ok, so i've copied the full readouts (they were all by SysCheck ME v2.5.0) and as a bonus i've included my Wii U's older SysCheck from a few months ago when i began modding/updating these consoles, so it looks like ModMii did spot the lack of 248 and 249-251 being outdated, and i must've installed the new wads, yet for whatever reason the descriptions (Trucha Bug, USB 2.0, etc.) don't match his (or most people's i see lol).

i first hacked this Wii U's vWii ages ago, i think using SSBB, then updated it a few years back following Wii Hacks Guide (which would be this SysCheck right above), and now i was going through ModMii. is it a problem that it doesn't show 'USB 2.0' after those ios.. or the fact i don't have 'ES Identify' under ios248, but rather on 236, which ModMii recommends i Stub because, as i understand, it's no longer used/needed anymore?

Friend of mine did some testing and aside from version # differences 248-251 are identical, so unable to replicate your differences, maybe this was a one off?

@everyone UWUVCI's been updated to ModMii's FOSS version of Zesty's UWUVCI v3.201.1 using a custom build script I just shared publicly at https://github.com/modmii/UWUVCI

I wasn't planning on making it public but Zesty and at least one other person felt strongly that I should, so as of today it is :)
Click to expand...
UWUVCI Updated to v3.201.2 - FOSS (Free and Open Source Software version)
- This was a quick fix. It looks like *someone* deliberately tried to break every patch.

Latest FOSS version of UWUVCI can be retrieved from ModMii or directly from here

who knows, but thanks @XFlak and @jeannotte for taking a look. as long as it's not causing problems i wont worry about it, and i guess same with IOS236, or do you recommend i go ahead and stub (then remove) it?

sorry for necroposting.. but I need help. I was trying to mod/homebrew my wii for the first time and I genuinely don't know what to do. I followed all the steps, (except for the convert to MBR part cause I was suspicious) but the Letterbomb icon didn't show when I went to yesterday's log. can someone please help me?

also forgot to mention that I'm using a USB Flash Drive with about 100+ GB storage, sorry about that.

here's what it looks like on my flash drive. I don't know if it's supposed to look like this, but I swear the guide said it was supposed to look like what it displayed.
