In order to make the banking app Vipps work on my e os FP3+ i came over this explanation for its installation on lieage os. I have tried the method, but can not make ADB edit system files.
I have opened ADB in command prompt on win 10 and can access the phone, but using the command mount --remount -o rw / i get the return ‘/dev/root’ is read-only. i can edit the file with VIM, but it cant write to the system.
Does anyone know how it can be done?
