[Q] PLEASE HELP SOFT BRICK sch-i535 VERIZON
I recently installed the update 4.3 for my phone, which blocked the only thing I use the phone for free HOTSPOT. I tried to go back to 4.1.2 and obviously messed up somewhere along the way. Presently I can boot to download screen and recovery, but NOTHING works. Anything I try to install I get an error message. Currently, when I try to boot I get "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." Don't want to do that, since they already told me they will not revert back to previous software version.
I have Odin 3.09 installed, USB driver for my phone installed and downloaded multiple tar and md5 files that are the correct ones for my phone. When I try to install I get FAILED! every time. I am putting it in the PDA slot, with proper check marks.
Please help me, I will give additional details as you see fit, don't want to clog up the thread with everything I tried, like unlocking bootloader, installing custom recovery, etc.
I'll be here all day, hopefully I can get some quick responses.
