totally dead wizard after battery drain - 8125, K-JAM, P4300, MDA Vario General

Hi,
That's the first time I am not able to find in this great forum a solution for a problem with one of my 2 wizards (i love this machine...)
Yesterday, one suddenly did not power on. I knew that the battery was pretty low, so I guessed was just discharged. But once I plugged it at home to the wall charger, no amber light appeared, nothing powered on! When I replaced the battery with a fresh one, nothing changed... and when I tried the "bad" battery with my second wizard+wall charger, I confirmed the battery was almost empty (2%), but worked fine.
I tried to plug the mobile to the computer, but nothing... to soft-, hard-resets... the bootloader reset... but my wizard did not respond electrically or electronically to anything... any idea what could be happening? any possible solution? I do not remember exactly which rom I was wearing now, if that matters... probably a FariaWM6_realthing_crossbow
thanks to all in any case

Maybe out of sight accident
why you leave alone your lovely wizard and so aprecciated mmmm....
its xtrange but as you say i think this kind of forum may helps you with software... took it to a cellphone repair center... they has multimeters to know where does the energy stops... maybe a little electronic component has burn it down. or try the not original and official wall chargers withj specific mhz and amperage, try something more hard.
hope i help you

more news
After being overnight without the battery, this morning I tried a "resurrection"
I just put back the battery, did a softreset, and it worked!... really!? no... just the first two screens (HTC welcome and machine tests) It did not go forward, and a second reset it did not work either... now it's again like yesterday, just dead
I think there is something else than just an electronic problem, but who knows. I recommend you not to let the battery too low!

Charging a completely dead Wizard battery
Delapena,
I've had this problem a bunch of times with my Wizard (Cingular 8125 branded version). I was able to get it working again using the instructions of a VERY helpful person(s) who I want to give credit to but cant remember right now (sorry in advance) so just FYI this works for me, but the credit goes to the original poster (will edit later if I recall).
Easiest method (if available):
1) Locate your STOCK 5vdc/1.0A wall charger.
2) Remove stock battery, put it in a ziplock bag, place in freezer for 5-10 min or so. This should minimize the internal resistance of the battery to boost VDC across the terminals (in case you ran the battery very, very very dead).
3) After the battery is good and cold, put it back in the phone; DO NOT PRESS THE POWER BUTTON!
4) Plug the 5vdc/1.0AMP STOCK WALL CHARGER into the phone.
5) Charging indicator (solid amber LED) should light up after 5-10 seconds with no other indications (no screen, no beeps, just solid amber LED ON).
It's my understanding (may be wrong) that the 1.0amp wall charger uses/supplies 5vdc one one or more of the mini-usb plug pins than the standard USB->mini-usb cable used for standard data-transfer on standard USB-spec devices. Also, the wall charger sources a full AMP of current at 5vdc, as opposed to the 0.5amp each USB host IC is allowed to source (e.g. the USB host IC on your motherboard/front/back of computerbox).
...reply to this if you want the comprehensive method. Ill research if above doesnt work / you dont have the charger. Swamped at present though; if you need the full blown recharge-the-battery-from-the-stoneage method ill look it up---dont want to give you invalid info.
If you dont want to wait (i'd understand, been there), try searching around a bit if you havent already found what your looking for.
Reply back if you need more help, otherwise, good luck and replace your battery with a new one asap!
Cheers
(again, no credit to me on this one, got this solution from somewhere else on the forum a long while back...credit to original poster!!)

Sir,
I didnt read what you had already tried. My wizard is rebooting constantly as well. My thought is that my battery is so old that the battery charging chemistry is so out of whack that the battery charging / voltage sensing circuit is all sorts of confused as to where the (really old worn out) battery is on its charging curve.
I'm guessing that my phone is rebooting because the battery fails to supply adequate voltage at x.xx amps of current draw to the phone's internal voltage regulator. When the IVR cuts out, the phone poops its pants.
I'm currently looking for a battery replacement myself.

more... but less
Thanks for the help, brhestir. But did not work for me. Actually, I tried with the 3 batteries I have, which actually work OK in my second wizard.
The only thing I am able to "slighlty" reproduce till now:
1) Wizard remains several hours with any battery plugged
2) I put the battery back
3) I switch it on or do any kind of reset
4) Just sometimes, the machine starts up, but gets hanged up after the first screens
5) most of the times, after this... the screen turns white slowwwwly, till it switches off
6) only once, I managed to get the bootloader screen, which stayed like that with any problems... but the computer cannot connect to it, so impossible to change the rom.
Next step: to dismantle the machine (prior step before throwing it through the window)

wow i just ran into the same problem today.. my battery was low tried to plug into the cigar lighter but the fuse was blown due to another object i had plugged in so i didn't get a chance to charge it, the phone was fine all day until i left work it was completely dead.. no amber light for the charger.. have you had any luck?

hi everyone,
i solved this problem by creating a sort of bypass for the battery...
i bought a special battery used for some circuits experiments which is 4,5v..
i connected the + and - with the phone contacts, with the battery plugged...turn on the phone until the orange light is on and leave it until charge is full...
this is cause phone needs a minimum of charge to start recharge circuit...

