Update at post #26 (handset returned from HTC alive and well)
Urgent help required please guys - help me rescue my very poorly HD2!
Phone is completely dead at the moment. Battery is completely dead and attempts to charge it are not working - however I'm sure it's not the battery that's the problem!
I've been flashing different radio roms this last couple of days going from 2.08.50.05 to .08 and back yesterday to .05 because while on .08, the back of phone was getting really hot and the battery was draining very quicky. Late yesterday afternoon it discharged completely while I had it on-charge!
Since then it's remained dead! Initial attempts to re-charge saw the orange LED come on for a minute or two, at which time I tried a hard-reset but it froze at the point of making the selection to hard-reset after the brief bootloader screen. On one more occasion the LED came on for say 10 seconds before disappearing again and since then - nothing!
Taking the battery out for all of last night and at least 20 times today has made no difference. Trying to charge it via (original) charger and via usb cable has not worked. No LED, no charge (though interestingly it still gets warm at the back when on charge), can't boot, no response, nothing, nada.
Helpful guy in O2 shop spent 40 mins helping me out earlier today (he's a XDA forum user who flashes custom roms from here too on his HD2). He took his charged battery and put it in mine with pretty much same result! White HTC bootscreen came on for a few secs before dying again. Couldn't start/boot up my phone using his good battery, yet after putting my battery in his phone he was able to begin to charge it, proving I think that, it's not battery that's to blame for this, but an internal fault with the power-unit of the hardware, (and/or perhaps with the charging port).
I'm convinced that the power-unit is the major issue, and that as it seems to be over-heating quicky, then it shuts down immediately from doing anything. I could be wrong of course.
Sorry for the lengthy story guys, but now feeling really low that I can't seem to sort this. If I cant start it up or get to the bootloader screen then I'm not going to be able to flash a stock rom to get this problem fixed under warranty, so as you can see, I'm really frustrated!
Any help, advice, suggestions etc would be gratefully received and much appreciated too! Thanks in anticipation.
Edit: sorry should have said that I've extensively read these forums today and found many similar (but not exact same) threads/posts, hence the new thread.
