Official TCL/Alcatel service center is the first stop,
second one - should check if some box supports it.

Waaaaay too many stupid people today who fully erase
modern, secured, imei-signed phones ...
(without having secure partitions backup)

on any commercial box.

1. If phone was totaly erased, you will need one working phone,
to read single-file backup rom (from 0x0 to beginning of userdata area),
then write to phone, later edit proinfo to retail model,
and to again use MobileUpgrade

2. If you have security backup (nvcfg, nvdata, nvram, persist, pgpt, preloader, proinfo, protect1) - jsut edit proinfo to retail PID and use MobileUpgrade

If Mobile upgrade read device, but says "no greater version available",
and refuse to update - only factory flasher can flash it.
(remote/paid service, etc.)

If upgrade works, and phone power on after that, but there is no imei/sn,
means that nvram is signed and cant be replaced/fixed by upgrade tool.
In that case maybe can be tried with Pandora Box repair.

So, no one can guarantee success. I had one new TCL phone (TCL20Y),
but i didnt have time to play with erasing it and checking all of this.
I am writing this from experience with other brands,
that are all using signed nvram (imei/sn) on newer MTK models.

After all of this has been said, thats why I contstantly repeat,
from long time ago that "One must be very stupid to fully erase MTK phone without having a backup".


***EDIT: I have just checked ... looks like that device is offered
only as customized (operator) device, and that's why MobileUpgrade refuse to flash it.
Only solution (for not fully erased devices) - Factory tools (remote/paid service).

You can, however, try some of these PID's : (and see if MobileUpgrade will flash it)

T767H-2*LCEU12
T767H-2*LCWE12
T767H-2*LCE112
T767H-2*LCGB12
T767H-2*LCWEK2

T767H1-2*LCEU12
T767H1-2*LCWE12
T767H1-2*LCE112
T767H1-2*LCPH12
T767H1-2*LCMY12
T767H1-2*LCTH12
T767H1-2*LCTH22

T767H2-2*LCWE12
T767H2-2*LCGB12
T767H2-2*LCTN12
T767H2-2*LCEU12
T767H2-2*LCAP12

* = A, B, etc ...
Stay with same model pid (IE: if you have T767H-xxxxx, doint use H2 or H3 pid)

small note: Device need to have at least preloader and proinfo flashed inside,
so MobileUpgrade can work.