Yes the same problem on every post
The thing of cooling batteries is an old but knowledge charging fast option but it brokes your performance batt drain so i recomend a new full battery ok? is the only way or...... charge the one you have fully fully.
and try again! tu plugin the batt once at time and again and again it wouldnt boot cause its too low to begin the OS and let you charge with the wallcharger... to charge with the wall or usb you need a bootable and functional OS ok?
hope you can find a way to charge your batt at least sufficient to boot the OS ok?
bye

well good news! 20 minutes in the freezer + 5v + 1a = win

CONGRATS!!!!!!!!!!!!!!!!!!!!!

Repair a Hermes

All,
I'm looking for a company which is able to clean and repair my HERM300 device.
It got wet and now when I want to charge it the led turns red.....
When I leave my device on a warm radiator it works and I can use the device...
But it seems to fail when it gets colder....
Any suggestions?
Cheers and thanks,

I would like to add something, may be you already know, to red led knowledge. I have a car charger (just plain chinese USB charger with usb cable) When I connect my HERMES I could have 3 conditions: orange (charging) Nothing (not charging) or RED (?). If I soft reset, with charger connected, I ALWAYS have orange, after Windows Mobile screen, But if I disconnect and reconect I have ALWAYS No Light
connecting hermes to charger without battery also enables red light.
Charging Problems - Red Light of Death (RLOD)
Battery Charging Problems, in particular the RLOD so called because the phone refuses to charge and the red LED shows, indicating that the battery is NOT charging.
Background
Problems with charging are not HTC or Windows Mobile specific. Similar if not identical problems are reported across many models and platforms. The issues centre around the state of charge of the battery and the interpretive circuitry in the device and charger. Typically a device will show a Red light rather than an Amber charging light. (NB: RED LED always shows when battery is absent or fails to charge). see also http://forum.xda-developers.com/showpost.php?p=1076879&postcount=28
Getting the battery to start charging once this light is shown is not always straightforward and is as unpredictable and temperamental as priming a water pump (those that have done this will know what is meant). In other words, and to put it crudely, you need to kick start the system. Unfortunately those that have managed to do this have usually tried lots of things before it starts working again. This makes it hard to be absolutely certain about the solution other than perhaps the last 4 or 5 actions taken.
Those that have managed to recommence charging have not reported that the problem recurs on a frequent basis. (possible exception of in-car charging issue). This issue requires patience and time, (time maybe critical, it is possible the issue would resolve itself perhaps as charges dissipate within battery and circuitry involved). However the following points seem probable solutions and were thought to work by some who resolved the problem.
Failure to Charge (Red LED Lit when charger connected)
Causes of this problem are unclear, but in practical terms events leading up to this issue have included:
1
Leaving the phone on charge overnight (possibly but not necessarily with certain programmes or connections running) It seems a fault occurs in the charging system, which causes the battery charge to drain rather than increase. Resulting battery charge is very low. (Another Blog will be added concerning an Active Sync issue which can cause the battery to drain over-night through repeated connection attempts)
2
Through heavy use or not re-charging often enough so that the battery is permitted to reach a sub 10% charge (not precisely known but likely to be very low)
Possible Solutions:
A
1.) Remove battery
2.) Connect the phone to the charger or USB
3.) Insert the battery while connected to charger
4.) Red light should turn Amber
5.) Soft Reset
If this does not work immediately it is suggested that the battery be removed from the phone for around 1 hour and the above steps repeated.
OR
B
It has been found with some phones charging can be re-started by:
1 ) Remove battery
2 ) Connect charger (Optional. I would try this potential solution without the charger connected the first time I try this. If it fails to work then I would repeat the steps with the charger connected)
3 ) Holding the battery, line it up wiith the phone's battery contacts.
4 ) Move the battery rapidly on and off the contacts
6 ) Repeat the above until the Amber charging light comes on. So after perhaps connecting/disconnecting 20 times, insert the battery properly and give it a few seconds to see if the LED turns Amber.
7.) Soft Reset
NB: I have seen two reports where those attempting this report a fairly loud "pop" sound following which the phone began to charge. However in one case the person reported that they then had subsequent problems of signal reception on the phone and thought the popping sound may have been related to this.
OR
C
If your problems remain after trying this a few times you could always try the following to manually charge the battery a little (enough to let the phone charger circuit detect the battery is present when you put it back in)
1) Remove the battery from the phone!
2) Take 3 fresh AAA batteries in series (total 3 x 1.5V = 4.5V)
3) Connected the (+) wire to (+) on the battery
4) Connected the (-) wire to (-) on the battery
5) Hold this in place for 60 seconds.(possibly longer you are trying to charge it enough for charging circuitry to recognise there is a battery installed.
6) Put the battery in your phone
7) Switch on phone and start charging (via USB)
Hopefully you will get the Amber charging light.It may be worth repeating this a few times if not successful on the first try.
The electrical contacts are all important, poor contacts will render this a worthless exercise.
I leave it to you to decide how you connect the wires. If you have no other means you could enlist the help of someone to hold the batteries and wires together while you connect to the phone battery! Warning - Do not connect a mains based transformer to the battery with an incorrect charge rate (mAh) and voltage (V). Any attempt to force charge using mains transformers could be extremely hazardous (explosive). Only a qualified/competent person should attempt to charge the battery in this way. Similarly, even if you are using batteries to do this task, do not leave them connected for more than a few minutes and stop immediately if either set of batteries become warm.If the problem persists:The final resort - a new battery.

