Hacking [Question] How do I uninstall A9LH?

[BurningDesire]

Here are the steps that come to mind:

1. Open Hourglass9
2. restore Nandmin (the guides stock 9.2.0 back up) to emunand
3. Open Decrypt9 on the new 9.2.0 emunand
4. Restore Sysnand to Nandmin (Without A9LH)
5. A9LH is gone? On stock firmware? Can now boot without SD card?

Are these the correct steps?

install a backup that didn't have a9lh

I know that. I am asking if the process I listed would be the correct one.

You can do that with A9LH.

I'm aware of that. Which is why I was hesitant to make that a point.

Why bother with the emunand thing? Decrypt9 can be booted straight from a9lh.

What key is it binded to for startup?

why remove a9lh?

why remove a9lh?

Because I wanna learn the full process, Installing to uninstalling to re installing.

check the Luma payloads folder. I believe Plailect's guide sets you up with it so it should be in there.

RESTORE A 9.2 backup before removing it k? Bc if you dont, you are gonna fuck up

All that's there is the start hourglass 9 payload

So put the decrypt9 payload in there. Luma's github info tells you how to bind a payload to a key but it may be obvious already.

So like this? but renamed to x_NAME.bin

Yep, just stick "x_" at the front of the name to map it to x on boot.

I advise making backups of the NAND with a9lh and also the OTP before uninstalling a9lh.

okay so i got it to boot. All I need to do now is restore Sysnand with Nandmin correct? (After making another backup ofc)
