Revision history [back]

I was trying to help a friend to recover a phone booting only to background after updating to 1.1.6.27. Recovery mode worked, so first we tried option 5 which did run through but didn't help. Then via option 4 (Shell) we tried to backup data before reset, but mounting the memory card failed after commands

mkdir -p /mysd
mkdir -p /myhome
mount /dev/mmcblk1p1 /mysd

The card in phone was normal MicroSDHC 8GB. I advised my friend to contact care, but I wanted to write here too to confirm if there's something changed in the mounting steps or if the latest upgrade has a new bug on this.

Additionally, in the beginning we also checked btrfs fi show which showed both enough of storage space and allocation space free, so I have no idea why the update didn't go through in the first place.

SD card is confirmed to work on PC, and confirmed to be formatted to fat32.