Very good article Mike, I linked it on the Hermes problems wiki page
i just want to add my 2 cents to this, there was an earlier post on here that mentioned the car charger deal where it wont charge unless you turn the phone off, plug it in, then turn the phone.. right now i am on my 2nd 8525 and it has done this, but its not only the car charger (cheap belkin car charger) but it sometimes does this with usb cradle i got from ebay, i have opened the cradle and there isnt anything different, its a straight usb connection, hmm except now that i think about it there is a blue LED, but it shouldnt be drawing enough current to cause this. Also i have a motorola charger in my office that i used with my wizard (i believe output is slightly different, if i remember correctly its a .5 amp where as the HTC charger is 1 amp) but it also behaves in the same manner... the only 2 methods that work constantly and consistantly of plugging in without turning off is either the factory charger, or a regular usb cable on the pc..
just seems weird since all of these problematic situations worked fine on the wizard and i believe they both have the power requirements...
let me toss another idea in the fire here on this, something that just occured to me... i wonder if this somehow could be related to the factory installed driver for this. what made me think of this is how the battery meter only goes by 10%.. could this funky driver be the source of the problem?

If your cradle is not connected to your PC, or if your PC is off while you see the behaviour you described, then the likely reason is that pin 4 of the Mini USB connector isn't grounded on both your car charger and cradle. See here for more details.

8525 (hermes) Charging may be voltage sensitive
I have noticed with my new 8525 (USA Cingular model of phone) that it came with a 5.5V charger. Whenever I connect to a 5.0 V USB source charging the phone is very "iffy". Given that the standard for USB is 5.0 V (4.75 - 5.25) there is a problem with the design. My question for the HTC crowd is can this be fixed via a ROM change or are we stuck with a bad design?

Since you got it wet, it is most likely not covered by the warranty, these and the numbers for out of warranty repair if you live in the U.S. I know that for cingular, you have to ship it to them yourself, and they will charge you a $28 diagnostic fee, before telling you how much is costs to fix the problem (if they even can)
heh here almost the same, providers are charging ~$29.5 USD as diagnostic fee but they are more polite, they first tell estimated costs, and only ask for the sum if you (usually) don't order the repair but need back your phone
Hellejoep:
if you are willing to send it abroad (inside EU) and you are either not need "overnight return" or such nonsense or cover the extra costs such operations really need, you may contact me. no diagnostics fee or anything such (though you will have a small loss.
about the charging problem:
the same issue occurs also in Wizard/Prophet, and Charmer (compactII) as well. though not in Magician, even so that they share the exactly same battery.
I believe it must have something to do with the charging controller. I don't have a disassembled unit at home with me now, but I suppose it should be a crap companion chip from Texas, to be interfaced with the ever-worst TI OMAP platform
(sorry, no hard feelings, pals, but someone using such one as an actual everyday phone must have some sorta mental problem )
strange battery issue
Hi all,
I've a similar issue with any charger.
It happened first with car charger (one cradle with an usb output): sometimes it charged, most of all it charged only when power was off.
Now I cannot charge with any method. (those described here: battery charging problems)
Usb cable (it's not original), original power supply, even with the y cable.
When i try to charge, it drain battery (i tried with a new one) and amber led blinks slowly instead to be firmly light.
There's anything I can do?
It's a SPV M3100 buyed two months ago on ebay.
I tried also with two roms WM6 official release ITA ver and Schap's 3.54b ITA ROM WM6
radio 1.48
Any suggestions?
Herm200/tytn problems
hi to all,
i read most of your post on possible problems with this PDA (HERM200/HTC TYTN).
i'll try to spent some few words to explain the story around my pda.
i live in italy and i bought the TYTN on december 2006 and for 6 months with his software problems i used it day by day in my business activity, untill one day, it falled down the ground from my and with all the leather cover (bundled with the pda, an hard black belt cover); then i took it and picked up a telephone number from my addres book and then putted it in charge for all the night; when, late in the morning, i took it, i noted that there was still the red light of the battery indicator and then PDA didn't turned on.
i tried to make soft/hard reset but nothing.
I carried to the italian warranty service of HTC and after 7 days they deliver to me the PDA in the same state that i carried; on the technical report there was: pcb damaged, battery connector pinouts damaged, pda not Repairable - out of warranty.
i thought: "i have had a lot of care for this PDA that still look like as new one"
and now i have a 700€ of unusefull PDA.
Last day i finally decided to open my PDA to find broken pieces and more.... but nothing.... i observed really well: NOTHING of wrong.
Now i will to know if somebody of you, can suggest me something to revive my PDA or suggest me any service center (affidable) in europe (not like the italian one) where to send it for maintenance: I DONT WANT TO THROW OUT MY PDA!
Thank you in advance for your attention and patience.
ps: sorry for my english, i hope it will be comprehensive.

If I understood you correctly, your TyTN still works - it just cannot charge the battery, right?
Then, probably one of the cheapest (although not perfect) solutions is to get a cradle that can charge a battery outside the TyTN (like this one on eBay). You will have to power down your TyTN, remove the battery and put it in the cradle every other night or so, so it's not very convenient. But it's cheap. Maybe you'll want to keep this as "plan B" in your mind while you look for a more perfect solution.

