MD5 error

Why do I get md5 error when I rename a backup? How can I rename my nvflash backups without the md5 error?

Easy don't renane the backup folder with spaces use underscores to relfect spaces ie: cm_7

Ohh ok! Thanks bud!

yup never any spaces because then it causes dumb **** like an md5 error

CWM Recovery - MD5 mismatch

Hey there,
since a few time I can't restore my recently made backups..
Everytimes I want to restore the CWM Recovery says
"Checking MD5 sums
MD5 mismatch" ..
I've already searched the forum and couldn't find a thread in here..
Also the solutions I found on google didn't help me..
Any tips?
Thanks in advance..
EDIT: Recoverysystem is 5.0.2.0

I've had this happen once when I went in and changed name of my backup from cwm's default date and time naming to something else. Other than that not sure why you'd be getting mismatch error except for a maybe a bad sdcard.
You could try reflashing the recovery to rule out a bad flash of the recovery

Well, I didn't change the name..
Reflashed the recovery, still got the Problem.. :/

Could be a bug in the recovery. I'd try flashing another recovery and see if that helps. Lots of different recoveries out there so just make sure the one you try supports your phone.

Of course it supports my phone. I've installed it from ClockWorkMod and chose LGE Optimus One. And it worked a few time before without problems.. :/

Found this you might try to rebuild your md5smd5s

Hi,
I also got the same problem some time ago. But for me this is because i deleted the ext partition on my phone after the backup has been taken. So i think any hardware changes may result this.

So this might be because I've changed SD-card for flashing another ROM in between?
@kwkbnk : Thanks, but I've already tried this before...

I had this problem on one of my phones. I had deleted one of the files. (an extra sd-ext backup file that I did not need). The first thing that recovery does is check the MD5 sum of all the files. If it can't find one, it just says MD5 does not match and stops. It tries to check all files even if you tell recovery you only want one restored. I fixed it by modifying the nandroid.MD5 file. It is a text file with one line for each file, listing each file's name and its MD5 sum. I just edited the file and removed the line for the missing file and all was well, I was able to restore all the other files with no errors. I also noted that I could remove all the entries so it was an empty file and recovery restored all files without checking MD5s at all. That's not a good idea in case there is a file error, but there may be times when it's necessary.

Where do I find the nandroid.MD5?
Couldn't find it anywhere..

Mine was in the same folder that had the img files. Clockworkmod/backup on your SD card. There is a folder inside that for each backup you have made.
EDIT: I just looked at that referenced post above and that script first removes the nandroid.md5 file and then rebuilds a new one. If you got an error and the script did not finish, then there would be no nandroid.md5 file. If you feel brave, you can create an empty nandroid.md5 text file and I believe recovery will skip the md5 check. At least it did for me. That's no worse than building a new one from the files you have with the script. If there was a bad file, recovery would try to install the file anyway since the new md5 sums match.

For me it happen when my memory card storage is low I did a backup.

You can find the solution a view posts before, as already said.
I've uploaded an empty nandroid.md5 which causes the md5 sum is not checked.
Just copy it into your backup on SD (for example /clockworkmod/backups/2011-12-01.13.55.09).
You can find the MD5 here (xda-attechments don't support .md5-files).
Remember it could crash if your error is not caused by an missing nandroid.md5 .

OMG, helps alot
my eternal thanks

Thx unicycler! Saved me a lot of hours of frustration -I was just about ready to reinstall minicm7 on my X8 when I saw this thread! Your uploaded file fixed it all.
Thank you!!!

Leapinlar, please, can you reupload the MD5? The download link is broken

I will do this evening. Just forgot to do..

clockwork-recovery MD5 mismatch FIX!

