I have a generic Chinese tablet with Intel Atom Z3735F CPU. It came with Android 4.4 but since that's useless to me and since this CPU and chipset supports it, I wanted to try and install Windows 10 on it. I booted from a usb stick and Windows 10 setup started loading, but soon after that, screen turned black. I didn't even make it to setup language selection screen, meaning I didn't actually get to delete or install anything. (I doubt trying to install Windows had to do with anything since it didn't get far at all but I thought it is worth mentioning.) Now it won't turn on or charge. When I plug in the charger, screen flashes white for a split second every 20 seconds. There is no boot logo or anything.
I tried everything I can to fix it. So far I tried:
* Resetting by pressing power and volute down buttons at the same time (I tried power + volume up as well)
* Disconnecting the battery and waiting 24 hours.
* Charging for about 12 hours (It doesn't seem to charge and before the screen went black it had almost 70% charge)
But no matter what I did, it won't boot. When I plug in the charger or press the power button, screen just blinks white for a second and repeats blinking every 20 second. I can't even turn it off unless I remove the battery or press the power and volume down buttons. I am at a loss as to what to do. I don't see a reset button anywhere on the tablet and I don't have a usb jig. (Even if I could get a jig, I doubt it would work with this tablet)
Please give me advice as to how to fix this.
So... I am guessing no one has any ideas or suggestions?

My transformer has been my right hand since June and all of the sudden I'm without it. Was listening to a podcast via beyondpod this morning and paused the audio via my BT headset. Went to a meeting, then lunch. Came back two hours later and my tablet wouldn't turn on. I figured it was a sleep of death that randomly occurs so I held the power button in for 30 seconds or so to reboot, but that didn't work. It was still on because I could hear audio notifications for calendar appointments.
Tried the power button for 60-90 seconds, still nothing on screen. In the past I've been able to plug in the charger when this occurred and it would pop the screen on, tried that, but got no results.
I tried plugging it into my laptop to see if I could get ADB active and do a reboot. Windows saw the device and loaded the ADB driver, but if I tried adb devices it showed no devices. I long pressed the power button again and the windows device manager reset, adb devices now showed the transformer, but in offline mode. I couldn't run any commands.
Next I tried the "soft reset" utilizing the volume up and power button. This didn't do anything, except that the next time I attached it to my laptop it prompted me for an APX driver. I didn't know at the time this was for NVFlash (I rooted my device before the SBK was out with the initial blob tools from androidroot.mobi).
Now when I hook up my transformer I get no response from my computer and no response from the buttons on my tablet.
I'm at a loss and would love any suggestions or ideas to get my tablet back up and running.
This is resolved, I was finally able to get it rebooted via the volume down button and power while hooked to my laptop. I have no clue what was going on with it, but its still acting hinky.
Do we have any hardware diagnostics?
my tablet just started doing the same thing. O_O asus is trying to get us to buy their new slates, so they broke our current ones. /s
Something is seriously wonky here. My wifi keeps turning shutting down but being stuck at turning off. My power button is very inconsistent.
I think I'm going to fully wipe the system and start from scratch...
Been a couple months, but I'm back in the frozen state again. I charged my TF101 over night, pulled it off the charger and validated it was in a SOD. I put it in my sleeve and headed to the office. I turned on my BT headset to listen to a Podcast, but it didn't connect. I grabbed the tablet and it was screen on, frozen at 7:29am.
I can't for the life of me get this thing to reboot. I've held the power button in for 60 seconds, tried power button with volume down to boot recovery. I tried on AC power and off. I tried to hook to my PC, but the USB is not recognized at all.
I don't know if I just need to let this thing die (which will take forever) or what to do to get this rebooted.
Power button feels like it is catching when I press it in...
If you take off the outer bezel (be mindful of your micro sd card if you have one) you can push the actual power button itself. It should be a simple hold the button down for about 3-5 seconds and it'll reboot.
Hello,
I flashed the latest LRX22C image on my nexus 5 today.Had flashed it clean,wiping data,cache and system etc except the Internal Storage.Then I flashed the SUPERSU 2.37 ZIP .Everything was fine for about 4 hours.Then suddenly when I pressed the power button to turn the screen off,it was not turning off and the "Switch off" mode was popping up instead .Then, when I got a call,it switched off.The phone won't turn on again.It starts,the Google Boot Splash appears and the bootanimation starts for like 2 seconds and it switches off.Same thing for bootloader mode.
Please Help me!
EDIT: Now its turning on by itself and switches off in 2 seconds!
Sounds like a bad power switch to me, but of course that is just my opinion. :good:
sounds like a mech issue.

