How to unburp Xiaomi Redmi 6: 5 working ways (2026)

Introduction: What does it mean to “unscrap” a smartphone?

The term “brick” in the Android world refers to the state of the device in which it completely or partially ceases to function. Xiaomi Redmi 6 can turn into a “brick” after a failed firmware, resetting through TWRP, interrupted MIUI update or experiments with unlocking the bootloader.

The main problem with Redmi 6 owners (codenamed cereus) is the lack of official support from Xiaomi after 2021, which means that standard tools like the Mi Flash Tool may not work with the latest versions of Windows or require workarounds. In this article, we will discuss 5 proven recovery methods, including working through Fastboot, mode. EDL, and hand-stitching SP Flash Tool (for MediaTek Helio processors) P22).

Before you start, make sure your problem really relates to the brick:

• 🔴 Soft brick: The phone turns on but gets stuck on the logo or reboots cyclically.
• 🟠 Hard brick: The screen is black, but the computer detects the device in the Fastboot or EDL.
• ⚫ Full Brick: No button reaction, PC doesn't see phone even through Device Manager.

1. Diagnosis of the problem: we define the type of "brick"

The first step is to understand how badly the firmware is damaged, and then do the following:

1. Try going to Fastboot, press Power + Volume down for 10 to 15 seconds, and if you see a picture of a hare that says Fastboot, you have a soft brick.
2. Check the charging response: connect your phone to the charger, and if the charging indicator flashes or burns, the problem is more software.
3. Connect to your PC: Install Xiaomi drivers (link in the next section) and check if the device in Device Manager is defined as Qualcomm HS-USB QDLoader 9008 (EDL mode) or Android Bootloader Interface (Fastboot).

If the phone doesn't respond to any of the actions, there may be hardware malfunctions, such as damage to the motherboard, a memory chip dump, or power problems, in which case a diagnosis is required at the service center.

2.Tool preparation: what will be needed for recovery

Depending on the recovery method, you will need:

Important: download firmware only from trusted sources. Files from torrent trackers or obscure forums may contain viruses or be corrupted. For Redmi 6, current firmware versions are:

• 📱 Global Stable: V12.5.1.0.PCGMIXM (last official)
• 📱 China Stable: V12.0.4.0.PCGCNXM
• 📱 Custom firmware: LineageOS 16 (Android 9) or Pixel Experience (requires unlocked bootloader).

💡

If you downloaded the firmware in.zip format and you need.tgz for Mi Flash, rename the file extension manually. WinRAR or 7-Zip Archivers are not required!

3. Method 1: Fastboot Recovery (for soft brick)

This is a good way to go if the phone goes into Fastboot mode but doesn't load beyond the logo. We'll use the official Mi Flash Tool utility.

Step-by-step:

1. Install the Mi Flash Tool and Xiaomi drivers (see previous section).
2. Unpack the downloaded firmware (.tgz) into a folder without Cyrillic characters (for example, C:\ROM\redmi6).
3. Press on the phone power + Volume down to enter the Fastboot.
4. Connect Redmi 6 to your PC via USB.
5. Launch the Mi Flash Tool, press Select and point the path to the unpacked firmware.
6. At the bottom, select Clean All (Full Cleaning) or Clean All and Lock (Cleaning + Lock bootloader).
7. Press Flash and wait until it is completed (5-10 minutes).

If the process ends with a critical partition doesn't exist, the partition table is corrupted, in which case you go to the EDL recovery method (section 4).

⚠️ Note: If you select Clean all and lock mode, the phone bootloader will be locked, which means that you can install custom firmware (for example, custom firmware, TWRP) Re-unlocking via Mi Unlock Tool will be required, which takes up to 720 hours of waiting on new Xiaomi accounts.

How to log into EDL:

• 🔌 Turn off the phone. USB.
• 🔧 Close the test points on the motherboard (if the phone is not included in the EDL For Redmi 6, the dots are located next to the headphone jack:

1. Remove the back cover (need a mediator or plastic card).


2. Find two gold contact areas that say "EDL" or "TEST".




3. Close them with tweezers or screwdrivers while connecting the USB- cable to the PC.

If done correctly, the device will appear in Device Manager MediaTek Preloader USB VCOM Port (for MediaTek) or Qualcomm HS-USB QDLoader 9008 (for Qualcomm).

Firmware via SP Flash Tool (for MediaTek):

1. Run the SP Flash Tool and download the scatter.txt file from the unpacked firmware.
2. In the settings, select Download Only (if you want to save data) or Firmware Upgrade (complete flashing).
3. Press Download and connect the phone in EDL mode.
4. Wait for the green circle with the inscription OK (the process takes 3-7 minutes).

⚠️ Attention: If SP Flash Tool is an error S_FT_ENABLE_DRAM_FAIL (4032), So the firmware is not suitable for your revision of the motherboard, try a different version of the firmware or check if the contacts are not leaving when closed test points.

5. Method 3: Unlock the bootloader (if the phone is not sewn)

If previous methods have not worked, it is possible that the phone has locked the bootloader, and the official firmware refuses to install, in which case you will need to unlock through the Mi Unlock Tool.

💡

If the unlock fails due to the error "Current account is different from the account info on the device", then the phone was previously linked to another account, in which case only a request to support Xiaomi with proof of ownership of the device (check, box) will help.
