libreelec 7.0.3 –> 8.0.0 problems

im having trouble upgrading my chromebox with libreelec from v7.0.3 (jarvis) to v8.0.0 (krypton). whether i am going through the libreelec settings or downloading from the libreelec website i get the same results. the chromebox would upgrade to v8.0.0 but after the libreelec logo it would just stay black and nothing would happen. when i try to downgrade it always tells me something is wrong with the file. only after about 10 times would it finally downgrade back to v7.0.3. is there something im doing wrong? or is this a problem with v8.0.0?
