So!!! I Did all the steps to install A9LH, exact the same i used to mine and another friend. Everything was great, untill i was trying to launch arm11.bin. (Alredy in 2.1FW) But for some reason the Browser frozem\Crash and didnt work's. After reading, asking and reading. I tried everthing. Clean and reset browser delete and connect to another wifi spot. Nothing works. Someone said me to follow this guide : https://github.com/Plailect/Guide/wiki/3DS-Stuck-(2.1.0-Without-Functional-Browser) I read and read. I acess "http://www.3dsdb.com/" And find my Zelda OOT was 4.3U ( Websites says Rev01 ) it's 4.3U I follow instruções. Warning: Spoilers inside! Instructions Copy Launcher.dat from the Decrypt9WIP zip to the root of your SD card Copy your NAND backup to your SD card Launch your game cart which contains a 4.X update Accept the update when prompted Wait for it to reboot you Open the browser and go to http://www.reboot.ms/3ds/load.html?Launcher.dat If the exploit was successful, you will have booted into Decrypt9 Go to SysNAND File Options, then select NAND Restore Restore from sysNAND_original.bin But after updated my NEW 3DS wont boot anymore and shows the "Error Message: An Error Has Occurred. Hold Down the POWER Button." So i got lost. Did i something wrong? Maybe my Zelda ooT it's above 6.x? The website says 4.3U, but i dont know. What can i do guys? I have my NAND BACKUP and Emunand BACK and my emunand 2.1 unbriked. Hardmod only?
