I’d be really glad for any hint concerning my problem:
I tried to perform the latest OS update, but got an error message, I think it was “Partition for path ‘/system’ not found, Full SELinux support is available”.
I tried to reboot the phone and ended up in TWRP again.
I read about the possibility to manually install Fairphone OS. The big problem is the fact, that I had to use a workaround to make my computer recognize my Fairphone 2 with Windows 10, I had to switch on the debugging mode to enable it to connect to my computer via Phone Explorer.
Now that I’m stuck in TWRP I can’t do that anymore, so my computer doesn’t recognize my phone, thus leaving me without the possibility to install OS manually!
Does anybody have an idea what I can do to be able to use my phone again, besides trying to use another computer to connect it?
I’d be really happy about the smallest seeming hint!
Please follow the steps to the letter and tell us where you get stuck, if you get stuck, this doesn’t rely on the phone being fully available to file explorers or sync programs on the computer, it uses fastboot mode, as @urs_lesse already hinted at …
Thanks for your replies!
Yes, the phone can be switched to fastboot mode, the mode where I only see the Fairphone logo and the LED flashes blue, right?
There are not many steps I can follow. I can either end up in fastboot mode or in TWRP and whenever I reboot the system I end up there again.
I even inserted the SD card to my pc, copied the data for the last available update to it and tried to load one of the images in the folder, which may sound stupid, because I didn’t really know what I was doing, but I was desperate to try anything to render my phone usable again… I don’t have the faintest idea how I can proceed now…
Oh, latest news, now my phone seems to be stuck in fastboot mode. When I try to connenct it to my computer, I hear the windows jingle telling a device has been connected, but the phone doesn’t show up in Windosws Explorer. The device manager says, there is a “Kedacom USB device”, but I can’t interact with it.
Is there anything I can do now to proceed?
Finding https://www.recoverandroid-data.com/blog/fixed-android-stuck-in-fastboot-mode , I followed the steps to find out whether my android device would be detected there. Using the command “fastboot devices” the programme found the device “3a8fb644” . Does this help somehow? I feel like a blind person stumbling through an unknown room and try things not knowing if this might be helpful…
On my virtual odyssey trying to find anything that could turn this now unusable slab of plastic and metal into a usable phone again I tried to install Android Multitools to see if this could do anything for me. However, when I tried to extract the files the programme asked me for a password for this file although it was nowhere to be mentioned that I would need one.
I’m on the verge of giving up and asking my local compuer and smartphone specialist store to see if they can save my phone…
Founf out the password is simply “androidmultitools.com”. The programme works, but it also cannot help me to get out of fastboot mode.
I have a friend in Freiburg who’s experiencing serious trouble after a failed update from 18.09.2 to 19.02.1… System gets stuck on first Fairphone logo, it goes to fastboot but does not get recognised in fastboot by several computers (which is why this tutorial fails: https://support.fairphone.com/hc/en-us/articles/207914363-Manually-install-Fairphone-OS-for-the-Fairphone-2)
We tried installing via TWRP (we’re running 3.1.1-0), but TWRP gives us the error message “Unable to find partition for path ‘/system’” and when we try installing anyway, we get “Zip signature verification failed” even though we deliberately disabled zip signature verification. In the “Wipe” menu, we performed a standard “Data, Cache and Dalvik” wipe, but this hasn’t helped. In “Advanced wipe”, we don’t see “System”, so we can’t perform a “clean wipe” either to just get it over with and reinstall the software.
Good thing is, we were able to save the data within TWRP by copying it to an external SD. But I have to admit that I’m done with my knowledge and have no idea how to get the phone working again without doing a complete wipe of the internal memory. I’m not sure that would actually help, as I fear that the “/system” partition mission indicates a larger underlying issue.
@urs_lesse or the others reading here, do you have any idea what the next steps could be?
Thank you very much. I encountered the same problem after failed update.
This reanimated my phone.
One strange thing was that TWRP complained on reboot that “there is no OS installed and
reboot will fail” (likewise). But after rebooting everything looks fine.
With older firmware there was no blue LED flashing in fastboot mode, so this could be normal depending on the OS version you’re coming from.
Whether your laptop “doesn’t see the device” depends on the definition of “see”.
When in fastboot mode, file explorers or sync programs will not be able to “see” the phone. The fastboot command on the laptop, however, should be able to “see” it.
Try the steps 1. and 2. here to get fastboot going … and report any errors with this …
The problem I seem to have is that when I try to enter the Bootloader or Fastboot mode, though I have the the opening screen ‘Fairphone’ display, there is no blue flashing notification light which appears to be a requirement of this mode. When I connect to my laptop there is an unusual tone - not the usual device connected tone and when I run the manual install, I repeatedly get the “WARNING: No Fairphone 2 found in fastboot mode”
If you happen to have #fairphoneangels in your vicinity, they could perhaps try to help you out in person.
Else … ok, using Windows then? We’re getting there .
So you downloaded the Android SDK Platform Tools and extracted the downloaded ZIP file to somewhere you can find it.
There’s a folder namend “platform-tools” there now.
While in Explorer, click on this platform-tools folder to display what’s in there.
Click into the location bar at the top of the Explorer window, enter “cmd” there (without the quotation marks) and hit Enter.
There’s a screenshot of this here in the " Using CMD command in File Explorer to open Command Prompt Window" section.
This should have opened a command prompt in the platform-tools folder now.
Thanks for your help. I’m using a very old laptop running Vista and think that’s probably the cause of my struggle to make your instructions work!
I’m hoping to use a MacBook tomorrow and fingers crossed that will be successful.
No, Win7 should still be fine (until April 2020).
In order to be able to help, we’d need to know exactly, what you did, which step failed and what the related error messages say.
Else it won’t be possoble to provide remote support.
If you are more familiar with MacOS it’s definitively worth trying with a MacBook. In case of issues please point out clearly which OS you are using to avoid confusion (on all sides).
Tried to install update.
Phone entered Team Win Recovery.
Tried manual install following Fairphone support advice.
Repeatedly get “WARNING: No Fairphone 2 found in fastboot mode”.
Downloaded Android SDK Platform Tools following AnotherElk’s advice.
Not sure how to continue from here… Uncertain on instructions given…
More clear/basic direction for non tech person would be much appreciated!
No access to Mac at present, so sticking with Windows 7 if it should work.
