Hi There
I have spent a few days researching and searching the net but I still haven't been able to find a solid answer to how you can create a hard reset resilient piece of software that is user installable rather than having to manually tweak extended roms etc.
I have a piece of inhouse software that is hard reset resilient on CE 4.2/5.0 devices but I need to port the application to some new WM5 & 6 devices and I am currently testing a few different models. I have looked at the excellent work in the Extended_Rom discussions on this forum and tweaking the config.txt and unlocking and adding my cab would be perfect for me apart from I need to do something that will do all of this on a simple user install. The user will install the cabs, the device will need to burn the app into the Extended Rom so that if the device is subsequently hard reset the software is still running.
I understand that I will have to write a different cab for different handsets (For slightly different reg settings), thats not a problem and using c# I am able to do most of this in a cab, but the questions I have are below:
1. Is extended_Rom a WM5 thing only or is it a device dependant thing? What do I do when there is no Extended_Rom, like with the Kaiser/TytnII? and is it a reliable method of doing this!?
2. Are the last 2 lines in the config.txt always the same (LOCK:Disabled
RST: Reset), so that I could reliably insert some extra CAB: lines ahead of them?
2. Is creating a RAMDisk a better option and is this something that would offer a more generic solution to me across all devices?
3. Is there a proper industry standard/MSDN way of doing this!?
There are pieces of software out there that are doing this like B2M mProdigy's device management client so it must be able to be done.
Any help or advice would be very much appreciated.
Regards
