Thanks I also found the bell black edition 4.2.2 MDJ was able to get me into the service menu. But, I am a little confused about the instructions. Mainly step 7. It says reenable SHA256, but it doesnt say how. I can go back to it in the menu, then select Perso SHA 256 ON, then am i done? Or do I have to restore the "Golden Backup" again to apply the changes?
Also step 3 was a little confusing, I dont konw why it says use *#9090# to access the hidden menu, because the guide step 3 links to says to use *#0011#. I pressed *#9090# but it just took me to some weird DIAG CONFIG menu which I didnt know what to do with.
Oh, also step 1 mentions downgrading the firmware to MDJ, which as kriEv mentioned cannot be done, only the modem, right?
Anyways, I am assuming its safe to ignore those last 2 parts i mentioned, its just step 7 i really need help with. How do i restore PERSO SHA256??
*#9090# and *#0011# are essentially the same thing. One works for some phones and not others. I got mine to work with *#9090#.
