[Android Q&A, Help & Troubleshooting] StormSeeker1:
Guys, I was finally able to read Non-Volatile memory values using freezex's secret code for enable debugging, installing the USB drivers that popup when you choose on the phone the USB option "Drivers CD-ROM" after connecting it to the PC, using "QPST Configuration" tool and "QXDM" tool.

I tried to replace the initial value "2251799813754906" with "68787503589", which, according to my understanding, should cover all Italian LTE bands (please confirm and let me know if there is a way to reverse lookup code 2251799813754906 to see what bands are included inside of it).

The value I entered persisted after reboot and I was able to read the new value with QXDM.

Unfortunately I'm still seeing only a 3G icon on the notification bar...any idea on the cause of this behavior, guys?

A lot of values are there, can you please let me know if changing any of those values might help unlocking the bootloader?

PAY ATTENTION: After having enabled Diagnostic Mode (with freezex's secret code), Windows Device Manager recognizes the phone as "ALCATEL HS-USB Diagnostics 903A (COM6)"; does the fact that it comes from Alcatel give us any hint on what to do?

Also, people, do you find any free space not used by any partition to try NEC Terrain trick?

Here's some information I took from my PVG100:

I was able to push the "parted" utility to the phone, after having found a version already compiled for ARMv8 processors (and the Qualcomm SnapDragon 435 inside the PVG100 is an ARMv8).

This is the output I get:
