Doesnt techpowerup.com have forums? Should ask there since it was their guide.

If you don't have a dual BIOS switch and you cannot boot up from the card, remove the card from your system, install it in a 2nd PCIe slot and install a working card in the first slot. You can then boot up from the first card. After you boot up, you can install the drivers for the 1st video card but not for the one that you just attempted to modify the BIOS on. Do not reboot if requested. Now follow steps 10-13 using the "original.bin" BIOS you saved and using "1" in place of "0" for the commands you type. The "1" is so that the 2nd card is flashed and not the 1st card which is not the one you wish to flash. Be very careful to use "1"s and not "0"s this time, because the card is no longer in the 1st PCIe slot.

Going to get a bit preachy here, but it's a lesson you seem to need. Feel free to disregard or not even read if you've already learned your lesson and aren't going to do this again.

I would very strongly recommend being much more careful in the future when you're following highly technical instructions that can potentially brick expensive electronics. You should have looked for the switch before you attempted this and killed your card. You should also have done a lot more research beforehand, it seems.

Always read the instructions entirely before you start, and look for problems people have. It takes about thirty seconds on Google (or simply reading some of the thread for the guide you linked) to find dozens of horror stories from people screwing this up and bricking their cards, as well as mentions of the numerous cards which don't have the switch. There's also a guide out there specifically for cards without switches, which you obviously didn't find or follow.

This is tricky stuff, don't just assume you can pull it off without trying. Recipe for disaster, as you've found out. Also, I'm going to go out on a limb and guess English isn't your first language.

I've really got to question the logic behind the decision to follow highly technical instructions in a language you don't speak that well. I could certainly muddle may way through a Spanish conversation with some strange looks and frustrated native speakers, but you'd never see me following Spanish instructions to make unofficial modifications to computer hardware. Misunderstanding a single word can be the difference between getting it right and getting a brick.

There were 2 things you did not read on that guide, or chose to ignore. That guide was written for reference models only, and it had a bios switch in the instructions, both of which does not pertain to you.

There are other instructions that can potentially work for you, but I'd advise against it as you already made a mistake following instructions, and most cards just don't unlock these days, anyway.
