[Q] Nexus 7 will only boot through bootloader menu

Hi all,
My new Nexus 7 (2013 model) arrived today, and it seems that it can only boot up through the bootloader menu, i.e. the power button does not work properly. When plugged in, the battery charging icon does appear for a few seconds before disappearing.
The problem is that holding down the power button does not turn the device on. Holding down volume down+power button works correctly and shows the bootloader menu, and from there selecting "Start" is the only way to actually boot the device. When plugged in to a power source (outlet or computer), holding down the power button causes the battery charging icon to appear, disappear, and reappear constantly. Holding down the power button when unplugged shows no response on the screen, even after holding down for a full minute. Once the device is booted, the power button works perfectly for locking, unlocking, and showing the power off menu.
I already tried doing a factory reset, which did not help at all. Is there anything I can do to fix this problem?
Your best bet is to ask in your device's forum section as this section is for the 2012 version.

[Q] nexus 7 stuck in annoying boot loop

Hi guys! Just got a nexus 7 1st gen and its stuck in a bootloop. It seems that it thinks the power button is constantly pushed in when its not which is causing it to restart constantly. Ive managed to get it to stay on by wedging down the volume up key but i cant use the sleep/wake or volume up and as soon as i let go of the volume up it thinks the power button has been pressed and asks me if i want to power down, but before i can press anything it resets. I have put new buttons in this morning to no avail and cant find anyone with the same problem and was wondering if anyone one here had any idea?

Problem with A3 SM-A300FU

My A3 doesn't "wake up" from stand-by.
If I reset it keeping pressed power up button, it correctly reboots, I can see all boot process and it correctly reachs the starting home page.
If I keep touching screen, open apps, navigate from various menu all works fine. But when I leave it without pressing any button/screen for 10/15 sec (display power off delay) the screen correctly goes black, but there's no way to wake up it again although it seems working. The A3 "under" works because plugging to AC Adapter beeps the sound of charging in progress, PC (Kies or SmartSwitch) detect it correctly; only the screen remains black.
I already tried to wipe and even reflashed last firware with Odin but with no luck.
Is there anything else that I can try (except send it to repair center...)?
Thanks in adv

P.S. When I call It from another phone, it rings but the LCD remains black and doesn't respond clicking vol +, vol - and home buttons
P.S. 2 Thinks become "funny": Home button, vol + & vol - don't work at all. Power button powers off display, but long pressing it, doesn't pop up power off/reboot menu. Softkeys don't work.
Sounds like SoD. Try installing the app "Wake Lock" and choose the PARTIAL_WAKE_LOCK option.

oneplus 6t stuck on unlock warning screen

Hi I had my oneplus 6t for 3 days and It's unlocked and rooted it was running fine until it runs out of battery and died and when I plugged it in and charge it the phone got stuck on the unlock warning screen now it doesn't turn off or on I tried the following:
hold the power button for 30 sec
hold the power button and volume down button for 30 sec
hold the power button and volume up and down for 30 sec ( this got the screen to blink only)
I plugged the phone to my mac and tried these command ( fastboot devices) (adb devices) nothing shows up on the cmd

Click to expand...
Click to collapse
Unplug the phone, hold the power button.
It will eventually reboot.
If not hold power and volume down.
There is a known problem after rooting, don't turn the device off and plug it in.
Unlock warning screen stuck "Reboot" fix.
Mine did the same thing the other day and after all the research found out it's Volume UP +Power press for as long as possible, for me it rebooted in 15 seconds. But I'd advice holding it as long as you feel vibrate and reboot. Tried more than few times for mine works Everytime. Don't plug it in while it's off and turn it on to prevent it from getting stuck again.
