Hi,
I had a similar problem while using my N900 with the in-car charger. I was using the N900 as a GPS and it failed half way through the journey with that well known dry-swallow noise and getting very hot indeed.
Luckly I could switch it on later on without loop-reboot but I've got another issue.
My keyboard started to mis-behave. The "upper-case" key, the letter "t", and left and right arrow keys no longer work. The letter "e" key while pressed produces "et". Is that "E.T." trying to phone home?
It feels like a joke but it is not funny at all!
I've tried to change this behaviour by trying different foreighn keyboards but still no joy. Changed the language, no joy. Flashed OS (thanks God the U key still behaves as U) but no joy.
The phone also "dies" at least once a day for no apparent reason, i.e., it swallows hard and deep and faints, going into deep sleep!
Any other suggestions appreciated. This is the first phone that dies on me so often and that I feel I cannot rely on in times of need.
I haven no guarantee as I've bought it in working order on ebay.
Thank you kindly.

I have exactly the same problem with my N900, I didn't use a car charger though. I've tried reflashing it and doesn't work.
I can get it out of the reloop only if i turn it on when connected to the wall charger.
Has anyone tried changing the battery?

I remember that the reboot loop is a kernel problem. search on this forum for the official kernel and flash it with flasher3.5 maybe it will help without the need to flash the whole os.
It works for me
It works for me

First of all an apology if this is covered somewhere. I am currently on an overseas trip and while I have done some searching for possible solutions I haven't exhaustively done so.
My N900 started continuously rebooting (while it was charging off a car-charger during a road-trip. No explicit action such as installing or updating a program kicked this off). It starts the normal boot sequence (the 5-dot animation) but after a short while the sequence always stops on the second dot from the left (unsure if this is of significance) and the phone reboots.
I have re-flashed the OS using flasher-3.5 several times. Regardless, the phone's behaviour has not changed. I have not yet flashed the eMMC as I don't want to lose the data on that, if at all possible, hence this posting.
Is there a way to boot the kernel into a minimal rescue mode which would let me access the eMMC from a PC to backup the content?
Alternatively is there a rescue kernel or custom firmware I can flash onto it to the same effect?
So far I have not found any info on kernel boot parameters for the N900 or special rescue/recovery modes it can be booted into. I have also not found a detailed explanation of the command-line switches to the flasher tool (eg, what is 'cold flashing'?)
Any help much appreciated!

(V.glad now that he took another phone with him on this trip...)
No in terminal (assumign linux or max) type:
flasher-3.5 --enable-rd-mode
for pc
flasher-3.5.exe --enable-rd-mode
This will enable rd mode on your phone. Unplug usb cable. Your phone will reboot, and shoud load all the way up. After it does, turn it off. Hold down the u key again, and plug in the uSB cable again. Now type in your terminal again:
flasher-3.5 --disable-rd-mode
for pc:
flasher-3.5.exe --disable-rd-mode
That will return your phone to normal operating mode.
As a curiosity have you already updated to PR1.2?

Edit: If this was a kernel problem, you would not see the blinking dot process. It would go to the Nokia Screen, go blank, and then reboot continually. This is a seperate issue from that.

the phone boots normally at first but when the desktop starts loading, it restarted again and again.

no initfs \o/
rd mode didnt work, loop still happen.

I too have a crocked n900,
Works ok with a charged battery apart from it does not respond when a usb cable or wall charger are plugged in so cant charge or backup data (apart from bluetooth).
If i turn the phone off and plug any microusb lead into it it goes through the nokia screen with back light off and dots loading loop process.
Once i turn it back on it boots fine but cant charge or use as mass storage.
Any ideas?

@htchang - The final update to my story was that it took 2 returns to Nokia to get a working N900. They never told me what was wrong with the original unit. Have you tried reflashing your phone? It sounds like yours isn't as badly broken as mine was. You might still have to resort to a warranty repair though.
