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] After several cycles on WP7 HD2 won't charge

After several cycles on WP7 the batt was fully drained and now it won't charge (charge LED goes on for few seconds and then goes off). It won't load either, just switches off on DFT screen. Batt is standard.
Guess it is critical not to allow batt to drain fully on WP7?
Is there any solution to this?
Thanks for any ideas.

Had a similar problem with Android...battery drained completely and wouldn't charge. I solved it by cutting the end off of a spare USB cable, removing the battery, and charging directly from the cable (red wire to positive/black to negative). After about twenty minutes I put the battery back in the phone and it booted Right up. Or, if you have more sense than me, you could just pick up an external battery charger...I'm just the hack apart a cable and do it caveman kinda Guy...

I can confirm a similar experience; I thought it was worth trying the fully-drain-then-fully-recharge regime suggested elsewhere on these forums as a means of extending battery life, which does struggle a bit on WP7.
The fully discharge bit was easy, but it is worth everyone bearing in mind that magldr - as advised, I believe - will not allow the phone to charge. As a result, I was getting into WP7 (just) only for it to almost immediately shut down. But it was at least doing a small amount of charging before it did.
After a sweaty fifteen minutes or so of restarts (I was having to take the battery out to force the restart as it wouldn't start on the power button), it decided it had enough charge to...well, charge and all was well.
My suggestion would be not to risk going beyond the critical warning WP7 gives, at least until magldr is able to offer charging.

Almost the same issue here, without having let the battery fully drained...
I can't charge my hd2 anymore.....if it's turned off.
But, it Can be charged if wp7 is running! I don't know why...
I had This issue when I received the phone. It took me a whole Day to charge the battery the first time : orange LED turning off after 10seconds (HD2 switched off or in wm6.5
Once the led is off, can't turn the phone on or charge it again until I remove and put the battery back.
It was in summer so I thought the phone was too hot, so I cooled the battery with a fan, replaced it, retryed... At least 10times, and it finally charged.
SO weird, I'll test This again with wp7, who knows?

I am wondering whether it is some kind of magldr bug?
I'll try the trick with the cable directly to the batt. It is not very practical though if you drain your batt, where there is no access to spare cabling.

This should be put into the sticky rollup thread for people who have let their batteries drain.
Why dont you do some pics bud and create a topic?

I am cutting the cable as I write. Will take some pics.

If your battery drains completely, just remove it, replace it back. Without starting the phone, connect it to your PC. start and enter the bootloader. You'll be then able to charge. I did it like that last week.

Running cable directly to the batt is confirmed to work. Just revived mine with this trick.

Less of a bug and more of an unwanted side-effect of having this excellent capability, I think. I seem to recall that the developers are aware and looking to see what can be done.

I guess it is possible to completely drain the battery, in which case this won't work. But if there is some power, removing the battery and replacing it should kick the phone into life for long enough to do this. This was going to be my first try if persistent rebooting hadn't eventually worked.

having this problem and definitely charging below the amount...
i cant fully charge the battery as well

Like I said, if connected, but not started, to your computer, you'll have enuff time to start it then and entering the bootloader, of course, you gotta be quick for this to work.
If it doesn't respond, don't laugh, confirmed to work, remove your battery like explained and put it for some mins in the fridge before replacing it (it's only chemistry playing here, somehow better than cutting a USB cable in 2).

"storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. "
I suggest you to be more polite when answering and learn your lessons before posting!

I finally made a dual boot Android/WP7.
At first, Android said my battery was fully charged, just like WP7, which is totally impossible as I used MAGLDR to format the SD card (wp7 & android partitions) and that it took me almost 1hour, without any possible way to charge the battery while I'm in bootloader mode.
But when I turned the phone off, plugged into the wall.......TADAA It was finally charging, with phone turned off
So, it seems that dual boot may be a way to solve this issue

You're arguing against yourself here aren't you? Cold may be fine for storage but you need heat to coax a little more power out. You even say 'you need to wait until they've warmed up before using them'.

Wrong idea, sorry guys.
I thought that HD2 was charging since I installed WP7 and Android in Dual Boot. But it's a fake : if the phone is turned off, and that I plug it, the orange led turns on. But that's all, even if I unplug the phone, the led remains turned on !!
And now, Android as well as WP7 are telling me that the battery is fully charged but I'm sure it's not even 50% full.

Bricked

Need some help hope i post this in the right place. i have gingerbread on my HTC HD2 and was converting back to windows to sell on ebay and i started it was almost done when i relised before i started i forgot to charge the battery and it ran out before it was done know the phone what turn on at all. i plug it in the wall charger nothing, plug it into the computer nothing tried everything nothing. do you think that the battery is that dead and it was in the proccess that the chargers dont work on it no more. would it work maybe if i had a charged battery to put in it. it mite come back on. any help would be great thanks.

