Hello, I am also facing the same issue on the Google Pixel 5 with redbull kernel.
If I use the default prebuilt kernel from the AOSP tree, I am able to flash and boot successfully. I was also having success with the factory image. However, when building a custom kernel using the android-msm-redbull-4.19-android11-qpr2 repo branch provided by this guide <https://source.android.com/setup/build/building-kernels>, I am stuck at the Google logo screen with the "waiting for any device" message: Here is my log: $ fastboot flashall -w -------------------------------------------- Bootloader Version...: r3-0.3-7051238 Baseband Version.....: g7250-00069-210128-B-7108850 Serial Number........: 11141FDD4001LG -------------------------------------------- Checking 'product' OKAY [ 0.070s] Setting current slot to 'a' OKAY [ 0.290s] Sending 'boot_a' (9324 KB) OKAY [ 0.412s] Writing 'boot_a' OKAY [ 0.324s] Sending 'dtbo_a' (16384 KB) OKAY [ 0.650s] Writing 'dtbo_a' OKAY [ 0.180s] Sending 'vbmeta_a' (8 KB) OKAY [ 0.140s] Writing 'vbmeta_a' OKAY [ 0.078s] Sending 'vbmeta_system_a' (4 KB) OKAY [ 0.140s] Writing 'vbmeta_system_a' OKAY [ 0.077s] Sending 'vendor_boot_a' (18844 KB) OKAY [ 0.670s] Writing 'vendor_boot_a' OKAY [ 0.120s] Rebooting into fastboot OKAY [ 0.070s] *< waiting for any device >* No changes have been made to the kernel. Would appreciate any advice.
