If you're like me you started off not knowing how to do anything. And as time went on you learn more and more. Well I see people like me and I wanna help. I also see that people need there checksum corrected and maybe don't understand how-to do it. The info on how to do it may not make sense to everyone. Like me at 1st, I didn't understand command prompts very well. So here is a quick guide one how-to correct checksum's with Nyet's ME7sum. I have also contacted MTX for a plugin but have yet to hear back from them in over a week or so.

If you make changes at all to a .bin you will from my experience will have errors. I also have noticed that if you mod a file and then correct it and then wanna go back and edit it that you edit your "NEW" corrected file as I had two .bin files get corrupted by modding a .bin  and the throttle body would just start clicking along with a flashing CEL and no start. This was cause it had errors and required me to boot mode recover my ecu.

**UPDATE** (LINK DEAD thread deleted, sorry I will post new instructions for adding ME7Sum and Check into TunerPro again)
Just tonight I figured out a way to add ME7sum and ME7Check to TunerPro. Click link below to go to that thread.
http://nefariousmotorsports.com/forum/index.php?topic=5877.0title=


-----------------------------------------------------------

Here is short way (by ddillenger):

Download the file (me7sum), put it in your user directory (C:\Documents and Settings\usernamehere) along with the bin (we're going to call it IN for this example).

Hit START, RUN, and type: CMD

Then, type:

me7sum IN.bin OUT.bin

You'll see the program running in cmd, and will end up with a new file with the checksums corrected in the same directory you placed the previously mentioned files (C:\Documents and Settings\usernamehere). The corrected file will be named OUT.bin (or whatever you select when typing the command)


Longer Version:
----------------
*Now below is examples. Meaning this is where I put my files, and what I type is special to where my files are located. You will have to adjust for however you set things up. DDillenger suggests not to use a root folder, so please make changes to my info if you follow his advice, I am not of aware why not to, he has more knowledge in that department.

To start off download the zip file me7sum-vx.x.x.zip from http://nyetwurk.github.io/ME7Sum/
(Please be aware that there is a know issues with correction of some checksums for some errors, in this event you will need to find someone to correct the file for you that maybe has a MTX plugin).


Now extract me7sum-vx.x.x.zip and put it into folder of your choice.

(http://i58.tinypic.com/23u6kvp.jpg)



Now take your .bin file and put it in same folder to make it simple.

(http://i60.tinypic.com/27xmryd.jpg)

(http://i58.tinypic.com/23u6kvp.jpg)



Now you want to click the start button and in the search box type cmd to open the command prompt window.

(http://i61.tinypic.com/2dw85dt.jpg)



Now see pic below. You will need to type cd.. and then cd.. again to get to root folder.

(http://i60.tinypic.com/1620hhe.jpg)



After that you will direct cmd where to find your me7sum program.
File location is how I have it, adjust to your location if needed, follow the same format with \ to indacate folders.

(http://i58.tinypic.com/1ik5t5.jpg)



Now follow info in picture below
Please note, there is a grammar issues in picture. I ment to say put a new name for your NEW corrected file so you know its fixed/corrected. Do not name it the same thing as your corrupted file as it will not output a file.

(http://i57.tinypic.com/bwmlx.jpg)



After you type the above command the program will fly throw a bunch of words, you can look back and see what was corrected if you want. But if you did everything correctly you should see a message at bottom like one picture below.

(http://i58.tinypic.com/23qwww.jpg)



Now you have a corrected file and are ready to flash.

(http://i60.tinypic.com/30v2h5u.jpg)


Now if you wanna check your file, you can run cmd and type \me7sum (space) (.bin file name) you will get error check or better know as ME7Check of your file and will give you info. Again these are examples please adjust for your file locations and names of files.

I hope this helps people who might have not understood exactly how to use Nyet's ME7sum program. Please click Applaud to the left under my user ID and pic where is says Karma if this helped you. Good luck and happy Tuning and Flash folks!

Thank you for this. Stickied.

You made such a great tool for free for us it was a shame that it isn't something everyone could figure out and benefit from that I wanted to help best I could. If it's ok. I have a friend willing to make a GUI for it if I give him sometime as he's a busy guy. We talked shortly. But layout would be a select bin button. A check for errors button and a correct button. The output file would be generic labeled with _fixed added or chks or something.  With also a dialog box to watch the program at work and show results.

http://nefariousmotorsports.com/forum/index.php?topic=4698.0

That GUI is basically what me and my friend were talking about. I'm gonna take the newest version for a test drive.
Looks good. That should be bumped cause I been a member since b4 you posted it and 1st time I seen it in this thread. Maybe it should be bumped in a way or stickied.

No matter what i try i cant get this working??

says it not recognized as an external or internal command?

You need to make sure the exe is in the proper directory.

I put everything that has to be run in command in

C:\Users\DDillenger

So my command is simple. You can put the exe on your desktop however, and in cmd type:

cd desktop

After that, then type your command, but make sure the bin to correct is also on the desktop as that is now the folder used.

Thank you much this helped me extremely
I was missing the part of putting my tune in the directory.
Haha i dont know why i thought it would just find the file
But now im able to correct my own files which is awesome!
Ill deffintaly be posting my tweaks of my tune up when i make sure its
Were i want it

Hello,

Thank you for this detailed explanation.
Thank to this guide and file, I'll be able to fix a problem with a .BIN error
I try and try... "n" times to fix my issue with Win Ols, but I'm not able to found any solution, until I found this post.

p.s. this post and tool, make possible to me fix a modified a remapped .BIN file
 
Regards

Good info.  Here's how I have been using ME7Sum and ME7Check lately.

