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
You didn't mention what caused the brick as it can be a hardware issue, a damaged eMMC chip for example.

However, instead of flashing one file, you should try flashing ''repair'' files which are 4 flashable files you can load individually. These files contain the full set of Samsung firmware files. Inside these packages you will get PDA, AP, Modem, Phone, CP, BL, Bootloader, and CSC file.

Download theme from here and flash using Odin.

Fell free to ask if you encounter any problem.
