Let Andriod die now have a paper wheight

ok here is the problem.
4 nights ago i forgot to plug in my hd2 while android was running and the battery died.
the next morning i went to turn it on and the screen no longer turns on but the phone does boot. the battery doesnt charge, status light doesnt either, end key doesnt work, when i answer calls no noise can be heard or made.
any hope?

Im guessing you cant run bootloader?
Maybe this is a warrenty jobby

If you know someone with another HD2, Try swapping the battery.

Hi Chris,
Please eleborate/clarify your OP, because I don't think anyone gets this... At least i don't! You say the screen doesn't turn on but the phone boots?! How do you figure that? Your device is actually on because you can receive/answer calls!?! :S
Sounds like your device has just BSOD (Black Screen of Death) which is discussed quite a lot here. Just press reset button or pull the battery (please tell me you have tried that before...).
If your device IS NOT powered on, please try this:
Does the device vibrate shortly when pressing the End-button? If so you should leave it connected to the charger for longer. If battery has drained too much it takes a while for the device to allow it to power itself up (prevention of overdrainage, which Lithium-batteries don't like very much).
Do you charge through USB, or with the supplied charger? I've had this before trying to charge it with a (different brand) microUSB charger. Turned out most chargers only give out 500mAh, whilst my normal charger (and car-charger) give out 1000mAh i believe. That might help.
You can order a cheap replacement battery from China (i got mine with dockingstation), which is already charged about 60% (for storage purposes).
BTW if your problem is fixed, please add the prefix [FIXED] or [SOLVED] to your topics title.

i have restarted many times.
i use the wall charger.
but why would the phone boot but not turn on the screen or have the mic work?

remove your sd card and the battery. you may have to hit the rest button on the back after you plug the battery back in as well, but as long as you have the sd card out it should come back on. try plugging the phone into a charger and then remove the battery as well sometimes it'll wake it up so to speak. it's just a matter of playing with it. mine did the exact same thing and i freaked out for a little bit.
now if after all this it doesn't work and you've played with it for a while then yeah, best of luck to you =\. but whatever you do in playing with the battery and the charger, keep the sd card out until you can boot into winmo.
EDIT: never mind, i thought the phone wasn't booting. i misunderstood, but i went back and reread the original post. try reflashing your rom if you're in winmo and experiencing those issues. or take the sd card out and reboot.

i would suggest making an backup, as your phone turns on you should be able to estaplish a remote-connection with some (3rd-party-)software and do a hardreset.
if this wont work i would recommend setting it back to factory default (revert hspl if you have one and install stock rom) and send it in for warranty.
seems to be some major problem...
All this steps should be possible without screen turning on (working touchscreen may be needed for backup, but flashing doent need screen input)
if drive-mode is default for your usb connection and holding you from flashing you can do a hardreset and afterwards active sync will be default again and you can establish an active sync connection and flash

check if any of the pins that contact the battery are bended or broken, try to avoid removing the battery when you have to reset your hd2 because the pins are fragile

similar thing happened to me just last night!
I tried the jmz dual boot last night and I was nearly out of battery. I didnt look at any instructions I just installed it and restarted the phone to check out the new toy. it finally got done loading I chose android right away and I was walking towards the bedroom. when I went to see if android had fully booted and plug in the phone I had nothing! It was off. I decided that the battery must have died so I tried to turn it on and all that happened was the tmobile flash screen came up for a second and then it went right off, I got so desperate that I was going to do a hard reset but that wouldnt even work! the boot loader screen would just shut right off. I was suggested to try another battery we had at the house and bang it fired right up I took a wiff of my other battery and I dont know what happened but I think I let the magic smoke out cuz it is fried!

hello friend...i have a problem similar to this. basically when my phone is in android which i use alot if it dies in android, when i reboot it it will turn on for about a second to see my splash screen then turn itself off (the battery is obviously flat). so i plug my charger in and it stays on now but doesnt indicate charging....i boot it into windows mobile and the batt just stays at 0% but its still working. however once i unplug it it will die.....its like the battery is not in the phone. luckily i have two batteries and a dock which charges batteries, so i replaced the battery and everything works fine. once the battery that died in android was fully charged i tried it again and it was fine.................im guesing the moral to this story is dont let your phone die in android mode

I do notice my HD2 runs hotter while in android than while it runs in Windows.
I am not sure if that's an issue to this, which is why I never mentioned about it being hotter. Although my HD2 is noticeable hotter, it never gets to a point that I think I should unplug the USB due to overheating concern...
Just a few inputs from passed experience
I use TMOUS Stock 2.13.531.1 WWE ROM
2.12.50.2_2 radio (not stock)

k going to tmobile today to see if they have any extra batteries i can try.
then ill update

i went to tmobile. and while i was there i noticed the screen was turning on but very dim without backlight (barely noticable). but the rep helping me did not notice and i let it stay that way because tmobile is sending me a new refurbished phone as long as i send the old one (and the rep was totally cool he uses xda also and said they wont check my software and if they do they wont ask for the phone back). he also let me get insurance in case this happens again, instead i will just say its lost. so i basically killed 2 birds with one stone

[Q] Dead Battery Issue

So I thought I had turned my phone off last night because I left the charger at work but apparently it did not shut down and the battery died. I know that MAGLDR doesn't allow charging while the phone is off, does anyone know a way to get enough of a charge to get the phone to turn on so I can charge it fully?

