Hello!
I have strange problem with my HTC HD2.
I doesn't power on without charger. It only powers on with charger plugged in to PC or wall and when soft reset button (under battery cover) is pressed. So it doesn't power on with power key.
When phone is powered on it shows only black screen with screen lights and key lights turned on. I can hear the boot sound from HD2's speaker so I think it boots into Windows Mobile correctly.
When plugged to PC and phone powered on, PC can recognize it. I have tried flashing newest ROM from HTC website but no change. Still black screen whole time.
Problem came after I installed new touch screen digitizer+LCD assembly. LCD ribbon looks OK and its plugged to motherboard correctly.
Could this be software issue?
I would be very happy if someone could help me with this strange problem.

It's not software, sounds like your digitizer to motherboard is messed up somehow. Worst case is dissemble and try again.

I have assembled and disassembled it again and again few times with official htc hd2 videos but no change.
Could this be radio issue?
sounds to me like the "front" face of the phone isn't properly connected with the motherboard and rest of the stuff.
FACT 1: the front power (or end call) button isn't working
FACT 2: the screen is blank, probably not powering on and/or receiving a data signal
FACT 3: the device appears to boot for all other intents and purposes
disassemble...reassemble...pay attention to the button strip and the LCD ribbons...maybe you might see something wrong.
Also, no radio or ROM would cause this issue, I don't see how this could possibly be software in any respect.
Disassembled and assembled again but still no luck. I contacted to ebay seller who sold lcd for me. He said that he will send me new lcd + digitizer assembly.
So I was trying to replace a friends digitizer screen and in the process of doing so I ended up ripping the power button ribbon cable. When I plug the phone in with the battery in the orange light signifying it's charging goes one which I assume is somewhat of a good sign. But I still have the problem of the power button not working. Is there anyway I can turn this phone on with the power button?

"Turn this phone on with the power button"
lol yeah sure just press it
Assuming that was a typo and you cannot turn it on; try to open adb then do "adb reboot"
Also I heard that when plugged in, the phone will boot into recovery if you are using CWM Touch (we have it on the dev section )
Hope I helped.
This morning my nexus 4 (Android 5.0.1) having some issues about crash of google applications. I decided to do factory reset so i went to settings and apply factory reset, it was showing power turn off then after it has not been started again. I tried to plug charger and everything but nothing is worked out.
Now, when i plug my nexus to wall USB charger or laptop USB charger then i can not able to see any charging icon. I tried to hold down power + volume down keys but nothing happen. But when i hold power+ volume down keys and plug it to any charger it shows red notification light which blinks for 10 seconds when i leave power+ volume down keys red notification light went off.
Tried below solutions nothing worked for me till now. Anybody please save my phone, it does not have warranty.
1) Put it charging more than 2 hours.
2) Checked this solution too, but no success. http://www.reddit.com/r/nexus4/comments/2cwijm/nexus_4_wont_turn_on_blinking_red_light_not_a/
3) Checked this Deep Hibernate solution
http://www.guplum.com/nexus-4-not-charging-and-turning-on-and-died-suddenly-hibernation-issue/
4) Also tried x-da developers solution

Please any body help me. I am really frustrated.
Hi lumia owners
I had that issue yesterday when the phone just turned off directly and does not want to start by pressing power button.
During the issue i was using viber and messanger (fb) and vivid browser.
Phone is running the latest insider previw "feuture 2"
And i am sure the battery was ~60 % while the charger is plugged in.
The heat was not too high nor low.
I did some research but all the tricks didnt help.
Maybe i miss something.
Well, the phone only vibrate once i plugged in the cable, pressing the power button -or vol down + power button- (while plugged) vibrate after ~10 sec but nothing , while doing the same process without the cable make. no vibrate or anything.
If any one know how to fix this its gonna be a big help to all, thnx in advance
put phone on charger some time (30- 60 minutes) and try volume minus + power trick... if battery level too low, phone wont boot
if nothing helps, use Windows Device Recovery Tool.
Hiya!
The phone seems working properly except the LCD screen is black.
When I press the volume button I hear the beep noise and can receive calls.
If I put the USB cable windows does not recognize it. I see a device named 3 cdc-acm 4 cdc-ncm.
I have another S4 works great with the same PC so it is not a driver issue.
Can I fix that phone? DO you think it is hardware or software issue?
thanks
Volume down + home button + power button does not work
