[Q] Black screen but still has sound and still usable ? - HTC One X

Hello All
I have a HTC one X. I installed Cyanogenmod on it a few days ago and it was running pretty fine. Until last night my phone started to freeze a few times. So I reflashed the rom ect and it fixed it.
This morning I was messing around on this phone and it froze yet again so I held down the power button to reboot the phone.
Now the phone itself turns on but its shows a black screen. I can unlock, I can hear sounds, I can even receive phone calls and text messages and play around on the phone (but cant see anything)
I have tried plugging it in to my pc and going in to the SD card but in order to do that on cyanogenmod I will have to tun usb storage on, on the phone which i cant seem to do.
I am wondering whats going on with my phone and are there any ways to fix it or is this the end of it ?
Regards
Gentle

[Q] Odd problem, phone won't boot.

Volume button on my HD was playing up for the last few days so I decided to reset the phone today via the power button just incase it might help, since then it hasn't started up again, I get 3 buzzes after I've removed and replaced the battery and then the amber light flashes constantly.
I was running CM7 for a while but went back to stock as I missed the sense UI so I should be on the most recent update.
It's a pain because I'm on holiday so have no access to my PC, I have access to Macs but I'm not sure there is even an HTC sync style application for that system.
Many thanks in advance for any help.
Ok, phone was left off for ~24 hours, battery totally flat, I switched it on and at screen came alive, unfortunately the sim hadn't been inserted properly and phone demanded I reset it, when I did back on the fritz, will give it another 20 minutes or so, hopefully will be back to the same state where I can start it again and go from there, were there any bad 2.3 updates that I possibly installed when I went back to stock?

[Q] Desire froze, after reboot blank screen, vibrations

Hello, i bought an older desire, installed cyanogenmod 7 on it and all was running ok for ~4 days.
2 hours ago i left the phone on the table, battery was around 70%, when i came back screen was blank and i was unable to turn it on or restart it. I pulled out the battery and then inserted it back, after turning on the screen is blank and the phone permanently vibrates.
i have tried common key combinations mentioned on forums (vol - + power, back + power, vol - + power + home) with no change, the screen remains blank and the phone constantly vibrates.
i have tried to connect it to pc and to boot into recovery blindly, adb / fastboot doesnt list it after any of the key combinations, lsusb also doesnt list it, it only drains some power from usb.
I would like to know what happened, i would have understood if something like that had happened while i was flashing it / rebooting it after flashing, but it ran just fine for over 4 days. Now i have a nice usb powered vibrator :]
Would anyone care to help me with my issue? It doesnt seem to be covered anywhere on the forums. I am an android newbie but i can test probably any idea you may give me. Many thanks.
Very strange...
Try to remove the SD and the SIM to discard them as the problem.
Good luck
i have already tried that. and i have tried all combinations of sim / no sim, sd / no sd.
no effect.
i have got the same problem!!!
i've tried to root my desire following the instructions from internet, maybe i did something wrong. after i running bootloader from hdbootscreen it run in cmd window from pc the moment later it automatic shutdown the screen to black but the phone system was seem still work. ive tried to remove battery SIM SD card and reboot by combined button like instructions but nothing above screen, just stayed black screen, but my phone vibrated when i try to push power on
i hope anyone can helps us, ive just bought it 2day ago.
thank in advancej
Hey mate
I gave my old desire phone to my dad to use and I got that problem. According to him, he turned the phone off to charge and when he turned it on it just constantly vibrated.
Kinda puzzled me at first, I pulled the battery, sim and SD out but didn't fix it. Found my other genuine spare battery for it and put it in, I let it charged for a bit and turned it on.
Phone's now working with the other battery, I think I eliminated the problem but I'll have to hear back from my dad to see if he encounters the problem again.
Hope that helps you mate

[Q] Help? Neither of these work?

