From my title, why do i need to check if md5 checksum match when im finish downloading? Cause ive just flashed, even a non match md5 checksum but it was successfully flashed. Sorry for newbie question.

Checking the Md5 sum will verify the integrity of the download.
While corrupted downloads are not that common, they might happen and flashing a corrupted ROM might get you into ll sorts of trouble.
Better do a wipe and redownload & reflash the ROM, just to be sure.

So you mean to say, even im running now on perfectly smooth firmware but wasnt thesame md5 checksum, ill need to re download and flash again? Thanks by the way.

If it wasnt the same MD5 but it is running fine, then there is no need. If you run into any problems in the future the first thing to do would be to reflash a ROM which has the right MD5 Checksum.
Always when you can in the future check the MD5's because if you dont things are likely to go wrong and I would rather be safe than sorry lol

You don't -have- to, though I would recommend it to prevent any later problems, but if it works fine for you you can just keep it.

The only image file I would definitely check MD5 again and again is the recovery image. I flash it manually and if the image file is corrupted , I may not be able to get into the recovery mode.
If I flash a broken rom, either CWM would stop to let me know, or something is wrong and I simply redownload the rom. No big deal.

A corrupted recovery.img won't damage your phone. You need to reflash the recovery. Thats all.
I use an md5 generator only for bootloader/radio because it's possible that you get a hardbrick if these files are corrupt.

Hi everyone,
I have downloaded Android revolution us and the checksums for that and the radio are both wrong, would you suggest I redownload? Everytime I go on to check the checksums change, is that normal?
23d1522eedd44424fec40cbe7333fff1- this is the AR HD checksum, rooted already, just wanted to flash a Rom,
Thanks in advance for any help

Can someone post the stock bootloader / kernal. I tried to root and loaded the opensource kernal and now I have no wifi, no 3g and the back and home buttons are broke cant even restore factory from boor or dial pad. I picked it up today wosrt comes to worse I may be able to take it back.
The stock kernels from samsung open source are broken, its actually seems like an older beta versions "that doesn't work". I've compiled like a hundred kernels off their open source files and none of them work, i suspect there's some kind of MD5 check on the zImage files but I bricked my phone before i could try that.
You can probably compile a kernel, then MD5 the tar file then try ODINing it, that should work in theory.
Not sure on how to compile have never done it I can try just not sure if I will be doing it correctly.

I have a compiled kernel that bootloops, but I'm luckily not bricked yet. What do you mean by "MD5"ing the tar file?

I've noticed that "some" other samsung tar files end in tar.md5 which means u need to md5 the tar file, perhaps some kind of security issue, just a hunch, if you md5 encrypt ur tar file, that could actually flash it correctly. Google "md5 linux" then find out how to md5 it, that's what i was going to do next until i bricked my phone.

I don't think I understand... MD5 creates a non-reversible(ish) hash, there's no way to encrypt a file with it and then get something useable out of it on the other end... is there?

i think there is, md5 is just method for encryption AND decryption.
Factory reset
Is there another way to factory reset besides holding power and up key? I get to the menu but the new kernal disabled my home and menu buttons.

Not sure if anything has changed but we used to just delete the MD5 part and stick the tar file in phone slot on Odin...

Odin has a DUMP option i see.
Anyone knows what it does? does it dump the entire firmware or does it do something else?
I searched and no information can be found about the dump feature.
Maybe someone who is boot looping can try and see what is being dumped and if the files are indeed the files we are looking for, someone with a stock working E4GT can post their dump as well.

Hm, the only bootloader modes visually available to you are download and recovery. It's possible that it either needs to be in recovery..or the more likely scenario, while the phone is booting up. But it could be while it's booting up into recovery as well. I would try plugging it in while it's off, then start booting up into normal, recovery, and download and see if anything pops up. I know on the OG epic, when you turn it on normally, as soon as the capacitive buttons light up on the samsung splash screen, that's when the PC recognizes a device being plugged in

if you can get adb you can "adb reboot download" or if you cant try and get into recovery and see if you can adb there or if there is a download mode option.

u need the zip file....md5 sum is to verify the zip...google md5 sums if u want to learn more.

