Nandroid Backup

Hi everyone,
I'm having issues with Nandroid backup and restore.
After flashing ARHD 17.1 from 17.0 without wiping, everytime I make a backup it says that there was an error backing up /system and when I you try to restore it, it says MD5 mismatch.
The latest backup that I was able to use was using the backup before I flashed 17.1.
Is there any way I could fix this without wiping? I'm on a vacation right now and don't have a computer handy.
Hope you can help me out! Thanks and advance happy new year!

Its always advisable to wipe data and cache b4 flashing the old backup or a new rom...its always good and prevents many issues...!!
U need a computer to solve the md5 sum mismatch error....after that if your backup is genuine (without problems) then it ll surely work..just some commands to execute...
http://forum.xda-developers.com/showthread.php?t=1975140
Scroll through the first post and you will find the proper commands..!!
Cheers..!!

Thanks! Will try that when I return home from vacation.
I just read from the ARHD forum that you can flash without wiping if coming from another version.
How about my apps and their data? I not really sure if everything's backed up. How can I make sure?

You can backup the apps and their data by using titanium backup from the playstore..! i guess thats your best bet as you dont have computer handy...!! make backup by titanium backup and then upload the backup to some good cloud sharing sites and when your problem gets solved you can restore that backup..!!
:good:

Hmm, if you rename the backup with spaces, you'll get an md5 mismatch during restore, but no idea why you get one during backup.

That's what have heppened to me, MD5 mismatch, but after removing spaces from the name of the backup I was able to restore it.

Where does Nandroid save the backups? I might have to check.
Also, how do I use titanium backup? I don't know what option to select.
Hope you can help me out.

The backup location is: sd card/clockworkmod/backup
As for titanius, I don't use it before, sorry

Just go to backup/restore (middle tab)
Then tap on the icon in upper right-hand corner, then you can select e.g. backup all user apps + system data.
Restore in the same manner. :good:

Thanks! So that's how you back things up! I was just running the 2 items under schedule and I'm not sure if that's it.
Thanks again and happy new year!

Efs folder doesn't exist

Hello.
Sorry for language mistakes, I don't learn english too much
About 2 months ago I missed imei by flashing custom rom. I thought that warranty is missed too, but service repaired my phone (at least I thought like that).
Now I want to backup efs folder, but it isn't existing . I searched with root explorer and it didn't show any efs folder.
It is surprise, that after typing *#06# phone show correct imei.
How can I create efs folder or backup imei without efs?

U cant access efs through ur phone(i mean using root explorer u cant backup efs folder) U will need to use ADB to backup although it is not needed to backup efs because custom rom only flashes the modifed firmware it does not flash baseband,imei etc. Only thing is u need to be careful with doing this kind of things.
Press thanks if helped.

That's it.
You can use EFS Backup. I strongly recommend it.

I know that custom rom doesnt change or remove imei, but what will I do if imei is corrupted like it happened few months ago?

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.
Many thanks

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.

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

I think ive messed my phone up!!! ive somehow deleted everything in my efs folder.
I still have a back up from efs pro? can I use that to restore my efs? if so how??
please help, im screwed

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

how to safely backup m919 efs folder?

hi guys,

my device on jelly bean 4.2.2

Make a backup with CWM or TWRP recovery.

Please use Andromizer Pro . in tools section you will see IMEI BACKUP OR use TWRP. i use both to be on safe side because i lost IMEI one time .

When I try to use TWRP it says 0MB backed up. Then the recovery file it creates is like 300kb
Is that right?

You can use CWM, TWRP, Andromizer Pro, or EFS Pro. Quickest method is EFS Pro. Good luck.

I'm not 100% sure as I've never had to restored it. When I was using Philz recovery the efs backup was like 50kb. Might try one of the other tool and compare.

I have it in both root of SD and the "0" folder. EFS_BACKUPS if done in TWRP. If you did it with FreeGee then in root freegee.

The root folder efs? I believe it is different from Samsung. Searching for mk9efs from system root led me here - /dev/block/platform/msm_sdcc.1/by-name/ . Searching for efs from the system root doesn't supply much, the location I just posted and a few other folders like efs-bridge. Now I may be wrong on this, @engine95 knows more than I, but I am under the impression that our efs are on 3 separate partitions and may not be accessible from a root file explorer. I don't think we have a root efs "folder". Again, I am NOT 100% on this and could be completely wrong.......

I'm not quite sure what he's asking.
The EFS backup with TWRP creates an "EFS folder with 3 files in it.
And if I remember right... @HPTesla is right. EFS is in 3 partitions. One of them is actually empty, but is still needed.
You can see the mk9efs files in the folder but that's it. Im guessing FreeGee and TWRP are basically just taking a picture of the partitions.
So to the OP, are you trying to make sure the files are there? Or are you trying to access the files in there?

? You should be able to do it from within TWRP. It depends on the version of TWRP you are using, 2.5.0.0 has been the most stable for this phone in my experience. It's an option in my backup and restore that I can check/uncheck. However, TWRP 2.6.3.0+ is needed to flash almost all 4.4 based roms and the options are different.

If you are still using the same TWRP version you used to make the backup but switched to an AOSP based rom it appears as if the backup disappeared. The backup is located in /data/media/TWRP but TWRP will look in /data/media/0/TWRP. You can copy the old backup to the 0/TWRP folder and reboot recovery.
If you are using a different version of TWRP than the one you used to make the backup, your backup may also not show up. You should use the version you used to make the back up to restore it back. I hope this helps.
