Tablet misbehaving, powered off, but not back on

I was watching netflix, and the interface was acting up, acting laggy, so I powered down the unit to restart it. It powered off, then when I tried to turn it back on, nothing happened. The screen stays black and it just vibrates after 10 sec.
Things I have tried:
Press reset button in hole for 10+ sec, also for less than 2 sec (click it) - no reaction
Press power and hold for 10+ sec - vibrates, like it's starting up, but nothing else
Press power and vol down (also vol up) - same vibration at 10 sec, but nothing else
Had a full charge when this happened, I had just pulled it & the dock off the charger.
When I plug the charger in, I get a solid green light.
Rooted on stock rom with original locked bootloader.
Hoping I can get this thing back on. I'd rather not send the tablet out to anyone or return it with it still full of apps and data.
Edit: Also, when connected to my PC, I get a "USB device has malfunctioned and is not recognized"... oh boy, that doesn't sound good at all.
Edit 2: I don't know if it's pertinent, but the last thing I did before resetting the tablet was adjust Volume+ from 8 to 10. "MusicFX" crashed shortly after that, and the volume didn't actually go up. That combined with the laggy netflix interface is why I reset it. Previously, I've only been skyping and using snes emulators off the market, and browsing the net. I can't imagine why this happened.

I know that when I used to turn off my tablet it would turn off and not vibrate. It was still running with the screen off son I had to hold the button till it vibrated then held it down again. It seems you already tried that but try it out again. Also make sure its completely off. When you connect it to computer it should not see anything if its off.

Thank you for your suggestion, it did not work; it just vibrated both times. I reconnected the keyboard dock and plugged it in via the dock to see if that had any effect, and all the same it is shown as an unrecognized usb device, which in my experience means the usb device has a hardware failure. An Asus support rep has suggested that it would need warranty service. Fortunately I'm still within my return period to BBY, so I will exchange it with them. Just don't like the idea of leaving my unprotected email and other accounts open to anyone who might be able to repair it and get it running again without erasing it.

Find out vendor ID and and device ID of this unknown device. If it is 0955:7030, your device is in APX mode (check if the volume-up button is stuck).

It's just not coming back. I decided to go ahead and exchange it. I'll have to change a crap ton of passwords now, but whatevs. I wish I had an idea of what killed it though.
The vol button was not stuck, it had a definite click 'action' to it on both sides. Wish I had seen your post a half hour ago.
Edit: Wait -- I just crawled through the event logs: Driver Management concluded the process to install driver NULL Driver for Device Instance ID USB\VID_0955&PID_7030\5&250F0A09&0&5 with the following status: 0xe0000203.
Is there a way to get it out of APX mode??

Usually, not pressing Volume-up while powering on is enough.
I'd say your tablet is really defective.

TF700 Crashed

Not really sure what happened, but I left my tablet alone for about 5 days. Had to plug it in to charge it back up obviously. The next day turned it on, and all I get is it vibrates once, than just vibrates infinitely screen is not turning on I think. I tried the reset button, recovery mode nothing happens just goes straight back to vibrating. It seems I can enter APX mode, since it vibrates once and than stops my computer sees it but cant find device software to install for it, and shows up on devices as "APX" unidentified.
I even popped it open, pulled the power connector for the board and backup battery let it sit for a day; plugged it back in and still same issue as before. I bought it 9 months ago in December only real issue before this, is that it froze a few times but went away on its on after a reset.

You can give this a shot...:fingers-crossed: you need to hold the power button + volume up for about 10 seconds. You will feel the first vibration and keep holding both buttons for another few seconds then you will feel the second vibration. After the second vibration, you need to release both buttons as the same time then wait for a few seconds after that. You can try to power it up and see if it works.. Please report back and good luck.. :fingers-crossed:

[Q] Black screen + vibrate, Titanium Backup crash

Hey guys,
I unlocked my TF700T using the Asus unlock tool, then rooted it with Kingo App.
I opened a terminal on the device and ran "su" to verify that I had root, which worked I did.
I then installed com.keramidas.TitaniumBackup ("Titanium Backup ★ root") and began a full backup, but at 65% my Internet connection dropped (not sure if related, but interesting timing) and the system froze. After 10 minutes at 65% I powered off the device in an attempt to reset.
However, the device now will not start. The screen remains unlit. Charge LED will not light. Holding Power for 6 seconds and holding Power + VolDown result in a short (500ms?) vibrate, but nothing more.
I have not yet tried a paperclip reset, or connecting the dock. I have tried connecting to both USB and power. With USB, Windows 8 detects it as a crashed device (no surprise there) and fails to install a driver.
I suspect I'm hosed, but I'd be interested to learn why.
Any theories or suggestions?
---
Android 4.2.1
Firmware V10.6.1.14.10

Same behavior with dock connected.

After connecting power through the dock, the charge LEDs have both lit.

Ah just re-read and realised you only get a vibration but no screen..... Bummer - not sure what to suggest for that one.

Well, thanks for trying
Sell it for parts, I reckon.

