEI and module settings).

Decision:

• Restore the NVRAM backup from TWRP.
• If there is no backup, try manually flashing NVRAM through the SP Flash Tool (you need a backup from your working device).
• Check the IMEI with *#06#. If it resets, restore it with the Maui META or SN Write Tool.

Firmware through EDL- Mode: Last Chance for Bricks

If the Redmi 2 is not enabled, is not detected in Fastboot, and is not downloaded to Recovery, the last method is firmware via EDL- Mode, which requires special hardware or an authorized Xiaomi account.

Instructions:

1. Download firmware in.mbn format (for example, with 4PDA).
2. Install the Qualcomm HS-USB QDLoader 9008 drivers.
3. Connect the phone to the PC by holding both volume buttons (the device should be defined as QHSUSB_BULK).
4. Use the Mi Flash Tool or QFil for firmware.

⚠️ Warning: Firmware via EDL without Xiaomi authorization can result in a complete locking of the device (an official unlock key is required). On Redmi 2, this method does not always work due to the outdated version of the bootloader.

If you do not have experience with EDL, it is better to contact a service center. the cost of restoration usually does not exceed 1000-1500 rubles.
