My is Wizard Dead. Please help

I got a used wizard today,it is a few weeks old I also got a cradle with it.
I pluged in the cradle to the USB port and the charger to power, after playing with it for 1-2 hours I placed the wizard on the cradle to charge and after a few mins i noticed that it was over heating. I removed it from the cradle right away and noticed that the battery was droping 1% every minute or so. After it was down to 27% i removed the charger and left only the usb connection and placed the wizard on the cradle again. it was charging fine, when it was up to 90% removed it from the cradle and again was droping fast.
When it was down to around 25-30% of the battery I did a soft reset and since then I can never get it to start again also the red charging light does not show.
What the heck is wrong with it? I also get a light burning smell from the bottom of the wizard where the connector is located.
Any help?
I need your lights guys.
Don't like the sound of the light burning smell, that sounds like an electrical fault. It looks like your battery has died and the wizard battery setup is well known to do this. You need to plug it into the official mains charger (not the usb one) as this has an output of 1A, enough to kick start the wizard battery into life and start the charging. You need to wait a short while though before the light comes on. If this fails try to get a new battery and try that. Any more light burning smells and it needs to go back to the supplier.
I would suggest that you send it back to replace/repair. The rapid dropping of the battery power suggest that it is using power somewhere (illegally). I've heard cases of battery caught on fire, etc. and I won't suggest you to use it anymore until you sort out the 'burning' smell.
First of all thanks for your replys.
I pluged the charger on it and the red charging light came on after a while.
charged for over 6 hours and its still red? I think after been charged should change to green? right?
anyways after all that still doesnt want to turn on. I got it to start a couple of times but only to the point that shows the splash screen with the rom numbers and then it turns back off.
Should I give it a smash across the room on the wall? done that with some other things and worked just kiding.
Forgot to add that up to the point when i did the soft reset the device was working fine except the charge drop. Soft reset was done while it was working ( turned on)..... if thats any help.

That ain't gonna do jack sh1t to it. If it can't start to get into bootloader, it can't flash....and it's not a flash issue.
Usually the red light means power but not charging - happens to my qtek 9100 when I let it get too flat and I have to remove and insert the battery while the mains adaptor is attached - others have to 'jump start' the battery by directly connecting to a PSU - I wouldn't do this with yours.
From what you have said it sounds like a short somewhere. Any signs of water damage? Warranty? What Wizard do you have and what country are you in?

I got the wiza 200 O2 xda mini S from a guy in UK from ebay. The idiot sold me a cradle for it with an adaptor that says 12V on it (Like an idiot that I am i just noticed that) but then again how am I supposed to think that he gave me an adaptor that its not made for it when it says on the back of it "for Imate - Kjam". Do you guys think thats what burned the **** out of the unit ?
dont forget that some times turns on shows the ROMS numbers and turns off.
No water damage... I think its on warranty... I live in Greece.
Might not be the cradle - it could be it steps down internally to 5v. Use a meter and check what it outputs to the phone. Warranty with XDA's are 2 years to the *original* purchaser. As they are only supplied with an airtime agreement then that isn't you.
Richard
have you tried changing batteries to a new one? Seriously, thats the easiest thing you could do right now and you could actually get results.
Ok this is what I did.
Removed the baterry from the device,
got a 12V 1 Amp power supply that I had lying around and give it a few shots connecting it to the battery giving it an electro shock.
(If you're going to try this be very carefull.<<<< DONT LEAVE the power supply connected to the battery>>>> just give it a few shots 1 second on and off.
That was it.
It started working, device turned on and now its charging (I think) yellow light is on.
I'm going to leave it on for a few hours and see what happens.
Wish me good luck. I'll let you know soon.
ok... this is what happend.
Battery is drained and its not charging due to a blown fust on the main board.
I open the phone and placed and solder a little wire over the fuse.
Still does not charge. ^%$#%$#$^%$*
Before I replaced the fuse or should i say short it the yellow light would come on for a few min and then red again. Now when I charge the battery with another external power supply the pda comes on for a few mins and then dies again. ( no charging light whatsoever).
Does anyone know where to get a mainboard for it and about how much it costs?
Asking for help again.

