got a hold of an old M8 needing an update, what is the safest way to move from 4.4.4 to 6.0 it's locked S-ON
Code:version: 0.5 (bootloader) version-bootloader: 3.16.0.0000 (bootloader) version-baseband: 0.89.20.0321 (bootloader) version-main: 1.55.605.2 (bootloader) version-misc: PVT SHIP S-ON (bootloader) product: m8_wlv (bootloader) cidnum: VZW__001 (bootloader) security: on
If you want to unlock the bootloader you are in luck as I do believe 4.4.4 on VZW M8 is compatible with Sunshine. It is $25, but worth every penny.
Are you looking to do this or no?
To answer your question, however, either way would be to run the RUU.
