Faraz; I've experienced the same problem as well. As a matter of fact I just sent my *second* N810 back to Nokia for repair. The first one worked for about 4 weeks and then showed the same behavior that you experienced. So I sent it off to Huntsville, AL for repair and Nokia sent me a brand new one in exchange saying mine was unrepairable. This new one lasted about 6 weeks before bricking. I just returned it last Friday. Hopefully the third time will be the charm. The only thing that I've noticed is that times between charges get shorter and shorter meaning I have to recharge it more frequently. I'm not doing anything unusual with my IT and like my 700 (which is stable as a rock by the way) I've been leaving the N810 on all the time.

I didn't realize you could reflash the N810 if it couldn't boot. It never occured to me to try that.
