faulty XDA 2

Hi, Can anyone help?
I plugged my XDA 2 into my home pc's USB port using its cradle. I noticed it began to over heat, now the the top righthand power recharge light stays on (active) all the time even when it is not in its cradle, in addition to this that battery dies very very quickly e.g 15mins.
I have not been able to find any fault codes relating to the yellow light ( this should normally show only when the phone is charging.) I have tried updating the ROM and also a new battery but the problem remains.
I'd be really gratful for some advice.
thx
If it overheated it is either a short on the cradle, a short in the pda connector, a short in the battery or too much voltage. I would suspect the first three, sounds like the battery is now cooked. This is a warranty issue I think.
Do you think I could repair this my self maybe a blewn fuse or somthing ?

Qtek 9100 charging problem- NOT battery issue..please HELP !!!

Hello Gentlemen,
I have charging problem with mu Wizard Qtek 9100... its not battery issue I have 2 working batteries...
The phone starts only when the charger is not pluged in..
Otherwise RED light is shown and the phone refuse to start so I need to remove the charger and the battery and then put the battery back so I can start the phone...
When the devise has started already I can plug the charger but the Windows is not showing ORANGE light and is not showing charging....
The device acts very wired and is turning off with no reason...
This happened when my charger burned up while charging my device...
Now I have no sound,the device is SIM locked and is turning off sometimes for no reason....
I believe it is a hardware problem I guess I need new mainboard?
Please advice if this could be a software issue....
The device is G4 IPL/SPL 2.26.0001
Please advice,
Thank a lot...

Battery problem
Hi,
I know old post, but it may help somebody.
It is possible that your windows has switch off the battery charging circuit for some reason.
You MAY be able to get it working with the following trick:-
You need 3 x 1.5 volt AA batteries, some wire and 2 pins
You need to join the batteries together in series (i.e. end to end)
Next make a negative lead from the negative of the battery pack to one of the pins.
The make a positive lead in the same way.
Open the battery cover of your Wizard.
Connect the USB charging cable.
Put the negative pin you have just made into the gap between the battery and the charging pins in the Wizard - MAKE SURE YOU ONLY CONNECT IT TO THE PIN NEAREST TO THE USB PORT.
Now comes the tricky bit - take the positive pin you have just made and touch it on the charging pin which is NEAREST to the power on switch.
If all goes well the charging light on your Wizard should turn orange indicating that it is charging.
You might have to try this a few times, I was never sure if you had to keep the external battry connection on for any length of time or just a quick connection would do the trick. I suppose it depends on the state of the Wizards battery.
This is NOT my work! I do not want to take credit for something that is already documented on this site as it helped me get my battery working again.
Regards,
John
thanks a lot!
saved my wifes phone. Is this problem (happend twice already) something that I can address with a new rom, anyone knows?
I also have the remove the battery go back to Feb2006 issue. Device is off warranty by a few good years. Is it something an experienced electronics person could try (without destroying the phone that is...)
Cheers

Worked for me too
I had just bought a new battery for my Qtek 9100.
This one:
sku.23974 at dealextreme.com
My 9100 had been dead since 2006 (because the battery was dead ...)
And i got a new phone.
but i tought it was to good to throw away, so i bought the new battery.
But i did let it run out of battery, and it would not take the charge.
but this trick did the job
Thanks
Hi all,
Just wanted to sign up to say thank-you - I chanced upon this forum while seeking a solution to the same problem.
I'm happy to report that the 'jump-start' works perfectly!!
I actually used the slightly different method, described in another thread on this forum:
Take a USB-to-Mini B cable. One that you won't need ever again.
Cut the Mini B end off and strip back the outer casing. Inside is a wire mesh and within that a foil lining. Pull these both back.
Now find and strip the black and red wires. The wires are thin and this is a fiddly job, especially if you have large hands, so this works best if you screw the exposed wire strands up into little balls.
Remove the battery from your Qtek 9100 (or whichever model it is). Pay attention to which pin goes to which contact and so identify which ones are the positive and negative contacts on the battery - It is described above in Heinkeljb's post.
Now, plug the USB into your PC (which should be switched on and running) and connect the black wire to the negative (and red to positive) contact on your battery.
Hold for a good 30 seconds.
Now reinsert the battery into the phone and attempt to charge.
You may need to 'jump' your battery a few times....
Once again, many thanks to teh lovely people here for saving my beloved Qtek 9100!!!!!

Elfin won't charge at all

I got my elfin for about 3 years now and today it stopped charging. It won't charge at all with any usbcable nor the wall-charger. The led doesn't turn on. I think the usb jack is broken, but all the pins seem fine. Does anyone have any idea what to do?
If you say the USB jack is gone? did you try conn ur elfin to the computer? is it getting detected?
remove the battery, wait for few minutes, put it back (DO NOT TURN ON ELFIN) and put on charge.
If the USB jack is really broken then you can use a universal battery charger and transfer your files and activesync via bluetooth (only slower)

That didn't work. The computer doesn't detect it at all, I've tried several USB cables.