Hey man, sorry to hear about that.
The best you can do is to claim your money from ebay.
You probably killed it when you pluged in the 12V PSU. That's 230% of the normal Volts! Otherwise sell it for parts.
I'm in the process of claiming the money back from the IDIOT that sold it to me.
Lets see if that part of Ebay works as good.

Doubt it. Did you ask the seller for help before opening the phone and voiding the original warranty on the device?

Not a good idea IMO as now the blame is on you as previously he may have been able to get warranty service from the original vendor.
Richard
I did ask.
He is not the original buyer.
what was I suposed to do.... track back 2-3 buyers to find the original... send it to him so he can have it repaired? Anyway it was out of warranty because of the burned fuse that says that some other charger was used with it.
I had a similar thing happen but fortunately not as bad as yours. Twice now my battery has mysteriously drained completely. The last time when I tried to turn the unit on, it flashed the boot screen for a couple of seconds then poof, no more juice. When I plugged it into the USB port, nothing, no lights, no charge, no recognition from Activesync, I thought the unit was fried. I use Tmobile and got to admit they did send me a replacement fairly quickly. Before I packed up my unit I thought maybe I should plug it in using the wall charger and presto, it came on and is working fine. I have no idea what causes this but do know that if the battery is completely discharged the USB port can not over come this to put a charge on.
Same thing happened to me, kind of strange though. The charge was perhaps 70% to the best of my knowledge. I flashed it with Mr. Clean ROM and booted it up.. it came in fine into WM5, then it started the installation of the 3 progs or whatever comes with Mr. Clean.. after the second finished the unit just died *poff*. Screen blank, no responce to power buttons or any other buttons for that matter.
I've tried taking out the battery for different intervals of time, no luck. I've tried using the AC charger, no luck. No lights, sounds, telepathy or matrix ****.. it just lies there like a dummy phone.. hmm what to do. Bought it from a guy in UK (im in sweden) on eBay, don't think I will have much luck there.. even though it's brand new...
Any thouhgts?
I have had this problem - I bought a replacement battery and all is now fine. Another thread in this group states that the battery cannot charge without the OS up - so if the battery is completely discharged then it is impossible to charge through the phone. The only solution seems to be somehow to charge the battery directly - as appears to have been done earlier in this thread.
Chris
p.s. if anyone knows of another way to do it I'd be interested to hear as I'd like to revive my old battery and keep it as a spare

Dead magician...? Red light!

Hi all,
Need som urgent help. The backcover of my device is not fitting well any longer. Guess I´ve bumped it to many times...
As a result (Iguess) I cant turn on or even charge my magician!
The only thing that is happening when I try to charge is that a red light is turned on. What does this mean?
Any solution of how to get it work again?
Is it possible to buy a new back-cover? Live in Sweden.
Thankful for some ideas!
Regards Emil
Most probably the notch on the battery cover that hits the microswitch lever has broken. You will find the microswitch on the lower-right corner of the device when facing down. Put something soft but strong enough (ie. foam) to keep the microswitch in the ON postion then mount the battery cover and temporarily fix it with tape. Be sure to keep your device plugged in via USB or charger in order not to totally discharge the backup battery. If the backup battery gets depleated, then it's like doing a hard reset.
You can buy parts from ebay but I've always bought from Brando and is very reliable dealer (shop.brando.com.hk). Delivery is quite fast too.
Hi Zerimar and thanks for your answer!
Unfortunately that didn´t do the trick. Still the same red light when trying to charge. And I can´t turn it on! I am pretty sure that the battery is flat out by now but even so I would think it would load and then after a while, I would be able to turn it on.
Am really frustrated abt this!
Any more ideas maybe?!?
Regards Emil
u'd better send it to service...

