The solution is easy. First charge the battery conecting the device in Boothloader mode (press and hold camera buton and press power). Conect the usb cable in bootloader mode and instal the ROM you want.
good luck

Can some one explain the steps to get in to bootloader mode or usb mode. I have the same problem with my MDA. I need to get a usb mode to update the ROM. the battery says unknown and as it turns on its messing the GSM rom so no calls can be made out. The charging icon is always on, and I'd hate to have a $500 paper weight on my desk
thanks,
Adam

To go to bootloader hold camera button down (don't release it) then press the reset button with stylus (don't release camera button) then release reset button . When you have a tricolor screen then you can release the camera button. You're in bootloader mode.

charmer dead...

flashed charmer with wizard...an now its totally dead...cant enter boot....anyone can help...
dead - can you describe it better? is it freezing in the splashscreen? or not powering on completely? have you tried to charge it using normal charger, not usb sync cable?
what about bootloader, dead too? try to hold camera button and press reset. if three color bars appears, you have a reason to stay calm.

complitely dead...not powering...cant enter boot...
hmm, it looks bad. I don't have any valuable ideas...but:
maybe you may try to charge battery in another charmer. When I bought my one, directly after unpacking the box, it wasnť able to start. I was angry, but then ve have tried to charge the battery in my friend's charmer and it worked (the battery was not completely discharged, but maybe some electronics inside was somehow blocked)
otherwise, you can try to diagnose electric circuits inside - but do it carefully, you may easily damage it!
speaker charmer
it has production defect. the HTC has knowledge of this... and is about one reparation in warranty. [[]]

I have a problem with my mda compact II and it was almost like describe.
after i tried to upgrade my pda, the update went to the end and finished successfully, the pda doesn't turn on, it shows the t-mobile image and then goes off, if i press camera button and turn on button i can see the tree colors, but what should i do now?
help me please.
use official t-mobile rom (in t mobile official page, difficult to find, get the link from the XDA-Wiki).
1. put your charmer into the 3 colour screen mode
2. kill your activesync in your PC (or just disable USB link)
3. run the EXE of the offical ROM
Do it before your battery went dead.

try leaving it off with the battery in and plugged in for about an hour to see if you can get a charge, otherwise use another battery that is fully charged. Only other way is to use a SD backup which you can then install with the power cable plugged in.
also you do not need an activesync link to install ruu rom packages. also long as your in bootloader with usb showing in the corner, the ruu will be able to find it.

I Have the problem whit de boot, is stay in tree color.
I have do the hard reset and the soft reset and donth work.
canth you help.
I have the cingular 8125
claroscuro: First of all, this is not 8125. Second of all, just flash an official rom while in bootloader mode.
RUU via SD card + only power cable plugged in
[. Only other way is to use a SD backup which you can then install with the power cable plugged in.
[/QUOTE]
i have similar problem how can u use SD RUU when power cable is attached and mda compact 2 is in 3 coloured bootable screen.
i have a fully cahrged batter but mda is not detecting battery, mda only start+ bootable mode when power cable is plugged in( battery is 100% charger in another MDA but MDA is not recognising battery.
PLZ help
You can buy an adapter for charmer in which you can insert USB cable, power cord and headphones jack.
can you please recommend what it is called as search for MDA COMPACT 2 USB cable, power cord and headphones jack on ebay doesnot come up with any thing.
Cheers

do u mean this item, i am not sure from description if it can sync using a usb cable at the same time being charged by main power source.
Have the same problem
HI, I have the same problem, and even with the battery been on charge for a full day, as soon as a try the updates it comes back saying there is under 50% charge. When I try in the sync holder with power as soon as the USB is connected it powers off.
Did you find a answer to the problem ?
Cheers

this is nothing , my friend , MY BATTERY DOES NOT EVEN CHARGE AT ALL
IT IS NOTE DETECTED AT ALL.
i have tried fooling the device by using the cradle with power supply and usb connected with pc but it neither cahrges the device nor it is deted=cted by the pc.

another possible battery calibration technique for HD7

If u have poor battery life, try booting into bootloader (tri color screen) mode by pressing turning off the phone, pressing the power button and vol down buttons together. Then charge the phone for a while under this mode.
Restart the phone by holding the power button If can't restart , pull out the battery and put it back again and turn on the phone.
Tested on nodo with the latest July firmware update.
My take is that somehow it wipes the battery stats and rebuilds it from scratch.
is it by connecting to power source or our pc/laptop.

power source...
Can't see that orange led lights when i connect charger while my hd7 is in bootloader mode...
The phone does not charge in this mode, thats why you must have at least 50% battery when you need to flash roms.

[Q] Why my SGS dont turn on?

I'm having a very strange issue with my SGS. I have ONE's 8.3 ROM and the device is functional. But, when i shut the phone down i can't turn it on. Every time I shut it down and then try to turn it on by pressing the power button, de loading circle image show up but a few seconds later the screen turns black, and cycle repeats forever.
The only way I am able to turn the phone on is to connect the usb data cable to the phone and an pc usb port where the phone has been connected before (any other port won't do), afterwards the battery starts to charge (even if full) and I can turn the freaking phone on.
Things i've tried:
Changed ROMs (CM7, MIUI, One), changed Kernels, wiped battery stats
Please help me as this is a very strange problem.
PS: is my phone is in that infinite cycle, i can enter in download mode but not in recovery
If you can enter download mode then try flashing a stock ROM via Odin.
i already try it and have the same problem with stock rom
I think your proximity sensor is not working anymore.
A friend of mine got a similar problem.
His phone won't wake up after having a call.
He only was able to turn it on by connecting it with USB or AC.
I also think you have to send it in for repair.
I'm sorry mate, but that's my solution
Well, maybe someone got a better one.
but my sensor its working perfectly i think inst it... :/

S/w mode problem

Hi,i have been trying to flash the new v20 version to my Lg P880,and i have all the drivers installed,windows enabler etc...everything that says i must do in the tutorial-i did it...
But the problem is i cant enter the s/w mode without the battery.
When i remove the battery,i hold the volume - key and plug my usb cable in,and nothing happens.
I even tried it with volume + or holding both buttons-but it just wont enter the s/w mode.
I can enter it while the battery is still in the phone,but if i take it out-it wont.
What could be the issue?

it doesn't matter if your battery is in or not. try it with the battery still inside - if you can access S/W mode that way.
If you have desktop pc issue can be your PC usb port! Logically your phone need some kind of electric power to operate in SW mode, if you use front pc port or some kind of usb hub maybe they doesn't provide enough power, and when you put your battery its working..try to plug your phone in motherboard's usb port on backside of pc case!
I have similar situation where i had huge amount of different usb devices plugged in my pc, and SW mode only worked with battery...and sometimes lg tool asked me to reconnect the phone at the moment just before flash start (even so my phone was already in SW mode and recognized from lg tool), and then i had to put battery in phone otherwise lg tool said that phone is not conected!
But if you can go in SW mode, than you do not have a problem!

Connect phone to charger and wait some time... Nokia has a battery software protection and will not turn on when the battery is completely discharged.

yes, connect phone to charger and leave it some time... after some time just press and hold volume minus and power key together until phone vibrate...
Charge and wait until your phone turn on it self,
