Hi guys,
so I tried rooting my FP2 with KingRoot and SuperSuMe yesterday only to realize that it getās stuck on the loading screen and doesnāt boot anymore. So I did some research and found this and this, both related to the FP1, but I figured the procedure qould be the same in general.
So I can boot into recovery and open an adb connection from my windows PC, all I seem to be missing, is a fresh ROM to flash to my phone via sideload. Where would I get one?
I actually do have a second FP2 at hand and I figured I might just backup its ROM and flash it to my other FP2, but I did not find a way to extract it without changing the recovery and since the second one isnāt my phone I was too scared to brick it as well by fiddling around with its recovery.
So any help you guys can give me is highly appreciated at the moment, as Iām still quite new to the Android world
Thanks and best regards,
Perhaps @paulakreuzer could tell you more. If I remember correctly he softbricked his phone by deinstalling all GSMā¦ Unfortunately, I am no dev eitherā¦
Well what I did was simply a hard reset. That got me so far that I could boot up the phone again, so - to undo the rest of the damage I did - I could reinstall the OS through the updater App.
Okay,
where would I get the proper system.img to flash it to the phone? Another user was so kind to send me his build of the FP2-osos, but if I try to flash it via adb sideload I get:
Is this really needed? I think the device should be able just use FP2-gms36-1.1.7-ota.zip (on a SD/sideloaded) from the recovery. But I donāt have a FP2 so I donāt want to say anything wrong.
It actually did work!
It just took me some time downloading the package but flashing works as it is and I didnāt need to convert anything. Phone took something like 5 minutes to boot afterwards (probably running after-installation and setup scripts) but now itās very vanilla again!
Thanks for the link to the ota-update @root and thanks for the support @USB-2
It think the is currently a lot of confusing info floating around (What does the recovery verify?, whatās inside the ota? Does a full backup work? Shameless plug: I think the best source for info right now is the wiki here, if one does not want to read all the threads in the forum.
So, how did you actually do it? Copy the .zip to an SD card, boot the recovery and use āapply update from sdcardā? Iām currently trying to send the .zip via sideload but when the PC is at ~40% the phone cancels the process:
I verified the MD5 of the ota-zip with the one from the updater.xml and they match.
Is there a file size limit for sideload? Iād need to find a free ĀµSD-card to test the āfrom sdcardā-approach. UPDATE: Found a suitable ĀµSD-card and Iām currently copying the OTA zip file to it
Nope, sideloading the OTA-zip doesnāt work for me. I also tried different USB-cables. It might fail since the recovery Iām using is self-compiled using the instructions on http://code.fairphone.com but thatād be a strange reason.
Iāll tell you if it worked usind the sdcard as soon as copying finished.
If youāre using a self compiled recovery you might as well disable the zip file verification. I think this is only a hassle and does not serve any real purpose
āApplying update via sdcardā also failed for me with both OTA zips (1.1.6 and 1.1.7) though the MD5s of the files match whatās in the updater.xml. Sadly I can no longer try using the original recovery system since I donāt have the .img (No one except Fairphone has, I assume). @lklaus: Sure I could disable that. Iām just wondering why it failes on the official updates released by Fairphone
interestingā¦ I uploaded it via adb sideload and it worked on the very first tryā¦
why would a custom recovery impact the installation of a standard rom? Doesnāt make sense to meā¦
@Moritz
Hey,
Freibadschwimmer suggested to me to ask you for help here
I made some mistakes concerning getting write access to my sdcard
Now my phone is dead and I tried to recover it but I couldnā succeed.
Which mistake have I done?
Could you help me to restore my phone?
I am a beginner!
Though I first stored the FP2-gms36-1.1.7-ota.zip on my sdcard.
Then I booted into recovery mode (at least I think so) and chose āinstall update from sdcardā and pointed to the ota.zip .
The phone installed it but after the reboot I got error messages like āgoogle services are terminatedā as well as Hangouts and more about google services.
I canāt finish the setup wizard because of the failure messages (google services are
terminated) and the wizard itself gets terminated. These messages began before flashing after a mistake in editing the platform.xml because the storage and the external sdcard werenāt recognized any more.
Did I make any mistake concerning the flashing?
I guess that the storage partition has to be recovered or created new?
I want the phone to be as it was delivered. What else do I have todo?
Could anybody help me because I am a bit despaired about my newe phone and begin to get hopeless.
Do I have to send my phone back to FP?
