@Sapricot,I attempted to flash the modified F9i (0xEA one) today but the computer didn’t come back after restarting. It just boot cycles without ever reaching bios and the backup bios doesn’t come on.
Since you guys do all this flashing I was hoping maybe you have some trick I can try to get it to boot. I’ve tried resetting cmos and force restarting, and desperately removed everything except cpu and ram and plugged monitor into motherboard hdmi but it hasn’t made a difference.
I was on F7 before if that makes any difference.
Sorry to hear about the problem and apologies for not making it known that BIOS F8 or F9i (which have the new GUI) must be installed first. I have modified the post accordingly, and to be safe, stated that official version of F9i should be installed first.
In your case, please see the manual for the process of initiating a BIOS flashback -- or contact Gigabyte Tech Support via the Gigabyte website. If BIOS flashback is not possible, it may be necessary to use an external SPI Flash ROM reader/writer to reprogram the BIOS chip. We can use a Raspberry Pi or 3.3V CH341a programmer for this. I can provide the binary file that will need to be flashed. But before going down this path, let's see if you can trigger BIOS flashback.
I have modified the post to say that BIOS F9i (official version) must be installed first. Then we can install the modified F9i on top.
This is actually my handiwork! :) The first one is conditionally injected in Mojave only and supports product names up to iMac19,1. The second one is conditionally injected in Catalina and Big Sur, and supports product names up to iMac20,2. It uses newer Xcode framework that does not work in...