I have the same problem on mine now... Basically my phone powered down around 45%. Battery. At the time i thought it was dead... But it wasnt. When i would plug into external power, either usb or through wireless charging it would power cycle continuously at the android splash screen.... (1 to 2 second intervals - even if i booted into fastboot) Interestingly it would never go to the battery charging mode. But automatically boot on charge... It did this for about 6 hours then i gave up and left it unplugged for a day. I plugged it back in and it started power cycling again, however this time on its third boot it came back to life . thats when i discovered i still had 40% battery... I dont know what exactly made it boot but it did. Oddly also on boot, it started optimising apps and finishing install again. I checked the md5 before I installed the update so no issue there. Since it powered up i have powered the phone off using the power button long push and let the phone power down. After doing this when i plug the phone in to usb charge it goes to the charge screen. No issue. That said, if i try to power up while tethered and charging it will not allow it. It just stays at the charge screen. As soon as i unplug the usb the power button allows the phone to power up and work... When booted up it charges as normal when plugged in. Im convinced there is an issue with the power management drivers or drivers for the button controls. My phone worked fine until the 5.0.1 update was installed. On my nexus 5. Anyone else or just us two? Ive had a hard time finding people posting on this issue.
I have a 2nd Gen Moto G that was pretty much in mint condition & prior to yesterday it showed no signs of any potential problems. Then last night the screen completely froze & wouldn't allow any input. The phone then shut itself off & I figured it would just restart & be fine. Instead it went into a constant boot loop where it reaches the white "M" animation screen then shuts right back down. I played around with it for a few hours today & did a ton of searching on the internet with no results.
I also should state that the battery did not die when this happened. I mention that because there were some posts where people let their battery go completely dead then they couldn't get their Moto G to power back on, however that was not case for me as the battery had well over 50% charge when this happened.
Things I have tried in order to fix this:
Using a different charger (both wall and USB to the computer).
-Holding down the power button for 7-10 seconds while plugged in.
-Holding down the power button for 7-10 seconds while not plugged in.
-Holding down the power button for 2 minutes or more (while plugged in and while not plugged in).
-Holding down the power button and volume up buttons until the phone starts (while plugged in and while not plugged in).
-Holding down the power and volume down buttons for 2 minutes or more (while plugged in and while not plugged in).
Now this step does bring up the fastboot menu however selecting any option in this menu just causes the phone to back into the boot loop. And yes I know how to access options in this menu (down volume to scroll & up volume or power button to select).
So basically everything just sends the phone into boot loop. Is the phone toast? Also I should mention that all day today it would randomly try to start itself & get to the Moto animation screen & then shut down & that was while it was sitting on the desk & I hadn't even touched it.
If the phone is toast is there any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
Alright so seeing as no one has any suggestions (understandably) & based on the searching I've done I'm assuming that the phone is just DOA. However does anyone know a possible answer to my second question which is, if the phone is un-savable is there still any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
My LG G Flex 2 H950 was working fine, running google maps and playing music, plugged in to the car charger. Within minutes of leaving the car the phone was dead - I could not power it on. I can usually get it to show the LG logo by trying to start in Recovery Mode (holding the power and volume-down buttons for several seconds) but then the logo just disappears after a few seconds and the phone does not power on. But sometimes when I try this the red LED blinks on the phone screen and the logo may or may not appear. Sometimes (50%) when I plug the phone in to my Windows 10 desktop, the computer plays a tone to indicate a new device has been connected, but no icon appears in the list of hard drives or devices.
I think the battery is charging normally - when I connect the phone to a USB volt meter it usually (but not always) shows a normal amount of amperage flowing, and just now when I tried to start the phone it showed the battery charge icon on the phone screen (it doesn't usually do this) and showed 100% charge.
Is there anything else I can try, even if just to get the phone running long enough to backup my text messages etc?
Is there any way to test what's actually wrong? I'd hate to spend money on a new battery or charging port etc for a slim chance to temporarily fix a phone that seems like it's dying.
Thanks for any advice or suggestions...
Hey, i've got the same problem since today. i was watching youtube videos when the phone suddenly stopped working. did you already find the problem?
Sorry for my bad englisch ( Dutch)
No - not solved, phone still dead. Still would love to hear any advice...
I used to have the exact same problem as you - bootloops at the LG logo, no recovery etc. After some reading it seemed that the battery was the root of the problem, and after replacing the battery my phone was back to life - no issues ever since. I recommend you check if the battery is the issue by connecting it to a normal charger (i.e. not charging from a PC) and powering it on, by holding the power button at the battery charging screen. If it powers on normally then it's most likely a battery issue, which can be easily fixed. Cheers!
Hello! I could not find a section for my phone, so I am posting here.
My Zenfone 5 Selfie/Lite (ZC600KL) randomly "bricked". After being left alone charging for 20 minutes, when I came back it was turned off. Holding the power button resulted in the phone showing the "Powered by Android" logo, then the ASUS logo, and stop there.
I don't think it's a battery issue as it always lasted a long period of time; this is the first time anything like that happens, and might be the last. I also never tried meddling with my phone (rooting or the likes of it), so I'm pretty much clueless. I messed around with the phone, turning it on and off for a while, letting it run out of battery and charge it again, leaving it stuck on ASUS logo over night, to no avail.
Here are some things that I noticed that might help solve this problem:
1. After I connect the charger, the screen shows an empty charging battery along with the LED showing the red color (which means no battery). After 5 seconds, the screen turns on again by itself to show the true state of the battery, which is whatever % it is right now and the correct LED light (orange/green).
2. Turning on the phone makes the "low battery" buzz followed by a normal vibration. If it's charging, the "No battery" red LED shows.
3. I can turn on the fastboot mode by pressing Volume + and Power, but it only shows "CSC Fastboot mode!!! Long press power key to shutdown device". While on fastboot, my computer recognizes the phone is connected through USB, but I cannot access the phone's storage.
4. Pressing Volume - and Power does nothing besides restarting the phone.
My english isn't the best, so I apologize. If there's anything that I messed up and you can't understand, please do tell me.
P.S: Zenfone 5 Selfie is the same phone as Zenfone 5 Lite, but it is known by both names for some reason. Thanks for reading.

Exactly the same problem and phone I have here and Google research has been useless plus it appears this model phone has many firmware versions also
I have tried flashing firmware in fastboot mode but the ADB and fastboot tools won't work as it shows write protected as it appears bootloader is locked and am struggling with QPST also got so desperate to get phone working I even checked out some of those android repair software like DR fone then realised they want $70 USD and instantly removed the software haha
Hope we can get answers but seems like that maybe no one has solutions for this
