[Q] Modify ROM md5 - Motorola Atrix 2

Hello,
I'm trying to modify a couple of roms to remove some APKs and add anothers, (Supercharged and Lithium) but I keep getting md5 mismatch, even though I modified the MD5 files with the new MD5 values (using md5sums for windows)
Can you tell me what am I doing wrong / how to force CWM Recovery to ignore the MD5 files?
Thanks

The easiest thing to do is to bypass md5sum checks by leaving the md5 file empty.

It didn't work with an empty file, neither did it without an md5 file

I've had problems with if having bad checks even with an empty md5 file. formatting my sdcard fixed it. Just backup your stuff first. hopefully yo don't have 28 GB of music like me

[Q] What's MD5 checksum?

What is it? i read somewhere that if a radio and checksum don't match, it has a negative effect.
its pretty simple. its just a set of numbers and letters, if they match up perfectly with the one in the op of the radio or rom then your good to go. If they dont match you run the risk of bricking your phone. http://forum.xda-developers.com/showthread.php?t=706705

Download it again and check. No way to fix it if it's corrupt, i.e. MD5 sums don't match.
MD5 is a mathematical algorithm, used in encryption and other security applications.
When you run MD5 software on a file it performs the calculation and out comes a long hexedecimal number which is refered to as the MD5 checksum.
It's customary for this checksum to be posted along with the link to files such as ROMs and radios.
When you download, you can then run your own MD5 software on the downloaded file. It will perform the exact same mathematical calculation and give you the MD5 checksum of the file you have downloaded.
If your checksum matches the one posted by the dev, you can be sure you have an accurate copy of the downloaded file. If they don't match, then your download is either corrupt, or possibly some kind of trojan.
You should never install any software if the MD5 sum does not match the one provided by the dev. Instead, try downloading the file again, perhaps from a different mirror. If all else fails, contact the dev as it's possible they might have posted an incorrect checksum, or may have an alternate means by which you can obtain the file.

use any file manager you have and navigate to the zip file
tap and hold on it and select properties
somewhere it will say show md5 checksum or calculate md5 checksum
you will see a row of numbers and letters
then check it if it is the same withe one from the download link

HTC One S MD5 Error

Hello!
I try to install a Custom ROM on my HTC One S but during the installation i get this error:
Error: No MD5 file...
Disable force MD5 check to avoid this error
Error flashing zip from sd card
Maybe someone have an idea
Please follow the rules and only use English here.

Try to redownload your ROM and try again, sounds like you have a bad download.
You can only disable md5check for backups not for flashable zips.

I just check the MD5 using root explorer (there are many free md5 checkers), then flash. I believe TWRP also has an MD5 checker...just compare with the one at get.cm.
It is much more likely that you are not properly fastboot flashing the boot.img. Please read the OP of the CM threads to learn how to properly install the ROM.
To flash the boot.img via fastboot was successfull.
Where I`ve to put the .MD5 file on the internal storage? Before i have create a .md5 file with the MD5 Checker.
I can`t find any tutorial or threads for my HTC One S.

Put it with the ROM zip. You can also just look at the file and compare it to the one listed on get.cm.

[TOOL] Windows MD5 checker/getter GUI

Here is a MD5 checker for windows machines. It calculates the MD5 then displays a form with two buttons, you can either paste a MD5 into the text box and then check the calculated MD5 with the entered MD5 to see if they match.
Or after calculating the MD5 you can simply get the MD5 of the file you selected. Its very easy to use.
Find your file in windows explorer, right click on the file, and then select "Send To" and choose MD5 Checker and thats it

The MD5 of the attachments in this post.....if the person is downloading your app (unless they did as I have just done - I have an MD5 checker already) would suggest that they don't have an MD5 app already so the numbers you have posted seen pointless to the end user. They would have to install your app to check the integrity of the file they just downloaded.....and the purpose of providing the MD5 number is to check the download for either corruption and/or misformation caused by malware insertion etc.
Some constructive feedback. The installer looks nice and professional.
The app....how does it work? I have been using MD5 check and SHA1 and SHA2 checking for quite sometime now (so I know what I am talking about). I have mine setup through right click context menus.
Do you select the app in explorer with your app open and then go generate MD5??? No instructions?
Your uninstall method is messy and lefts junk/fragments etc in on the drive. The directory remain as well as the uninstall executable.

Uninstall isn't even mine. It's auto created by the packaging tool I'm using.
I kind of also have left this to the side as it doesn't seem popular.
And I don't know what you mean by saying posting the md5s of my tool is pointless. It's just a reference for people to familiarize themselves with md5 hash keys.
And all you do is select the file you want to check and right click it then select "send to" then "md5 checker" and it will generate the hash key then enable the interface.
Again I pretty much quit this. Nobody's interested.

one star for the sig whats up with that post in that forum? that angry person is crazy lol. Does he own the servers that run xda? i Mean is he the boss? Can't be. I dunno I gotta find out what thats about though its going drive me crazy if i don't pm me even pleasee lol
I know you said you pretty much quit this, but I just discovered it, and I am interested in getting it working as described in the OP.
I installed your program & set up the sendto, but the MD5 Checker.exe GUI front end for md5sum.exe isn't working. "Get MD5" doesn't do anything, and "Check MD5" always returns a mismatch.
Is this incompatible with Win7 x64, or have I screwed something up installing it?
Thanks.

[Q] MD5 Mismatch error even AFTER clearing nandroid.md5?

So I had the md5 mismatch error and the easiest solution was to use a text editor and delete the contents of the nandroid.md5 file under Clockworkmod/Backup/(NameofBackup).
Well I did that but now when I try to restore I get the md5 mismatch error INSTANTLY, so I'm assuming that just made things worse. How can I fix this?

What were you attempting to do when you received the error message? Flashing from CWM recovery?

But what will happen if you try to restore a backup and you get an error the Md5 Mismatch error.
It happened to me also and after a little tries I was able to sort it out.
I am sharing to help other fellow users of this device.
Here is the process..
1-)Go to sdcard/clockworkmod/backup/[your backup name]/here
2-)Copy the nandroid.md5 file and keep it somewhere safe.
3-)Open the nandroid.md5 in the backup folder file with any text editor and DELETE all the inside contents.
4-)Now save the file and try restoring your backup again.
5-)This will OVERIDE the md5 checks and the restore will begin.
All done enjoy nandroiding...LOL..
Press the thanks button if i was able to help you...
