A9LH is only installed to SysNAND, you can use the new Decrypt9 to restore your EmuNAND to SysNAND without erasing A9LH (which would require a reinstall on a O3DS or Brick a N3DS)
first, update Decrypt9 (download the new decrypt9 zip and copy the bin to /aurei/payloads/ and name it "default.bin")
then you will want to backup your current EmuNAND to "emuNAND_original.bin"
Copy and Paste from @Plailect's Guide
Enter Decrypt9
Copying RedNAND data to SysNAND
- Reboot, then open Decrypt9 from arm9loaderhax by holding L+R on boot
----------------
- Go to "SysNAND Options"
- Go to "SysNAND Backup/Restore..."
- Select "NAND Restore (keep a9lh)"
- Confirm and restore from emuNAND_original.bin
Once you do this, you will be on 10.7 (or whatever version your EmuNAND/RedNAND was on) SysNAND and have retained A9LH.
owh wait, so the dump ctrnand is not needed anymore ??
(the method you wrote seems easier, btw. i would like to ask why the usual process was like dumping both sys/emu and then injecting emu to sys "basically for the swap and then the wipe of emuNAND" but the sys nand into emuNAND partition< is that needed for those who would want emuNAND wiped completely?
let's say i want sysNAND only, can i use the method above you have posted?
simply dumping my emunand and then restoring it with the new d9 function to retain a9lh?
and if i wanted ds/gba compatibility ,then i assume i would have to dump/inject the twl agb etc. from emu to my sys yep?
