[Q] Hd2 having seizures!!!

Hello,
I've had my hd2 for about 6 months now and about a month ago it started randomly crashing. I'd have to take the battery out and reset, but when i'd start about 1 out of ever 4 times it would show the inital launch screen, but the numbers in the bottom left would never come. So i'd have to remove the battery again and reboot.
Then it started happening more frequently. Random restarts, crashes, and the phone didnt like to boot at all most of the time.
Last night, it gets really bad and i am able to get into the phone once. After that it freezes always when you initially power on, you see the boot splash, but no numbers in the bottom left, no moving forward.
AND NOW when i power on, the screen stays black, and it just vibrates and will not stop at all unless i remove battery. In fact, as soon as i pop the battery in, it starts doing this.
WTF!!!!!!!!!!!!!!!!!!!!!!!!!!!!

anybody

Try doing a HARD RESET.
If that does not help it means you have a damaged HD2 motherboard, try contacting T-Mobile or HTC for a replacement.
I'm 100% sure it is a heat problem. I do have the same problem. With my HD2 disassembled I checked that "freezing" the motherboard make my phone boot without a problem... and it worked properly as long as it stayed cool.
I'm trying to replace the motherboard by myself as I do not live within the USA...
Hope it helps.

Same exact problem here, although it happens less often for me. How do we keep the motherboard "cool" so it won't happen? or is this a sign of motherboard going bad soon and it'll be replaced sooner or later??

I think it is a sign of a dying phone... or at least a dying motherboard.
Maybe (just a theory) these are signs of a "cold joint" similar to what happens to the Xbox 360... and the way to fix it is to "reflow" the motherboard... but we need a more technical point of view on this one...

Thanks for the replies. I have tried the hard reset, but it just vibrates with the screen off still, no success in any attempts to do anything. I guess i will have to contact htc since i did not purchase the phone from tmobile.
I did notice before this happened that the phone was getting hot after even a few minutes of use. So i have to assume it is a damaged motherboard or whatever it is inside of my precious hd2 that makes it bring me joy.
Now i am joyless and sad.
Back to the old 2g iphone

[Q] Constant black screen from boot, but still responsive

My ROM is NexusHD2-ICS-4.0.3-CM9 V1.1
The last thing I did was watch a video on YouTube (Application). I then got a black screen the next time I tried to unlock it, this has happened a few times with this ROM so I normally just soft reset it by taking out the battery.
However this time I did it again and my phone turned on, but was constantly black. It vibrated as if it was turning on but did not do any boot logo. Tried booting it into the tri-color screen and nothing still.
I have realised though that it is still booting up, and working like normally, but the screen is just black, it is a lighter black as if it's responding if I press a button. I managed to unlock my phone by doing my pattern, and I can hold the home button and feel a vibration, so I know it has booted into Android.
I'm just really not sure what to do, I've looked all over the forums and found one similar problem but no solution. I think I can get into the tri-color screen if I hold down vol down but it won't show the screen, I just know it is in the screen as I see the light is constantly a light black as if it is constantly on.
Shall I try Task29 or does anyone have any idea what I should do?
Edit*
I can now run AndroidScreenCast and operate my phone from my PC. I can control my phone as if i was normally, but the screen is just black. Like I said it turns onto a light black when anything happens but hat's it. Is it just my screen afterall? (It has been cracked for over a year now but no problems upto now..)

My guess is that you accidently disconnected the output cable from phone to display.
This should be the issue since there seems to be no screen but interactive elements.

Any idea if I can do anything about that myself?

Hmm the cable is right under the hardware buttons.
You can try pressing around them to have a chance of getting it back (no guarantee and if you break your display its not my fault).
If you are experienced enough you could remove the LCD but I don't know anything about that.

yes, you could be the ribbon cable connector to the motherboard, you must fully remove the display and see if the latch on the cable connector is closed.
Also check if the cable is securely attached to verify you see two small ends' near the copper plug is attached to the plastic connector on the motherboard.
good luck

