@BlackMesa123 for his TWRP work on the Galaxy A54 and his help adapting it to the S9 FE . Without his device tree and Kernel, there would be no TWRP nor decryption for the Galaxy Tab S9 FE.

@Rainbow_Dash for giving us (ArchVisions and myself) the will to start working on TWRP for the Galaxy Tab S9 FE, and his guidance on how to do it. Also thanks for his patience while ArchVisions and I were using his thread for the S9 FE purpose.

@ArchVisions for his prebuilt kernel and his tremendous help (almost an addiction 😜) while testing the builds. He took all the risks testing this recovery!
