N810 map program fails on start

Question

I flashed my N810 to the latest OS version today. I started the map program, but I got a "no memory card found" error, although File Manager showed both my internal memory card, and my 2Gb external, empty, SD card. This is better than in the past, when it used to crash with no explanation.
I googled for answers and I found suggestions to remove the "map" folder on the internal card, but when I tried to do that, the system told me it is a read-only folder.
I tried the "Contact us" link on the Nokia support website ( http://www.nokiausa.com/A4410063 ), selected the subject of inquiry as "Maps", got pointed to https://www.nokiausa.com/A4686840 , clicked on "Support, and got into a dead-end page of pre-canned answers that did not address my problem. So much for "Contact".
The GPS and maps were a big part of the reason why I bought the N810 (my first Nokia product), but they never worked. This is really disappointing. Now I am going on vacation and I was really hoping I could use the GPS and maps. Can anyone please help me?
Thank you,
I. Vlad

Answer 1

Thank you! It worked. To summarize the long thread in the link above, here is what I did:
1. Enabled Extras
2. Installed rootsh, from: Application Manager... Browse Installable applications... All
3. Open terminal, then typed:
root
lsof /media/mmc2
Nothing was listed as using the internal card. From that point on I followed these instructions . I did:
umount /media/mmc2
sfdisk /dev/mmcblk0
Then I was asked for cylinder sizes for each partition (4 partitions). So for the first one, I typed in 0,,b all on the same line (ex. /dev/mmcblk0p1:0,,b ), then for the next 3 I just hit enter and put nothing in.
I rebooted the device, went to file manager, clicked and held on "Internal Memory" and then I clicked format.
Thanks again!