I don't understand you question just click the links in the Rom op in the development section .
Any rom you flash will have a kernel already in it. No need to flash a separate kernel. You can flash a different kernel afterwards tho. Just follow the flashing instructions in the thread.
Also try a different USB cable if your PC won't recognize your phone.

All the roms are in zip format. Md5 is used to see if some one edit the file. So the files from roms are already in zip format ...

every ROM has their dedicated thread, that has a opening post , that includes their download link, which is a ZIP file. Below the Download link in the OP the devs usually leave a set of numbers and letters which is the md5 checksum or whatevs
for example it's usually like md5: 23894238498jsafd89sf
anyways you get a md5 program or app on your computer, phone whatever, and you just check your ZIP file to see if the md5 matches.. if it does then you have a complete fresh download.
flash it and be happy.
Hi Guys
I have got the latest version of the TWRP on my phone. I have tried to flash new ROMs today and it failed at both times. What can be the reason? I have checked the md5 it matches aswell. Can I not use CWM instead of the TWRP?

I'm pretty sure your phone is rooted. Maybe you have a bad download, try to download the zip file and flash it again.
Yep can use cwm.

Hello and thanks to all those before me who give great advice on troubleshooting....
Here's my situation:
Phone is Rooted.
I downloaded an app a few days ago from the Play Store, so I could move my app installs to the sdcard. When i installed the app it said that there was something wrong " can't remember the exact message " and it needed to fix it. My dumbass allowed it to fix it and here is where my problems began.
Right after that I began receiving a message "Shell has been granted Super User", phone began to run sluggish and the Play Store App would always say it was crashing.
So I figured, screw it I would format and start w/a new ROM anyway.... I did not have any sort of backup (of course dumbass)
However I loaded up the latest version of Odin 3.09 and just incase I installed the root.zip again incase that was destroyed. Then I installed the latest version of OUDHS CWM-Based Recovery 1.0.3.3 ( Previously I had TWRP )
I downloaded a few different roms so I could see what I wanted...However...here's where things get interesting, and I did do some research on it but couldn't find a way to resolve the 1st problem.
When I first started to install a ROM, don't remember which one I was getting a signature verification failed....I had read that it could be 2 things, one the MD5 was bad, I verified that, so that wasn't the issue. Then I came across that it may have been a ROM that my device(Samsung) somehow knew wasn't approved, therefore prevented it from being installed....OK fine...
Next I found a ROM that was going to work via installing...So i picked the CM10.2 and wiped/format/davik/cache...etc... Installation took a few mins...Then when I rebooted, it's been on the Cyangenmod screen for 45 mins +....
Is there anyway I can do some verification that something further isn't interfering w/my installs?
Thanks in advance and any guidance is GREATLY appreciated...
Regards
Erik

Actually I tried that and I used this one from stockroms.net TMB-M919UVUAMDL-1366964131.zip
the verification failed immediately, however, when I checked it w/the MD5 hash on my computer it checks out...That's where I'm wondering if there is something else going on...
Or are you talking about something else regarding stock? If so could you clarify...Thanks
Use sam mobile.com
And flash the mdl fw from there. Also you may have to unzip the original file to get a tar file

This can nvr be said enough.
So I used the switch app while rooted to do an emergency recovery and it failed. Then tried Odin and it failed every time. Used Odin 3.10.7 with latest tar. Am I screwed? Stuck in either download mode or error updating software screen
Try Odin 3.10.6
Tried it as well. Is there a specific tar you'd recommend? Do you have a link?

A difference in the firmware version could account for the problem. You can go up, but not down.
I don't think that the ODIN version is going to matter, but I used .6. Go with that just to be safe.

Hmm, never ran into this before. I have one more thing for you to try.
Grab the latest firmware from Sammobile: http://www.sammobile.com/firmwares/database/SM-G920P/
Be warned, it is slow...really slow. But let her go until done and see if that works.
ok, so progress I think. It finally passed, but now it goes from the Samsung start screen to the blue screen with white android and back again (boot looping) Odined twice and same situation
