How to unbrick a samsung galaxy S5 (Softbricked no hardware keys)?

So the phone is a S5 SM-G900P, it is stuck in the Sprint logo when booting and the volume keys are broken (power and home keys work).

Developer mode and adb weren't activated in the phone previously

What I have tried:

• adb (doesn't recognize my device)


• bought a JIG that gets me to the download mode screen


• I have flashed 3 official firmwares using odin (
  G900PVPS3CQD1_G900PSPT3CQD1_G900PVPS3CQD1_HOME.tar
  .md5
  G900PVPS3CQC1_G900PSPT3CQC1_G900PVPS3CQC1_HOME.tar
  .md5
  G900PVPU3BOK4_G900PSPT3BOK4_G900PVPU3BOK4_HOME.tar .md5).


• Tried flashing TWRP recovery via odin so i could do the factory reset without pressing keys, it gave me a pass and i was hoping that it took me to that screen after that but same story getting stuck

All the flashing goes smoothly, but like i said gets stuck in the sprint logo
on all 3

I've read that going into recovery mode and wiping dalvik cache and cache plus factory reset fixes the stuck in carrier logo screen, but with no volume keys i can't access recovery mode.

So i'd love to hear any input or any ways you guys come across that can help me

Much appreaciated
