How to upgrade ex-Verizon HTC m9 without a Verizon Sim card?

A

AC Question

I paid full price for my Verizon HTC m9 and left their service for different carrier. Now I can not upgrade my phone without a Verizon SIM card. And I can not get rid of their red Verizon screen when ever I turn ON my phone. Plus I can not get rid of Verizon apps.

Sounds like you should head over to XDA Developers and get rooting instructions. If you're not familiar with Android, rooting is how you get all that without service. Get rid of branding, unwanted apps, upgrade, downgrade, mix OS options all with root.
