Polaris won't boot

[nbr_uk]

Not sure if this is a battery related issue as I removed the cover and battery to put another SIM in to find out it's no. Since putting the battery and cover back on I get the splash screen for the ROM I'm running (Diamond), then the HTC annimation then it reboots. It will also only get that far when the power is connected - otherwise it won't even start to switch on.

Any ideas? Also is there a way to reflash as I don't want to send it back to the provider with a non-standard ROM.

Any help much appreciated.

A bit more information - if I leave the charger plugged in it just loops round and round with the splash screen and the HTC animation.

I had this on my first polaris it did it on the 1st day so i returned it and got a new one... Couldn't hard reset either...

Try going to the bootloader manually and flashing a new rom following the instructions that are repeated over and over in these forums :D

Thanks for responses - it's working fine again now. I think one of the battery contacts may be faulty as it wouldn't run without the charger until I pressed them in and then re-inserted the battery.

Hello, my polaris has stopped responding when I touch the screen, it is locked and the only thing that is working is reset, and after reset the screen is locked. It do`nt respond on hard reset or wìll not go into boot loader. On service they say there is now garanti(I understand) because I use a rom from XDA. Is there any way to get it into boothloader or hardreset, exept from the usual ways? or do I simply have to throw the hole thing?
I can reciew phone calls.
