- Hard resetting the mobile.
-Restarting my XP PC and switching off Anti virus and Fire wall .
- setting up Samsung modem ( more than once) .
- connecting to active sync , and then switching off the mobile.
- running the updater and then resetting my device.
- Pushing the start button which is active now.
I did that twice for PV02 and PV03 m and in everytime I get "Checksum failed "
I thought I had some experince since this is my 5th rom upgrade without any problem.
Can some one help please ??
