HD2 charge from dead battery questions

I have an HD2 I just bought, should be still under warranty (aside from running wp7 and random warranty-voiding stuff) and I am noticing an issue of when I totally kill it, it seemingly won't charge (or no charge light comes on at least) until I pull the battery out and put it back in. Also, I have noticed it doesn't power on from that state (light goes from orange to green) until I pull out the battery and put it back in. Is it just because I'm running WP7 and hardspl3 or radio 2.14.50... (or whatever recommended radio is for wp7). It's not a huge deal but it makes me curious. Also I get occasional restarts upon booting wp7 but it always boots into it (maybe 1 or 2 restarts every ten boots, and it seems to happen more after total kill). Just wondering if people are having similar issues.
WP7 is pretty cool, but I am wondering how many prefer 6.5? I'm an avid Android user (never ran 6.5 except on a Blackjack ii briefly, and yes, 6.5) and I was curious what you guys thought of wp6.5 vs wp7.
Lastly, I am wanting a magldr compatible sd version of a Desire HD ROM with sense and everything that isn't overclocked (I know there are some out there that are, ie DL.DesireZ 3.x).
Please advise.

It's not WP7, it is MAGLDR. MAGLDR does not have a software in it which allows the phone to charge when off.
My advice to you, never, ever, let your phone lose charge. A dead battery is a dead phone in our case, unless you have spare batteries.

I figured something like that. It's not going to botch the magldr flash though if it dies, is it? I would assume magldr is read-only or close to or something like that to where it can't corrupt itself.

I don't see why a dead battery can kill MAGLDR, it'll just leave your hd2 unable to turn on. However MAGLDR, I assume, isn't incorruptible. Well if you're afraid of corruption from leftover flashing, for whenever you want to flash WP7, Android or winmo, perform a task 29 first, flash MAGLDR, and then the OS. Well if it winmo, then a task 29, then simply flashing winmo and done.
Oh and the reason WP7 kept on rebooting on yours was because your sd card was incompatible. My advice is to reformat the sd card with panasonic formatter, full format btw, and then reinstall WP7. If that doesn't work, you just have to get a new card.
A MAGLDR SD desire hd version I know not of. Since NAND came out, SD development has died off so there are only a few developers that still strive in that forum.

Well it restarts hardly ever so I probably am not going to worry about it. It's the stock HD2 sd that came with the phone. The reason I want an sd build is because I want to dual boot.

I don't understand how I seem to be the only one who can charge in magldr.
I've drained my battery many times to the point where it doesn't turn on to calibrate using Android. Pulled battery, reinserted and connected wall charger. Orange light comes on which means it's picking up charge, leave it for a few minutes so it gets some residual charge in it, pull battery and charger, reinsert, boot up, then during boot process plug the charger back in and away you are, charging from scratch.

I too didnt have any problems charging dead batteries via MAGLDR.
Those who are can update to version 1.13 as its now got a workaround for it apparently.

I wasn't aware v13 was even out. Well it's not a big deal. Glad everyone is having this issue . This bug still beats having to wait 20 minutes for my stock Sammy Vibrant to boot up. Damn ridiculous.
Is your battery life worse on WP7 or WP6.5? I get roughly 8-10 hours. I'm surprised it burns that much electricity seeing as how all it is is some colored squares and no data connection or multitasking.
EDIT: Updated to MAGLDR ver. 1.13 without a hitch. Will see how this goes. For the record I was using 1.12.
I guess this is the fix:
"*Fixed Power-Off-Cable-Plug-Stop. Phone now detects this situation and reboots. Battery controller inside LEO needs runtime control during charge, it implemented in OS."

I could do it on the first version of magldr, as long as the Orange light comes on you're good to go, just leave to get some charge then pull everything reinsert turn on, simple...

I found the trick--MAGLDR V1.13
Plug the phone into a wall charger. Hold the call end button as soon as the phone comes on booting into MAGLDR. Let the phone stay at the MAGLDR menu screen for about 15 to 20 minutes. Restart the phone and leave it on the charger. It will have enough power to make it to the android home screen.

sorry for the delayed reply bro but i justr had this problem lately and know abt the fix for it... just go into magldr by pressing the power key for sumtime on bootup... after that plug in the wall adapter for about 20 - 30 minutes... havng done that remove the battery and insert it agiain w/o the charger... start the phone and let it go the main wp7 screen where it will stay for only about 20 seconds... quickly run to the settings menu and switch on airplane mode and put the brightness to the lowest setting... and quickly lock the screen... the phn will start charging fine... now leave it for an hour to charge and then adjust the brightness as u like and turn on airplane mode... it will work fine... take precautions for next time... there is a kind of an odd fix that was in forums...(sorry dont have the link)... when the wp7 is working go to the default camera and go to the video camera mode and switch back to the still camera and press the windows buttn to go to the main screen... the battery drainage is very less in this case and the stanby increases... cheers!

[Q] Unable to charge..

