I'm sorry my first post is me immediately asking for help, but I believe I have a bricked my ultra hdmi with a firmware upgrade. After spending the last two hours searching the web and not finding much on the topic other than a reddit post from almost a month ago with no information, I found this forum and figured I'd try my luck here.
Sometime last year I bought a pre-modded N64 with ultra hdmi (FW 1.07) online and it was just glorious. Today I found out there was a FW update and that I could use my Neverdrive for that. I read the documentation (rn_fw.pdf) and copied the file over the the SD card and ran it. I got far enough that it would say "validating data" and I got up from the floor to sit on my couch. I managed to sit down on my remote which turned my TV off. I turned it on again immediately, but the N64 would not produce any signal over HDMI.
Not wanting to brick the ultra hdmi I waited for 15 minutes before turning the N64 off and on again. The documentation said the flash would only take about 6 minutes, but I just wanted to make super sure.
Apparently this was not good enough or the TV turning off messed with the flashing process somehow.
Anyway, I don't get a signal over HDMI now. I can see a brief flicker when turning the N64 on, but the TV goes straight back to "No Signal". The N64 itself seems fine however as it still outputs a charmingly blurry composite signal.
The documentation says that the unit would have to be "serviced" in case of a bad flash, but it does not go into detail. Is there any way to recover from a failed upgrade? If so, are there any shops that offer repair services for this kind of problem?
Thanks in advance for any pointers.