Just keep it plugged in for 1-2 hours and then try booting in to try color screen bootloader and go from there.....

If you have MAGLDR installed then you can not charge the battery when the phone is off.
You should try to charge the battery using an external charger.
Edit: If you have a friend with HD2 and windows Mobile 6.5 then you could use the phone to charge you battery.

Wrong, you can charge it while it's off.

really? are you sure? because there are a lot of references to the magldr bug that wont allow charging (or even powering on without pulling the battery) if you try to charge with the phone turned off.

well i tried to charge for the last 2 hours nothing tried to remove battery nothing. Iam going to try and find a charged battery to see if the phone mite turn on or something. ill post later to let yall know what happen tho. thanks for the help.

Just give it a try man and see for yourself whether it charges or not....

what are you guys fighting about man, they just updated the magldr v1.3 and yeah we can now charge the phone while its off

Wrong x2.
1. No one is fighting.
2. With new magldr, phone turns itself on when plugged in. Charging when off is not possible. The battery requires management which is only implemented in software. It may hold a small charge if you have magldr installed, but it won't charge fully, or properly. Also, it's not likely he's got the new magldr if he's returning back to windows.
Lastly, for the OP, what method did you use to return to winmo? And which winmo rom did you use?

Read? Phone turns itself on if you connect a charger. Phone has NEVER charged while off with nand. This way at least you don't have to pull the battery to turn the phone on.

Just in case: If you on same situation that described on first post try this:
Q: If you completely run down the battery, would you be able to charge it with the phone again?
A: If your battery is dead, press and hold Vol Down and plug in USB cable / charger at same time. Phone will boot into bootloader and charge there just fine. Leave for 20 mins, pull battery, reboot and charge normally. If phone has just run down, plugging in the charger will usually turn it on.
Its found on one NAND thread and goals goes to g.lewarne
Actually i was on same situation and this helped on first try.

check the connection between battery and phone , the metal things i mean.

Perhaps, it is off the subject, but...
Poster #1: why do you want to get rid of this beautiful phone?
Just curious...

ok i bought another phone and i took out the charged battery from it and put it in the bricked HTC and it does nothing. now i know it was almost reverted back and i think the battery ran down but Iam not completely sure but maybe it could have been in the reverting software i used and maybe it just like lock up or something cause at that point you couldnt see the battery indicator. now i guess ill just have to sell on ebay for parts but it would be cool to try and un-brick it or try and figure it out.

HD2 very expencive brick????

Last night I playing games on my Leo(MIUI Rom (Lady last 1.6.10 MAGLD android)),and phone was freezed(no respons on any buton).I pull out batery and gona to restart it,but i cant to turn it on.Left it on charger all night but I cant to turn on,cant to turn it on eather in tricolor,its death.
I use to have this Rom about few days so I thing thats is not question of rom.
What to do ,go to HTC i still have a waranty but the phone is flashed?

When you click power button to try switching it on, nothing happens? No vibration, nothing on screen?
Do you have someone with HD2 to try second battery? Maybe it is not bricked but only battery died.

Well to be honest Icdo not think your HD2 is bricked, it sort of sounds like you may have a dead battery. With MAGLDR you can only charge your HD2 while you have the ROM you are using booted up and running. Also try this just in case your battery os not dead but your power button is malfunctioning. Take the back cover off and press the small reset button on the back, it will be red, yellow, or green. Also make sure to have your charger connected to your HD2 in case the battery is low, it will start charging about half way through the boot up process. I will check back in on thos thread later today.

follow T-Macgnolia advice, if you can find another battery just to try if phone does boot up... after making sure that its not a battery problem ( i hope it does ) than could be that your phone is bricked and for now only jtag method could fix it.

I've never, ever heard about a really bricked HD2 unless a faulty hardware... In you case it might be the battery or a hardware issue.
HD2 is almost impossible to brick.

Unless you flash the wrong radio, that's basically it.
OP, make sure none of your pins bent when you did your battery pull. Sometimes one of the pins gets bent and it won't turn on, you have to make sure all 3 pins are touching the battery.

I think the answer to his question is between the lines :

Since Android doesn't/never brick devices and he hasn't flashed anything and his battery was working fine, Simply it's a bent pin
orangekid is correct.

