Hi, I've realme 8 5G/Narzo 30 5G, the device is stuck in brom mode and i can see
OPLUS Preloaderin Device Manager, butmtk fails with following logs
Looks like realme/OPLUS has locked down brom completely on realmeUI4/ColorOS 13
The device uses MediaTek Dimensity 700 (MT6833) SoC, currently on stock Android T fw.
mtkclient used to work on Android R & S fw but it does not on T firmware now.
Would be huge help if you can look into that @bkerler . Thank you in advance
