hardwarre problem on wing

so i think my wing may be in the process of biting the big one. A few days ago, my wing restarted itself for no reason, i figured it was probably a system error and didnt think twice about it. Now all of a sudden my wing will constantly restart, sometimes in the middle of a call. Sometimes when it does restart the screen will either turn white or fade to white. I reinstalled the original rom to see if it was a software issue and it is still doing it. Also, it doesnt normally do it when it is just sitting there, and sometimes i cant turn it back on. Any ideas?

Make sure the battery isn't loose inside the case... and that all the prongs are making contact.

For the life of me, i cant figure it out. I know it has to have something to do with the phone not getting power. At this point, it wont even fully turn on. Short of taking it apart and checking the solder, does anyone have any ideas?

If you already reflashed the original rom, and it is still doing it, that tells you it is definitely a hardware issue. It does sound like it's losing power which could be a host of things. (loose battery, defective battery, loose solder on board, etc) I would try what duprade said, and check to make sure your battery has a good connection first. If you had a friend that had a wing as well, you could try his to make sure it's not the battery.

Brand new battery (free from tmo to replace the dynapack) Everything on the mainboard looks like it is soldered well. There is an internal watch batter though, could that have something to do with it?

I doubt it. I would guess that's the cmos battery. If that were to go, then your phone wouldn't keep time, but that wouldn't stop your phone from functioning. (I used to work in the service center at a computer store).

maybe its the processor then. sometimes, after it freezes, it artifacts before shutting off

There is the possibility of you overclocking your phone, and it heated up and could have burned or cracked some solder. It might even be overheating and that's why it reboots. At any rate, it def. sounds like hardware though. Sorry man. You could try to resolder the connections on the board just to make sure, but it sounds like you have a paperweight. Is it under warranty or do you have insurance?

only ever oc'd once, for a few minutes, and not very high (like 267 i think) It's on right now on the power cable (this wouldnt work yesterday) I honestly have no fricken clue whats going on with it.
Is it possible for the battery to completely diminish itself without being used for a day? Before it died on me last, it had a full battery, now it is showing 1% (and charging).
By the way, as I stated above, it is a brand new battery sent to me by tmo.

Dang it all! Stupid thing just shut off again... ARG!!!

Hey dcmtnbkr. I seem to have the exact same problem with my Wing. It shuts off for no reason, and it does it absolutely randomly. Sometimes it would work for 3hrs straight no matter what i use it for. And other times it shuts off every 30sec. and it takes 3 to 10 tries to turn it back on(most of the times it would not get past the windows mobile welcome screen). I was gonna flash it with the newer Rom, but i'm afraid that the damn thing might shut off during flashing . So i'm stuck. If you find the way to fix it - please let me know.

actually, i just talked to tmo, and apparantly NOW after i told them I'm cancelling when my contract is up, now they can apparantly cover it under manufacturer warranty (as opposed to the last time i called about a week ago) I would call them even if you didnt buy it from them, tell them you dont remember where you bought it, but it was some company online. These phone's arent that old and you may still be under the manufacturers warranty. Also, i would try and flash it back to the original. These phones are very hard to brick, and i would ask around to see if a powerdown in the middle of an upgrade would do it. I just got mine to reflash without a problem.

my wing rstarts itself wen i jus tap the back of it where the battery cover is but it wont restart everytime. anyone have any ides?

HD2 freezing alot

No matter what build, what OS I put on it, I cant do ANYTHING with out it freezing.
AND I MEAN ANYTHING....what ever i do, what ever app I start, 2-5 mins later the phone freezes.
what sucks ever further is no matter that WP7 ROM I install, it refuses to boot past "GO, GO, GO"
I've tried task 29, different radios, still no gold

To solve some heating you need to remove the SIM card. But whats a phone with no SIM right
The only way to fix it it to either doing it your self or send it to HTC and once you get it back, sell it.
I had the same problem, once I get it back ill sell it and buy an iPhone 4G. I love the HD2, but it freezes so much.
Call the repair service.

still doesnt work, its pretty much dead now, wont even boot into winmo sometimes and cant do anything on it anymore...atleast i dont have to worry about getting rickroll'd cause it usually freezes after 5-7 seconds on most YouTube vids

im having the same problem but it started after my HD2 fell on the ground facing the screen down.. after that my phone started freezin randomly and i have noticed that it get stuck when there is a little press from the back near battery pin and near SD card if i keep the phone without any press on above position it stays as long as it get pressed again is there anyone out there knw wht is happening to my phone

I have the same problem, what usually works for me is to pull out the battery and let it rest for around 2 minutes.
Then pop it back in and let it load the ROM. After the ROM loads.. wait at least 5 minutes before you do anything.. it usually holds on, but there's always the hang somewhere after wards
It is really frustrating.. any specific hardware fault, maybe I can fix it myself.

