how to retain private data on master reset

[prabhu_a]

I have created a data file in my process private directory( \private\sid)
When I execute master Reset on my device, private directory remains but data file is whipped out. How do I retain my data file and its contents on master reset?

i donot think you can retain any data when you master reset the phone.

AFIK only pre-installed application will retain its data file on master reset and other applications data files will whipped out.

My .exe is included on the device Rom Image. I cannot retain my data file in private area even then?

In that case you may succeed in surviving *#7780#, the same way as other data survives. However the necessary API and documentation is not part of the public SDK, deploying applications to the ROM is not typical for 3rd-party developers.
Ask your BDM and/or the person who migrates your application to a ROM image.

My exe is in the ROM image so it is installed to Z drive. I have created a private\sid path in C drive and storing my <appname>.ini file in it. When I do master Reset Im losing this file. Is there anyway i can retain it?

I think that you will find thats why its called a master reset, rather than just a reset. What you are protecting against is a corrupt data file turning the phone into a brick.

IIRC the device wipe just marks the c drive as corrupt and forces a reformat of it.

It is not that obvious to me what you mean on 'master reset', but the 7780-reset is the only one which is supposed to be survived by some data.

Im just exucuting Master reset, which is present on the device
Control Panel UI.

Is this S60 or UIQ?
On S60 hard reset is *#7370# (ie RES0)

That one is not really supposed to be survived. But you can experiment with the related API - if you are entitled to experiment with it.

Thanks in advance

wizard means there are non in public SDK. and you may try with non-public apis if you have access to them.

I have no permission to name the API, that is why I have suggested to ask your internal contact in Nokia (BDM or somebody else - in fact I do not know the hierarchy).
