I have a phone running Android Marshmallow (6) and apps constantly crash. Most apps I would like to use do not support Android 6. I would like to update to a custom ROM or a newer version.

  • adb and fastboot work
  • fastboot mode and recovery mode do not work
  • the device does not have too

How can I proceed? I find it's sort of chicken and egg problem with no recovery and no root. To be clear, I can't even get into stock recovery. The phone is Xperia Z2. Flashtool works but I can't find any newer versions of FTF files.

  • Some of the steps may be relevant: {Root}{Sony Xperia Z2}{MM}{23.5.A.0.575} unlock bootloader, root and ROM flashing

  • read about FOTAkernel and get help on official support thread on xda-developers

  • There are constant notifications that an app has stopped working. Any idea how I can stop these so that it's easier to work on the phone to get root? I had to dirty flashing a FTF and think these errors happen because the version of Android is older and doesn't support them.

  • You can ignore those message or perform a factory reset. When unlocking the bootloader a factory reset will be performed anyway.

  • Is there a way to backup the apps and (more importantly) their data using adb without root?