You can buy the board and do it yourself if hou want to. You just need a small hex head screw driver and to be very carful taking your phone apart. I can not remember tbe exact location of it but there are links to some leaked official HTC training videos on desassembling and reassembling the HD2 here on XDA, but the videos are on pocketnow.com. The board recuires no soldering abilities as it has the camera and screen have ribbons that just plug in.

i suggest checking the battery pins also, make sure they are straight and shiny!

yea im gonna send it in, turns out the main board is overheating and that mean its pretty much dead...if the back gets really hot and it freezes on you, chances are your hd2's not far from death

RE: disassembly video
here you go. in case you feel brave enough to do it. it's pretty easy. i just bought a new htc HD2 for $105 after i drop my samsung captivate...i bought it knowing the screen was faulty and use this video to help take it apart. afterwards the screen is more responsive now

I have the same problem and that is too irritating... Pins are straight and shiny

The only way to fix it is to uniformly bake the board at 210-220*C/430*F (but no more that 230*C/450*F or the PCB will start incinerate) for 20 minutes, (thermostat controlled oven (for toasts) or better infrared heater, NOT MICROWAVE!!!), this will reflow broken connections and solve most cases of freezing. Keep your eyes on temperature, open oven after 20 minutes and let it cool down, don't move anything until in cools to room temperature. Start heating from room temperature and slowly bring it to peak temperature during first 15 minutes and keep for last 5 minutes peak temperature (about 210-220*C).

HD2 Bricked?

Last night, I noticed that ROM Manager had an update in the Android market
(512mb LEO with Typhoon Cyanogenmod). I hit the update button, and walked away for a while while my phone did its thing, as usual.
I returned about 15 minutes after and noticed that my HD2 was off. I could not, however, turn it back on.
Removing and replacing the battery did not help. The phone wouldn't charge via the wall socket.
My linux PC will not detect it (I checked my dmesg log when plugging in and turning on)
I left the battery out overnight, plugged the phone into the wall, put the battery inside. No luck.
I checked the battery voltage with a multimeter, and it reads about 3.9v.
I don't think it's the battery. I think my HD2 is somehow bricked! Is there anything I can do?
It's not under warranty any more, but if I send it for repair, do you think they will deny it (because it has Android on it)?
Enlighten me with your wisdom, XDA! I don't want to say goodbye to this amazing device!

It is a little late for me to mention this, seeing as you have sent your HD2 in for repairs all ready. But your power/end button may have stopped working, if you still had the your HD2 you could try pressing the reset button by the SD card slot and see if the device booted up then. But that is not an option now.
If all you did was update ROM Manager via the Android Market. Then it should not have bricked your HD2 in any shape form or fashion. Further more it should not have caused your HD2 to turn off either. I mean when you are running NAND Android on the HD2 you are pretty safe from bricking your HD2 because both MAGLDR, cLK, and the actual Android ROM is flashed to the ROM partition of the NAND memory and never touches the real SPL bootloader partition of the HD2.
Plus did you check your battery pins before sending it in? One might have been bent slightly. Or it could have been dirty battery terminals not allowing a good connection.
Point is I very much highly doubt your HD2 was bricked. You probably just missed judged your situation is all. As far as will they fix it? If you are willing to pay the fee they charge then yes.

Hah. I don't know where you assumed that I have already sent it in. I'm the kind of person who tried to fix it myself first
Pressing the reset button doesn't do anything. I tried holding it down while inserting the battery too, and nothing,
The battery pins do not appear to be bent or dirty. I gently pushed them upright, and down, and scraped the surface gently in case there was any layers of dirt, still nothing.
I have a sibling with an HD2. I can test the batteries later.
Do you think somehow, the NAND can be worn from multiple reads/writes until it dies? It is flash memory after all, and that last write from the update could have pushed it...

Hmmm sorry I thought you had sent it in for repair already. Guess I miss read that, my bad man.
Yes NAND chips are rated for only a number of flashes. But that number is very high. I can not remember the exact numbers right now but hey that is what google is for right? But you did not flash a ROM you just uninstalled a app and then installed the updated version of that app. But then again I guess when you install or uninstall a app it is performing a some what similar action. Still though flashing a ROM is flashing a ROM, and installing a app is installing a app. One is a a lot different than the other.
My money is with your battery being bad. I mean like I said updating your ROM Manager should not have caused your HD2 to turn off at all. Try your sibling's battery and report back, I really hope that fixes it for you.