Hello!
I had also a battery charging problems with my MDA Vario II (TyTN; Hermes; HERM300):
1. Charging from the AC mains supply with the original miniUSB 5V charger: no problems.
2. Charging in the car with the non-original car lighter miniUSB 5V charger: it was charged only when the phone was OFF; no charging when the phone was ON.
3. Charging with the USB-miniUSB 5V cable connected to the notebook: it is charging only when the phone is OFF; no charging when the phone is ON.
So I asked myself: what is the difference between all these three cases? They are all miniUSB 5V power sources... And I found out an answer: It should be a matter of the USB current amperage.
Original AC miniUSB 5V charger delivered with the phone is 5V/ 1A. When I have bought the car 5V miniUSB charger with the 1A (one amper) amperage - there is no problem with car battery charging anymore... ;-) The phone is charged either way: ON or OFF.
But is it possible to charge the battery correctly from the notebook? I think not, because I have no influence on the current value from the 5V notebook USB.
Previously I had MDA Vario (Wizard): in this phone there were no battery charging problems... I wonder why the are some with the Hermes...
Take care,

This is not correct. The problem is well understood and has been discussed several times.
The key is that your device tries to sense what it is connected to:
- if there is USB data traffic, it concludes that it is connected to a computer. It will then negotiate the current (power) it can draw from the USB port with that computer.
- otherwise, your device checks if pin 4 of the connector is pulled to ground. If yes, it concludes that is is connected to a dedicated USB charger, and starts charging, consuming as much power as it needs. This mechanism seems to work only if the device is on - and sometimes not even then (bug?). I guess the mechanism is implemented in software, so it can't function when it is off.
- otherwise, it doesn't know what it's connected to. Could be a computer in stand-by that didn't power off its USB ports or something. Your device concludes it may be unwise to start charging (could, for example, drain the other device's battery).
The cheap after-market chargers do not connect pin 4 to ground (pin 5), so your device doesn't charge. If you are really good with a soldering iron, try connecting pins 4 and 5 of the charger's USB connector, and you'll see that your device will start charging with it.

Thank youu Tadzio,
but my PDA is DEAD !
I still don't try to charge the battery separetly.
The reason is that when i carried the PDA to service i leaved the PDA and Battery: i dont wanto to believe that service dont check the battery !??!?
However , i will try to charge the battery separetly and then i will know you the outcome.
Thanx and Cheers

Mda will not turn on or charge

hey guys, my mda will not charge or turn on. when plugged into a/c the indication light does not come on. i have switched batteries with my other mda and still unable to turn it on. i have done searches but have not found any relevant info. does anyone have some insight?
No charge
I have exactly the same problem...
My phone was charging and my washing maching caused a power surge and the only thing that seems to have been affected is my HTC Wizard! I've ordered a new battery so I'm waiting for this in the hope that this is the problem... If not - HELLO INSURANCE!
I'm running into this also. When I plug in the charger, the LED turns green, then red and thats it.
anyone? may have to do some brain surgery on the mda
You haven't told us anything. What were you doing before it quit just turning on? Have you tried to do a hard reset on it, soft reset, or put it into bootloader? Were you trying to flash a rom when it quit working? Was it on an original rom or custom one (and which rom was it?). Did you upgrade it in any way (load software)? Did you do a soft reset and it quit working, or did it just die while you were doing stuff? Or did it just not turn on the next time you tried to use it?
Like I said, you haven't told us anything other than it won't turn on with your battery or another battery. Information is a good thing
For me...I didnt do anything. It was on and sitting on my desk. The battery was a bit low. I went outside to check the mail, came back and it was dead. I tried turning it on, the boot screen came on and then off...never to turn on again at all.
No custom roms or software or anything. I couldnt find my wall charger so I took my old razr charger plugged it in, nothing, LEDS wouldnt even come on.
So I took it to a Cingular store and they had an OEM charger there. They plugged it in, the Orange LED came on for a second, then turned red and would just sit there. Not even turning on.
But what ROM were you on? THere were numerous issues with the early Cingular (and other) ROMs where once the battery got below a certain percentage it would not charge anymore. There are tricks here and in HowardForums for how to jumpstart your battery (using a 9V battery or a wall charger with bare wires). Can't say if thats what this issue is, but it might help.
So you said you took yours to the Cingular store. Did they replace it? You didn't finish your story.
i know, im sorta interested in what happened
OK here's the solution.
First of all, be aware that the MDA can NOT charge unless the OS is fully loaded. If for whatever reason your battery gets fully depleted, you have to do the following (it involves ruining a 5 $ cable and doing some surgery):
- first, go out and buy a new USB-to-mini-USB cable, unless you have 2 already (or one and the original charger)
- take out the battery
- take the USB-to-mini-USB cable, cut off the mini-USB plug and expose the four wires
- strip the red (+) and black (-) wire and twist the copper ends of each wire
- now CAREFULLY attach the right wire to the right connector on the battery (so + on + and - on -) and tape it there so it stays firmly on
- put the cable in your (running) PC or put the charger in the wall socket
- let the battery recharge for an hour or so, then put it back in the Wizard and reboot
- now when it is fully rebooted, you need the second cable to charge your Wizard completely, the way you're used to.
Worked for me! I've kept the ruined cable, just in case it happens again.
Good luck!

