Root [Verizon] Help with Galaxy S3 on Verizon Prepaid wont start up due to wrong modem flash (I535PP)

Hello, i have installed a modem onto my GS3 using safestrap. i was trying to see if itd fix the 3G and wifi issue on the other rom slots (not stock but the other two slots i made) every rom i flashed i had no wifi or 3G. so i read around and tried flashing a modem on rom slot 1 (custom rom) and i tried to boot into system on custom rom even on stock and it bootloops into an error that says "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon wireless store for help." now i can get into safestrap to do any flashing or wiping and i can get into download mode. i just cant boot into any rom and i cant get into the stock recovery for any factory reset. Can someone please help me to getting my phone back up in running? Now i am running 4.3 on Verizon Prepaid. So instead of the device being SCH-I535 (Verizon) its SCH-I535PP (Verizon Prepaid) not sure if that means any difference but any help would be much appreciated!

UPDATE: i have been trying to flash the NC1 and ML1 firmwares using odin and always fails. i tried putting in the 32gb pit partition and it fails. so i went into safestrap and did a complete wipe of stock and now have no OS installed. tried installing the two firmwares again to see any changes and still failed. unfortunately, wiping the stock rom, removed my safestrap but i can still get into odin mode and stock recovery just fine. im out of ideas and am desperate for help. the side of the box that the phone came in (never updated it) says VZW-SKU SCH-I535MPP.
SW-VER. I535.NF1 and my phone said it was running 4.3. i tried the Verizon utility to repair at first and it always force closed at 83 percent. im out of ideas. can someone please help??

on a sidenote, i know this may seem off topic but if somehow my phone does start working again, how exactly can i get my 3G or wifi to work on any rom with safestrap? i already have tried installing the ML1 module with no luck. and i keep getting a pop up to insert a sim card but mine doesnt carry one. Just the sdcard slot. the roms were originally build from the sprint version but i am sure that i have the verizon side of it yet it asks for a sim card still. any help on this also would be greatly appreciated! and save me a big headache!

i dont give out my skype or social media things to people i dont know personally. sorry. as for the bootloader. i dont know what it is, all i know is i need a firmware that ends with NF1.
 
Okay when you boot into download. You wont get triangle. press volume to cancel and restart phone. Not continue to download mode. Which if you can use odin. You are there. Your phone is an sch-i535. Safestrap is our hero bit inherrntly unreliable in the VZ2-dsw world. You just have to check.your downloads and make sure you've done every step and keep trying til it happens. I had typed all my issues. But if I accidently hit my menu button on this forum iy kills my reply. Ive been where your at
any help anyone?? anyone??

Hello bjf18 , I hope that this can help. I went through the same issue...I tried everything , lots of tries with Odin , I made an image on my sd card with win32 disc imager , I tried a bootloader unlock code with Odin...nothing worked. Then I went onto a Verizon forum , and the very thing that hurt me , the Verizon update assistant , un-bricked my sch-i535. The update assistant has an option "Repair Assistant" I ran this as the instructions said ...connected my phone to my laptop , and unbelievably an hour or so later it finished , and my phone just booted up. I had almost given up...I was ready to do a JTAG. Also my phone was updated to 4.2.2 Kit Kat. Now that I have stock back , I am trying to figure out what I need to do to my Firmware , to Flash Cyanogenmod without bricking my phone again
