Chambie TV

Hey I'm a total noob and wanted to flash my TV box. I have the h96 max with the rk3318 4gb ram & 64rom. I got to point 6 where I should burn the image to mmcblk2 and then restart. and since then my tv box doesn't work anymore, I can't start the multitool either, the tv box doesn't start at all or from time to time it lights up blue and red. I really need help. https://share-your-photo.com/31f1a778cd https://postimg.cc/jWyRhjXP
