After updating my FP2 to 1.4.2 via the updater app (and later, manually again from the SD card), and rooting it using super-booting, I seem to have lost my data connection.
Google Play Services crashes
Chrome says I’m offline
The updater app says it can’t download a config file
Anybody seen anything similar? What to do about it?
No, it’s not just the mobile data connection, it’s ANY data connection (the above logical excerpt was taken when connected to a WLAN). I rooted using super-bootimage.
But the problem persisted after re-updating via SD card (and not rooting).
Any firewall / security app / Xposed modules that could have become active? (e.g. afaik AFwall won’t work until you have root access. So maybe this became active when you rooted the phone?)
So now I have found the time to bite the bullet and do a fresh install of the OS (using method #4 from the “Manually install FP OS for the FP2” page with FP OS 1.3.6, and then do the update to 1.5.1 from the SD card).
Everything is working again, and thanks to Titanium Backup Pro I have all my apps and their data back - but not the launcher setup, screen layout etc.
Okay, so I think I get an idea of what went wrong.
FP was working properly for some time. Then, Titanium Backup said it couldn’t complete the scheduled backup (to the old SD card directory). The complete error message wasn’t visible in the notification, but I think it complained about not having enough free space.
Thinking this had to do with the SD card access issue, I applied the proposed change to /system/etc/permissions/platform.xml. After rebooting, my problem was there again: no network access whatsoever.
Right now, I’m going through the restore steps again. So far, my FP2 after updating to 1.5.1 does have internet access. I’ll then try to dig deeper into the Titanium Backup failure without going down the permissions path again.
I have read this thread today and for me it sounds similar to No internet at all. There I described my problem and what I have done before.
Because you have written in this thread that you had changed /etc/permissions/platform.xml (i.e. /system/etc/permissions) before the problem appeared I remember that I have done the same to fix the Ext SD card permission issue.
Maybe some ways changing platform.xml are dangerous. If I remember rightly I have copied the file from PC to FP2-ExtSDCard and further copied the file with ghost commander (file manager) to /system/etc/permissions for which I had to remount /system with RW option. Probably I have forgotten to remount with R option after that and this was the failure.
For me its too late because I have reflashed my FP2 with Open OS 16.06 but I wanted to write down my experience for other users.
UPDATE: Today I have changed platform.xml as described in SD Card no writing permission in FP2 (mind the missing read permissions) and the phone is still running
UPDATE 2: Sorry but this wasn’t a solution. Again my phone was unusable (no network). Recommending doing changes to platform.xml only in recovery mode. See SD Card no writing permission in FP2