Well, that´s what I´m trying to get around... Thats why I´m hanging around here
If have have my device charged via USB or charger, the LED becomes as soon as I remove the battery cover. If I hit the microswitch lever then the LED turns green and start to boot up. If main battery is removed the LED stays red even though hitting the microswitch's lever.
It looks like it's not charging your main battery or your battery is already defective. If your device is over a year old and you're still using the same battery, then its time to change it. Bulges in a battery is a sign that it needs replacement.
Before sending your device for repair, why not look for someone you know who also has a Magician or equivalent device and quickly borrow his/her battery?
I had red LED when plugging into a main charger - and then the phone reset.
Red LED + loop booting-poweroff = dead battery
If the LED is RED when you charge your device for hours
If the device tries to boot sometimes, but powers off by itself some minutes after (it means, at least, that your device CAN boot! )
Your battery may be dead, I bought a new one for 10Euros on ebay...
Those batteries are perfectly compatible with HTC Prophet or HTC Beetles (Ipaq 6515) and maybe other devices... easy to find!

Dead Exec

awhile ago i dropped my exec down the toilet......
I make the mistake of turning it on before it had fully dryed out.
I was wondering if any has an ideas on what to do.
When i plug it into a power socket without the battery the red light comes on, but if i put a battery in and reconnect it the light flickers and goes off.
Also if i use a usb lead to charge the red light just flashes on and off.
So any ideas or is it dead as a dodo..
Thanks
Yep. Take it to your local phone dealer. tell him what you have done to it.
He may be able to ultrasonicially clean the boards... Costwise not much change out of £50 or more.
Else you could sell it to me for a tenner if the case is good, as I need a new case for mine as it's showing signs of wear.

HTC HD2 Is not turning on, only turns on sometimes whats wrong? need help extremely!

Ok i got an extremely bad problem
i brought a hd2 from ebay with a fault, which was the person said he dropped the phone and the screen cracked then he replaced it with new screen and digitizer, but he said after he did that the phone only starts up sometimes, anyway i won the bid and when i recieved it i put the charger in and it turned on by itself and was stuck ar htc screen i took the charger out and the phone went off, so i put the charger back in again and it didnt turn on this time, tookout battery and did reset and hard reset and still nothing? the phone doesnt have hardspl.
so i opened the phone up and look to see if anything was lose which it wasnt and i also manged to damage the volume flex cable and the bottom buttons flex!
so i left my phone overnight and in the morning i put the battery in and put it on charge and A RED LED LIGHT CAME ON!!!! which means it was charging so i thought if i press the reset button it come on, so i pressed the soft reset and nothing came on and the red light dissapeared and it doesnt come back again?
Can anybody help me whats wrong?
Since the previous owner has dropped the phone, anything could have went wrong.
First, check the battery pins on your phone, and make sure they are straight (not bent, not eve a little)
Hi I tryed that but it still don't work, also to follow up I put my htc in fridge for 5 mins and put in usb and orange light comes on so I left it for couple of hours and after it finished charging it virbrates and screen comes on but it just stays black so I took out battery and it didn't startup, so battery is fully charged and I. Put phone back in fridge and put usb back in and orange light came on again, so this time I pull out usb cable and the light is still on??? And I pull out battery and it goes off I don't know what's wrong???? Its driving me nuts!!!
Edit - ignore what I wrote above, okay I left phone in fridge and I put battery in and then I put in usb and orange led light comes on then the phone vibrates and the htc logo screen comes up but it is frozen there and I can't reset because I have no buttons because I broke the flex ribbon. I pull out battery and it turns off and it doesn't come back on so I put usb in and then battery and nothing but I can feel a tiny bit of vibration but not as strong as before. Its soo wierd the phone only powers when I leave it in fridge.
really need a solution fast
Please guys I really need a solution, don't leave me hanging. I was going to buy a new motherboard but I don't know whether its worth it because I font want to waste money.
I can't answer your question. But I know for fact that if the hd2 overheats monsterously the processor melts off it's spot or something and the phone starts to reboot at 25-30 Celsius degrees and that could explain cooling it down lets it boot. My suggestion is to sell the phone on Ebay as SLIGHTLY damaged Hahahah!
infact thats what i done i put it on ebay if anyone wants it let me, mint condition except boot failure I don't think it the processor because I can connect to usb and it comes as qualcomm data
The phone tries to turn on because I see the vibration motor turn once but nothing else happens?
facepalm.
....
Was there any need of facepalm makes you look like a retard. Don't do it please

