Issue:

Issue:Nokia phones give error:
"ERR: CMT ALG Boot CERT MISM" or "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

Here is the underside of a SHU box, you can see the regulator is marked U6 very clear.

This one is a CM30A but same specs as a M30.
