Update at post #26 (handset returned from HTC alive and well)
Urgent help required please guys - help me rescue my very poorly HD2!
Phone is completely dead at the moment. Battery is completely dead and attempts to charge it are not working - however I'm sure it's not the battery that's the problem!
I've been flashing different radio roms this last couple of days going from 2.08.50.05 to .08 and back yesterday to .05 because while on .08, the back of phone was getting really hot and the battery was draining very quicky. Late yesterday afternoon it discharged completely while I had it on-charge!
Since then it's remained dead! Initial attempts to re-charge saw the orange LED come on for a minute or two, at which time I tried a hard-reset but it froze at the point of making the selection to hard-reset after the brief bootloader screen. On one more occasion the LED came on for say 10 seconds before disappearing again and since then - nothing!
Taking the battery out for all of last night and at least 20 times today has made no difference. Trying to charge it via (original) charger and via usb cable has not worked. No LED, no charge (though interestingly it still gets warm at the back when on charge), can't boot, no response, nothing, nada.
Helpful guy in O2 shop spent 40 mins helping me out earlier today (he's a XDA forum user who flashes custom roms from here too on his HD2). He took his charged battery and put it in mine with pretty much same result! White HTC bootscreen came on for a few secs before dying again. Couldn't start/boot up my phone using his good battery, yet after putting my battery in his phone he was able to begin to charge it, proving I think that, it's not battery that's to blame for this, but an internal fault with the power-unit of the hardware, (and/or perhaps with the charging port).
I'm convinced that the power-unit is the major issue, and that as it seems to be over-heating quicky, then it shuts down immediately from doing anything. I could be wrong of course.
Sorry for the lengthy story guys, but now feeling really low that I can't seem to sort this. If I cant start it up or get to the bootloader screen then I'm not going to be able to flash a stock rom to get this problem fixed under warranty, so as you can see, I'm really frustrated!
Any help, advice, suggestions etc would be gratefully received and much appreciated too! Thanks in anticipation.
Edit: sorry should have said that I've extensively read these forums today and found many similar (but not exact same) threads/posts, hence the new thread.
hapened the same to me, radio 2.08.. to 2.05... white screen HTC freeze....not booting.
my solution was press the two sound boutons at same time, when the screen write HTC apears....them booting at radio specs...them press one more time de 2 sound boutons sf same time....
it solve for me the booting...is strange this issuie of downgrade the radio 2.08... to 2.05..
good luck.

Thanks pack21, but at the moment I can't get it to do anything at all - it won't start, it won't go into bootloader, and I can't charge it. I'd be happy to see anything on the screen at all right now! Thanks again.
since it cant boot why dont you take it back to HTC? They will first have to repair it since they dont know it has been flashed with an unofficial firmware....They might even give you a new device!

Yeah, that's what I'm going to have to do as a last resort, but my fear is that with their tech/tools, they'll figure a way to power it up or get it into bootloader and discover it has a custom rom, and return it to me unfixed. This is almost certainly a hardware fault, as I believe it has always been warmer (sometimes very hot) at the back than it should be, but trying to prove it would be difficult. It would be great if I did return it and they couldn't boot it, but I only want to return it this way as a last resort. Here's hoping someone out there might have another solution.
Can you power the phone up with the charger and usb lead plugged into it?
Have you tried booting wth the SD card out?
If you can at least boot it up then you could try MTTY to see if that helps.
Post your outcomes back up and lets see what else we can do to help.

Thanks for input WB - I note you've helped many others out on other threads with related problems.
Can't power up the phone by any method (AC charger or USB), and because it's got no power, I can't boot it at all. Tried it without SD card earlier, and it didn't make any difference. Even with someone else's battery in earlier, it wouldn't boot up or charge even, so I'm at a complete loss. Always thought I'd need to try MTTY sometime soon - just didn't know my device might die on me before then (and its only 5 weeks old). Any other thoughts?

Hmmm, tough one this.
I know that some of the newer roms are particular about which radio you have installed else you get a problem not dissimilar to yours, ie the device won't get past the boot screen. Yours being completely dead is a new one on me.
Do you remember what radio and what rom were on the device just before this happened?

Yeah, was on 2.08.50.05 until 2 days ago, flashed 2.08.50.08 to give it a try but noticed it was draining battery fast and getting v hot at the back, so reverted yesterday to .05 (but maybe too late, maybe damage was already done, because total discharge happened shortly after that yesterday).
Hey guys (WB and any others with any possible solutions), I need to hit the pillow (11.45 pm my time now and I need to be up 5.45 am), but please keep posting any ideas that you want that you might have, and I'll give them at go first thing at 5.46 am. Thanks very much in anticipation!
I think Kholk of the Eugenia project has done a lot of work with radio roms. PM him (nicely) and see if he can help.