HEY GUYS I JUST FOUND THE KEY TO THE PROBLEM---clockwork-recovery MD5 mismatch IS VERY SIMPLE...
1.OPEN SD CARD IN WINDOWS.
2.DOWNLOAD 2 SOFTWARES ( MD5 CALCULATOR AND NOTEPAD++) JUS GOOGLE THEM AND INSTALL.
3.OPEN CLOCKWORK FOLDER IN SD VIA COMPUTER->BACKUP->(YOUR BACK).
4.NOW RIGHT CLICK ON NANDROID.MD5 AND EDIT WITH NOTEPAD++
5.GREEN HIGHLIGHTED PHRASE IS A KEY.
6.RIGHT CLICK ON REST EVERY FILE IN BACKUP FOLDER INDIVIDUALLY->MD5 CALCULATOR
7.MATCH THE KEY TO THAT OF NOTEDPAD++ FILE
8.IF THEY DONT MATCH COPY KEY FROM MD5 CALCULATOR AND PASTE IN NOTEPAD
9.SAVE AND EXIT.
10.NOW TRY RECOVERY IT;LL WORK.

MD5 is there for a reason...

what reason??
can you share??
(and why did you change the name?)

Wikipedia said:
MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact. For example, file servers often provide a pre-computed MD5 (known as Md5sum) checksum for the files, so that a user can compare the checksum of the downloaded file to it. Unix-based operating systems include MD5 sum utilities in their distribution packages, whereas Windows users use third-party applications.

Successful verification of the md5 file shows that the files are the same as at the time of packing and "not corrupted".
Consider this,
You flash a ROM which did not have a correct md5 checksum.
It may mean that the ROM was corrupted due to some reason and you may end up with a bricked phone.
though the chances of this happening are pretty low with a backup.. but better safe than sorry.
and i changed my username cause i liked it

Well yeah, MD5 is a great thing when it comes to checking consistency of a file, but for example, it bothers me because i have about 5-6 rom backups and they are all difrent roms, so i need to change the name of folder from date-time stamp to name of the rom, but when i do that i cant restore it any more because MD5 checksum apperantly checks the folders name also so i have to rename it again to date stamp... but sometimes it can be useful... just sayin'

I don't think cwm checks the backup names. I've got a couple of backups renamed to the ROM names and they work well.

well i dont know then, when i change their name back to the time stamp like 2012-03-15 11.12.32 then the restore will work, but when i leave a name like CM 7.2 rc5.5, when i chose restore, it prints out md5 checksum mismatched...

Same thing happens with me too..renaming the cwm backup file leads to the same mds mismatch error but sometimes it works..strange eh??

That never happens for me...

Well I am an experienced hacker so ill explain. I do not have a brief knowleage about md5 but the md5 is calculated by the alphablet that it has lets say the name is ABHY then the md5 will be 1670 (This is an expamle) the other name is ZXDR the md5 will be 7304 now if you change the name the md5 does not change hence the error arises

yeah i know that, but i thought that he makes MD5 checksum of backup files, one by one, and not the whole folder...

It looks like this is the case, I havejust spent the last hour trying to "repair" the Md5 checksums as described above only to find there was no problem with them, the problem was i had renamed the backup file. on checking in details when the file was created i renamed the file accordingly and voila the backup worked. I have renamed many backup files before and never had this problem but i did this time strange.

Informative post...
but MD5 checksum verification is useful...

I got md5 checksum error and it was caused by space in renamed folder name. After i remove space, restore worked.

Blobs?

In my recovery mode there is a large file called blobs(about 700mb) .can anyone tell me what it means?? Also for some reason my backup is of 16mb only..

Dude my bad i did not search!! Thanks so much...
So here's what i understood-
The blob file makes a common back up file for all backups n only the difference in diff backups are stored in the folder' backup' right?
In other words when we make a backup
Only the files that are different are backed up.the rest are restored from blob
So both backup n restore well be faster

Re loneagl, do you need to to backup for a very long time？It took me at least 7 mins.
Sent from my GT-I9003 using xda app-developers app

Yep..it stays at 'freeing up space' for long time.(i actually rebooted once thinking it had hung up)..the actual backup is only about 20 mb..the blob file about 800mb

there will be a folder in your SD card called twrp..go in that folder and paste the 'backup' folder in that.....make sure once you paste the back-up you reboot the recovery once again..just in case and than try it.
even after that if you face any problem than i would recommend using the latest CWM recovery.I personally find it easy to use and i have also faced few problems with twrp

than just do the back-up 2nd time after installing CWM recovery.
And,remember from the next time don't just cut-paste the folder with the name 'back-up'...cut the whole clockworkmod or twrp folder from the SD card...that would be detected easily...
