Easy, device sends RID and unique data to sign, then wait to signed block back and verify it by public_key.

Not have anything good to make shoot.
Device disassembly require nothing, just remember about need start NOT from screen corner, but after it. Around sccreen corner plastic frame.

After remove screws will void warranty. You had been warned.

Remove battery connector, short TP, insert cable. After device connect - remove short.

BTW - seems as OPPO using/start using EFUSE to avoid downgrade - yes, like QLM! At first look :D

You can flash older SW preloader, it will enter in brom loop, until new version will not be flashed.

Without Battery, TP With Battery Always Risky, Maybe can Motherboard Short.

tia,
Every TP procedure is potentially dangerous.
So better not use, or use at own risk. Also, better use some resistor for better short circuit protection.
