How do I downgrade from IOS 15.5 back to 15.4?
3 weeks ago I updated my ipad to 15.5 and ever since I am experiencing software crashes every few 30 minutes and needed to be force restart every time, one time it was stuck in black screen when I boot it back up and had to be restored using itunes. I've gotten white screen of death, black, red, blue, yellow and green, no idea what any of them means. Any help is appreciated, thanks.
iPad mini 4, iPadOS 15
