Why Am I Stuck At T-Mobile Flash Screen On S4 Boot-Up?

[Android Central Question]

My Samsung S4 boots up to the T-Mobile "4G-LTE" screen. This is normally the last screen before going into the regular home screen. I even get the little T-Mobile audio jingle. But whatever I do I can't get it past that last boot screen.

I have tried:

Soft reboot

Battery in and out

SIM card in and out

Memory card in and out

Battery fully charged and minimally charged

Plugged into power source

Unplugged

Plugged into computer

Download (Odin) mode

Recovery mode (wiped cache/did factory reset)

All to the same conclusion, It gets stuck on that last T-Mobile screen. I can't get into safe mode (different than Recovery or S/L mode?) , it just goes into Odin mode. When plugged into computer, doesn't boot far enough in any mode to register as a plugged in device on the computer, so I can't get to the phone internals.

Anything else I can try? Thanks!

Try to boot to safe mode.

Tried it, no joy. It just follows the same behavior as above: Goes to last TM splash screen and hangs.

That's too bad. Since your phone is worth under 100, you may want to get something up to date. There are good options for used unlocked s7 for around 150. S5 is going for 100.

Thanks. I decided to give Samsung a rest. I have an unlocked Pixel XL being delivered next week. I was just hoping to get at some of the info on the old phone.