Screen or GPU screwup

Hey guys, I'm making this thread basicly just to vent I sent my DHD in for repairs in late march because the volume rocker had come loose and it would be fixed under warranty, no biggie the phone did take a couple of weeks to get fixed but I knew that when I sent it in, now when I got it back I immediately tried to start it at my dealer but the phone wouldn't start I thought Oh well prob didn't have allot of battery when I put it in. So I came home but in the charger and turned it on, to my surprise they had tried to update my fw it failed and I was left with a phone that only had access to HBOOT, since it was fully functional when I put it in for the repairs (Stock rom S-ON) I took it right back and they tried to flash it at the dealer to no avail, I once again had to be without my phone for a few weeks, now this thursday I finally got word that my phone was ready to pick up *YAY* (they changed the mainboard) I was quite happy since I had been given an old desire bravo as a loaner while mine was being repaired thinking oh happy happy joyjoy these last two days having my phone back.
Now this evening when I went to look at the clock on my phone I saw right away some strange artifacts on the screen like green is bleeding through? I tried to restart right away and when the phone shows the htc logo the first time around it's clear no artifacts perfect white and green, and then as soon as it enters the OS the ****ups start to appear, what could be causing this?
I'm sorry for this wall of text but my patience for htc is wearing quite thin now and I'm not thinking I will ever buy another handset from them again

same game on my Transformer TF101

I have no idea why imageshack has the seccond picture upside down but you get the picture

Sounds like they botched the repair job.

theres either a break or a short in the displays ribbon cable

dude, if you've sent your phone twice, you should tell them to give your money back and you have right to do so. Once you do that, get yourself a dual or a quad core

Using a broken phone, a life story

Hello, I've been best friends with my Atrix since a little over a year now. We have had many experiences together and our relationship has bloomed a lot with time. I confess I haven't completely looked after my phone, I'm a little clumsy, specially if I don't get to sleep enogh. So almost a month ago, after getting up very early, I was reading a notification when my phone fell. I tried to grab it but I pushed it even more. It went straight to a cornered tile on my bathroom. This was the result:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And trust me, it's much worst in person than you can see there. Surprisingly enough the touchscreen works just as fine as it always did, even the notification area works fine (the top of the screen has been the more affected area), although I can't use the front camera anymore because there's a big scratch on top of it. Also something happened to the headphone jack because I can't use it anymore. Regardless of all this, the phone itself keeps working like a charm. I have been unemployed for a couple of months now, have a couple of bad debts so I don't have any money to fix it for the time being, so I have no choice but to use it like this.
But I have two weird errors, which has caused me to write this. The first one is related to the proximity sensor. Everytime I answer a call, the screen turns off as it should, but after the call end the screen doesn't come back on and there's no way for me to turn it, so I have to pull the battery and reset it. I tried to mark the option for the screen not to turn off when I pick a call but it keeps doing it regardless, so I suppose what I should do is to try to take the phone apart and see what's happening on the inside.
This pulling of the battery has led me to the discovery of the second error which I think it's the most interesting: 1 out of maybe 20 times that I do that, for whatever reason, a random app gets uninstalled from my phone. The first time it happened I blamed the app (growlr was the first), but then I saw it happened to Twitter, then to Google Plus, then to Script Manager. And it's not like it gets deleted completely, if I go to the app manager I can see it on the list but not with the regular name (ie: com.twitter.whatever instead of just Twitter). I'm using Neutrino but I'm not sure if I could blame the system, I think it's caused from the battery pulling in the same way turning off a computer by force can produce errors on the file system.
So has any of you come across problems like these before? Do you have any suggestions?

Black screen?

My phone was working fine, picked it up just now to check calls etc screen wouldn't come on. Hit the power button the lights come on a notifaction came through and started flashing but still the screen wouldn't come on. Pulled the battery and restarted the screen lit up like the static on an old TV then went of again.
Whats wrong?

Mine freezes up sometimes, screen won't come on, go to pull the battery too
It's possible something got corrupted when you pulled the battery - try clearing caches from recovery

Buggy ROM, are you running Lollipop?
There are many bugs in LP at the minute, if you upgraded from KK it's advised to perform a factory reset to get rid of a good number of bugs, KK leaves behind rubbish files that cause problems
I factory reset mine but occasionally get the black screen problem - known as SOD or Sleep of Death - phone goes to sleep, doesn't wake back up

I had same problem... sometimes it look like the light is very low... suddenly the screen went dead.... samsung replaced the screen.

Yes I am running lollipop I already had done a factory reset and cleared the cache. Happened twice again today. I got this

When I pulled the battery, tried a couple of times and it eventually worked. I may be wrong but I think there is a lose cable connecting the screen.

I'd get it repaired under warranty if you still have it, factory reset should have fixed it if it was a ROM bug, could try flashing a stock ROM again, but I think that's more likely to be a hardware issue

Yep, just came across a massive thread on Android Central about this issue, seems to be very common.

Any update on this, I think it might of been the case causing issue. I had one of them cheap plastic cases on it, it was so tight I had issues pressing the buttons, and when I took it off back cover and everything pulled of. Anyway I replaced it with an S View case and all has been fine. Could it of been the case?

Guess it's possible if it was extremely tight - not sure what's directly under the body of the actual phone, you'll have to give it a while and see if it happens again
Hopefully not
