md5 is a hash function, you're using it to check that your image isn't corrupted.
A quick search will turn this up:

Hint, use this command on your device:
`busybox md5sum [image location]`

I see this a lot here lately. What exactly is it and what do you use it for?
Very basically MD5 gives a value of the file it is referencing. If you see a file with a MD5 sum next to it you can download that file and check its MD5 sum to ensure the file downloaded properly. There are different programs for it.
Certain Odin and other files will be signed, for lack of a better word, with a MD5 sum. When Odin runs it checks for that signature and if found it runs a MD5 sum check. If the signature and check don't match Odin will fail.

Howdy mate.... I stumbled upon this thread by accident, so I don't have the issue you experienced, but might I suggest that you explain how you fixed your issue, or post a link to the pertinent info?
That way if someone with the same problem comes up here it won't be a dead-end and there will be a solution attached to this thread, making it useful.
Share the knowledge
yeah, what did you do???
i have experienced that too.. and havent got the answer.. so the only thing i could do was just restore my other backup but was a month after the latest backup.. how did you fix it?

Because file in /system/bin is md5, not md5sum

I have the same problem, I backup from cwm, then when I want to restore with the same version of cwm, the log sais md5 missmate,
Question guys. I'm trying to restore a nandroid backup and keep getting the md5 checksum mismatch error. I have a few nandroids that work at the moment. I know this is a stupid question but I thought worth a try. If I replace the files from the nandroid backup that gets the md5 error and move all the files over to a nandroid thats working, is this possible? The only file I won't be replacing is the nandroid.md5 file. I've moved the boot, cache.ext4, data.ext4, system.ext4 files that I would like to restore. Thanks in advance guys!
Please close thread. Got it fixed!

Actually if you're trying to restore a backup and get that md5 mismatch error it usually means that there is characters in the backup's folder name that it won't recognize, try renaming the backup folder name with no spaces or hyphens, I usually only use letters and numbers with no spaces, try that and it should be ok at that point...
EDIT: Also I don't recommend moving the files into a working backup folder as the md5sum is generated for each specific backup and you could have problems if the md5sum doesn't match the files that they were created for...

Hi guys,
I currently have a Zopo ZP300 phone
I have no issues getting CWM to install or work, but when trying to create a rom backup things start to go funny.
Firstly, the backup takes hours to complete.. 2~3 hrs.
- I end up with :
boot.img approx 3.8 Gigs in size
cache.ext4.tar approx 17kb
data.ext4.tar approx 334 MB
recovery.img approx 3.8 Gigs
system.ext4.tar approx 386 MB
Secondly, when the backup completes, i am greeted with "Error while generating md5 sum"...
I have factory reset the phone, i have wiped all caches, Dalvik etc, etc... no luck.
I have also tried Terminal Emulator to generate a MD5 and end up with nandroid.md5 of 0 Kb in size which is useless..
Anyone ??
Get 4EXT recovery and you will never have any sort of problems installing or updating custom roms. Its free, constant updates, touch based interface, and easier to use than clockwork.

Is it compatible with ZP300 ?
Can you make backup with it ?
Cheers
Not sure about compatibility but yes you can make backups everything you do with clockwork you can do with 4EXT and more

Ok.
I tried again to make a backup, but again i get "could not generate md5 file" error.
So now i tried to make md5 using ABD and md5sum command, but i get "sh: md5sum: not found" error.
I also tried terminal emulator with same result..
Now what do i do ? Why do i get "not found" error ?
Is there another way to make md5 ?
I really need to make a reliable nandroid backup...

Recovery might be generating a corrupt md5.
Ok try this:
Code:
cd /sdcard/clockworkmod/backup/XXXXXX/
rm nandroid.md5
md5sum *.img > nandroid.md5
This should do the trick because the md5sum file must be named nandroid.md5

It actually generated a MD5 file. :laugh:
Now, as i type, i started a recovery process to test, and so far so good.

**UPDATE**
Restore completed successfully !! Yay !! :good:
Big thank you to those that helped...

There ---> http://bbs.zopomobile.com/forum.php?mod=viewthread&tid=21332&highlight=卓普ZP300
The site is in Chinese but Google translate is your best friend. Also, you need to register in order to get the app.
ALso, the app is in Chinese, but the menu structure of CWM is the same as the english version of CWM.

Forgive me, but unfortunately my native language is not English ... So .. my research on this forum are very complicated.
After several attempts and with great difficulty I managed to download from droidbasemment "cm-10-20121030-EXPERIMENTAL-p4.zip."
At the same address I see that there is a file "cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum" which I think is the MD5 of the ROM file of 152.52 MB.
If so, how can I verify the MD5 to make sure that the downloaded file is not corrupt?
Many thanks to those who want to answer. Hi

most recoveries will verify the file automatically if that md5sum file is in the same place as the ROM when you flash it. If you want to make sure now, just open the md5sum file in any text editor to see the correct md5 and then look at the properties of the ROM zip file and look at the calculated sum there and confirm they match.
kRel there is a app just for this, I have it on my pc, give me some time and I will post it for ya. dill

The problem is that ... if I open the zip file "cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum", inside there is nothing!

Thank you ... this applet I also have in my computer. It integrates in "explorer" and is called "HashTab v3.0.0"
But the problem is that inside the file: cm-10-20121030-EXPERIMENTAL-p4.zip.md5sum nothing!
If you have the Wifi 7510 tab that is the wrong md5, you want the p4wifi md5

Do you have winzip or 7zip, you need a file extractor to open the md5 zip?

also...
search market for md5 and you'll find a ton of apps the will calc the md5 from a file you can compare that to the hash inside the md5 file posted by pershoot.
md5sum -c /path/to/file.md5
The *.md5 file and the file it corresponds to must be in the same directory together. This works from your device in a terminal as well.
I discovered the mystery ....
Opening the file from linux (ubuntu) shows a normal text file containing the MD5!
CWM is also able to read and verify the MD5. But I have not understand how to.
Maybe you need to copy the file to your tablet also MD5??
