I'm very much new to this, so please take it easy on the terminology, and insults.. :/ Just to be clear ive never rooted this phone or flashed it or anything like that.
I was using my phone and the battery ran really low and it died. I went to turn it on, and it wouldn't turn on, so i charged the battery for a good hour. I press the power button and it vibrates, but the screen stays black.
after that i tried doing a hard reset, so with the phone in that black screen, i took the battery out so it would turn off. Put it back in, followed the instructions for hard reset from the VZW website (without turning the phone on, because i'm still unable to do so), and nothing happened at all. I gave it a couple tries and still nothing.
Then i took the battery out, put it back in, pressed the power button. I felt it vibrate again like last time. So in this post-vibrate state, without removing the battery, while the screen is still black with no power on, i did the hard reset. It vibrated and then now the 4 touch buttons at the screen illuminated, and the backlight turned on, but the screen itself was still black.
can anyone help me out??

When the phone is completely off. Battery pull. When holding down (Vol Down + Power). Does the HBOOT (white screen) appear or is it still black?

Do you get anything when you plug it into a computer? Any new devices that the computer sees? If not. Need to bring it to the Verizon store bud :/

I would say go to tje Verizon store and have them charge your battery. If it takes a charge and powers on then it prolly your port.

Last night i fell asleep and my phone died all the way, and now when i plug it in all i get is a lg logo then it goes away and then a dark lit up screen. ive let it charge for awhile now and i still get nothing, i cant get into cwm either.. the phone is unlocked and rooted and im running the base rom. Any help would be greatly appreciated.
Happened to me... leave it on the charger at least 3 hours and check it. The battery completely drains when you unplug the charger if you charged with the phone off. gl
Edit: If it still won't work, turn phone on and plug in charger.

This happened to me too. I completely drained the battery and it kept going into a loop (black screen, LG logo, battery screen). I left it plugged in and off and let it boot up.
FYI
This has happened to several people. I have confirmed through testing, even exchanging my phone 2 days ago that this is an issue created when unlocking the bootloader. Rooting does not cause it. Once the bootloader is unlocked, you can not get around this by re-locking the bootloader.
The workaround is simple. Either leave your phone on while it is charging or if you charge with phone off, unplug your charger and hit the power button- you will still see the charge animation running- this is what causes the battery to drain. All you have to do is power up the phone at least to boot then it is ok to turn off. You can confirm it worked by touching the power button again and not see the charge animation. Hope this helps.
Wow thanks so much for the reply and help! I've got it working now and I guess I'll just avoid it by not letting it die lol

well...
If you let it die all the way, its not a big deal. Plug it in, hold down the volume down button and the power button for 15 seconds, then it will work fine.
Threads like this makes this forum so great. Another potential problem to be avoided when using the phone.

I could use some help guys, if this thread isn't too old. I've searched high and low to the answer here and nothing is working. I've tried download mode, fastboot, recovery, reset, holding power down, plugging it in and unplugging it. I've pulled the plate off of the battery, tried LGNPST, drivers, etc. No go on anything.
The phone is still dead, and will not turn on. The best I've gotten is a solid red light after holding the power button for 15-20 seconds. Then after about 3-5 seconds it resumes flashing (alternating between the red light and the key buttons). If I continue holding the power button down it will repeat this, showing solid red and then reverting to flashing.
I can not get the screen to display anything, not even the charging animation, and none of my computers will even recognize the device. I've been messing with it all day and I'm stuck. If anyone can help me, at all, please do. I hate going to Sprint. Anything but that, please.

Some body, please help!
I've searched the forums of XDA and I've scoured the internet via google search and found nothing pertinent to my situation so I hope you guys can help! It seems I've hard-bricked my month-old HTC One. Never dropped it or got it wet.. Never even rooted or unlocked the bootloader.. it's completely stock. (I've been waiting very patiently for that 4.2.2 update to roll out for AT&T)
It just went completely dead earlier tonight as I was browsing the Play Store. I've tried to perform a reset by pressing the power button and down volume, but even after a full 60 seconds.. nothing. I've plugged it in the wall and no light comes up in the speaker grill. I've plugged it into my computer and nothing shows up.
Is there any way to fix this through ADB? Is there way to recover my data using ADB or some data recovery program on PC (or Linux)? Or is my best option to just take it back to the AT&T store and start anew? Thank you for your time/help XDA peeps!

