My micromax canvas nitro A311 is stuck in boot loop.I have tried to solve the boot loop problem but couldn't succeed.The only solution seems to me is to format my phone.I am able to go to the recovery mode.It shows the following options:-
- reboot system now
- apply update from ADB
- apply update from sdcard
- apply update from cache
- wipe data/factory reset
- wipe cache partition
- backup user data
- restore user data
When i select the "backup user data" option ,it shows "SD card did not have enough free space".It is reading my internal sdcard but not the external one.Is there any way I can back up data on an external sdcard or on my PC?My android phone is rooted.
