I just rebooted my phone and now it is not booting anymore:
It gets stuck during the blue boot animation and after a few minutes it enters a factory reset screen where I can choose from “Try again” and “Factory reset”.
Tried “Try again” several times without success.
SIM card is removed, no sdcard installed.
However, I do not want to do a factory reset, before I can make a backup of my phone data (my last full backup is half a year old).
The phone is running official Fairphone OS with bootloader still locked and it got the latest update a few days before.
How can I get the phone back running without loosing my data?
Is it possible to mount the data partition from within recovery and e.g. transfer files via adb?
I only found the option to enter adb-sideload mode from within recovery.
I for sure know, data partition is encrypted. But maybe there is some mechanism to decrypt it from recovery which I can successfully boot into?
I remember from earlier phones I used, that TWRP for example was able to mount the data partition and also to create backups directly to SD-card…
I wonder why a phone destroys its own file system while rebooting. Never had such an issue with any phone ever before.
I would need to add that some weeks ago my primary mic stopped working, which was the reason that I searched today in this forum and found out that with other people a comparable issue disappeard for some time after the phone has been rebooted. This was what I wanted to try.
Prior to the reboot I did the mic test from the service menu which indeed recorded only some noise from mic1, whereas mic2 was working properly.
Unfortunately, as of the locked state, the phone refuses to boot into TWRP using fastboot boot <twrp-image-file>.
As you suggested, I tried switching to the other slot (a):
which results in the phone rebooting directly into the “data corrupt / try again/factory reset” screen, so I switched it back to slot b.
In the above “TWRP for Faiphone 3” topic @k4y0z said:
How exactly to do this?
Sure, I still have my pin .
I guessed from the fastboot help output and tried fastboot fetch userdata ./userdata.img, but the phone answers, that fetch is not supported on this phone.
Would it help to again flash the latest OTA-Update with sideload mode?
the stock OS script is not made for this, or? so how to extract neccesary files? For any other ROM I guess you would have to “install” first another recovery? Not sure if this is possible through stock recovery via SD card?
hi, i have the exact same issue with my fp3 as the OP. wth is going on? is this some kind of hw problem?
since it is possible to enter recovery (at least in my case) where would i find the right file to sideload over adb? i downloaded FP3-REL-Q-3.A.0136-.gms-7c69ec7e-user-fastbootimage and decompressed it. not sure which one of those files should be used.
I just tried your solution, but it did not work for me, same behaviour after flashing the official package. Also tried SAFEMODE, same result.
Please update the link in your post, it is not pointing to the instructions but only the gpx-file:
I also tried to unlock, install TWRP, and re-lock bootloader again.
The phone is now telling me directly after power on, that it is corrupt and refuses to boot. After unlocking, it simply boots into TWRP every time - hm. Also, TWRP does not even ask for a PIN when mounting data partition - I don’t know why.
I have now given up to restore any data. Will try to install LineageOS now, because I lost my data anyway.
I’m really upset that a phone bricks itself. My wife is kidding at me for buying such a phone - “You should have bought a real one, HA HA…”
(Meanwhile I switched back to my old S3-mini to have a working telephone - this device is still working with a custom ROM after about 10 years!)
hi, sorry for the wrong link and i can not correct it anymore. @AnotherElk found the relevant post. thx.
so flashing the official package succeeded but the phone was still dead?
seems like nand corruption is common with modern phones nowdays.
Hi. This is my first post on this forum. I started following topics about unbricking fp3 just 2 days ago. A lot of learning… Thanks to everyone contributing and sharing their knowledge.
I have almost the same issue with my fp3 as unclelutz (including previous problems with microphone). Only difference is that my phone had suddenly reboot itself and never worked again since 2 days.
I will try to follow procedure which @flup did, within next few days. However before that I’d like to prepare and understand a bit more. I consider myself a novice in flashing process. I’d like to ask more experienced members of community a couple of questions.
Just to let you know that I did follow @flup 's solution, and it worked without any data loss
To answer @Adam.W 's questions, the .gpx files are generic, and I followed the official fairphone guide (i had to upgrade android as the device was on 10 and only last 11 release is available, it was not an issue). The bootloader was locked and ADB not activated.
So the workaround is this (I’m just regrouping the infos as I wasn’t totally sure of them) :
Boot into fastboot mode (hold Vol Down while booting)
Download devinfo-unlocked.gpx (1 MB)
-in a terminal with adb installed on your computer: fastboot flash devinfo devinfo-unlocked.gpx fastboot reboot bootloader
