Just like repairing FAT partition, this can be done through fsck, just run the command to change from fsck_msdos to fsck.
However, if the recovery version you are using has the option of fix SD:ext, just go to recovery and select repair.
After repairing, restart the phone, a2sd+ can be re-enabled. The space is no longer insufficient, and the lost programs can be retrieved.
In addition, there are several things that are easy to cause this problem to be paid attention to:
After flashing, it is best to turn off the power and then turn on it (regardless of what package or patch you have brushed or whether it is Wipe). Without this operation, it is easy to cause the system to restart when installing the software and make an error in the ext partition.
When you need to remove the memory card, wait patiently for the system to shut down normally. Don’t rush to pull out the battery and unplug it. After the black screen, it will still wait for about 5-8 seconds. Although the screen is black, the shutdown action has not been completed at this time. Removing the battery rashly can easily cause ext damage.
Recovery Project Model Chinese and English Comparison Table Detailed Description
1、Reboot system now——Restart
2、USB-MS toggle - Connect USB directly in recovery mode without exiting this mode
3、Backup/Restore – Backup and Restore
3-1. Nand backup—Nand backup
3-2. Nand + ext backup—Nand backup (the system and ext partition are backed up together)
3-3. Nand restore - restore (that is, restore the last backup of 3-1 and 3-2)
3-4. BART backup—BART backup (including system and ext partition)
3-5. BART restore-restore the last BART backup
Nand backup is similar to system backup, while BART is like ghost backup on PC.
Nand backup It will not back up the ext partition (that is, the second partition. If you don’t have a partition, you can ignore this)
So if your app2sd is available, then it is impossible to restore the program installed in the second partition with Nand
BAR T can be backed up to the ext partition. Recovering with BART can be restored to the entire system. It can make it exactly the same as before you backup, and there will be no loss of file information (including contacts, text messages, pictures, audio and video, etc., so if you install more things, the backup and recovery will be slower)
