Just going to provide some updates here. I upgraded myself to a T48 programmer. To test the programmer I worked on a different laptop with locked bios. An HP zBook 15u G5. It's really close to a G6 but has Winbond BIOS and EC chips vs the G6 I'm stuck on. Getting good contact on the chips with my 6x8 probe was a bit more challenging than expected but with the speed of the T48 it only took 2 or 3 read/verifies to get a good capture. Ran RC Unlocker on the EC chips 16mb file and programmed it back to the EC. Put the G5 back together and the unit came right up unlocked no problem.

So...

I've had really good luck with the CH341A Black. You'll need a WSON8 6x8 "pogo" probe if you don't desolder the chip. Use NeoProgrammer with the CH341 on the FZ-55D. Be aware you'll need completely remove the motherboard to read the chip on the back of the mother board. Panasonic did not make this easy (on purpose) but it's not too difficult....

Something is up, just attempting to make the reads corrupted the BIOS and bricked it.
For some reason when I connected to the BIOS chip the power led on the laptop's mother board starts blinking. Not something I'm used to seeing when working on these zBooks.
Not sure what I'm doing wrong here or if I have my CH341 configured incorrectly? It's been pretty solid even fixing 2 other zBooks a few days ago.
The usual challenges for me are getting the right contact on the chips and picking the right programming software. Neoprogrammer 2.xx has seemed to working great for me on the...

Ran into an issue where I can't get my CH341 and WSON pogo pin connector to read the chip using NeoProgrammer. It's the same board/chip as alfanikos displays in this thread. Just completed removing the passwords on 2 other HP laptops so I know everything was working fine, but they were all Winbond chips.
Wondering if I'm missing something here on this MX chip or is it just a dodgy connection with my pogo connector? I did notice the solder joints are a bit more "round" so that might just be the issue.
