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

Specifically post #6 AND #9
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.

hi, i used clockworkmod for a while now backed-up, but never really tried to restore from those back-ups....
i just tried to restore a nandroid backup, i went on the PC and re-named backup as something i`d remember put it back on the Desire, and nandroid just fails instantly at `MD5 mismatch`
could this be because the folder name changes after the backup has been made??, thanks.
also i thought i was being thorough by doing a wipe, from nandroid 1st.
Luckily I went advanced `restore sys only`, this went back to basic stock, logged into myy acc on market, downloaded My Backup PRO, restored the apps/dATA i did with that app.
restarted phone, all is good
whats up with md5 missmatch ?
cheers
Don't move the file around next time. Probably induced an error.

not sure if its moving the file around so much, as the characters in the filename itself
i did a quick backup this morning, left the filename alone,restored it fine.
booted phone, went into Rom manager and renamed the original back-ups with that instead of PC, they now restore ok.
what i did notice though was when renaming from Rom manager it automaticly replaces spaces with _ seems a bit sensitve to certain characters.
must be filenames (or _+ - spaces etc)the are accepted ok on windows creates, arent freindly when nandriod comes to read them?
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!
I am running current version of Bonsai 3.0.1 Yesterday, my phone dropped and the battery fell out. When I tried to reboot the phone, there were many Force Closes. I tried fixing permissions twice but it was still having FC issues, so I figured I'd restore the data. Well, I hadn't backed up in several days, so I did a Nandroid backup before I went to restore. I kind of figured that restoring the phone from a backup of bad data wouldn't work and it didn't. Restoration from that backup causes a endless reboot. Sooooo, I restored from a backup which was several days old and it worked fine. But, my data is old for one particular app.
So my question is this: Can I extract data for one particular app and restore it from a Nandroid backup?
Or is it possible to restore the apps only from the Nandroid backup?
If I choose "Restore Data" from the Nandroid backup, I go into an endless reboot loop.
Restoring the "System" will bring the phone back to working, but the data is old.
Yeah, Yeah, I have Titanium and could have accomplished this easily with it, but I hadn't been backing up there either.
I know I'm probably screwed, but if anyone has any suggestions about how to get my data back (for one app or all), I'd sure appreciate it.

I think there is a way. Someone else had a similiar problem and wanted to get their text message data out. It is in the thread below where 00dwan talks about unyaffs and data files. Seems a bit complicated but if the data is that important you will need to be able to identify the data file for that app.

Hope this helps.

Thank you Thank you Thank you. Works great!
I'm having trouble putting the file where it needs to be (I'll figure it out), but I am able to get the information I need from the data file even if I can't get the file where it goes.
It is kinda weird. I put the file on my SD card and then put it into the phone. I copy the file to the clipboard and then go to the directory I need to place the file in. I select paste and it seems to paste the file, but nothing changes. I think it was because I hadn't mounted the system/data as RW. But the strange thing is that when I copy the file to the clipboard from the SD card, the file DISAPPEARS as if I cut it instead of copied it. Anyway, I'll figure it out.
Thanks again for the tip!

Glad it helped. Definitely sounds like it wasn't mounted r/w. Wierd that it disappears from card on a copy operation. Root Explorer is good for this.
I have an AT&T S3 which, during some shenanigans I don't remember, was encrypted with a password I could not retrieve. I used Odin to erase the phone's NAND because I had a nandroid backup. This backup, however, was corrupted. I was able to use Odin to flash a stock firmware, but I now only have access to EDGE instead of LTE.
I have restored EFS and NV backups from another AT&T S3 with my IMEI and serial written to them, and my serial and IMEI display correctly in my phone's status window.
I have tried flashing every available modem for the phone.
I have tried numerous APN settings and *#*#INFO*#*# settings.
I have tried damn near every solution to similar problems in this forum.
Any more ideas?
Where did you get your EFS and NV, and how did you restore them?

I used EFS Pro + Qualcomm tools to backup the EFS folder and NV data from a working AT&T S3. Doing this brought back my IMEI, but did not much else otherwise.
EDIT: To clarify, I used the tools to write my specific imei and serial to the backup before restoring that to my phone.
Ok, a lot of these usually don't get fixed, but I'm going to stick to here what worked for some.
First, I'm going to assume that you injected your IMEI correctly. I would next use the EFS Pro to format your EFS from the restore option at the top (then clicking format EFS), since that EFS came from another phone. Your EFS folder will automatically be re-created when you later reboot.
Next, I would download and unzip the attached file. Inject the .txt file with the nv reader /writer. The nv reader writer can be found in this thread.
http://forum.xda-developers.com/showpost.php?p=29514032&postcount=1
Follow steps 1-4, but instead of reading, you're writing the .txt file that you unzipped to your NV. It only contains missing information and should not touch your IMEI. Do not change the dec or hex range.
Reboot the phone and see what happens.
Hi,
I've had the same problem with my M7 and now my M8. I can do HTC backups no problem, but when the time comes to restore, it never works, it'll get to about 37% and stay there for hours until I reboot. Some stuff gets restored but not much.
I tried:
- Skipping the restore at first boot and restoring after - Same problem
- Skip the restore at first boot, kill all the apps, manual restore - Same problem
The sign-in to Google plus works, it does find the backup each time, it just stalls completely when I restore.
Titanium backup, if your rooted. Can't beat it. ?
Sorry for indirect solution... But I froze HTC backup on day one. ?

Yeah I also tried HTC Backup once and froze it, didn't want to properly restore for me either. I rather make backups of the entire data partition and just number it appropriately. For example: Made backup on 1 October, Place it in a folder named "Data October" next backup at 1 November in a folder named "Data November" <With that backup in the folder I make a text document with info of all additional programs/changes I made since last backup, in other words, a mini change log. Will make it easier to restore to a point prior to a point where I had an "incident" (Even though I never had one *touch wood* ). I use Titanium rarely if ever, used to do it a lot but I prefer backing up the entire data partition, as big as it is.

Yup, a good way to go! ?
I just prefer Tb. I have control over each app that way. But I have a Data nandroid also... Just in case. ?
