I made a complete back up using twrp in my device but while restoring reaching 53% it is automatically switching off. But this only happening while restoration of backup, not taking place while flashing custom ROM
Please help me with a solution

Try to watch on what file it is switching off, then delete it from backup and try to restore again.

Untick System Image (not system) in TWRP menu

[Q] Nandroids

What exactly does a Nandroid backup. Is it like creating a Hard Drive image for windows?
After installing CM9RC I want to go back to my previous stock configuration. If I restore my phone with a nandroid, will I recover everything previously installed on my phone? I am assuming the stuff in the sdcard folder gets excluded from the wipe right?
Thanks in advanced,
Aphis
Yup a Nandroid is more or less like a restore point. And yes excluding sdcard.

Yes. Note that a nandroid backups up the system partition, the boot partition, the recovery partition and the userdata partition (excl. /sdcard). It does not back up your radio or bootloader, so if you change those, you will have to flash them separately.

Yes!
EDIT: Ninja'd by WiredPirate.
Thanks for the quick response.
That would mean that if before creating the nandroid I had permanently installed CWM and rooted the phone, restoring the nandroid would keep my phone with CWM and root right?

its a snapshot. whatever you had at that moment when it was created is what you will have when you restore to it.

No, I meant I hope you made a nandroid backup before deleting those system files. If you did make it, do a restore and everything should be back to normal.

ah no i didn't :crying: can you give me an 3.20.401.1 ruu ?

there is no 3.20 ruu and a nandroid backup does not restore the imei otherwise we could not change to other backups (from other people like in the nandroid backup thread) your problem is a bit more serious. Because how do we restore a imei everytime after a full wipe and custom rom ? The parts you talk about are not stored in a rom or a backup !
just flash a stockish rom like ARHD with a full wipe (and flash the boot.img via fastboot) and see if that helps !

It depends on a lot of factors.
What ROM, what TWRP version, what partitions did you back up, etc.
If you want to get your phone working, you can flash any ROM of your choice from TWRP or restore stock image.

TWRP Version is the last one (I think). I backup every partition so I made a full backup of everything. The rom Is the simple aosp. I very want back all my stuff

Backing up all the partitions was the mistake.
Getting your stuff back looks difficult.
If you flash ROM using TWRP, your media files and anything stored on your phone won't be deleted.
But all your apps and stuff will be lost.

Yes it can be backup,
It is recommended to backup every partition and keep a copy of whole twrp backup folder in PC so that if something goes wrong u can restore them later.
Many times peoples lost networks,phone lags,low battery backup,no sound in call or many other problems so be on safe side, backup your device.
