Does anyone have the bin file for this drive ?

 

Ok, I need help bad.
I must be doing something wrong since others have luck using mtkflash on Asus drives.
I have tried 3 different versions all the way to the newest and all of the different version bin files I could find.
I get is that it is not a identifiable type. some times using the a135 lock up, but will never do anything. I have tried several different commands to no avail even using sw instead of w.
Thanks in advance.
