I just Un-Rooted by doing a manual USB update to the stock version of 2012.01.26 but it didn't replace the GTVHacker splash. System info shows a legit build so I'm pretty sure it's no longer running the unsigned kernal. There's a problem with my NSZ-GT1 stuttering when it plays back mkv files with DTS so I need to return it to where I bought it. I need to get rid of the GTVHacker splash before I return it. I'd update to the current firmware but of course if I do and it doesn't replace the splash then I won't be able to re-root and will be doubly screwed. Can anybody tell me if going to 2012.02.22 will replace the splash?
