You'll wanna check out the EFS Backup solution here: http://forum.xda-developers.com/showthread.php?t=2514095
or TWRP offers an EFS backup as well. Not sure of other recoveries and TWRP does everything I need it to do, and well.
But if it is already corrupted...yikes. I haven't seen any tools to fix that on the Nexus 5. Remember some in the Samsung forums, but not helpful here...
Some people had success with just fastboot flashing the stock cache.img file, though depends on what borked it in the first place.

I read in one of the threads that if your IMEI is good (mine is, have yet to flash a ROM), that you could simply copy the EFS Directory from your phone to the SD card, etc. I copied the entire EFS folder to the internal SD card and also to my PC. Two questions:
1. Is this all I will need in the event I somehow lose my IMEI
2. When I look in the IMEI folder inside the EFS folder it is only 3 bytes, doe that really contain the IMEI
3. (ok, I lied about the 2 questions) I read someplace that if my bootloader is unlocked (which it is), I didn't have to worry about losing the IMEI?
Thanks
This is the way to backup IMEI. http://forum.xda-developers.com/showthread.php?t=1852255
Unlocked or not, you can still lose IMEI on any reboot.

Is this the best way to back up now? I remember that there was once a method using dd. But it's didn't always restore correctly right? Are there any other methods?

This is the standard way to backup your IMEI. The old method is not as comprehensive, read the OP of the method that you quoted and you will see why this way is more complete.

MD5 sum mismatch? Then either your backup is corrupted or you changed versions of Clockworkmod Recovery in between backing up and restoring. What version are you using?

Did you rename the backup by chance to something with spaces in it and unapproved characters? Backups can't have any spaces and must use A-Z, 0-9, and underscores in the filename.

There were a lot of issues with CWM recovery v6 prior to 6.0.1.0. One of them being backups getting corrupt. There's good chances your backup is corrupt and you'll have to start fresh. You can try installing 6.0.1.0 and see if you're able to restore (although I would doubt) or you can try to restore partially (Go in Advanced Restore).
Either way, make sure to upgrade to the latest version once you are done.
One more thing, have you touched the Clockworkmod folder in any way? Touched the blobs folder? Freed space? Because the way the new Clockworkmod works is incremental, so you don't want to modify anything.
No i didn't tamper with dat folder. Pls can u point me to where i can download the version u are talking about?

Rightmost column.
Personally I do not like the new CWM v6, so I'm using version 5.8.0.2 Touch. Very reliable, but the backups are larger than the new one (but complete instead of incremental)

you can get into cwm from rom manager, if you dont know how to get into cwm since your device is a Galaxy s2 t-mobile, turn it off, hold power up and power button at same time untill you see the samsung logo.
A similar problem occurred with my Samsung Galaxy GT1900. The efs folder was corrupted and I was unable to fix that. Factory restore, rooting and installing a new ROM also didnt helped. There were few guides here to fix it by ourselves with some tweaking. But none worked.
The only way i made it work is that by buying a gadget called J-tang or just J tang.
By connecting J tang to PC and mobile to J Tang it manually pushes a new efs folder. But by this yout IMEI number will be changed and you will get a new IMEI number which will restore the mobile to working condition. That's how I fixed it.

Ok, I'm going to use the second method. (Second post of the thread "how to flash the factory image"in the sticky roll-up)
Just a question: flashing the factory image will delete my nandroid backup, right?
If yes, I can save a copy of the backup in my pc and paste it in the device after flashing the factory image and restore it?
Sent from my Nexus 5 using XDA Free mobile app
The factory reset would also have deleted your nandroid if you'd done it from stock recovery like the thread says.
Sent from my Nexus 5 using Tapatalk
In fact I see this after the factory reset with TWRP, anyway I can do what I said in the last post?
To flash the recovery stock I simply use the command fastboot flash like I was flashing the factory images or I have to do anything else?

Flashing the factory image will wipe your device if you use the flash-all bat. Copy your nandroid to your pc. You can copy it back after you re-flash install your recovery

In the "TWRP" folder in the Nexus now I have to put only the "BACKUPS" folder or "BACKUPS" and ".twrps"?

You'll need to put the nandroid backup file in twrp/backups/your device serial number/

Hello!
Was wondering if I'd get new notifications when restoring from a Nandroid backup.
Hi, thank you for using XDA Assist. I'm not sure what you notifications you're talking about? A nandroid will restore you device to the same condition your phone was in when you made the backup. It's like restoring an image on your pc.

Well.. General new notifications. Say for example, a text message on Whatsapp. Do you know if that would appear in my notifications or in the app when I restore?
If you got them before, you'll get them again. A nandroid is nothing more than an image of your system the exact same way it was when you made the nandroid.
