Wont turn on!

Hello!
I dropped my LGOG E975 and the screen has cracked. The upper half would still work. But i could not turn the phone off. So i let the battery run dry. When i came back from vacation, approx. a month after, i sent it in to change the screen. It got changed, but now it has another problem:
It wont turn on! At the store they said they could not get the phone to boot. I took it to a charger and while holding the volumebuttons it showed the LG logo for a second, then blinked red a couple of times. This happend twice. Now if i hold the power button for 15 seconds and plug it in, it will quickly blink a red light.
What to do? I suspect it's something with the software.
FIY i unlocket the bootloader, rooted and installed a recovery. Dont remember which one tho'.

Update:
I can now enter fastboot or download mode. But the phone wont be found by kdz. flashers.

Try to access recovery from the fastboot screen, pushing 2 times volume down then power.

The phone turn black, blink red once and thats it.

As a sidenote, i can only put it in fastboot or downloadmode after i hold the powerbutton a while before plugging it in. Else the red LED wont blink.

I have no idea then
Have you tried to put it in fastboot without plugging it in? Volume down + Power button when the phone is off.

No response from the phone. Can it be a batteryproblem since the red LED flashes shortly when plugged in and entering fastboot/download mode or trying to open the recovery?

Maybe. Leave it charging for a while and try again.
My father always lets his phone die out of battery and he leaves it off for a while like that. When trying to power it back on, or when plugging it to the charger, the led flashes just like you described. It's not an OG, but it may be something similar what's happening to you, since you said you left it for quite some time turned off.

Okay, i will try to leave it over night. It will sit in the charger for 6 hours before my next check.

Try to upgrade/recovery with LG support tool in download mode

It would still not turn on. Tried multiple chargers and leaving the phone in for a long time. I got a new battery on the way.

Sometimes it helps to hold the power button a bit longer.

I held the powerbutton down for multiple minutes. Still no response. I ordered a new battery from Ebay. Hoping this would fix the issue. The battery have a expected delivery this week. Will update the thread with the results.

Hope it works :good:

I tried everything. Really. Every possible combination of buttons, chargers and cables. The phone would only give a response when plugging it in. So i expect it to be a charging problem with the current battery.

what was the outcome with the new battery?
im an currently experiencing an issue that sounds much the same as this, difference is that i was using the teenybin software and the HS shutdown halfway through the update, and now will not do a thing other than blink the RED LED when i hold the power button down whilst pugged into charger
also to mention, the battery life on the HS prior to this was reasonable..

HELP! Tab S 10.5 is either frozen or won't turn on

So I've been using my Tab S for a minimum of 3-4 hours a day since I got it in Feb.
It is the Tab S 10.5 32GB version from Best Buy SM-T800
I've never dropped it, scratched it, etc. I've been VERY careful with it.
I installed Iron Rom on it in March (before Lollipop came out), and besides one freeze per month, have had no issue with it (I've also never updated Iron Rom as it never had an issue).
This morning I used the tablet for an hour while it was plugged in (and at 100%). I then unplugged it and put it on a table. An hour later, I went to use it, and the screen stayed black when I pushed any buttons!!
So I tried holding down the power button for 30 seconds. Nothing. I tried plugging it in. Nothing. I tried holding down volume down and power button for 30 seconds. Nothing. I tried holding down all the buttons for 30 seconds. Nothing.. I tried holding volume up, down, and power. Nothing. I tried holding volume down, menu, and power. Nothing. I tried holding volume up, menu, and power. Nothing. Then I repeated the above over and over. NOTHING!
I even waived magnets over it.. (I read it on the internet).. Nothing
This tablet is my daily driver. It won't turn on, it won't show me a charging screen. I'm freaking out! There is no physical damage to the tablet, no one else has touched it.. I'm freaking out man!!
Any suggestions before I jump out the window?

Hi, I think someone had this problem a while back. No matter what he did, it didnt seem to turn on at all. It turns out, it was some sort of hardware problem and even though knox was tripped, it was repaired free of charge. The only thing I can think of is sending it to samsung or something and say something like you were trying to update through kies and this happened ao you can get it repaired since its not your fault. I am leaning towards that this has to be an hardware problem since someone (XDA user FormeriPhoney) had the same issue with his. Hopefully it goes well with your Tab S!

Argh.. I talked to Samsung.. They said I would need to send the tablet to them and I would get it fixed/replaced but it would take 2-3 weeks. They have no advanced warranty to send a replacement out first.
The other (and more scummy) option is to go to Best Buy, buy a replacement, and then return this one as a DOA. It would save me 3 weeks of being without a tablet..
This sucks

Try POWER + VOL DOWN.
Hold for at least 30 secs.
If not you may find after a day or so the battery will fully deplete and then start charging.
Do you get any response on the pc when you plug it in?

I did that
Held it down for a few min
Samsung chat had me plug in the tablet and hold down power for a minute
Didn't work
It's unplugged now and on a table.
I'm seriously considering the best buy option
Argh!

Oh.. And no response on a PC.
Yeah. This sucks. The only good news is that I actually backed up a lot to the external memory card last week as I was planning to go lollipop soon. The bad news is that all my customizations and other stuff is not saved (book marks in books I'm reading, etc). My titanium backup is from the first week I got my tablet.
But this is exactly why I won't get a phone without an external memory card. I would have lost everything.