Thanks for suggestion WB. I'll pm Kholk in a moment - whilst it could indeed be the radio rom that caused the overheating and/or discharge, it seems that whatever caused it was catastrophic because I still can't get any charge into it, and hence I can't boot it up!
I hope sincerely other HD2 owners do not suffer this same problem at any time - it's proving a nightmare to fix.
My advice to all would be ignore those who promote the idea of allowing your battery to fully discharge - especially if it follows an over-heating handset - you may never recover from it (like me at the moment)!
If anyone's got any other suggestions for getting my handset powered/booted up - I'd be delighted to hear them. Really don't want to return to HTC with a custom rom on it!
The Radio ROM contains software parts that are critical to your device (at least for HTC devices) as it contains the OEMSBL (the radio bootloader) that boots ... ALL!
So, if you flash a wrong Radio ROM (as for example flashing a Diamond radio on Leo, or every radio that is not compatible with Leo: remember that for Diamond/Blackstone/X1/Raphael the radios were compatible) you'll get a totally bricked and unrecoverable (if not using JTAG!) device.
BUT.
You've flashed a Radio ROM and your device booted successfully, so, no errors during the flash process.
Assured that this Radio ROM is compatible with every HTC HD2 (TMOUS and EU), this Radio can't have produced an hardware fault on your Leo: it's almost certain that it is a coincidence that your Leo died with this Radio!
Anyway:
1. Be sure that your battery contacts are sane: check that they coincides with battery contacts: if you swap fast a battery you can do a wrong gesture with your hands and fold youre device's battery contacts.
2. Check the battery LED near the speaker: does it power on? (orange/green)
If the battery contacts are sane and the battery LED doesn't power on, maybe your battery is fault OR it is really completely discharged: on my old NEC e606 if the battery was completely discharged (0A, 0V) I had to charge it "manually".
However, if these two steps aren't helping, try this:
1. Take an AC adapter of maximum 5 Volts, or an USB cable
2. Cut off the end of the AC adapter (or the other end of an USB cable) and connect positive on battery positive and negative(GND) on battery negative.
3. Make sure that the cables are correctly connected and that your power source (AC Adapter / USB Cable) is connected and/or powered on.
4. Mantain this position for 5 minutes: your battery will take some power (yes, it is a really raw charging process)
5. Don't wait more than 5 minutes: it is a raw charging process and it will never stop! (well, not never, but if you wait for too much time, you'll **** your battery!)
6. Battery slightly charged: disconnect it from your power source, take it into your HTC HD2 and connect its battery charger.
If it works, well, you're saved, but I think that there is a fault with your HD2 because for a complete discharge of your battery you have to wait for weeks....or months! Or even years!
If that doesn't work, try with another spare battery that is known to work.
If your HTC HD2 doesn't work even with another battery, RMA it, HTC won't see that you've flashed an HardSPL, a new Radio and a custom ROM because they'll simply replace your mainboard.
Let me know how it goes!
Hope that this helped.

Hey kholk, huge respect for taking the time to consider this serious problem of mine! Thank you for the different options - I'll work my way through them and see if any can bring my HD2 back to life.
I can confirm that I've successfully flashed roms and radios (via SD) and never had any problems, and I think you're right - it wasn't the switching between 2.08.50.05 to .08 and back to .05 - it was probably just a coincidence that the unit got seriously hot and discharged at the same time as I used .08 (hence the reason I had just re-flashed .05 when it happened).
Battery contacts are good - checked them carefully yesterday.
I'm convinced the battery is as dead/discharged as it could be; since yesterday morning I've not even had a glimpse of an orange LED when connected to AC or USB charger (though the unit continues to get warm at the back, but doesn't get hot any more). I'll try your ideas for getting some life into it, and I've got a replacement battery on order, but as I found out with a friend's spare battery, it still won't boot up or allow itself to be charged.
I think therefore that it will ultimately need to go back, but I'm grateful for your assurance that HTC are unlikely to know that I've got HSPL/Custom Rom and Radio on there! Many thanks again for now (its so re-assuring to know that if you come across occasional difficulties, there's some good guys on these forums who will try to help bail you out)!

