Probably the wrong place but this forum is beyond navigation for newbies like me...
if you have let your battery run dry and can no longer charge and get into your win7 hd2, here's how I did it...remove sim and sd card, plug charger in, it will boot and charge again... worked for me...
I'll make sure to keep this in mind, if it works! I'll make an edit to announce my results when that unfortunate day comes.
Pulling the battery out and sticking it back in works too.

not for me. if its really discharged and i remove the battery, put it back, the charge led (orange) goes on and after 5sec its off again and nothing happens

Nope, that only works if you still have charge left in battery. removing and putting it back in also unlocks it because if you power on phone with USB in it locks for some reason. Well mine does anyway.
If your battery is completley dead then you have no choice (atm) to either charge the battery externally with a dock or by using a USB cable with end cut off (red wire to positive/black to negative).

Yes. That's what I also do many times. Never fails
No need to pull out your micro sd, it might cause your rom corrupt. Be careful!
Here's What works for me
Remove the battery .. put it back ... keep the down volume key pressed n press the power key ... THE phone will be on recovery screen... plug THE usb in .. leave it like this for like 15 mins n now reboot . It will be recharged just enuff to power the phone on ... keep the usb plugged and it will start rechaging ...
None of these tricks worked for me, and I didn't want to cut my usb cable...
But I solved the problem with dual boot. Now I can charge my hd2 when it's turned off, and I even have my battery able to charge up to 100%
I presume the phone will not charge if theres not enough power to enter WP7.
I thought the phone would charge by the USB power lead if its turned off.
I guess enter MAGLDR or the Tricolour screen will allow it to charge?

I've let my phone turn itself off twice since I've been on WP7 and pulling the battery has been enough to get it to boot up far enough to charge both times so maybe I've just been lucky or maybe the phone shuts down before it's completely discharged...
Oh man, this happened to me the other day. Battery died, phone wouldn't hold a charge. Freaked out!! But after some trial and error it worked.
Its not possible to charge the phone when its turned off?
This happened to me when I was still using WinMo. When I connected the phone to charger, it seemed dead (no led light), but after some time (I left it charging over night) it catched up and charged.
This is not possible with WP7? I wouldnt say, that MGDLR could change the way of charging when the phone is off.
keep an external charger for this problem. at least we can hope in the next update of the ROM will solve this problem
In my case, since I fall asleep while listen to music, in morning I wake up, phone already shutdown and can not boot. Even when I plug in, it boot to htc welcome then reboot.
I have tried to pull out the battery and put it back but nothing happen, my phone keep reboot.
So, I pull out the battery and charge with external charger (can charge battery only without phone). Then after 30min put it back then it works.
Thanks god. So be prepare an external charger because WP drain more power then we thought even with the warning 10%. I can not have enough power left for an over night.
This works for me.
This is known maglard issue. This steps works for me every time.
1. Remove battery and after few seconds place it back.
2. Connect your phone with PC through USB
3. Now enter bootloader by pressing Vol Down and Power buttons at same time.
4. Leave it connected for a few minutes.
5. Disconnect your phone from PC and remove battery for a few seconds.
6. Now place battery back and power up your phone.
7. You will start WP7 and now you can continue charging battery normaly.
MGDLR choose last option
it hapens to me and what i have done is in MGDLR I choose last option an it satart charging after some minutes you have to take out the baterry and reboot
it work for me
Happened to me this morning:
1) Took battery out, placed in cradle, put battery in, and held down 'POWER' whilst it booted to MAGLDR.
2) Selected USB Mass Storage Mode, waited for 10 minutes, pulled the battery out, whilst still in the cradle.
3) Re-inserted battery, allowed WP7 to boot, and orange light came on whilst booting, and started charging in WP7.
Thanks to all in this thread!

Tghe VOL DOWN + POWER works. Happened to me yesterday and after 10 minutes in tricolor I was able to boot.
Bootloader Charges Battery
VICTORY! I was frustrated, and pulling out the battery for a few seconds didn't help at all. Putting the phone in the bootloader (tricolor) screen for 10 minutes worked for me. Phone is back in WP7 and is charging.
No need to pull out battery just hold down power button boot to magdlr main menu leave charger in for 5 mins than boot wp7 (first option in menu) than shud work

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.
Last night my battery completely drained so I charged it over night and when I went to power it on it says booting WPH go go go, boots to the HTC green logo screen and powers off. I have been running WP7 flawlessly for 3 weeks now and have not had this problem before. I don't really want to reflash right now because I'm hoping there's a way to salvage everything in the phone.
Are you sure the battery charged last night...reason I ask is...when it completely drains the battery wont charge when the phone is off due to Magldr.
Yeah, it's off the charger right now and it just keeps powering off after the HTC logo
same exact thing just happened to me. I'm going to start from scratch and redo it.
I am curious to know as to what caused this, it's very odd since the ROM has been working flawlessly.
your not restarting with usb cable attached are you?
how did you charge your battery? external charger?
there is some talk that charging in magldr usb flasher mode works dispite no status lights BUT its unclear if the battery controller will auto cut off when full, overcharging could shag your battery
oh a while back i had some odd restart issue too, pretty much as you have mentioned, happened 4 times in a row then worked
Help me too!!!
Me as well, about an hour ago, my battery drained, so I plugged it in, and the phone keeps restarting, but then powers off...
I've kept it on the AC for the past hour, and now it no longer hit's the magldr, it just flashes the screen black, then dies...
Is there a way to JUST CHARGE my battery? Without having it in the phone?
too bad you didnt seach for this issue, i wrote a nice piece that would have got you out of that mess if you hadnt kept restarting it, oh well never mind,
if you cant even get to magldr then your looking at an external charger, you could try connecting up an old usb cable directly to the battery but be very careful!
This happened to my old HD2 after I gave it to my sister once I got my HD7, to enable it to charge again all I did was remove cable, remove battery. Re-insert battery and attach cable, hold down the volume down button on the side of the handset and press the power button.
The phone will turn on and show the tri-color screen. Leave it on this screen for 20 minutes and the battery will charge, then simply reboot and you will be able to boot back in to Windows Phone 7.

Thanks for that tip...I am going to remember it in-case I one day run into the same problem
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
Sent from my HD2 using XDA App
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
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
