my vertyanov jig wont work, Lenovo NM-273

[ktmmotocross]

Hello.
I have problem with my Vertyanov JIG v3.3 that wont work.
I test it with NM-273 which works correctly. connection test with JIG works ok, but when i connect board JIG cannot check connection with board

Im using SW from this site, but windows tells me it is Trojan in it. I dont care so i turn defender off, but still no connection to IT8586E. Board is powered, GND cable is connected.

Hello KTM.

Check all connections and also check for power supply for kbc +3valw. Sometimes you just need to press the power buton once prior preograming to get it to work. I know it sounds nonsence but try it.

Option 2 is to remove PR337 and connect the PU904 jumper contacts to get that 3v.

Most of the problems aren`t with the programmers.Use a very short gnd cable and check the KB connector closely ,is it 0.8MM or 1MM ,sometimes its hard to tell. This model can have a problem if the bootloader gets corrupt.To solve it GPG2 has to be pulled high for the mirror function to work,see page 44 in the schematic ,after you moved the resistor attach the charger it will pull code from the EC in the bios but not all of it, then unplug charger,move resistor,attach JIG and then you should be able to program it fully.EDIT: not all chips support that mirror function.
