Hi,
How can I backup my current ROM ( which comes from my operator) the easiest way? before upgrading to WM6.
To keep my warranty works ( in case my device needs any repair in future, I can downgrade it to the original ROM )

I have JASJAM device.

Try to search in WIKI if the ROM you have installed is uploaded ;)

IPL & SPL: Use NBHextract to extract them from any shipped NBH.
MainSplash & SubSplash: Use NBHextract to extract them from any shipped NBH, if no NBH is available containing your splash screens, simply never flash them to keep them intact.
Radio:Use NBHextract to extract it from any shipped NBH.
ExtROM: Unhide it and copy the contents over activesync or to storage card.
OS: dump it (http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoDumpRom) and reconstruct it (http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoReconstruct).

When you have all the *.nb files, create a NBH file with nbhgen. To put back the extROM simply unlock & unhide it and copy the contents again.

Be sure to flash HardSPL on your phone so you'll always be able to flash the backup rom you've "created" and if you ever need to flash it be sure to use SSPL (so you can overwrite the bootloader).