I can charge in MAGLDR, just the orange light sticks on and will stay on until you pull the battery. Try giving it a few minutes just to get some charge in it, pull the battery, turn on and start the booting process, then plug the charger back in, works for me on NAND builds, did it last night even whilst calibrating my battery.

Ok I will plug it in and leave it for a bit, the orange light shuts off after a few seconds but we will see what happens. I was always under the impression that MAGLDR didn't charge

That's correct, magldr won't charge.
Another solution I saw a few days back said to go into Bootloader and charge from there - just tried it as an experiment and unless it charges without activating the charging light, Bootloader doesn't charge either.
When I had a similar problem I just kept booting it up into WP7, allowing it to charge for a few minutes until WP7 shut itself down again and then pulling the battery to repeat.
It took 5-10 cycles of this but eventually the phone decided it had enough battery to charge itself - seems daft to me too, but there you go.
If all else fails, search this forum - there was thread from a week or so ago where someone chopped a USB cable to charge directly to the battery terminals. A spare battery is also an option if it fits your wallet and timescales.

[Q] HD2 dead Battery?

I woke up this morning and my phone was off. As you probably already know, the HD2 does not stay off if it is plugged in (with WP7 on it). I checked the charger and outlet; everything was plugged in. I also used a different charger, and different outlet which I know works, and got the same result. When the phone was plugged in it would turn on and start booting then I would see the flashing light - indicating that the battery was dying- and the phone would shut off. This happened like ten times.
I took out the battery and put it back in, with no results. Then I switched batteries and it finally worked. I'm still learning about technology in general; is it possible that my other battery is dead?
Has anyone else had this issue?

your other battery is probably just flat, and cant charge because it needs a running OS, and since the OS cant get far enough into the boot sequence to start charging, the several times it bootlooped will have drained the last of the charge.
Options - external charger, loan of a hd2 running winmo, or my personal fave, (used it three times now) usb cable with end cut off, red wire to + black wire to - on battery, hold for a minute or two, should have enough juice to boot far enough to begin charging. Best to use wall charger rather than pc usb, since the pc may connect and disconnect time or two whilst booting, preventing continual charge.

I forgot to mention that the first time that the I booted with the battery that doesn't seem to work I actually got to the wp7 home screen and it was about 20 seconds before the phone died.
Even so, I'll try that cut off cord thing when I reach home. Thanks for the advice.

I guess my phone just felt like being retarded the "flat" battery is working now.

[Q] Cant boot. Battery wont charge?

hey guys.
charged battery at night used it at work all day came home around 10 and battery was on 1%..went upstairs to charge but phone but was dead. when plugged into wall phone boots for 2 sec then turns off and boots again for 2sec....constantly looping like this? im pretty sure i just need enough charge so that i can boot into android and ill be sweet. but doesn't even get half way there!?
need help. cant charge.
im leaving the battery out for the night and im gonna try again tomorrow but any suggestions would be great!
thanks

Not sure but you can try this: hold down power button till mgldr menu comes. Stay in mgldr menu for some time and get some charge,then reboot.

Phone will not charge on magldr screen. Android needs to be booted to charge.
Get old USB cable, mini or micro, cut end off, bare red and black, take battery, connect red to + and black to - ,plug into wall charger and hold wires on battery for a minute or so, reinsert battery, should be charged enough to get far enough into booting to start charging.

First.. i had the same problem.
it have to charge while off.
before you cut off things, check the batterypins. one of them was broken on my HD2 (i saw one of them below my battery).
if so, try to hold that broken pin back while insert the battery and try again.
you could also buy a dockingstation (something like that: http://www.amazon.com/Fosmon®-Premi...P2YS/ref=sr_1_4?ie=UTF8&qid=1313518480&sr=8-4) to charge batterys.

I had the same problem once, I`m not 100% sure how i solved it but I think that I pluged it in that it started booting and removed then the battery. I think it doesnt start automatically if you reinsert the battery then... but I´m not sure about it...

thats correct, but relies on the bootloader being able to charge when off, so this method of fixing the discharged battery problem only works with winmo or cLK

Your right i had that Problem in the time i was running it with winmob andere haret

Charge while in bootloader or hard reset screen, it should charge from there.
However, the charging process using the aforementioned methods is kind of slow.

hey guys. thanks for your responses. i have left it overnight and it doesnt get to the 1234 bit. i have 3-4 cords so i cut one up however it has blue, red, white and green cords....whats positive and whats negative?
also my pins are fine.
this is killing me!

Thank you to samsamuel, i ended up cutting my old cable. connected the red cable to + and the white cable to - and left it for a hour. just booted my phone back up and got 1000 msgs and emails lol and im on 84% battery.
thanks again to everyone how posted!
much appreciated!

