today I’m stuck using TWRP to backup and recover. First of all, my phone should be sent to france for repair. So what do I do without my phone? This simple case shows, that the level of redundancy is not sufficient. Today it shows, that the number of fairphones I own, directly affects the system reliability inverse proportional…
However, this is, what I did with phone A:
- Removed old backups from SD-card
- Reboot to TWRP
- Backup to SD-card
- cp -r /data/media /external_sd/
- Remove SD-Card and insert into the computer
- rsync -av /sd-card /whereever
- Remove SD-Card and insert into phone B
- Boot into TWRP
- Wipe everything (but not the SD-card…)
- //edit: I forgot to mention, that I create a new backup and delete it afterwards, just to make TWRP create a backup folder for the new device. Then, I copy the real backup to the newly created folder.
- Restore (seems to work well so far)
- rm -r /data/media
- cp -r /external_sd/media /data/
- chown -R mediadrm:mediadrm media
However, after reboot it stucks in the boot process with the fairphone logo, leaving the CPU temperature at 75 °C. I even tried to spare the last three steps and tried to restore the backup at phone A and now I don’t have a working phone at all; both phones don’t boot.
Does anyone have any idea, what I might did wrong or can help me to restore my phone(s)? Did I miss something? I worked with Nandroid-Backups several times before and they always seemed to be so very reliable. Now one might say something like “Your backup files were broken”, but then I wonder, what are backups good for, when they only work occasionally? Any suggestions?
