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.

[Q] HELP!!!! n10 died and now wont turn on

Ok my n10 is rooted and romed with CARBON rom, no problems nothing, but today I had an email come in I looked at it set It down left the screen on a second later it just died. so I plugged it in back on it comes. later same thing almost dead checked new email, set it down screen on then death.....plugged it in again, now nothing except a flashing battery charging symbol. been charging for 10 min. tried power, power volume down, nothing....got a different cable...nothing.....my computer wont pick it up either. what do I do?????
PLEASE HELP!!!

I just had this same problem with mine; because of the strange battery issue where my battery would read 90% when it was actually empty and slow charging once it was plugged in... The resolution for me was to plug it into the charger for 5 minutes and not touch it and then try a power on.

Thanks Ill give it a go!!

Plug it in to the wall charger, not a computer. Let it sit for 30 minutes and then hold all buttons down at the same time. This should let the tablet boot now and will bring you into fastboot mode. It defaults to "Start" so just hit the power button and the tablet will boot like normal. Once you verify the tablet will boot fine, shut it down and leave it plugged into the wall charger until the tablet is charged all the way.
Dont know if it is a coincidence or not but this is the 3rd time I have heard the same story and all people were using the Carbon ROM.

Thanks guys for the feedback, definitely will be switching roms and buy the pogo charger!

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I removed battery, reconnected after a while, still same problem.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)

I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.

I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.

Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?

Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

The battery will charge with a NCF Charger
Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.

I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.

Phone won't boot up after running out of battery

I'm running Omni rom with eas kernel and just yesterday my phone ran out of battery, and now I can't turn it on at all. At first when I held the power button, the phone would vibrate after about 15 seconds but it wouldn't do anything. Now it doesn't vibrate or show any signs of life at all; no charging led no nothing. If anyone knows a way to get into recovery or fastboot that would be enough for me to flash a new rom but I can't even get it to fastboot or recovery. Any help would be greatly appreciated.
Thanks.

What happens when you have the charger plugged in? Is it stock charging cable and brick? Have you tried checking what happens when you plug into a computer? If it is the stock cable check the end of the cable (phone side plug) to make sure there are no burns.
You can try holding the volume-down + power.

It has been charging for hours on the stock cable and brick. There are no signs of burns anywhere, plugging it into the computer doesn't change anything either. The computer doesn't detect that it is even plugged in.

Ran out of battery? Like 1% was left? That's no good. You're never supposed to let a lithium-ion battery get that low. You might have to replace the battery. Just keep attempting to charge it and boot it up again, use different outlets, different cables and adapters, etc. This is a common issue--people are stupid and just let their phones die instead of being vigilant about charging them. And there's plenty of stories about and advice for Android phones that won't turn on after being completely drained of battery life. Google is here to help you.
Did you try what slgooding suggested?

I tried holding down the power and volume down button. I usually don't let my phone die but I went camping and left my phone in my car and I forgot to power it off I guess. Still I've never heard of this happening to anyone else.

This is a real bummer. I would suggest trying another power brick and cable. That may be your best bet. See if it has any indication it is charging.

Try a different cable to charge and press and hold that power button till it boots(2,3, 5min...) it happened to me the other day... I love my LP3 keeps me entertained...lol
