[Q] Charging problem

Hey all,
It seems my HTC HD2 is unable to receive any kind of charge. I've used a different usb cable, my roommate's myTouch 4G cable and a friend's HD2 cable, and they all cannot charge my phone as well. My phone doesn't recognize any cable that is being plugged into it. I've made sure I'm in the right USB connection setting, checked the little 3 gold prongs where my battery receives (electricity?) from the phone to make sure those aren't situated in an odd bent position, but alas nothing. Could it do something with the actual part on my HD2 that the cables plug into? Phone is currently dead and I have no phone and am out of warranty. Is it a part I can easily replace?
Thanks for your help!
Edit: It seems the HD2 was launched on March 16 so I'm a couple of days past the 1 year mark fo warranty. Do you think I could persuade tmobile or HTC into replacing my phone even though it this slim out of warranty?

Does your lex still show that the battery is charving when you plug your HD2 up to your charger? If so you may have a faulty battery. If not then it could be a hardware or software problem. I suggest you buy another battery and see if

Nope, the chord isn't even recognized. It's as if nothing is plugged in when in fact something is.

Sounds like a broken microUSB port. Unnless you have a warranty, you're out of luck. To replace the port, you'd need a whole new mainboard.

Yes if your HD2 is not recognizing the USB cable then yes it sounds like you have a bad mini USB port on your HD2. You can try a hard reset if you want to but make sure to back up all your personal information first, but I kinda doubt it will do you any good to hard reset. You will have to get the main board replaced if this is your issue, wi h I believe it is. You can either find a cell phone repair shop or do it yourzlc ic you feel comfortable enough doing it. replacing the mainboard requires no soldering as all the ribbons just plug in. You just need to be gental with everything as you are working on it.
Now to get you by until you can either fix the phone or just to be abale to harvesting the battery for day to day use. You can by a external charger. Or you can take a old USB cable or buy a cheap USB cable and cut the end off of it. Strip it back a little and the zrip back the red and black wires a little. With a little tape attack the red wire to the positive(+) battery terminal and the black wire to the negative (-) battery terminal. Then plug the cable into your wall charger, don't worry the oltage comming out the wires is very low and will not hurt you, in fact you can not even feel it. They are marked on the battery. I do suggest just using this as a very temporary fix until you can vet an external charger or get your HD2 fixed as I do not know if this may be detramental to your battery with long term use. Also I give credit to Senior Member Samsamuel for this idea as he is the one I learned it from.

I contacted HTC and they confirmed the phone is still under warranty. The problem is I'm running CM7 on my phone so I'm asssuming when they start it up and view I have a 3rd party ROM, they'll void my warranty. I would rather fix it myself personally but I don't know anything nor do I really want to touch/pay for a new mainboard. But if my phone does get it's warranty voided, I'll have to pay either way. I think I might just go ahead and buy an external battery charger until i figure out what to do

magldr wont let battery charge when phone is off.
No fault with phone, dead battery and user error.
Use another hd2 that isnt running magldr to charg ebattery, OR use friends battery to flash to winmo and use winmo to charge battery, OR take an old usb cable, mini or micro, cut end off, find red and black wires, connect red to + black to - on the battery (the markings are on there faintly) and plug in to wall charger for a half minute or so then try start phone with real usb cable plugged in. should be enough charge to boot far enough into android for the charging to start. If nothing at all happens, then maybe there is really a problem.
You can hold the wires on by hand, you wont feel it, or i used tape.

stock ROM. download it, extract the .NBH from the .exe, stick the .NBH on the SD card and rename it to LEOIMG. Hold volume down + power when the phone is off.

may i repeat, just to confirm you considered this before you go about getting it repaired,, , if the battery is flat and magldr is installed, the phone wont charge.nothing will happen when you plug in usb.

[Q] dead battery help!