I haven't actually installed any Android ROM myself. But I did lots of WinMo ROM updates. What strikes me is that you installed a new ROM through the Android Market. Is that a normal procedure to upgrade an Android ROM on the HD2?

Hmm... I have an interesting development.
I tried my sibling's battery, and it didn't help, but what I did notice is that the phone vibrates slightly when I turn it on (as it should), but it does so very weakly. So weakly that I need to put my ear against the phone to hear it.
I don't think it's the LCD, because the charging light still doesn't work.
It probably needs a new mobo.
Any suggestions before I take it in for repair?

Yeah I agree with you it sort of sounds like something in the main board has malfunctioned. My guess is the processor or the NAND chip one. I would just send it in for repair if I was you. Maybe your HD2 just finally died, I know it sucks. But if you are willing to pay for the repair then you should be back up and running in no time. I am assuming you plan to send it to HTC for repair right? If for some reason they do give you a hassle about Android being on your HD2 and will not repair it. Then contact me I might know somewhere you can get a new main board put in it.

I got my HD2 back today.
Apparently it's not worth fixing...
I also got robbed today... Just my luck.
I cannot afford any other phones atm, but what do u think would make a good candidate replacement for the future? I don't think any other phone has the same kind of mod-ability and support here at XDA, but I would be delighted if you could prove me wrong.
My friend has a Galaxy S2, which is cool, but it doesn't have notification LED :/
Is there much hacking/dev on the GS2?

[Q] Help fix my 512Leo

Alright, so here's the deal. I came into possession of a Euro HD2 recently. I have been using my personal TMo HD2 for a year or two. The problem with the Euro one I was given is that it refuses to boot past the splash screen. Here's a breakdown of everything I've tried so far to restore it.
The device boots into the bootloader without any problems. I initially loaded HSPL 3.03 onto it. It was originally on SPL 2.08. I've done a task29 on it several times with the RUU and device reporting it as a success. After this, I've also flashed a few radios to make sure the radio partition was fine. When trying to flash a ROM, it will either finish all the way and then boot to the secondary splash, where it stops booting, or it stops the flashing process at 3%.
I'm thinking that the NAND may be corrupted, but I'm not entirely sure. I don't have access to JTAG, so that isn't an option. If I can't fix this one, then it's not a big deal. I'll just scrap it for parts. It would be nice to have a second HD2 to sell or give to a dev, or even to use as a backup.
The bootloader reads as follows
PB81120 HX-B3
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x30
It will not accept a ROM image via SD. I can see the screen flash to the gray SD loading screen for a split second before it returns to the RGB bootloader. Currently using a 16GB SD card. I'm going to use a 1GB card in a few minutes to check that the size isn't an issue.

SD flash needs 4gb or smaller card

Sorry for the late reply. I had to acquire a smaller SD card. I've just used a 1GB microSD card. The update seems to have gone through. It hangs at gray screen where it says UPDATE SUCCESSFUL. I left it there for 10 minutes. On my 1024Leo, it always reboots on its own after this. I had to pull the battery on this one to make it reset. Then it does the same thing as before where it just hangs at the splash screen when I try to boot it normally.
Any other suggestions I might try before ordering a replacement board?

Does it vibrate before it gets stuck and feel hot?

It vibrates while powering on, but does not move past the primary splash screen. It does not heat up any noticeable amount.

this might sound crazy/silly but freezer the phone for couple min and see if that will work or freeze it and reinstall the rom. I had that issue with my second HD2 were I HSPL, radio, maglr & flash rom, reboot and would get stuck at splash screen. Searched & searched and found a thread with a member with the same problem I had and resolved it by using ice pack while installing the rom. I gave it a try and it worked for me.

So, you mean you put it in the freezer or under an ice pack while flashing or before?

What temperature does the phone have while you flash it? I had an HD2 hat always got stuck flashing. It suffered from freezings due to overheating, and during flashing room temperature was enough to kill it. I put it in the fridge for half an hour and was able to flash it back to stock then(through sd). Got it replaced from my provider.

I guess it couldn't hurt. It's just a spare device for me anyway. I didn't notice any heating up on the device at all during flashing this one.

Upon further inspection, I believe this might actually be a T-Mobile 1024Leo based on the model numbers being the same on both my personal TMo HD2 and this dead one. Someone did replace the screen on it at some point.

I don't have an ice pack handy, but I did throw it in the freezer for about 30 minutes. I then took it out and put it on a pack of frozen okra. It's flashing via SD right now. Hopefully it actually boots this time...

