PLEASEEEEEEE HELP T-MOBILE MDA III (QTEK 9090)

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,

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?

Need Help W/ My Imate JasJar. please read.

Greetings! First Off I'd like to say xda-developers rock! I've searched high and low for a solution to my prob and cannot quite find one. My Jasjar has a very hard time coming on. Most of the time a soft reset will not do the trick. I bought a brand new battery with no luck. If you take the battery out, wait about 4hrs or so, and put the battery back in sometimes it will boot to winmo and work fine for about 15min. then the screen will fade leaving blue lines across. After that it unresponsive even if you try to charge it. The battery meter in the phone reads 100%
Things I tried/done:
READ THE WIKI
reflush with several different roms.
bought a new battery
check the internal battery
shocked the internal batt with a 1.5 AA bat like mentioned in a post
updated/downgraded boot loader.
I'm at my wits end with this. I love the phone but i might have to sell it on ebay.
PLEASE HELP ME!

what internal battery are you talking about and where did you get the new one?

I got a new external battery from ebay. i used the voltmeter to test it to make sure the correct volts are putting out. and it was

UPDATE: When I plug in the charger, the light stays red for about 1min then goes off. I double checked that the battery was in secure while it was glowing red. Any ideas?

Dead P3300 due to battery?

Hi all,
My two year old HTC P3300 has gone dead and I suspect it could be the battery. How could I know for sure? When it was new I upgraded to WM6 and apllied the corrupt SD patch because it was crashing sometimes when I would access the SD.
After that it has been working flawlessly for over a year except for battery life which has been getting shorter and shorter for the past few months. I turned off bluetooth and wifi and still the P3300 was only able to go for about 24H with normal usage (just four or five calls, a few reminders and no GPS).
All of a sudden a couple of weeks ago it started just turning off by itself when using simple things like card games. I could feel the battery was pretty warm and pressing the power button would do nothing. Only a soft reset would work.
Then a few days ago it finally decided to die. I was playing Freecell with the battery at about 80% and it turned off by itself but now even soft reset won't work. When I plug in the charger the orange light wont turn on althoug the battery does get a little warm.
The only thing it will let me do is start a hard reset but nothing much happens. It says to press send if I want to return the P3300 to the original factory settings. I accept and for about one seccond it shows:
Format FAT partition!
Format complete!
Then I get the HTC boot screen and some red letters that say:
IPL 1.36.0001
SPL 1.36.0000
and then nothing else happens. It just stays like that for a couple of minutes until it turns off by itself. After that I can't even do a hard reset unless I put the phone on the charger for a couple of hours.
To me this looks like it could be an exhausted battery but how can I confirm this without buying a new battery? I checked with a tester and I get 3.07V DC but I can't seem to get any amp reading (maybe I'm doing it wrong).
Please any ideas would be welcome. I love my P3300 and I hate the idea of having to change.

Hi!
I'm experiencing the same problems...
Tried new rom, sdhc update cab, format sd to fat32, try another sd, etc...
Seems that the phone works more or less well if there's no sd card (maybe because it need more juice from the battery?), and even better, if I can say that for a phone..., without sim card too.
It worked more or less today only with sim card on it, but when there was an sd card it keeps blocking, hanging and turning off with difficult turn on situation.
Can someone help us?
Thanks!

Hello both.
It can be frustrating waiting for help (and you might have found an alternative solution) but I'll say what I can.
If your Artemis can be operated more normally whilst charging but fails quickly under battery power, that certainly suggests a battery problem.
Batteries are consumables but hard to test (although some shops can) - try your local retailer?
My spare battery is a Sanyo ARTE160 rated 3.7V 1,200mAh.
On the reverse, 4.2VDC is printed amongst chinese characters and it actually measures 4.16V off load. I'd think 3V far too low.
There's clever technology behind the management of these LiOn batteries because both over charge and over discharge can damage them. Their life is more determined by battery chemistry and charge/discharge cycles than age.
One caution - measure voltage by all means...
BUT
DO NOT measure current with a test meter to a battery - particularly not a LiOn battery - because it amounts to a short circuit. Current can be so high as to blow the meter fuse and in cases of sustained short circuit or over charging, the battery can swell or even burst dangerously.
I'd think a replacement battery (via e-bay?) far less expensive than paying repairers to confirm the battery was the only problem.
Hope this helps

Hi!
I bought a replacement battery from Ebay.
All seems to be OK yesterday at night until today by noon.
Today, in the middle of a phone call, the phone stalls.
After a reboot and some hours later, the phone keeps crashing and crashing and, sometimes, it doesn´t turn on...
Will try now to upload an original rom and see what it does.
Regards!

