Sequoia not showing up on reboot

Hey y’all so I’m trying to run Sequoia on my mid 2014 15” MacBook Pro 4,4. Ive watched numerous YT videos on the process and I just can’t get my setup to follow all the steps.

Here’s what I’ve done:

Ran Time Machine to an external hard drive.

-Download OCLP.pkg 2.4.1

-Create macOS installer (Sequoia 15.7.5) and save to 32mb micro SD USB (formatted in EXFAT, USB drive shown in pics)

-Install OC to same USB drive

-Reboot and hold the option button

Here’s where it deviates…

When the system come back on I choose the EFI boot (icon doesn’t show an orange drive but shows a black hard drive connector) then when that opens it shows only a hard drive icon with Sequoia colored circle behind it but says BigSur below it.

I tried this process 10 times before just launching the Install macOS Sequoia app on my drive without the reboot

I then ran the root patch

Now in about this Mac is saying my macOS is Sequoia, my storage is BigSur, and my display is 47”. Comp is running super slow

Can I start over?

Is my USB just not compatible?
