Hopefully you had a backup. Just restore it.

I went to the last nandroid I did from 8/10 and its not there.

go through your nandroid backups, and find one with the rsa keys. once you find the rsa keys, back it up on that rom and reflash your current rom.

You can actually remove all of the ".img" files except for the WiMax.img file from any backup folder and then restore that backup, making it only restore the WiMax key and not whatever ROM you backed up.

Unless there's some method I don't know about, yes. Hopefully you're still in your first year with it. Tell them 4G doesn't work (and unroot it of course). You'll have to bring it to a Sprint store.

Nandroid Backup Location

I'm looking to delete some of my old nandroid backups that I won't use, however I can't seem to locate them on my SD card, anyone know where I can find these backups at for purging? Thanks!
Edit: clockwork puts backups in /sdcard/clockwork/backup/<date> other recovery imgs put it in the nandroid folder on sdcard root.
Should have searched first. However I do have a follow up question,
what does the last set of numbers after the date mean,
2010-08-05.01.42.54
01.42.54? I'm not following the reasoning, thanks!
Yup. Here's my question. How do you APPLY one of your nand backups, since it's not a zip file that recovery will find. Thanks in advance.

Instead of installing from zip card, go into nandroid>restore and that should give you the choce of backups to restore to.
Eeeeek, those numbers represent the time that you made the backup.
Scott, in Rom Manager you can choose restore and find the folder you want to revert to
Hairongreenfire, thanks. I'm guessing the same is possible thru amonRA recovery? (I trust that recovery more than clockwork)
Thanks.

Rename?
If the backup files are renamed can this cause any problems with the restore process?
I use AmonRA Recovery

If you rename them don't add spaces: so mikg-311-03-29-12 is OK but mik g 3.11 03-29-12 will result in md5 sum mismatch

First this is not the forum for questions. The question and answer thread is better suited. That said I wouldn't recommend restoring a backup from another Rom , especially if you used amon

Ya if you overwrite your wimax code from the previous phone it could mess up your 4g. Just suck it up and do a clean install on the new phone.

Exactly, if you flash over your wimax image it WILL bork 4g. (I haven't tested but it only makes sense) The idea of backing up wimax is to keep keys in tact. If you flash keys from another phone, then you my friend will be on evo #3. haha

I agree 100% with everything said here, just use your other Evo as a template for which programs to download and such and do not use Nandroid to restore stuff from your older Evo. If you write over your WIMAX, bye bye 4G. That or you can only use 4G on one phone at a time because they will share the same key.
You were already told that this is the wrong section, so no need to repeat. Please post in Q&A next time if you have questions, saves a MOD from having to move your post.
isn't there a workaround?
Could you just remove the wimax.img from the nandroid restore folder and then restore the other img portions? (Unless of course the restore process must have ALL the img files to complete)
Or maybe move all your img files, except the wimax one, into a PC36img.zip and restore via bootloader? (unless you have to sign the pc36img.zip file somehow)
I suppose removing all the radio images would be prudent here. You're really just interested in /boot, /data and /system I believe.

[Q] TWRP Backup Transfer

So my phone broke and I got sent a new one from Sprint, and I had all my TWRP backups on the external sd card. I have TWRP now on the new phone, but it won't read the backups from the external sd card and when I moved the backups into the TWRP folder on the internal sd, it still won't find it in recovery. How can I get it to read and restore a nandroid from the other phone? Any help is really appreciated
Are you sure the backups weren't made in an older, not compatible version of twrp?

Yes, they were made with v2.3.1.0 and that's the version I'm also currently using, only thing I can think of was that originally I got TWRP from Goo.im app and I installed it via Odin this time.

They're not corrupted at all? No backups named with invalid characters, like spaces?

Not corrupted, but they do all have spaces and dashes... I'll try removing them and seeing if that does it

if you run a nandroid backup on the new phone, compare the numbers for that backup with the numbers for the old backup you want to restore. they will be different numbers. i had this issue before and changing the numbers from the old backup to the same numbers of the new backup fixed the problem. then TWRP will see the nandroid for you to restore. the folder inside "TWRP" then the folder inside "BACKUPS" that is the folder you want to rename. it will be a number like.....mine is 9202f5d1. thats the number specific to that exact phone. good luck.

Lol, that's what happens when I assume. Though yes, that's how you restore backups between phones. Also you'd have to do this on any recovery, should you ever switch recoveries and need to transfer between phones. Though I wouldn't restore the system, personally.

[Q] Nandroid backup size

I just made a backup via nandroid and CWM of my phone in possible anticipation of trying out a new rom. However, the backup is only 21mb. How is that possible? Does it not back up my apps? What exactly gets backed up?
Thanks!

It should backup everything. I would suggest remaking a backup.

still only 21mb.
CWM backups show as very small on the inital folder but I believe if you drill down further all the information is stored in what is called a blob IIRC and that will be larger folder.
I would suggest TWRP instead as it is easier to store your backups in a safe place just in case you have a srcew up.

Check to see of you also have a folder in the cwm folder called blobs. Your info would be there and it should be a considerable size.
Sent from my SGH-I747 using xda app-developers app
This probably could be different depending on which version of cwm you have installed so take a look first.
Go I to recovery, choose backup and restore, scroll down to CHOOSE BACKUP FORMAT, then you will see .DUP or .tar
What you have right now that saves them as blobs is the .DUP format and has a separate folder that your looking at. If you change it to .tar format it saves the whole nandroid backup in one file.

Efs folder backup?

Hi, I stupidly went back to stock and lost my imei number without making a efs backup, when I used aroma it asked if I wanted to make an efs backup and I said yes.
Would that backup help me in returning fully to stock rom? If so, where would that backup be stored in my phone?
Hope someone can help
Thanks a lot

I must add that I didnt back up on the stock rom, I was already on a custom rom, if that helps.

The backup you made will be no good cause it will contain the efs of the new rom you installed.. you can check though. The efs backup will be on your sd card..
Sdcard/EFS
In efs theres folders inc imei wifi bluetooth etc
Sent from my GT-N7105 using xda premium
Do I have to be rooted to see that folder? As its not in my sd card, the only way I can see that folder is in root explorer but im not rooted at the moment.
Can I ask one more question? If I were to put stock rom back on my phone and use newer modem, my imei and network will come back, would I be able to get ota updates? Because when ive tried to search for an update, it would just hang on searching.

Ive had a look in the efs folder and all I have is a list of files which include nv.data.bak and nv data.bak md5? Is tjat any help? Would I need those files to restore

Yes. Copy them to your pc under efs backup aswell for safe keeping. There are guides on here of how to restore your efs with 4.1.2 roms but you will need root.
As you have efs backup I found this for you. Make sure you read and understand before doing anything..

That zip file in the link is a app. Download install.. if you backed up the efs on the stock rom before flashing the new rom it will work..
The only other thing to do is flash this modem via cwm recovery.
It says it fixes the problem

You've backed up the new modified efs folder which is only compatible with the new firmwares. You can restore from that backup, in fact you need to, but there is no going back to old firmware now. You can achieve stock if you download and flash a stock rom of version DME6 or newer, but you can never use anything older again.

How would I go about restoring that backup from efs pro? As when I am trying to select it in the restore section of efs pro it can not be seen in drop down box?
It is in tar format, there is a pit file with it but I guess as I wiped everything out of my actual efs folder through root explorer it might not work.
Also I have a pop up on my screen with loads of different information like an error pop up? I cant screen shot it other wise I would show u
