Hacking Got a big brick problem

[Psychoticgamer92]

Okay fellas I got a big problem. My system was on 6.1.0 i had a backup of it and all boot0/1 and full nand. Then the system was updated to 6.2.0. I tried to restore, I restored boot0/1 no problem then tried to restore nand. Got error size didnt match. Now switch is bricked on black screen. Where can I get a boot0/1 for 6.2.0 if possible to see if that fixes the problem? I can access RCM mode but no cfw launches either. My guess is I restored a potential boot0/1 from 6.1.0 on a switch with 6.2.0 firmware. I just want a working switch I've tried a few things to no avail please help and thanks in advance!