Luckily enough an old friend of mine had an 8125 that finally broke to crap, so he gave me his battery. I popped it in, voila! Not only did it load, but it comtinues to charge. I was worried the phone was bricked.
But this is definately a battery issue. Thanks for all the help and info guys. It's good to know this thing wont charger unless the OS is fully loaded, didnt know that.
May I just check, is this charging issue (when the OS is loaded) only an issue on the 8125's? I have an o2 Mini S and just as a check powered it down by holding the power button but while in this state if I connected it to a charger the orange LED still came on to indicate it was charging but in the off state.
hey guys sorry i did not respond earlier i have been away for sometime. well my phone was working all night but when i woke up it would not turn on. i plugged in the charger into the wall and none of the lights came out. took the battery from my broken screen mda and still did not turn on. the phone had the xelencin 2.26 rom update. programs i had installed were:
spb shell
spb diary
spb pocket plus
battery status - overclocked @ 195 i believe
most programs were installed on a 2gb minisd card.
again the phone was working fine the night before and upon waking up it owuld not turn on or even charge. i am currently at work but i will try out the previous suggestions as soon as i am home and will post back.

OK here's the solution.
First of all, be aware that the MDA can NOT charge unless the OS is fully loaded. If for whatever reason your battery gets fully depleted, you have to do the following (it involves ruining a 5 $ cable and doing some surgery):
- first, go out and buy a new USB-to-mini-USB cable, unless you have 2 already (or one and the original charger)
- take out the battery
- take the USB-to-mini-USB cable, cut off the mini-USB plug and expose the four wires
- strip the red (+) and black (-) wire and twist the copper ends of each wire
- now CAREFULLY attach the right wire to the right connector on the battery (so + on + and - on -) and tape it there so it stays firmly on
- put the cable in your (running) PC or put the charger in the wall socket

i see 6 connectors on the battery and left is red and right is black but there r 6 connectiors so which 1 i should plug in the neg and pos sign is like right in between..so can u upload a pic so i can see?
The pins that you need to connect it to are the end ones, the red wire goes to the one thats at the end with the plus symbol, and the black at the opposite end with the minus symbol. I just tried it and it works great.
doesnt work, maybe i bricked my phone

I just recovered two regular batteries and and extended battery using this process. Too late though. I have another battery coming in from WM Experts. Any way the process is flawless and the charge time would depend on how long the battery has been low. Another possibility is may be the battery has run its life.
Fixed it!
as stated elsewhere the charger has to be 5v ish and 1A i'd tried other ch1argers nd everything nd then i found a charger 4 my old phone which was an spv c550 which was 1A plugged that in and after a couple of seconds the good 'ol orange charging indicator came on.. after which it booted up perfectly! so happy it's working now hope this helps some1!

Dead Battery HTC Wizard

Hi all, for those of you that have experienced a totally dead battery you'll know the pain it is to get it going again. I have recently had this happen and decided to post a fix on here.
Lesson #1 Dont let your battery die completely, if you get a low battery alarm, turn your phone right off till you can charge it.
Lesson #2 If your battery dies completely, just throwing it on the charger wont charge it. This is because the Operating System looks after the charging. If your OS wont load, your battery wont charge.
FIX:
After trying various methods on the net, I found a surefire way to jump start your Wizard so you can get it charging.
You'll need : 3 x AAA batteries and 2 lengths of wire and some tape.
I cheated here, I managed to pull a 3 pack AAA battery setup out of a regular Panasonic cordless phone which saved me having to piggy back the batteries.
1) If you dont have a battery pack, you'll need to piggy back the batteries. + to minus on each one so that you have 3 batteries connected to each other with one free + and - side. Use the tape to keep the wires from moving around and getting loose.
2) Remove the battery from the phone.
3) Put a wire from the + side to the top connector of the phone battery connection ( top gold pin, right hand side of phone nearest to the power button )
4) Put the other wire from the - side to the bottom connector of the phone battery connection ( bottom gold pin, right hand side of phone nearest to the camera button )
*** There are 6 gold connections sticking out on the side. Make sure the wires only touch the top and bottom pins. Bend them round if you have to and clip them if needed.
5) Try the phone and it should switch on now. If it does, push the battery back into place while its loading.
6) As soon as you get to the today screen, plug your charger in. Wait about 1 minute and check its charging ( from the battery icon under seconds ).
7) If its charging remove the wires from the AAA battery combo ( in case they explode or something ).
Hope this helps the next poor soul that didnt have time to charge their battery before it died completely. And thanks to all the posters that have helped me out with my problems. Long live the Wizard
While this is a good post, it in not entirely true. If your battery completly dies, you can infact use a standard wall charger that outputs 1AMP or more of power to charge it with, even if you phone wont start. The charger that is included with all HTC devices outputs 1AMP, so they should all be useable. Good post otherwise though!
Thanks ashasaur. When I posted this I did not have access to a standard wall charger. However looking at getting one just in case this happens to me again. HA I hope not.
Thanks for all that advice. In desperation, I have just bought a new battery and was relieved to see my Prophet come back to life, having, yes, let the battery run completely down. (I am away from home, where I left my charger as the Prophet seemed to charge quite happily from a USB port)
If 3 AAA batteries work ok (~4.5 volts), wouldn't it be a bit safer just to connect them to the dead battery for a while, as described above, to give it a bit of a charge, rather than risk the phone, or isn't 4.5 volts enough? Greg
buy a 4.5v 500ma adaptor and it will work
Earlier I was afraid of dead battery and use to turn off my kjam but later I got an idea and purchased one 4.5 v 500 ma wall adaptor($1 only) and cut the end socket and use it to give initial charge.
Earlier I was so much worried about my battery that had to put it in charging point where ever I find a usb port but now seems Kjam battery knows that's why haven't died for 2-3 months even though sometimes I forgot to charge it in night

