• 📱 Incompatible version TWRP. Outdated builds don’t support Dynamic Partition (introduced in Android 10).
• 🔧 Damaged partition table after failed firmware or reset via fastboot.
• 🚫 Blocked bootloader (even after official unlock through Mi Unlock Tool, restrictions may remain).
• 💾 Hardware memory problems (wear and tear) eMMC/UFS, controller errors).

For example, on the Redmi Note. 12 Pro+ s MIUI 14 This error often occurs because TWRP Cannot work with a new format super.img, which Xiaomi uses to merge partitions.

If you plan to format memory, be sure to back up important data through ADB Or an external memory card (if it is determined). To do this, connect the phone to the PC in mode. TWRP and do it:

adb pull /sdcard/ path on pc

On some devices (e.g., Mi) 11 Ultra: internal memory may not be installed even through ADB In this case, the only way to save the data is to use the Mi Flash Tool to restore the firmware without cleaning. /data (if the partition table is not damaged).

Method 1: Entering a password to unlock encryption (FBE)

Starting with Android 9, Xiaomi by default includes file-based encryption (FBE), blocker /data into TWRP. Even if you have a lock screen disabled, the system can use a standard lock screen. PIN-code default_password.

4. If the command fails, try an alternative method: echo]" > /tmp/password_file twrp decrypt /tmp/password_file

On some devices (e.g. Redmi) K40) You may need to turn off the encryption completely:

• 🔄 Go through the stock. MIUI via Mi Flash Tool with clean all and lock check (this will delete all data!).
• 📱 After booting the system, do not configure the lock screen and immediately unlock the bootloader again.
• 🔧 Install. TWRP and format /data how F2FS or EXT4 (not exFAT!).

⚠️ Attention: On devices with Android 12+ (for example, Xiaomi 12T) Disabling encryption can cause problems with the work of Google Pay and banking applications. TWRP with support for decryption (for example, assemblies from SKKK).

Method 2: Formatting of the section /data filesystem

If decryption doesn’t help, it’s likely a section. /data It is corrupted or has an incompatible file system. on Xiaomi devices with Dynamic Partition (Android) 10+) standard formatting TWRP It often doesn’t work – you need to use special teams.

If the process ends with an error anti_rollback, So you're trying to run an older version. MIUI, It's more than the one that was installed earlier:

• 🔍 Check the current version MIUI Getvar Anti via fastboot.
• 📥 Download the firmware with a higher number (for example, if you have a firmware number). V13.0.4.0, take V13.0.6.0 or newer).
• 🔧 If there is no suitable firmware, use it. TWRP To install an anti-rollback patch (e.g., from Xiaomi Firmware Updater).

After successful firmware, unlock the bootloader again (if necessary) and install TWRP repeatedly.

💡

If the Mi Flash Tool gives an error critical partition flashing is not allowed, it means that the bootloader is locked. Unlock it through the Mi Unlock Tool before the firmware.

Method 5: Checking for hardware problems (if nothing helps)

If all software methods have been tried, but the Unable to mount storage error persists, hardware malfunctions are possible, and on Xiaomi devices, this is most often due to:

• 💾 Memory wear and tear eMMC/UFS (Especially on budgetary models after 2–3 years).
• 🔌 Problems with the memory controller (for example, after a fall or overheating).
• 🔋 Unstable power supply (discharged battery or faulty charging controller).

How to diagnose hardware problems:

1. Check Memory Health with fastboot: fastboot devices fastboot oem emmc_info If there are lines in the answer Life Time: 90% or below, memory is worn out.
2. Read/write: Fastboot oem emmc_test Mistakes. Read/Write Failed indicates a malfunction.
3. Check the power: fastboot oem battery_voltage Voltage below. 3.5V It may cause failures in installation.

If the diagnosis confirms a hardware malfunction:

• 🔧 Replacement eMMC/UFS — requires ration and is worth 30–70% It is economically viable only for flagships (Mi). 11 Ultra, Xiaomi 12 Pro).
• 📱 Using an external memory card – if the problem is only with the internal drive, you can flash TWRP on SD-map and work through it.
• ♻️ Recycling – on budget models (Redmi) 9A, POCO C31) repairs are often unprofitable.

⚠️ Note: On some devices (e.g. Redmi Note 8 Pro with memory) UFS 2.1) problems with mounting can be caused by overheating of the controller. Before repairing, try to cool the phone (put it in the refrigerator for 10-15 minutes) and try mounting in the device again. TWRP.
