Another repair center has soldered this AUO chip (AUO-11101-R1) , I'm not sure that pin 1 on the motherboard matches pin 1 on the chip. I have not found any datasheet.

Hi,
So i've bough a ch341 programmer, and the chip was CH341B . the test clamp was not working( when connecting bios using test clamp, ch341 device was disconnecting) I tried soldering the bios on the provided board, soldering the bios I could read the chip but could not write or erase. ASprogrammer , neo, ch341a programmer... all programmer software was hanging and device was disconnecting after few second of erase/write operating.
So then I have soldered a capacitor(whatever I had..[10v ~470uf ] ) from VCC to GND on my provided pcb where you solder the bios

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -
Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.
The BIOS...
