Hi,
I hope someone can answer this question:
I dropped my Oneplus 7pro and the screen cracked. Its still useable but i bought the same model again and want to use the backup of the old phone. I took a full backup from the old phone and now i am not sure if should use the whole backup or f.e. only the system and data image?
Anyone didi this before?
Thx in advance
Edit: Twrp on the new phone didnt even recognize the Backup file from the old one, so I am doing it with Oneplus switch app.
System and data may work. But nothing else. You'll end up with a messed up efs if you do

hello, latly i installed a custom recovery, and flashed a preview cm7 rom for my lg vortex. while i was playing around with it, my nandroid backup got deleted off the sdcard. i tried to get it back using A LOT of various recovery software, but i had no luck. so now i am wondering if someone with an lg vortex is willing to share their nandroid backup, or can someone help me recover it!? and i also need the stock recovery .img, cuz i forgot to back that up before installing the custom recovery! Thanks in advance to anyone who can help!
If i were you i would not get someone else's nandroid. The reason being that a nandroid backs up EVERYTHING, including phone radio data and and the phones unique network signatures. If you fashion a backup from another phone the software will work, but i dont believe you will be able to make calls or have any network connection.
I know this because my buddy with an evo flashed a backup he had from his original phone into a replacement, and really screwed things up...
You may just have to flash stock software by other means, and each manufacturer has a way to do this. Check the forums for the vortex and there should be a solution.
Thanks for the heads up on that! and what about the original recovery.img? is it possible for someone to give it to me, or is everyone's recovery unique also?
Hello,
I started with Galaxy Note 2- i317M (rogers, canada), rooted with DN3 V4 beta installed. But I wanted to try DN4, so I created a back-up using TWRP and tried installing DN4. However, I later realized that it is not for the LTE versions yet and phone did not recognize SIM anymore. So I wiped the data and tried installing dn3 v5.5, but the phone still did not connect.
Losing all hope I installed DNv4 again, but it still did not work. So i finally just tried restoring from the back-up I made using TWRP. Everything in the phone is same except no network.
Finally I tried restoring from back-up after doing a complete wipe of internal storage and everything except the external card. But still the error does not go away. I researched more about the error and the fact that my imei shows up as null/null. I used the instructions of using EFS professional, but it did not work. The model number in my phone now shows up as SM-G900F and baseband shows as unknown, and it shows DN3V5 Rom despite the clean-up and restoring from DN3V4.
Any guidance available on this please...I need specific steps because after 12 hour search and try-outs I am lost now.....
UPDATE:
Solved it! Here is the solution for anyone in this problem

worked like a charm.. No reason to throw this and get a new phone
I have had this problem. It didn't happen whilst flashing though. My imei number is now a generic one and I had no efs backup. After 5 days of trying everything I can find I'm giving up. My note 2 is dead as far as I'm concerned. As far as I'm aware to get my imei back I'll have to send it for repair so I'll buy another phone and not a Samsung
I don`t think your phones are dead. I didn`t try it personally, but I`m sure you can restore your EFS back. Just you need to do some research, maybe you could start here:

Do not give up, read on end you will eventually do it! And, by the way, next time maybe you don`t forget to back up before doing anything to your phone!

I did back up. with both titanium backup and twrp but it is not working. And I dont think I will give up. I will format is all together and start over if i have to.
Do you think it will work if I format it entirely and start over?

Hey all,
I restored a backup of my old phone made in TWRP – a full backup, including Boot, System, Data, Cache & EFS – onto a new D850 I got. Both the old phone and the new one were able to connect to AT&T before this.
Now the new phone, with the restored backup from the old one, displays a network searching icon indefinitely upon reboot.
Any thoughts as to how to fix this?

Why did you restore a EFS back from your old phone to your new one? Unless you backed up the EFS from your new phone there may not be a way to fix this. EFS Is different for each phone you should never restore an EFS from a different device.

My *guess* is that I should not have overwritten the new phone's EFS with the old phone's? I think I backed up the EFS of the new phone before doing so; will restoring it fix my issue? If not, how screwed am I?

See if you have a backup of the new phones EFS try that and report back. If not it's pretty much a WiFi only device.

I restored the new phone's original EFS, and all is well.
FWIW, my reasoning behind flashing everything from the old phone to the new was that is what it said to do in every guide I read about transferring from old to new. I didn't realize EFS was supposed to be excluded; I didn't realize the EFS from one phone would be incompatible with another
In any case, crisis averted – thanks for the confirmations along the way

It's not that the EFS is not compatible. But the EFS stores info like IMEI etc. you can't have two phones with the same imei. Each EFS is different. When restoring you don't have to restore every thing though. I'm glad you had a backup! As without that it pretty much would had been an wifi only device. Your very welcome .

Hey guys,
It's briefin here. So yeah long story short, I recently restored a TWRP backup file of the EFS partition from another OnePlus 7 Pro. Now everything else seems fine but unfortunately my whole IMEI is just messed up (It's showing 0(zero). And that's why phone 's network signals isn't working anymore. Also I don't have any backup of my original EFS Partition. So is there any way, that I can rewrite my IMEI to my device?

Buddy I'm kind of in the same boat. I tried a sim unlock I was directed to and lss my backup became corrupted and gone forever. It's been a nightmare. And so far not looking any better or at least for me. But if theirs a way I'll find it

Thanks. Mine wasn't a imei issue. I actually fixed mine found a 2nd copy of my efs backup I drunkenly made
Is there a way to perform a nandroid or similar complete backup without a custom recovery like TWRP (which there is none for Android 11 or the Oneplus 8T right now).
I know I could use DD to dump and restore all the partitions, but I am unsure if this would work for the data partition cause it is encrypted. Cause I think the encryption keys are stored in the trustzone and can't be backuped or restored?
Do anyone know of a solution? Would be nice to have a good working backup to fall back to in case I break something when I start modifying the device more.

Hello Qnorsten,
I´m new to OnePlus devices (using a 8T model) and searched also for a backup method just to be shure that I can restore my data after a soft brick throgh a bad magisk mod.
On OnePlus 6T forum I found the magisk module ´migrator´ which can be used for backup and restore data and system data. I will test it the next days if it works for me.
Do you know more about migrator? https://github.com/VR-25/migrator
