How to Fix TWRP Error 7 (While Flashing Custom ROM via TWRP)

In this tutorial, we will show you how to fix the TWRP Error 7. To soak in the advantages of the Android open-source nature, there are quite a few things to try out. In this regard, it includes unlocking the bootloader on your device, which in itself opens the gate to a plethora of other fixes. These include the ability to install a custom recovery like TWRP, flashing modules, and frameworks, or even getting administrative privileges in the form of the root. Likewise, you could also install a completely new and different OS based on Android in the form of custom ROMs. Well, this is just the tip of the iceberg. There exists an ocean if tweaks and tricks waiting for you out there.

And to effectively carry out these customizations, one of the major prerequisites requires you to have a custom recovery like TWRP. Granted there exist a few tips that don’t require TWRP (like rooting your device without TWRP), but for countless others, TWRP is a must. Well, even the things that could be carried out without TWRP are now being done via this custom recovery as well. For example, you could easily flash the GSI build via fastboot commands, but we all know how messy it is if we choose this route. Furthermore, there exist tons of other features of TWRP that makes it an absolute necessity for all of you.

However, the thing is this TWRP isn’t free of errors and bugs. In earlier times when it was competition with CWM (remember it?), it had quite a few bugs. However, with time, it has now become a beast and the only custom recovery in the market. All the other modified recoveries you see across the net are based on TWRP itself. But despite that, there exists an issue that quite a lot of users are facing as of late. We are talking about the TWRP Error 7. If you are also facing the said issue, then this guide will help you out. Today, we will show you how to fix the TWRP Error 7. Follow along.


How to Fix TWRP Error 7

You might have faced this error while flashing a custom ROM on your device. Status 7 Error is caused when the ROM’s updater script file checks to see if our mobile is compatible with the ROM we are installing, called “asserts”. Asserts is a safety mechanism that keeps a check that we don’t end up installing an incompatible ROM on your device. because if you did so, you might end up with a bricked device.

Although this safety mechanism is quite an important component, yet the issue is that nowadays, users are getting this error even while flashing the correct build of the ROM. This infuriates quite a few users and rightly so. After all, if you are installing a Custom ROM based on your device, then you shouldn’t be facing this error in the first place. But if you are, then fret not. In this guide, we will show you how to fix the TWRP Error 7. Let’s begin.


Here are a couple of things that you will be needing

  • Any unzip software (7ZipWinZip, etc)
  • A Text Editor Software (Notepad++, we would recommend not to use the Windows default Notepad app).

That is it. Now follow the below steps to fix the TWRP Error 7.


To begin with, extract the custom ROM that is giving out this error, onto your PC.

extract custom rom


Now head over to the META-INF folder. Then go to com >> google >> android. There you would find two files:  “update-binary” and “updater-script”. Rename the “updater-script” file to “updater-script.txt”

Next up, right-click on the updater-script.txt file and select Open with. Then from the menu, select the Notepad++ app.open via notepad


You now have to delete the lines starting from the word “assert” to the next semi-colon. Usually, this portion is on the top only as shown below:

delete asserts twrp error 7

Once you have removed the highlighted texts, your first line should start from the ‘mount’ word. See the below image for reference.

asserts deleted


Once you have deleted the aforementioned section from the file, save it. Once that is done, rename the “updater-script.txt” back to “updater-script”.


Once the rename is done, re-compress all the files as shown below.
