When the MRA hack is done right it works perfectly without any problem.
There are 2 main reasons why you get status 0x51 or 0x52 :
1 . The tracks have not been cut properly. Make sure you can see them with you eyes and not a magnifying glass. Dont be too scare , make sure they are deep enough.
2. The soldering or wiring is not done properly.
Once you have done everything correct (I use the original MRA hack as described in Jungle Flasher) and it works 100% perfect, as long as the job was done 100% correct.
Do a good clean job, nice cuts , good soldering , as described by boxxdr. But when it comes for wiring i going for the orignal MRA hack. boxxdr wiring configuration has not yet worked for me. Will give it a few more tries.
Remember if you are getting status 0x51 or 0x52 you need to cut deeper tracks.
Once all done use this method.
Power off to drive
Switch set to 3.3v
Select MTS tab
Click on Intro button
Now Power the drive ! - Not before.
It should take less than a few seconds for it to load status 0x72 - If not
Now flip Switch to resistor
Done! Disconnect machine half assemble and test.
Go back and check the tracks, check your soldering and then your wiring config
I have used 22 omh and 20 omh resistors . Both work amazingly fine.
Dont forget ! never give up ..its not the board its you! so double check your work.
In case you are freaking out and getting furstrated becuase a 20 min job has now turned into multiple hours over multiple days... It is still your mistake. So dobule , triple check your work.
I guarantee that once done 100% same as MRA hack , and then follow my steps
