Re: Boot Issue N900

Yep, a few minutes would be normal. (also no idea 'how' long, last flash around 2013?)

Nothing wrong in the log.
So pichlo's advice, once again, is worth a try (pull battery, wait, push in again; that cured a few weird quirks for me already).
But I am afraid this time it may not help and it could be some HW fault. Possibly open it, clean from dust and check connections/cables?

As peterleinchen says, the first boot takes a few minutes. I don't remember how long exactly, could be 10 minutes or more. But the OP said overnight. That is not normal.

Re: Boot Issue N900

I have no idea about CSSU-devel.

i left the phone all night without battery, then started this morning, boots, appear nokia logo, five dots animation, nokia handshake, locale settings, five dots animation again, and finally the desktop, then reboots forever

Flasing that files for a global version, will fix it?

Thanks

I will give that a try and report back.

Is there any way to flash backups now.. I cant find the recovery screen? I have a few backups from long ago when I used this device for a daily driver now I just use it for fun.. as you all know this is one of the best devices for hacking / packet injection with little to no configuration needed for it to work.

Before I starting all this flashing I did try to restore a backup and It failed I forget the errors so then I just decided to start fresh and flash with new images (combined/eMMC)
How is recovery accessed or reflashed?

I dont think this is an issue but I did a battery bypass by soldering +/- wires to the phone where the battery connects so its get power by a usb cable. Assuming the eMMC doesn't need power to keep storage.

Sorry, you did what? I am not 100% sure I understand. Do you mean you soldered the USB power directly to the battery terminals? That would be a sure way of frying your phone (the battery voltage is about 4.2V max; USB gives 5V). I hope this is not what you meant.

The N900 needs the battery to boot. It can be replaced with a dummy circuitry but it is not as simple as just the +/- wires, even with the correct voltage. The middle terminal is also important. The phone uses it to check the battery capacity.

The eMMC is non-volatile and does not need a power backup any more than any other flash storage.

Connect thru a 110k resistor to GND ;)
