We now have a custom recovery, and it is only a matter of time until we also have custom Rom. :good:
How can I backup my EFS and Imei ?
On my Note 2 that was easy.
In addition, I always read about NVRam backup with QPST.
I really have no idea.
No setting for that in current TWRP Recovery?
Yes in TWRP I've already made a EFS-Backup.
Is a 14.97 MB file.
Is there really anything important in the file ?
I often read about QPST and Backup NVRam in S5 thread. Or is that not important for the S5 mini.
No more needed. Save it on a save place. With thst backup you can restore broken imei...
I use EFS Professional, is very good.
P.S: Need root and busybox

Hey all,
Are nandroid restores specific to one particular device or can they be interchanged between two G1's? I have a spare G1 that I play around with that has root while my other G1 doesn't have root. I am thinking about rooting the other one and wanted to know if I could just go through the rooting process, (radio, spl, cyanogen recovery etc) throw on a cyanogenmod or JF, then do a nandroid restore from the spare device with all my settings on it. I know that nandroid creates a unique numerical folder that has your latest backup in it so I wasn't sure if this folder would be seen by nandroid on a different phone.
Any thoughts?
EDIT:
Just wanted to update this thread in case anyone else wanted/needed to do this. As I suspected, I ran into folder name problems when trying to copy one nandroid restore to my spare phone and trying a restore. There is a simple fix however....
1) Perform a nandroid backup on the phone you WANT to backup.
2) Copy that nandroid folder from the phone to your PC.
3) Perform a nandroid backup on the phone you DON'T WANT to backup.
4) Copy that nandroid folder from the phone to your PC.
5) Compare the nandroid subfolder name (should be alpha-numeric starting with HT) of the backup you want to the name of the one you don't.
6) Change the name of the nandroid subfolder on the backup you want to restore to the same name of the folder you don't want. This way you fool nandroid into thinking that the backup was originally done on that phone.
7) Copy the entire nandroid folder (with the newly changed subfolder name) to the sdcard of the phone you want to restore.
8) Boot into recovery (power+home) and perform the nandroid restore. If the restore fails, you probably don't have the correct subfolder name. Return to step 5 and 6.
9) If the restore is successful, reboot and you should be all set!
Good question. I wouldn't have thought there would be issues with it bar of course your settings etc but then a wipe before would resolve that. Just make sure to do what you've said though (upgrade radio, SPL, recovery etc) first.

It won't upgrade your SPL, radio, and recovery. If you look in the nandroid folder, you'll see exactly what is backed up. I think its the /system folder and the /data folder as well as something else. But if you have another phone that is already rooted and has the correct SPL, radio, and recovery, this will work.
Should be fine then as he's planning on doing the usual steps up until flashing the desired ROM of choice. Tell us how it goes DirectMatrix and if it works, please change your thread title to include [SOLVED] so we all know ^_^

Gonna start rooting the other phone now so I'll keep this thread updated with whether nandroid backups are swappable between phones. I hope so as that will save me quite a bit of settings/data calibrations.
@h.nocturna... LOL, you have been dealing with n00bs too long in the Q&A section....of course nandroid won't upgrade my radio, SPL, and recovery, but I had a good laugh anyways. Thanks all for the advice
Hey, I got some problems. Posted in another forum, but it's very urgent so I post it here to. Just quoting what I previously posted.
Hey, flashed the JVS modem on top of the Chameleon Final. Didn't get any signal and the baseband version in settings stated "unknown". Tried another modem, JVO and flashed back to Chameleon modem, still not fixed. Also tried to wipe everything and install rom again... did not help either. Odin didn't report any errors whatsoever.
Desperate for some help her guys!

Got reply that my IMEI was screwed, and replied:
[quote author=bahafeld link=topic=1931.msg13081#msg13081 date=1316107492]
Okey, I have backup of my original EFS folder. Isn't it there the IMEI is saved? can I just copy it over again with Root Explorer?
Please help me out here. All the guides I've found have the EFS saved in a .tar format. However I just backed up the EFS folder with root explorer. Anyone know I can recover my EFS, tried just copying it back, but that did not work.
Its kinda urgent!

So I hope you guys at XDA can help me a bit faster.
Thx

if you have a .tar version of your EFS. Unzip it. Copy all the contents of it, And paste them to the /EFS on the phone. Making sure they overwrite the current contents.
Once that has done, Restart the phone without backing out of root explorer (or what ever app you are using to copy/paste these files).
If that fails, Repeat the above step but ONLY copy / paste the NV_data.bin & NV_data.bin.md5
And finally if that fails. Backup all your stuff using Titanium Backup (or similar) And re flash a stock Froyo ROM. Maybe older, its upto you.
That will Definitely restore the IMEI, Then re-root and go back to whatever ROM you wish.
Good luck.
Hi everyone
I will try to explain my doubt.
I had a samsung galaxy S2 and when I tried to ROOT it and all that, the device ask me to do an EFS partition backup. Very similar stuff happens with Sony Xperia Z but in this case, I had to make a TA partition backup and then, make a system restore to drive the device to the default values (just the same values as when I bouhgt it)
So my question is, regarding to the mobile HTC ONE:
Can I make a XXXX folder (i mean, ANY folder) backup so that when I get the default values I can RECOVER that folder?
I have read a lot about HTC ONE but I don’t remember anything about this mentioned backups.
Thank you in advance!
Greetings.
Are there any verified ways of backing up our EFS? I couldn't see a confirmation over on the thread from the other forum:
http://forum.xda-developers.com/showthread.php?t=2447342
Or even a safe way of nvbackup would be great. :good:
Hi guys,
Yesterday I updated my cyanogenmod 11 with newest version doing a wipe cache first. After rebooting my phone seems to have an issue: the IMEI is null and I can't call or receive calls.
So I decided to flash the stock rom with odin, I thought that this could help, but nothing to do, the IMEI is still null and I can't use the phone
The first time I installed cyanogen I made a backup (using TWRP function), looking for that backup files, I discovered a file called efs.ext4.win, but if I try to open it with an unrar program, I see these files inside:
\.files
\bluetooth
\FactoryApp
\imei
\RFHAL
\RFHAL.DEF
\wifi
GUARDFIL
gyro_cal_data
pre_recovery.log
I don't see any "nv_data.bin" file or something like that. Is that normal?
Anyway, I think that EFS folder is corrupt or missing, i don't know. Is there a way to solve this issue? Thank you.

S3 mini has no nv_data.bin file in EFS folder. You made already a backup of your efs, try to restore it with TWRP to get your IMEI back

Thanks for replying.
I tried to restore EFS folder using TWRP and my backup, but nothing changed, I still don't have Imei and baseband.
Do you think that flashing a PIT file could help me?
Thank you so much.