Great idea. Just tried it with an in-car USB power adaptor, but it didn't supply enough oomph. If you follow pawanmehta's advice, you might want to check out this site - USB pin out and lead details - for the correct leads to wire up.
A quick look around the internet suggests that mains to USB power adaptors are available at £4.85 (UK) or $15 USA but I expect a proper search would turn up cheaper items. Greg
It works with a O2 XDA Mini S, but it didnt work at first time: I have to put the cable with the 3-battery-arrangement and the 3.7 1400mAh battery at the same time, it's looks like that it wont turn on if the pins are not pressed, but well, I succesfully boot and now i'm charging (i remove the 3 battery arrangement).
And, I use 3 AA Duracell batteries, I tought it's the same than using 3 AAA, 'cause they use the same voltage (1.5 for common, and 1.2 for rechargeable).
Best regards, and thanks a lot MattyZee, u have my blessings

hey everybody...
i read the thread a few days ago and thought...okay good to know but that will never happen to me now that i know that it shouldnt...
now...a few days later...of course it happenend...
soo...i tried everything. but the things are complecated to do alone...with all the wires and then pushing the power button and installing the battery again...
so i had to give up...
but here is another way how to do it...
it is already beein mentioned i think...
use the 3 battery combo, 2 wires at both ends, take out the dead battery and put the - wire to the pin at the very botton (the bin at the longer end) and the + at the other end.
hold that just for about a minute (i think i just holded it for 10 seconds but a minute would be better maybe...)
and then put the battery back in and it should start...
oh and i tried to use a 1400mA wall adapter and it didnt worked...
but try to avoid that...
it is not a nice situation seeing youre wizard dieing like that...
and at first i thought it is not the battery...i thought it is broken...
so avoid it if possible...
thats it...
What is length wire (sorry if it's a idiotic question)
please help
btw, I have O2 xda mini S.
And can I use 3 AA batteries????
thanks a lot,it worked
once again THANK YOU
You guys are geniusses It started, but when it started I put the charger in it fro my laptop and waited a while (removed batteries) then i saw it was charging but when I was waiting some more it yust fell off !! So i started it up again with the AAA's and then putted charger back in and i was using the phone, I saw it was charging and I looked @ lvl and it kept on saying it was on 0 % :s Then i thought let me wait a while and i stopped using it so it fell off again, what did I do wrong twice ?
Thx
A 9v Battery (The type you find in smoke alarms) does the job as well.
ONLY connect it for a couple of seconds, but repeat about 5 times then connect it upto a usb data lead and after about 10 seconds it should kick in.
After its been charging for about 30 mins turn the Wizard on.
Have succesfully used this method on 3 Wizards now and it works every time!
Don't Forget To Put The Battery Back In Your Smoke Alarm!
Exceptional
Thank you. I have a Kaiser that I love, and was just handed a Wizard that wouldn't even start. This post let me boot it and start the charge.
Thanks.
Apologies for bumping an old(ish) thread but I've tried this jump start method and seem to be having no luck with it.
I've tried the methods suggested, using 3 AAA batteries didn't seem to do a thing for me, but I've had a slight result using one of those square 9V batteries; the camera flash comes on and the screen lights up but wm doesn't begin booting up (the screen just stays blank but lit).
I've also tried attempting to give the battery some charge using the method mentioned earlier but that too doesn't seem to be working either.
The battery in question is brand new (one of those extended ones with a higher mAh) and I'm assuming it's arrived with zero charge in it.
Does anyone have any suggestions?
(incase anybody is wondering, the wizard boots up fine using a different battery which is charged)
edit: if it's of any relevance, the wizard's a g4.
edit2: I've tried charging it with the wall charger but all that seems to happen is a red light flashes once every 5/10 seconds and the screen flickers on then off
Update: After numerous attempts at jump starting, my wizard now refuses to charge whatsoever.
The light flashes orange (I did follow the guide posted on the wiki about that but it had no effect) but it comes up saying it's charging onscreen, however it simply doesn't charge (the battery life just slowly drops).
It's the same using either the wall charger or usb.
I did try taking the battery out/doing a soft reset/doing a hard rest but to no avail.
Would I be correct in assuming my wizard's now broken?
I'd just donated my blueangel to a friend too as I thought I'd no longer need it, but now i'm left without a phone
I've found a standalone battery charger on the internet for around £10 or so, I might give that a try. If it works, I'll have my wizard back, albeit without being able to charge it while it's switched on. On the plus side, it would eliminate the need to jump start it ever again though.
wizard resurrection...
This problem is quite a hard time for the wizard users...
I know many users with 2 or 3 wizards in the closet because they just died, and there are none powered batterys around...
I hope this can help someone, somehow...
WIZARD RESURRECTION
Props to all!
undertuga
How did u make out with the battery issue? I have the same prob and the light on the camera lights up but i can't get it to charge and i'm using a new battery any suggestions would be helpful. Thanks
Just to repeat a comment made by ashasaur 12 months ago. You need a 1amp charger. Although someone had success with a 500mA charger, that wouldn't work for me, whilst a 1000mA (1Amp) charger worked to recover a completely discharged battery.
A new battery should not have zero charge. NiMH batteries do not like being left around fully discharged and, to the best of my knowledge, are not supplied discharged.

