PLEASEEEEEEE HELP T-MOBILE MDA III (QTEK 9090) - MDA III, XDA III, PDA2k, 9090 General

Hi Guys,
I put my T-Mobile MDA III (same as qtek 9090) on a cradle and after 10 minutes the screen turned off and the red light appeared on a top right corner. Now the device couldn't be turned on again. It looks like a completely dead device. Could you please help me what to do?
Is that a software failure or some other problem?
Please please please give me a hint. Is there any schematics that will help me in repairing the device? What is a cause for that failure?
Thanks in advance,
...MpegTv....

try to hard reset by pressing power and soft reset button

I've tried with hard reset and also with placing the device into bootloader menu with camera+record+power+reset and still nothing happened.
It is completely dead !!!

we have had this problem a few times with our blue angels at work, bad connection with the cradle seems to suck your batterie dead, we swapped batteries and pda works again everytime, This is the problem we get monthly that leads to dead looking pda's, exept that a batterie swap allways works,
ps
the batterie we swap with works too its just been drained.

Hi guys,
I discovered the cause. Something's wrong with my battery. After few minutes on a cradle the device turned ON and then reported BackUp battery VERY LOW, please recharge or replace.
What is a backup battery? Is that a main battery foor some other battery inside of device? How can I replace that backup battery.
When the device is on a cradle the backup battery is on 25% and the main battery is 0%.
What do i have to do beside charging?
Regards,

Blue Angel Not Powering Up

Hi,
I just changed the screen, that is identical as the original one, for my blue angel, that was down for a couple of months without charging. Now when I try to charge the device it is showing me a red light on the charging led and not orange as it used to and as a result it is not powering up.
Do you have any idea what might be wrong?
Regards,
Michal
Battery is gone.. replace it.
Hello again!
I have a question regarding powering as well...
Can I power the battery without a running system?
anyone knows?
cheers,
krztf
well youcan charge the battery only in cradle's battery holder
elaborate pls
hi xplode!
i am not sure if i have understood you correctly, maybe may question wasn't that clear as well.... sorry! so just to be sure...
i wanted to know, if it is possible to charge the battery of the BA without having a running system (rom, wm) on the ba!
is this really only possible in the cradle? not with a normal synccable or charger?
edited to ask: is it possible to do THIS with the cradle? or cable? or both? is there really a diference between them?
forgive my ignorance!
krztf
It is possible to charge a battery without a running OS on your BA if you remove the battery from the body of the device and slip it correctly into the rear charging slot of the cradle (also means you can have a spare 2nd battery charged up.) If you don't have a cradle, then you're SOL, eh?
Whether your device can charge it's battery without a running OS you should try it yourself and let us know!
Still with the problem...
Hi, an update on my initial problem.
I received a replacement battery but the problem still persists.
i.e. When I place the device in the cradle it still lights up red LED.
Actually the battery is V20HR instead of V18HRT however this should not be a problem as it has identical specs except it has higher capacity.
Any ideas\suggestions what else could be wrong?
Battery Specs are as follows:
V20HR - http://www.varta-microbattery.com/en/mb_data/documents/data_sheets/DS55902.PDF
V18HRT - http://www.varta-microbattery.com/en/mb_data/documents/data_sheets/DS55802.PDF
Hi
I just had the same thing happen - not so fast with the changing the battery thing - It could be that the onboard battery is flat - leavve it in the cradle with the battery on for a long time and see what happens Thats what I did and eventually it worked - I know it makes no sense but it worked

Hi,
Thanks for the reply however the problem is that I replace the on-board battery, pre charged.
I have not changed the main battery because it charges properly in the cradle.
Regards,
Michal.
Try putting the PDA with the battery on in the cradle and leave it a while - if it doesnt fix it take it out and put it back in a few times - worked for me and device is normal again
Kind regards

please help! DEAD BA! Any ideas...

I awoke this morning to find my BA (still plugged to the chrager) with no green light. it would not power on. I tired to remove and replace the battery, nothing. i tried soft reset and hard reset. when i put it in the cradle the light is red for a second, then goes off. I cant seem to get it to power on for anything? anyone have an idea?? please help! thank you
im glad no one wasted time responding. apparently the charger i was using drained the batteries. even though i got a red light when i set it in the cradle. after some time all is well. no data or settings were lost.
I think, You have some troubles with power converter in your BA.
It responds for conversion 5vdc->3,7vdc for battery charge and 3,7vdc->2,5vdc for pcb powering.
Best regards,

I think, board or rom error

My Orbit is dead

Can anyone help me please.
I've never had a single problem with my orbit until today when it suddenly died. I needed to swap it's sim card to another handset, so I pressed the power key until the shutdown warning, tapped yes then removed the battery and sim card. Then I replaced the battery and cover, minus the sim, but now my Orbit wont power on. Its completely dead, no LEDs lit or screen, placing it in the charge cradle does nothing either.
Can anyone please help me with this. Any ideas would be gratefully received.
where are u?
i had this problem once and it was really strange, i had to shake the battery a little and tap it a few times when i placed it back into the phone, never really figured out why it did it, but i sold the phone to my mate and he says he has never had this problem with it?? strange!
oops double post!
Try cleaning the battery contacts and the ones on the device.

Generally, a red light is some kind of hardware failure. However, it could be a failure of the charging circuit.
Try a different battery and see what happens.
Battery controller or motherboard down... you will go to service
i think your batrry is die!
Before you do that. Try using another charger.
Red indicator means that it's not charging.
Batteries dont die that fast, FYI.
How do you fix the circuit failure ,ive got the same prob but mine keeps restarting when i put in the cradle ...?
qtek 9090 show only red indicator when charging
So guys, any solution how to fix the problem with constantly restarting device in the cradle??? And suggestion how to power it on whithout the power supply??? BTW Tried with different AKB, no success!!!
Plug it in usb cable without battery first, and put battery in.
The battery needs to have some charge on it. Try cradle to charge it a bit before.

i have had the same problems and so has someone else:
http://forum.xda-developers.com/showthread.php?t=390509
I'm not sure how to resolve this i've just been looking on this tread to see if it's updated with a solution.
I found the cause of the problem was when your flashing or updating the exteneded ROM with a flash card or mtty.exe and you disconnect before 100%. for example if the battery runs dead or reset before completion. when it happened to us we were flashing about 250+ devices and four were dissconnected before 100% by some idiot who should have been working with us. we have had to right these devices of and broken. But if there's a solution it would be good to know.
thanks
elliott
i wasent doing any flashing or upgrading it was sat in the cradle charging up and when i woke up it was dead hope some one has a solution
i am pulling my hair out just spent 4 hours looking at the forum for answer to my ba but no look does any kind person who knows anything about the ba know how to revive a dead one thanks
