I made the transition today from Haxchi to tiramisu, then disabled update block, go to settings to update to 5.5.6, it begins updating for awhile then during update it shows the error code 162-4065, wont turn off so i have to eventually unplug, turn it back on and loads into the wii u menu fine(besides the annoying update required popup), load a virtual console title(gamecube) but now it shows the 9999 error.... I followed all the advice, followed steps to a T, but idk how to fix it and also when i hold x now on startup it doesnt load into the tiramisu menu thing. The damn subreddit is down too and there was tons of valuable information that i couldnt access. Been a rough day with this shit
