[Q] htc hd2 auto power-on issue? - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi all,
I have 2 HTC HD2s. I have had the first one for a couple years now, flashed with magldr 1.13, cwm, and an Android Nexus One NAND rom installed. The second HD2, which I just flashed, has the same setup. However, the second HD2 will autopower on when you shut the phone down, where the first one will stay powered off. Any fixes or suggestions that I could try? Thanks, guys.

Check the battery pins on the back of your phone, and make sure they are straight.
Also, remove battery, plug into charger, wait, wait, put battery back in, magldr will boot, then android, remove charging cable, power off. ()

Ok so following the above-mentioned instructions, it turns off. However if I then plug in my phone, it turns on automatically lol weird. Is this typical behavior? My other HD2 doesn't have this problem.

This is standard magldr behavior. Use clk if you want the power off feature while plugged in.

Thank you

[Q] [NAND] How to charge an empty battery?

NAND is a new experience with HD2 but what if the battery gets empty?
Mine won't recharge.
The LED lights orange but there is no recharge.
Seems like the devs have forgotten this very important thing...
Any ideas?

Thanks, but the phone is off (battery is completely empty)...
Orange light is on but it does not charge...
Pull your battery out and also the plug. Wait one minute. Put in the adapter first, let it charge for 3 minutes, then startup the device. Pls do and report back

With the phone off it should just charge, magldr doesn't load until turned on so its not nand related
Are you using usb charger or mains?
Ok, thanks. I will test it.

You tell me if I'm wrong but he's trying to charge his phone witch has no power the phone is off and it won't charge so how is that nand related?
If it is a battery that has not been used for a LONG time then you must "shock" it to be able to charge it again. Use a standard 9V alkaline battery and connect the +, - poles to the HTC battery +, - poles respectively using 2 wires - do that for 30 to 60 seconds. Then put the HTC battery back in the phone.
WARNING: Do NOT connect the 9V alkaline battery to the phone. Only to the HTC battery which you have removed from the phone.
Lol same thing happen to me yesterday i charge the phone for 10-15 mins then unplug the phone and pull battery then start the phone once completely in android replug it. I think dft said it was a known problem for nand to not start sometime when plug in although it only happen to me when I'm completely drained.

I'll take your word for it he's probably fixed it by now anyways
Charging while phone is off is buggy for me since I installed MAGLDR.
For example sometimes orange light bulb freezes turned on even i unplug the cable, until I pull the battery.
Firsty I thought that the problem is impossible to be caused by magldr, but now lots of people with magldr installed are experienced battery charging problems ... interesting.
--
PS: Charging on Android was also always buggy for me since the first HD2-Android release.
Some of the problems (randomly happens):
1- Charging stops when it hits to %90
2- Battery level jumps from %90 to 100% while charging (according to the JuicePlotter app, it draws battery graph by time)
I'm using TMOUS HD2 and tried every single Android build since the first release.

I have reproduced this case several times,
but no, I don't have magldr installed,
only winmo and SD android.
I presume this is the bug of HD2 in general, that it won't charge when the battery level is 1% or bellow. Several occasions the phone was shut down during the sleep. Woke up and plug the charger and it always gives me orange-dim-green-dim-red-dim and so on,,, (note that this is in WinMo) and after turned the phone on, it stops charging and 15 seconds after booting, it shut off.
what I always do when I encounter this is performing battery cycles reset.
or,,, just uninstall the battery, wait for 10-30 seconds, re-install the battery, and with the phone off, charge the phone using wall charger.
These are the dangers playing with ROMS people. The rom controls vital functions of the hardware, including the way the system charges. This is a serious flaw that must be addressed immediately, and imo should not have been released if known about. The new territory of nand builds could even brick our phones permanently. I wouldnt mess around without reading reviews first. Android devs here have been quick to release builds overnight because they know it's just running off the SD card and can always be wiped back to winmo. Not anymore, these builds need SERIOUS testing first before being released to the general public.
This is caused from NAND Magldr.
If you have a cable plugged into your phone, either wall charger or USB, it will freeze when the phone shuts down.
Solution!!
Dont have the cable plugged in while powering down android.
If your LED stays orange after unplugging, pull your battery for 3 seconds and start again, it will only do this upon shutdown with some kind of cable plugged in.
This has never happened before Magldr.
This is a big issue... I dont know when Devs Team is gonna look into this and fix it...
Would it brick my phone?
No it won't brick your phone...how I solved it...discussed a couple days ago, here...

[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?

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.

No battery load when switched off, instead phone boots

As written in topic, phone boots when usb plugged in. Cant charge for battery calibration.
Using magldr, cwm, hyperdroid cm7.
Sent from my HD2 using XDA App
phone cannot charge when powered off when magldr is installed.
magldr starts the phone when it detects power so that charging can start.
That is a Magldr feature.
It boots the phone so it charges. CLK will go into a charging only mode.
Just let it charge all the way to 100% and look in the hyperdroid thread for more details on the battery calibration.
So no way to charge when magldr is installed?
Thx sofar!
Is it kernel specific how to calibrate then?

Nope, no way to charge when phone is off unless using CLK (or SD Android of course). Not kernel related as far as I know and I was wondering about the battery calibration as well. Maybe it will work with the phone on as well?
Well, best way I found is recharge when in Android, unplug, switch off, plug, charge until full again, reboot. This will overwrite Android setting for max capacity.
I dont want to set the values manual, cause u never know what cap.the new battery really has.

[Q] Its not turning on...

Last thing I tried was to put a update in sd and flash it via the sd card method and it said update failed and shut down phone and i couldn't turn it back on ever since. My question is, could it be the battery's fault? Should i buy a new battery?
first of all is it magldr or clk?
whichever it was, try using a different charger
and plug a usb cord into the computer and see if
it boots.
if not your batter could be the issue.
good luck
Sounds like it may be bricked.
Check your battery connectors and make sure their not Bent.
