Closed S8 Bootloop. Cant get past Warning! on download mode

[Alf0nz]

My device: SM-G950N SKT
OEM Unlocked
Tried to flash TWRP, Odin says Pass, now Im unable to boot as Im stuck at the Samsung S8 splash screen. Cant get into recovery, and in download mode, Im stuck at the Warning! screen. Somehow my vol+ and vol- arent working everytime I get into the Warning! screen. Im unable to flash stock firmware to fix my device. Any ideas would be highly appreciated. Thank you

volume rocker is working fine. I can get into download mode using Vol-, Power and Bixby. Once in download mode, even Vol- doesnt work to cancel. Ano po ung software na un? Hindi kasi ma detect sa PC ung phone ko kasi stuck cya sa splash screen na Samsung Galaxy S8

Pwede pa check kung anong Bit number ng firmware nainstall mo, as well yung firmware information sa download mode. Nasa taas iyun.

I coconfirm kung exactly ng nasa firmware mo na iattempt mong iflash.

bootloader ung dahilan bat nagloload ka sa recovery, downloadmode at OS mo once na ma hardbrick nayan malabo na maayos

USB Jig kailangan mo.. Search mo sa Google "Samsung USB Jig"

Siniguro mo bang nasa 80% ang charge ng battery mo bago ka mag flash ng rom? sa pagkakaalam ko requirements yan sa galaxy series phone ayon sa software documentation