Hi, I installed Magldr 1.13 and windows phone 7 and accidentally left my battery flat. I tried charging it but it will cause an endless reboot, i will be stuck at HTC boot screen before it reboots again. I think magldr doesn't allow it to charge and I dont have enough power to boot into windows phone 7. Is there any other ways? I tried charging at the tri colour screen and magldr but the phone keep heating up. The endless reboot is causing it not to charge! =( Any ideas? Thanks

Its well known and documented that magldr prevents charging when off.
If you can borrow another phone, and the other phone has win mo you can use that to charge yours.
If you can only get access to another battery(or the other phone has magldr too),use that battery to flash yours back to winmo so that you can charge the dead battery from off.
If you can't borrow either, you are gonna need an external charger, or perhaps buy a cheap battery.

try this:
1. remove the battery for a minute or two
2. put the battery back inside
3. the phone should remain OFF, do not press any buttons, do not try to turn it on.
4. plug in the cable...see the orange light come on.
5. leave the phone like this for 10-15 minutes.
6. now turn it on and charge as usual.
tell us if this works.
NOTE: i thought cotulla fixed the battery-charging-while-off problem in magldr 1.13?

Just boot in magldr itself by holding powerbutton on start-up and let it charge in magldr that works.

Re: the above 2 posts.
No, the charge bug in magldr wasn't fixed, instead magldr detects charging and powers on the phone.
Hectiq, sure? Never charges for me in magldr menu.(as I would expect since the software to control charging is part of the rom)

thank everyone! I left it on magldr for 30 mins and it gave me enough juice to boot in the os to charge! Anyone with this problem should just leave it in magldr menu.

I cant even get into magdlr menu by holding power key.. it keeps restarting. Is there any other solution??

go to a store and beg them to put your battery in their phone for a few minutes?

Very strange problem - MY HD2 IS DOWN

Hi for all. I'm using a imilka's Incredible Sense v1.1 NAND ROM
http://forum.xda-developers.com/showthread.php?t=963521
Everythings work very well but before 10 minutes, my phone turn off. By itself. And now I CAN'T BOOT UP! Any method doesn't work! HSPL Boot works but only for a 2sec. Then suddenly turn off And also MAGLDR. What I can do now? My phone is totaly down and bricked
And when I connect charger, phone boot up. Only to black HTC Boot screen. Then again boot and again

flat battery? might have to use bare end usb cable to put some charge into it.

Battery has I think about 10% but also when I connect charger my device boot up but only on HTC Black Screen. And then again restart SH***. All my contacts and important messages are GONE!

if you have been running android, the battery indicator isnt very accurate, so since you think you have 10%, id guess its even more likely you have a flat battery. I had one go to flat from 13% just on a reboot.
got an old usb cable? mini will do, doesnt have to be micro, , cut the end off, bare the red and black wires and hold them to the battery, black to - red to + (it shows + - on the battery) hold there for about a minute, and there should be enough charge to start the phone far enough into bootloader for charging to start.

Some news. When I press a combination for HSPL boot Vol+ + Power and immediately connect charger, phone is waiting and not boot at all. Now I'm at work but when I came to home I will try this same method with conection to my PC and flash original FW. We will see. But all my contacts are gone. Also on SIM card

Now I tried to disconnect the charger. I pulled out the battery and then I tried to start MGLDR bootloader. And it works. So battery is flat as you sad SH**. I hope that everything will be OK after some minutes charging on HSPL bootloader. We will see

cant charge in bootloader when magldr is installed, only when a rom is running. (Starts charging about half way through android boot cycle). Its a bug in magldr, thats why it tries to power on when you insert the power lead, magldr detects an attempt to charge, and starts the phone so it can.

Oh. My english isn't that great Sorry but I don't understand what you wrote. I'm from CZE so could you write this again and more easilly?

magldr does not allow phone to charge when the phone is off.
A rom (android or wp7) must be running (active) to charge when magldr is installed.
magldr neumožňuje telefon nabíjet, když je telefon vypnutý.
ROM (nebo android WP7), musí být spuštěn (aktivní) na poplatku za instalaci magldr.

Excellent. Now It works. I tried my method. I let my phone charging in HSPL boot screen. After 15min I tried to boot up again. And it works!! Uff. I almost had a heart attack

hehe, good result. Be very carefull about battery charge.

Yes I forgot because I had a lot of work and my phone was in my desk. Ok and thanks for a helpful informations

[Q] Android HD2 reboots at Dark Forces Team Screen

So I have been using my HD2 with Android installed in the internal memory for at least 6 months with no issues. My HD2's battery life has dwindled down to being about 3 hours, so I ordered a new one. I popped in the new battery and plugged the phone in, and now the phone will continuously reboot itself while plugged in, when it reaches the Dark Forces Team screen. I installed the old battery, and the same thing happens. The phone will not turn on unless it in plugged in. Also is there anyway to charge the phone while it is off? When you plug it in, it turns itself on automatically. Lastly, I don't know if this affects anything, but I did drop the phone from about 3 feet with the charger in, and now the plug has to be pushed in to get charged. Thanks for all your help guys.

1- dropping your phone with damage may certainly have caused this. did the problems start right after?
2- with magldr you cannot charge with it turned off.
3- try to boot into bootloader. is that possible?

I didnt notice anything different after dropping it, except now I usually have something wedged under the charger. I tried Loading in through MAGLDR BOOT AD NAND. No luck.

you misunderstood.
can you boot into bootloader (not magldr)? the tricolor screen- turn phone off, turn on and hold down the volume down key.
if you can (and should be able to do so) - i would start over. flash back to WM. i never do task29 though conflicting reports. then reinstall whatever OS you are using. if problems persist on WM, then is hardware. however, to flash back to WM you will need battery life (>50%) which may represent a problem. but try to get into bootloader first.

[Q] Charging While In MAGLDR 1.13

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
