[Q] Accidentally erased my Kindle Fire (1st Gen) OS topic

Hi guys, so I was going to give my old KF to my nephew as a gift. It was rooted, with TWRP and had CM10. So i tried to restore it to its original state (unrooted with the stock KF ROM). After I flashed it back to the original OS, I wiped the cache, the dalvik and the system using TWRP and accidentally deleted my OS. Now, when i boot it, it remains at the KF logo (white and orange so it means it has the stock bootloader). I also cant access TWRP ( i guess i've deleted FFF as well ). i would be so greatful if anyone could help me. i'm also a noob so if you could please tell me step by step on how to fix my KF.

also
-im not from the US so I dont have the factory cable
-when i try to use the KFU, it says ADB Status: Online ; Boot Status: Unknown
-when i try to install TWRP or FFF via KFU, it stops at "waiting for device"

Thank you! :)
