My cmu version was 51.00.351A and i tried to update to version 59.00.449A
after installed failsafe I accidently do reset via system configure and now my cmu totally bricked
(not really is my mistake but a tutorial told me to reset after every install file that is a huge mistake to trust that tutorial)
im tried to flash directly to the chip with some tool but can not found the original 51.00.351A fail safe file.
then i have to try the version 55 EU one in the fist try was none success but it was because of the cabble and the clip connected with the chip was fault.
I try again with version 31 and still failed did not know the problem was the cable conneting.
I did 3nd tries this morning and successed restored the healed binary to the chip.
Thank you so much for informations. thats every thing i need to unbrick my cmu.
really appreciate that.

need help

Hi,
I have the same chip but as i am trying to connect to it. there seems to be something wrong with the connection as it is not detected by the software. was there any specific way you connect the test clip on the chip.

Thanks
