LAL5 REPLACEMENT BOARD. NOT THE MATEKF405BT TMMRC F4 BT. REALLY HAVING TROUBLE HERE

[dripstyle]

SO MY LAL 5 HAS BEEN MY BREAD AND BUTTER FOR A WHILE NOW ,HAD THE TUNE DAMN NEAR PERFECT. HAD THE EACHINE AND CADDX DIALED INTO CRYSTAL VISION, WELL THE OTHER NIGHT I CRASHED AND SOMETHING HAPPEND TO MY FC, IT WONT EVEN BE RECOGNIZED BY BETAFLIGHT, BUT I HAD ORDERED WHAT WAS SUPPOSSED TO BE A DIRECT REPLACEMENT AHWILE BACK BECAUSE THEY WERE LIKE 30$ AND I THOOUGHT WELL JUST THE FACT  THAT IS HAS INTEGRATED BLUETOOTH MAKES IT WORTH THAT. BUT ANYWAY I DID THE INSTALL wired exactly like the diagram.,BUT ONLY PUT POWER TO IT THROUGH USB.. SUPRISINGLY   the fc was even half ass setup in bf, but i am not getting power to my vtx  or my rx , i have not tried connecting the battery as im scared i may fry the fc. 
i know the motor pinout is different from this fc to the last and i have never remapped motors but i was going to give it a shot but in motors tab it gives me a 100%  ERROR warning that esc values may be incorrect. i dont havE ALOT OF EXPERIENCE WITH 4.2 AND THAT IS  WHAT THIS FC HAS ON  IT MY ORIGINAL LAL FC HAD 4.01
I HAVE SEARCHED UP AND DOWN FOR A REALISTIC PINOUT OR VIDEO OF SOMEONE SWAPPING THIS FC OUT WITH THE OLD ONE AND SEING WHAT THEY HAD TO DO DIFFERENT.  IT SEEMS TO BE A MELO F4 WITHOUT THE BLACKBOX. ITS MARKETED ON BANGOOD AS THE DIRECT REPLACEMENT BOARD FOR LAL 5 220 AND 228MM 
I CANNOT FIND ANYTHING HELPFUL I HAVE REACHED OUT TO BANGGOOD WHO JUST SAYS TAKE A PICTURE AND THEN NEVER REPLIES. I AM GETTING FRUSTRATED BECAUSE I DONT KINOW IF IT IS SOMETHING IN MY 4 IN 1 ESC THAT CAUSED THE DAMAGE TO THE LAST CONTROLLER OR,. SHOULD I JUST CHUCH THIS CHEPO BOARD OUT THE WINDOW AND BUY AN AIO 6S FC. ANY SUGGESTIONS ON BOTH TOPICS WOULD BE SO MUCH APPRECIATED.` WOULD THE F722 AIO 35A  BE ENOUGH FOR THESE MOTORS REALISTLY?
