Reset Userlocks on CM2MT2 needed

[yurais]

I have got some old CPU phones, MT6580, etc, which can be now bypassed with new SLA Auth bypass method and would like to just reset a Pattern Lock or user code without really wiping the whole thing up

any chance to enable UserLocs Reset button only for old legacy line ?

CM2MTK 1.58 cant be used, as this one has not SLA Bypass...

Just try memory tool.
Backup usr data partition.
Wipe and re-write backup with memory tool.
It helped me mostly on oppo phones for media data

Interesting Idea but too late

Will give it a try next time.