[Q] LG G2 Red Light No Power

Hi All
My friend recently gave me his LG G2 as it had a problem.
What happens is currently if you try and turn on the phone nothing happens. When you plug the phone into the charger the red led blinks and nothing else happens. He told me that he got the phone brand new off eBay and that the problem started after he left the phone plugged in overnight. No software modifications have been done to the phone prior to the red light issue.
After some investigation into the issue i found nothing except another eBay listing with a LG G2 D802 where the guy got water into his phone and it has the exact problem where the phone does not turn on and a red light comes on when attempting to charge the phone. The eBay listing also says that the phone was seen by a service technician who said the circuit board was damaged but is repairable
Before i spend any money buying spare parts does anyone have any idea on what the problem is and whether its worth fixing?
Thanks
Could it be that the motherboard got damaged?
I don't think the mother board got damaged. I had the same problem with both my G2's. (D800 and LS980)
I had changed the motherboard from ls980 to the d800, I connect everything, LCD, digitizer, battery,front and back camera ..etc..
I go to try and power the phone up but nothing happens..
I go to plug in the phone.(Nothing happens)
I use another charger(nothing happens.)
My phone wasn't water damaged though. In your case you could open up your phone and disconnect the battery connector, After about 1-3 minutes connect it back & leave phone alone.(don't try to power up)
I had a problem with one of the phones not having the red LED light coming up to tell nevit was charging. I switch the battery to another bezel & motherboard & it shows 40% battery level.
It definitely worth a try to open your phone & disconnect and connect the battery if the phone was charging one night.. I remember seeing a forum on here that the phone might be still on charging mode or something.

Hi,
I have the same problem, the only sign of life is a red flashing led when I try to charge it up.
My lg g2 (D802) did get water damaged tho, however I don't think it has been damaged that bad. When I found it in the watery environment it still worked, but it was quite warm. First hour or so I put in in a towel, because I wasnt home. When I got home I discovered it was dead. Then I put it in rice for two days, but now this problem occurred.
I reconnected the battery (twice) but it didnt change a thing, and now it still won't boot up...
Hopefully someone can help me (or sees this at all),
Thanks in advance
I have the same problem with my G2. I changed the motherboard after it got water damage but nothing else changed. what should i do?
Solution for blinking red error
Hello Guys,
I have the same problem like you others. 8 times red blinks, phone won't charge, PC won't recognize it, dead at all. But I found the solution. There is a short circuit on the moterboard. That can be LCD, digitizer, buttons or anything other. I have unpluged digitizer connector and BOoM!, connected it to charger and turn on with power button. So you guys can test what's making problem on your MB, it can be anythinhg. I hope that will help to someone.
Sorry for bad English.
same thing here
I have an LG G2 that I recently replaced the batter (ordered from ebay). After the install, the phone just blinks the red indicator light. When I hold the power button, it blinks 8 times, pauses then starts over again blinking 8 times and pausing. Please help.

I have the exact same problem. recently bought a new battery, because my original one is increasing in size (very strange) and decreasing in power.
When i put in the new battery the phone doesnt work if i try to turn it on. When i connect the battery to the charger its just the blinking red light...

I'm having the exact same problem...working ls980 phone using to restore my D801 motherboard....but have no power.
When I plug the ls980 board back in it works again. Last time my D801 board red led blinked 2x but wouldn't startup with its own battery. How did you fix it?
It is the battery. either the cable is ripped or the battery is at 0 volts I've just tested this on my LS980 using my analyzer to fully charge a battery externally to 100% made it work fine, please check the battery cable its very thin and very easy to rip without knowing it. (I work at a battery store) Hope this helps some of you!
A solution for 8 Red blinks:
If you have 8 Red blinks when you change the screen the Solution is:
The two metal joints from two small boards (besides volume and power button) that connect to the motherboard they should be completely attached to the connector.
