Downgrading from ios 16 to 15.5 cause phone to be stuck on apple logo screen

[AbhayAysola]

I tried downgrading my iPhone X from ios 16.0 to ios 15.5, the command ran without any errors but my phone is now stuck on a black screen with the apple logo (no spinner or progress bar). It's been like this for a few hours please help

Did you end up figuring it out? Having the same issue with 15.6 and no errors... I hope my phone's not bricked 💀

Update: won't show up in any of the idevice commands anymore 😭 I guess i should really get a android now since I was planning to already.

I don't remember exactly what I did but I think I just held the power and volume buttoms for a longer time (like 2 mins) and it worked

I just remember trying to get it working for a few hours and then suddenly it booted
