There are a lot of things to try out to get the most out of the fact that Android is open source. In this way, it includes unlocking your device’s bootloader, which lets you do a lot of other things to fix it. These include being able to install a custom recovery like TWRP, flashing modules and frameworks, or even getting administrative rights in the form of the root. In the same way, you could also use custom ROMs to install a completely new and different OS that is based on Android. This is just the tip of the iceberg, though. There are a lot of tweaks and tricks out there for you to find.
And one of the most important things you need to do these customizations well is have a custom recovery like TWRP. There are a few tips that don’t need TWRP, like how to root your device without it, but for many others, TWRP is a must. Well, this custom recovery can now be used to do everything that could be done without TWRP. For example, it’s easy to flash the GSI build using fastboot commands, but we all know how messy this is. There are also a lot of other things about TWRP that make it a must-have for everyone.
But the thing is that this TWRP has bugs and errors. Back when it was competing with CWM (remember that?) it had a lot of bugs. But it has changed over time and is now the only custom recovery on the market. All the other modified recoveries you see on the Internet are based on TWRP. But even so, there is a problem that a lot of users are having recently. The TWRP Error 7 is what we’re talking about. We mentioned below are the ways to Fix TWRP Error 7 while installing custom ROM.
Ways to Fix TWRP Error 7 while installing custom ROM
Update your Bootloader
If the bootloader on your Android is out of date, you might also get the error 7 in TWRP when you try to install a custom ROM. So try to get the latest version of the bootloader for your Android device before you install a custom ROM.
Format & Remove the Cache
The best and easiest way to fix Error 7 in TWRP is to format your device’s cache partition. You can also format the data partition and the Dalvik cache. To do this, follow the steps below:
- Reboot the system in a device recovery mode such as TWRP (Team win Recovery project ) or CWM (Clockwork Mode Recovery).
- After entering recovery mode, you will be presented with a list of several options, select “Advanced Wipe“.
- Here you will select Cache, Dalvik Cache, and Data.
- Now wipe the selected partitions.
- If you have TWRP it will prompt a text bar, type yes init.
- This will format and delete the cache.
- After exiting the process, try again to flash the custom ROM.
Install Latest Recovery Version
With each new version of Android, the recovery tools also change, so if you try to install the newest version of Android with an older version of Recovery, you might get an error. Make sure that the version of custom recovery is also up to date. To find out, go to the TWRP website and download the latest version of the recovery programme for Android devices.
Remove Assert Checks
If you are sure that the ROM’s updater script file is correct and doesn’t need to be changed, you should try taking out the Assert checks. It will change the ROM package, which could be causing TWRP to show Error 7. Follow the steps below to do so.
- Copy the ROM zip file to your computer and unzip the archive.
- You will now have access to a folder called META-INF. Open it.
- Navigate to the line META-INF/com/google/android.
- In the last folder/directory you will find two files called “update-binary” and “updater-script“.
- Now rename “updater-script” to “updater-script.txt” and open it with any text editor.
- Now locate the line beginning with “assert” and delete it. Typically, this line is at the beginning of the content, usually next to the codename of the device.
- Now save all changes and again change the file from “updater-script.txt” to “updater-script“.
- ZIP the folder and copy it to your smartphone or tablet.
- Reboot your Android phone into recovery mode and retry flashing the custom ROM.
- TWRP error 7 or Status Error 7 is gone.
What is Error 7 In TWRP?
You can use TWRP to install third-party firmware and make a copy of your current system. You can easily wipe, format, install, or make a backup of your whole system with TWRP. It’s a great tool for anyone who wants to update the custom recovery on their Android device. TWRP Manager is a root app that lets you wipe, mount, back up, restore, install, and change the settings of your recovery quickly.
If your device can work with this option, then updating your system should be a little bit easier and faster. This error will happen when you try to flash a custom ROM on your Android or Tablet. It can also happen when you use CWM (Clock Work Mode) Recovery. As mentioned above, the error is caused by the wrong script file (the ROM updater-script file, which isn’t made for your product model). And you might have made this mistake because you skipped some important steps before.
