I'm on AOKP Task650 4.4.3 (kitkat) ROM. Obviously the stock 4.1.1 SIM unlock method won't work on AOKP and I've read that the 4.3 version isn't able to downgrade and flash to a 4.1.1 ROM. What about 4.4.3? I also read that has to do with the bootloader and something about bootloaders with Knox on them won't work. I don't think that's my case.
When I go into my bootloader, I see:
Product Name: SGH-I747
Custom Binary Download: Yes (1 counts)
Current Binary: Custom
System Status: Custom
Qualcomm secureboot: Enable
So does that mean I can downgrade to 4.1.1 and unlock or am I SOL when it comes to unlocking?
Second part...if I can downgrade, do I have to do it via ODIN, or can I simply flask a ROM zip via TWRP?
If I have to do it via ODIN, can I perform a backup, flash 4.1.1, unlock, then go back into TWRP and restore to my 4.4.3 KitKat ROM?
