Hi, I also encounter the same issue. The build setup that I am using is as follows:
AOSP Build ID: RQ2A.210505.003 (Tag: android-11.0.0_r37) Kernel branch: android-msm-redbull-4.19-android11-qpr2 Build configuration: aosp_redfin-userdebug I got stuck at the "waiting for device" message after executing the "fastboot flashall -w" command. Then what I did was I copied all the *.ko files into the <aosp tree>/device/google/redbull_kernel folder. This step was able to overcome the error above and flash successfully. However, after flashing, the system tries to boot but it gets stuck at the "android" logo screen (this happens after the Google logo screen). Would appreciate some advice on this topic. Thanks!
