So I bought an unlocked sprint g8 off of ebay but switched to another carrier called mint (uses t-mobile network) so I'm not sure how the software updates work. I'm aware I won't be getting updates from sprint, but I know that I have gotten 1 or 2 updates from lg since I got it. I'm a little confused as to if the updates from lg are all I need or if they are just security patches, and if there is a way to install sprint updates anyway.
I know I can solve this by unlocking the bootloader and installing custom roms once they start coming out, and on sprint I can enable oem unlock, but there is no way to access fast boot. If I do adb reboot-bootloader (or whatever the command is) it just does a normal restart. If I'm not wrong I should be able to do the bootloader unlock after lg adds the g8 to their supported devices, but I don't know how I'll be able to do this without accessing the fastboot. Recovery mode seems to be incomplete too (I can't use adb in recovery I think the drivers are not installed yet), so I think part of the sprint firmware is still kind of in a beta. So if the not being able to access fastboot and an incomplete recovery mode is a problem with the sprint firmware, will the lg updates themselves be able to solve this? Or is there anything else I'm completely missing?
Sorry if that was a little confusing but any answers would be great!
