[Q] Desire won't boot up

two days after updating my unrooted desire to 2.1 over the air(ota), it started giving me problems.
First it started by reducing the ringer volume on its own untill its on vibrate, then it would go into car mode.
I restarted the phone, then that stopped, but 3 buttons(menu, search and action key) stopped working.
I did factory reset which didn't help and when I go to the web, the browser would turn the wrong way(landscape).
Now the phone just won't boot up, it gets stuck on the htc logo screen.
I have read some suggestions here, but nothing works.
I tried recovery, but it still get stuck on the htc logo.
Any help will be very appreciated.

[Q] [Solved] Stuck at HTC One Screen

Got a HTC One X a while back and decided to keep it stock as long as I dont find a stable recovery. So my HOX was completely stock. Had no issuses with it for the time I have used it which should be around 15days. I did experience some random reboots. Overheating was a problem too.
Last night was using gameboid to play while watching soccer. After match, I tried to use inbuilt browser but it could not be launched. Everytime I started it, a menu opened with sending a report or not. Then tried google play store to download another browser, but that failed too. Even apps did not upadate. got a error. Dont remember exactly but most probably that was error 492.
Then i decided to reboot. After the HTC quietly brilliant screen, came the HTC ONE screen with some sound, and then hung up there. Tried a hard reboot but same thing happened but this time onwards sound vanished.
So what should I do?
Thought of going to bootloader and then factory reset but I have some important data in HOX and then doing factory reset might not solve the problem.
What should I do?
Just to tell you, Now when I went to bootloader and turned off and back on while plugged to laptop, its still on the same screen but this time its charging.
It does not charge while turned off.
Again,
Im unrooted - completely stock and not unlocked via htcdev.
Edit: The phone is charging now with the power adapter.
Edit2: Just did a factory reset via bootloader , back to normal now.
When still completely on stock and haven`t done anything.
I would say return it..
There would be answers and suggestions but why void warranty.
while my phone hangs up at htc one screen, is there any way the data can be restored? Im assuming running ruu erases everything since its virtual sd card.

Cant turn the screen on and stuck after screen off

My One X works properly for close to 2 years but last 2 weeks my phone start to have strange problem. It will randomly reboot and stuck at boot up or sometimes after screen off I cant wake it until I hard reset it by holding power button. And a lot of time it will just stuck during boot up with HTC logo and cant go into OS. I tried to return to stock by flashing nandroid backup, even reflash the hboot but the problem still there. I tried connect the phone with my pc and I can hear the usb unplug sound from pc after the screen off for some time. However, it is not stuck in sleep everytime, but often. Anyone have any idea what was wrong?

[Q] Sudden Restarts every 5 seconds on my Note 2 (n7100)

Hello everybody,
I really need your help. A few days ago, i just watched a video, and suddenly my note 2 restarted into a bootloop (MXPlayer). It is rooted and owns the last official stock rom with CWM touch 6.0.4.3 or smth. i took the battery out, plugged it in again - nothing changed. I tried to enter into the download mode, (Vol+Power+home) but as he asked me to press the volume button - no reaction at all! so i werent able to enter into odin mode anymore. (normally it solved such problems for me). I sent it to samsung, they said, that my garantee is void (rooted). i bought myself a USB jig. with his help i were finally able to enter download mode again but - my god - it crashes every 5 seconds so it wont be possible to flash my device. is there any clue (maybe via PC or smth) to force my phone not to restart, or to force to do a full wipe? (including that broken memory or what ever there doesnt work anymore) i would be happy for some advice. thanks in advance! i hope my phone is not fullbricked, because i were able to get into download mode - just that restarts destroy me everything.
anybody can help me? i am upset.
Maybe stuck power button

[Q] HTC one X boot issue

Hello,
In the last few months i have had some minor issues with my phone. In May or in June I have tried to root my phone. It was my first device I wanted to root, so I decided to use Kingo Android root. It didn't work. I installed HTC universal toolkit ( or how was it called ) from XDA forums to my computer. With its help I unlocked the bootloader, installed the TWRP and rooted the phone with Kingo. Everything worked OK, the only problem was that TWRP didn't respond to touch input. I didn't solve it at the time because it wasn't urgent. A month ago I installed few root apps from Google Play, but I didnt experience any issues. Today I was browsing the internet and suddenly I saw a HTC logo and the screen came grey. I waited for a minute and then force turned the phone off. It didn't want to start again. I booted into bootloader. It showed few errors, but was successful to boot. I wanted to open recovery, but it opened the bootloader menu again. Factory reset option didn't work too. I turned the phone off and then turned it on again, but it was stuck in infinite startup loop. Also the HTC logo was broken, there were strange colourful squares around it.
How can I repair my phone? I know that it isn't totally bricked, but this looks really bad. At least I would like to save my data and I will buy a new phone.
Thank You very much for Your help.
