on my FP2 with /e/, the screen rotation doesn’t work (anymore). If I remember right, it worked in the beginning right after installation. But now, when I activate it, it doesn’t turn anymore, even shaking doesn’t help. Very annoying for OSMand or videos…
Thanks for the link, @volker, I haven’t found this. Glad you searched it up for me!
So @stanzi, if I read right in this topic mentioned above and this one: Installing from scratch is not scratchy enough, you formatted your phone, installed UBports, then formatted again and installed LOS? Afterwards all the sensors worked again? Sounds not very logical, but if it works…
I also tried to flash both LOS and OpenOS multiple times before, along with formatting the entire phone (except TWRP probably), reflashing TWRP multiple times, flashing the drivers via the modem file, but nothing worked.
It doesn’t sound logical to me either, but it worked, so I didn’t question it
Man, so I spent the whole afternoon with that. I’ve managed to install UBports with their buggy installer (I’d love to type some lines in the terminal… ). I tested two different kinds of sensor apps, screen was not rotating in UBPorts and no sensors working. Well, I thought you had it only afterwards, so I tried to install /e/ again… I can’t access TWRP now, I can only start it with adb. I have always the UBports logo in the recovery mode. /e/ is installed successfully, but no sensors work…
thanks for your answer.
In fact, I’d like to have TWRP back again and accessible by the hardware-buttons. So I installed TWRP again, but it doesn’t work… Fastboot works, I can even install /e/ with it (which works, but not the sensors). But adb seems not to connect… For adb reconnect it gives no devices/emulators found back… And I am still with the UBports recovery…
How can I uninstall that?
Ah, I think I see a possible problem.
The “Fastboot Install Method (No Root Required)” begins with the device booted and with Android running.
Forget the “adb reboot bootloader” part and just start or reboot the phone while keeping the Volume - button pressed to boot the phone into Fastboot mode (aka bootloader).
Then you can continue at “You should now be in fastboot mode” .
ADB works when Android is running and USB debugging is enabled in the settings … and it works when TWRP is running, but only with a subset of the possible commands … and recovery programs tend to support ADB Sideload to install stuff, but you have to switch them into receiving mode for ADB Sideload first, so the computer can push the install file to them.
By successfully installing TWRP, or any other recovery program.
I don’t recommend formatting the recovery partition because it simply is not necessary … and you would still have to install a recovery program if you want to have a working recovery mode.
Fastboot is not recognizing your phone.
Is the phone connected to the computer and booted in fastboot mode (only the Fairphone logo is displayed, with current modem files additionally the blue LED would be blinking and at the start the phone would have vibrated a few times)?
