Soft bricked or even worse,need help asap topic

There is a longer story , but it is way too long
Short story: i had cyanogenmod, and i broke the lte and i was told to update the modem, i wasnt able to update the modem with cm , so i decided to update the modems with the original stock rom 4.2.2 , soi booted into recovery , and wiped everything including the dalvik , and then i proceded into donwload mode , but my phone would no show up in odin (because i forgot the antivirus and the firewall), so i only turned off the antivirus(forgot about the firewall), and because the only source of internet for my pc is the hotspot( i am using a different pc right now conected to comcast) i turned my phone on , and then i had to setup cyanogenmod once again, and then i looked up on the net why odin wasnt working , and i found out it was the firewall , so i put my phone into download mode ,without erasing the data , and i turn off the firewall , and i start the process of putting the stock rom on my phone , and it fails, and then i try to flash it again and again and again , and everytime it gets stuck when writing the image , as you can see from the odin log i posted under , so then i format the nand with odin , still not working , so then i try to Re-partition , and it kind of works , i can boot up into recovery mode, before that i couldn't , and it says that /mount , /data , and all other folders , have invalid arguments , btw i got the pit file from here ---> add a w before the dot and an m after co ww.droidviews.co/how-to-unbrick-your-bricked-samsung-galaxy-s4-gt-i9500-gt-i9505/ . so then i try to flash the rom again , and i get the same error , btw when i flash the pit file , odin says it passed , but my phone , says that the pit check failed, but the blue bar goes all the way. Please tell me if theres anything i can do to it.


here's the odin log for all the system flashes which failed, i didn't post the re-patition log because everytime i do it odin says it was a sucess , and it doesnt give me any errors , but when i go into recovery it says that all the "folders" : /mounts /data /cache ... are an invalid arguement.
