[Q]About EFS BACKUP AND RESTORE TOOL ON XDA

Hi I have a problem: i had a samsung galaxy s 9000. I had it for a year: i tried many roms on it ( cyanogenmod, miui, ecc ). I used ,also, a tool to backup my EFS's galaxy; this tool is here: http://forum.xda-developers.com/showthread.php?t=1138873
Now, I have a nexus s i9023 slcd. And here it is the problem: now, the linked tool to backup my EFS doesn't work. I root my nexus and the bootloader is unlocked. I used 5.0.2.0 CWM. The rom is 2.3.6 STOCK - GRK39F. I used windows 7 32 bit and I start the prompt command as Administrator. When I write "efs_backup.bat" I can read this:

Is it possible resolve these PERMISSION DENIED'S?
I ,also, type ( in the APP terminal emulator ) :
su
chmod 777 /efs
exit exit
but I don't solve the PERMESSION DENIED problem.
I hope you will help me.
I can't post in the "tool EFS backup and restore" thread (http://forum.xda-developers.com/showthread.php?t=1138873) because I'm new member

There's no reason why you can't copy the efs folder manually. Copy it into your sdcard and then copy it into your computer for an extra backup

I don't understand why the xda efs backup's tool doesn't work in my nexus s: it was ok on my galaxy s.
I post here to solve this problem: please, help me. Thanks.

I had trouble with that tool too. I remember i got it working, i think by moving the script into the sdk tools folder, and make sure USB debugging is selected.
Still, i don't think it is worth the trouble. You could just copy the folder like i suggested before, which is easier. Or you could install Team Win Recovery Project which can backup your efs

I read that TWRP recovery should create problems on efs folder during its backup/restore. Do you use it or cwm 5.0.2.0?

I use team win. No problems with efs when backup runs.
I haven't tried restore yet, but they assure it works.

[Q] Anyway that I can recover my phone???

Hello,
I have LG Optimus Elite Android 2.3.7...it was rooted...
I accidentally deleted /system/bin/sh...gee..oh my god..
The problem is that I am not even able to adb to my phone now..
If I do adb to that phone, it is complained about /system/bin/sh doesn't exist something...
Gee...........
Obviously, factory reset didn't help cuz it didn't restore the sh...
What would be my option ??
When I just reboot my phone, it is just stay "Welcome to" screen...Even though I touched the begin, it won't go next..I think because..
my /system/bin/sh file is deleted..so my phone can't execute anything from the phone shell..
What would be my option to recover my phone?
Please help
Thanks,

Get a copy of sh and
> adb push sh /system/bin/
But /system is read-only so you need to mount read-write. But you cannot because
> adb shell
Cannot execute sh because it is not there.
You need to restore from nandroid backup. Failimg that, restore back to stock with Odin.

I would follow his advice. Good luck!

Thanks for your suggestion.
BTW, nandroid backup -> I don't think I can use it because I don't have original backup rom?
Odin -> does this also work for LG phone?

No, you can't use nandroid backup. A nandroid is an image file of your system partitions. PC users typically know this as ghosting or cloning. To linux users, it's just a dd. You create the image yourself from a working copy. You don't need the original ROM. You can make a backup of your /system partition (nandroid) any time you have a working copy.
PS I'm an idiot. LG was literally the first thing u said. And you are correct. You need to use LG Flash Tool.
See 1942836

Unfortunately, 1942836 is not the same model I have.
I don't think I can use that instruction.
It really makes me crazy since I can't use adb at all....
I tried creating update.zip and put it in sd card to install..however, as you may know, signature verification failed.
if I could get key file to create signed zip file other than test one, that may work.
Is there anyway I can bypass the signature verification??????

Can't you reflash your system?
I think you need /bin/bash for adb to start, so without it, you can't push anything from your computer to your phone i guess..
What bootloader do you use?

Obviously, before happening this issue, I was able to use adb...
And..now..if I issue adb, then nothing shows up in the list of devices attached section...I guess because it can't communicate somehow with /system/bin/sh I just accidentally deleted.
I know that I can use Odin to install CWM for Samsung phone....I just found that there is LG Flash tool program on the internet does simialr thing like Odin for LG phone..however, I am not sure where I can find the dll that I can use from LG Flash tool program.
Any idea?
Thanks,

You will indeed have to reflash your device, as you don't have any other way of putting the bash binairy back.
I guess, as you are rooted, you know how to reflash your device. If you don't, search the forum

