Black screen after updating - Moto G Q&A, Help & Troubleshooting

Hello!
I have my Moto G 1st gen next to me and it's screen is completely black.
I've bricked my phone ( cannot mount /data ), so i tried few firmwares to stock it and get work.
When I made my phone working I went through start up like picking language, wi-fi etc. then checked for updates, because moto g was 4.4.2.
Phone found update to 4.4.4 and wanted to restart for update so i let him restart. It was updating, there was like 3/4 update when screen of my phone gone black.
I thought it's just screensaver so i left it like that, but when i wanted to unlock it or boot it up it was just black.
Just like now, but when i plug phone to PC using USB cable i hear that windows sound of plugging in.
I cannot boot up to bootloader and when i'm holding power button for like 15-30 second i can hear plugging out sound and after few seconds plugging in sound.
I was checking adb devices and fastboot devices, no devices for both.
And there's not boot screen, there's only black screen, i cannot see anything on screen.
I tried using flashlight into screen to check if it's not just that bug with brightness bar, that's not working.
Sorry for my english but I'm just a teenager not even from England or any english-speaking country.

Just flashes on startup. Black Screen

I got an HTC One S from a friend who got it from another friend. I don't have any history on the device. He gave it to me to fix because I'm the only Android user he knows and his phone won't start.
If I keep the power button pressed, the capacitive buttons flash exactly 15 times and occasionally the phone vibrates. I don't have a One S so not sure if that indicates that phone was started or shutdown.
Neither fastboot devices not adb devices shows the device. But every once in a while when it vibrates, if the phone is connected to the PC with a USB cable, it beeps - like it's connected. I don't see Android Phone in Device Manager. But I see a MTP USB Device with a yellow exclamation mark. Uninstalling and reinstalling HTC Drivers didn't fix the problem.
I have tried Power+Volume Down key. Shining a torch on it (seemed to work for a few people), keeping it plugged into the mains for 3 days, kept it in the freezer for 2-3 minutes (also seemed to work for one person).
I think when I first got the phone and plugged it into the mains, I saw a red charging light. But I may be mistaken. In any case, there is no light anymore indicating charging. But I don't think that's the problem.
I have no idea whether the device is bricked or not. And if there is any way to fix it. Samsung has Odin which makes any Samsung phone practically unbrickable. I haven't used any HTCs since the G1 so have not been in touch too much with the HTC development. But from reading, it seems that messing around with Romming with S-ON can cause the phone to be bricked. And perhaps that's what my friend or his friend did. Does this sound like that's what could have happened?
Thanks for any pointers.
I dont think the device is bricked. its just a little harder to press the power and volume down when you see the buttons flashing.
just check and do these steps.
connect the mobile to charger and see if the orange light comes and stays on
if the orange light is there, press the power button and keep your finger ready near the volume down button
you should keep the power button pressed and as soon as the orange light disappears you should press the volume down button until you end up in boot loader screen
give this a few tries and see if the device boots up in bootloader

The problem is that I no longer see any light at all when I connect the phone to a charger. It's probably fully charged. Would that show a green light? If so, that's not visible either. I have a feeling that the bootloader has got wiped out or something.
I read in one post that the phone may be stuck in the QHUSB-DLOAD mode.
So I followed the steps in http://unlimited.io/qhsusbdload.htm. But that didn't help. I don't remember the exact statement since I was running an Ubuntu Live CD. But the gist was that it couldn't connect to the phone so presumably it's not stuck in QHUSB-DLOAD mode. Although the site states that it will NOT fix QHSUSB_DLOAD issues encountered by flashing ROMs - which may well be what may have happened.
I understand that running an RUU for the HTC One S may set it back to factory state. But for that I need fastboot to work.

[Completed] [Q] Moto G (U.S Cellular) boot loop. wont charge.

ok so i have a moto g that is fully stock and all my apps were from the playstore and i never noticed any bad lag at all. but one day, out of the blue, i wake up to my phone showing the blue m logo and then a black screen and repeat.
so i tinkered around with it and searched the internet and heres what i found out:
I can get into fastboot mode but cant use any tools except for the barcode tool otherwise the phone just goes back into its boot loop. (yes i selected with the volume up key)
the phone has no power what so ever unless its plugged in. and i dont have to press anything to start the loop, it starts on its own as soon as i plug it in. the led blinks white twice and shows the m logo for about 5 seconds then a black screen and repeats once more then it is black for about 5 minutes then its goes into the loop once more.
i cant flash the stock firmware because when i plug the phone into my computer and put it in fastboot mode, the fastboot menu pops up for a mere seconds then the screen goes black and goes into the loop again.
the phone is not damaged and worked with no problems a few days back. i have been through countless websites!
any ideas?
Hi,
Can you specify if it's a 2013 or 2014 moto X.... And I will have your thread moved to your device Q&A section.
Sounds like a stuck power button to me though.
Thanks!

