When trying to install a custom ROM on your phone, TWRP will sometimes give you an error that says “Error 7: Invalid or corrupt block chain.” This only happens when the ROM isn’t flashed correctly. Luckily, there is a fix and it’s easy!
The “how to fix error 7 twrp without pc” is a problem that has been present for a while. TWRP, the custom recovery software, will not work properly if you have this issue.
When flashing any Custom ROM, you get Error 7 in TWRP (e.g. Lineage OS). This problem typically affects rooted Android devices and tablets. The major reason of Error 7 in TWRP Recovery when flashing a Custom ROM is that the ROM’s updater script file does not include a model for your phone, or that the phone model is available in the script file, but that file is built for a different model or for functioning on other provider’s networks.
If you’ve encountered Error 7 in TWRP, don’t panic; we’ll go through how to fix it so you can flash any custom ROM with ease. So, let’s get this party started.
What is TWRP Error 7?
This issue may occur while flashing a custom ROM on your Android or Tablet, and it can also happen when using CWM (Clock Work Mode) Recovery. The issue is caused by the incorrect script file (the ROM updater-script file, which isn’t suitable for your product model), as previously stated. Another explanation for this mistake might be that you skipped some crucial stages in the past.
‘Error: 7’, ‘Status Error 7’, and ‘ZIP signature verification failed error’ are all comparable difficulties that occur when the ROM’s updater script file is corrupted or steps are skipped.
If you unintentionally loaded the incorrect ROM updater script that isn’t for your phone’s model, and you need to get the ‘native’ script, you may use the Assert method to prohibit you from downloading the ROM updater-script for another phone. Well, this problem will not affect your device; you can always go back and continue doing whatever you were doing, but if you want to remedy this mistake, let’s start with the TWRP error 7 fix.
Format & Delete the Temporary Internet Files (temporary Internet Files)
The best and simplest way to fix Error 7 in TWRP is to format your device’s cache partition. In addition, you may format the Dalvik cache and the data partition. To do so, follow the instructions below:
- Start your system in device recovery mode, such as TWRP (Team Win Recovery Project) or CWM (Custom Recovery Mode) (Clockwork Mode Recovery).
[Note: To enter Recovery mode, make sure Android is turned off. When you see the blank screen, simultaneously press the volume down and power buttons for a few seconds. You’ll now be presented with a menu of choices.]
- After entering Recovery mode, you’ll be presented with a menu of choices; choose Advanced Wipe.
- Select Cache, Dalvik Cache, and Data from the drop-down menus.
- Wipe the partitions that you’ve chosen.
- If you have TWRP installed, a text bar will appear, prompting you to write Yes init.
- The cache will be formatted and removed as a result of this.
- After you’ve completed the procedure, try flashing the custom ROM again.
Bootloader must be updated.
If your Android’s bootloader is out of date, you could get an error 7 in TWRP while installing a custom ROM. Before installing a custom ROM, make sure your Android device’s bootloader is up to date.
Assert Checks should be removed.
Remove Assert tests if you are positive that the ROM’s updater script file is accurate and doesn’t need to be changed. It will modify the ROM package, which might cause TWRP Error 7. To do so, follow the instructions.
- Unzip the archive after copying the ROM zip file to your PC.
- You should now be able to access the META-INF folder. It should be opened.
- Go to the line META-INF/com/google/android.
- Two files named “update-binary” and “updater-script” may be found in the final folder/ directory.
- Replace “updater-script” with “updater-script.txt” and open with any text editor.
- Locate and delete the line that begins with the word “assert.” This line is normally located towards the beginning of the material, next to the device’s codename.
- Save all of your modifications and rename the file “updater-script.txt” to “updater-script.”
- Copy the folder to your phone or tablet after zipping it.
- Restart your Android phone in recovery mode and try flashing the Custom ROM again.
- TWRP Error 7 (Status Error 7) is no longer an issue.
Install the most recent recovery version.
Because recovery tools change with each new version of Android, installing the current Android version with an older Recovery version may result in an error. Make sure the custom recovery version is up to date as well. To verify this, go to the TWRP website and download the most recent Android recovery version.
