please help! S4 soft brick?

hi,
my S4 i9500 won't boot.
i have tried loading several versions of stock roms, recoveries and non-stock roms.
all stock roms fail in odin, and i get "unsupported dev_type" error on the device.
other non-stock roms install with no error, but the device won't boot after reboot.
finally, out of frustration and recklessness, i guess i used an S4 boot loader fix wihch loaded successfully from odin.
unfoutunatly, after rebooting the device, boot message sais GT-I9505 instead of GT-I9500. turns out it was a 9505 boot loader fix. :(
is there anything i can do to bring my device back to life??
currently, device won't boot to recovery (blue "recovery booting" on top left corner of screen), won't boot to system, but can enter download mode, and be identified by odin.
thanks!!

Find a 9500 recovery, flash that, wipe cache, factory reset, then try to get it replaced.

already tried that, both cwm and twrp. both won't load, and still i get gt-i9505 on boot screen

i found the problem. its my pc
i tried on another pc, and manged to load stock rom on the device.
could be driver problem, will check and update soon, thanks for the help guys!
