Brand new phones are flooding the market now. There are lots of choices available, but I am stuck with Nokia E52 phone. It’s very handy and works akin to a smart phone. It has some Wi-Fi and 3G capability which is a basic thing required for internet connectivity. I could browse the internet with Opera Mobile browser and chat via Skype.
All the features are fine, but important VoIP software suddenly did not work after upgrade of firmware. Currently the software version is 091.003 and custom version 091.003.C00.01. Both software version and custom version were updated on 3 April 2012. The particular Nokia E52 model I have is E52-1 with type RM-469.
In dire need of the VoIP software to run on my phone has led me to search and try for a method to do a hard reset of the phone. I need the phone to be set back to the very initial state from the factory.
A way I discovered to format Nokia E52 phone was to use the following key combination:
*#7370#
I backed up first the phone contacts, messages, photos, music, videos and other data with OVI sync. Next, I’ve removed the phones micro SD card. After which, I used the above key combination to format the phone.
It sure did format the phones memory card, but the problem I have with downgrading or resetting the Nokia E52 software firmware still remain. The above key combination to hard reset or phone format did not downgrade the software firmware.
