This might be exactly the reason why the full update file doesn’t exist. The problem with Android 6 and root is not just - as with Android 5 - that the incremental update doesn’t work, but that the app optimization process after the update will fail if the device is rooted/modified and therefore you’ll end up in a boot-loop.
I guess the only way it’s safe to release a full update file would be if that file automatically unmodifies the device first.
Well and sorry if the remark is silly, since I was able to to the update from Android 5 to Android 6 with a rooted phone without any problem whatsoever, the installation of android 6 does work from a rooted device as soon as the update is re-installing the full system (which was the case in the 17.04.3), I suppose I may do the same thing again from Android 6 to Android 6?
I know my case is quite specific but, I’ve done the update to 17.04.3 when it was public but no suppose to, otherwise I would have update from 1.13 to 17.04.8 and I guess, had no issue as I’ve had no issue from 1.13 (rooted and encrypted) to 17.04.3 (rooted and encrypted).
Thanks.
Do you have any further information / sources about this? That does not seem plausible to me.
Fairphone will not release a full OTA for 17.04.8, but the binary images are available. Just flash them via fastboot. That’s what I did; worked like a charm. (No, you won’t loose any data.)
Try setting a new screen lock password (you can use your existing one of course). If your phone is encrypted, you should be prompted whether to “Require password to start device”.
Sorry for the question, im a beginner, but what does “Run flash.sh/flash.bat” mean? I stuck at that point. If I just doubleclick the flash.bat file it says that the fastboot command can’t be found.
Hi, you overlooked 2 lines above mentioned “Get fastboot running as described in Step 1 here”. It is a portion of Android developer tools.
With the mentioned activities you flash a new image which does not require the Google way which works only with regular, non-rooted devices and leaves you without root afterwards. If you have not missed being root before, you won’t need those extra steps.
hi amber, thank you for the answer! i didn’t skip the fastboot step. i really just dont know how to start the flashing process, i tried some different commands like “fastboot flashall c:\Users…\flash.bat” but nothing seemed to work. so i juat need help with getting the flash.bat running!
thank you in advance!
The problem is, that the FP devs didn’t deliver a full OTA-Package yet (and I don’t think they will), only incremental images (which don’t work with rooted devices). I don’t know why.
I don’t think this will happen for 17.04.8, but maybe for the next version. Then yes, my autobuild-server only works with the full OTA packages.
I managed to install Android 6 and the rooted boot.img with fastboot now. I also have twrp recovery back, and now i wonde rif its possible to install gravitybox MM? Does someone have experiences?
@retsifp:from which version did you upgrade? I’m still on 17.04.1 (rooted, XPosed and so on :P) and I wouldn’t like to loose time going through 17.04.3 if I could directly jump to 17.04.8.
Thank you Bye!
