I had to purchase a physical flasher after I bricked it the second time.
You can also buy replacement chips because they just pull out and can be replaced by sellers on Ebay.
They are only a few pounds/dollars. Maybe but one for your motherboard first, then start flashing and messing around.
It might be ok, I just can’t test it myself and don’t want to cause any issues for you.
I used MMTool to insert the ReBar, UEFIPatcher to patch the bios, I then opened the patched bios in MMTool again and extracted all the patched items.
I then opened the unpatched bios, and inserted the items that were oatxhe into it.
I then ran ubu on it and saved it as flashback which created the Cap file.
It’s the last bit I am not sure about, I am not sure I I should have done the part that makes it a. .Cap extention.
I’ve only ever successfully done it with bin file.
Maybe someone else can clarify for us?
