Hi,
I tried upgrading to 52_2 from ubuntu feisty using flasher-3.0.
I followed the procedure in maemo.org but did not know which the Home button for N810 is. I tried the ones mentioned in this thread but without success. Here is what I got:

vj@vj-laptop:~/n810$ sudo ./flasher-3.0 RX-44_2008SE_2.2007.50-2_PR_COMBINED_MR0_ARM.bin -f -R
flasher v0.8.7 (Oct 17 2006)

Suitable USB device not found, waiting
USB device found found at bus 001, device address 022
Found device RX-44, hardware revision 0801
NOLO version 1.1.6
Version of 'sw-release': <no version>
vj@vj-laptop:~/n810$


I think "About Product" started to show <unknown> for Version after my first unsuccessful attempt.

What am I doing wrong?

Thanks.
