Yes OC'ed my device, had it around 1.2ghz but also used it at 1.3ghz some time ago. Installed different versions of fastern9 without removing so overwrite. from old to new and other way around. So like I said, don't think it was due to fastern9 alone but a combination of different factors. Traysh, send me your address in DM, will provide you with a N9 (used one but should work just fine ;-)) so that you can further develop fastern9.