Hi guys, in need of a bit of help here.
right, having not realised what i had done, i pulled the battery whilst on charge before i pulled the charger. my current situation is that now the phone is stuck on the loading bit. the version of android i have comes up with "droid" then goes to a red eye like thingy whilst loading. it keeps looping that screen over and over.
after a quick search i saw my problem could have been bent battery connector pins, but alas they are fine.
after another search i reasised what i had done (or at least what i think i have done). would i be right in thinking that the battery now does not have enough power to boot android and get to a point where it can charge the battery?
having seen the threads on here about using a USB lead to manually charge the battery i am at my wits end. i tried the USB fix and it didnt work.
i have now found this thread: http://forum.xda-developers.com/showthread.php?t=978101
and am currently attempting to charge my phone using the "USB mass storage" setting on MAGLDR (v1.13 btw) but the bit that im wondering is the bit that says "you will NOT get a charging indicator in this mode"
does any one know for sure whether this is true? i am hoping that the thread is correct my only doubt has arisen due to the fact that the thread was based on a HD2 running WP7.
thanks in advance for any help

Try to measure voltage at pin +/- on battery. If there is more than 3,6V battery is able to boot up the phone if voltage is belov 3V it's bad. If You have an adjustable (for laboratory use) voltage source, connect it to pins of phone vhere normally must be connected +/- leads of battery (carefully check polarity), give it 3,7V and try to load the bootloaderon the phone (hold Vol.Down butt and power button together). If it doesn't work, you may have ruined the bootloader.

I read some of the thread you linked. There is something that I think the OP of that thread and a whole lot of people using MAGLDR do not understand. I qoute this straight from the OP of the MAGLDR thread.
*Fixed Power-Off-Cable-Plug-Stop. Phone now detects this situation and reboots. Battery controller inside LEO needs runtime control during charge, it implemented in OS.

You have to have a functional OS installed for you to even be able to charge your battery using your HD2 when you have MAGLDR installed on your HD2. The simple fact that the OP of that thred has a WP7 ROM installed on their HD2 is the only reason option #4 USB Mass Stg even will slightly charge the battery, if it was no ROM on the phone, just MAGLDR, it will not charge at all just as when you are in bootloader and the USB connected it will not charge no matter if you have a ROM on the phone or not. I personally think the slight charge you get by using option #4 USB Mass Stg in MAGLDR is purely accidental and only a small amount of voltage as it takes so long to get any kind of substantial charge. Also if you have a completly dead battery you can not even boot into MAGLDR to try to charge using opyion #4 of MAGLDR.
I am a electrician and have been for a little over 15 years and in my oppinion if you have a dead battery and you are running Android from NAND or a WP7 ROM using MAGLDR. Your best bet is to use.
A: A external charging cradle.
B: Another HD2 that is running Win Mo.
C: Using a modified USN cable to get enough charge to boot into your ROM
Note: The last option I listed is only in a emergency situation as I do not advice you use this as a everyday charging technic. Also only long enough to boot your phone so you can finish charging normally. If you do use this option maintain a constant watch of the battery to insure it does not start to become warm, and only use your wall charger when using this method. The voltage is very low that the wall charger sends though the witres so there is no danger of shock.

Do You mean that when HD2 is POWER OFF state it doesn't charge battery? Even from wall charger? Mine does charging pretty well when turned OFF...
All phones I repaired or dizassembled had hardware automatic for charging battery, not depending of ROM or OS at all, it must have only 5V at charger inlet (USB or dedicated charger port i.e. for NOKIA), I doubt if HTC gone other way that all other developers

Yes a HD2 can charge in a powered off state if you are still running a Windows Mobile ROM on it. If you have flashed MAGLDR to your HD2 you will not be able to charge your HD2 until you flash a Android or WP7 ROM to it as the charging is to quote the OP of the MAGLDR thread again, "Battery controller inside LEO needs runtime control during charge, it implemented in OS."
As for as a schematic no real need for a schematic. You take and cut the end off of a USB cable, the end you leave on needs to bt a standard USB male end. Next you strip back the outer insulation and the inner foil layer, then strip a little off the ends of the black and red wires. Finally connect the red wire to the positive terminal of the battery (marked on the battery), and connect the black wire to the negative terminal on the battery (marked on battery) and plug the USB male end of the cable into your wall charger, not any other power source. Yopui can use some tape to keep the ends connected to the battery.

You tried this even one time???
NEVER DO THAT, YOU WILL RUIN YOUR Li-ION BATTERY!!!!
Li-ION charges at no more that 4,2V, internal protection circuit will shut it off if you get it to 5V charger directly and if this protection accidentally will not work your battery blows up! 5V must be applied to USB port ONLY if you want your battery and phone alive

unfortunately i dont have a way of measuring the voltage of the battery, i have now just bitten the bullet and ordered another battery and an external charger. that way if the battery i have now is dead i have a replacment and if it just needs charging then ill have two batteries. having tried the USB cable charging bodge and it not work im thinking i have killed the battery. i use LiPo batteries in my airsoft stuff so i know that they can die if not treated properly. my own silly fault i guess haha.
ill update tomorrow once the charger and battery have arrived.
what do you guys think will be wrong with it if a new full charged battery doesnt work?

