Quick question, I can install a tmo stock rom (oreo) to my phone (actually I use Verizon
All the US Note 9s are identical, so you can install any of the carrier U firmware on them. But why do you want to run T-Mo firmware on Verizon?
Actually I forgot the Note 8 has carrier switching firmware. All the carriers use the same exact firmware build. It will automatically switch carrier bloatware and featurws based upon the SIM card installed.
But my question remains...if you're on Verizon, why do you want T-Mo firmware?
