m fastboot (check)
stock file (you have to use one = to or higher than the one currently installed. so 404 is a no)
flash manually (open a command prompt where you have mfastboot saved, connect your phone in fastboot, also make sure you have all of your stock files in the same dir as mfastboot, flash each partition using the mfastboot command and your correct file name. it would be easier if you look at the win batch file file in my gpt script for the proper commands to send rather than me trying to explain it. you will send the commands exactly as i have them in the batch file only correcting for file names and wait for each to finish, make sure its finished some take a bit of time like system.)
gpt utility (check)
step 1 or 2 (some people are lazy (not you obviously

and wont go find mfastboot, so i only mentioned it is in my script for convenience)
what 926 files (just delete everything but the mfastboot.exe and the batch file file. all the other files you wont need or can use.
if you want, i can quickly upload the batch file file so you dont have to dl all that just for one file, and you can get the mfastboot from the other thread you posted.
