I cannot get this to work. I must be missing incredibly simple, and thus stupid on my part.
I changed the permissions for the HiddenMenu file so that the new "ON" version of the file would be saved. I shut down the phone and restarted it. I went back in and verified the file was changed and saved (it now has today's date).
If I go into the dialer and enter the code above, it does not enter service mode.
What the hell am I doing wrong?
EDIT: Got it. I tried a battery pull and that did it. For some reason a shutdown and restart didn't get it done.
B4 was already enabled.
