[Q] Boot Problems

Hey guys, wondering if this great site can help me out. Just got a phone off of eBay (White HTC Evo 4G) However when I plug the phone into charger(s) it doesn't light up, display any LEDs whatsoever. furthermore if I try to power on the device it does the usual display of the HTC EVO 4G Logo on the whitebackground but then the screen quickly shuts off.
I then try the power+vol up key to access recovery menu. It will finally display the menu BUT THEN quickly the screen shuts off.
I then try hard reset, holding power button + vol down button. Same thing, menu pops up, as soon as it does the screen shuts off.
Connecting via USB cable of course windows does not detect it, it wont even boot up for that matter period via this method. lol. Any suggestions?
Send it back .... fast.

[Q] Need help plz phone died

Hi there
I updated my phone to jellybean yesterday i am with tmobile uk , the phone worked fine after this everything seemed to install ok.
until a hour ago, i got a phone call answered it, then hung up, i put my phone in my pocket, next time i took it out the phone was locked on the boot page the white screen with htc logo on, i tried to power it off and the the 3 buttons on the bottom of phone started to flash white for 10 seconds then phone swithed off. the phone wont turn back on, it wont charge, tried usb to computer no lights nothing. the phone was fully charged when it switched off. my phones a standard one never touched bootloader etc
i spoke to htc they think its software problem, they say when i downloaded jellybean i used 3g not wifi (my fault) this could have caused the problem as there could of been a drop in signal they tell me.
the problem i have they want 210 pound to fix and they say its not under warranty as i have had the screen replaced, but not by htc voiding the warranty.
Can anyone here give me some advice or help to fix my phone please.
thanks

Can you enter the bootloader by holding the power button and the volume - button together, keep them pressed until it enters the bootloader.

[Q] HTC One X. Stuck in a restart loop

I had my phone sitting on my desk, pressed the power button to check the time, and set it on the desk again. Suddenly, I felt it start vibrating over and over and over, and when I pick it up to check what's going on, I see it's stuck on a restart loop. The phone turns on, the "HTC Quietly Brilliant" logo appears for about two seconds, and it turns off, again and again. The same thing happens with the phone connected to a charger, and if I press power+vol down when it's turning on, I get to the bootloader screen, and it shuts down again (can't scroll through the options using the vol keys). The phone is running on the stock ROM, and I did the OTA update like three months ago. Any thoughts on what's going on would be greatly appreciated.

your power button is stuck in press position try press it to release it
The button seems to be fine. It doesn't feel stuck, and has a normal clicky sound. I tapped on it, and wiggled it a bit, and the same thing keeps happening.

yes the button it self is ok but the back side is stuck try hit the phone near to power button with the hand to release it
Either the button is stuck or your power flex cable has malfunctioned. Power Flex Cable can be replaced and should solve this problem - see the below thread I made some time ago regarding this:

My issue was water damage but would cover any damage to the power flex cable.

Help my M8 went blank all of a sudden

I used my phone two times after a full charge and then pulled it from my pocket it was non responsive.
I have Android Revolution 32 installed and the latest twrp. The phone is unresponsive and does not charge. The charging LED lights for 1-2 seconds then turns off when plugged in. This has been going on for 3 days now.
I have tried volume up + volume down+ power and get the power indicator to turn on then immediately turn off. I have also tried volume up + power and volume down + power with no response from the device. I have had the device for 6 months and it has worked perfectly untiln this.
