If the screenshot above shows the content of the file in /system/etc/permissions then you’ll anyway need to replace the whole file 
In that case, just mark all, delete, copy all from my file and paste it. That should be sufficient.
I’d really like to do that. But I got no idea how to get your file into my phone. Tomorrow I’ll try the push for the last time. If that doesn’t work again I’ll try a factory reset. Will that make my phone work again?
If you use the amaze editor you won’t need to copy the file to the phone - that is, if you still can use your web browser. You only would need to be able to open the file and copy it’s content to replace the content of the corrupted file.
I am not sure though if a factory reset would do it, since to my understanding it only clears the /data partition, but the corrupted file sits in the /system partition.
Thanks for the information. Unfortunately the tint browser doesn’t work any more since the google services don’t run any more. So my only chance would be to write the file manually using your file that I downloaded.
Yes, it seems to be a bit tricky, but there are still a couple of possibilities.
Writing the file by hand would be one, but it’s quite some text to copy by hand, with the risk of making mistakes. However, if you’d just write enough by hand to mount one sdcard, you could push the file there and copy it into the right location.
Are any apps still running, or what apps do not run?
I was just thinking that if basically some apps can still run, it might be worth trying to install busy box via adb, which gives you the possibility to use either wget to download files from the internet (right to the location you want them to be), as well as vi to edit files through the terminal.
I would send the text of the originally pulled and “working” platform.xml via sms in small pieces.
Will that work?
What about the greater space between parts of strings. Is it important how much space there is?
I’ll upload the whole file so that you can see it.
Could you tell me, which parts are not necessary? So I don’t need 30 sms…
OK, upload impossible. So here is the content:

I only deleted exactly from the first <!- -… to the next - ->
That means that I didn’t delete any space between strings.
Is there a problem if there is to many space?
I never edited a xml-file before…
So next step would be the transfer via sms.
Because of the space between the strings the first 160 characters of a sms would look like this:
Or should I better count the amount o space between strings and insert that into the platform.xml in the permission-folder of my phone?
I don’t think that the spaces between the strings make any difference, so I would leave them out - so you have to send less text messages 
Seems like the sms-edited platform.xml (inserted only parts) doesn’t change a lot. How can i install busybox via adb and where do I get it? On the other hand: no apps are working but amaze. No internet.
Thought to send the phone back to the netherlands and let it repair by technicians of FP because it seems like I couldn’t solve my problem.
With “doesn’t change a lot”, do you mean no change at all? Or can you access now at least some drive (like internal or external storage).
Basically it should work if the corrupted file gets fixed.
Well, if you can’t get apps running, maybe installing busy box won’t work either. At least the busy box app which I am using is rather an installer that - when opening the app - downloads the necessary components (binary).
For an adb install you basically need to download the apk file to your computer, and with the command “adb install FILENAME” you can install it. Though I am not sure if that will work if you cannot get root access for the adb.
I think if everything fails then you still have a chance to get a running system by yourself. You could download the stock ROM and flash it from the recovery, or you could ask someone who compiled the FP-OSOS if he or she could provide you with the images.
Thanks again for your kind help!
No, I can’t mount the storage or the external card and no app is working.
So I would like to flash the stock rom which I downloaded now. Afterwards I could use your platform.xml again that you kindly provided for me
But I couldn’t find a wiki for flashing the rom for beginners in the forum in a quick search. Is there one?
Hey,
I just saw you already opened up a new thread for continuing on your system rescue mission!
Anyhow, I am not so well versed with flashing and stuff, so I hope others can be of more help. Maybe you can ask @Moritz, he managed to get a softbricked FP2 working again with the OTA zip.
Good Luck!
Hi there,
I’ve installed open camera and configured the storage location to an existing folder on my external sd card. however the app doesn’t seem to have write permissions there. In the file manager I can change permissions but they doesn’t seem to be permanant.
Any clues?
Regards
Android 5 doesn’t grant general write permissions for the SD card.
With a rooted phone this problem can be fixed. See, for example, posts 2, 3, or 27 in this thread for different solutions.
Oh yeah I distinctly remember something now. Seems I’ve enjoyed Cyanogenmod for too long ;). Anyway thx for pointing that out. Lets see if I can root my new FP2 w/o having a brick 
Yeah, there are many great features from CM that I miss on Android.
Anyhow, rooting isn’t too difficult. See https://forum.fairphone.com/t/pencil2-howto-root-with-superuser/12375
Cool as it turns out rooting the FP2 is almost the same thing as rooting a Samsung device. Not I’m the “king” of my phone with write permissions to my sdcard sweet! 
Now let’s see what we can do about the notification LED color thing
Again thanks for the swift help!
