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

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?

Find a way to charge your battery and everything it's going to be just fine.Your phone it is going to work.

Changing the battery should work.

I'm new here so basically with new 1.13 or later phone can't be charging if it's not turned on?

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.

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.

Tutorial how to recharge phone when battery is drained!

So we all know the major problem with the WP7 roms.
You can not charge your phone when battery is completely drained!
Now here is the solotion. This requires no apps, no mods. Just your own handeling!
So what to do when battery depletes?
1. Plug your phone into a powersuply.
2. Turn on the phone and keep the power button and both volumes buttons pressed. (this is called a hard reset.)
How to hard reset HD2, view the first 17 seconds. Ignore the VolUp!.
3. You will receive an message saying:
''This operation will delete all your personal data, and reset all settings to manufacturer defailt. Press VolUp to restore manufacture default, or press other keys to cancel.''
Click to expand...
Click to collapse
4. Do not press anything. Let your phone be for a couple of minutes. I keep my phone laying for a minimum of 10 minutes.
You won't see the phone charging (no orange light in upper left corner)! Believe me it is!
5. After 10 minutes restart the phone. If ''press any other button to cancel'' does not work. Take out the battery, keep battery out for 5 seconds. Restart phone.
6. Phone will start. After windows phone loading screen you will see the phone is charging. If you kept it on power. If not, you didn't follow my instructions.
Tip: to avoid battery drainage!
When the phone is making the bleep noice warning for critical energy level, turn off the phone and keep it at a warm location. Ideal is to take out the battery and keep that to as warm as possible. Batterys barely drain when they are in warm enviorments.
I am not responsible to any damage done to the phone!
I done this multiple times, all times it worked fine for me!
If it helped, Thank me and leave a comment

when i'm on the road there is only one warm place i could think off, besides my armpits...
but your method works, have faced it once.

Thanks for the conformation.
To bad the HD2, is kinda big... doesnt sit that well.

magldr works as well
whats not clear is if the battery controler is in use with this method, so be warned, dont leave it too long, if you charge it for no more than an hour it will be ok
mains power adaptors usually give out 1Ah, take in to account that the screen is on full, this should give you around 700mA, more than enough to get in to windows to charge propperly
USB charge will be half that, most USB ports only give out 500mAh so an hour will give you approx 200mA again, thats enough to get you in to windows
Overcharging a battery can have some side effects, firstly is reversed polarity, meaning it wont take as much charge in the future, or it could heat up a lot, which isnt good for anything, the life of battery or the device its self.

That is true, but I recommend trying it for a minimum of 10 minutes keep it on charge. and as soon as windows pop on it recharges normally.
And didnt knew magldr did the job as well, the only problem is if you deplete it to badly it doesnt go past the HTC screen in the beginning.

all this is completely unnecessary.
easy fix solution:
1. Pull the battery out and USB cable out (if connected and charging)
2. Plug the USB into the phone and allow it to charge without a battery (it will not, duh!)
3. Put the battery in while the HD2's connected to the USB charging.
4. Observe that you can boot all the way back into WP7.
enjoy.

I did not know that.
Well thank you. Although I am not such a big fan of taking out the battery when its not needed. I mean the change is short circuits with the connecting points when taking out, when powered or putting in when powered it larger. Now I heared from a comment above that MAGLRD does the trick as well. Now that is far more easier then all the others given above, Yours and mine

good tutorial on this. I cant believe the battery wont charge when dead thought this was a faulty error of the phone.

theres 3 methods on here,
bootloader charge
magldr charge
remove battery charge
all three will benifit frm heating up the battery, do not cook it, or it may blow up
there is a 4th way but i dont recomend it unless nothing else works
take a usb cable mini or usb printer cable
cut off the end connector
strip back the wires and seperate them all, you want the red and black ones
make sure all the wires cant touch each other, cover the 2 unused wires with tape i
then connect the black wire to the (-) negative and the red wire to the (+) positive
tape them in place
the 3rd contact point on the battery isnt used in this method
finally connect the other end of the usb cable to the computer
dont leave it too long and when disconnecting remove the computer end first

It bypasses the system somewhat. Don't know what happens when battery is entirely drained, but it is worth a try.

Click Here. Its not that expensive, a official new battery from HTC is around 30$is around 20Euro's.

Thanks for this timely post Lemonspeakers. completely drained the battery listening to music on loudspeaker and didnt hear any warning. Couldn't hard reset then checked this thread.
On putting in the battery after charging the empty phone, the screen kept cycling between mgldr and HTC splashscreen so booted into sd android and the phone is fine.
I assume I didnt charge the empty phone for long enough (30 secs), I didnt warm the battery and I suppose I could have left it cycling until it charged up a bit more.
Thanks again

That might work.
Otherwise maybe a phone repair shop, there is equipment that can charge your battery outside an phone. An emergency charger its called if I am not mistaken.
you could inform there.

its showing symtoms of it bring bricked. cause it doesnt charge, it doesnt turn on without the battery, and yeah conclusion is that its dead!

[Q] HD2 Stuck in loop on power up

I had MAGLDR v1.13 with Android 2.2 on my HD2. Everything worked fine, until tonight, I booted the phone into the MAGLDR. I had the menu up for a few minutes. All of a sudden the phone powers off.
Now it's stuck in a loop - if I press the power on button, I get a vibration, and "T Mobile" logo comes up ,and then the screen goes dark again.
I tried removing the battery to no avail.
How can I fix it?
Update:
Now it's even worse: The T mobile screen no longer comes up, regardless of how long I keep the power button pressed.
Thanks!

Can you still get into boot loader? If so, try doing a factory reset on it.

It sounds like your battery might have died. I know that when you are using MAGLDR. You can not charge the battery unless you are booted into the OS. Not to mention it takes a little more power to boot up a device.
You may want to try and charge your battery some how or try another battery if either are possible.

Yep, wanted to point out the same. I had been away and couldn't get to my charger on time, so my phone went off completely and when I finally managed to connect the charger it made it all the way to WP7 startup screen and then went off - not enough to get the battery to start charging. I connected the charger, made it to the MAGLDR menu and left it for about 10-15 minutes with charger inside, then I removed the charger, removed the battery, reinserted both and was able to boot into windows and charge properly. Somehow, even though it's just MAGLDR and no charging light is showing, you can still manage to charge it just enough to start the OS. Worth a try... Although in your case it sounds like your battery is already gone beyond getting to even the MAGLDR.
The only other alternative will be to charge in another phone or use desktop charger.

Take an old USB lead, mini micro doesn't matter,
Cut end off,
Plug into wall charger
Red to + black to - on battery (can hold with your fingers, wont hurt)
Hold for about a minute
Battery back in and real usb in, and should boot far enough for charging to start.

Thank you all! It was indeed a dead battery!
How could it drain so fast, since it was about 90% when I started using it?

I feel mine is on the way out, actually. It charges etc, but acquired a tendency to go off unexpectedly and fail to start up the device beyond MAGLDR and on rare occasions beyond the logo. Discharges unnaturally quickly too. I have a spare, so not a huge deal, but I prefer to have a fully charged spare in my bag, just in case. Just ordered 2 replacements in anticipation of it dying.
Glad we could help, hehe, I bet you were tearing your hair out thinking it was your phone.