Created a folder with both programs in it and made a batch file (me7sum.bat) that's located in the same folder.  Commands are:

me7sum in.bin out.bin
pause
me7check out.bin
pause
erase in.bin

I'll copy the bin file I made in tuner pro to this folder, rename it in.bin, and run the bat file.  The pause command allows me to see the progress of each step before advancing.  Then I take the resulting out.bin file and cut and paste it back into my folder where I'm saving bin revisions.  I copy the original file name and paste it over the out.bin file name, appending it with CS to indicate the check sum has been updated.

Just a different way to get the same thing accomplished.

erasing in.bin might not be such a good idea... if things go wrong... its gone, because me7sum wont generate an out.bin

The original file exists in the folder where I keep the bin file progression, I delete it after renaming the file version with the corrected checksum.

The batch file above doesn't know if something goes wrong... it unconditionally deletes the original bin.

MSDOS sucks because writing conditionals in batch files is a huge pain. Nobody ever does it, because when they get to the point where they need conditionals, they've realized how goddamn shitty command.exe is :)

+1 bash ftw :)

No, it does not delete the original bin.  That file exists in a different directory with a different file name.  I said I COPY and paste the original bin and then name it in.bin before the programs work with it.  The original bin does not get deleted until I select the file and take action to delete it.

Does me7sum works for  me7.5???
I can check with me7check. But I keep getting an error.

Maybe. Have you tried it?

I tried a couple times but I keep getting some type of error. As soon as I can I will post a screenshot.
Not sure if its user error or just that is not compatible with me7.5

I think its because its unsupported not a user error. Nyet states it is unsupported in his ME7sum post.

to many months I am reading and rereading the entire world nefmoto !! and today managed to finish modifying and correcting a file !!! thank you for sharing the knowledge !!! pardon the !! English google translator !! ;D

awesome thread, worked first try! thanks!

ME7.5 should work now. If it does not, post the ori and the modded bin that is failing.

worked great! Thank you for this!

I want to say Thank you this post. Easy to follow and understand. Ive been really trying to understand this and finally getting around to looking for how to's. Great information. Hats off to you!

I use your tool to correct my tune checksum, so everytime you make chenges on a tune we can use this tool and then flash the ecu correctly? here are my to bin

Good day I need some advice
I have used this all in the past to correct me7 check sums  on win 10 with no issues .

Of recent  when I tried to use the app cmd just blinks and nothing happens . I tried many fixes that I could find on the internet but they did not work

I installed a fresh win7 os and I am having the same issue any idea how I can rectify this ?

I have modified permissions from read-only  but thst did not work also

Any help I would be grateful

Please copy/paste what you are actually trying to do. Do not post screen shots. Just copy/paste the text in your cmd.exe window.

BRO. the one place to get some help on this subject and your pictures are no longer there... WTF man nhaha

*** Found 73 checksums in C:\Users\Matt\Desktop\551M Bosch.bin

*** No errors were found and so no "C:\Users\Matt\Desktop\551M Bosch.log" was generated.

C:\Users\Matt>

File has no errors, its good to flash and thats why it did not give you another file
 

.log? Why? That makes zero sense

Did you notice this?

I dont no if im missing something here when downloading me7 checksum but i appear to be missing the bin file thats needed and ive tried github and nyets link

good thing you listed what exactly you did download.

I tried your link in your signature and a link from another user who was showing how it worked. When I tried the Bin file was missing.  I will grab the links and send them your way

I have no idea what you mean by "the bin file was missing". The exe was missing from the zip?

Sorry i clicked on the link at the start of this post from a member called Audiman85 and his bin file from the install file wasnt/isnt there

I clicked on yours and it took me to github near the bottom of the page it is a zip file and it says its the latest but no bin file which i believe is needed

https://nyetwurk.github.io/ME7Sum/

What do you think the "bin" file is?

Binary .

Here is short way (by ddillenger):

Download the file (me7sum), put it in your user directory (C:\Documents and Settings\usernamehere) along with the bin (WHAT AM I MISSING HERE OR AM I READING IT WRONG) !!!!                                  (we're going to call it IN for this example).

Hit START, RUN, and type: CMD

Then, type:

me7sum IN.bin OUT.bin

You'll see the program running in cmd, and will end up with a new file with the checksums corrected in the same directory you placed the previously mentioned files (C:\Documents and Settings\usernamehere). The corrected file will be named OUT.bin (or whatever you select when typing the command)


Longer Version:

*Now below is examples. Meaning this is where I put my files, and what I type is special to where my files are located. You will have to adjust for however you set things up. DDillenger suggests not to use a root folder, so please make changes to my info if you follow his advice, I am not of aware why not to, he has more knowledge in that department.

To start off download the zip file me7sum-vx.x.x.zip from http://nyetwurk.github.io/ME7Sum/
(Please be aware that there is a know issues with correction of some checksums for some errors, in this event you will need to find someone to correct the file for you that maybe has a MTX plugin).


Now extract me7sum-vx.x.x.zip and put it into folder of your choice.

You don't have a file you want to checksum?

Thanks for your prompt. I assume the bin that i thought i was on about was part of the installation lol its actually the file my file to put into the me7checksum folder in directory? I hope im making sense nice to learn something new when i get chance to get on the computer
