[Q] Samsun Galaxy s4 sph-l720t wont boot - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I tried to root my s4 using the auto-root method. It now will not boot past the boot screen. I had the device encrypted, so i thought that had something to do with the problem and tried to go into recovery mode to factory reset my phone. When i tried to go into recovery mode it would not work and tried to boot normally and then black screened after i typed the password to decrypt the device as it did before. Any solutions?

[Q]Rogers Galaxy S4 stuck at boot logo

After flashing some ROM, I am having trouble because the phone is stuck in Samsung Galaxy IV logo.
First couple times I was able to boot to twrp and do a format, wipe, flash, then davik wipe. The problem is that I was able to restart and set up and update etc but if i restart the phone, it would stuck at boot logo.
So I flashed it again and installed GooManager and installed twrp again, tried to restart and it would just stuck at Samsung boot logo, I can't even get into recovery mode.
I tried using Odin and flash cwm but it would not boot into recovery mode.
Does anyone have any suggestions?
I'll try to flash it with stock ROM with ODIN going into download mode, but somehow I don't think that will work.
I'm using Canadian Rogers Galaxy S4 SGH-I337M
Please let me know if there is anything I can do
Boot to download mode (volume down+ home during boot) and Odin to stock MDJ firmware would be my suggestion. Give it a boot and then factory reset. If hangs on first boot, go into recovery (volume up+ home during boot) and factory reset via recovery. After phone boots install triangle away, reset counter, and then do the OTA update.
Finally got around to updating to the MG1 firmware last night and found that Odin directly to MG1 did not update the modem (baseband) and also left me with no Wi-Fi. The above steps applied the new modem and did not cause any Wi-Fi issues.
After update, to root just use the CF auto root for Canadian models with Odin then goo manager for custom recovery (twrp).

[Help] Not rebooting after successful flashing (Odin)

Hi,
I have a Samsung J5 Prime (SG570M) that is stuck in download mode. I flashed the stock rom with Odin (both last version) and when the flashing ends, it says 'successful' in Odin, but when the phone reboots it doesn't boot up, the screen remains black. The samsung logo doesn't even appear. Any suggestion what could it be or what should I do? I have done this a few times and followed all steps, and already tried changing PC, USB port and cables. I don't know what else to do or what I'm doing wrong.
Any help would be awesome, thanks in advance!
Are you able to enter recovery mode and wipe the cache?
Thanks again for answering
No, I'm not able to enter recovery neither. Tried every possible button combination :/
