Tutorial Guide written by @xxlMVPlxx 😈

▫️Completely removes T-Mobile Apps and any underlying Software (there aren't a lot, but why not completely gone!)

▫️Use Dual Sim supported by the hardware & the ability to use other carriers.

▫️Get on the faster firmware release schedule of stock Global firmware because it doesn't need to be certified by T-Mobile, which are always generations behinds.

▫️You can now Root your OnePlus 7T & install Magisk & use Magisk Modules.

▫️You can OEM unlock your Bootloader & put TWRP & install Custom Roms if you like.

◽ Conversation will NOT change your Model Number it will remain a "HD1907"
