Won't turn on - LG G7 ThinQ Questions & Answers

It's stuck on a screen with a circle and a white question mark inside, flashing every half second or so.
I have tried holding the down volume key and the power button but it doesn't work. Returns to the question mark every time.
This happened after I restarted it yesterday because I noticed the battery percentage wasn't dropping and I thought it was a bug or something.
I have charged it all night but it's no good.

It doesn't show up on LGUP. Seems like the phone is not registered as connected.

Hi I have this very issue, I've just swapped the screen and the battery out (the battery was ruined during the screen replacement)
Any ideas how to fix it? Could it just be a totally dead battery?

That's a good start, the phone is stock and locked ....not an unlocked bootloader ?

Phone Not Booting - LG E988

Guys I am in serious trouble. While restoring EFS. After reboot My phone not booting up, I tried to hard reset but no luck, I tried to put into download mode but it is not booting. Just dead black screen.
Any one have an idea how to fix or put into download mode or reboot.
To put it in download mode, hold both volume buttons for like 5 seconds. Then plug it in as you are holding them. Don't release the buttons for a min... Or until the "Download Mode" screen appears. Hope this helps

If you can't get into download mode then you are hard bricked and the only way of solving the problem is probably JTAG. Are you sure the battery is charged??? If you charge your phone does the screen turn on???

was an odd thing phone was ringing and shut off, had several calls from same number i had rejected and when i called the number from a landline said the number was not active
i do appreciate the help though was seeing if there was something i hadn't thought of trying already
Similar thing happened to the display model at a local Verizon store. They said after hooking it up it shut off and wouldn't power on, all you get is the battery charge logo and the Orange light. Went in planning to buy one...decided to wait a bit...

[Q] Not booting, or charging after root

Hello
Some days ago, I rooted my Samsung Galaxy s4 mini succesfully and it was all great, untill the SU binary had to be updated. I had a custom recovery so I tapped on the custom recovery option and not normal. I had a little battery. The screen went off. It got back and that was it. It was not to boot ever again. No matter if charged or what. I tried to boot to recovery. I took battery off, held upper volume button+home+power button and got battery in while I was holdin them. I even tried without holding the power button. Nothing. Plugging it in charger won't even turn the screen on.
Is it bricked? PLEASE tell me no. Is there ANY way to fix this? Do not care about reseting or what. Just wanna fix it. In addition, I do not know if its useful but, I had swap space too in my SD card. But is not booting in any way with SD out either.
HELP. Thanks in advance ^^
Oh and if I can't fix it, is there any way I could pull my data from the internal?
Thank you

Can you enter download mode? Home+volume down+power until you see the download screen...
If it's powering on it should be salvagable..

Ok, this may sound strange but try it... in a dark room, try and power the device on. Does the screen blink at all? It may power on and display a black screen so it may be difficult to see in day light. If it does the battery may be fine..
If it doesn't do anything it may indicate a problem is with the power source - your battery..
Also, when you're trying to enter download and recovery you're keeping all buttons held down aren't you? I've made that mistake many times myself so I know how easy it is to forget! (I normally reboot to recovery from the OS using the developer options).
I'm suspecting it's hard-bricked. Then this may be the only help;
- Buy a USB-JIG online
- Make sure that the devices battery has charged (even if it doesn't show charging animation)
- Remove your battery
- Plug the USB-JIG inside your phone
- Wait 3 minutes and put the battery back inside
- Wait 40 seconds and the "download mode" screen should appear

I'm intrigued by the jig mentioned above!
Personally, my next step would be the cheapest phone battery I could find.. that would help you diagnose where the phones at the quickest. If 2 batteries won't turn your phone on then it may be game over... but for the sake of a few £/$ it's surely worth a shout!

If I were you, I wouldn't go for the battery first.
Buy a £5 USB-JIG, it will help you for sure. Keep the phone connected to the mains for 2 hours, even though there's not thing that's showing that's connected. Then remove the battery for 30 seconds, connect it again, and connect the USB-JIG. Bam, you're in download mode ready to flash a firmware with odin.
If the phone didn't boot after connecting the jig, then buy the battery because then you have a positive indication that the battery is the problem for you.

To summarize, it honestly does magics and makes your screen available again.
It has 3 resistors in it. And it somehow boots the phone up.

Just search for a USB-JIG on ebay. All of them are compatible with the s4 mini. It is approximately €5.

does the screen come on at all? Sounds like Sleep of Death to me. Most likely related to the tab not having enough voltage to wake itself back up. I believe there is a fix out there for this, but i would ty booting into DL mode, or recovery and see if you can get it fixed. Or you can force a reboot by holding in power+volume down+Volume up.

already did try that... I'm quite sure is Sleep of Death, I couldn't boot in download or recovery mode, it didn't charge and so on.
The thing I did that resolved the issue was opening the tab, by detaching the back cover and unplug the battery connector for 30 min.
That fixed it, but it's for sure an unpleasent fix...
thanks for help though!
