Did you confirm TWRP 3.3.1-0 is really installed now?
TWRP not wanting to install Open GApps would be a behaviour of the older TWRP version bundled with Fairphone (Open) OS currently.
After a newer TWRP got installed, you have to reboot right into the newer TWRP to let it make itself resident. If the OS gets rebooted first instead, it will restore its own older TWRP version.
A workaround in case of problems with this would be to boot a newer TWRP without flashing it, see twrpwoflashing .
I just figured that TWRP is updated after going into recovery mode right after installing the TWRP update. When I then reboot my phone and then boot it in recovery mode again, the update is gone again. Do you have an idea why?
When you boot a newly installed TWRP, it will ask you to allow modifications to the system partition, else it canāt prevent to be overwritten again.
Did you allow this?
Canāt think of anything else, installing TWRP worked reliably for me so far.
Concerning the ZIP to install, you will have to make sure that āZip signature verificationā is disabled in TWRPās settings. Normally thatās the default.
You mean installing Open GApps (TWRP doesnāt come as a ZIP file, itās an IMG file)?
If you have fastboot working, you should have the adb command, too.
You could put TWRP into ADB Sideload mode and try whether adb sideload ing the ZIP file from the computer to the phone makes a difference.
I use Fairphone OS, this means I donāt need OpenGapps, right?
Battery drain has been a problem since one of the updates. Donāt remember which one. Long ago. I waited for the next update (the one which took months). Itās become worse as time passes by.
Iām fed up of regressions.
Iām sure, my next phone wonāt be a FP, but another Android refurbished one. I changed from refurbished iPhone to FP. I wonāt change OS again.
I tried everything!
The whole battery guide. And as Iām rarely on route, mostly can charge it. But otherwise, I doesnāt last a half day, if I use it (Firefox, whatsapp, e-mail, etc.)
The worst is camera (different apps used and not being able/difficult to focus, if close to the object) so I donāt take pics anymore. Just, If battery is over 60% and Iām able to charge in near future,as sometimes a pic costs 20-30% battery, but not always)
Opening Whatsapp if battery is lower than 30% is also like āsuicideā
I donāt even know, if itās worth, trying with a new battery anymore
Also, since I changed the bottom module, it doesnāt āBrummā, when connecting without battery to āresetā, so I donāt know if it really"works".
Iām afraid of updating every time. I think, It canāt become worst and it might fix a bugā¦ and then came the wifi problem (changing place, new wifi wonāt show), the 1%d screen (which is not just cosmetics as asserted at the bugtracker, as it is time consuming and annoying, if something is needed prompt), the wallpaper changeā¦
Bought End Jan 2018. Then the motor in the new bottom module is broken? But the phone vibrates when in vibration modus. It doesnāt vibrate when I connect it to the charger without the battery (as explained in the battery guide)
Iām sorry, I misunderstood that. If your vibration works otherwise, then the module should be OK.
Which battery guide did you use? This one does not mention vibration. There might be other suggestions in that guide which are worth a try.
The rest of the story sounds like a broken battery. Iāve seen that old batteries can suddenly start to discharge quickly when a power-hungry app is opened - probably caused by a sudden drop in voltage. Your problem is similar but more extreme.
I finally managed it to update TWRP it properly! When now trying to install open_pps-arm-7.1-pico-20191114.zip it tells me that the Zip file is corrupt. I also tried to install older versions of Open GApps but then it told me that I must download the correct version for my ROM: 7.1.2 (SDK 25). Do you know what to do?
Could the message be correct and the ZIP file really be corrupt? Did you download it again and/or check the MD5 checksum?
Else ā¦ TWRP would be left to check, I guess. Iām not a big fan of the TWRP 3.3.x branch for encryption reasons, but I donāt remember problems simply installing ZIPs with these versions.
Anyway ā¦ If it was me with this problem, I would try 3.2.3-0 for comparison ā¦ not only because it has proven to be rock-solid and stable, but also because you donāt even need to flash it, you can just download a signed TWRP 3.2.3-0 image and boot it without flashing it, see #twrpwoflashing ā¦ ideal for a quick, unintrusive test.
