[Q] Downgrade boot loader 4.3
I flashed t889UVALJ1 to phone using TWRP. When I use Android tool kit (show information command) it shows build T889UVALJ1 and boot loader T889UVUCMK7 which version 4.3.
When I reboot the phone it stops at the Samsung logo. I assume that the boot loader will not allow a system other than 4.3. How do I downgrade to a pre 4.3 boot loader?
Is there a way to get around and finish booting T889UVALJ1 (I want to unlock phone)?
