Install KernelSU on Two Devices

I want both my Samsung Galaxy M30 and Redmi Note 8 Pro running Android 15 to boot with KernelSU so I can freely experiment with low-level tweaks and in-kernel modules during development sessions. To keep the test environment consistent I need the latest Android 15 build of the Infinity X custom ROM installed on each phone before the KernelSU patch is applied.

Scope of work
• Unlock the bootloader on each handset (Odin for the Samsung, fastboot/MIUI unlock for the Redmi).
• Flash Infinity X Android 15 and confirm a clean first boot.
• Integrate KernelSU into the appropriate kernels, flash them, then verify root access through adb shell and the KernelSU Manager app.
• Supply any patched images, recovery zips, or scripts you create so I can reproduce the setup later.

Acceptance criteria
– Both phones power up into Infinity X Android 15 with KernelSU fully active.
– adb, fastboot and (for the M30) download mode remain functional.
– No bootloops, encryption or Wi-Fi issues after 24 hours of normal use.
– A short step-by-step log of the commands and tools you used, including exact build numbers, is delivered alongside the patched images.
