[Q] Accidentally deleted my kindle fire OS topic

Hi, i accidentally deleted everything, including my OS while trying to restore my kindle to its original state. Your help would be appreciated!

-its stuck in the KF logo (white and orange, meaning original bootloader)
-I cannot access TWRP
-when i try to use KFU, it says ADB status: online ; boot status : unknown
-when i try to install TWRP via KFU, it gets stuck in " waiting for device" ( i guess i cant go into fastboot mode)
-i'm not accessible to a factory cable because im not from the us

Help me please

Thank you!
