Hi. Thanks for the feedback.
"This SIM card is from an unknown source." is a problem with all Verizon ROMs.
It can be easily fixed

About the WiFi and other stuff, maybe it woun't work with CA-201L. The ROM was made for C811.
My Hardware version is 1.1, and I see yours is 0.3.
The only thing that I think might help is installing all partitions from C811 to CA-201L (currently in zip there are only updated ones)
I will post a ZIP with rest of images after I receive them so you can try it on CA-201L.
