I've got a ms28 that I can't get to flash.
I've tried the VCC Trick on an ICH5 and ICH6 motherboards with the same problem : I just can't dump the flash content ! Checked the solderings and they're 100% ok.
I've followed every lines in Textbook guide (which is very good btw) with no luck so far.
Using an iPrep'd USB key, the best I could get was to identify the serial device then mtkflash gets locked printing "Reading...00%" I then tried with dosflash with the same problem.
Timing seems really important too because in a 4 hour battle I could only get the serial chip identified a dozen times
Ms28 is powered using the xbox with the latest kernel (5787). Can this be related ?
I'm really lost and would really need some new ideas...
