Still not turning on.. No charging Led or any indicator.. im sure its bad bios programming though. Because its working fine prior except for admin password. :-(
Could it be because my RT809F is not capable of reading and writing the chip correctly?

I bet you read the chip with errors..write the bios chip back with the original bios and see what happens..

If there is a schematic and boardview available have a look around the chip for missing or dislodged resistors ,check carefully.

I guess I'ma just try to decap the chip tomorrow and look for the internal VCC pad lol
I’ve done this before on other damaged chips that come damaged but never did a WSON8

i was trying to remove BIOS chip and it is damaged same like yours. Can you help me on how can i read this chip or how to repair.
