4.27 for treble?Update!
Until otherwise noted, Flash Kernel is not compatible with Open Beta 13 due to lack of kernel source for the Treble changes. I am not going to support Treble until OnePlus pushes kernel source, which can be found here. Once a new commit has been pushed so I can see the full changes, I will look into supporting it. If for some reason you fail to read both this post and the changelog in Kernel Manager for Franco Kernel, the zip will fail to install if it detects Treble.
Remember any and all bug reports need to include logs and clear steps to reproduce (see the info in the OP). You should also know what version it started with. If you want to be a tester and get builds before they are released here or just hangout, feel free to stop by Telegram!
- Merge Qualcomm updates (LA.UM.6.2.r1-09300-sdm660.0)
- Memory allocation overflow protection (kernel hardening feature)
Remember it can be auto-flashed with Kernel Manager for Franco Kernel!
