Here are the things I know:
The phone is trapped in a bootloop after the Cyanogenmod logo and restarts itself after a minute
It is S-ON but unlocked
It is the M7_UL T-Mobile model
It is on HBOOT 1.56
The Radio is on 4A.24.32.63.09
The OS 4.19.531.10
It can still enter recovery and is recognized by my PC
From what I've read that has been a little bit, I can restore it completely with a RUU (kind of like a .tar in ODIN for Samsung), but it has to be Relocked and in other sites it says that it has to be S-OFF, needless to say that I don't know what tools to use and then I've seen that that Hboot 1.65 is not supported and well right now I have to create my SQL project, sorry to ask you guys as I hate when other do it just to not read but I swear this is not the case.
Help to fix this will be very appreciated
First thing, try this
Force reboot: press and hold POWER + VOLDOWN (under a bright light, not kidding!!), after about 5 seconds or so buttons should start blinking, and after 30 seconds or so, the phone will reboot, let go of POWER, but keep holding VOLDOWN to get back to bootloader.
(you may need to try 2 or 3 times to get it right)
What recovery do you have?
CWM has problems with 4.4.2.
The rom bootloops
Install twrp 188.8.131.52
Make sure it's for your phone.
If that doesn't work, do you know how to post a fastboot getvar all.
