Very likely not.
And you asked this already, and the thread was locked for a reason: https://gbatemp.net/threads/will-coldboot-ever-be-possible.652552/
i ended up making the app. it took me a lot longer than expected because i decided to add a gui...although very basic.

theres no icon for the app atm (or even a name!) so feel free to send a pr if...
Take a look https://balika011.hu/switch/oled/
and no its not directly connected to the apu. Get a replacement and if thats the only short it should fix.
improve that, that´s the cause of your long glitchings time
you need to do it this way in order to have instant boot. A good ground points also helps. Clean as much as possible
Best regards
@SylverReZ, btw i already asked this a bit ago but you werent there so im asking it again. have you ever wore skirts before, and if you did, how does it feel?
