Known issues:
*#7370# is not working properly with this SW release
Resetting the device and formatting C-drive with *#7370# is not working properly with this SW release and can result to unstable operation of the device. It is not recommended to use *#7370# at any situation. In case reset and C-drive format is really wanted, it can be done by holding down green dial key, star (*) key and number three (3) key, when switching the device on from power key. Hold down all three keys until Nokia welcome animation is showed.
NSU update can cause device to reset randomly when updating to this SW release
NSU update can cause the device to randomly reset after the update. Switching the device off manually from power button will recover the device from the problem. The problem is caused by DRAM corruption in final boot during the update. This doesn’t affect the SW update itself and after manual reboot device works fine.
