I know I suggested that as a theoretical possibility, but it can't be just that by itself, because I have backed out to V9 and used the LG Software Updater to go to VC at least 9 times while writing the instructions to revert and answering questions afterwards. This was all with the same phone. It could be a component of a more involved reason, but not the sole reason.
Also the software updater reads the MEID of your phone as well and your new phone would have a different MEID. They can't assume that your phone has the update just because your phone # is the same as that logic could fail if you got a replacement phone.
True, in the tool I clicked "update history" it shows I had updated to VC. IDK, unless I think of something I am done for the night. I need sleep, lol. I will run this from another PC as well tomorrow. As of now I have the V9 radio on CM7 and it seems OK.
Thanks
Oh, did you do factory resets before/after nandroiding back, for prepping to use the LG Updater Tool?
