[T790W] Enable Modem Diag

[EnumC]

To backup your EFS & NVRAM or to modify band settings, you need to enable Qualcomm's modem diag port. This usually requires root, but it seems that there's a built in system app that allows you to toggle this capability directly.

To enable diag, enter ##3424# in the dialer, and press the "Diag port' checkbox in the popup. Then, you would need to install Android HS-USB Diagnostics AF2E driver, which is also attached below.
The phone should now show up under QPST, and you can dig around policyman in EFS explorer & also create xQCN backups.

Have fun!

Thanks, I'm thinking to buy the variant Revvl 5G, as I see the step you uploaded you can make backup EFS and NVRAM and then you can also rewrite, which means you can unlock to use sim card from other country.

Surely the group of unlock box as Sigma Box and others, should be working on the way to make it unlock on the network
