No cellular network when backup and restore userdata.img
Added by 59iosl30 - almost 2 years ago.
Updated almost 2 years ago.
Device:
Galaxy S 3 (I9300)
Description
I tried to migrate to another GT-I9300 as described here: [[https://redmine.replicant.us/projects/replicant/wiki/BackupTheDataPartition]]
When I did a full backup of /dev/block/mmcblk0p12 on the source GT-I9300:
$ adb pull /dev/block/platform/dw_mmc/by-name/USERDATA ./USERDATA.img
The target device GT-I9300 is fresh installed and resetted to factory defaults.
After restoring USERDATA.img:
$ adb push USERDATA.img /dev/block/mmcblk0p12
Everything works except the mobile network. The sim card is detected and can receive sms messages, but there is no cellular network when:
$ svc data enable
If I do a full factory reset on the target device, the cellular network works again. How do I get the cellular network working again after restoring the USERDATA.img ?
Can anyone reproduce this issue ?
No cellular network when backup and restore userdata.img - Added by 59iosl30 - about 1 hour ago
I tested it on another GT-I9300 device with the same result. The mobile data did not work after a full backup and restore of the partition from a working device (even with mobile data) to another device. Resetting the network settings on the restored device did not help either.
After a full factory reset, the mobile data on both devices are working again. It looks like a setting or file in /data or even in /system is different or does not fit to the restored USERDATA.img.
Does anyone have a hint on what I can try ?
Kind regards,
Robert

If you are experiencing issues similar to these, performing a factory reset might help resolve them. There may be settings or files within either your /data or system directory causing incompatibilities when trying to restore USERDATA.img file.

Thank you, but as I already mentioned, a factory reset solves this problem, but all accounts, apps, app data and system settings are lost. This is not what I want. I want to manually fix this issue to keep the restored backup, but currently I don't know which files and/or settings are causing this problem.
Can you reproduce this issue on your phone ?
Kind regards,
Robert
