ADT-3 bricked? - Android TV General

I have been trying to flash 13 on my ADT-3, and I seem to have screwed up. Now all I get is a bootloop, and if I hold the device button on boot, I get the screen with the green Android/No Command.
Any suggestions to try to recover?

You'll need to have the usb cable connected to a computer in order for a button press to establish a usb burn mode connection. When the button press is done, if the device doesn't detect a usb connection, it will instead skip to booting to recovery.

then you need to hold the "only" button again ~ you will see the menu

HELP**Urgent** 'unit won't hard reset'

My usb cable detached during the rom update ... now it won't start and neither soft or hard reset works.
Please ... any suggestions
Plug it back in and re-run the update
It won't start so it makes no connection to active synch on the pc
Have you tried the boot loader mode. TO activate this mode, hold down the power button, lights button and press the reset button. The screen should go blank and have serial written on it. Once you plug in the usb, this will change to USB. Start the update again.
thanks both of you - worked and so relieved.
thought it was kaput!

[GUIDE] Entering ADB/Fastboot/APX mode instructions

I wrote this awhile back to provide known methods to enter each of these modes. I know it's rather wordy, but may help those that are newer to all this. See the link below for a more concise write-up. I'll try to keep this updated with any corrections and/or new methods and feedback is very welcome.
How To Enter APX, Fastboot Mode and Recovery menu​
Special thanks goes out to tobdaryl for providing the foundation for this guide and to daws for
providing a previously unknown method (USB cable plug in while tablet is turned off).​
Pertinent links:
The methods below written more concisely by tobdaryl: How to enter APX mode or Bootloader-recovery menu
Universal Naked Drivers (for APX/ADB/Fastboot modes): [ADB/FB/APX Driver] Universal Naked Driver 0.72
To install the SDK tools & drivers in Windows 7 (and other versions?): [HOWTO] Install Google SDK and ADB drivers...
The following instructions are written on how to enter APX mode. To enter Fastboot and Recovery modes, simply follow the same instructions but use the Volume Down button. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: The screen remains blank in APX mode.
When your tablet is turned off, to enter APX mode:
Make sure your USB cable is connected to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure the USB cable is not plugged into your tablet (but is connected to your PC). While pressing the Volume Up button, plug the USB cable into your tablet. Release the Volume Up button after a few seconds (modified from daws' suggested method).
When your tablet is up and running, to enter APX mode:
Turn your tablet off and wait a few seconds. Connect your USB cable to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds.
From a tablet based terminal emulator, type: su and hit the Enter key, then type: reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One suggested app (by tobdaryl) is the free Android Terminal Emulator from Google Play. Note: You must be rooted for this to work.
Press the tablet reset with a paperclip while pressing the Volume Up button until the screen remains blank for a few seconds (the reset is located about either 25mm or 1" below the sdcard slot). Note: Do not press hard!
When your tablet is in Fastboot mode, to enter APX mode:
While pressing the Volume Up button, press the Power button for 10 seconds. Release both buttons a few seconds after the screen goes blank. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally.
Make sure your tablet has the USB cable connected to your PC. Open a command prompt on your PC, navigate to the folder containing fastboot.exe, type: fastboot -i 0x0B05 reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally. Note: Newer versions of fastboot.exe do not require the "-i 0x0B05" option.
Or, as a last resort!
Remove your tablet's cover, disconnect the battery, press and hold the volume up button, and reconnect the battery!
The following instructions are written on how to switch from one mode to another (not covered above).
When your tablet is up and running, to enter Fastboot or Recovery mode:
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot-bootloader and hit the Enter key. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: I was unable to verify this method possibly due to having the AndroidRoot.mobi custom bootloader. This method only performs a regular reboot for me.

When your tablet is in Recovery mode (TWRP v2.3.x), to enter Fastboot mode:
Select the "Reboot" option and then select the "System" option while pressing the Volume Down button until the screen remains blank for a few seconds. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, wait 5 seconds for the icons to appear, and follow the instructions to select/confirm fastboot mode.

Nice guide! Thanks for taking the time to gather the information and create this guide.
It is clear, detailed, and easy to follow.
It should be a stickied.
Hi I tried connecting my device to my computer after holding down the buttons to get into APX mode. And after about 5 seconds I heard a connection sound then Windows told me the USB device malfuntioned. Any idea why?? I'm trying to fixed my friend's soft bricked tablet which cannot get into fastboot mode.

