I'm on 5.4.0 and just found out that I can firmware spoof. So I hop on over to wupinstaller.com and read the instructions very thoroughly (basically throw the update files onto the SD card and boot up the website on the browser). The problem here is, once I load up the website, the console hangs. I did this a few times (and will try a few more times), but every attempt leads to a hang. Am I somehow not reading the instructions right? Or I'm just being too hasty here?
