Virgin Mobile S4 stuck on boot Logo HELP

I'm not sure why i can't get it working but i was flashing back to stock rom. I have the correct rom and everything flashes fine on odin. I am unable to reboot to recovery. it says its loading and goes to black screen, and tries to boot to OS again. I tried flashing twrp with odin and same thing. I flashed the stock rom multiple times and it just won't boot. I even used Kies to flash it to stock rom and it was successful however stuck at boot logo again. The one thing i didnt do was wipe data/cache etc before flashing to stock rom but every tutorial i seen doesnt state to do it before the flash anyway. Has anyone ran into this problem before?
How are you able to get into download mode to flash rom but not be able to go into recovery? I had this issue once with my note 2 and went into recovery and wiped data and rebooted successfully....

Dear XDA Members
I have a Galaxy s4 GT-I9505 i had an old version of Omega Rom on my galaxy and everything was workin smooth. But i decided to flash a new rom and do a factory reset and delete all data then i flashed A modifyed stockrom with TWRP it was working fine until i restarted the phone and it stuck on the galaxy s4 Boot logo so i went to recovery and flashed it again with wipe/dalvik etc. I saw in TWRM the system was unmounted so i mounted it again. and flashed the same rom again. it was booting and after i was able to us the rom again until i restarted the phone and it stuck again
I then downloaded the Google stock rom for s4 and flashed it via TWRP after i could start the rom and could use it but when i restarted the phone it was stuck again on s4 boot logo. After dath i wiped and factory reseted many times and tried 3...4 other roms but i allways had the same problem.. i also tried an original stock rom via ODIN but this wont start at all. One thing i mentioned in TWRP under Mount it allways kiks out the System mount.
I tried to fix it for 8h now and cant find a way.. so i need Your help have you got any Idea what is wrong with my galaxy ?

[Q] Un-soft brick my s5

I was recently flashing a rom on my rooted Verizon S5 via Safestrap on one ROM slot. I flashed the rom then downloaded the 0A8 kernel. Upon bootup, the phone was stuck on a boot loop, but I can get into recovery and download mode. I have already tried to factory reset the phone via recovery and I have also tried to put on the stock kernel again. Both were unable to resolve the issue. I have a fulll nandroid backup so wiping anything would not be an issue, but is there any way to solve this problem?
Also, when the phone boots up, it stays on the S5 boot screen and you will hear the boot sound but it will remain at that screen for an infinite amount of time. Can anyone help?
Thanks!

Hi. I did the same mistake like a week ago. and the only fix is installing android 6.0.1 again is the only sollution.
Use Odin to reflash kernel or stock rom. If you have twrp flash another rom.

Hi, I have a 900T. I don't know if I have the same problem. I have 6.0.1, and got the boot loop. I reflashed it off of rapidgator, and it worked, but after I powered the phone down, it is stuck in the loop again, and reflashing doesn't work. Well, it sort of works, but when it loads onto the phone after success with Odin, it says "erasin" half way through and goes back to loop. I am a noob, so I am not sure what kernel or stock rom or twrp are. Thanks!

I tried 5.0 and it does the same thing. Success on Odin, phone restarts and starts to load the firmware, then it stops in the middle and resets to the boot loop. Is my phone hard bricked?
