Greetings,

I happened to restore a nandroid backup i created but encountered an "md5 mismatch" error. Here is a solution that my geeky cousins handed me.

STEP 1: Open Terminal Emulator

Step 2: Use the following commands. (DON'T FORGET TO REPLACE "2012-04-17.10.09.36" WITH YOUR OWN BACKUP FOLDER NAME)

su
# mount -o remount rw /sdcard
#cd /sdcard/clockworkmod/backup/2012-04-17.10.09.36
#rm nandroid.md5
#md5sum *img > nandroid.md5

STEP 3: (This will create a new "nandroid.md5" file without ANY "md5 mismatch" errors.)
Reboot your phone and enter Recovery (Home+Power)
Restore.

Hope this helps,
UsmanJ

little clearance before i proceed :

1. for example i have a folder name : 2012-04-17.10.09.36

2. now i have to rename it something like XYZ so now 2012-04-17.10.09.36 will be XYZ

3. now i will do this :
su
# mount -o remount rw /sdcard
#cd /sdcard/clockworkmod/backup/XYZ
#rm nandroid .md5
#md5sum *img > nandroid.md5

4. thats all or did i do something wrong ?

Your 3rd screenshot, your proceeding fine, except that there should NOT be a space between nandroid and .md5. This causes Terminal Emulator to recognize the command to be applied on two different files.

It is supposed to be "#rm nandroid.md5"

I can confirm this procedure worked on my SGS2.

I had a backup that I decided to rename it to something more meaningful than 2012.09.12.... to jbrom a.k.a. jelly bean ROM and when I tried to restore from this backup Igot the MD5 error mismatch message.

This solution worked great on my JB SGS2...

I only had to use the backup on my SD card which was located on this path

/mnt/extSdCard/clockworkmod/backup/jbrom

I found out my backup did not have a nandroid.md5 file on the folder. Somehow it got deleted.

Thanks for this solution:good:

How to know if backup works?

So I have a question.
How do you actually know if a backup does actually works?
Because I sometimes read that when a back-up is bad itself it could brick your phone.
Or a file is missing and you still get nowhere.
And since there is a md5 mismatch error, I guess something went wrong.
It's my first back up ever and I can't seem to find a answer to this question.
I back it up with CWM (5.0.2). And have a Samsung s5830i.

When in the folder backup (sd/clockworkmod/backup) I see a folder with a date and time.
I assume that's where my back up is.

In this folder there are 4 files.

Cache.rfs 5.3kb
data.rfs 25.5kb
nandroid.md5 1kb
system.rfs 221.9kb

Are those files as big as it should be?
Some web sites says that it should be around 1 Gb.
And is there a file missing?


Thanks in advance.

i have a question,
my problem is a bit different but not at all.


i did a nandroid back up of my hugoboss stock rom. when i tried to restore it, it says that there was an error to restore system because of rfs format.
then i discovered that the problem was because recovery format in ext4.
so i used cf-root app ( i can't remeber the real name) that reboots my ace is recovery and format system in rfs, but now when i tried to restore stock nandroid back up it says me the problem of md5 sum mistmatch.

now i can try this guide?? or my problem is another cause first it gave me the other error??
i will have some risks doing that?

thanks






EDIT:



i read ( i can't rember where) of another way to fix this problem. it says to open nandroid back up with an edit-test app and to modify some lines.

what metod is better for my problem??
