ok guys let me clearify things lol
you dont HAVE to unroot to update, i just didn't think it was possible to get it on any of the current custom roms..
BUT you SHOULD be on zve if your gonna flash roms for zve.. just common sense lol
but anyways, i discovered a possible work around for flashing #2 (ZVD) over ZVE.. which also comes to play in the whole updating to zve prior to flashing thing..
in the new zve base there are a few extra files for use with the radio updates.. so we could possibly include these files into the old rom base(s) to make them work..
one i can assure yiou is important is the folder lte_images found in system/etc..
i had to create and extra line of permissions for it to get data working on new rom because i was using an old script.. so maybe adding the files & permissions to #2 it could work?
but i wont be able to confirm if they will work properly with the old zvd framework, and again it most likely will only work on a device updated to zve already.. the baseband version is related to your service i believe.. and the baseband is not something you can change in a rom, it is outside the system directory on our devices
so there still much work to be done and things to be tested before we can just spit out roms lol, but i assure you im doing what i can.. i provided you all with a simple zve base to tinker with to get started lol
