Hi guys,
so I tried rooting my FP2 with KingRoot and SuperSuMe yesterday only to realize that it get’s stuck on the loading screen and doesn’t 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 isn’t 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 I’m 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 GSM… Unfortunately, I am no dev either…
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 don’t have a FP2 so I don’t 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 didn’t need to convert anything. Phone took something like 5 minutes to boot afterwards (probably running after-installation and setup scripts) but now it’s 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?, what’s 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 “apply update from sdcard”? I’m 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? I’d need to find a free µSD-card to test the “from sdcard”-approach. UPDATE: Found a suitable µSD-card and I’m currently copying the OTA zip file to it
Nope, sideloading the OTA-zip doesn’t work for me. I also tried different USB-cables. It might fail since the recovery I’m using is self-compiled using the instructions on http://code.fairphone.com but that’d be a strange reason.
I’ll tell you if it worked usind the sdcard as soon as copying finished.
If you’re 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
“Applying update via sdcard” also failed for me with both OTA zips (1.1.6 and 1.1.7) though the MD5s of the files match what’s in the updater.xml. Sadly I can no longer try using the original recovery system since I don’t have the .img (No one except Fairphone has, I assume). @lklaus: Sure I could disable that. I’m just wondering why it failes on the official updates released by Fairphone
interesting… I uploaded it via adb sideload and it worked on the very first try…
why would a custom recovery impact the installation of a standard rom? Doesn’t make sense to me…
@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 couldn’ 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 “install update from sdcard” and pointed to the ota.zip .
The phone installed it but after the reboot I got error messages like “google services are terminated” as well as Hangouts and more about google services.
I can’t 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 weren’t 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?
