I modified the original bios 1.20.0 that i extraced from the dell website and flashed it now its working again...

Update: identical bin files on the ezp2019+ using 1.5mhz speed same as the ch341 bin files from the neoprogrammer software...

Hello,
I posted a topic in the troubleshooting about dell g15 ryzen5 edition that shows 2amber and 1white (possible processor failure) i suspect it could be a corrupt bios not sure though, i made multiple backups of the original bios winbond 74M12JWSIQ using ch341 and ezp2019+ (i desolderd the chip and used a socket and the 1.8v adapter)

i made 3 backups in neoprogrammer using ch341 and all 3 are identical and another 2 backups using ch341 v1.31 (ch341AFree) and the two are identical, however the size is different the bin files extracted with neoprogrammer are 16mb the other...

yes indeed i was mistaken the main bios is winbond 74M12JWSIQ after reading some topics related to it, it is identified as W25Q128FW [1.8V] so my main concern is that when powering on the laptop i should get 1.8v on pin8 of the bios also maybe for the gpu to get voltage the bios must post first?
So before desoldering the bios chip and program it should i check something else?...

Here are the pictures with resistance to ground readings and voltage after power on for all the coils it might interest anyone with same board looking for these readings
