CMT 2nd Boot CERT Mismatch

[viru]

Issue:
------
6233, 6234 Nokia phones give error:
"CMT 2nd Boot CERT Mismatch" on "Check" or "Flash"

Problem:
--------
Some UFS manufacturers used a National LP2951C M33 (3.3V) regulator, instead of a LP2951C M30 (3.0V) regulator (IC - U6)

Workaround:
-----------
Change regulator to LP2951C M30