This might have happened because difficulties whilst using an impaired battery left a legacy of part-saved data, registry and file corruption problems.
The outcome would be good to know because battery problems can/will affect us all eventually.
Also, a brand new battery can need a few charge/discharge cycles to bring it up to best condition.

I also got a new batery from ebay and unfortunately it still doesn't work. Behaviour is exactly the same as before.
I suppose this means it is hardware related. Do you suggest opening it up to see if there is anything loose or broken that could be resoldered?
Thanks,

My p3300 went blank and I had the take the battery out to switch it on again. Took it to HTC and they had to replace the insides of the phone. When I got is back the batt. Only lasted for a day and it use to work for 4 days.

FS Pocket Loox N520

Hello. I have a very big problem. My Pocket PC, a Fujitsu Siemens Pocket Loox N520 has been bricked. It occured this way:
I purchased a new battery (quality one, for FS). I started it, it went fine, I connected it to my PC and borh linux and windows had seen it as device. Then, after a few hours I wanted to hard reset it. Tried 10 times, no succes and now, when I try to start it it get's stuck at the image with the climbing people, no booting, no usb recharging. I really don't know what to do and I need your help/advice.
I tried the following. Hard reset, soft reset, battery replace/removal, linux won\t see it with lsusb command, tried to reburn rom but it's not found as device.
Thank You!

These Looxes (I have N560 with extended battery) sometimes get stuck if the battery voltage is too low, i.e they are nearly out of juice. If you have the original battery, have you tried running it from that? Whichever battery you use, make sure it is fully charged. It could be that the new battery had not had a full first charge? It may even appear to be charging but has not fully held its charge and has been running down. I have had bad experiences with Cameron-Sino batteries, which appear to be working but in fact are not holding their charge.
I am clutching at straws but it is worth a try? These are pretty rugged devices. I would not give up hope yet.

Exactly Sir! The battery was not fully charged when the problem occured. I will try what you said and post the feedback. I also hope is not dead, yet.
Thank you and if you have other suggestions I would be glad to hear them.

No other suggestions. You should charge it on the cradle though and not be tempted to try to turn it on at all until it has had a few hours of juice/charging. It should not make any difference but to be sure use the cradle and not a USB socket in the lead. The mains charger has a greater output capacity than USB supplies and it is likely to give a better charge rate. Be warned, the N520 may not show any signs of life at all while you are doing this long charge. I would leave it over night and try again to hard reset it, or indeed even use it, next morning. Most new batteries, even LiIon ones, need a longer fist charge and it is not recommended that you use them until they have received their first over-long charge.

I tried a full recharge on my pda, over night but no success. Still, when I power it on, it doesn-t boot. I don.t know what else to do.
I think i should rewrite the ROM. Can anyone help me with that?
Please...

Ummmm it does sound like you may have a hardware problem?
The following site has in the download section the Fujitsu Seimens ROM burning program.
http://translate.google.co.uk/trans...snum=1&ct=result&prev=/search?q=newplow&hl=en
Someone could point you to the ROM image for your N520? Newplow's site has software which can switch devices in the FSC range but I cannot remember if the 520 is catered for?
I wonder if it is stuck on the climbers boot screen whether the burning progrram will work either, as you have to use a PC which can communicate via USB with the device, even if only as a "guest"?
Have you also tried ensuring the device is completely powered down by removing the fully charged battery for say an hour then re-inserting and trying again to start? Are you sure the battery is fully charged - have you measured the voltages on the battery pins with a voltmeter?

Ok. I can't even burn the ROM, the device is not recognized on both linux or windows. Nothing. Anyone knows if its possible to repair it or it is forever briked and I can throw it away? Or maybe keep the parts? GPS receiver ?
Please respond. Thanks!

