Tutorial How to downgrade to iOS 12.1.1b3 from 12.1.3 and up

[Tjabooo 3.9k iPhone 12 17.1.1]

This is how you can downgrade your iOS device that's on iOS 12.1.3 or higher! Apple still has iOS 12.1.1b3 (which you can jailbreak) so it's possible to downgrade to that firmware and jailbreak your device. Now it will most likey (100%) get unsigned so this method will get patched. Now, I am not aware of any method to backup and restore your device without being forced to update. Since if you're on let's say iOS 12.1.4 and make a backup, it'll only be 'compatible' for 12.1.4 or higher and not lower. So keep in mind that you might want to store all your pictures on iCloud or somewhere were you later can download them and put them on your downgraded device. For ex. transfer all of your cameraroll to a folder on your computer where you later can restore them. Just a quick reminder  P.S. Read the whole tutorial before you start since you need to do different methods depending on your device!
 

Requirements: 

A computer (Windows/Mac)

I think DFU Mode is unnecessary. Normal mode and just hold SHIFT on your keyboard and click on update/restore should work, right? Or did they change that on latest iTunes?

I actually have no idea, I'll try it now and if it works I'll edit my topic then. But thanks for your note 😛

UPDATE: Nope, if it's turned on it asks for it to be turned off and when it's turned off it doesn't detect it

They must have changed something on the latest iTunes.

I tried without DFU. It works. Just click shift and update/restore. No issues. I clicked shift and restore. Createa backup before that
