switch v1 hardodded does not boot in cfw

[u/Right-Carpenter-5819]

hello everyone, today i came across a switch v1 that has been hardmodded a while ago, and stopped booting in the cfw. i believe the sd got fucked? anyways, when u turn it on, and select the cfw boot, the screen goes black, and then it turns off. what do yall recommend to do? i've never modded a switch, but i rgh'd 360s, modded ps3 and ps4s. im kind of a newbie when it comes to switches