Good to hear,, for anyone else thinking of trying it, an hour is pushing it a bit, you are running the risk of damaging the battery since the charge control circuits aren't being used.

What Android build is this? I remember having a build once that required a special key combination to charge the phone up. I think it required you to hold the volume down and power while plugged in to the charger and it could charge from there. I don't remember exactly though.

Nothing to do with the build,,, if you have magldr installed the phone must be on and booted into android to charge.

EDIT: I realize now that it must have been something else, can't charge in HSPL or MAGLDR (duh). I have no recollection of what though (if anybody knows, let me know because it's driving me nuts now!)
OP, you do also realize that instead of cutting up wires you could get an external charger for your battery and just charge the battery alone, right? If you've wanted to buy one of those fancy desk docks you could get one that also charges a battery behind the phone

[Q] Charging While In MAGLDR 1.13

Ok, so last week my iPhone got lost, and I had to get a new sim card (on AT&T). I asked all my friends if they had any sim card phones I can borrow, and one of them let me use her HTC HD2 (T-Mobile branded).
I installed everything correctly, Radio, MAGLDR, HardSPL and Android perfectly. The phone has been working great (sans 3G) for the past week.
I noticed the battery died VERY quickly, and seeing as the phone was old, ordered a new one.
I got it in the mail today, and upon plugging it in (because of MAGLDR 1.13), it automatically turns on and tries to boot android from NAND.
Here is the problem: It doesnt have enough battery to fully boot up, so about 5 seconds after showing the Dark Force Team screen, it reboots. And loops.
I can find no way of charging the battery. Wall chargers and USB cords do the same, it automatically turns on, and will NOT charge.
I'm not sure why MAGLDR automatically turns on the phone instead of just keeping it off, or am I missing a setting somewhere?

Pull the battery press and hold the power button until it boots into magldr and leave it like that for 10 or 15 minutes it will charge but not indicate its charging then switch on normaly

It continually surprises me that the advice to "boot into magldr and leave it for 10/15 minutes" keeps being offered.
the person who wrote magldr clearly states that the phone WILL NOT CHARGE under magldr,,, android must be running. The code to control charging doesn't exist in magldr, it is not possible to charge using only magldr. That's why magldr starts the phone when it detects the USB connection,,,, so that android can boot to allow charging to start.
OP, get a spare USB cable, mini / micro, cut end off, bare red and black, take out battery plug usb into wall charger and hold red to + and black to - for a minute or two. Should now be enough charge to boot into android and start charging.
When a battery is empty, but only just empty, not fully discharged, letting it rest for ten mins often allows the residual charge to build up a little, so a phone that wouldn't start suddenly has enough to just about start. I believe this is why people think leaving it in magldr charges it. It doesn't.

I left it for an hour and still the bootloop.
I even tried it with the battery I know works. After 25 minutes the battery had 3% less charge then before I left it plugged in at the MAGLDR main menu.

if it bootloops with a good battery, there's a good chance it is a bent battery pin. Either that, or sometimes when a battery dies whilst the OS is running, it screws up and then wont boot until you do a hard reset or fresh flash. (However normally it would hang rather than bootloop, but anything is possible)

Are you sure about this? Because if you turn off phone at 1% charge, turn on MAGLDR 1.13 -> USB FLASHER and leave it over night, battery is at 100% when turn on and lasts for a day.

Just going on what cotulla says, and since he wrote magldr he knows that the code to control the charge circuits doesn't exist in magldr, plus the OP says he left it in magldr and the % went down.
However you sound like you've tested this yourself, so I shan't argue with you, since I haven't.
Perhaps USB flasher mode exposes the battery terminals to raw USB power, bypassing the charge control circuits, giving the same effect as holding bare wires to the battery?

Yeah I'll have to figure something out. And not to knock the writer of MAGLDR, because I could certainly not create something like it, but I find it odd and almost disturbing that the creator is fully aware that a dead battery basically bricks your phone?

I think "bricks your phone" is a bit harsh,, its not like its a surprise, most roms spend the last 15/20% warning you of low battery.
I've used the bare wire method three or four times now when my battery ran out, and although I did say it sometimes won't boot after running out, as often as not it does boot ok. I'd go into cwm and clear cache,, if that doesn't help I'd try a cwm backup,hard reset (via cwm, not the built in bootloader hard reset) see if it starts fresh, and if it does restore SD ext,, if THAT works I'd then restore data.

Just a quick related question - can you charge your phone while in bootloader? I couldn't find an answer to that but I need to know...

Allegedly not. At least that's always been the answer that has been given for the past two years. I for one believe that it doesn't charge in bootloader.

Heres the update : I had a bad charger and the usb cable was messed up as well hence the phone dies on me as battery got over. When i was trying to charge it, was getting a bootloop because of MAGldr so what i did was left the phone in the main Mag menu for 5 mins and rebooted and viola it booted in android and is charging now hope this helps i guess somehow MAG does charge your phone cheers
