Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done

Thank you for link, I will try after this my run work will have no success. Thanks!

If I run dmesg, it should save somewhere some log, don't it? Because I see only the last few lines, which can be displayed - no scrolling. But what I saw even without scrolling is massage:
Unfortunately I cannot find this exactly means or how to repair this (if possible).

EDIT:
What lo9314 suggests doesn't function on my side. When try to use flasher, it cannot get n900 in update mode as suitable device and is still waiting.

Now I really don't know, what to do. Should I set N900 into storage mode and repatition eMMC? I definitely don't know, what part is bad, why cannot boot Maemo...Maybe that's the right time to offer half of kingdom for a solution!

If you can type in special characters you can redirect the output of dmesg to a file using this command:

The log.txt will be created in the directory you are in at the moment you execute the command. You'll somehow need to access the file of course afterwards and I'm not sure if this is possible. If there's no option to scroll like you said you can also try:

Thanks, this works good -> I have log. Nano function good on this file, so I check it. Because I didn't find a way how to transfer it from N900 before battery drained, I re-write lines, where was not "Done", "Ok" or memory adress as postive result as this:

(without "positive" lines)

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

I have one new observation.

When I try to update Vanilla in Update mode, it find and refuese the device connection. - the USB symbol is shown, I press the Enter on keyboard with command on Terminal and symbol of USB on N900 display is gone.

So, cold flash it cannot do, because it cannot see the device. But Vanilla cannot do, because it refuse it. After 2 minutes the device (if is in R&D mode) change on the screen - some information about kernel, product, hw-build are added (green font) and flashing with Vanilla STARTS! And ends with success.

But, the problem is stil the same - cannot boot the device, only NOKIA is shown.

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

Sorry, it's probably a dumb question, but you did press "u" while plugging in your N900, right? Otherwise I would try a different usb cable and a debian live cd. Since you can't even install the temporary nolo bootloader (which should always work) I'd try looking for the error elsewhere.

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

Yes, I always press "u" and check if it is in Update Mode. No question is dumb in these thread.

Ok, I will try the different cable. Debians I use are different, but the same situatuin everywhere (when need to Cold Flash, still "no suitable device").

In fact, I see the problem in something "third". The Vanilla and Fiasco can be done quite without problems. But reflashing these two doesn't help and the problem is like before - boot looping with no result, restart, boot, nothing, restart, boot, nothing....Moreover the Cold Flash telling "no suitable device" - on Windows, and also on Ubuntu. What's the difference, between Vanilla/Fiasco flash and Cold Flash using Fiasco bin file?

What next is important to boot OS, instead eMMC, kernel?

What could cause loop booting with no result to infinity?

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

Maybe try this:
flasher-3.5 --enable-rd-mode --set-rd-flags=no-lifeguard-reset --set-rd-flags=no-omap-wd --set-rd-flags=no-ext-wd
and flash latest image once again or/and flash fb kernel and watch logs:
flasher-3.5 -f -b -k zImage-2.6.28-omap1-fb

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

Ok. I tried this on Windows. I'm downloading image of Ubuntu, until now - if use linux - run from Virtual Box. Here's the result, no fault:

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

please don't disable R&D mode. Now you have fb kernel. I know it's hard but did you see any errors on n900.

Re: N900 - Cannot Boot, but Flash VANILLA and FIASCO done
 

So, the kernel don't start. After these three commands, N900 is still in R&D mode, and the NOKIA (with symbol of rd mode) is lighting.

EDIT:
fb kernel starts. The error messages I saw was something like before in RescueOS - Also I see the: tpa6130az - read (and than also write) failed
