Restart loop while charging, Cant boot with Boot Loader. - HD2 General

Hi,
I have old T Mobile HTC HD2 with Android, (Used one, I received as gift from my friend)
This rom from http://forum.xda-developers.com/showthread.php?t=1022108
It have slow charging, but today, i found it with restart loop if in charging and not boot at all without charging, just boot with splash (Stick together) and vibration plus, then it restart again, the screen only light for less than a second, same when i try to boot to Boot Loader (VOL Down when boot) it show 3 colors less than a second, it cant boot with Boot loader.
I cant boot to make any Hard Reset.
Is it battery failed, or the it is Phone problem?.
The charger USB in the wall, also i test it on my PC, same.
Thanks in advance.

Could be bent battery pins, or flat battery. Magldr will not allow charging when android isn't booted, so if the battery is very low it cannot boot far enough to start charging, in which case see if you can charge the battery some other way, either
1 in a hd2 running winmo or cLK,
2 borrow / buy an external charger
3 cut end off a USB cable, bare red an black wires, connect black to - red to +, USB into wall charger and hold there for aminute or two.

Thanks samsamuel

Bad Magldr, i think it is the reason why failed and restart.
1 in a hd2 running winmo or cLK

I will try cLK in the feature.

Good idea, but (3) is more easy.

If it is safe, I will buy female jack and take this wires from it, or maybe build external charger (IDK if it good idea).
Thanks

ive done it three times, plus i did teh same with a PMP battery that was discharged. works a treat. you can use your fingers to hold the wires on teh battery, you wont get a shock.
A minute is usually plenty (assuming you are using the wall charger, , if you are using a usb port, perhaps a touch longer.) as charging qwill start about 30 seconds into android boot sequence.

Worked, I get an old USB extension cable, cut it, and used the Red and Blue wires, but the problem in that cable the Red wire is (-) and the Blue wire (+), i used Avometer to test it before using it to recharge the battery manually (Oh my fingers) with 2 minutes, now my phone come alive and recharged again, Thanks samsamuel

[Q] HTC HD2 running nand android will not turn on after battery died

Hey everyone been using this thread for a few months now it's so useful and I appreciate all the help. I know this has been posted before and I tried all the steps listed in the other thread but last night I let my phone die and when I plug it in it just boots up until the dark forces team screen before it starts over again i tried all the steps listed to get it to charge it just seems not to work. I was able to get into the magldr screen if I plug it in and hold volume and power off. From there I choose to power down and as long as it stays plugged in the orange light comes on but when I try to power it on nothing happens. Any advice would be greatly appreciated. Thanks so much
you cant charge it powered off without winmo, simple.
2 options, borrow battery long enough to flash wnmo on your phone, use your phone to charge battery, or put battery in another winmo hd2 to charge enough to start android. (or, let it sit for an hour or two, they sometimes recover a little charge, perhaps enough to boot. Boot with the usb in, cos ability to charge kicks in about half way thru teh boot process.
just to add a third option to my last post, , i let my battery die stupidly today, completely dead, , took an old usb cable, took the end off, black wire to - and red wire to + on battery, plug in usb cable, bite nails and worry for 1 minute, enough charge in battery to power on phone and boot enough for actual charging to start!
phewwwwww.

clever! brave! i like your attitude man
heh, not that brave, i didnt do it till id read about a hundred posts of people doing it on various devices.
@bakse, whats to explain?
get a usb cable,
cut the usb end off,
strip off the silver shielding,
find the red and black wires,
bare the ends,
attach the ends to the battery,, red to +, black to - (it says on the battery which is which)
plug in the usb cable.
After a minute, remove the wires, and try the battery in the phone, and hope it has enough power to start to boot and start to charge.
I read a fair few posts where people were holding the wires to the battery by hand, it is after all only a few volts dc, but i just wasnt that brave and went for gaffer tape.