charging problems

Hi guys asked it once before in battery section, but no replies.
My HD doesn't charge auto, when I press the on button the battery charges for 15 sec. tried a new battery same result. I know it Physicly charges, when I charge the phone by pressing the on button a couple of 100 times (really 100x) I get 1% charge. So don't say 'HTC phones only charge when on', cause I know.. Tried a Hard reset 2 times no luck. meanwhile my batt. is dead. So I can't try other firmware.(need 50% charge min)
(chargers are fine)
In short, anybody ever heard of this problem before with other htc models/HD ?
Physicly it charges, so would a firmware change help?(then I need to get a standalone charger/new battery with charge).
My last option is to bring it to HTC but that would take a month
Sorry for number of words on this lazy sunday.
Update - firmware update doesn't work.. next is radio....
no ideas anybody?
Hi,
Unfortunately I dont know much other, then charge the battery in another HD up if available (maybe u can ask in a telephoneshop or so) and then test the Firmware changes.
Is the same if you charge it via PC/USB?
thx for the reply, did just that, changed Rom/radio, official and dutty's rom's, no change. No problem sync. have atleast 3 usb chargers none of them work. When connected to usb cable 2 lights blink 1 green 1 amber one after each other. just like a new message/ low battery even when battery has 50% I get the same light patern, (this is a new battery).
The thing is when the battery is completly flat it stil charges for 15 sec then it turns of. So when I charge it 15 (x15 sec) times or so I'm able to turn the device on again. But when it has (some) battery power the lights start blinking again and I'm completly unable to charge the battery.
The phone is almost 2 weeks old and charged normaly until I checked the "don't charge when connected to usb" option in the power menu. ??!
Then I think you wont get around, to send it back for repair.
have you tried to charge it with a wall socket or is this only when you usb to pc charge??

I never charges, wall/usb doesn't matter.
I just used another HD battery to restore everything to default, So I'll guess I'm taking it back..
Thx anyway.
exact same problem
Did you get anywhere with this problem? I have been strugling with the exact same thing... I have tried all the same things as you, only sometimes it seems like it might be the battery contacts.. I havent been able to consistently get it to work but sometimes if I firmly press the battery against the contacts it will behave normally

Nope tried the contacts but they work fine, battery just won't charge, do your light also blink? (on the power button).
I haven't found any info on the web?!?:S
Problem is solved.. had to be sent back to HTC for repair, it took less then 2 weeks (door to door) so that was pretty fast. They swapped the mainbord, so I got my 'old' phone with a new imei.
So don't waste your time with software up/downgrades. It's a hardware problem.
I had a very similar problem.
Once my battery died some app hung system all night.
No charging at all wall charger and USB 1 day each and so many manipulations. The indicator blinks momentarily and then nothing. I didn't try (didn't know) the key presses like Dogtag. Did a hard reset still nothing...
Then thought about charging the battery with external (Lion) charger before sending for repair. I also shorted the battery compartment pins momentarily. To my pleasant surprise everything back to normal
So far no problems after that though I never drained my battery to zero.
Looks like something to do with corruption in battery calibration data - may not be in ROM?? who knows??
fantastic. can u elaberate?
hey Cragee
I did't understand what u did. Can u try to explane it to me one more time?
I'm realy excited about a posible soulution
hooray

Only two things I did can matter -
1. Charging the battery after taking it out (with a battery charger*)
2. shorting pins in the battery compartment after taking out the battery. (Warning: not on batteries)
Don't know which of the two worked.. No harm trying both anyway.
* U need a Li-ion battery charger - else invitation for trouble including fire and explosion.. These are available in electronics shop at a reasonable price.
Short-circuiting the battery pins... seems to work
I had the same problems with my Touch HD the last few weeks:
- stopped charging after a few seconds
- didn't charge at all (nor the wall nor the computer method, on or off)
- well... it charged sometimes but randomly, keeping it on a wall charger (on OR off) for a night could bring it back to 20% and then rapidly back to 0%
- no charging indicator in the screen while turned on
- blinking orange and yellow (?) light even while turned off
- charged almost never to full and 'jumping' from high to ultra low capacity when turning it on & off
So before bringing it back to the store i tried to short circuit the battery pins as suggested (while the battery and charge were unhooked) like the thing you would do to clear the CMOS memmory of a PC in the 'old days'
And for now it seems to work, at least the charging icon is back online!
I'll keep you posted on longer term results!
Update: I switched to the wall charger and the HD died again??? Now it's back on the computer and it seems to charge fine... why????

When u say "shorted the battery" do u mean, turnoing phone off, taking battery out, connecting the 3 battery connectors with a wire for a few seconds?
....so what does shorting mean??

I thing so. You should circuit the pins WITHOUT battery. In any other case it may occurs damage on the telephone
Dogtag is right... it's defenitly a hardware problem
As posted before...i had the same problem with my touch HD, charging was a pain or sometimes seemed impossible. The phone was repaired twice.
-First they replaced the connector - no succes.
-Second time the replaced the motherboard, and everything was solved.
So imho it's the mainboard of some machines, i still wonder if it's a factory problem or a 'fried' chip of some kind after a bad charging procedure? Bad USB car charger of some kind?

