flash zip fails with : Busybox setup failed

[SynapseScribe]

trying to flash ex (elemenatlalX) kernel zip, but after inflating zip, flashing fails with error:

update-binary
inflating: tools/magiskboot
inflating: tools/busybox
inflating: tools/magiskpolicy
Busybox setup failed. Aborting...

The detailed log shows: "Mounting root filesystem: Failed * Please Note: Flashing may not work properly on this device!"

However I am rooted with magisk and have allowed the app root access. Also I have "Busybox for Android NDK" magisk module installed.

It's a totally different issue (not related to root/busybox access for the app) that I'm struggling to deal with for a while. It sadly affects some modern devices. I guess you're in Android 10/11. From the technical side, the app will create a recovery-like environment and send the flashing command. The rest of the errors are from the anykernal installer (not the app). The issue is most likely related to the failed mounting /system partition. If you have time and interest, try manually mounting the /system partition (mount -o, remound,rw /system) and try to continue flashing. In case if you got the same mounting issue, try to find the exact path to system partition from /proc/mounts.

Yes, i am on android 10. However afaik you cannot manually remount /system in android 10 as is locked as read only.

Any updates on this issue? Kernel flashing is broken on Android 11....:-(
