N900, virtually brand new, running PR1.2 (as supplied).

I noticed yesterday that phone had dropped off the network and had a Red Line through the SIM Card icon on the home screen. I rebooted it, and it came back. Didn't think anything more of it.

Today, the phone took a long time to boot, and a banner appeared during the boot up (blinking white dots) saying:

"All telephony functions, including emergency calls, are disabled due to a communication error. To recover, you might have to reboot the device".

Tapping the screen clears this, and boot continues. The same warning is repeated when reaching the desktop. The red line is through the SIM card, and sure enough, it's disappeared. I tried sending various dbus-commands to com.nokia.phone.sim, and dbus is claiming there is no .service present to handle the call. So it looks like either hardware failure, or driver failure.

I've reseated / cleaned the SIM (which is a newish SIM) and swapped SIMs in and out between different devices, so I'm confident it's not the SIM.

Ovi Suite 2.2.0.245 is claiming it can't recognise the device, when it was able to recognise it just fine yesterday.

I tried to flash the device, but the flasher is dying like this:

Code:

Bootloader error log follows:

  ERROR: Error processing request, stalling
  ERROR: EP0 STALL sent
  ERROR: Premature end of control transfer
I've downloaded the latest image, both the UK variant (203) and the Global (MR0). It looks like my device has the Vodafone variant (205) on it, but I can't find a source for PR1.2 205, and anyway, should that matter?

Having tried this a number of ways, I concluded I had a real problem on my hands, and it was time to package it up for a warranty repair. Before doing that, I started to clear down personal data, and uninstall apps I had added in.

I tried to uninstall *# Starhash Enabler. It wouldn't properly uninstall, claiming there is a file missing. I had to reinstall it (from the command line) and then uninstall it again.

I also noticed that some of the thumbnails in my Photo library were broken, which makes me wonder if the drive has got corrupted or damaged somehow?

So, some advice needed:
  • It is flashable? Nobody else has reported that same flashing error. Can I flash the eMMC and then the image, and would that work better or risk bricking it?
  • Can I low-level format the entire device, marking off any faulty chunks (sorry - more used to dealing with physical disk drivers here)
  • Any thoughts on the underlying cause? Faulty SIM card reader? Faulty memory? Corrupted install?
  • Is it worth warranty returning it to Nokia? (It's in warranty)

Thanks,
