The error “Install update zip failed” on Xiaomi: causes and solutions

The “Install update zip failed” error is one of the most common problems when trying to install custom firmware or an official update on Xiaomi, Redmi or POCO smartphones via TWRP or Mi Recovery. It can appear on older models like the Redmi Note 4X, and on new flagships like Xiaomi 13 Ultra. In most cases, the error is not due to damage to the firmware file, but to improper preparation of the device or version conflict.

In this article, we will discuss 7 proven ways to fix the error, including fixing the bootloader unlock, checking the integrity of the system. ZIP-file, reset and alternative firmware methods. MIUI, If you've tried to refashion your phone and you've got this error, don't rush it into service, because 90 percent of the time, you can solve the problem yourself.

Why is the error "Install update zip failed"?

The causes of error fall into two categories: software (related to software or settings) and hardware (memory damage, NAND module malfunction).

• 🔓 The bootloader is not unlocked – even if you’re sure you’ve unlocked it through the Mi Unlock Tool, some models are not unlocked (POCO F3, Redmi K40) Require additional verification of status.
• 📁 Damaged. ZIP-file downloaded from unofficial sources or with unpacking errors (MD5 or SHA-1).
• 🔄 Conflict of versions MIUI — attempt to install firmware older than the current (downgrade) or with another regional branch (eg Global on China).
• 🛠️ Incompatible TWRP — The custom recavator version does not support your model or Android version.
• 🚫 Active protection of Mi Anti-Rollback on new devices (Xiaomi) 12T, Redmi Note 11 blocks rollback on older firmware versions.
• 💾 Sectional problems /system — Damage to the file system or lack of space to unpack the image.

The most insidious reason is the hidden lock from Xiaomi, which is activated when you try to install firmware through Fastboot or EDL without authorization of your Mi Account. In this case, even an unlocked bootloader won’t help until you follow the additional steps (more on that below).

Method 1: Integrity check ZIP-firmware

The first thing to do is make sure the firmware file is not corrupted, and even if you downloaded it from Xiaomi’s official website or the XDA Developers forum, downloading or unpacking errors are common.

How to check:

1. Download the firmware file again (preferably via another browser or download manager).
2. Compare the checksum (MD5 or SHA-1) with the original.

certutil -hashfile rom.zip MD5

On Linux/Mac, use the command:

md5sum rom.zip

If the amounts don't match, the file is corrupted. Also note the extension: sometimes the archives are downloaded as.zip.zip (remove the extra by hand).

Method 2: Unlock the bootloader (Bootloader)

If the bootloader is blocked, TWRP or Mi Recovery will not be able to install firmware from ZIP. Xiaomi has complicated the unlocking process: now you need to link the Mi Account and wait 7-15 days (on new models).

Step-by-step:

1. Download the Mi Unlock Tool (the official tool from Xiaomi).
2. Log in to your Mi Account on your phone and tool.
3. Put your phone in Fastboot mode: adb reboot bootloader Or manually: turn off the device → pinch Power + Volume Down.
4. Connect your phone to your PC and start the Mi Unlock Tool, and if you see a message saying "Wait 168 hours," wait until the time is set.

⚠️ Attention: On Xiaomi models 12/13 Redmi Note 11/12 Unlocking may require additional authorization through SMS. If the instrument makes a mistake 0x80004005 — Try using another Mi Account or wait for the utility update.

Method 3: Bypassing Anti-Rollback protection

Mi Anti-Rollback is a security mechanism that blocks installing firmware older than the current version.It is activated on all Xiaomi devices released after 2019.If you try to flash MIUI 12 over MIUI 14, you get an Anti-Rollback check fail error or Install update zip failed.

How to get around:

• 🔄 Install an intermediate firmware (for example, if you have a MIUI 14, pass first MIUI 13, then the desired version).
• 🛠️ Use a modified one. TWRP with a patch for Anti-Rollback (e.g. OrangeFox or Sky Hawk Recovery).
• 📱 For models POCO X3, Redmi Note 10 and newer: Sweat a special ZIP-file for resetting the anti-rollback counter (see on the XDA model).

⚠️ Warning: Bypassing Anti-Rollback can lead to a device blink (completely inoperable) if done wrong. - Xiaomi models 11T And the newer method only works with EDL-Regime (requires an authorized account).

Method 4: Using the correct version of TWRP

Not all versions of TWRP are compatible with your Xiaomi model. For example, TWRP 3.6.0 may not work on Redmi Note 11 with Android 13, and TWRP 3.7.0 may not work.

Steps:

1. Find your model on the official website of TWRP or XDA Developers.
2. Download the latest stable version (avoid unofficial builds if you're not sure).
3. Install TWRP via Fastboot: fastboot flash recovery twrp.img fastboot boot twrp.img
4. After downloading to TWRP, do not restart to the system, but immediately install ZIP (otherwise, the stock recavator will overwrite TWRP).

If you load your phone into a stock recave after you install TWRP, you've got Anti-Rollback for Recover.

• 🔧 Please. disable_dm_verity_forceencrypt.zip (available XDA).
• 🔄 Install OrangeFox Recovery instead TWRP — It is better to bypass the limitations of Xiaomi.

💡

If the phone doesn't turn on after TWRP firmware, try slamming the Power + Volume Up for 10-15 seconds for a forced reboot. On some models (POCO F4), this works even with a soft brik.

Method 5: Formatting the /data partition

If the Install update zip failed error appears during the firmware unpacking phase, the problem may be in the damaged /data partition, which often happens after a failed firmware or reset.

How to fix it:

1. Download to TWRP.
2. Go to Wipe → Format Data.
3. Enter yes to confirm (all data will be deleted!).
4. Reboot to the recavéry and try to install ZIP again.

⚠️ Attention: Formatting /data deletes all user data, including photos, messages and applications. TWRP (Backup → Select Partitions → Data).

If the error persists after formatting, check the /system section:

adb shell


e2fsck -f /dev/block/by-name/system

Method 6: Alternative Firmware Methods

If the ZIP installation doesn’t work, try other methods:

For Fastboot firmware:

1. Unclose the downloaded file (should be in.tgz or.zip format).
2. Start the Mi Flash Tool, select the folder with the firmware.
3. Connect your phone in Fastboot mode and press Flash.

⚠️ Attention: Fastboot firmware on Xiaomi models 12T And now it requires you to disable signature verification:

fastboot oem edl

Method 7: Checking for hardware problems

If none of the methods worked, the problem could be in the hardware:

• 💾 Damaged memory (eMMC/UF) — check through TWRP (Wipe → Repair File System).
• 🔌 Faulty. USB-Port – Try another cable or port on PC.
• 🔋 Weak battery - if the charge is below 30%, the firmware may break. Charge the phone to 100%.

To diagnose memory:

1. Download to TWRP.
2. Go to Advanced. → Terminal Command.
3. Enter e2fsck -c /dev/block/mmcblk0p1

If the team returns a Bad superblock error, the partition is corrupted, and only the replacement of the memory chip (in the service center) will help.

💡

If the phone doesn’t turn on after a failed firmware, try pinching Power + Volume Up + Volume Down for 20 seconds – this sometimes works for forced reset on some Xiaomi models.
