Hello guys,

If i downgrade my sysnand (9.0.0) to 8.1.0, create emunand (8.1.0) and then restore my sysnand back to 9.0.0, can i use sx os on my emunand? Is it possible?

or you could just create an 9.0 sysnand and downgrade using chooijodo whatever its called. you will still are required to boot using autorcm or something like that.

No because as soon as you launch the SX payload it looks for the CFW files for SX and they dont work with 9.0 yet.

Also read the PSA in my signature before you even attempt a downgrade.

Thanks for the PSA. Maybe just gonna wait for sx os to be updated to fully support 9.0.0

just make an emunand with sx on 9.0 fw and use it with kosmos for downgrade your emunand to 8.1, dont do anything on your sysnand, keep it 9.0
after your emunand become 8.1 ypu should use sx os with it

I think you must have not thought your reply through. He asked about loading SX on 8.1 not 9.0.

This is the best course of action.
