[T-Mobile, Samsung Galaxy SIII] gsantiag:
Stuck :(

Hello. I really need help. I followed the steps from this tutorial: http://xdaforums.com/showthread.php?t=1840030 but I’m still stuck. First I had my Verizon Samsung GS3 rooted with 4.1.2. Everything was working just fine. The update 4.3 came out and I used Voodoo to keep my root on my phone. When the phone rebooted my root was gone but the superuser was still installed for some reason but I wasn’t able to use it. I went to root back to 4.1.2 and after ODIN was done and it said it “Passed”, when the phone boots I get the message: "System software not authorized by Verizon Wireless has been found on your phone... Please turn off phone and to Verizon Wireless store for help". I rebooted the phone in download mode again then selected cancel like some other people have done with the same problem but I get the same message. When I try to flash the “VRALEC bootchain” it gets to the part when it says: "NAND Write Start! Then it says FAIL! (Auth) All threads completed. (Succeeded 0 / failed 1). On the phone screen it says:”SW REV CHECK FAIL: Fused 1.Binary 0”. I tried the second bootloader that I downloaded the file named: BOOTLOADER_I535VRALF2_618049_REV09_user_low_ship.tar.md5”. It also fails. I used the md5 file checker to make sure the all the md5 files were good and they all passed with the correct signatures. No luck trying to flash the bootchains. I then tried to flash the “stock.vzw_root66.tar” with the “Auto reboot, F. Reset time and NAN erase all” selected. It goes through the whole cycle and it even says on the phone in blue: “ERASING USERDATA PARTITION”. The flash on Odin completes with no problems, but when the phone auto reboots, once again I get the: "System software not authorized by Verizon Wireless has been found on your phone... Please turn off phone and to Verizon Wireless store for help”. I rebooted the phone in recovery mode. I did the “wipe data/factory reset” and “wipe cache partition” then reboot the phone again. Once again I get the: "System software not authorized by Verizon Wireless has been found on your phone... Please turn off phone and to Verizon Wireless store for help". I also tried Hero’s bootloader unlock using “Root.66” and the pit file: “sch-i535-16gb.pit” except the part of updating the VRALHD baseband since I can’t even flash CWM. It passes but when it boots still get the "System software not authorized by Verizon Wireless has been found on your phone... Please turn off phone and to Verizon Wireless store for help” message again. I’ve tried flashing CWM and when it goes into the”NAND Write Start!!” It shows “FAIL! (Auth)”. I get the same error trying to flash TWRP. Even flashing the stock ROM 4.1.2 I get the "System software not authorized by Verizon Wireless has been found on your phone... Please turn off phone and to Verizon Wireless store for help”. I’ve tried to install .zip files from the “apply update from external storage” but then it gets as far as “Verifying update package… and then it goes into “E: signature verification failed. Installation aborted”. I tried h311sdr0id’s method flashing “BOOTLOADER_I535VRALF2_618049_REV09_user_low_ship.tar.md5” and it also fails. I am using the USB cord that came with the phone. I’m running Windows 8.1 but also tried using Windows 7. Any help would be appreciated. Thanks.
