fastboot... Help - Fire Q&A, Help & Troubleshooting

I've been charging the tablet for 4 hours. It still has a black screen that says fast boot in small letters. This didn't happen with the other one I purchased.
Does anyone have any advice? I want to give it to my daughter tomorrow!
Help!

If you've not been doing anything with it connected to a computer to install things I think you've accidentally pressed volume down when pressing the power button to turn it on.
If so press the power button until it turns off and then turn it back on with hands away from volume controls.
Hopefully just that

[Q] Flashed Rom. Now touch screen wont respond

I flashed this rom ( Sprint_HTC_One_1.31.651.2_Stock_Rooted ) . Phone booted and touch screen stopped working. I'm in a rough situation because the phone also will not reboot. I've tried holding all buttons, just the power button, the power and volume down button. No resolve. Anyone have any suggestions on how to make this phone reboot (besides waiting for battery to drain lol )so I can try to install another rom and see if touch screen comes back. Thanks
You need the newest firmware it sounds like

I cant do anything with the phone though because its stuck on the lock screen. Cant touch anything and cant get it to reboot
Oh and I accidently posted in the wrong section... wasn't sure if I should just leave it up or delete it
Just ask the dev to move it....hold the power button and volume down then release power after about 7 secs and press it again but keep volume pressed the whole time to get to boot loader then go to recovery from there

that would work great if the phone was off...but the phone is on the lock screen... When I hold the buttons It counts down 3....2.....1 then hangs at 1.. Ive held the buttons for over a minute no dice..... It seems the only way to reboot is through ADB but I cant allow my computer to connect to the phone because of the screen being locked... wish there was another way to reboot this phone without waiting for the battery to die

Hold the power button until the home/recent apps buttons at the bottom stop blinking...if it reboots let go of the power and hold vol down this will get you to the bootloader
If it does not reboot press the power and let it start to reboot and hold vol down
The buttons just continue to blink.. no reboot just stuck at lock screen

If you hold the power button down long enough it will power down or reboot
I held the power button down for over 2 minutes... should I hold it longer? Here's what happens, after holding the power button... on about 5 seconds in a message pops up and says continue holding power button for reboot. I continue to hold it and a count down starts.... goes from 3 to 2 to 1.... the phone just stays at one no matter how long I hold the power button in for

hmmmm never seen that before, try holding power and vol down see if it gets you to bootloader
Yeah tried that... pretty much tried all button combinations for all amounts of length....this is how stumped I am. I've been a member on this site for years and I think this is the first time I ever had to post a question about a phone. I seem to always find an answer but this time I just couldn't I'm baffled as to what can be happening and why this phone wont reset.
Yeah I mentioned that in an earlier post. I cant adb because I cant unlock the phone to allow the computer to be trusted by the phone... I have the phone sitting on the table with a piece of tape holding the power button in causing the screen to stay on and keep the endless countdown going... hoping that kills it quick..... I guess that's the solution to this problem if anyone else may happen to come across the same thing lol

Plug in a USB otg cable and a USB mouse.
Light a fire for a man and you`ll warm him for a few hours...Light a man on fire and you`ll warm him for the rest of his life

How did you get yourself into that situation, lol. This is why I slightly perfer the Galaxy's because you can just pop the battery off. I get a HTC and just try and do as little as possible, and quad check everything.
Did you get it done atleast?

When you are holding the power button down and it starts to count down shine a flashlight at the light sensor to the left of the speaker on the top (or hold it under a bright light). I had this happen to me before where it wouldn't simulate the battery pull. Just sat there. Apparently the phone has a built in defense to not reset in low light situations in case you accidentally hit the power button while the phone is in your pocket. The flashlight on the sensor trick works. http://forum.xda-developers.com/showthread.php?t=2314952

Black screen, no download mode

My LG G2 downloaded an update last night and I accepted the install. I woke up to a blank screen and i Can't do anything on it. No download mode or recovery. It was rooted before hand. VS980 Please someone help me. I see the lg screen for a few seconds then it goes all blank. If its plugged into the computer the LG screen only comes up for a split second.
Charge it for a few hours and go from there. Sounds like the battery is dead.
If you hold the power button does it continually vibrate in spurts? If so, then it's most likely just a dead battery.
Here's some more help for you.
Hold down power + volume down...the phone will turn off, but don't release them yet. It will flash LG logo for a split second and then turn off completely and stay off. You may release the buttons now.
Press and hold power + volume down. when you see the LG logo release the power button ONLY and then quickly press it and hold again until you boot into recovery.
Hit power twice to enter recovery

Holding volume up + plugging in your USB to the computer will get you to download mode as well and let you stock the phone.

[Q] How to switch off phone with broken screen?

Dear Xiaomi Mi3 users,
I'm sorry if this question has been asked before.
Basically my touch screen is totally cracked and unresponsive. I need to replace my screen. I ordered a screen and repair kit from China, and it has arrived. However the instructions say that I should switch off my phone before attempting to replace the screen. The problem is, the screened is cracked and I can't press any buttons. Holding the power button for a long time simply reboots my phone, it doesn't shut it down.
What should I do???
Thanks!!