Ha ha I have been a electrician for 15 years now and I can tell you with 100% assurance that the very small voltage that it takes to charge the battery of any cell phome will never ever affect you in any kind of way. You know I had often wondered if you could charge the battery in this fashion but was not completely sure as my I do not have a full understandimg of yhe iom bstteries yet.

hehe, i did 3 years as an electronics tech in the RAF, (long time ago) so im not usually that nervous around electricity, but i was last night, , generic 3 pin usb charger, generic usb cable, stories of batteries bursting, ANYTHING could have happened!
Ive tried it again today on an old dispensable htc elfin, held it for 5 mins, which is far longer than any posts ive read. Battery got warm, but not worryingly, and when i booted the elfin it had 2%, and managed fully booting plus ten minutes use, and id drained it completely before starting.
Im glad ive tried it, and now i hope i never need to do it again.
I just accidentally let my HD2 drain the battery, but this is the first time it hasn't come on. I did the USB cord trick and it seems to juice the battery, but when I finally got to the menu me being so caught up in the excitement that my phone wasn't bricked and that I could get it running again forgot to plug in my phone to be charged and it died again... Now I am using the hacked up USB cord to charge my battery, but is doesn't seem to charge it very fast and after about 10 minutes of letting it sit I get to the boot screen in Magldr but the battery dies mid boot. Now my question is should I leave the battery to be charged with the red and black wire USB trick and how long can I let the battery charge like that will it be fine for a few hours? Thanks for your replies in advance.

I don't know if it would be safe to leave the wire connected to the battery that long. To be safe I would only leave them connected to the battery for 15 to 20 minutes 30 minutes max. I would also monitor the battery making sure it is not getting warm/hot or that the batterry does not start to swell.As either of this things are signs that you should disconnect the wires.
Well it worked I got it charged to 5% and it took forever, but when I put it in my phone and it booted it said it was currently charging, but when I woke up dead again...
Charge with wall charger, not via PC,, the current of PC charging is way lower, so for an almost flat battery it may not be enough to both charge and run the phone.
Ive been doing this usb cable hack/trick what ever u wanna call it for a few days now my usb port is completely busted and ive got wp7 on it struggling to find anyone near me that will fix it as im not brave enough to take the phone apart and replace the micro usb port
HTC HD2 running NAND won't turn on after battery died
I spent couple hours last night after my phone accidently died and was unable to turn on even charging with wall charger, I read about trick with cutting usb or charging cable and attaching wires to the battery. Finally, I found great solution by myself. I simply connected phone to my car charger and in less than 1 minute it started Android and after couple minutes I was able to move my phone back to the wall charger
actually you can charge the battery with whatever you have handy.
I charged phone batteries with anything ranging from wires cut off from just about any li-ion phone charger (older nokias, samsung and se preferable), solar panels, other batteries (3 standard aaa alkaline batteries in series will do the job also - almost no risk to phone battery) electrochemical reactions (the best one, getting electricity from mustard using copper and zinc electrodes - also worked but you need 6 "custom made" mustard "cells" ), any sort of usb port etc
My choice depended on whatever i had handy at my disposal at that particular moment.
I also powered up phones with empty (or if i suspect them to be dead) batteries by placing 3 aaa rechargeable (ni-cd or ni-mh.. NEVER USE primary-non rechargeable batteries or any sort of alkaline/carbon based chemistry) batteries in series with the + and - leads over the ones in the phone but WITH the original phone battery connected (it won't work if you simply supply the phone with 3.7 - 4.3 volts.. the center phone battery pin is needed).
They all work and for a one time quick emergency charge, it will be fine (just don't make a habit on doing these to often).

My battery run out and it wont charge it when phone off

My htc hd2 wont charge and it wont turn on i need help i have the androind 2.2
NEED HELP!!!!
Hi,
Please read this thread.You might find some useful information in there.
http://forum.xda-developers.com/showthread.php?t=1028841
Either
1 borrow friend/shop with a hd2 running winmo to charge your battery,
2 borrow / buy battery to flash winmo then use your now winmo phone to charge it,
3 buy an external charger,
4 take an old USB cable, cut end off, strip back and find red and black wires,,red to plus on battery, black to negative (marked on battery) plug into USB slot and hold wires there(fingers are fine, you won't get a shock) for 30/40 seconds. Should be enough charge to start booting, charging will start about halfway thru boot, so get proper cable in straight away into wall charger.
I've successfully used 4 twice.

Hi,
I heard someone say,that if you have an old cable,and cut off the phone end and touching the terminals on the battery,it will give just enough charge to boot on.
Then plug in asap.
cant you get to the magldr menu and leave it there to charge?
You can't charge in MAGLDR... it's disabled.
get an old usb cable, mini or micro, doesnt matter, cut end off, bare the red and black wires, remove battery, black wire to battery - terminal, red to battery + terminal, plug into wall charger, hold wires there for about half a minute (can use your fingers, wont get a shock) or use PC usb socket for about a minute (lower charge on USB compared to wall charger), reinsert battery, turn on, plug real cable into phone and wall charger, and the charging light should come on about half way thru android booting.
Done this three times now with no problem, except the first time i didnt give it long enough and it died again whilst booting.
is this REALLY my only opinion?
Cant believe it.. :/
Thanks anyway, gonna try this
No, there are other options, but they involve another hd2 running winmo (or cLk) or buying an external charger.
How can i charge it with CLK?
Right now you have to do the wire trick. And when your phone is fully charged, you can flash CLK instead of MAGLDR. CLK is able to charge when phone is swiched off. Another option is to not let your phone go completely dead. )

