[Q] device unlock issues and freezes - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

I've recently updated my hd2 from android to wp7, and when I lock the screen, after a minute, I try to light up the screen and I can't, then the device reboots after a couple of minutes. Also while i am using it i have freezes and the device automatically reboots. Its annoying, i already tried with 3 different roms and its all the same. I would appreciate some help.
Thanks.

your problem is SDcard....

Maybe I have found one of the reasons that causes the boot up freezes

I'm suffering from the freezing problem and even though I have tried several custom and official ROMS, the problem still persists.
After reading a lot of threads, I started experimenting myself with T-mobile HD2.
What I found is that when I soft reset my device although I have disabled HTC Sense the freeze that occurs in the splash screen never appears again (up to now I have tried over 15 times, without any freezes!!!!)
Something else I noticed, is that when the freeze occurs while I am in normal operation (HTC Sense is active and I'm running an application) some times I have and some I do not have the boot up freeze. Sometimes it refuses to start and I have to take out the battery several times before it starts up again. If together with the battery I take out the SIM card too, I have no boot up freeze (I didn't have the chance to check it many times).
Please, do your own tests too, and write down your observations.
Most of the time if you get a startup freeze it's because of something on your SD card, so I'm not quite sure why yours is intermittent like that...but, it IS WinMo afterall.
Before I figure out about Sense, I had freezes even without SD card.

Frozen phone when trying to wake up from standby

it happens to me very frequently on my galaxy s4 value edition i9515. That sometimes when my phone is locked and i m trying to unlock it, it freezes and it doesnt responds the screen stays black, then i need to press the power button for some seconds continuously to restart. this problem has happened with android 4.4 and now with 5.0.1 stock android. i did once tried to install custom roms and my knox is out of warranty.
this problem happens once every few days and extremely random! i cannot get any conclusion on what causes it and i already installed the original rom many times and some times with very few apps installed, although this doesnt make a difference i tried not touching anything as well...
does this happens to other users as well? or did anyone had the same problem and found the solution? or any advice?
i reallly like this phone and i dont want to buy another one just because of this, or even to move away from android because its just dont working!
Imagine i cant trust my alarm anymore, it has happed not to ring and to loose apointment............
thanks in advance

HTC 10 (verizon) reboots randomly.

This may seem like a noob thread (which it probs is) but my issue is probably rare in htc 10 phones. You see.. my htc 10 just randomly decides to reboot from time to time. I've noticed some pattern to it but it still does not help. The reboots occur randomly. Some days, no reboot at all. Other days, it reboots so many times. Reboots more noticeably while watching videos (I got the phone knowing this problem). So, a logical person might say, "Hey, why don't you reset to factory settings/why don't you flash stock ruu/use htc repair tool or sync manager." To which, I reply, "I have done literally everything I can except getting it s-off and flashing custom rom on it. And the best part? when I select repair on htc sync manager, it says, "No software available for your device""
It may be a hardware issue. Most people say that it could be related to battery. If it were related to battery, the phone would just completely shut down and restart. However, in my case, the phone hangs or freezes for about 10 seconds and is unresponsive till it finally shuts down and reboots. I've put in safe mode as well but still no luck.
I've completely gone into zen mode now. I don't watch videos anymore xD
Help would be GREATLY appreciated. Thanks.

Can't turn off

Hi there!!
Three days ago I bought a used xrn 7. I realized I had a ROM installed but I still bought it although I figured it might have an account ... And so it was.Thanks to my experience, I was able to unlock it, and I installed the "official" ROM, but these days I realized that there are some errors like I can't turn off the device. When I press the button to turn off it only vibrates but the menu does not appear to turn it off and if I keep it pressed longer the phone restarts. Also sometimes the phone freezes and restarts itself. Could someone help me and tell me if it is the ROM? if so... What ROM do you recommend? Thanks for your help. It should be noted that I am from Mexico.
