[Q] To MD5sum or not to MD5sum? - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

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.

[Q] Q: where is the md5 file

I`ve downloaded this rom :
http://forum.xda-developers.com/showthread.php?t=1237495
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.

Flashing ROM VERTREMA

Hey guys,
been a lurker for long...
anyway, I downloaded VERTREMA ROM cz I love the ICS theme... so I rooted my SGS2 using CF-ROOT guide here
Checked it using Root Check Basic tool, and it says i have root access... so my sgs2 is rooted
so.... i tried to install this ROM using CWM app... i tried using update, chose the file, rebooted but didnt work... it says something E: can't open .....zip
What did I do wrong?
BTW, i placed the ROM inside /download/ folder (not in external SD)
Thanks,

Did you download the entire package ? it may happen if the download got interrupted mid way ......... in that case you'd have a zip file of a lesser size which can't be opened ....... try extracting the zip if you get an error you've got to redownload the package....
also ensure that the package is not read only (just incase)

ok... package is not read-only... it's -rw... so it's good....
how do i check the md5 checksum in multiupload?
i m downloading the latest version now... hope it wont get disconnected...
Find an app like MD5Summer (Windoze) to check the MD5 sum once you've downloaded the package.
Also, you can use pretty much any archive program (7Zip, IZArc, WinRar) to test the archive once you've finished downloading it.
If it comes up with fail for *any* file, don't flash that package/download it again. You might have to try downloading it from a different PC/internet connection like I did a while back when I was having probs downloading roms from home without them being corrupt.

no no... i mean before i downloaded the package.... is there a md5 checker tool so that i can compare wit the one that i downloaded?
ok i will try to download using another pc..
You have to finish downloading the rom/package before you can check the MD5 sum as there's nothing to check if you haven't downloaded it (obviously)

yes i know... what i meant was,... is there like a website that tells me the md5 cs in multiupload, so i can compare to the one that i had just finished downloading...
anyway.... thanks to the above poster.. i deleted it from my phone and then transferred the file again... and now it works.... weird,... i transferred first to my microsd, then to phone... i guess that method doesnt work... better to transfer it directly to phone...
thanks y'all!!! been a great help... very nice community here
The MD5 checksum is usually listed next to the link where you download the archive wherever you're downloading it from. Honestly, it's not that important. The most important thing is you get the entire file. And if you "test" the archive in 7Zip/IZArc/WinRar & it comes up all files OK you should be fine.
I've never had a problem flashing a rom/kernel where the test in IZArc has indicated all files contained within are OK/the archive isn't corrupt.

ic.... oh well.. thanks anyway .... ohh 1 last question.. so if i want to revert to the stock rom, i just do the same thing but with the stock rom i can download from samfirmware?
Why not download the stock rom from here ? I wouldn't know about files from Samfirmware as I've never downloaded anything from there.
If you want to go back to stock, download the rom from Intratech's thread, flash it in Odin, done. Again, test the archive integrity in IZarc or similar to make sure it's OK (given you seemed to have had some problems downloading an archive that wasn't whole or corrupted).

[Q] how to unpack tar.md5 ?

Hi,
I downloaded a ROM from sammobile.com for my galaxy tab 10.1, and all I want is system.img which is located in a tar.md5 file .
if I extract is with 7zip I get a message "there is no correct record at the end of archive"
and dsixda kitchen don't seem to recognize it .
any ideas please .
thanks.
Well its simple just rename it to .tar and use winrar to extract it. the md5 extension makes odin calculate a hash to check if the firmware you're flashing is not corrupted.
hi,
I did that and I got a message "there is no correct record at the end of archive"
the files are extracted but I think it is corrupted because dsixda kitchen can't read it.
just extract it by 7-Zip and don't care about message
I have this problem too, my 7-zpi say that canĀ“t open file format unknowed or damage.
your download maybe interupted, try download it again and do md5 checksum

You might be opening the wrong file.
You have to download 2 files:
xxxx.tar
xxxx.tar.md5
the first one is the one you have to open.
the second one is the one that only have the MD5 result of the first.

Redownlaod and try to unzip again. Kitchen should open it, make sure u have kitchen scripts for your phone or edit from flashable zip. Afaik
best idea
dont use 7zip but use unoversal extractor. it will extract everything.
I have the same issue for 5301. I have to get either the recovery or system img for creating a custom rom. Usually samsung firmware files can be extracted using izarc, 7zip or universal extract tool. some can be opened with ultraISO or similar tool. I tried dsixdas kitchen as well. That does not even acknowledge this ROM. These firmwares come as a single tar file with md5 sum attached. There is something different about this ROM file that wont even let let the regular tools see what is inside the file. I tried to open it with a hex editor and it looks similar what a regular tar.md5 file would look. Looking at the log file from universal extractor:
TrID/32 - File Identifier v2.02 - (C) 2003-06 By M.Pontello

99.3% (.TAR) TAR archive (149/5)
0.6% (.LZMA) LZMA compressed file (1/1)
7-Zip Tar archive extractions cannot be logged.
If Odin can flash these files using the same boot, recovery and system... images then there must be a way to extract these img files. wonder if odin extracts to a temp location?

Use odinatrix to extrat system.img n modem files..
Its the easiest tool do so...
U may also use splitfus2 bt its way trickier to use than odinatrix.

Now there is only one xxx_home.tar.md5 file..
That was old days.
Be a part of new world.
N now u cnt extract through an archve manager.
U need espicial tools like splitfus2 n odinatrix to extract files.

Thanks SArnab! so finally I am able to split the files using odinatrix. Now for this type of turbo ROMs how do I create odin flashable file???
I created a regular odin tar file with md5 sum but that does not go past 'NAND Write Start'. Please advise.

Your pc shud b superfast so that odintrix can work witout lag.
My HP G6 lapi took around 10 mins to extrqct the one .tar.md5 file..
The tool will automatically extract diffrnt .tar files such as modem_xxx.tar pda_xxx.tar n csc_xxx.tar
Now u can use these to flash through odin witout any prb.
U can use pda.tar in kitchen to get boot.img n system.img.
Kitchen will also help u extract sysmtem foldr from system.img.
U can also flash through odin the single .tar.md5....
Choose that in pda field...
Odin is smart enough to do rest of the part.
Don't be lazy.

Appreciate the quick response. I guess my question was not clear enough. I extracted the recovery and created a clockwork recovery named recovery.img. Now I want to flash this recovery back on the device. I created the tar file using:
tar -H ustar -c recovery.img > CWMrecovery.tar
md5sum -t CWMrecovery.tar >> CWMrecovery.tar
mv CWMrecovery.tar CWMrecovery.tar.md5
When I flash this using odin3_v3.07 md5 is verified but he flash does not go through and stops at NAND write start. Is there a special way to create a odin flashable tar.md5 file foe these turbo firmwares?

[Q] Create file flashable through Odin?

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
speed_bot said:

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.....

Solved

Hi guys,
I'm trying to set up ota updater centre for my rom. When I'm registering the rom, it needs the MD5 sum of the rom. I have downloaded "MD5summer" but i cant check the md5 sum of all the zip file, only for the folders inside it.
What i'm doing wrong?
If i'm right, what code should I take (system or Meta-inf)?