[HOW TO] Startup/Charge HD2 with dead battery

how to fix a dead battery:
this fix is for when you can get into MagLDR but not into Android or WP7
1. startup phone
2. connect your phone to a charger
3. go to MagLDR Mass Storage mode and leave your phone in it for about 5 - 10 minutes, then start an OS and charge it like you normally would.
this fix is for when your battery is completely dead (direct shutdown after 1st splash screen or not even starting up at all) (will work on any phone)
(DANGEROUS!! watch out and DO NOT touch the cables when they are connected to electricity)
It is highly reccomended to use an external battery charger (like this one)
http://www.ebay.com/itm/Battery-AC-...114546?pt=PDA_Accessories&hash=item3f06ce2bb2
See the attachment. (paint FTW)
1. get an old usb cable
2. cut it open, and take the wires out it
3. seperate the red and black wire from the rest
4. take your battery out of your phone
5. put the usb cable in a usb charger
5. hold the red wire against the (+) and the black wire against the (-)
6. plug the charger into the outlet
7. keep holding it for 5-10 minutes
8. TAKE THE CHARGER OUT OF THE OUTLET
9. put everything back together and startup/charge your phone like you normally would
I did the above fix 2 times and it works perfectly but it is not recommended
an even simpler fix is to just plug the thing in and let it charge. If the battery is completely dead it will take abot 15 mins for it to get a charge sufficient enough to turn the phone on. I have run my phone completely down to where it just turns off and all I do is plug it in.....

When using magldr the phone will not charge when it is of. You just were lucky that there was enough battery left to boot it up far enough to charge again after it was turned of some time.

Hd2 not getting charged!!!! Pls help me

Hi Folks,
My HTC HD2 Android not getting charged either by a wall charger or usb via my pc... i dont what happened suddenly it got turned off due to low battery and when i pluged it for chrging its not showing orange LED notification of charging. when its off and plugged in Orange LED blinked once and Phone got switched on. And when its connected to PC for abt 3 mins it will show charging and after that it shows discharging and battery drains when it shows it discharging . pls help me out coz i dont want to loose my Leo .
Thanx in advance,,,,
Check the pins at the phone which connects to the battery. Sometimes they are deformed and this cause the charging/not charging problem.
But... in this case I don't think this is the problem, because this problem should not affect direct charging from usb cable.
Anyway check them just for sure!
Thanks VDodi

Best way is not to let it run out
However, normally it will have enough charge left once it dies to boot up far enough to start charging. If this is not the case, then you have to cut open a USB cable and use the red and black wires to charge the battery. I have not had to do this and am unsure as to how to do it but there are tutorials. It seems simple enough.

Consider, as was previously suggested, a cable connection issue.
While you do not currently have the luxury of looking at your status icons, I have found that, on occasion, when I plugged in the phone to charge, the status icon indicated a USB connection, rather than a charging icon. Unplugging the cable and re-inserting the cable fixed it.
Note that new high quality cables can exhibit the same issue.
You have nothing to lose... Give it a shot.
Good luck.

Take out battery, plug chopped up USB cable into wall charger, use fingers to hold red to + black to -, count to twenty, battery in phone, phone into bootloader, real charger cable into phone and wall charger, leave 10 mins, reboot into android. (Can charge all the way in bootloader, but it seems slower than when android is running.)

By 'tutorials on how to do this' I basically meant your posts
As previously said if you're using magldr you need to be booted into Android before the phone will charge. You can try to warm the battery up in your hands to squeeze the last bit of power out of it to boot up. Or there are standalone hd2 battery charges you can buy from eBay that charge your battery outside of the phone, they're pretty cheap.
Sent from my HTC HD2 using XDA App
As Samuel said you can charge phone in bootloader. Just try!
Had to buy external charger
item # M00366 this charger was cheap has led's that change from red to blue as the battery charges and has a usb port so you can charge a battery in phone at the same time.
I'd been alternating tween an extended battery and the original when my HD2 started discharging while plugged in. same batteries and nearly a year of typhoon's excellent ROM progression then wham dead batteries....
