But if you killed card, did they fixed it within warranty?
Dual Bios cards I have only Sapphire Nitros nothing else, I have here like 10 different models, and only Nitro have dual bios...
1st CASE - I bought "like new" Aorus XTR 8GB card, its LED was not working and somebody played with timings already. As it has no bios switch I am not able to return it back to original bios without somebody sending me original BIOS for this card. Its LED is not working but it is not mechanicaly broken or unplugged as if I restart PC it flashes for half second. Or do you have any idea how or where to fix that LED settings?
2nd CASE - I bought new Gigabyte G1 8GB, my pc frozen while flashing BIOS via atiflash. Now card is a ZOMBIE. No PC turn on while that card is connected. I wanted to access its BIOS and reset it but I cannot cause that cooler is sticking too hard and without removing cooler I cannot access screws which hold the backplate. Got it? So that card is dead and I probably cant reset BIOS any other way yes? Need to send it back for warranty?
How to prevent this crazy atiflash from frozing my pc? It happened already 2 times from 24 cards I have, I have 2 zombie cards ffs, it is rly retarded. Why it works 22 times with no problem and two times crashes/freez and this is it, zombo cards...
The LED is user adjustable.. if the previous owner changed timings it is very likely he disabled the LED as well. Did your card arrive with the aorus graphics engine software cd? i found it made my system act funny but you can set the color of the led's, pattern of the flash/pulse and whether you want it on at all. install that software and you will be able to turn the LED back on provided it will work with the adjusted strap.
your default straps for aorus rx series hynix ram are:

I personally would not use a daily usage computer to flash cards, particularly if you're using windows due to unknown malware or virus or even just extra services you may be unaware of running on your system.
try to have an old box with free pci slot you can boot freedos to and flash from there if possible.
as for your ZOMBIE card i'm still at a loss as to what you're trying to do. there is no jumper on the pcb to reset bios although that would be a nice option even on dual boot equipped cards.
"access" the bios has nothing to do with tearing down a card or removing it's cooler. you should be able to revive it somehow if you search around and find a similar scenario to what you are experiencing.
