Moved 'sudo cp boot/Image /boot/${FOLDER}/.' outside version checks, making the Image copy unconditional. Restore the copy into the appropriate JetPack-version branch or guard it with the same version conditional.

Details

✨ AI Reasoning
​The change moved the kernel Image copy (the command that copies boot/Image into /boot/${FOLDER}) out of the version-specific conditional and into unconditional execution. This alters control flow so the Image is always copied regardless of JETPACK_VERSION, potentially bypassing previous version-specific behavior. Such an unconditional action may have been unintended and can cause incorrect files to be installed on unsupported JetPack versions. The rest of the script logic and echoes remain unchanged; the only behavioral change introduced is the unconditional copy.

🔧 How do I fix it?
Remove debugging statements like console.log, debugger, dd(), or logic bypasses like || true. Keep legitimate logging for monitoring and error handling.

Remediation - low confidence
This patch mitigates the unconditional kernel Image copy bypass by restoring the command to execute only within the JetPack 6.x version conditional block.