IT"S ALIVE!!!!!!!!!!!!!!!!!!!
I woke up this morning,, resigned to no tablet.. still debating on going to Best Buy and getting a new one.. But I have 12 models coming in today for auditions.. So really don't have time.. But I NEED a tablet for notes with these auditions.
I walk over to the tablet laying dead on the cable.. and try plugging it in... and suddenly.. 0% comes on the screen.. it's sooo beautiful.. I want to make out with the tablet.. My heart leaps with happiness..
I turn on the tablet.. and it boots!!!!! It gets into Android.. and Nova Prime pops on the screen! But.. just as I couldnt get any happier.. it shuts down... It doesnt like booting at 0%.. So I wait another 3 min, half breathless... 1%!!! And I boot again. This time it sticks and I'm able to boot successfully into Android.
So here is my question. WTF happened? How do I avoid this?? Not being able to do a hard reset is some really mess up [email protected]#$%, If I was on a plane or other kind of trip, I would have been pissed... Let alone the wasting of literally 2-3 hours last night trying every single button combination for 2-3min at a time.

I'm surprised hard reset didn't work. I'd try it now it's working just so you know what to expect when you need it.
It may just be a one off. My tablet went into sd card mode once for no reason and that scared the heck out of me. I couldn't do anything. Left it overnight and after the battery ran down it started charging and then booted.
Never done it since.

Yup. Holding down the vol - and power after 20 seconds rebooted the tablet.
I would kill for a hard reset pinhole in the tablet.. Or a faster way to quick drain the battery.

Does the microusb port supply power when the tablets is turned off, if it does connect an usb device that will drain the power faster, like an portable hdd.

I've never known the hard reset not to work, no matter what state the tablet has been in and I've bricked mine God knows how many times.
Only when it dropped into sd card mode did it not work.

check my thread.

pixel wont turn on

hi guys
pixel just shut off all of a sudden and now wont turn on. pressing the power button for 10 secs does nothing. any suggestions?

Is there any physical damage, were you rooted, unlocked, etc.? This info will help get your problem solved, but my guess is that you need to RMA it to Google.

i bought this phone off someone on swappa. according to him, its never been rooted. didnt see any physical damage on phone.

Try holding the power button for a minute or two. If nothing then try to get your money back. I'm not sure how that works on swappa but you should have some kind of recourse. Thing sounds dead from what you're saying.

try pressing 3 buttons together. if nothing works after 1 minutes, you will need RMA your pixel.

it happened with me as well, no screen, but phone get warm and i can feel that vibration as well....bought from someone here in Brazil, and i really dunno how to start to ask for my RMA
can someone help me??
i think it will be hard to fix, because there's no bootloader....

If you search the net you will see that this issue is affecting about 1% of Pixel XL users. The only thing it seems is to RMA the phone. I hope you had luck returning yours on Swappa.

My Mix2 won't turn on anymore (white led still blinking)

Hey everyone,
I purchased a Xiaomi Mi Mix 2 about a year ago from a chinese website. So far it has worked great. I purchased another phone not to long after and gave up on the Xiaomi, because 2 phones.
After moving to a new appartment, I found that beast in a box and tried to turn it on in order to give it to some family member. Nothing would appear on the screen!
When I plug it on a power source, the led at the bottom on the screen blink once per second. Tried all the possible combination of buttons (actually, only 3 buttons, volume up and down and power) but it won't budge. Any combination of buttons will make the phone led blink 6 times 1 second and then pause for 2 seconds , and redo it in loop.
I tried plugin it on a computer, nothing happens.
I searched Google (even went to page 2!) but most of the problems relate to flashing the ROM and bricking it that way.
I was hopping someone could relate or help me find a solution before throwing that magnifient piece of design forever
Thanks in advance guys
EDIT: I left it plugged on a power source from 2 different charger more than 12 hours each.

Maybe it is completely discharged. Leave it pluged in the wall charger for a while, then try to turn it on.

When you plug your phone into a wall outlet does anything come on the display even very briefly? When you plug the phone into a wall outlet normally a screen should display with the battery level before it goes black again. If your display just stays black you might have a hardware issue. If you hold down the power button and volume up at the same time that should boot your phone into recovery. If you have a software issue normally your phone will still boot into recovery.

Get a new battery. after one year he will probably be dead.

Even if the battery can't hold a charge I would think the display would light up when the phone is connected to a wall outlet. The Mix 2 also came out just 9 months ago. That seems too quick for a phone battery to completely die.

Could you try to press the power button for about 1 minute ?
That did the trick when my old Zuk Z1 got discharged too deeply...
Also try to charge it with a 1 amp charger if that hasn't been done yet.

Help! Pixel 2 XL Won't Turn On

Hi everyone,
I'm hoping for some help with my Pixel. I was charging my Pixel overnight (though it was at ~65% battery) on a battery pack a couple nights ago, and when I woke up the phone was turned off. Nothing I can do now will get it to turn back on. I've tried multiple chargers (including the OEM), leaving it plugged in for a long time and then trying to turn it on, turning it on while holding power + volume down, etc. My PC will make a sound when I plug it in, like it recognizes a new USB device, but then it won't show up as a device.
Any ideas on what to do about this or what could be causing this issue? Currently phoneless so any and all help is hugely appreciated!

Holy crap! Almost sounds like your mother board went kaput! If you can't get into recovery or bootloader mode to do a factory reset, then about the only option as I see it is RMA. You certainly have grounds for it!

Something similar happened to me couple of month ago. The phone was on the charger and when I wanted to check it I noticed it was switched off. I could not switch it back on, tried to put it on different chargers, pressing different button combinations along with the power button, nothing helped. I then plugged the phone in to one of the usb 2 ports in the pc, used an Anker usb A to usb C cable. I could hear the sound the pc recognized it, then pressed volume up, volume down and power button for about 15-20 seconds. The phone switched back on... Since then (touch wood) hasn't happened again... Worth giving a try...

Did you have Google replace them under warranty? What was that process like?

Same thing happened to me once. I was sh**ING bricks because I bought my phone from eBay. Reached out to Google Support and they gave me similar instructions. I had to hold volume up and power for about 20 seconds and it finally booted.
