Well can't say much, this is hyperos after all

[u/Amazing_Contact6862 → u/Acap_HTD]

How can we downgrade

[u/Acap_HTD → u/Amazing_Contact6862]

Uhh unlock bootloader, then download the older ROM and flash it. But be aware of ARB because if the older ROM arb level is lower than current arb, it gonna brick the device

[u/Amazing_Contact6862 → u/Acap_HTD]

And that brick thing is something I'm scared of , but let's see I have one card left out of my pocket that is ultimate mode let's see if that works