1) when your phone reboots at that time press the volume up button , the phone will enter into recovery mode and from there you can turn of your phone without even touching your screen
2) you can plug in a PC Mouse t your phone sing a OTG cable and can access all the functions without touching the screen

After restarting, when you see the MI LOGO, hold power & volume down button, it will execute the fastboot and just wait for a second your phone will automatically shuts off.

Is it not "Volume Up" and "Power Button"? iso just "Volume Up" button.
I just had to do this too.
Hold power button for ten seconds to reboot.
Immediately switch to power + volume up to get to fastboot
But the fastboot screen does not automatically shut down. And holding down the power button for ten seconds reboots again. And because of my broken screen, i can't see the fastboot menu.
In the end I plugged it into a computer, installed adb, and did adb shell and adb reboot -p (-p for poweroff)
Now, back to replacing my screen, being very careful not to press the power button this time.
Hi,
Today I had the same problem. Xiaomi Redmi 4x with broken screnn and I could not shut it down to replace its display. After a few tries I found the solution.
Just press Power button and Volume Down and DON'T RELEASE THEM UNTIL THE SMARTPHONE IS COMPLETLEY SHUTDOWN. After about 8 seconds the smartphone will reset . Don't release the Power and Volume Down buttons , wait and the smartphone will boot again in another mode. Continue to keep both buttons pressed and after about 10-15 seconds it will really shutdown.
Good luck!

Black Screen, won't do anything.

Hello,
I have a rooted and TWRP installed but otherwise stock 5.something T710 that I had worked on months ago. It's been great and my daughter had been using it to watch videos a couple days ago. I took the tablet from her at the end of our road trip and noticed it had about 63% battery left. I left it in the truck while we went to the movies(about 40 degrees f outsides) and then drove home without ever touching it until we got home. I went to use it when we got home and it would not turn on. I plugged it in to let it charge thinking it died for some reason, using the stock charger, though battery icon never appeared. The next morning I went to check it and it still would not turn on.
When I press the power button or plug in or unplug the charger the Recent and Back soft key lights will turn on for a second, then turn back off again.
I've tried:
Holding the power button down alone for over 3 minutes.
Held the power and volume up button for over a minute
Power and volume down for over a minute.
Home, volume down and power for over a minute
Home, volume up and power for over a minute.
I can connect it to my computer and it recognizes that my Tab S2 is connected but no files show as the default for the device was just charging mode and not the file modes.
Odin3 v3.10.7 recognizes it as connected. But fails to send the TWRP file again.
Any help?
Since the soft keys light up and the computer recognizes the device, it sounds like maybe the tab is still working but with no display? By any chance did you have adb working? I f so you could try rebooting, or booting into recovery to see if you see anything on the screen. It's possible that when you held the button combos, that it did boot into download and recovery but you couldn't see anything? In which case it could be a hardware problem. Hopefully it will fix itself! Sorry I can't be of more help..
Well adb shows the device as unauthorized. Reboot command says the same thing.
The home key is unresponsive to my finger print unlocks and no sound plays when I try to adjust the volume, like the ding sound it makes to hear if this is the volume level I want. There are never any of the capacitive touch vibrations or whatever its called to feel when you press a button on the screen.
I was wondering if it had something to do with hardware it's just strange that it would stop working from just being in my truck. From my knowledge it was never dropped or bumped heavily or anything, at least recently.
I guess it is possible something just burned up inside, that would be inconvenient, I've got to look up if its still in warranty. I love the size and performance of this thing.
Thanks for replying, hopefully more to come.
Still can't get it to work, same issues as above. I let the battery fully die which took about 2+weeks from the initial post. Which is to say that eventually the back and recent buttons stopped lighting up. I recharged it and after holding the power button for a few seconds the same condition repeated itself. If I touch the power button or home button the back and recent button back lights turn on for a moment and turn off again. There is no other indication of life. I would assume if it was just a dead screen then I should feel it try to turn on.
If I had to replace parts which ones should I look at first? Probably just the main board?
Buy a new one. Send yours in as defect. Done.

I see that is an old thread, but I having the same issue to a certain degree. The screen goes dark, but I can see the back light. If I play around enough times, (pressing the back and process button, before pressing the sensor button... Sometime, pressing the volume buttons and back button before pressing the sensor button), everything goes back to normal. Of course, it some random time, even when I am reading a web page or some other activity, it will go back to black.
So has anyone figured out what this issue actually might be? I thought maybe it was an issue with the ROM I was using, so I just moved over to LineageOS 16, but the problem still continues!

My Nexus One screen not working after changing upper motherboard

Hi! Hope all of you are well

Between my brother and I did the job, we put all in the same way the old mobo was, the phone charges until charge LED goes green as normal, the new Power button works because when I press it the phone does the typical boot vibration, but screen dead, it doesn't show nothing, even after waiting a few minutes until it fully boots the OS the Home, Menu, Back and Search buttons doesn't vibrate after pressing them
Any help and suggestions will be well received and appreciated
Thanks in advance!