Just had the same problem today. I was flashing my N500 from WM6 to WM5 and the god damn setup crashed. Now I can only see the climbers and thats it. No hard reset or boot screen combinations work

Something spooky going on here!????? Two crashed Looxes...
I repeat, if all hard and soft resets have failed, the only remaining test is to completely remove the battery and any power source for a long period of time, just in case some residual charge lingers in the electronics/chips. I would suggest several hours, perhaps overnight. Then care fully re-insert the battery and try again. If this fails, I am afraid your device is well and truly bricked.
The only other little trick is to look for the proper operation of the little switch which resets the device when you slide the cover back on. On the Looxes this is operating by a small pip on the back cover. You should try the device with the battery firmly pushed in and the cover off. Then try delicately (it is very tiny and delicate) to operate the switch. Look at the screen while you operate it? It is a simple spring loaded micro switch. It should have a similar effect as a soft reset, taking you back to the climbers screen. Worth a try. I have had problems with it putting the device into a odd "stuck" state from which there seemed to be no way out with normal soft or hard resets.
There must be an engineer somewhere who might attempt a repair????? I was an electronics engineer some years ago, but have long since hung up my soldering iron, otherwise I would offer!

Help needed, dead BA

Well, as always XDA developers is what you use when noone else helps you, my freaking BA is acting strange:
1. The phone doesnt turn on when the battery is in. Tried charging the battery 100% and switching it on but it just doesnt turn on.
2. Now when I place the BA in the cradle, the phone turns on but it just keeps on restarting.
Somebody please help me out.
The phone worked fine until when I tried to tape the body and the battery with cello tape, that is when it went dead, and now I have the two problems mentioned above.
Help me guys,
Thanks a ton all.

try a new battery.
and check the battery lock..

You might have messed up the pins connecting the battery to the device. Also, the little lock for the battery could be damaged as well. Finally, your backup battery could have died also. Hopefully this will give you some guidance towards the root of the problem. Chef has a disassembly guide in his tutorial.

well thanks guys for those responses. My updates are:
1. Since the battery was over 3 years old, I have ordered a new battery (yeah i know i should've checked with another battery first but damn noone else i know uses this phone). So till my new battery arrives I just got to wait.
2. Regarding ezthunder's replies... well I checked the battery connectors on the phone, they seem to look alright to me (physically), how do i test them to check if they're alright, pls help.
Also, regarding the backup battery, damn i would now need to search the net to find a new one.
The battery locking clip seems to be fine and is locks the battery in place, if this is damaged, I'd be freaking damned to try and get this one fixed.
So guys, any DIY suggestions to get these things fixed would be welcome as I dont wanna brick my BA, freaking just put in a new LCD digitizer.

Let us know what happens when the new battery arrives and we'll go from there.

well my battery arrived yesterday, i put it in and tried to switch it on but alas nothing. Charged the battery full and put it in but no start up.
Just the same old problem, phone keeps restarting when in the cradle but nothing when out.
Help me guys............

Well still no response from the forum, however, I have a few updates and hope this could make it easier for someone to figure out the problem:
A strange thing happened yesterday -
1. when I disconnected the flex cable of the buttons and the keypad on the front panel from the main board and put the entire thing on the charging cradle. IT WORKED. I mean it didnt do the restarting problem, it worked perfect. However when I took it out of the cradle, it wont power on. While it was on on the cradle, i checked the internal battery and it showed 100% charge, which means that the internal battery is good.
2. Now back when I connected the flex cable to the connector on the board and power it on - nothing happens and when put in the cradle - the same restarting issue right after the statup screen.
So based on the above - what are your conclusions, is there a problem with the flex cable connector but then in that case it should start when taken out of the cradle.
And yes, its a new battery that I just got. So guess its not a problem with the battery...
Help me guys. I really want to get back my BA... it was such a pleasure to see it working in the cradle with mentioned in point 1 above.
PS. I left it on the charge for the whole night yesterday but no change when taken out of the cradle - just desperate to try anything to get it to work.

Judging from this, it seems that there is a problem with the motherboard itself. I could be wrong, but that's what it looks like to me. You can probably get a new BA from Market Place. I have seen a few members selling them lately.

*bump* still waiting for some good soul to help me out with the prob... i really dont wanna lose this phone...blue angels are real beautiful babies to have around...
