LG G4 – Smartphone has suddenly gone out. Now it does not turn on.

Now it has got me! :O

I have more than once failed my Google account to change in Chrome and suddenly the screen went black and the mobile phone has gone out.
Battery good 76% was last fully.
Cable plugged-no reaction.
tried-no reaction battery several times out, wait 5 minutes, back in, turn on
the power button for several minutes down-once the phone is up to the logo booted, but no further. Again identified-now no more reaction.

What else can I do?
From flashing and so I have not got a clue.


Have you tried a hard reset?


No. I do not know how the key combination at G4?


Have these instructions found.

Thanks, it read. But in any case all personal data is deleted.


Yes, that's probably as the hard reset.:(


Inga Lena, have you ever tried to connect the device to the PC? Maybe you can so at least your data (zumidest the images, etc.) save.


To my Lappi I can not connect (for good cause) the mobile phone
of my boys I do not get to.

Pictures I have just moved on Sunday all to the SD card, music has always been there.
But I have a Notitz app where I write purely ever small memory crutches and a Tagebuchapp where the recipe for my sensational poppy seed cake is. From both, I have no backup :(


Reset, as described, does not work.
The second confirmation is not accepted.
Now when I try to start the mobile phone, it falls five, six times in a bootloop and then go out completely.
Since only battery helps out.
One time it's kmplett booted to the start screen.
But then I wanted the SD card shove (it comes without the battery to remove) and as it turned out.
I wanted to copy the few important things on the SD card.


If you have bad luck, you have the same defect as I (defective board / loose contact). Then your data is gone anyway, unfortunately, :(

Was with me exactly the same: once booted up to the logo, then it was over (Nerd)

I would try the hard reset.

Do you still have warranty on the phone? LG repairs the free ...

Edit: OK, then helps probably just send in ...


I have researched just the Internet.
It really does not look good.


We here

https://www.google.de/amp/s/www.inside-handy.de/news/38795-lg-g4-bootloop-defekt-reparatur-kostenlos/amp?client=ms-android-samsung

is reported the cause is "only" a loose connection.
So it ought to be possible to save the data on the phone (surcharge) :?


LG will repair the affected units free of charge.
Yes, you can save the data. In addition there are also instructions on the Internet. From "put in the refrigerator" which helped for 5 minutes over "heating with a hair dryer"Has what helped 30 minutes to complete decomposition. But at the latest in the latter case it would then no longer be with "free repair",

What is worth to you more?
The device or the data?
Are your data may already be gone because you have tried the hard reset?


One can even try with herb burning at full moon?

I mean, often offer these workshops that carry out the repair, the data recovery on. (See W-Support).
My Gedankenweg was this: if now that the board, memory or CPU would be in the bucket, then the data is gone.
In case of a broken plug, it could work with the data recovery?
The hard reset was not executed because the second "Yes" was not accepted and has loaded as the phone once to the Home screen, my curly seen.

Try on, but that will not help. If a hairline crack in the board or a cold solder joint is the reason heat can certainly help, because by heat, the materials expand, causing an interruption could be closed.

But do not get too hot if you want to try it.

Experiment makes kluch!
The job I would in your place definitely try to install.


Not to is hot as warm?
I have an infrared thermometer. So I can check the temperature.
What point exactly?
About the battery? Under him? Left? Right?

The whole device.
40 ° C case temperature is not a problem. You can also go higher. To 60 ° C case temperature should also be more easily. But slowly and evenly heated and not permanently, but only briefly. If you turn off the hairdryer, the unit will cool yes again. For this, it generates heat at the start.


Ah! OK thanks.
Will I try afterwards.


Unfortunately, the test was negative :(

I tried three times with the hair dryer.
Now the phone is back to room temperature.
Maybe fridge?
But I have some concerns about the condensing water.
If one of the indicators change color, then it was.


Hallo Ingalena,

you are there actually turn went with the hair dryer? :O
I have the previously considered a bad joke.

The low temperatures at which you have hot blown your phone, should have little gepracht or nothing - this would then when short-term selective heats in the right place to be rather helpful. As a layman, I would but since not drangehen.

If you care about the device, then I advise you to not continue to experiment and to give the device to the professionals. The cold is as sure bring nothing - at least no positive effect.
