[cuthroat1]

ok last night i tried to upgrade to 1.5.1 so i did the whole process as i did when i first flashed it with 1.5 i followed the guide and everything went alright except when i did the read part it say invaild key i figured that because it it just read the custom 1.5 firmware then i just went to the flash part flashed it and now my drive wont read any disc i still have my original bin file so what do i do next i want to replace it to stock form and then start over

It sounds like you flashed the stock 1.51 firmware. You need to download the newest version of JungleFlasher (or really older versions will work just as well). Then, click Load Source firmware (open your old firmware with your original key) and click Open Target firmware (stock ix151-benq.bin). Click spoof source to target and save your file. Flash this newly created firmware.
