[Q] Error Restoring Data from TWRP backup

Hi All,
Ran in to a bit of a problem when trying to restore a backup i had made in TWRP 2.4.3.0.
The System restored, but the data, which is 700MB took around 2 seconds to "restore", and just wiped the Data partition, instead of restoring anything.
If anyone knows how to overcome this issue i would be much appreciated, as I was trying to recover everything in Data.

This is common in the last few versions of TWRP. You can try using Orange Backup in the play store to restore it.
Thanks for the reply.
Managed to restore all my Apps and Data from Titanium Backup, which is a lifesaver!

[Q&A] Restore EFS from Nandroid Failed (Solved)

Hi Everybody,
I'm really disappointed. For the second Times, I've corrupted my EFS partition. IMEI is empty, as the baseband...
The first time that I had this problem, I could restore the EFS using the fabulous fix from Fireasusman : http://forum.xda-developers.com/showthread.php?p=47014662#post47014662
But this time, It didn't work.... I'm really really sad.
Before trying to restore the stock firmware ( My problem was coming when i tried to restore stock firmware before to sell it) i made a Nandroid backup with TWRP recovery. I've an EFS/MODEM backup in this Nandroid.
When I reboot into recovery, and go to restore, I can select EFS, and it seems restore It. It wrote : Restoring 2 partitions/Restoring EFS/restoring EFS2/restoring EFS3/EFS Done/Restoring Modem/ Modem Done...
But after reboot the problem is Still There...
I'm really Angry, I lost 400$ and I don't understand why my Nandroid Restore of EFS failed...
I also try to flash modem with ODIN but it still Failed.
Note: I was an temasek CM12 (android lollipop).
Thank you very much for every help.
1. Flash STOCK ROM and take a look how it works. Sometimes only flashing it recovers the EFS folder.
2. Next time use this APP for backup/restore your EFS.
Really thanks for your help.
But i've allready try to restore stock ROM. At least twice. But efs is still corrupt. And the phone never arrive to boot...
About how many time I can consider that flash stock ROM will not repair my EFS partition ?
I've allready done twice...
Ok... I solved my problem.
As I explain in first post, I'had a EFS backup with a Nandroid Backup. But when I restore with TWRP, the problem was still there. No pin, No baseband etc...
I only delete the EFS folder using root explorer. I reboot, and it was OK. EFS folder was rebuilt automatically.... No more complicated than that...
Good finding

Because the IMEI is not stored in the EFS folder.

[Q] TWRP restore to a replacement device--what should I restore?

Ok, so I had to get a replacement Note 4 due to camera hardware issues. I made a TWRP backup of my original phone, now I want to restore things on my new phone. My question is what should I restore? The things I backed was everything I could:
Boot
Recovery
System
Data
Cache
EFS
Modem
Should I restore everything? I get the feeling that I shouldn't try to restore EFS for some reason, but I am not sure. Anything I definitely should not restore on the new device? Thanks

If your phone is rooted then you should have twrp installed
and if you have twrp installed it has an options of what it
can backup when you select "backup" or "restore" and
there you will see an option to only backup efs or backup
other things in the phone like system, data, cache & dalvik.
Select EFS and nothing else if that's all you want to backup.
Good luck, have a great day!
Thanks alot dear.. I already did that in twrp. Is that the only thing which I need related to efs ? Is twrp efs backup is reliable ?
Yep.
But move a copy of the backup to your pc just in case you have any future problems.

Restoring with Nandroid

I have a twrp backup with all of the partitions backed up. I came from an S5, and when I would brick it or something, I would just boot into twrp and restore from the nandroid I previously made. But, now with the Oneplus 5, when I go to restore with a nandroid, it doesn't let me restore the data partition. I searched for solutions before posting this. The closest solution I found was to use titanium backup pro or similar app, to restore the data. Am I doing something or missing something? I thought when you made a nandroid backup it was just a copy of every aspect of your phone, which could be restored at any point?
You should have read the recovery thread. It says it can't restore OxygenOS data backups right now.
It actually says it will lead to a bootloop if you do. Maybe they disabled that option temporarily.
You can try this.
