Connect LT-Unbrick to the T-Side header using the provided ribbon cable.

Connect the LT-Reset jumper to the E-Side header.

Connect LT-Unbrick to the PC using the supplied USB cable and establish which port it is connected too. If you do not know how to do this, right click on the windows icon on the bottom left, select Device Manager. Then hit the > arrow on Ports (COM & LPT). This should give you a list of the com ports. You are
looking for the device called USB-SERIAL CH340 (COM ??) This will show you what com port it is on. If it shows up as unknown, please install driver from the
flash drive provided in the kit. Note the com port, the same port will be used later for the E-side programming as well.

Power the PCM using the black and blue connectors on both boards

LT-Reset tab LED should light up when properly connected to power/ground.

Run the software LT-Unbrick.exe

Select T-Side

Select the COM port you are using

Select Connect and wait for the COM Status to go green

Select Information, wait for the process to complete

Manufacturer code should be $89 

Device code should be $B4

Ignore the Whole flash checksum. GM checksum should match with the content of $2018. If you reprogram with the file I sent you GM checksum will be $2BBD

First Step:
Select Zero. This programs all bits ($00)
GM checksum will now come back as $0000

Second Step:
Select Erase. This erases the entire array to $FF
GM checksum will now come back as $8818. Checksum = ($FF *( ($E000 + $8000) - 18)) & $FFFF

Third Step:
Select Program
Pick the source file
Allow pcm to program without disturbing.

Once programming is completed, you can power down the pcm and hit disconnect and remove usb cable from the LT-Unbrick module. Now you can pull the ribbon cable from the T-side header and pull the LT-Reset tab from the E-side header.
