After following this guide https://github.com/Plailect/Guide/wiki by @Plailect , I succeeded in installing the Luma3DS CFW on my 9.2 O3DS, I dont hold anyone on this forum accountable for my own action. I was under the impression that i would be able to play my games through the Gateway RED cart. but i was surprised to find out that there is no such thing. I copied GW4.0b files: arm9loaderhax.bin, Launcher and boot.3ds to root SD card and GW folder to /3ds. but all i was getting is black screen upon powering up the system. As it was mentioned in the guide, I have HBL.cia installed, so opening the HBL and clicking on the Plaisysupdater_v04 to downgrade my system from "sys. 11.0.0-33" (notice that CFW will say sys. instead of ver. ) to fw9.2. I clicked on Y than the screen stuck on "INIT HAX..." I have updates folder in the root of the SD card with Firmware 9.2 My questions: Has anyone succeeded in using GW red cart with Luma3DS? if so, can you please provide the steps that a noob like me can follow? How can i restore sysNAND_original.bin fw 9.2 back to my O3DS? I dont mind loosing A9LH.
