I've managed to extract the bios update from toshiba, got 2 pieces bin files.
1@pcs ME_FW bin
1@pcs Uefi image bin

The size ME_FW a litte few than 2mb. Flashing with your Prog, Probably it fullfilled automatically.
Uefi image contains ITE firmware at the Beginning of file.

Look the contents with HxD apps, Compare these file with yours. Only at Beginning file and End of file, if look similar then you can flash with those.
You must backup your dump first.
Make sure you have signal PLT_RST at pin 22 wifi connector and DDR3_DRAMRST# at pin 30 Slot RAM
Good luck



PS: Maybe you will got issue to extract it. Since Im using 7z 64 bit version

Hi meritosari,
Before i flash, PLT_RST was 3.37V & DDR3_DRAMRST was 1.347V But after i flash with your files the PLT_RST Was 0V & DDR3_DRAMRST was 1.347V. Is it ok.

Before is OK signal was good.
After definitely bad I think.
Probably wasn't bios issue.

I always trust Firmware/Bios from Official update IMO

ME_FW in Pegatron always make me confuse.
ME FW store in 2 MB chip separately from uefi image. On others mobo we always find the EC bios in smaller chips of mb (size2 mb).
But Pegatron do that opposite the thing.

May be wait for another good dump

Hi meritosari,
I found the problem. The problem is on RTD2132R chip. I replaced it from another spare board. I used your UEFI Bios dump and i used old ME_FW dump on it. Now the laptop working. Thanks for your help.