Well yes, that is the only thing I could think of, but I have none of those. They are fairly expensive to try if you're not even sure.
May be that light is not working properly.
Jus chk whether u see "Charging" in Power settings available in settings -> system.
If it says charging then ur light might have a problem.

I can't check anything, the battery is empty. That's why I think the USB is the cause and not the battery being dead, because it was already near empty when I saw it 'alive' for the last time.
I have the same problem.
Is the battery broken or the phone?
tried another battery
same result
now i'm waiting a tattoo
omg...currently my elfin behave the same way...unfortunately i don't have any other battery to try on
is it possible that your elfin one day just completely stop working? no life whatsoever???
i just can't charge my elfin at all...and yes the battery completely gone
what to do...what to do... *sigh
My Elfin did this last year. The problem for me is the contact pin used for charging in the mini USB jack on the bottom of the phone was squished.
If you look at the bottom edge of the phone with the screen facing the ground then you should see 5 contact pins along the top edge of the mini USB connector. The contact pin on the far left is the charging pin. The contact pins are springy. To fix mine, all I did was use the point of a small pin and gently pried up on the charging pin so it was more exposed.
Hope this helps,

Same problem on my side
In actual fact, when I got my fist elf, it only worked for a month then the screen stopped working. A quick stop at the distributor and a new unit was supplied. The new unit lasted 3 days and would not charge. After spending many hours swapping cables and trying other chargers and batteries, i came to the conclusion that the charging circuit had been damaged. I had the device replaced with another brand new elf and lo and behold, 3 days later, it wouldn't charge again. I took all I had back to the distributor and had everything replaced with new ones, from cables to charger to phone. I got home, flattened the battery with video playback then charged the phone again. To my dismay, it refused to charge. The broken device was returned again The distributor got so sick of seeing me for the same issues, they took my kit, and replaced it with a new elfin which has been working perfectly till today.
My guess is that the HTC devices have a very low tolerance to electric fault or spiking through the USB which causes the charging circuit to malfunction. All in all, my elf was repaired twice and replaced 6 times with new units in the first year alone. My elfin on the other hand may not be the most feature rich phone on the market but has certainly been my favorite.
Hi all,
same problem here. The power-pin just broke off. I'll try to mend it and report here.

Hi
You emailed me on this as well. You also gave some more info regarding the battery connectors being broken from the motherboard.
If the gold battery connectors have come off the motherboard then they are almost impossible to reconnect. You see, the motherboard on the device is what is known as a multi-layered board. There are connections that run between the layers on the board. The board cannot be split so that you could re-solder the battery connectors. Most often the battery connectrs split off between the layers where it is impossible to re-solder them.
If you are very very lucky the connectors have split on the surface and there might be enough of the wires on the surface of the board to have them re-soldered, but I think the chances are very low for this. You may also find that the on-board fuse has blown. This is a tiny component, but really it hardly matters unless you can be sure you have fixed the battery connectors!!

Is the vibration motor supposed to be soldered to the motherboard?

Hi,
Please can anyone tell me whether the little connector on the vibration motor is supposed to be soldered to the motherboard or does it just touch at a certain place?
I've already posted another thread about having replaced the battery but it doesn't seem to charge.
Without going into details all over again, a local repair shop replaced the charging port last week - my phone was returned in seemingly working order but they had assured me a bulging battery was OK. I charged my phone but the battery was draining quickly, which was what led me to research a bit more and discovered how dangerous it can be so I ordered a new one.
In the process of fitting the new battery, I discovered half the screws in my phone missing, no copper tape, plus there is no black rubber cover over the charging port & vibration motor as is shown on the guide for replacing the battery on the fixit.com website.
So I'm wondering if the small square 'connecctor' (?) part of the vibration motor ought to be soldered to the motherboard or is it just normally held in place by the black rubber cover? In my phone now, the 'connector' doesn't stay touching motherboard so I'm not sure if this would affect the phone and stop it from functioning or would it just mean the vibration wouldn't work?
Would this affect whether the battery could charge or not?
(Incidentally, I discovered that the the battery connector was upside down compared to the pictures in the ifixit.com guide (the red wire was nearest to the battery instead of the black wire being nearest) so I was hopeful that by correcting it to match the picture, I would have solved the problem but unfortunately, it didn't make any difference. When I connect a wall charger, the screen just flashes and when I connect it to my laptop, it just gets a blinking white led but nothing more. It seems strange to me that it wouldn't make a difference - is it like a usb-c cable in that it can go either way round?)
The battery seller asked for photos of the new battery in my phone and has now offered to replace it - is this likely to make a difference or is the vibration motor not being attached to the motherboard the cause of the problem?
I'll be so grateful for some help.
