.NET Forum / .NET Framework / Compact Framework / December 2006how to write a program which is able to survive after a hard reset in mobile device
Hello, I am researching the possibility of write a program which won't be earsed after a hard reset in mobile device. Can anyone point me a direction or give some advice? is it possilbe to do this using .net compact framework? or it can only be done in OS level? Thanks in advance The definition of a hard reset is to erase everything and return the device to a factory-shipped state, so unless your app is part of the factory-shipped state (i.e. in ROM) then no, you can't do it.

If you're not (and by the nature of you asking the question, it indicates you're not) then you can't.

By using our app to deploy, and storing our application data on the SD card, we can have our Hotline department execute a cold reset as part of their troubleshooting to rule user "tweaks" our of the possible issues. This can also be achieved by flash memory + some special post-boot procedures if your device supports it. For example I develop for symbol MC50, MC70, MC9000, VC5090 devices and all have a special built-in flash volume, which persists the hard reset or clean boot (on WM5) and the OS launches some predefined applications from the flash volume on hr/clean boot. I'm succesfully using this approach for one of our customer's system to reinstall all neccessary applications and libraries after HR... regards, Filip > Hello, I am researching the possibility of write a program which won't > be earsed after a hard reset in mobile device.
