[Q] Phone doesn't turn on immediately and problems come after - Desire HD Q&A, Help & Troubleshooting

Hi,
My phone won't turn on when I pressed the power button, after leaving it awhile, it lights up and it shows the white screen with 'HTC' logo, then it vibrates non-stop for 5-6 minutes, then the vibration stops. After leaving it awhile, it eventually boots up to the phone (sim unlock) and can b used normally. The thing is, rebooting the phone will also repeat the problem mentioned above. Nothing for some time then white screen comes out with non-stop vibration. Even if i boot to recovery, it will still be the same.
Any ideas to fix this?
Thx in advance:fingers-crossed:

Sounds like a hardware problem...clear cache and whatever in recovery....maybe dalvic cache isnt sticking after reboot(if your rooted) but other than that not sure

Backlight Won't Switch Off.

I dropped my XDA Orbit the other day, and ever since the backlight and the blue scroller constantly light up, and whenever the phone is restarted the Bootloader screen shows up, and the only way to get the phone to boot is by using the hard reset buttons (the phone then boots up normally and all data is still there). Do you think this is a warranty job? Or is there any way to fix this?

[Q] NO WAY! This is not possible?

I was talking on the phone and BOOM it resets.
It started reloading and can't! WTF!? It just gets caught. The Samsung logo comes up and then the darkside boot animation (been running this rom for a few weeks). Then it blacks out and does these intermittent vibrations like it's trying to boot but just stays black.
When I take out the battery and put it back in, it attempts to load itself without me touching any buttons. After the boot animation it goes black and does a single vibration that pulses every other second.
I've changed the battery several times, plugged in, unplugged, everything I try can't stop this.
I attempted to get it into recovery. After I get it there, it resets within seconds and puts me back to the same place. There is no way to get into download mode as it goes into this weird loop as soon as I plug the phone into USB.
Ever heard of this? What do I do?
Your explanation sounds like a hardware issue. your power button is being pressed and held without you doing it.
1- is the phone in a case? take the case off.
2 - if no case, did you get the phone wet? somehow the power button connection is being activated.
3 - power button is stuck.
Possible solution - remove battery then press and release the power button several times.
Let me know if that solved the issue.

[Q] Screen flashes after Samsung logo, screen black, vibrates every 2 seconds

My phone just started acting up really weird. Whenever I would graze the power button (not even when I push it in all the way) the screen would lock and sometimes immediately turn back on. Some times the power menu would come up. Other times it would just restart and go into this weird loop where the screen would be black, the phone vibrates, and the LED just flashes. Does anyone know what I should do about this? I was using CM9, but this happened pretty randomly so I don't think its a software issue.

Try flashing a different ROM. There may a bug or something on that ROM that could be doing that.

You just got a malfunction power button. It happens a lot. You need to call samsung/tmobile for warranty service.

[Q] Bricked help/ideas

In short, the phone is stuck in a bootloop unlike any I've read about before. All on its own, it constantly makes the bootup vibration pattern but it does not boot up. The screen does not light up, it is completely black (backlight is off as well). It is sitting on my desk doing the vibrate patter (bzzz-bz). Then 40 seconds later, again, (bzzz-bz).
If I could see the screen, I imagine it is going past the 1st Asus Logo screen, then trying to load the OS (2nd Asus Logo), but crashing and restarting.
This happened after I flashed fastboot (droidboot), recovery, and boot. All flashed successfully, so I went into Recovery and started to "wipe cache". It was taking too long so I thought it froze and forced a restart. After that, I never saw the screen light up again.
Any ideas as to what is going on? The phone has no damage (at least physically ).
Yes, wiping cache takes a long time you have to wait it out, forcing reboot before it finishes will result in bootlooped, that is covered in many many threads, you will need to reflash entire Rom from bootloader.
Problem is, I cannot get into bootloader. Its still doing the vibrate cycle I described, it's been 8 hours already.
Try holding the power button and volume up toll you get 2 vibrates then release power, if that does not help it sounds like your power button is stuck in depressed mode
Stuck in depressed mode? But I am able to press it, and I hear it click, and click back up. The "spring" seems to be working fine.

Black Screen on some Reboots...

I am wondering if anyone has experienced the same issue that happens to my phone every few weeks. I don't usually reboot my phone, but sometimes I do. Occasionally, when the phone starts, the screen is completely black. If I shine a flashlight on it, I can sometimes faintly see the screen. The only thing that can resolve it is holding down the power button for 10 seconds so it restarts.
Sometimes when it happens, if I'm in the car etc, I can't tell if the phone is on or off, so it's a bit of a headache.
I've completely reset my phone and flashed an Android 10 Image a few months ago, but it still occurs. ( This was a full factory reset with clearing cache etc in recovery ). I've never rooted the phone, but have always had bootloader unlocked.
Anyone else ever experience this?

I'm still on Android 9 and occasionally this happens to me too. I rarely reboot so I don't notice it that much but it does happen. If I hold the power button down I can feel the vibrate feedback for the power menu presumably. I've never tried to troubleshoot it investigate because it happens too infrequently for me
