I know theres been tons of posts on this but i'm really stuck. Its a 74850c with the newest update. I'm using Blaster Ck3 with 3.3v switch mod on the probe. I have the key since I was the one who flashed it initially. it stopped writing after Bank 1 in the middle of the flash. Now it's status 0x7f and no device present. I've done erase,intro,dos and l-o-eras and even tried some probing tutorials to get to vendor. I've used different JF's all the way back to 1.7. Five days of reading and testing and still zip. This was problematic the other 2 times I flashed it. Should I just chuck it in the garbage and use a different drive(non-liteon)? Thnx for reading...