Thanks for yours answers friends.
Pins are Ok.
I try to hard reset but nothing.
So when baterry is empty i cant charge it with MAGLDR i didnt know that.
Maybe is only batery empty.
I dont know no one with HD2 .
Is the same batery with Desire HD ?
Can i mesure voltage on batery i have multimetar at home.
Im having wall charger for my bluetooth headset with LED when charging its light RED,so i put HD2 withaout batery its green(no charging) and put batery in HD2 its light RED(charging).
P.S: Sorry for all this questions but im use to conect to net over HD2,
now im on dialup and this is very slow way for surfing and googling around.

Ok, So the phone is turned off. When you plug it in, don't you see the orange light even for 1 second?
Also, was the phone really hot when it freezed?

No there is no orange led turn on,phone is cold,i even try to charge batery direcly,voltage on batery is 3.75V.

Head down to your nearest T-Mobile store, most likely they have a battery or two you can test it with. If that ends up being the case, theres also chargers you can get pretty cheap that charge batteries stand-alone, along with a spot for a usb cord to charge a battery and phone at once. Got mine off ebay for 4$

Yeah, I can't see how you can brick your device without actually flashing something.
I, on the other hand, flashed a bunch of things like an idiot and I think I really may have bricked my poor HD2. It gets no power, and I've tried a second battery and that doesn't work either although it does turn on with external power.
Here's a link to my thread if anyone has any insight for me.

I meant the moment it froze, was the phone hot?

Ye the phone was hot i played drag racing on line with wi fi conected when it froze.
Sent from my GT540 using XDA App

If it was really hot, then it could be a hardware failure.

Mine also got hot while running gps and now appears to be dead, have tried another battery but get no lights when pluggin in, no bent pins, is it the motherboard are they cheap/easy to fix?

Thanks, i thought i briked my phone , i leaft it to charge this night and when i wake up it won't turn on, i was very scared until i read here that could be a battery pin problem so i saw that i had the middlle pin to high, just lowered i little the pin and the phone booted up, thanks a lot.
But now i'm worried because here i read that if the phone get's to hot has changes that it will brick, what would be the best solution to not brick the phone: downclock or just pray and don't use android at full capacity?
Sorry for my english but i'm better at reading then writing

Bricking caused by HD2 beeing too hot ??? I doubt it...
Nevertheless it is not adviced to always overclock at full speed...

Bricking from an overheat is quite common, I've seen a good number come through my store with that issue.
For some reason alot people think the dashboard is a great place for their phone while driving around Phoenix o.0

I'll throw this suggestion out there. Most likely it's not the problem, but maybe you can try charging your phone in a different outlet.

HD2 dead !!

Hey folks, i have a HD2 which isn't turning on. I received a call and it just switched off. Now there is no activity in it at all. No led when connected to a charger. I had MIUI installed on the phone.
The repair people say that the motherboard needs to be replaced which would cost approx 12000INR.
Any way i could revive it back?
Please suggest. Thank you!

You can try the the freezer trick, put the device in a zip lock bag and put it in the freezer for a few minutes and then see if you can turn it on or charge it. You can also take a old USB cable and cut the mico USB end off and strip the wires back then touch the read to the + on the battery and the black to the - on the battery for a minute or two and then try to boot the device. I sorta souds like you were using MAGLDR and the battery died. You can not charge the device while it is off with MAGLDR. So I would try charging the battery first.

Thank you for replying. You're right i was using Magdlr. I'll try what you said
Sent from my ST25i using Tapatalk 2

I've got the exact sam prob, the HD2 was using MAGLDR, and now it won't start (except for a few times it did), but I honestly can't figure how - since once it had been charged on an external batery charger, and then it turned on and worked for a while, but now it won't work with a charged battery...because I tried using it with another HD2 phone's battery which also has MAGLDR and which works (even with my phone's battery).
The pins have been changed, and it worked then also for a while I've been said, but it's not working again now.
Any help please?
TIA
P.S. I've tried ziplock...15min...nothing :/ How to try the USB? Which wires should I connect to which pins please?

You can also take a old USB cable and cut the mico USB end off and strip the wires back then touch the read to the + on the battery and the black to the - on the battery for a minute or two

or mini usb, or even an old usb printer cable, with the chunky end, , it doesn't matter which type.

Thanks samsamuel,
Seen the +/- signs on the back of the battery late, after having meassured the voltage, which is 4.14V (should I do the USB charge then even and how long is it safe since my battery powers up another HD2)?
TIA

if teh battery works in another device, then no, theres no point, its not that.
4.14 is fine, i think it goes up to about 4.2/4.3 when full, drops to the low 3.x when drained.
If the freezer trick didn't help either, then its gotta be either hardware, or something totally catastrophic, so if its an option for you, id try JTAG, failing that, id be considering using it for parts, , buying one with a cracked screen perhaps, and swapping your screen into it, ,
dont take my word for it, though, read learn and try things, you never know.
