sysmalloc: Assertion error while using the script

While using the script, I am getting this error:

Is there a way to fix it?

Sadly, this project is quite old and there is a chance this is crashing with latest images.

As you can see here the unpackbootimg is 6 years old now.
If you find an updated binary, it may fix your problem. If you fix, I would love a PR.

[pcboy]

It looks like the mkbootimg project was forked and updated.

You may try to recompile it and replace that unpackbootimg.

Thank you for the quick reply. I updated the binaries for x86_64 but now the result is this

Try to use the bin, unpackimg.sh and repacking.sh scripts from this repository instead.

Technically, the only part that really matters in my repo is: https://github.com/pcboy/adb-insecure-patcher/blob/master/adb_insecure.sh

It's just patching the ramdisk default.prop and then repack the boot.img.

[maddo7]

I think using this did the trick but now it seems your script fails because a file it not there.

I'm using a Samsung device. I checked the files of the ramdisk a bit and found this file: /ramdisk/etc/ramdisk/build.prop

The content is the following:

Could it be that this is the needed file? If not, could you tell me how I can find it?

I am completely new to Android devices and doing something with them.

I'm not super familiar with samsung roms. Usually at the root of the extracted ramdisk there is a default.prop. The build.prop is different iirc.
Is there no ramdisk/default.prop file at all or is it a symlink to /system/etc/prop.default by any chance? On xiaomi devices that's the case and it's then replaced in my script by a sample default.prop.
You can also try to search for ro.secure or adb.secure or ro.debuggable over all the files in the ramdisk/ folder and see if you get results.
