My GW emunand was on 10.3 but upgraded to 11. Once on 11 the method of using the select key to access the GW rom selecter no longer worked. The only way I could think of to get back to 10.3 was to format Emunand and use sysupdater. However after formatting emunand I can not install HBL on 4.5 as i get the following message "hblauncher_loader v1.1 by yellos8. Getting system-version/system-info etc... Detected system-version: Old3ds 4.5.0-0 EUR Since the X button isn't pressed, this will now check for the otherapp payload on SD, with the following filepath:sdmc :/hblauncherloader_otherapp_payload_old-4-5-0-0-EUR.bin Requesting the actual payload url with http...
