Resolution of application loss in a2sd+ state detailed resolution _android

In this case, ten to one is the SD memory card ext partition error, repair errors after the reboot can re-enable a2sd+, retrieve the original installed application

As with repairing a FAT partition, this can be done by fsck, and the Run command changes from Fsck_msdos to fsck.
However, if you use the recovery version of the Fix sd:ext this option, go directly to the recovery to select the repair on the line.

After repair, restart the phone, a2sd+ can be re-enabled, space is no longer insufficient, the lost program can be recovered.

In addition, the actions that are likely to cause this problem have the following points to note:
1. after the machine after the boot after the best shutdown and then open (no matter what you brush the package or patch, whether wipe), do not have this operation, easy to install software to cause system restart, ext partition error

2. do not be superstitious to restart the software of various types of rapid restart function, to complete the installation of the software and other data, it is best to use the shutdown option, rather than rapid restart, only know what to do in the case of the use of rapid restart is a good habit

3. When you need to remove the memory card, patiently waiting for the system to shut down normally, do not rush to unplug the battery, after the black screen is still waiting for about 5-8 seconds, although the black screen, but this time the shutdown action has not been finalized, trade rashly unplug the battery easily caused by ext damage.

The Nand backup is similar to a system backup and Bart is like a ghost backup on the PC.
Nand Backup It does not back up the ext partition (that is, the second partition does not have partitions can ignore this)
So if you APP2SD, then the program in the second partition is not available with NAND recovery.
BAR T can be backed up to ext partition with Bart recovery you can restore the entire system so that it's exactly the same as you did before you backed up. There will be no loss of file information (including contacts, text messages, pictures, audio and video, etc.), so if you have more stuff, then backup and restore will be slow.
