Hello,

Unfortunetely my N950 doesn't boot up. I tried reflashing with every available firmware.

The current firmware is: "DFL_61_HARMATTAN_40.2012.21-3_PR_RM680".

I'm also able to reflash the kernel and mount rootfs. No existing /var/malf (therefore not the MALF-problem)
But nothing helps!

Current state:
After plugging in the battery the device starts up showing the NOKIA-Logo but then the screen turns black and after while the display turns out (but the device is still running).

Maybe there is an expert who can help me with this.
Please.

Have you tried to disable the watchdog with the flasher?
Don't know if all flags from N900 flasher are the same for N9/N950.

This could prevent a boot loop:
Code:
--set-rd-flag=no-lifegard-reset
These could be also interesting:

no-omap-wd
no-ext-wd

That statement worried me as just flashing once with "DFL_61_HARMATTAN_40.2012.21-3_PR_RM680" was quite enough as that firmware was hard enough to source.

With regards to trying R&D mode, enable with:
HTML Code:
--enable-rd-mode --set-rd-flags=no-lifeguard-reset
and disable with:
HTML Code:
--disable-rd-mode
In what state of charge is BL-4D battery as at least can be charged outside device if necessary rather than using flasher?

State of battery?
flasher -i
should show you / and probably charge also, but maybe you need to give full flash command (kernel is enough) to charge, there is a dedicated thread here on tmo.

Do you have also the eMMC image? Then at least worth atry is full flash eMMC and firmware wiping all.

Unfortunetely, the flags didn't solve the problem. I concatenated them, too, like:
Code:
flasher -F img.bin --set-rd-flag=no-lifeguard-reset,no-omap-wd,no-ext-wd

The first command changed nothing but the second one let's it vibrate again and the notification-LED is fading instead of switching from on to off. But then the phone powers off. That's a little success I think.

Yes, I'm using the eMMC image from "Win_OCF_02-6_RM680-RM680-OEM1.exe".

Code:
flasher -i
doesn't show the charge but by flashing with:
Code:
flasher -F img.bin --enable-rd-mode --set-rd-flags=no-lifeguard-reset
Code:
flasher -f -F img.bin --erase-user-data=secure
Code:
flasher -f -F img.bin -F emmc.bin --flash-only-mmc
Code:
flasher -F img.bin --disable-rd-mode
Code:
flasher -F img.bin --reboot
it shows "Battery level 96%, continuing."

The battery seems to be okay and kernel reflashing didn't help.
The screen keeps being turned out.

Have you tried to boot the rescue image with the flasher?
Does it stay on or does it reboot or switch off too?
Maybe with the rescue image you could look in some log files or check the data structure. Or install manually a package which gives you more log file output.

Thank you for your answer.

Firstly, I tried using Windows 7, but then I switched to the rescue image.
It doesn't reboot. When turning on the phone by power switch the nokia logo pops up in white screen, then the display turns black and after a while completely out.

Do you know which files could be useful? I'm able to look into the rootfs, that's no problem at all.


PS:
Maybe it could be useful to know which device I'm using.
It's "RM-680, hardware revision 0322" and it's a black 64GB device.

I found this thread where someone seems to have a similar problem:
https://talk.maemo.org/showthread.php?t=90868

But It's not very helpful.

unfortunately i never owned a n950, as it was the device i ever wanted. try df -h, lsusb or dmesg and check the partitions, clear the tmp-dirs and lock-files. put watchdogs on default, cold-flash the newest image. just suggestions...

df -h, lsusb, or dmesg can't be used.
After flashing ubiboot using:
Code:
flasher -k zImage_2.6.32.54-ubiboot-02_301013 -l -b
I'm able to mount the N950-partitions and network device (usb) turns up but
Code:
telnet IP
says: "telnet: Unable to connect to remote host: Connection refused"

The tmp- and lock-dirs are already empty.

Watchdogs set to default by using:
Code:
flasher -F img.bin --clear-rd--flags:no-lifeguard-reset,no-omap-wd,no-ext-wd
Cold flash by using:
Code:
flasher -c -F img.bin -F emmc.bin
fails because of this error:
"ERROR: You have to supply 2nd image for RM-680:0322
ERROR: Cold flashing failed"

PS:
I've tried the newest ubiboot ("zImage_2.6.32.54-ubiboot-02_23032018"), too but it doesn't make any difference.
Maybe the N950 can't be accessed via serial console over USB?

/var/log/syslog

could be useful. It is a logfile from the standard installed simple-syslog-daemon.

Better would be to install klogd and sysklogd from developer mode. Maybe klogd is enough and would be easier(no need to remove simple-syslog-daemon).
But as you can't install on the mounted partition, they need to be extracted and I don't know if something like this is possible because of this aegis thing. Which also stopped me to work more with harmattan.

Edit: Maybe open-mode kernel could be of help.
