Re: [Solved] #777 Network Data Failure (Codes 8 & 11)
This happened to me also when I flashed MR 3.23.10 release. I flashed back to VZW 6.5 stock.
I had same issue where no phone/text/data. I called VZW support (I got pushed up to lvl2 support). They had me go into the #778# menu and start updating a LOT of settings (NAM, SID, etc..). This allowed me to have phone/text as you indicated but still stupid 777 prompt/error.
I called back into VZW support and spoke to another lvl 2 tech and they told me they simply "sent a refresh" to my phone and I soft reset and had data again w/ no changes needed.
Good luck.
