my biggest passion is to run a custom firmware on as many devices as possible
Nice hacking challenge of a way over-engineered "Smart-device"!
Inside we can find 4 SoC's from 4 companies:
Heat control via STM32F031
Input button via PIC18F8..
Wifi via ESP32
Main FW Renesas 400Mhz ARM A9

But something is strange this claimed unknown PAR2860 SoC(If that is really inside the ring) looks very much like the firmware of the 7 Segment Ring (DA14585 SoC) but is still different.
maybe a cloned DA14585?

Full custom firmware goes Brrrrr
These chinese vendors like Realtek Bluetrum and Jieli only care about copy protection and cribble down a perfectly fine ARM Core with their tooling🙄

AB5682B BLE SoC used in the cheap headsets and other BLE hardware🥳
This Bluetrum Chip series is ugly 😅 Debug via 1 Wire UART and a somewhat secured proto
This code now runs from RAM since we next need a loader to dump an write to Flash

Glitched and fully Dumped MSP430F417 in a non destructive way
Doing a Read data CMD and glitching the check if the password was entered we can dump 240bytes at once
By dumping the pass(vector) area we can read the full flash after one glitch
