Unlocking bands for NA usage

[Samuelah]

Finally,, it worked though I struggled a lot to enable "VOLTE provisioned" switch from *#*#4636#*#* I had to force volte provisioning through ADB from here

Quick question, just modified some of the NV memory on a dual sim phone (Xiaomi MI5S) , and in result my first sim does not work anymore (found out almost a year later when trying out two sims at once).
Stupidly enough cannot find the backup I made before editing.
Trying to figure out if this is reversible damage or hardware damage: I've tried flashing stock firmware, stock rom, but the issue didn't change: Sim 1 has an IMEI in the settings, but no other sim info can be seen.
However, does this actually change the NV configuration, or is this memory only editable using QXDM, and is otherwise factory-set/not affected by firmware/rom installs?

Fastboot/EDL

If you not have saved qcn for restore don't panic!
For mi a2 lite fastboot flash firmware reflash original qcn .
If for other model phone fastboot reflash no work just go to flash in EDL mode !

Will this work for other Snapdragon 625 device, like the Lenovo P2?
