How do I flash a custom kernel on Pixel 7

I built a custom kernel for my Pixel 7, to include the *NFS* kernel module. I'm struggling to flash this to my phone and get it loading. After I flash this to my phone, the Google text appears, but not the G animation that follows. It dies with the following message: > **Android Recovery** > > google/panther/panther > > 13/TQ1A.221205.011/9244662 > > user/release-keys > > Use volume up/down and power. > > Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on the device. > > - [x] Try again > - [ ] Factory data reset To recover from this I flashed the stock panther-tq1a.221205.011.zip/image-panther-tq1a.221205.011/boot.img back. The only thing I could find is where the boot log /sys/fs/pstore/console-ramoops-0 has the message: [ 11.517099] [E] [DPM] check header failed [ 11.517105] [E] [LNXDBG] vendor combined_checksum must be 0x62352e30 but 0x620d2e30 I thought this was related to *Android Verified Boot 2.0*. To test this out, I tried to flash the stock image and stock vbmeta.img, with AVBv2 disabled: $ fastboot flash --disable-verification vbmeta vbmeta.img This also surprisingly results in the above boot loop. To recover I have to flash vbmeta.img without this flag: $ fastboot flash vbmeta vbmeta.img I tried to patch vbmeta.img flags at offset 0x7B to be 3 (aka AVB_VBMETA_IMAGE_FLAGS_HASHTREE_DISABLED | AVB_VBMETA_IMAGE_FLAGS_VERIFICATION_DISABLED). I flashed this, and the same boot loop occured. My phone is rooted with *Magisk*.