If your new battery wont work than you probably may have a dead charging circuitry on your mainboard (sudden death when removing a battery during charging process) and if that circuit works only under OS control, IMHO your mainboard is useless too. Have to be replaced or repaired.

fair enough, thanks mate. fingers crossed for tomorrow the hehe

I have not personally tried charging a my battery this way bit I know several people on her that have and it does charge the battery. If it did not work for the OP of this thread than they either did not have a good connection between the wires or the battery is not chargeable anymore.
Look at your wall charger it should say on your wall charger that the output is 5.0 v or 5.1 v. This is pretty much a standard on all wall chargers for phones as they all require the same voltage. Yes there is a protection system that monitors the charging voltage and if you use the modified cable to charge you do not have this protection system. But your wall charger unless the small transformer in the actual plug part that is the charger malfunctions will only put out 5v, actually it will probably be more like 3.5v as the 5v is Max output capacity. Also if the transformer malfunctions it is just going to melt down and not put out a charge what so ever, it will not cause a spike in voltage. Trust me on this one, my job requers I have a full understanding of transformers be it a big one are a little one as I have to work with them all of the time. But I did put my warning in there for a reason as this can kill the battery where it can no longer charge, and even though it is menamal it is a small risk of the battery exploding, but it is a very small risk.

Just for info I've done this twice, once thru wall once thru usb slot. It only needs about 45 seconds to get enough charge to start booting, and charging starts about halfway through the boot.
you are right that it isn't recommended, of course, but then most of what goes on on this site isn't recommended for a healthy phone

Man, I do not intend to start a holy-war about it
It's a little off-topic, but seems that you do not have idea how these power stage of mobile devises works (from wall outlet to battery), all mobile devices are very similar in this aspect, simply google what is Li-Ion battery advisor, how it works and rules of charging Li-ion batteries, there are a huge bunch of forums specially dedicated to this theme...

Ok first of I am not madd by no means, and no it is not off topic as people need to be able to know these things. As I have seen in a couple of XDA members signatures "I am learning from you, and you are learning from me."
I Googled the Li-Ion battery advisor and found the PDF I think you were talking about as it was the first two links Google pulled up. But I have to tell you what is discussed in that PDF is on Li-ion batteries for vehicles not cell phones. Those batteries are much large and there for data in that PDF can not necessarily by applied to cell phone LI-ion batteries, unless you care to educate me further.
Like I said I have been a electrician for going on 15 years now, I know how to read electrical schematics, I know how electricity flows, I know about positive and negative charges, I know a lot I will just put it that way. If you have further links YOU would like me to check out I will be glad to. But from my prospective what I mentioned as a emergency charging method is no more dangerous than shaving with a disposable razor.

right so the new battery doesnt work, charged it in the external charger and nothing. same as before just looping on the Droid boot up screen.
would it be worth flashing back to WM6.5 as a last resort?

Any photos of boot screen?
Try to flash back to older official WM ROM with regular SPL (flash from SD card not thru PC sink), else HSPL and that custom bot manager wont be erased from NAND. May be it will help You, I used this method when my touch stopped responding and it was a solution for me.

You are correct to tell the OP to flash via SD card or they would still have HSPL. but the custum boot manager as you called it is actually a custom bootloader. And if you flash a Windows Mobile ROM be it custom or official through RUU or SD card it is gone. MAGLDR or cLK bootloader run in sesession of the original bootloader meanning you never lose the original boot loader( if you did you would have a bricked phone) and that it is not in the same partition of the NAND memory as the original bootloader. MAGLDR, CLK, AND CWM are in the same partition as the OS, therefore when you flash back to a Win Mo ROM you lose them.
HSPL would not have anything to do with the OP's problem as it is part of the original bootloader and the two main purposes for HSPL is to one beablecto flash a official ROM that is not meant for your HD2 without having to use a gold card, and to disable the CID check so you can flash custom firmware.
At the OP have you had a look at your battery pins to make sure they are all in properly aligned with each other and that one is not bent?

