Tried to flash this and got stuck in bootloop so flashed 2.7 again. I'm using Corvus ROM 8.5.Hardrock kernel v3 changelogs:
- Build with latest proton clang 20200906
- Kernel Address Sanitizer updates (KASAN)
- other optimizations
- media related issues fixed for stock vendor roms
**Note please download stock vendor kernel having zip filename prefix with stock_*
Oops. My Bad. I had flashed stock_hardrockkernelv3.zip instead of Hardrockkernelv3.0.zip. Flashed correct file now.
