Downgrade a jailbroken kindle from 5.16.21
Hi. I have managed to successfully jailbreak my kindle paperwhite 11th gen which was on 5.16.2.1.1 version and installed Kual and KOreader, but it got updated to 5.16.21 overnight as I mistakenly didn’t install ota update block. Kual fails to launch now but as the device is still jailbroken, is there any chance of downgrading it to the previous version of 5.16.2.1.1 to install koreader again?