You have got to be kidding me.......
It worked....
I honestly cannot believe that this just happened....

the flash worked when chilled = good! that's great news.
the flash worked when chilled = oh no! that's terrible! you (almost certainly) have failing hardware.
Fingers crossed it was a one-off corruption that is now fixed, but if i were you id get some rom working and then stay away from flashing anything.

Well, it's just a backup device. I did confirm that it is the 1024Leo and not the 512 model. I'm going to see if I am able to flash again now. If it hangs again, I might just give it away to someone. We'll see. I might be able to score a TMo unit with a broken screen for cheap and repair this one. Thanks for the help, guys.

Ugh. Back to square one. It is certainly hardware related. I had it sitting next to me plugged in to my laptop. It rebooted to the splash screen again and is now stuck. At least I know how to fix it.

Alright, so I made some time to open this thing up. I found that there was no thermal tape left on the inside above the heatsink for the CPU. I ordered some small extra thermal tape that should arrive in a few days. If it helps at all, I'll update the thread.
I'm not particularly optimistic about this solution, but the alternative is to superheat the CPU to reconnect the disconnected contacts. I'm going for the safer, simpler, and cheaper solution. If this doesn't work, then I will probably just purchase a damaged HD2 and swap the parts.

Here is a link to a similar thread in which they discussed possible solutions to your problem. I hope it helps.

I read that reheating the cpu might work with adding thermal compound to cool it might work. I was gonna do it but i need to buy screen/digitizer first before I open it. Glad it worked out

Yep. I saw that thread last night. I added some thermal paste to the CPU, but didn't notice a change. Reheating the CPU would be the way to fix it. It's kind of along the same lines as the Red Ring of Death on the Xbox 360. The CPU got so hot at one point, that the solder points to the board were terminated. Cooling the board shrinks the spaces, allowing for the contacts to touch again and work until it reheats.
I'm probably just going to get a replacement main board.

Yea, adding thermal compound helps a bit. It lasts about 40-60 minutes longer than without it. It isn't a permanent fix, though. Once it gets this bad, replacing the board is the safest method to do. Cooling it down will give you enough time to backup your data to transfer over to another device or board.

My phone freezes :(

Hi, i have a SGH-I337M, with the AOSP 6.0.1 rom with root, since i can remember the phone had been pretty much hot, i didn't care much back then since i use it a lot but recently my phone started to freeze, like the screen freezes and i cant do anything, not even turn it off, so i have to take off the battery let it cool for 20 minutes and start it again, then it works about 10 or 20 minutes and then again it freezes i think it might be related to the heat. Also some few times my screen has turned green and then white and others few times i can see some sort of colored strings.
I'm pretty sure its hardware related but i don't know why it happens and if it can be repaired, do think ill have to change the whole motherboard?
Thanks in advance

Graphics chip may be the problem You shouldn't let your phone overheat like that I think it's the graphics chip (because of the color artifacts) You can try to reinstall ROM (clean installation) and flash another modem&bootloader, or even flash stock ROM. If that doesn't help then your graphics chip is damaged...There is 'repair', by changing motherboard, but it can be very expensive (if you don't find another S4 with broken screen or something else with working motherboard)

I already reinstalled the rom (clean install) and yupp, it doesn't work, the warmest place in my phone is between the sim card and the sd card, so i guess ill have to change my motherboard X_X
Anyway, thank you very much!

Have you actually tried other ROMs, or are you just a negativist?

Hi, i have a SGH-I337M, with the AOSP 6.0.1 rom with root, since i can remember the phone had been pretty much hot, i didn't care much back then since i use it a lot but recently my phone started to freeze, like the screen freezes and i cant do anything, not even turn it off, so i have to take off the battery let it cool for 20 minutes and start it again, then it works about 10 or 20 minutes and then again it freezes i think it might be related to the heat. Also some few times my screen has turned green and then white and others few times i can see some sort of colored strings.
I'm pretty sure its hardware related but i don't know why it happens and if it can be repaired, do think ill have to change the whole motherboard?
Thanks in advance

You should get CPUTemp Xposed module and stop letting your phone get hot! I usually stop screwing around with mine when the temp gets to like 50/60-something Celsius. And like GDReaper said, don't be a Negative Nancy, be a Positive Paulie and play around with other ROMs!!

my original phone screen did things like that after a pretty heavy drop onto a tiled floor. it maybe a good idea to have a technician diagnose your problem before forking out money for parts that might not fix anything.

Thank you all for your answers, i did tried to flash some other roms without success (I still have the same problem) i am afraid to continue playing with roms since my phone sometimes freeze in the middle of the android configurations when i reboot my phone just after the new installation and i don't want it to freeze in the middle of the installation of a rom.
I think ill go to a technician to see what can be done about it, ill keep you informed what was the problem