[Q] MOTO G Power button Stuck

Edit:
Ok so i guess it is not a software issue but a harware issue with the power button. It seems looser than the two volume buttons.
Anyone know how to fix that?
Hey
Sometimes my Moto G randomly restarts in my pocket without me doing anything, i have no idea why it does that but afterwards it still works fine.
Yesterday it did it again yet it didnt normaly restart and now its stuck in a Bootloop and as mentioned in the title i am not able to enter recovery mode to clear cache etc.
Ive let it sit over night to drain the battery so i can restart it in the morning. Still stuck in the loop.
It just shows the blue Motorola logo, then the screen goes black and it shows the logo again. Sometimes it does the boot animation where the logo transforms etc. but it just shuts down and restarts again after that.
I have managed to get a "flat" version of the logo and the charging batter once or twice as i tried to enter recovery but it just shut down and entered the normal bootloop again
the device is not rooted or has a custom rom. its running Stock lollipop 5.0.0/1 (not sure)
It is the german Retail version of the 2013 moto g
any help is appericiated

Is it under warranty?
If so I would send it off to be repaired.
If not take the back off absent unscrew the torx keys and have a look at the button see if it's wedged in.

Moto G XT1032 - Can access Fastboot, but it wouldn't work - Bricked?

Hi. First of all, thanks for taking the time to read this. I know it's a long post, I'm just trying to be as detailed as possible.
I've a Moto G XT-1032 that stopped working a couple days ago. It has the original battery, original software. It didn't came with an original charger, so I have been using a Samsung Galaxy Tab one. The phone is almost two years old.
This is how it all started: It had low battery. When I got home it connected itself to the wi fi, and tons of whatsapp messages came at the same time. It went off.
I thought maybe it had drained the battery. Plugged it in to charge, didn't get the led on, and the battery showed 0% for an instant. Then the phone turned itself on, got the M logo and then the screen went black (like... some sort of backlight is on, but the screen is just black)
I turn it off, and it goes back on. No battery image, straight to the M logo, and then black screen. I tried holding power + vol down keys for more than 120 secs, finger pain is the only I got. It can access fastboot mode, but doesn't matter which option I pick, normal powerup, recovery, factory... I select them and then press vol up, but it just goes to the white screen with the M logo, then black screen.
When I plug the charger, and go to fastboot mode, it doesn't show battery charging. Just says battery low (or battery ok). When I plug it to the computer via the usb cable, and access fastboot, it shows battery charging.
The computer doesn't detect the device at all. First time I plugged it, it tried to install drivers, but failed. I downloaded them from motorola's page.
If I open motorola device manager, it tells me there aren't updates for my phone... So... I guess it's recognizing it? But I still can't see it. Windows only shows me my C and D drives, but not the phone. Tried different usb cables, different usb ports. Nothing changes.
I sent it to a service, they tested the battery and charging port, they said those were fine. But didn't find the problem.
Any ideas? Suggestions?
Thanks in advance!

Android 11 suddenly unable to unlock screen via power button or change volume.

Hi, I started having the strangest issue 2 days ago. Phone model is Samsung Galaxy A50.
I have been unable to unlock my phone once I pressed the lock button or if it went to sleep (screen off).
The only way out of the issue is to restart it by pressing volume down and power for 5 seconds. I put the screen timeout to 10mins (which is the maximum). But no long term solution. Whenever the screen turns dark it stays dark. If a call comes in, the phone vibrates (or ring) but any interaction with the phone is impossible. If I play music, the music continues once the screen is off. The sound can be turned up or down, but it's the only thing that can be done.
While the screen is on, changing the volume via the buttons affects the actual volume of the music, but there is no UI indication that the volume changes, no popup nothing.
So all physical buttons are working correctly.
I have trie "reset parameters", I have tried "reset all data" (backed up everything through Smart Switch). It doesn't change a thing. The phone is reset (still on android 11 though, although I bought it on android 10...) but the issue remains.
Now something very interesting :
Just now, I setup Phone Link for windows 10, so that I am able to see and answer texts and phone calls while at the office. Which works, it sort of defeats the purpose of a "cellular" phone but well...
HOWEVER : while my phone is connected to my desktop through Phone Link. I can lock and unlock at will, change volume and see the UI pop up (via the windows interface or directly on the phone, same behaviour) It's basically fixed. I thought it was fixed for good, so I disconnected my phone from Phone Link. The screen went black as before and there was nothing I could do except reconnect it via Windows 10 (then it immediately starts behaving as usual again...).
My guess is it's definitely software. I just don't understand why a factory reset didn't do the trick...
I wanted to try and reset through the bootloader, but I never managed to effectively get into the bootloader (through volume up and power while the phone is off).
I do not recall making any updates or installing anything just before these symptoms occured. I did install a firmware update that was available after these symptoms started but to no avail
Has anybody seen this before ? Thanks in advance