I'm sure some of you know of me and my recent phone problems of it having a random bootloop every few times I press the Bad Power Button I've had. I found a solution for a while which consisted of 2 apps, One that's a widget that allows me to lock my phone and another which is an app that allows the sensors on my phone to work continuously so that If something moves in front of it it will turn on. Now One day as I sat down i heard a faint vibration and finally noticed my phone fell into a bootloop once again.. I did the normal and tried to make it to Recovery Mode and then Wipe the Cache..After many many tries... More than Normal.. I finally got into Recovery Mode and wiped my Cache..But even after doing so it fell into the bootloop once again shortly after I finished wiping cache..Didn't even get a chance to hit "Reboot Phone". Did the same thing a few more times before giving up and resorting on trying to go into Download mode.. I can't even get into Download mode since When I hold down the VOL + VOL - Buttons and plug in the USB it continues to vibrate.. I have No clue what To do Next. I WOULD love to just return to T-Mobile and receive a replacement But I fear that they might find it is rooted and charge me for the full price of the phone.. Also I'd love to have transfer all of my messages and Other Personal Data off my SD card to my laptop.. Help Please? If there is a way Can i take everything off my SD without having to completely get it out of this bootloop ?

[Q] Has my Samsung GS2X become bricked?

Started acting up last week when I noticed it restarted on it's own, but didn't fire back up right away. Instead it went into a reboot cycle for almost an hour (doesn't make it passed the Samsung splash screen). Then it just fixed itself and I was able to access everything as normal.
Once it was going again, I backed up all my info and did a factory reset and proceeded to re-load Jellybean (4.0.2?). Although Kies said I was already up-to-date and didn't do anything.
Anyway, worked fine for a week until yesterday when it went into the continuous reboot cycle, and never fully turned on again.
I have pictures and vids I would like to somehow recover (on phone and not on SD card), but I have no idea how to get the phone to start up. I have removed my SIM and memory card to see if that did anything. Also have done numerous hard resets (pull the battery and lock + vol down combo). It basically just kills the battery as it cycle reboots. Every few minutes, it will fire up again but still doesn't make it past the Samsung splash page. And when the phone is charging, it just doesn't turn on in general and just intermittently vibrates to try to start-up.
Dunno how I would even be able to flash the ROM (newb at this) since the phone doesn't stay on long enough to access the BIOS of the phone. Does this seem like a software or hardware issue? I bought this phone 2nd hand off Craigs about 2 years ago, so no idea if it was a refurb.
Has anyone experienced this and can direct me to somewhere so I can fix it? Or is it a goner and I should just move on to another phone? Any help would be greatly appreciated.
Its likely a stuck power button. Search here or Google for treatments.
Sent from my Moto X cellular telephone...
it sounds like a problem I had once
Galaxy S2 Wont boot anymore
one option was to disassemble teh phone and check the power button , someone recommended I use an eraser to tap the power button and see if that would unlodge it and to my relief that worked. You might want to try that first

[Q] Screen Won't Turn On; Everything Else Functions Properly

I am/was having an interesting problem with my SPH-L710. I was recently at the gym listening to music on my phone, and it was functioning normally. I took my phone out of my pocket and pushed the power button, but the screen wouldn't turn on. The music was still playing, so I knew that my phone didn't just freeze. There was no immediate cause for my phone to stop working (ie I didn't drop it or get it wet at the gym), although I've dropped it several times before today without incident.
I took the battery out of the phone for a few minutes and restarted my phone. The phone turned on normally except the screen wouldn't turn on. I called myself from my landline and used the normal gesture to answer my phone and confirmed that I'm able to receive phone calls and that touch controls are working. I also tried booting my phone into both the recovery and ODIN download screens. I'm not sure if I successfully booted into those modes, but I do know that my screen didn't turn on when I tried to boot into those modes.
I took the SD card out of my phone and activated my backup phone through the Sprint website. I tried resetting my SPH-L710 after deactivating it, and the screen was functioning again. I reactivated my SPH-L710, and now it appears to be functioning normally. I have no idea whether taking the SD card out or deactivating my phone actually solved my problem or if it was just coincidence.
My ROM is MD4 with root. I have Team Win Recovery Project v2.5.0.0. My phone has been nagging me to install 4.3 for a few months now, but I haven't gotten around to researching updated ROMs yet.
My phone now appears to be functioning normally. Has anybody experienced anything like this before?
