<![CDATA[Issue installing UT Stable over old UT Dev installation. [Solved]]]>Hi.

This is a continuation/overlap from this thread: https://forums.ubports.com/topic/6857/no-flash-on-fairphone-2-camera

After going from Stable to halium-devel (to fix the non-working torch & camera flash issues) and not being able to go back to the Stable channel, I went to the Dev channel. I did an update on the Dev channel. It updated and then prompted me to reboot. It then got stuck in the reboot stage. Holding in the power button only made it reboot and then hang again in the reboot stage. I had to remove the battery to power it off.

I can't get into the Bootloader as the installer on my PC says to hold in the vol down button & power button when the phone is off.

I can get to recovery mode via holding down power & volume up buttons.
I get these options:

  • Reboot system now
  • Ubuntu actions
  • Android actions
  • Reboot to bootloader
  • View recovery logs

I went into Recovery Mode and selected the 'Reboot to bootloader' option. It's still in the screen from the linked image. I don't know if it had actually rebooted to the bootloader.

  • The phone was stuck at the boot splash.
  • Get to recovery mode and then run the installer.
  • The installer says 'Cleaning up' , 'Erasing cache partition'.
  • Put it back in recovery mode.
  • Click continue on installer.

🙂

  • Replace ubuntu android system
  • Install ubuntu zip
  • Install ubuntu preinstalled
  • Wipe data/factory reset

Am I left with only those options now?

I can't continue with the installer. I don't what to do next. ❓

I find tech support on Telegram to very awkward compared to opening a thread.

You mentioned these in our Telegram chat:

  • enable developer options
  • unlock oem
  • allow debugging
  • set to MTP mode

Are those 4 things to be done on my FP2? Any of those items apply to my Desktop PC?

Thanks.
