Hacking 3Down - CTRNAND Downgrade

[ultimatetemper]

Could this be used to downgrade a recent A9LH installation to 11.2 to be able to do the A9LH-GW dualboot?

yes thats what it is for, but you don't downgrade a9lh you transfer your CTRNAND.

Thank you so much.
I can finally install A9LH now.
BTW, I have a O3DS, will the files on 3Down work for me?

sadly no. I have no access to an o3ds to dump transferable ctrnands, and also no one has opened issues on github linking those, until I am able to grab o3ds images you will have to use sysupdater or wait I think.

By doing this you lose your friend list. Am I wrong?

yes, but if you want to make 100% sure nothing happens you can backup your friendsave.bin and inject it afterwards, I don't know why everyone is asking this stuff, you all already did a ctrtransfer!

Most people restore their NAND backup after doing all the CTR transfers from the guide so they don't notice.

oh yeah, right, now that you say it, I should probably add bkup+restore friendsave.bin!

How can I delete this black icon? I have tried by looking into data settings, but nothing appears there.

thats a bad ticket, run tiksweep to remove unused tickets.

thats why you backup everything before doing changes to your NAND.

--------------------- MERGED ---------------------------

Update: added friendsave.bin dump + inject to prevent eventual loss of friendlists.

I did the backup, but the icon still appeared.

run tiksweep, probably one of your restored tickets was corrupted.

I have run tiksweep, it has deleted a lot of tickets but the black icon is still there D:

check if you have any titles installed to nand and remove them
You should be able to locate one title id in your sysnand that does not belong there. Once isolated, delete it using FBI.

11.2 and 11.4 are not fully uploaded.

How can I do that?

(FBI->Titles and check everything.)

I'm not sure why you think torrent [or magnet] links circumvents the Forum rules here...

Anyway - on topic this is just an 11.3 ctrnand - alternatively you just downgrade the 6/7 titles [or how many it is] that were upgraded, right?

If you had a 11.2-U ctr image, I would totally use this to make my N3DS GW-compatible again.
