Flash PM25LD020

[Oscar Ferrer Miralles]

Hi, good evening.
I’m trying to collect as much info as i can about flashing the “PM25LD020” eeprom. 
I read the info of your website but I need a litle help. I’m trying to flash the eeprom without desoldering from the pcb. The eeprom is the bios of my RX570 gpu that i bricked up last week.

Now the questions: In your support chips there is PM25LD020(C), it’s the same as mine?

First I’m goint to program in a blank chip and if Works I’ll do in the soldered chip. For the soldered chip I need to put something in –programmer?
I read for NVIDIA cards I need to put   <<–programmer gfxnvidia>> but my card is AMD i need to put <←programmer  ogp_spi>> or something?

I’ll program wit a CH314A.

If you need more info please send me an e-mail asking whatever you need.

Thank you very much.

PS: If you know, could you say me if can be compatibple an PM25LV020 and PM25LD020? Because if that is posible to change in the GPU pcb maybe I can bring back to live the GPU (But this is the last option).

Hi
I have tested the "Pm25LD020(C)" in February 2018 with an external
programmer.
Chip works and is fully supported.
I can not say if this chip is the same as your "Pm25LD020".

Also not sure if direct flashing is possible.
You can try to flash with an external programmer without desoldering.
Sometimes it works.
