What OS are you running, some will have older versions of uboot available in their repos that you can install and then write to the appropriate place (for example, iirc Manjaro has dated versions of uboot releases and at the end of the installation in terminal you'll be given the necessary command(s) to write the newly installed uboot

When I read this, it sounds like a cold boot works  ???
Reboot has always (or nearly so) been problematic, so why not just shutdown, then restart
dd commands,,... first run lsblk to know where to flash to, replace <emmc> with correct device
dd if=/dev/idbloader.img of=/dev/<emmc> seek=64
dd if=/dev/u-boot.itb of=/dev/<emmc> seek=16384  (or bs=1M seek=8,,, since 8*1024*2=16384)

The Kali installer does disable the Sdcard boot by default when you install it to the eMMC & the color bars are normal for the display after the initial boot-up screen; it doesn’t affect operation.

The PBP will not reboot & when you try, it’ll get stuck on a gray/colors screen similar to the start up one. You always need to power it off instead. (Reinstalling will not change it.)

If you want to modify your U-boot install, here is the complete guide:
https://docs.u-boot.org/en/latest/index.html

or you can build it from source & reinstall it fresh to try another OS:
https://docs.u-boot.org/en/latest/build/source.html

I haven’t had the CRC error on my PBP & it has various causes. If you want to run Kali on your PBP please follow this guide:
