Actually, you don't downgrade: You update to 9.0 or 9.2J, then downgrade system settings to 4.x via gateway menu. You can do this with any games in the list at 3dsdb.com when searching "9.0.0J" if you have that cart. If you have the gateway red+blue cards, you don't have to update at all, but otherwise...Well, actually i have CN JAP. How is working the downgrade? So basically i have this two choice (downgrade or update and wait eventually). Thanks for reply.
Are you sure? You can update your games with a cia installer like DevMenu or FBI, and if you wanted to buy a game to support it, you have the option to spoof eShop to gain access in your emulated up-to-date firmware (EmuNAND).Well actually i have an old 3ds with latest firmware (10.3) with ninjhax and i have also a skyblue. On the new 3ds i didn't install nothing at the moment.
I would like to keep the 3ds jap updated, cos i would like to update some jap games and buy also game on the eshop and try eventually (if happens) the new exploit on the old 3ds. I didn't expected to find a firmware so low on this new 3ds. Soo, now i'm just thinking about this options and make a decision.
