How to rescue MyDocs from Nokia N9 16GB?
My question is already stated in the title -- following some more info how it came about (italics), and at the bottom a summary what I tried so far:
Probably, I was incredible stupid today. After increasing numbers of issues with the tracker, which couldn't be cured by the usual means, I made a tracker reset. No big deal as I saved everything to the MyDocs partition. To save the SMS I used QTweakN9 (http://talk.maemo.org/showthread.php?t=80600), which I installed the first time. During the first start the "bash" gets installed, too. That reminded me to search if there's a package of my favorite shell "zsh" for the N9. Yes, there is (http://talk.maemo.org/showthread.php?t=55947) and I was happy as it worked really well. So happy, that I appended "exec /bin/zsh" to my ~/.profile -- changing the login shell is sometimes not such a good idea, so I used that workaround. (That was mistake no. 1 I suppose, but I'm not sure, that my problem has something to do with that or if that was just an accidental coincidence...) However, everything worked well and after an hour everything was restored from tracker reset. Haven't done a backup to my PC quite long, so I thought that now would be a good time. I already had MyDocs opened in the explorer, but then I realised I didn't made a fresh backup with the internal N9 backup app. So, unplugged USB (mistake no. 2), and was about to start the backup, but the keyboard didn't appear to name the backup... crap, what's going on?! I already wanted to copy&paste some string, but than made a reboot instead (mistake no. 3) -- "it won't hurt". But it hurt badly! The N9 get stuck at the NOKIA logo -- nothing happened anymore. (So at that moment no boot-loop.) Damn! I searched the internet and found some options I have:
I have no more ideas, but I deeply hope some of the pros in this forum have another one. Especially I'm interested, if somebody can confirm that the approach with the rescue initrd is working also with 16GB devices. My phone is not SIM locked, but however I have MfE accounts setup (which can trigger the device lock, according to a page I did not find anymore). Thanks a lot in advance! |

try again the moslo kernel but on linux because it will only work in linux . I used it to recover files from my damaged-screen N9 .

Thanks for your answer! I'll give the MOSLO kernel another try. Today I was not sure, what to expect. Should the device boot into some kind of command line or is this "Warning you modified your device" screen the final state?
The README says you should do "sudo ifconfig usb0 192.168.2.14" -- do you remember, if one needs a special kernel module? The default debian kernel does not offer a network device usb0... |
Re: How to rescue MyDocs from Nokia N9 16GB?
IIRC g_multi (the kernel module which exposes a USB Composite Device with a USB Ethernet and USB Mass Storage device) is supported by the host-side Linux drivers for RNDIS or CDC ACM.

If the correct module is as Hurrian says the rndis or cdc-acm module, both are available on latest stable: Code:

I tried the MOSLO kernel again, with Debian 7 (Wheezy), Knoppix 7 (also Debian based) and another LIVE-Rescue-System (probably Gentoo kernel).
The modules you both mentioned are present and load w/o error. However after the flashing of the MOSLO kernel, dmesg tells me: Code:
[ 202.780040] usb 2-2: new high-speed USB device number 4 using ehci_hcd Also the USB Mass Storage Mode only works as far as that of the Fix-MALF kernel (initial post), no possibility to read the reported SCSI device /dev/sdb. After searching some more about that latter problem, I stumbled over a forum post (http://debianforum.de/forum/viewtopic.php?f=13&t=131373, german) describing a very similar behavior with a simple USB stick -- the bottom line was: Flash Memory damaged, Data lost, Stick dumped to landfill :( I think I have to look for a replacement, too. Perhaps I can get a (screen) broken unit on ebay... Thanks again for your hints! |
Re: How to rescue MyDocs from Nokia N9 16GB?
Yes, it looks that your USB interface or the flash memory might be broken, if neither Fix-MALF or MOSLO method export anything to your computer. Too bad.
Apart from the USB bus, there is nothing much you can do. There is serial maintanance connection pins under the SIM tray, but you need a special adapter to access that interface. |
Re: How to rescue MyDocs from Nokia N9 16GB?
multiple options:
- telnet into moslo kernel rescue mode and check partitions from there - rescue kernel, most likely you should not see anything in proc/partitions, did you even try to mount the whole device and/or check with fdisk how it looked? vs trickier version - connect serial ttl converter to rx & tx pins and login to serial console and do magic in there. |

1st post said that it exported sdh, thats why I was asking that did he do fdisk on /dev/sdh.
And most likely its just debian usbnetworking which sucks, maybe he should try ubuntu or something. |
