[HD2 General] br0adband:
Ok, I'll try to make this short and sweet and we'll see what happens. I spent the last 2 hours scouring this forum (pretty much the Bible for the HD2) and some other places and I'm still kinda dead in the water.

Here's the situation:

I just grabbed a used HD2 in excellent cosmetic shape. It was from a pawn shop, for $100 cash, and the device would power up at the pawn shop into Windows Mobile 6.5 just long enough to see Sense starting to load, then the battery would complain (probably hadn't had a proper charge in a long time I'm suspecting), then it would go into the "Goodbye!" routine.

Fair enough. So I get it home, and they included the HD2 USB adapter/charger, and I have my own 100% working microUSB cable. I verified the charger works by attaching it to my microUSB cable and then plugging it into my current phone (a cheapy LG 900g on NET10) and it works fine, no issues for power or data connectivity.

So I unplug the cable from the LG, plug it into the HD2, and attach it to my Belkin USB hub (powered, with nothing else attached to it, no other USB devices) and after a few seconds I get the orange charging light on the HD2. Note, it's still off, I didn't turn it back on after it shut itself off. So I let it charge for a few minutes, then I realize I should probably be better off using the actual dedicated HD2 charger, so I unplug the USB end from the USB hub, the orange light obviously goes out since it's now without that source of juice, then plug it into the HTC USB charger and...

Nothing. Absolutely nothing. No orange charging light, no response when trying to power the HD2 up, absolutely nada. So now I'm frustrated. I disconnect the USB cable from the HD2, take off the back cover, remove the battery, wait about 1 minute, reinsert the battery (leaving the back cover off), attempt to power it up, no luck.

Plug the charger back in, and I can feel]/i] the tiny vibration motor just kinda "tick" ever few seconds; there's something going on in there, I'm certain. Repeat the unplug/remove battery/wait a minute/put it back together/plug it back in a few times, and then I get something:

The HD2 will vibrate and the screen will light up with the "Stick Together" graphic, for about 1/2 second. Then it's off again. Then it's on again, and off, and on, and off. It's a loop of some kind, but it's random. Sometimes the on/off happens every few seconds, sometimes it's 10, 15, 30, sometimes a full minute goes by before it'll "flash" then nothing again.

Now, the whole time this occurs, the orange charging light never ever comes back on again - it has not come on again regardless of whether I'm plugged into the USB hub or the HTC charger, it just doesn't light up anymore, so my current suspicion is that the battery itself is simply so "dead" it won't accept a charge of any kind - at least that's my current hope, as odd as that sounds. I can get a new battery, of course, it'll just take a few days to get one (ain't paying full price here in Vegas, will order something online).

I'm stumped. I check the contacts, they're fine, they were very very slightly bent but they're ok now. I don't know what else to do since it does seem like the battery could be the culprit. It'll sit here and just flash every so often - it's been plugged into the HTC charger for the past 30 minutes straight but, I'm not even seeing the flashes anymore (the past few minutes I've been typing this post).

Maybe the battery is to blame, I don't know, but I'm hoping that someone can say "Yes, that sounds like a completely toasted battery to me, get a new one" or whatever.

Any opinions? Anyone seen this particular behavior before? I do a search for "reboot loop" and what I find are people with HD2's that get stuck at the "Stick Together" screen and, well, that's not what's happening here - it shows that, for a 1/2 to 1 second on occasion, then nothing. The vibration motor kicks in when the flashes occur, as well.

It's like it wants to fire up but just doesn't have the power to do it - and since the charging circuit isn't kicking in (no orange light), well... that's my guess.

That's about it. If anyone has any advice, I'm reading.

Thanks, and have fun, always...