Since you don't have much options, you can try these. I think that there were a few users were running into this problem and tried this. Some reported back that it was not working and some did not say anything. So I don't know if it works or not but you could give it a shot.
Try these combinations:
1. Hold the power button + volume up. You will feel the first vibration and keep holding both buttons until you feel the second vibration. As soon as you feel the second vibration, you need to release the volume up button But you must keep holding the power button. You need to hold the power button until you feel the third vibration. The third vibration is when your device is trying to boot up. You may want to try a few times with those sequences above in hope that it will bring up your bootloader.
2. If the above sequences don't work out for you, you can try this second solution. However, you need to hold both power button + volume down this time with those sequences above. Please report back with the outcome, thanks and good luck...:fingers-crossed:

Moto G won't Boot after factory reset

I bought a Moto G for my little brother and it arrived yesterday. The first Problem which appeared was that I couldn't download apps. I started the factory reset and now it won't Boot anymore. There's just a black screen after the Boot animation and I can't even turn it off. Should I send it back to Motorola or should I try to fix it?
Gesendet von meinem Nexus 4 mit Tapatalk

If you have only done this what you have described then i would say, yes, send it back.
Because only a factory reset should not bring your phone in this state.
but
Have you tried to press and hold the power button for 20 seconds?
Then it should be forced to switch off.
Sure......you have the option to fiddle around yourself.
In that case see the thread Restore Stock Firmware if above mentioned does not resolve your stuck system

I tried but the phone restarts. I sent a ticket to the Motorola support. Probably they'll tell me that I should sent it back.

Then lets see what Motorola says.

I have the same problem but it doesn't even let me turn the phone off

I have a the same problem, but i have a few more details:
It doesn't actually get to a boot animation, just to the Motorola logo screen that usually comes before the boot animation. it stays on that screen for 15 seconds, and vibrates 10 seconds into said 15 seconds, like the phone does when it goes into safe mode.
If you hold the power button for 20 seconds, it does turn off, only to turn right back on again and do the same thing
its is actually off for about 10 seconds, which is long enough to get into the fastboot menu, but every option that is selected from there gets the same old boot sequence i described before.
My moto g started doing this when i was using it on 14% battery, i went into the recent apps menu (bottom left button next to home button) when it just froze on that menu, but not showing any open apps. It then just turned off, no shutdown sequence, and when i tried to turn it back on the LED Indicator flashed like when it doesn't have enough battery to turn on. i then went into the fastboot menu (power+vol down) for no particular reason, and selected the QCOM option at the bottom out of curiosity. the notification light then did its low battery flash and the phone turned off. I then later plugged it in to charge and it has been stuck in that boot sequence with me running the battery down and trying everything in power, except contacting motorola. ( i didnt conatct motorola as my phone's screen got cracked about three weeks before all this started, so that would mean they wouldnt fix it for free)

My Moto g phone is not working even after factory reset ,, the error is it goes white or dark and i have to switch it off again..Sometimes it starts working and then again it gets switched off then again u have try factory reset or delete cache and just hope it work ..
Any one can help me with this issue please reply

I did factory reset to my Micromax Q350. Before resetting it was running Android Marshmallow 6.0.1 with July 2016 security updates. Now when I reboot the device, after language and SIM options, it asks me to select a WiFi. But it is stuck in "checking connection... this can take a while", even when the same WiFi is working with other devices. The Select WiFi and Checking connection pages can't be skipped as the Skip button is grayed out.
My device is not rooted and I don't want to root is as long as possible, so this answer doesn't help me.
I have tried various options suggested in forums and nothing is working for me. I have tried with and without SIM cards and Micro SD card as well.

Held power button, (or power+volume down) for a while, not too sure. Restarted after that. Just try all combination of keys for a while, might work.

[Q] Constant vibration

Hi everybody!
I checked through all threads here about my problem, but could not find a solution.
One day ago the battery of my tab ASUS TF700 fully drained.
So I connected the tab to the charger and in some time tried to turn on it.
Nothing happened, it just started vibrating constantly.
The only method helped me stop vibration is hard reboot (power + volume).
When I hold only power button it stops vibrating for a second, make short vibration, again pause and then starts vibrating.
Connection to the monitor by HDMI didn't show anything.
I didn't do any updates right before this accident.
No root, no unlocks etc.
Please help me, I am desperately frustrated.
PS. there are some old trends with the similar problems, but without solutions.

Can you boot into the bootloader?
Push and hold Volume Down (left side of the rocker) and Power. The tab should vibrate twice, let go when you see tiny script and three icons.
Push Volume Up with the RCK icon flashing. If you get an Android falling over with an exclamamtion mark, you're good: your stock recovery is working.
You probably corrupted your system when you let the tablet crash in the middle of something. If the stock recovery is still working you can re-flash the firmware. Let me know if you can get there and I'll tell you how.

Hi,berndblb!
Thanks for advise.
Unfortunately my asus doesn't stop vibrating when I push and hold Volume Down (left side of the rocker) and Power.
So there are two options:
1. If I push and hold Volume Down (left side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and continues vibrating constantly without any interruptions.
2. If I push and hold Volume Up (right side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and finanlly stops vibrating. One trick: I have to push and hold till the moment when the device makes one short vibration, and only after the moment when vibration stops finally I can release the buttons.
That is all I managed to discover pushing and holding buttons.

Sorry friend, I think your tablet is hosed....
Pushing Power and Volume Up (right side of the rocker) should get you into APX mode, which is usually the last thing working if everything else is messed up.
But even if you get to APX - it's useless unless your tablelt is unlocked and you previously created your device specific nvflash blobs.
I'm afraid a new main board is your only option....

I have finally won
The solution was simple:
1. I let the tablet vibrating till the battery totally discharged (it took the whole night).
2. Vibration of course stopped.
3. I charged the battery a little and switched on the tablet.
4. Tablet launched in normal regime, all data and system were saved, even after I tried to make a hard reset (I suspect it didn't work out).
After that it only once rebooted without any reason, but that's all.
So several days passed, the tablet works without any problems.

It is good to hear that you have your tf700 back....:good: Thanks for the report back...
BTW, are you going to unlock your device and generate the Nvflash blobs? If it occurred once, It could come back again and hope for lucks again...:laugh: Just my two cents..