Help please! phone won't boot

So I think I made a stupid mistake.
I was trying to reset google wallet and It hung at 97% and wasn't able to reset. I used the google wallet installer to basically change my build prop to the nexus build prop. I figured it would just overwrite my original wallet app anyway, and once my build prop was changed to the nexus build prop I could simply reset the app from there.
Anyways, phone rebooted and it's stuck in a bootloop and isn't getting passed the boot animation screen. I can get into recovery mode and download mode just fine. I tried restoring a backup I had with CWM and it says "md5 mismatch error". I really have no idea what to do at this point, and would rather not go completely to stock since I know my data is still there. Also I'm concerned to even restore a backup because i'm pretty sure my build prop was changed. I'm also wondering if it would be possible to simply factory reset and flash a new rom on top of it.
Any help would be greatly appreciated.

which rom are you using?
extract its build.prop and flash manually (if you know how to create a flashable zip)
if you are using a cm based rom, just reflash the rom without deleting anything..
and avoid using space while renaming backups... it gives md5 mismatch error

No idea how to create the flashable zip. However I did notice a tutorial, I guess now would be a good time to learn.
I'm using darthstalker X1, it's a touchwiz based rom so I can't simply flash the rom again.
I saved all of my backups on my external SD card, can I just simply hook it up to my computer and change the backup names? And is my build.prop included in the backup I made?
Thank you for responding.

renaming the backups again might not fix
i believe to have seen a script for sgy which fixes md5 mismatch error. but you need to give commands from terminal emulator.
if you have more than one backup of the rom, try to restore system only
if any one of them works your phone will boot up again
Edit: your backups contain the build.prop file in system.(partition type).tar
just extract this
and partition type may be rfs or ext4

No idea how that is even done. I think I need windows and ADB in order to extract the build.prop, I have a mac.
I found a restore that worked, I just forgot to rename it and it wasn't too old thankfully.
I really appreciate you helping. And now I know of this mismatch error so I can name my backups correctly.

to extract backups u need a tar extractor
if the backup format is something like .tar.a or .tar.md5 rename it to .tar first
and restoring the system only of your working backup would have booted your phone (in advance restore in recovery)
anyway this was an experience too for you.. so you would be carefull next time

Restoring my system partition only from advanced restore worked perfectly. All my apps stayed how they were and I didn't have to update all of my apps after I restored. Way better than doing a full restore in this case.
Thank you for this advice, this will be a very helpful method to me if I make any mistakes while messing with anything in my system folder. And yes, it was certainly an experience for me.

Rebooting the phone and reconnecting the phone to usb may help usualy.

Who will that help? I don't see why connecting the usb will solve anything since the folder is on my phone now.
Can it be that the folder doesn't have "root-permission" ?

It's a known issue. Go to the twrp thread and search "restorecon". I'm on my phone and it's a little difficult for me to do it ATM.

Didn't work, it says. "invalid option"

Is the backup in a folder with your serial number?
Can you find the backup using TWRP file manager? Look in both /sdcard and /data/media/0 and feedback results
Also take a new backup. Does it go back to the same place?

Well that's the problem then!
Firstly do NOT restore an EFS backup. If you have EFS in your nandroid , don't restore it.
When you first take a backup, TWRP creates /sdcard/TWRP/backup/75465474566 where the numbered folder is the serial number of your device.
If you copied a numbered folder from another device, it wont find it. Similarly if you have no numbered folder, it won't find it.
Create a new backup on the new phone to create the new numbered folder then put your old backup there.
Remember, do not resorts EFS if you took a backup on the old device on yo your new one as you'll brick it..

Invalid option is the -r he did. Sometimes people have to change it up a bit. There's 2/3 different versions of that command people have to try. Its irrelevant now though, given the more accurate info we have.

Restoring twrp backup

Using a rooted nexus 5 running stock 4.4.4. And twrp 2.8.x.x
(I searched for a twrp support thread but could not find one).
I want to restore an old twrp backup I had made some time ago (with an earlier version of twrp) and moved to my pc. So I copied that backup from my pc to the twrp folder in the nexus 5. But when I reboot into TWRP, twrp lists other backups, but not the one I just copied back into its folder.
How can I get twrp to see and restore that nandroid backup?
Thank you.

My first thought is - is it the same device? I had a similar problem when I got a replacement phone, and the solution was simply to rename the old backup with the new device's id.

Yes, the same device, but different versions of twrp.

SOLVED.
Entirely my fault. I needed to move the backup file down to the next subfolder. Once I got it into the correct subfolder TWRP found it fine.

can u tell the correct folder name to place the old backup file. thnks in advance....
