apologies, my intent was not to be disrepsectful.
my inital though it was all those were CE-based, hence the genuine ask.
Do you mean on a Fire Cube 2?
See 1st post on this thread.
PS7690/4716， is there any chance to root?
No, there’s only system user for firmware that new. That won’t boot CE.
I see someone ask if could try to downgrade firmware after get system user, but seems no significant progress yet.
Anti-rollback is enabled, downgrading the bootloader to a version that can be unlocked would hard brick the device. An unlock for PS7652 or newer firmware requires a new root exploit + new bootloader exploit.
Hey everyone, quick question. I’ve got a Fire TV 2nd Gen. I’m pretty sure I can’t downgrade the firmware anymore because I probably messed it up before. Right now, my only option is to swap the SOC over to a spare UGOOS board that doesn’t have one. Will this fix my broken UGOOS and let it decode FEL smoothly like it did before? Thanks a lot!
Already asked and answered
Cube 2 still seems like such an underrated, underappreciated (and IMHO better) Ugoos AM6B+ alternative :). Maybe preaching to the choir here… just did a video to show anyone hesitant to try rooting that it’s now pretty easy:
Better than AM6B+ 
Any plans on a guide to update from 21.3 to the new 22 builds? assuming they work?
they were already updated for 22, you’re just looking in the wrong place.
