The install should of removed that webman icon in Portuguese, if the fan is running like webman then you should be able to open the settings menu. you can try it. move the one that's there to another place just in case, you need it, then use that boot text I put up. also try and make a prx one as well and copy the whats in the boot text to it. and put that in the same place.
Also what do the icons look like in the webman games folder when PSN Patch installs the plugin they should look like coloured PS3 default user icons. That's when you know its installed the plugin properly. then when you install the webMAN mod they will all have icons with the names in...PS3..PS2...PSone...BD and such.
Also you could look for the back up the mod made when you installed it PS34Kpro. Look in dev_hdd0/games/ find the folder for the app, it will be some where near the bottom, and look for a folder in it that's called backups. should be in folder USRDIR under apps. if its there then i can tell you how to do a manual restore of the xmb, as i am now getting baffled.