That's 2 bad nights sleep now, as this happened day before yesterday . Thanks - fingers crossed eh, both for getting mine fixed, and for hoping this is not going to become a common problem for other HD2 owners!
Well, if the device won't power up even with a known good battery, then HTC isn't able to power it on magically. Your hardware got a fault and the only fix for this is replacing the faulty part.
And no, HTC won't desolder and resolder a chip on your mainboard: they'll replace it completely!
I'm sorry for your dead HTC HD2 and I know how you're feeling... I've experienced the same.

Thanks again kholk. Reading what you've written confirms for me that there's not likely to be an easy fix for this and so I should give up on that idea now and just get it returned sooner rather than later for a warranty repair. If anything develops from this I'll be sure to post an update for the benefit of anyone else who might experience the same difficulty. Much appreciated again for now!

I had very similar issue on my X1 when I left it plugged into my car by accident, it totally drained the battery and wouldn't do anything other than blip a red light.
I swapped to my spare battery and the phone booted once, said low battery (was fully charged the day before) then did the same red light.
After much fiddling, it turned out that I had to leave it on charge for around 12 hours for the battery to kick back into life and boot the phone. Then it took a further few hours to charge it again!
Older devices could only be chared with a HTC stock charger (when having a dead battery), cause they delivered a little more power then custom AC chargers (like the one for your BT headset).
So I posted this issue on the boyppc wp7 rom thread but didn't get a reply at all.
Basically, after moving from Android to WP7 the extended media battery fails to charge. All I get is alternating green and amber lights when attempting to charge the battery.
I've tried the battery on another HD2 using android and it charges fine, tried it on a stock phone and it charges fine. It just doesn't seem to charge on any WP7 rom.
Has anyone else come across this problem? If so, do you have a solution (other than dual booting to android every time i want to charge my phone).
Cheers guys
The battery controller is a known issue with wp7 on the hd2, inshort, extended batteries will not work as expected, you will get batteries not working at all or they will only use the basic 1250mA
Remember we are lucky to even get to try this OS, but it will have bugs on our device

im having the same problem. i cant charge my battery and im looking for an external charger but no luck
If this helps...
I got an email from HTC accessories, if it helps here it is
"I have just been informed by our technique department that you need to update the firmwear for the battery for it to charge and work. You require wrom reversion 1.72.841.0 or later."

you just emailed HTC to ask them for help on an extended battery for the HD2 running Wp7?
and they told you to update the "firmware" to 1.72
i think there has been some confusion, the battery controller on the HD2 is different than the device this ROM was pulled from, our battery doesnt know what its doing because the drivers dont match the controller.
Run Android from the sd and charge that way, or I've read if you load MAGLDR, put the phone in usb storage, and leave say overnight, the phone will pick up the charge, not tried and tested myself but the android from sd in MAGLDR will definitely work. Pain in the ass I know having to change os but a half decent workaround until something else comes along.

magldr works, you dont need it to be in USB mode, and dont leave it over night, do it for no more than 30 min, that will give you enough to get back in to the OS, its unclear if the battery controller cuts of the charge, doing it for a long period of time "may" create some issues, like a dud battery, phone or a nice wee fire
Haha! Yeah mate, I can imagine a little fire by my bedside keeping me warm at night. It's pretty cold here but I'd rather use a blanket
Thanks for the help guys, I've managed to grab an HD2 with a broken screen to use as a charger. It's got the stock ROM on it so it should charge just fine.
I was trying to delete every files/folders on the SD card while it was still in Android OS and when it was connected to my desktop via usb cable but then when I finished deleting the files/folders and when I take out the battery to reboot the HD2 it would not turn on at all.
Then when I plugged the HD2 into a charging cable via the electrical outlet, the HD2 would turn on at the "Stick Together" logo then turned off after about 3 seconds. It repeats this pattern of turning on and off continuously when the HD2 is plugged in. It would be completely dead and would not turn on if it is disconnected from the outlet and just be on battery power.
How do I fix this? Did I just brinked my HD2? Is there a way to fix this?
Thanks.
i had this happen when my charger cable went bad one night and my phone drained down to nothing. just the boot logo like you described then it reboots.
i hope yours is the same. that the battery has too low a charge to start the phone further.
I let mine charge for a half hour then it worked.
also check to see if the battery terminals are bent a little and not letting the battery charge.
good luck

Were you running an SD build possibly?
Also as previous poster states check for bent battery pins where all 3 contacts need to be straight in line.

It is not the battery problem. I have two HD2 and I can check the battery power. Both batteries is at 100% full charge.
I just don't know how to fix this problem. Please help.
Oh, and yes, I was running the SD build prior to the problem.

