Thanks again.

* somehow I could not get into the diagnosis mode (I am sure I did see that inventory screen before though ...) I held the battery icon for as long as 3 minutes to no avail...

And when I tried to upload gmapoem.img, it won;t let me, claiming invalid file :-(

Let me repeat what I understand is the procedure to flash the image. Please correct me if I am wrong --

1. load the original firmware gupdate.gcd into rgn_tool
2. unselect fw_all.bin, keep boot.bin selected
3. load logo.bin, select
4. save to boot_logo.rgn
5. use updater.exe to install boot_logo.rgn

this should replace logo (if it is at the right place) but not alter the actual firmware. Correct?

thanks!
