when i heated the epoxy i accedently destoroyed line 2, 3, 4, 5 but i just scraped the copper on the lines and solderd cables instead

but i got some issues now, the passkey blinks and go to mode b in windows but when i try to extract the firmware i just get "the data dumped does not match its own checksum" and i get a illegal firmware that toolbox doesent recognize

does all the lines need to be fixed in order to flash my 79 or is it something elese?

that means the lines are broken for i and and h....

You picked a bad time to link to that pic, looks like the domain it was on expired.

I don't think I and H connect anywhere on that pic, though you still need to have them connected to the key itself. The one between F and E needs to go to ground and the two to the right of I should be connected to some points.

You might have damaged something else while heating...?
