Fix for dead hd2 winphone 7 fter battery discharge

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

Will not boot, powers down

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

Magldr quick question

i have an hd2 with a dead battery and when i go to power on the phone while connected to the wall charger it just vibates once. this is a sign of a dead battery and magldr 1.2 incapability to charge while off right?

yep, either borrow another battery to flash your phone back to winmo so it ch=an charge, , or, , charge in another winmo hd2, or, get an old usb cable, cut off the usb head, find the red and black wires, bare them, hold red to + and black to -, plug into wall charger for a m inute or two, battery should have enough charge to boot enough to start charging.

Use clk allows charging in off state plus in my opinion better touch screen response.
Sent from my HTC HD2 using XDA App

another quick question. is it correct that the only way to power on the phone is by the power button or the reset + volume down combo with magldr 1.2. because my keypad broke and im waiting in the mail for another 1, and wanted to know alternate ways to power the device on besides the power button

If its latest magldr it detects the insertion of power and turns on. Charge your battery a little, and when you plug charger in it should fire up.

Wait, wait, wait!? Sam couldn't get cLK to run properly?

no what im asking is if my phone led dont light up while connected through the charger, and the phone only vibrates once and never powers on. does this mean the battery is dead. i read several places where magldr 1.2 doesnt charge while its off.
FYI-before i changed my keypad i sucessfully flashed an android rom and the correct radio and hard spl. so i know its not bricked.

none of the magldrs charge when off, but the latest one 1.13 (where you get 1.2 from? 1.12 perhaps?) detects when it should start charging when off, and turns on.
I had to do that usb lead thing i talked about last week, let the phone die, couldnt charge it. worked no problem.

did you get the symptons of a single vibrate and no power when you tried to turn it on? *crosses fingers*

as in my PM, not that i remember, BUT, the phone does give a little shake when it turns on normally, so i can imagine an almost flat battery might vibrate then go straight off a few times before the battery is truly flat, and you shouldnt keep trying, save teh dregs of power, and try top it up as noted with an old usb cable. doesnt have to be micro usb, any old normal usb cable will do, black and red wires to - and + for 30 seconds in the wall charger, thats what i did.

[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
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

[Q] cLk 1.5.0.3 led stay on

Hi guy
with cLK 1.5.0.3 when my HD2 is off and under charge, I have to remove the battery also when I unplugged the cable the orange led stay on, and as if I push the power button, the phone doesn't start on.
It's normal? There's a solution?
Ps. With phone off and usb cable is plugin, the battery charge.

AFAIK, if you want to boot your phone you have to remove the cable first, wait for the led to go off then boot. (for cLK)

Hi,
Could you do me a favor and try this?
While your phone is turned OFF and connected to AC/PC
press once the left/green/answer button and tell me what happens..
Regards!

^HW Buttons should light up without the phone booting, but mine works just fine. All I have to do is remove cable, wait for led to go off (and it does) then boot up and it will boot just fine.
Btw, by cLK 1.5.0.3 you mean cLK 1.5 rc-1, right ?

Well, when I press the green/answer button - NOT the power button,
HW buttons light up AND my device is booting into Android, so no cable removal is needed.

If the phone was charging in sd android with screen off then it is most probably because some of the sd kernels are not patched for clk, nand kernels have most of the sod(s) fixed iirc.
If the phone was charging when was switched off (off mode charging) then unfortunately it is a known issue but not in clk, the issue is with offmode charging binaries in recovery which are apparently closed source it also could be because the power button does not behave like normal GPIO keypad button, it is not part of the keypad matrix.
If i get time after working on the maglk wrapper and my sat test next month, ill give a go at it before getting back to usb host for leo. you can get more info about recovery part of offmode charge from arif-ali and read about micro-p and gpio keypads on google or the linux sources for any htc device.

OK, this is strange.
It seems I haven't charged my phone while turned off for quite some time and I forgot the trick to turn it on without removing the cable..
So, I just did it and it worked like below:
Turned off the phone.
Plugged the usb cable.
While the phone is off and charging I pressed call button. The buttons switch on for a while.
When the buttons switch off, I pressed once again the call button.
The led switched off and the device booted into android without unplugging the cable.
Why/How does this work?
I don't really know, cause I didn't spend any time looking into it,
but my guess is that at step #4 we select "reboot system now" from recovery's menu, so the phone actually reboots from recovery to android system - it does not power on.
Regards

I've tried for the last time. I wish a new version of clk came
Also this trick doesn't work.
Thanks to everyone

strangely in clk you can also turn the phone on w/o unplugging charger by pressing green key>pause 0.1s>press home key, hold both keys and wait for led to go off and then press power
do you know why that happens?

I got the same Error when I flashed cLK 1.5.0.3. But when I use 1.4.0.1 and CWm Recovery 3.0.1.4 i can charge the phone while it's powered off and press the on button to power it on. So it might have to do something with newer versions of clk and/or cwm.
