Rescue Os?

Re: How to extract/backup full ROM?
 

Ok, guys, better to clarify something. I explained to Meamish as well, I didn't want to raise hopes or anything without having something solid first, but it is better to clarify it before we continue with more discussion about N900.

I never mentioned it is about N900. It is about a very rare, unreleased prototype, for which we only had a leak of renders from evleaks, not even a real photo of it, if it was real or just a concept. I also asked at its old thread. It is this one.

It is most likely Linux and from all Nokia OSes, the closest one seems to be Meamo, that's why I try to find tools through Meamo to somehow extract its firmware and share it with the community here. But so far, it seems that I will need something more generic for Linux, not specific for Meamo. Its OS could be a variant or an evolution of Meamo, or something completely different. Also, it seems to be either early/buggy or even unfinished like the Kataya one.

In weekend I will try to take some photos and create a new thread, but in the meantime if anyone has any further suggestions about cloning entire memory or something similar, with minimal risks, I would be very happy to try it out :)

I suggest to first check the USB ENUM messages, ideally on linux
Look into linux' syslog (tail -f /var/log/messages) and watch the output while you connect the device to the PC via USB

I wonder if Pali knows some details about an option to read out firmware using 0xFFFF. Gonna ask him on IRC if I find him

Since you mentioned tools to access BB5 over in that other thread: N900 OS never runs on BB5 baseband, it has its own OMAP processor much similar to a Beagleboard-xM

This means I need a Linux pc then, right? I think I still have a live-USB of an old distro, maybe it does the job

Re: How to extract/backup full ROM?
 

what also might make sense (while you already got a linux running):
make the device connect to your WLAN, then find the IP it got (look at your router for example to find out) and run nmap against that IP ports 0-65535, with service-detection/analysis for open ports

Unfortunately, I haven't managed to get to the settings of this prototype to connect to wifi... I also wanted to try its internet as it has several bookmarks including references to Meamo and Meamo browser...
