If you have a new HiPad Pro or you know that your tablet is unlocked, please DO NOT Update OTA.
First make a boot.img backup for you and for all the community. This will help you to fix many issues on the tablet.
For instructions on how to create a boot.img backup use the follow tutorial LINK.
@mrfury I hope you don’t mind but I know you have better knowledge than me to support any user regarding this topic so I will tag you here :)!
Thank you for your time, and let’s hope to have an unlock boot.img sooner :)!
