Hacking HELP! N3DS stuck on 2.1.0

[3ds_tryinghard]

So I got a cherry looking N3DS on ebay for a solid price. I get all the way to installing a9lh after the 2.1.0 ctrtransfer. I open the browser page to 2xrsa and install launches (I've done this over 6 times now). The screen shows the nice, hit select to install, and guess what? Select button doesn't work.

I'm stuck with a unit without a functional select button on 2.1.0.

I would love some guidance on a way out of this. I contacted the guy who sold the unit but he's saying he's having trouble fixing the select button with firmware on 2.1 (since it's an N3DS lots of stuff are unstable.)

1. Is there a way to install a9lh without the Select trigger?
2. Is there a way to get to Decrypt9 on 2.1 so I can restore my NAND backup?
3. Is there a way to open Homebrew and see if I can trigger Decrypt9 from there?

What I've tried so far: Soundhax, doesn't work for 2.1, browserhax, crashes after yellow screen.

This is totally frustrating! Help!

-snip- never mind, didn't read it all clearly

He's lying when he says he can't fix the select button on 2.1.0. It's a hardware issue, not a software issue.

Was it advertised as having a broken button? If not, get your money back.

If you have a ds flashcart you should be able to boot into decrypt9 using mset

How will that help the OP install A9LH? And besides, I don't think MSET works on 2.1.0.

He said he was also open to suggestions to restore his nand backup.

But I agree, if someone has a better suggestion that will actually allow him to run the installer - then that is much better.

Here's plailects fork with Y subbing for SELECT.

It will still say SELECT but just press Y.

Is this the safea9lh installer? Because he doesn't have a9lh running yet.

Wow! How do I use this?

I'm assuming just rename the file "arm11.bin" and put that in the root of your SD card.
EDIT: Don't

Wait a minute. I gave you the wrong version.

From installer.c in the SafeA9LHInstaller repository:

if(isOtpless || pressed == BUTTON_SELECT) 
    installer();
if(pressed == BUTTON_START && ISA9LH)
    uninstaller();

Theoretically, all you'd need to do is just replace BUTTON_SELECT with BUTTON_A or something, compile the very minimally modified code, and run that. If you want to setup the build environment for this, you can. If not, I can't help you.

EDIT: Or you could use what zoogie attached above me...the choice is yours.

EDIT 2: This post assumes BUTTON_A exists...and I'm not sure if it does. In the event that it doesn't, you could simply switch the usage of BUTTON_SELECT and BUTTON_START.

There, attached.

Wow! Thanks! Again, should I just copy all of these to root and hit 2xrsa? Or should some files go into a9lh folder?

Just the arm9 arm11 files.

YES! It worked! Thanks everyone! You guys are the best!

Strike that. Strangely after installing a9lh select button seems to be working.
