Programming MEC1663 on Lenovo X1 Carbon 7th Gen

[sikocan]

Hi team,

I'm going mental trying to figure this out and I need help as nothing makes sense.

I've wired up as follows following advise from SVOD Telegram group as they also said Schematics has a mistake and their wiring is wrong for JTAGs, originally I followed Schematics, it was also doing the same as below.
TP6 Ground
TP1 TMS
TP2 TCK
TP3 TDO
TP4 TDI
TAG_RST to C8706

I've also shifted the R8715 resistor to R8714 location.

SVOD says chip detected, but only reads 190K and it's all empty. Same with RTH809.

I've added 10k resistors to TP1 through TP4. Then removed it as it was not really needed. Also tried putting 50Ohms resistor for TP5 and run also tried running solder blob, no difference. Could anyone please shed a light on what I'm doing wrong?

Board: FX490 NM-B861

Thank you

Connection must be ok as svod detects it properly. What happens when you try to program it?

It reads a 190kb of 0s, empty, no data. I heard it should be higher kb and obviously have data.