Does any lights on the buttons come on ? Will the red light in the speaker grill come on connected to the charger?
I have read somewhere if you put the phone under bright lights then try to boot into the bootloader it will work, Sounds crazy I know but it works for some. Past experience on the HTC is if the battery is super low , like down to 30 % or less it wont come on. Have you tried to connect to a charger and leave it for a few hours then try ?

Nope, nothing.. No lights in the speaker grill at all when plugged in. I came across that light sensor trick and held my phone a foot away from vanity lights in the bathroom (should be bright enough right?) and tried to boot into the bootloader.. nothing. My battery was at about 60% when it did this last night. I tweeted HTCUSA and they told me to do a similar thing (put it on wall charger for a couple hours) and yep still nothing.

I know this sounds stupid, but is the cable good ? The one that came with the phone and charger? Have you tried other cables? Do you have adb set up right on the PC? Tried any adb commands to boot to bootloader? Last resort I can come up with. Have you run an RUU for your model and carrier?
same prob as OP
this same thing is what i am having a problem with this is the second time it has happened to me the first time it froze and i held the power button to turn it off and after about 10 min of holding various button combos it finally came on after holding the power button for a good 5 min.

Usually for the HTC ( well my experience). Holding the power button with the volume down button at the same time for an extended time, the lights at the bottom will flash for about 13 times continue holding the volume down button and release the power button. It should boot into the bootloader. From there, reboot, boot recovery or boot fastboot. IF this doesn't work, I have read in the posts here to hold the sensors under bright light and do the power down and volume down . If just rebooting the phone only hold the power button down. The lights on the bottom will still flash about 13 times and the phone will vibrate then release the button and it should reboot.
If the adb is working there is a mod called Regaw ModRebooter, which when installed sits quietly on the task bar or hidden icons. Just clicking will reboot to bootloader, recovery or reboot or power off the phone. I find this easier than using the buttons or just use ADB commands. Phone must be plugged in to PC to work though

I had a similar issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps, last time it happened after a reboot from an update and still having plenty of battery left.
I tried putting it on the charger for a whole day with no result , put it back in the box to return it , decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and it worked again magically indeed, functions totally restored till this day.
Hope this helps a bit

If it's like the Z1 Tablet you could try a complete power down by pressing the volume up/down, and power button for several seconds, then try to do a recovery via the Sony PC companion (so long as you can get into flash mode), if it works you'll loose all data, but it's worth it IMO

I've got something like this going on too. Plugging it into a blackberry playbook charger seemed to give it a charge when the OEM charger wouldn't work. It came back to life. I've also noticed that the tablet won't sleep properly while charging. I plug it in, hit the power button to sleep, and it wakes it self as though I plugged a charger in. And so I cycles dimming the screen to sleep and then seconds later like u tap the power button to get the screen to wake. Something s definitely wrong.

I'd the same on my SGP511 yesterday when rooting failed. Just charge for an hour using Sony charger, then press POWER + VOLUME for more than 60 seconds. It vibrates three times and resume from death. Cheers!
It seems like some of these boards may be failing. I think this issue is related to the screen not powering off while charging issue. Users are reporting that Sony is repairing the devices by replacing their main boards. I wonder if there is a known issue with z2 tabs that Sony is aware of.
My z2 tab has both of these problems. I flashed a factory ftf to it and it still had the problem. This is what led me to believe that it was hardware related as it didn't used to do it running cm11 or stock firmware.
I had this happen to me once or twice, though in my case I could recover via power + up/down (can't remember lol) .
In the end my tablet developed other symptoms (namely inability to magnetic charge, and screen stays always on when charged) so i sent it off for repair and they replaced the motherboard.
Hasn't happened since, though I only have had it back for a few weeks. Touch wood.

Does replacing the motherboard mean fully stock and locked boot loader with present DRM keys?

