Flashing the Nokia 770

I wanted to update my Nokia 770 with the latest root image, so I flashed the device as described at maemo.org.
Everything went well, but it did kill all the changes I had made to the system. The 770 was for all practical purposes reset to factory default. Only the memory card was unchanged.
Note to self: do try the backup/restore utility the next time!

I really do feel silly but could you give me a more detailed approach on how to install this stuff. As root in the terminal I get a “-sh: ./flasher: No such file or directory” message. What am I doing wrong here ? The 770 is connected and off to my Mac through the usb cable. I don’t get it. Also what do I do with the .bin file. Thanks for your explanation. Manuel

I can’t open the flasher via the terminal. If I double click the flasher it opens a terminal window but when I enter command
“./flasher.macosx -F Nokia_770_0.2005.45-8.bin -f -R”
I get the “No such file or directory” message and that’s about it

You have to

– open a terminal window
– move to the directory where you have the files flasher.macosx and Nokia_770_0.2005.45-8.bin
– make sure flasher.macosx is executable (chmod +x flasher.macosx)
– then flash the device

It is not something you can do through the GUI. The flasher is probably made for developers not endusers.

With the new image release from Nokia I decided someone had to do this, so why not me.

This image is a full image, like the original “Nokia_770_SE2005_3_2005_51-13.bin” from Nokia.
What I have done is change the gainroot script so it ignores the R&D flag completely and just does as it’s told.

Due to my reconstructed rootfs not being identical in size to the original image this image will actually flash a tad faster (being smaller). I have tested this image on my own device only, and it does flash with both the Linux flasher and the Nokia 770 Software Update Wizard.

If anyone can explain to me why my image is smaller, I’d apprechiate it. As for now I am just happy it works. I did make sure the new image file has the correct format. That is, it contains the correct information about the lengths of each image-block. The fact that it became smaller puzzles me a bit, but who cares.

Enjoy, and I hope you find this usefull.
