Phone Not Booting - LG E988 - LG Optimus G Pro

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???

Help me devs! Bricked?

I recently completed all of the steps for a one click root of my epic and attempted to boot into CWM mode for the first time and now all I get is the samsung screen. No vib, no blue light... it just sits there on the samsung screen. I've tried every button combination I can think of and nothing happens. I think i may have created a paper weight. Can anyone help? Thanks in advance for you time.

Hold the power button and the volume up button. It'll reset, continue to hold, it'll boot into recovery.
You are not bricked, probably a bad flash or cable. Redo the one click and should all be fine

The community would love to help you but you have to let us know if any of the above fixes have helped? Do you know what a jig is just in case?
Just a bad flash, happened to me once. Boot back into Odin (Hold power and volume down) and redo the one click process again. Make sure nothing moves the cord or try a different one.
Hope it helps.

I did try the suggestions above. I apologize, it seems i wasn't clear in the OP; I get the samsung screen no matter what I do, all button combinations. And when plugged in to the PC it is not recognized.

Your phone is not seemingly bricked.
Try the button combinations mentioned above but hold for like 20 seconds.
your NOT bricked.. just soft brick.. like suggested, calm down and hold volume down and power until it reboots into download mode again.. if its stuck at samsung logo get it to turn off by a battery pull or something and start over fresh. hard brick wont have a logo it will just be a blank screen and a solid blue led and wont do anything at all

Sometimes it can be a pain in the butt to boot into recovery or download mode. Just continue holding the button combination until it enters download mode. It might reboot and go back to the Samsung splash screen. Just hold Volume Down and Power until you are in download mode. Do not release the buttons until you have successfully entered download mode.

I held the buttons for 65 seconds... How long should I expect it to take?
It really shouldn't take any more than 10 - 20 seconds max.
You must be holding it wrong... as Steve Jobs would say.

I'm all set. Now I'm testing roms to see if I can screw it up again . There are too many "epic" models... I have the sprint Epic, the one w/ the slide out keyboard? Is that the OG version?

Yes, that strategy works, but it is not good for the battery. No battery should ever be discharged 100%. Even modern batteries could have issues when completely discharged. Batteries that are completely discharged could leak and cause damage to your device.
If you get stuck in download mode and cannot get out, then try and find out WHY you cannot get out. Something went terribly wrong like possibly the application is not compatible with your device.

Yes...I too accidently went into download mode and I discovered that long pressing the power button worked. I think holding volumn up plus power button will help as well. Or plug up to computer and run recovery using odin.

What happens when you get into download or recovery mode? Does it do the same? Sounds like you may have a stuck power button

i can get to recovery mode and all, i tried wipe cache on

yes, i think its on power button, but after i searched how to fix it
most people will just slam their power button to a hard surface
to fix it.
Do you use a protective case?
Sounds like a physical thing on the power button...

No I mean if it reboots as well after 10-25 minutes in recovery or download mode like it does when booted normally. That would confirm that its likely a power button issue

Are you using GT-I9500? If so this is the wrong forum.. But what I would do is backup all my personal files, important messages etc. flash stock firmware with Odin, reboot to recovery and factory reset. That fixes many problems, but I don't know somehow I keep thinking something is up with that power button.. Or you could try what you said earlier and smash your power button lol

[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

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.
