[Q] What is MD5 Sum?

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.

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]`

MD5 for roms/kernels

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?

[Q] original factory partition MD5s? (need correct cache/hidden.img.ext4)

Hello everyone,
I made the mistake of rooting my SCH-I545 before taking an image of the factory rom, and I want to ODIN/heimdall back to factory. I have found a few "factory ROMs" online, but the contents of those slightly differ. Does anyone have (or can anyone generate) a list of MD5s for each of the partition files? The ones I'm most curious about are cache.img and hidden.img, as those two seem to differ. This is what I've found:
Code:
MD5 (I /aboot.mbn) 801c2c74e4f413d1e3bff753a554727a
MD5 (I /boot.img) b5b9f789628631cf4ac5d12d863995d7
MD5 (I /cache.img.ext4) 6a0476796321f5b88c1903eedff873ab or 6b26a090d3853ee2871dd436fe74bfea
MD5 (I /hidden.img.ext4) 93e20ce35250b8297af5a86dea812253 or 53d568a0a7d0b8bc368354edf1e38ba7
MD5 (I /modem.bin) c96cf6135b25fd9f25bfe407b05114bf
MD5 (I /NON-HLOS.bin) 8caf495082518fc1ee65834ddbd812ba
MD5 (I /recovery.img) 80636fd1b6eccb0a1c26a9c1b0c4d823
MD5 (I /rpm.mbn) e6d1387cbe81b9d8fac69b510c318bd3
MD5 (I /sbl1.mbn) b0c3a5577833e69f1e3ff322460ec018
MD5 (I /sbl2.mbn) dbc1f9659654fd1f309f9ec31bffaed7
MD5 (I /sbl3.mbn) 60d806475c300e98a7830050d439ff42
MD5 (I /system.img.ext4) b4635db409883eaf936558f38506656a
MD5 (I /tz.mbn) 4dca269187856d7c99e8d470f3453079
Thanks for your help.
