I must apologize for my poor language skills at first, I am not a native English speaker. Two days ago, I cracked my New 3DS (system version is 9.1) by following the tutorial which I found on the internet, in order to run the .cia games that I downloaded from the internet. The tutorial looks like this: Trigger the Browserhax to enter the Homebrew Launcher; Run Themehax_Installer from the Homebrew Launcher to install Themehax; Restart to Homebrew Launcher by trigger the Themehax; Run the Pasta CFW Loader from Homebrew Launcher to do : install Devmenu cia in HBL/FBI; install Cubic Ninja cia in Devmenu; scan a QRcode in Cubic Ninja to enter the Gateway Menu(launcher.dat); Backup system nand in Gateway Menu; Backup SD card on computer; Format emuNand in Gateway Menu; Restore the SD card backup on computer。Initialize 3DS system; Install Themehax again on the new initialized system; Run Boot Manager in HBL and open Rxtools; load into emuNand system in Rxtools; update emuNand system to 9.5 by install .cia-s; Install cia games with devmenu and play them. In the first a few hours when these jobs just get done, the 3DS works well with the cia games. But now, I can not load into any CFW such as Pasta , RxTools, Cakes, I just get a black screen again and again, and I have to force it to shutdown by holding the power button again and again. The 3DS original system, the Homebrew launcher and the BootManager is still accessible. Before it broken, I only installed a AGB_FIRM Signature Patcher in order to play Dsiware .cia games, it did't work. I have tried to recover it by anyway I can, such as check if system version bigger then 9.2(no, still 9.1), initialize 3DS, format/replace SD card... still get black screen when try to load any CFW. I already searched all the internet, did not found any case like this been reported. Looks like I am the only person who encountered this problem. anyone any idea?