Yep as in these tablets the flash/CPU/RAM etc. is baked into the mobo so its more or less getting a new tablet internally.
to my shame I updated it without remembering you can only root the older firmware which it did come with ROFL.... oh well the only thing I use root for is adblock

Can't you just use flashtools to downgrade your tablet back to the rootable 4.4.2 firmware?
I managed to downgrade my xperia z2 4g tablet with flashtools application.
Only hiccup was that i accidentally put my tablet in bootloop while i tried to downgrade it, after that i just rooted and installed dual recovery. With that dual recovery i could flash pre rooted 4.4.4 and so i still have my drm keys and ps4 remote play app.
Hi I'm really hoping someone can help me. I received a Sony z2 tablet spg521. I was told it was new but it would not power on or charge, and the charge light would sometimes blink red. Well I got the fixed or so I thought by doing a soft reset and then pc companion...sounded simple but spent a couple days trying to be successful. Sometimes my computer would recognize it sometimes it wouldn't.... Any way I finally got it out the blue dont know what the difference was I was just happy it finally worked... I then fully charged...yadayada and used it flawlessly for about a week... It would turn on and off, battery held charge like its supposed to, everything seemed to work.....then I went to power off but hit the restart by mistake....no there is no power again and this time it will not do a soft reboot.....no light ever....computer will not recognize ever....I have been trying off and on for a few days.....among-est my research to try to correct it seems like this is very common....when i shut it off the battery was over 50%..so how can something work fine then just die like this??? Ive seen that sometimes with sony if you disconnect the battery and the reconnect this will work... does anyone know? does anyone have any advice before I take apart this cherry tablet to try the battery thing???
I would really appreciate any insight as I have fixed many of my own problems and for others from advice on this site. Have a wonderful day and thank you!!! :silly:
ok today i tried to use flash-tool that Ive read about on this site....when it asked to plug n device computer recognized it and red light came on, but flash-tool did not recognize it....torn between letting it set and seeing what happens or trying to get the flash-tool to work, I chose the flash-tool...bad mistake when I went to try to reconnect and see if the FT would see it..it was no longer recognized by the computer and no light but computer did say USB device not recognized and not installed correctly.....now I already have the right drives so now Im really confused..tried a couple more times with same results and then once again nothing...no light no soft reset no recognized at all by computer not even not recognize USB....so disappointing loved the tab but this is insane that sony does this as its not user error but sony error and they dont even man-up and try to make it like you dumb or something....will try again..when i calm...
reset the device by pressing power+volume(up or down) for several seconds. It seems like a toasted one, possibly caused by putting magnetic charger on wrong polarity.
Thank you yes Ive tried all kinds of resets I have found...I agree seems fried but I would not know how. I have not used a magnetic charger...only the regular sony one that came with it....
So last few days I have tried off and on again....now computer recognizes by making noise when connected and disconnected but does not show up...PCC does not recognize it.....flashtool says its connected in log but when it asks for it to be plugged in it never leaves the screen telling you how to connect....when I try to connect the charge light comes on for about 4-5 secs then turns off....still no vibrate when try to reset still no light when plugged to a charger.....I want to get another one but I am scared this will happen again....gonna chuck this one as if time is money then I have well exceed the worth in time... I only got this because some time ago a sony z1 came my way and I so love it...i recently upgraded to z3.....i have a lg pad but screen got broke so I got the sony tab....maybe Ill just fix the lg

Mine is kinda toasted and this is how it works. Whenever I have a problem, I have to reset by pressing power + volume up, as soon as I hear three vibrations, I turn it on by pressing power button. Otherwise this tablet will just repeat sony logo and no boot. If you have bought one "NEW" make sure to return or replace it. If you want to enter fastboot mode, repeat the resetting routine and pressing power button to turn on, but also right after that or even simultaneously press volume up to enter fastboot mode with usb cable inserted, or volume down to enter flash mode. either way, your unit is toasted and sony sucks.
Well, I have the same problem, and isn't fun. Just very extreme rare cases it turns on the screen charging the battery, but doesn't turn on sadly
I did a happy boot today after 3-4 months off with several times trying turn it on, and did all the tricks from all treats about SOD
Last weekend I did a full charge from deep red to green light and battery animation on screen at start, but no luck.
I put it back in the box
This weekend I got some visitors, one of them asked about the tab, told him it didn't work and showed to him
Pressed the power button and to my WERY BIG surprise, it vibrate and turned on as nothing was wrong
The battery was only 54% after one week off. it received a update (264) and I installed as normal, turned off and on again as normal and happy I was
