Hi I recently purchased the novo 9 spark ii after I did a bit of research between similar models, this looks like a good bet based on using mainly for work purposes. I really like the tablet... But i have a few problems... The stock firmware needs upgrading... * i cannot get the keyboard to stop vibrating on keypress - this option has been disabled in the menu but still doesnt work * there are Chinese apps that cannot be uninstalled, when I reboot the tablet they are reinstalled. * there are a few performace upgrades which i assume will be met with a later firmware Please advise what is he latest, most appropriate UK firmware I can install without voiding my warranty. Please supply a download link also. Also any advise on rooms, I don't really want to install something that will void the warranty but again any advise is much appreciated guys Thanks!