A couple of quick thoughts if it's not the device itself: check to make sure the cable is good, try a different USB port, and try re-installing the drivers (using the Universal Naked drivers, specifically the APX one included in the package). I've had troubles on one pc where it would connect and disconnect - it was either the USB port acting flaky or the OEM cable I was using...
Watching Windows device manager, is it showing it as an APX device or something else before it disconnects? Also, what kind of error?
Hopefully some others may have added suggestions...good luck!

Ah I seemed to fix it when I held down the volume button while the tablet was off and plugged it in. Thanks for the help!

No problem at all and glad to hear it wasn't a complicated fix! With APX and other modes, do have the two methods. Holding both buttons at same time, but I do find somehow it doesn't always recognize them (maybe I'm not holding the volume button solidly?). As worked for you, the other option is to have it powered off, hold the volume button, and then plugging it in to get it to power on and go into APX mode (remembering it's just a black screen but can tell by checking Windows device manager - mostly mentioned for any others that may come across this!).
If have more questions on the rest of the restore process, might be good to start a fresh post for the remaining steps. Good luck with getting it back up and going!
Hi @wha2do,

Thanks to your guide, I removed that portion and it worked like a charm. Thank you man

Only turn on in fastboot mode

My nexus 4 isn't turning on in any way.
If i connect the power cable a red light blink once and stop, pressing the power button nothing happens. The only way to get some activity it's pressing the volume down + power and connect the power cable, but turn on in the fastboot mode and can get out of there. If i try recovery mode the phone dies, if i try to reboot the phone dies, if try to normal boot the phone dies.
I can turn on in download mode, but the LGNPST don't recognize it.
Fastboot commands via prompt are fine, unless i need to do something that reboot the phone.
Someone can help me?

sorry for delay to response, i think i found the problem: the battery

stuck on boot menu

Hi,
i had to reboot my phone cuz of issues and out of no-where my phone got stuck on the boot menu.
when i'm talking about the boot menu, i talk about the menu where you can select 'start, restart bootloader, recovery mode, etc'.
when i connect an USB it doesn't get recognized, but i do hear the sound from windows after about 5 minutes that a usb has been connected. ADB doesn't see the device.
its entirely stuck and can't select a select a option using the volume buttons and power buttons, they appear to do nothing. also the phone says its charging and the USB is connected while it's not.
this seems to be a screen freeze, but i don't know how to fix it.

[GUIDE] Booting your OnePlus X with a broken power button

Got a broken power button and need to turn on your OnePlus X?
As long as one of your volume buttons and your microUSB port still work, you're lucky.
If the volume down button is working:
1. Press and hold the volume down button.
2. Connect to a USB power source.
3. The phone should vibrate and boot into the recovery. You can release the volume button at that point.
4. If you have the stock OnePlus recovery installed just tap "English", "Exit" (if present), then "Reboot".
5. Your phone should now boot up!
If only the volume up button is working, things get a bit tricky.
Before you start, read through all of the steps and the paragraph below to make sure this goes as smooth as possible.
1. Connect your device to a USB power source without pressing any button.
2. Wait for about half a second, then press and hold the volume up button.
3. If you've hit the right moment, your device will boot to fastboot mode.
4. Connect to a PC and run the command "fastboot reboot".
(If you don't know what fastboot is or you haven't set it up yet you should be able to find plenty of guides online.)
A word of caution on finding the right moment to hit the volume button:
Start with longer delays and work from there. If you hit the volume up button too early the phone will enter EDL mode, which can be hard or annoying to get out of. EDL is Qualcomm's low-level Emergency Download Mode which allows flashing the device.
When entering EDL mode the phone won't vibrate and the screen will stay off. The phone remains in EDL mode after disconnecting the USB plug.
Normally you could press and hold the power button until a hard reset to get out of there, but in this case you have the following options:
- Unplug the battery to power down the device completely if your device happens to be open.
- Wait? For as long as it takes for your device to reset from this mode on its own or for the battery to run out. idk, good luck.
- Use an EDL mode flashing tool on a PC to send the power reset command to your device. This could be viable if you have already used such a tool before, e.g. by following the "Mega UnBrick Guide" by Naman Bhalla. Alternatively you could dive into this cross platform command-line tool, which works on WIndows, Linux and macOS. Using this approach is a bit overkill and quite the tangent from what you're actually trying to do, but being able to make use of EDL can come in handy in other situations as well when you're tinkering with your Android device so taking that detour might just be worth the time.
Awesome, it worked for me.
-Incase you have entered into EDL mode, then continue charging your mobile, it will be back to old state after sometime (12 hours maybe).
- To get fastboot mode, first insert power cable then wait for vibration/ screen light illumination after that press volume up button. if you press volume up button before inserting power cable, then it will go to EDL mode, so be careful about it.