HD2 Doesnt charge battery,help needed! (not usb,battery fault)

Hi Guys!
I have a problem with my Htc HD2, it doesnt charge! I installed windows phone 7 nand rom to my hd2, so the connection was made and usb cable is charging, have tried it with stock Htc Wildfire. The battery is ok, because i have a battery charger and the battery is charging.
Used Magldr v1.13.
Any help would be appreciated, btw have read several topics,but no solution has found.

I don't see a problem here.
You said it doesn't charge and then you said it charges.
And the battery charges from external battery charger too.
Where is the problem?
Edit:
lol, after reading again and again I finally found your problem. But using correct grammar and correct punctuation would've made this a lot easier
Make sure that the battery pins on your phone are ok, also check the usb socket on your phone and make sure it's not faulty or malfunctioning

reading comprehension ftw.
Anyway, I had a similar problem and I found that it was the pins connecting directly to the battery, the three little ones you see when you pull the battery. Make sure there aren't bent down and smashed too much. You can still get the battery to supply power, but it wont take a charge. Anyway, hope this helps.

I had the same problem, HD2 didn't charge, the orange LED just flashed and battclock reported a temperature of 250°C. Problem was the middle battery connector, it was bent behind the battery and so it had no contact. Remove battery, try to carefully get these three connectors in correct position and try again.

Thank you so much!!!!! I thought my phone was dead then I checked this. You are my hero!!!!

I had the same problem and it was driving me crazy. I tried putting the stock ROM back on, WinMo 7, charging with the computer and USB and nothing worked, I still got the red/green blinking LED and the battery died. I bent the middle pin back to normal and now everything is working as usual.

It works for me
thanks ... joshwake
nice ICS on hd2

[Q] HD2 Won't charge

I've just been on holiday with my HD2 and after a day on the beach it now won't charge. I'm assuming that the connector is duff, however at 18months old I'm guessing it'll be out of warranty. It is insured, but since I've installed Android on it, that will have removed any protection I have for it. Does anyone have any advice at all, or is it time I said goodbye to it?

did you use magldr?
Magldr prevents the phone from charging unless it is on and booted into android.
You can
1 - use another hd2 running winmo to charge your battery
2 - get an external charger
3 - borrow a charged battery, use it to flash winmo to your phone and use your phone to charge your battery
4 - get a mini or micro USB cable (can prob do it with the larger printer type usb cables too, whatever you have about), , , cut end off, , , bare the red and black wires, , , plug into wall charger and apply red to + and black to - for about a minute, maybe two, , , battery back in phone, hit power on, plug real USb cable into phone and wall charger, , hope that you gave it enough juice to get half way thru booting, which is when charging will start. If you didnt. and it dioes , , try again for longer.
U can use your fingers to hold the wires, it wont shock you.

Also if you are in the EU its a 2 year warranty, all you need is to borrow a charged battery and return the phone to stock, same for insurance of course

my hd2 is not responding and dead after flashing it with under 50% battery, help

i bought it from hours , and i forgot to charge the battery and make it full
got some errors while flashing and hacking it after that i tried to restart by
removing the batt and put it again but Unfortunately it never opened again it's
dead now even with charger or the usb cable ...
any help please?

Sorry bit if your battery died while you were flashing, it is very possible that you hard bricked your device. Please post back with what percent it was on when it died. Maybe XDA Senior Member Samsamuel can give you a better clue if you post this info.
Anyway if it is hard bricked you will have to have it JTAGed or ha e the main board replaced.

i think it was 40% i guess .. i don't care much about the battery , I WANNA USE THE PHONE

Flashing usually only uses 2-3%, I've flashed with less than 10% charge loads of times.
More importantly would be what rom did you flash?
Tmous or regular hd2?
Have you checked the battery pins very carefully?

no it's regular HD2 , i was partitioning CLK ..
if it's not that important , what else could cause this problem ?
about the pins no i didn't

Please any help ?

Buy an external battery charger, the ones you charge off mains. Charge your battery off that and then see if the device turns on?

... or, if you have a spare USB lead, any type, cut end off, bare red and black,hold red to + and black to - on battery, plug into wall charger and hold onto the terminals for about a mninute which should give it enough power to turn on, and if it does turn on get the real cable plugged in quick.