SD Android should never affect WinMo, but that has to be one of the stupidest things ever. Why on Earth would you delete the files key to the system whilst in Android?

I did not know that it would mess things up. I thought that WinMo would take over once I take out the battery.
So what happened to WinMo? How come it cannot boot back to WinMo now ?
Any fix for this?
I had the same problem when installed Winmo 7,5. turned on only with cable and restarting every 5 sec.
I took out battery for 10 mins and when plugged in worked normal.(but after every turned off i had to take out the battery) and because of that i turn back to winmo 6.5 and ics android sd card (haret) and until now working perfect.

Unfortunately I have no clue. I, like you, wouldn't have expected that. Just try re-installing if all else fails I guess. Unless by some miracle it begins working again I would think this would be the only way, sorry
Also try reformatting your SD Card to FAT32 format and see if this has any effect.

In this case your issue is normal. Windows Phone (not WinMo which is seriously sh*t but Windows Phone 7.5 which looks to be amazing) runs through MAGLDR which does not support cold charging (charging when phone is off) therefore when plugged in the phone just begins to boot up in order to start charging, but cannot charge until it is booted into the OS and there wasn't sufficient battery to do that, hence the bootloop.
Hi Guys,
Since a few weeks I have a weird problem with my u8800. The first thing I noticed was that the phone didn't charge properly; after a night of charging it would still not be fully charged. I thought it would be the battery that died (tho that would be a bit quick after half a year) so I replaced it with a replacement battery. This battery showed the same behaviour within a few days. Then I replaced the charger for another one; this kept things working for some time but eventually the problem returned. I also tried Wipe Battery Stats to no avail.
What's wrong? I dont't get it. If the phone's on the charger now, the red light is blinking. It doesn't charge beyond 3% so I can never take it off the charger.
I have Aurora ICS since a few months, keeping in pace with updates.
Any help would be very welcome cause this thing makes it impossible to use the phone as a mobile phone..
Install the official android 2.2 and see if the problem persists
Wipe the battery stats (in recovery). Afterwards try to fully reload the battery (even if it keeps blinking red) and keep it on the charger for 1-2 more hours. Then disconnect the charger and do not reload the battery until the phone turns itself off. Charge it fully one more time.
After following this procedure your battery should be fine. If wiping the battery stats in recovery does not work, there should be a program on the market which does the same.
If the procedure does not resolve the problem please send the device in for repair. If the battery charge does not go up to 100% after following the procedure please do the same. This is a hardware error.

Hi,
I wiped battery stats but charging won't go beyond 5%. What is the name of the app you talk about?
FORGET wipe battery stats, everyone knows that is placebo!!

I would do that, but it seems risky on a battery with only 5% accu left. AFAIK you cant do these operations with the usb connection as power source right?

Plug your phone to the charger (not usb) and you shouldn't have problems...
But how do I flash 2.2 without usb connection?
Format sdcard and put update on it with some adapter or go CWM > mounts and storage > USB mount.

Put update file into the sdcard/internal card, plug the phone to the charger, and start the update by simply press Vol+, Vol- and Power.
Simple

Sorry for asking, but is there any clear reason why you guys expect flashing 2.2 might help? I ask because I expect this will cost me quite some time and I am trying to see what my succes chance is.
And, do you think I would be able to go back to Aurora ICS after flashing 2.2? I wouldn't want te be stuck on 2.2..
Thanks!

Because 2.2 is the most stable rom/kernel. This way you can see if the problem is with your actual Aurora, or it's an hardware problem.
And yes, if you flash 2.2 you can go again to 2.3 and then flash Aurora ICS.
And please, read/search a little bit on the forum before placing those questions. Those questions have been answered a million times!

Not everyone knows that, at least I did not. I thought that maybe the ROM just wasn't showing the information correctly and therefore suggested wiping the stats. But if it does not work, forget it.
In this case flashing a different ROM won't help. A battery that cannot be loaded is a hardware defect - there has not been a single report that switching to Android 3 or 4 leads to this problem. The charging of the battery is only hardware-related (if it was software-related you would not be able to charge your phone when it is turned off!) and therefore the only possibility is that the device is defect.

Because 2.2 is the most stable rom/kernel. This way you can see if the problem is with your actual Aurora, or it's an hardware problem.

This is wrong as I just explained. The charging process does not depend on Android or any software the OP could modify/change.

