So I had to do a TWRP recovery on my phone, but I used an old backup, that was previous to OnePlus replacing my main board. I know that you must never lose the EFS partition. Luckily I did make a new backup after the board replacement, so I had an EFS backup to save the day. Are there any other partitions that I should restore from the latest backup?

First off I'm at the final stage before I introduce a 'software error' onto this phone and return it to a sprint shop for a replacement.
I have a broken nandroid backup, that DID however backup my wimax partition.
Now, my wimax RSA keys got nuked somehow and I figure if there's a way for me to restore JUST the wimax.img file, I might be in with a chance of having a workable evo again.
The thing is, I can only find guides for restoring a full nandroid backup, and nothing for restoring wimax individually.
Would anyone be able to help?
Thanks.
welp, i answered my own question.
I just copied the nandroid backup .img to wimax.img in my root directory and everything works fine now
Remember boys and girls - BACKUP FIRST. Thank-me
I might be wrong, but you should be able to make a new backup, and just copy the WiMax partition over. If your keys got nuked though, it might throw off the checksum of the backup, which I don't know how to change. And again, thats mostly theory, I'm no Dev.
Do a new nandroid backup, reboot, brows your SD card for nandroid, then there will be another folder, and inside that one will be the different backups. Open up the one with the working wimax partition, copy it, and put it in the nandroid you want to recover.
I would be sure to do yet another nandroid backup, just in case you mess something up.
Edit: Slow typing ftl, looks like you got it!
Hello everyone!
Yesterday, I tried to upgrade to a Kit Kat rom. I used the Galaxy nexus toolkit, and did a full backup... plus an EFS backup. Afterwards, I did the full format/wipe from CWM recovery, and installed the ROM.
Well, apparently one of the options wipes your EFS file folder; I have no way of connecting to my network. My IMEI is the stock number, and I've spent hours scouring the internet trying to find a way to restore it. The majority of the responses are "try a factory reset and restore" or "too bad so sad, should've backed up". Well, I did try several options. The first being the EFS restore. Apparently, the backup is stored on the phone and wasn't sent to my computer, like the rest of the normal backups. That option is now out. Oh, how I miss SD storage.
The second was a full restore to stock, again, nothing. Third, I had an old nandroid backup. After doing these I saw that the EFS tree is left untouched, as it is so delicate. The only way to do this is give up and send it in for servicing, or to do a phone NV Backup swap with QPST.
I need to get access to the service menu (or any way to change the USB/Modem) as listed here: http://forum.xda-developers.com/showthread.php?t=1946915
Unfortunately, *#7284# does nothing on an i9250, nor does anything besides *#*#4636#*#*... which isn't what I need. The terminal command doesn't appear to work, either.
I don't understand very well but, have you tried to restore your EFS backup from recovery? Did you make the backup from recovery or from toolkit?

I have done a recovery from the toolkit (as the files are stored on the computer and not the phone) which is where I made the backup from, as well.
However, the EFS partition is apparently never included in this backup, as it is supposed to be immune to changes and formatting. I proved them wrong.
Well I did that same blunder last month with my nexus and then I tried all remedies plus own experiments but couldn't get results. All I heard is that to send phone to service centre. If you find any other solution so do mention here, I gave up after so many tries

I have personally never used the nexus backup tool, but if it does does backup the /radio folder, you may be in luck.
Well, it has been repaired. Thank you all for your help, in the end I managed to pull some things together in a mash up of fixes.
It appears that upon a new restore from a nandroid backup, I was still getting no signal. However, I did a *#06#, and my IMEI was intact. I read that the Radio folder gets backed up, but not the factory folder. Upon a new install, I imagine the radio folder is wiped, which is why every install from then on had a bunk imei (it had nothing to pull from as my factory folder is toast)
However, it looks like the efs backup I had *did* save the folder structure... I found the efs.tar backup in my galaxy nexus toolkit folder. It had the folder zip, but couldn't restore it due to permissions... didn't feel like messing with that at the moment. I copied them in with root explorer, grabbed the nv_data files from the /radio/ folder, deleted the files from /radio, and restarted. Lo and behold, they were restored from the factory folder with the correct IMEI.
I just put a fresh copy of kit kat 4.4.2 on and have cell service again. Oh happy day, I don't have to use my old HTC Sensation! :highfive:
This also marks the first time a backup actually saved my skin. Usually I vaporize the backup accidentally before it has an opportunity to prove itself useful.
Hello XDA, I am on the process of moving from stock 4.2.2 on my DUOS to a Custom ROM, I haeve my device currently ROOTED, with CWM, SU app, ROM has been backed up using CWM/ROM Manager, Stuff synced with Google, Apps backed up with Titanium, need to be sure I have a recoverable EFS backup.
Now here is where I halted the process because I have been reading quite a lot and talking to people used to flash their phones but none of them have a GT-I9082 and we aren't sure that about what partitions are vital for an EFS restore.
I know I have backed up using EFS Professional my EFS partition but other than that no other partition was available (Used International Variants option as filter, since my device isn't listed by default). I added manually a filter named ftaer my device, the way I made it was reading the PIT file and selecting all the available partitions, but I'm still not sure whether that would suffice to recover a broken EFS.
I would really appreciate any input from people who already recovered their EFS successfully either using EFS Professional or any other method, please tell me which partitions have you backed up.
Is there any app or recovery procedure that can back up your entire device then restore it exactly as it was in the last backup you made? Acronis for Windows had the ability to do complete system backups then when you restored it would delete your partition and overwrite it with your backup. I'd like to see something like this for android on my Redmi Note 5 phone.
I am interested in this too.
I think this is only possible through recovery. TWRP does that.

I used TWRP on my old Nexus 7 2nd edition and it use to leave apps and data files behind that were installed after I had made a backup but maybe I just didn't have the right settings or do the correct procedure
Nandroid backup through TWRP recovery + manually backup your entire sdcard0 folder (TWRP backups everything except for internal storage)
This way you have a 100% backup of your phone
Old phones input mic is broken, getting a new one. Both are 16gb ones, backed up everything with Titanium and created a nandroid backup, then copied everything from the storage to a USB stick.
I know it's not as simple as installing TWRP on the new phone and restoring it because the serial is different, but is there any way to modify the old backup so it can restore on the new phone? For example if I create a nandroid backup on the new phone and copy certain files/dirs from the old phones backup to the new one, will the restore work? Or am I just gonna have to unlock / root / install new factory images / rom / gapps / kernel blabla from scratch and then restore with titanium backup and copy the storage folder over?
Thanks in advance.
