Hacking [Question] Instal a9lh on CFW 9.2 emunand

[coco11]

Hi
Actually I have two New 3DS console one normal one XL. Both are downgraded from 10.3 and 10.6 to 9.2 and installed CFW rainand wint EMUnand (11.x.x.x).
Now I want to made some upgrade to A9LH with fast boot without emunand.
My questions:
1) what is curently the best option (safe nad fast for N3ds) to install a9lh in sysnand with upgrade to 11.2
Link to guide please. (I read something about OPTless but I don't know about this..)
2) Can I use my games instaled in emunand with save games to transfer to sysnand when I succefull upgraded to a9lh ?

Thanks in advanced

the guide

This contain all the answers.

• OPTless can brick (low rate but still, it's possible), so it's not in the guide anymore.
  sysnand a9lh has better boot rate and faster, and more protection on sysnand. If you re afraid of messing something up with sysnand, it's the best option. I think you can have both a9lh and emunand, I personally plan on adding a9lh to my 9.2 sysnand - 11.2 emunand if possible.
  Some will not see any interest in that, I see it like adding more protection.
• With the guide, you'll learn how to dump emunand to sysnand after a9lh upgrade.
  
  Edit: with OPTless, you could just downgrade 9.2 and install a9lh. In the guide, it will show you how to do with OPT (downgrade to 2.1 to get the OTP console, ...)

I read the guild but I can't find section: Downgrade to 2.1firmaware , instal al9h, updgrade to latest 11.2.. it is no transparently written guild..

2.1 CTRNAND flashin' to get the OTP needed (must be done for each console)
a9lh instal
upgrade to 11.2 with the nintendo upgrade system (in settings) after finishing the guide.

If I install (downgrade) system to 2.1.0 via CTRNAND can I reboot the system and start decryp9 and instal a9lh or I must do it in one time.

You should follow the guide in order. If you start jumping around and not doing precisely what the guide says you'll probably brick.

Still I don't know when file otp.bin will create ..

It doesn't matter. Just do what the guide says. If at some point the guide says "make sure your otp.bin got created" and yours didn't, THAT'S when you can start questioning what's going on.

Restore the original Health and safety apps dump (the one before fbi injection) with decrypt9.

Finish the guide, it tells you how to restore your H&S app

Restore the original Health and safety apps dump (the one before fbi injection) with decrypt9.

I deleted because I restored from Emunand... Can I use from another Console ?