Not everyone knows that, at least I did not. I thought that maybe the ROM just wasn't showing the information correctly and therefore suggested wiping the stats. But if it does not work, forget it.
In this case flashing a different ROM won't help. A battery that cannot be loaded is a hardware defect - there has not been a single report that switching to Android 3 or 4 leads to this problem.

As I said, it is one of two: it could be a problem with Aurora installation or an hardware problem.
Install 2.2. If it is a rom problem, it should work right with 2.2 (it could be some kind of problem during the installation that have corrupted some files.)
If it is an hardware problem, it'll continue to have the problem. Simple

Please read once more; I stated why the Aurora installation has nothing to do with this. I cannot explain this better than I already did, but I'll try again if there is something confusing.

I don't have this problem with X5, but I've tried to fix it on a friend's other android model.
The behaviour was similar, the battery never goes to 100 % and can show from 80% 1% after minutes, and phone deactivated.
First I thought that was rom' s problem(had a CM7 custom rom), so I made a full wipe.
Problem doesn' t solved. After I changed the rom with another one(Ligux), but problem still there. Then I tried to charge it with another cable and without to power on. No difference.
So, I've flash the official rom. After that I managed to charge it normally until 100%. And seems that working fine now. The official roms change more things on the device than any custom, and seems that this problem caused from another part of the software which doesn't belong to system or boot.img(these are the parts which custom roms usually replace).
If you read the official PDF file that comes with stock roms it actually specifies that you should REMOVE THE BATTERY and connect it directly via USB while flashing the ROM So 5% charge is not even needed, just remove the battery and flash a stock rom!
OK, somehow the problem spontaneously solved itself and my phone worked fine for some time. But now it's back unfortunately. This time however I saw how it started. I think this is what happens: the battery goes too empty. So the phone crashes because of that (no proper shutdown). Then when putting it on the charger it sees the battery that is too empty as a faulty battery (indicated by the red blinking led, no charging animation visible). The phone won't power on.
There's a trick to get it to turn on though: remove the battery, plug in the power cable and it turns on. As soon as the Huawei logo appears put the battery back in (or a boot loop will happen). Then, there's a chance it will start charging again (though sometimes that only happens after many attempts).
Now the question is, why does it go too empty and is it possible to prevent this?
Hey folks, i have a HD2 which isn't turning on. I received a call and it just switched off. Now there is no activity in it at all. No led when connected to a charger. I had MIUI installed on the phone.
The repair people say that the motherboard needs to be replaced which would cost approx 12000INR.
Any way i could revive it back?
Please suggest. Thank you!

You can try the the freezer trick, put the device in a zip lock bag and put it in the freezer for a few minutes and then see if you can turn it on or charge it. You can also take a old USB cable and cut the mico USB end off and strip the wires back then touch the read to the + on the battery and the black to the - on the battery for a minute or two and then try to boot the device. I sorta souds like you were using MAGLDR and the battery died. You can not charge the device while it is off with MAGLDR. So I would try charging the battery first.
Thank you for replying. You're right i was using Magdlr. I'll try what you said

I've got the exact sam prob, the HD2 was using MAGLDR, and now it won't start (except for a few times it did), but I honestly can't figure how - since once it had been charged on an external batery charger, and then it turned on and worked for a while, but now it won't work with a charged battery...because I tried using it with another HD2 phone's battery which also has MAGLDR and which works (even with my phone's battery).
The pins have been changed, and it worked then also for a while I've been said, but it's not working again now.
Any help please?
TIA
P.S. I've tried ziplock...15min...nothing :/ How to try the USB? Which wires should I connect to which pins please?

something like this
https://www.google.com.hk/search?um....0.0.258.258.2-1.1.0...0.0...1c.1.lFN-ufsMSJw
but be very carefull, if you have an external batt. charger that would be best

or mini usb, or even an old usb printer cable, with the chunky end, , it doesn't matter which type.
Thanks samsamuel,
Seen the +/- signs on the back of the battery late, after having meassured the voltage, which is 4.14V (should I do the USB charge then even and how long is it safe since my battery powers up another HD2)?
TIA
if teh battery works in another device, then no, theres no point, its not that.
4.14 is fine, i think it goes up to about 4.2/4.3 when full, drops to the low 3.x when drained.
If the freezer trick didn't help either, then its gotta be either hardware, or something totally catastrophic, so if its an option for you, id try JTAG, failing that, id be considering using it for parts, , buying one with a cracked screen perhaps, and swapping your screen into it, ,
dont take my word for it, though, read learn and try things, you never know.
