FP2 Bricked - Recovery Help

[barney]

Thank you Moritz, Irina and IKlaus for your kind help and also Freibadschwimmer!

None of the fastboot commands could be executed. The only thing that at least BEGAN to do something was the partition command. But of course () it failed.

I found again the recovery wiki for the FP1 and executed it as I did it before by installing the ota.zip from the sdcard in recovery mode.
The new thing to me was the advice to now execute the factory reset AFTER the reinstalling!!!
And that worked!
After a despaired week I got a working phone again and of course I’ll root it now
Jesus bless you all!

If you’re using a self compiled recovery you might as well disable the zip file verification.

How is that done? Does one have to edit the source code before compiling?

[lklaus]

Yes, yolu’ll have to do some patching. It’s written in the wiki post [HOWTO] ✏ Compiling Fairphone Open OS / Rooting

I’m glad you got your phone to work again! And to get general writing access on your SD card, try https://play.google.com/store/apps/details?id=nextapp.sdfix . It works well and there’s no risk to brick your phone again .

[barney]

Thank you, Irina,
sorry, I don’t use google any more.
I tried again with adb push and pull. But again that didn’t work because of insufficient user rights as far as I understand it.
But I followed Freibadschwimmer’s hint (?, jedenfalls: seinen Tipp ), to edit the platform.xml with the Amaze-Editor. Worked phantastically without brick
Good night!

or you can take the easy route and just flash a finished twrp recovery from this threat

Porting TWRP recovery

This is a wiki post. Everyone can improve it, by clicking the green pencil above. This topic was originally about porting TWRP to the Fairphone 2. Reference information on how to use TWRP on a FP2 has been moved into this topic: Using TWRP on the Fairphone 2. The post below does not contain up-to-date information Today I started looking into TWRP recovery and made good progress. I want to share my experience, patches etc. here with you. Maybe there are some interested people (I know ther…

[freibadschwimmer]

I’m glad to hear you have a working phone again, and finally managed to get write permissions for the SDcard. So in the end all your patience and persistence on solving the issue paid off. Well done!

Hi,
I softbricked my FP2 and had contact with the support but they seam not to be happy at all, about some people try to change their system.
The reply was that i should better not push them. (i rewrote them that i didn’t get an answer within 8 days, so i wrote again and asked if my question wasn’t clear or if they need more information…)
Seams not that i will get help from the Fairphone support Team so im asking here…

What i wold like to have is any OS on my phone. Doesn’t mater if its a Fairphone OS or a FreeOS.
The momentary status is, the phone doesn’t boot now. I can see the chargerscreen (batery geting filled blue) when pluged to a wallcharger. But normal booting doesn’t show any screen at all (stays black and doesn’t vibrate when pwr button pressed).
But im able to get in to fastboot mode some times and i can get the device nr. with fastboot devices so i think it not totaly broken.

I found some informations about loading binaries to a FP1/1U but not for FP2.
http://forum.xda-developers.com/wiki/Fairphone_Fairphone/Guides#Bricked_your_Fairphone.3F
Are the binaries to be released soon or are there licence problems that will prevent that totaly?
And what i don’t understand is why i need a tool to load binaries like that:http://mtk2000.ucoz.ru/load/soft/soft_mtk/sp_flash_tool/5-1-0-14
Is that not possible in fastboot mode?

Thanks for any help.
Regards, Novski

Hi @novski, did you tried to perform an hard reset ?
You need to boot your phone in recovery mode (not fastboot)…

[novski]

Hi,
i forgot to say that i can not reach recoverymode anymore…

[fp1_wo_sw_updates]

Hi, I softbricked my FP2 and had contact with the support but they seam not to be happy at all, about some people try to change their system.

I’m sorry to hear that. As long as you can still connect using fastboot installing the offical FP2 OTA image should be possible. Have you tried that already?

[novski]

Hi, Thanks for the help…
what i did: I loaded this file to the sdcard:
http://storage.googleapis.com/fairphone-updates/FP2-gms36-1.1.7-ota.zip
and performed a flash from sdcard. Unfortunately after that, the phone showed the withe screen “loading…” for 3-4h befor i pushed the pwd button and the phone whent black and a reboot or recoverymode wasn’t reachable anymore.

[fp1_wo_sw_updates]

I think you or I might confuse recovery/fastboot. Can you still boot the phone into the fastboot mode or the recovery? How does that look like? How did your fastboot command line looked like?

If fastboot still works: Try to install a recovery first
If recovery still works: Try to install the OTA (works with the default recovery) or the Stock Android (needs different recovery).

I’m not sure if the OTAs are complete “full” FP2 software versions (1.1.5, 1.1.6 and 1.1.7 exist) or just partial upgrades. If all fails, I (or others) can send you a recovery that should be able to install the stock Android. But it’s important to know what your phone can still do and how it can be “reached”.

[novski]

Im not able to reach recovery
Im able to reach fastboot and see a device nr. with fastboot devices
I wold love to get a recovery and install a stock Android.
Thanks!

[fp1_wo_sw_updates]

Im able to reach fastboot and see a device nr. with fastboot devices

Try this first:
Installing stock Android + recovery: You can just install the stock Android (no other recovery needed) using the stock build images (they contain recovery.img*, boot and system) using fastboot flashall.

If all that works, you can try the TWRP:
TWRP-recovery: Can you ask @Moritz | @Max_S (!) for a link (23 days old! Don’t use this one, maybe there is a better one out there!) to his latest recovery?

[Moritz]

Hey there,
the link is not by me, but by @Max_S. He ported the TWRP recovery and as far as I know it’s the latest version. I flashed it just 4 days agp and it worked fine on my FP2, so if there is no valid recovery on the phone at the moment, I would second @fp1_wo_sw_updates’s suggestion on putting one there. I believe I mentioned that earlier in this threat somewhere already
I believe, the ota does not include the recovery, so probably flashing the TWRP and then using it to flash the ota stock system is the best way to go…
Good luck and keep us posted!

[novski]

Hi, and many thanks for the Help here.
If I wold get the .img files - whats the order to flash my phone?
Do i start with the recovery.img or wit the boot.img and what all do i need to flash. Whats required?

[fp1_wo_sw_updates]

Do i start with the recovery.img or wit the boot.img and what all do i need to flash. Whats required?

Normally fastboot flashall takes care of all that if the files are around and as long as the phone is in fastboot mode and “reachable”.

[tphysm]

Well, I don’t think that the order is that important (but I’m not entirely sure). I’d try

$ fastboot flash boot boot.img
$ fastboot flash recovery <insert name of TWRP recovery image here>
$ fastboot flash system system.img

If that doesn’t work, replace the last command by

$ fastboot -w flash system system.img

or even flash more images as some people have tried with self-compiled versions:

[HOWTO] Compiling Fairphone Open OS / Rooting

The error itself is not a problem, it happens on stock and on my own build too. Have you tried flashing the images one by one ? On top of "flashall" (which I don't use, I flash each image sequencially) I also flashed cache.img and userdata.img (just to be sure, it should be enough to wipe them but I did it anyway).

[HOWTO] Compiling Fairphone Open OS / Rooting

I flashed these images in sequence: boot, cache, persist, recovery, splash, system and userdata. Still it won't boot. Can check additional logs? How do OS developers debug these errors? Does the fact that I am still able to flash it mean that there is hope that the phone can eventually be rescued?

Edit: @fp1_wo_sw_updates If that’s possible, nice! Though I thought fastboot flashall only works if you have a build environment which was set up properly (with android-info.txt present and so that flashall knows which device to flash etc.).

[novski]

That file:

android-info.txt
