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.

Thanks for the clarification.
I`ve downloaded this rom :

and was running odin, but can`t find the md5 file
where did i go wrong??
Rune
you did not do anything wrong.
the developer packaged it as a zip file instead of a md5 or tar file.
it must be flashed through your sd card and CWM recovery method as a zip file.
hello, has been posted in the forum roms and kernels, but has not been posted MD5, peopl developers to post the MD5 to help those who download.
Sheldon, Your post is difficult to understand but from what I gather, you would like developers to post MD5 sums for files. If this correct let me respond by saying that my ROM's have an automatic MD5 sum in the file and the file is zipped. If the zip file is corrupt I would expect CRC errors and you can't flash a file that you can not extract. When you go to flash the file, Odin does an MD5 checksum and you can not flash it if the checksum fails. By zipping the file and including the built in MD5 sum. I am insuring that people are not flashing garbage to their device.
Is that what you are worried about?
Hey everyone
I have a question which I coudn't find anywhere on the forum for an answer...
I have a firmware for my galaxy ace named S5830XWKTM_S5830OXXKT3_S5830XWKT7_HOME.tar.md5
and I wanted to edit the baseband so I could make it work in my S5830L by just changing "amss" file...
But I can't change it if they are in .md5 and if I change the file to .zip and transfer amss, I can't change it back to .md5
How can I turn S5830XWKTM_S5830OXXKT3_S5830XWKT7_HOME.tar.zip into S5830XWKTM_S5830OXXKT3_S5830XWKT7_HOME.tar.md5
I don't know if you understand my question...
so here is what i understood you want to extract the. tar file change a file and repack it right. ... how different is the l version different from the Normal one

yes
The only difference is the frequency for 3G
S5830 uses for HSDPA 900 /2100
and S5830L 850 / 1900
By deafult odin has checksum md5 verification thats why there is a .md5 extension even if you manage to repack it the file wont get flashed through odin......
i have a workaround for you
flash the file directly there is a tutorial to extract and flash only baseband use that after flashing that zip .......

I think I found it
I just created my .tar file to flash it through Odin.
But I have a question
Can I create a .tar file with the complete firmware and flash it through Odin?
followed this guide http://forum.xda-developers.com/showthread.php?t=1558715
I just added everything that was in the .md5 , replaced baseband file and put it back again in a .tar file
you can but need the change the checksum to the new value its better if you flash it seperately

Oh, but what do you mean with changing the checksum
the checksum is only to check if the file is corrupt or not or if it has been modified...
well checksum adds up all the files finds it's size and store's it when yoy change a file they may be of different: sizes so the checksum verification fails

Its not like im using the same .md5 file.
All I did was extract all the files from the .md5
Repacked them into a .tar file and it should be flashable through Odin...
Since its not .md5 it won't do a checksum
I added the .tar file into Odin - "One Package" and doesn't give me any error or anything... So I guess it should work the same as changing baseband does.
EDIT:
Thanks alot for your help
I managed to repack all the files to make a firmware flashable through Odin
All I did was this
$ tar -H ustar -c (all unpacked files in here) > firmware.tar
$ md5sum -t firmware.tar >> firmware.tar
$ mv firmware.tar firmware.tar.md5
I just flashed it through Odin and no problems at all
i thought that you were using the base ace rom by changing the file so said that checksum would vary btw your problem is solved right edit the title thread to solved it will say others time.....
Hi all..
I have been using the Zip files, via CWM to update my CM10 versions.. All is well..
But I see the md5sum files that one can flash with ODIN there as well..
So my Q is: Do I need to flash the MD5's as well? If so, for what point and purpose?
Regards
T
Md5 files are checksums for the file you are downloading. Its basically a way to verify you have downloaded the complete file and that its the file that it says it is.
