*HELP* SX-66 main battery invisible to device

[qgyu]

When I tried to turn the device on, it only displays the version information before rebooting itself again and again ... and again. I finally put it in the cradle and it booted all the way up to the setup screen and was running properly (sans all the data and the applications I've installed, of course). The backup battery was down to 20% at the time.

Now, the battery screen shows Main battery at 0%, AC Only, and the backup battery at 100%. It doesn't show any charging activity to the main battery.

The battery on it right now was fully charged through the aux battery charger, and the backup battery is also fully charged. I've tried another fully charged battery with no luck.

I slapped in a freshly charged battery last night before going to bed. Everything was working just fine then. The phone was sitting inside a leather case all night and never moved.

PH20B1 B 1 WWE E XGULB001 1.33.10 1 0 1.33.110 1.06.02 06.02

I'm running the original Cingular ROM unlocked for use with a T-Mobile SIM.

Thanks for any help.

I updated the ROM to 1.40.00 and Radio to 1.13.00. But since EXT ROM update takes too many reboots and after each reboot, the directory would be hidden again, so it's still at 1.33.110 for Cingular.

Any thoughts? Please help. I'm aboslutely losing my mind. Do I have to call Siemens for warantee?

Not even speculations?

I have somewhat a similar problem, I have an XDA IIs, and I bought a 2400 mAh battery, and when I place it into the phone and plug in the USB Charger the light doesn't come on, so I turn on the phone and I goto power and it shows AC Only, and backup battery is full. I can't find a way to charge the battery since I bought it I need help =/.
