[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.

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

[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!

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] 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.
