Wink Downgrade bootloader from 4.3 to 4.1.2
I was successfully able to downgrade my bootloader using this method. I was on locked bootloader and firmware 4.3. After using this method i was able to flash 4.1.2 firmware.

Anyone able to downgrade from 4.4.2 locked bootloader?
Or any idea if the 4.3 file could work to downgrade from 4.4.2?

Okay, so I attempted this. My phone is opened right now as I speak. I held the tool, got a white screen, but the screen was on for 2 seconds, and then it booted into 4.4.2. I used the 4.1.2 i605.img file provided by the Original Poster of this thread.

Is it somehow possible that the bootloader was pre-unlocked from the i605.img and boots the 4.4.2 rom because it's not checking the signature? Or did it just fail and nothing has changed? I couldn't see any text, but then I couldn't see the screen all that well at the angle I was doing this at. I'd like to know what you think before i reassemble this phone.

I could reassemble and try to flash a recovery. If it boots custom recovery then I suppose i'm on a 4.1.2 bootloader. If not then I suppose it failed. Would like to know what you think of the white screen for 2 seconds. Do I need to try and keep the white screen on longer? I'm wondering if maybe the white screen was on from shorting but then slipped and it didn't finish? I have no idea.

Okay, I reassembled. Booted into 4.4.2. Flashed recovery. Then tried to boot into recovery. Got Verizon unauthorized error. Figured maybe signature problem Attempted to odin to 4.1.2. Same error. so I guess this method did not work on a 4.4.2 device. Only choice now is to odin back to 4.4.2.

Imo unless you can see what's going on with the screen you won't know if it works or not. Shorting the resistor can be hit or miss so you need to see if the writing came up on the screen
