Hey XDA,

I want to downgrade my verizon s3 to 4.1.2 from 4.3 in order to flash a custom rom (that isn't TW based so I can't use safestrap). I did a google search and found this link:

androidpit[ENTER DOTCOM HERE]/how-to-downgrade-galaxy-s3

I have heard that trying to downgrade will trip Knox and your phone will be bricked. So basically my question is would this work..

**also my contract is about to end, once it ends will Verizon have to unlock my boot loader?

That link had been posted in this forum before. It is for the international version of the s3. It will not work on the Verizon version and will brick your phone. You cannot downgrade the Verizon s3 from 4.3 or higher.

No, Verizon does not have to unlock your bootloader when your contract ends. They have to SIM unlock your phone so it can be used on other carriers. Wrong unlock.

Ok, well there has been a 4.4 update OTA that I haven't taken yet. I know I can easily root if I took it. Has there been any success with flashing roms on that firmware or is it the same verizon garbage and I should just stay on 4.3 because I am more likely to get a boot loader unlock/solution to this issue.

(I'm about ready to sell this phone and buy an at&t phone I have had enough with verizon's overpriced non-service.)

The 4.4.2 update is also locked down. Pretty much no chance of getting bootloader unlocked on 4.3 or 4.4. If you want to run a custom ROM, you will have to stick with 4.3 and use safestrap to run a custom 4.3 touchwiz ROM. No AOSP, and no custom kernels for you.
