It does not boot to any screen. HOWEVER, i can power it up into download mode.
So I tried reflashing some stock images for T-mobile, And it does not boot no matter what I do. It will power up into download mode only.
Recovery mode tries. Itll come up Recovery Booting... for a quick second then go away. But it never comes up. Tried letting go of the buttons at the blue text, etc.. no dice.
I tried erasing NVRAM on the factory image flash and it didnt change anything on the recovery either. tried flashing CWM to recovery, same deal.
Normal boot I get nothing. just a vibrate and black screen. no logos.
Download mode shows this:
Product Name: SBG-T999
Custom Binary Download: (Yes) 5
Current Binary: Custom
System Status: Official
Qualcomm Secureboot Enable
It did say Binary Official before I reflashed a kernel or some sorts for tmobile to see if it would boot. same thing.
Only thing I havent tried is bootchain, and I cannot find the bootchains for T-mobile. I also havent tried reparitioning as I cant find any info or PIT files for this device.