[Q] HTC HD2 running nand android will not turn on after battery died

Hey everyone been using this thread for a few months now it's so useful and I appreciate all the help. I know this has been posted before and I tried all the steps listed in the other thread but last night I let my phone die and when I plug it in it just boots up until the dark forces team screen before it starts over again i tried all the steps listed to get it to charge it just seems not to work. I was able to get into the magldr screen if I plug it in and hold volume and power off. From there I choose to power down and as long as it stays plugged in the orange light comes on but when I try to power it on nothing happens. Any advice would be greatly appreciated. Thanks so much
you cant charge it powered off without winmo, simple.
2 options, borrow battery long enough to flash wnmo on your phone, use your phone to charge battery, or put battery in another winmo hd2 to charge enough to start android. (or, let it sit for an hour or two, they sometimes recover a little charge, perhaps enough to boot. Boot with the usb in, cos ability to charge kicks in about half way thru teh boot process.
just to add a third option to my last post, , i let my battery die stupidly today, completely dead, , took an old usb cable, took the end off, black wire to - and red wire to + on battery, plug in usb cable, bite nails and worry for 1 minute, enough charge in battery to power on phone and boot enough for actual charging to start!
phewwwwww.

heh, not that brave, i didnt do it till id read about a hundred posts of people doing it on various devices.
@bakse, whats to explain?
get a usb cable,
cut the usb end off,
strip off the silver shielding,
find the red and black wires,
bare the ends,
attach the ends to the battery,, red to +, black to - (it says on the battery which is which)
plug in the usb cable.
After a minute, remove the wires, and try the battery in the phone, and hope it has enough power to start to boot and start to charge.
I read a fair few posts where people were holding the wires to the battery by hand, it is after all only a few volts dc, but i just wasnt that brave and went for gaffer tape.

Ha ha I have been a electrician for 15 years now and I can tell you with 100% assurance that the very small voltage that it takes to charge the battery of any cell phome will never ever affect you in any kind of way. You know I had often wondered if you could charge the battery in this fashion but was not completely sure as my I do not have a full understandimg of yhe iom bstteries yet.

hehe, i did 3 years as an electronics tech in the RAF, (long time ago) so im not usually that nervous around electricity, but i was last night, , generic 3 pin usb charger, generic usb cable, stories of batteries bursting, ANYTHING could have happened!
Ive tried it again today on an old dispensable htc elfin, held it for 5 mins, which is far longer than any posts ive read. Battery got warm, but not worryingly, and when i booted the elfin it had 2%, and managed fully booting plus ten minutes use, and id drained it completely before starting.
Im glad ive tried it, and now i hope i never need to do it again.
I just accidentally let my HD2 drain the battery, but this is the first time it hasn't come on. I did the USB cord trick and it seems to juice the battery, but when I finally got to the menu me being so caught up in the excitement that my phone wasn't bricked and that I could get it running again forgot to plug in my phone to be charged and it died again... Now I am using the hacked up USB cord to charge my battery, but is doesn't seem to charge it very fast and after about 10 minutes of letting it sit I get to the boot screen in Magldr but the battery dies mid boot. Now my question is should I leave the battery to be charged with the red and black wire USB trick and how long can I let the battery charge like that will it be fine for a few hours? Thanks for your replies in advance.

I don't know if it would be safe to leave the wire connected to the battery that long. To be safe I would only leave them connected to the battery for 15 to 20 minutes 30 minutes max. I would also monitor the battery making sure it is not getting warm/hot or that the batterry does not start to swell.As either of this things are signs that you should disconnect the wires.
Well it worked I got it charged to 5% and it took forever, but when I put it in my phone and it booted it said it was currently charging, but when I woke up dead again...
Charge with wall charger, not via PC,, the current of PC charging is way lower, so for an almost flat battery it may not be enough to both charge and run the phone.
Ive been doing this usb cable hack/trick what ever u wanna call it for a few days now my usb port is completely busted and ive got wp7 on it struggling to find anyone near me that will fix it as im not brave enough to take the phone apart and replace the micro usb port

I spent couple hours last night after my phone accidently died and was unable to turn on even charging with wall charger, I read about trick with cutting usb or charging cable and attaching wires to the battery. Finally, I found great solution by myself. I simply connected phone to my car charger and in less than 1 minute it started Android and after couple minutes I was able to move my phone back to the wall charger
actually you can charge the battery with whatever you have handy.
I charged phone batteries with anything ranging from wires cut off from just about any li-ion phone charger (older nokias, samsung and se preferable), solar panels, other batteries (3 standard aaa alkaline batteries in series will do the job also - almost no risk to phone battery) electrochemical reactions (the best one, getting electricity from mustard using copper and zinc electrodes - also worked but you need 6 "custom made" mustard "cells" ), any sort of usb port etc
My choice depended on whatever i had handy at my disposal at that particular moment.
I also powered up phones with empty (or if i suspect them to be dead) batteries by placing 3 aaa rechargeable (ni-cd or ni-mh.. NEVER USE primary-non rechargeable batteries or any sort of alkaline/carbon based chemistry) batteries in series with the + and - leads over the ones in the phone but WITH the original phone battery connected (it won't work if you simply supply the phone with 3.7 - 4.3 volts.. the center phone battery pin is needed).
They all work and for a one time quick emergency charge, it will be fine (just don't make a habit on doing these to often).
