[Q] No IMEI / phone stuck on airplane - hboot 1.72 topic

Hi Guys

I'm lost in all the threads, I really don't know where to turn next.
I had a custom cyanogen rom and ended up flashing a nandroid to return to stock so now I'm with these settings:

ENDEAVOR PVT SHIP S-ON RL
HBOOT-1.72.0000
CPLD-None
MICROP - None
RADIO-5.1204.167.31
eMMC-bootmode: disabled
CPU-bootmode: disabled
HW Secure boot : enabled
MODEM PATH: OFF

Android version
4.1.1
Htc Sense version
4+
Software number
3.14.771.34
HTC SDK API level
4.63
HTC Extension version
HTCExtension_Sense45_1

Kernel version
3.1.10-g03b5369
root@abm032 #1
SMP PREEMPT
Baseband version
Unknown
Build number

The main issue is that I need to sim-unlock, and I get what I saw is not an uncommon issue (wifi bluetooth don't work, no sim is detected, seems to be stuck on airplane mode).

WHAT should I flash to get to a working stock version?
(I imagine there might already be an answer out there but I simply haven't found it up until this point, so any help is more than welcome)

Thanks
