So, I had to replace the screen on my phone because it was cracked. But not after putting it all back together, the phone just boots loops. I am trying to follow the guide about unbricking your phone but I am unsure about getting into download mode. I hold down both volume buttons and plug in the usb into the computer, but noting happens except the phone just keeps boot looping. How do you tell if phone is in download mode? What does the screen look like?
If you get into download mode, you can't miss it. It is pretty obvious. To get your phone into download mode, shut off your phone (Hold power button for 12 second), wait 2-3 sec, press both volume button and then insert usb cable.
Hmm. Seems like my problem is something else. I can't get in into download mode. I cant even get the phone ti turn on if it isn't plugged in.

Could your battery be dead? Getting to download screen is a bit tricky as far as the timing is concerned.
USB should be already inserted, otherwise phone will just boot when you plug the cable in.
So usb pluged in, next turn off the phone via power button, now hold both volume buttons + power, should work.

^this has been my experience as well. Turn phone off. Insert USB. Wait for charging screen to flash on and disappear. Then press and hold vol+ vol- power until Download Mode screen flashes on, then release buttons.
First of all when in download mode you'll see a box displayed saying "download mode" it's hard to miss even you try to.
Here's how I did it. Instead of trying to push both vol + and- , press the middle part of the volume rocker. And press power button at the same time. USB cable can be plugged in advance or can be inserted later on. Only advantage of plugging the USB later is it gives you a proper grip and reassurances you've pressed the button combination correctly. Note that the phone will look for a USB presence before booting to download mode..hope this helps

So my galaxy nexus' power button won't work. At first I thought I had bricked my phone when it shut off and wouldn't respond to anything. Yet when I plugged it into a power source it showed that the phone was charging. And when I swapped batteries it would accurately show that the battery was charging and it would charge the battery. So I bought a jig and plugged it into my phone and it booted it straight into Odin Mode (I did not have to press the power button it just did it) and now my phone is in Odin Mode but I can't press the Start button well b/c my power button doesn't work. I have tried the jig with different batteries and I have tried powering the phone on without the jig, to no avail. I am assuming this is a hardware issue or is there some software issue that causes the Power Button not to work? And if it is a hardware problem is there an easy fix?
is that I have tried the combo volume up and down and connect the usb does not work, there will be another combo aya not tried?

You did hold the power button too right? I'm asking just to make sure, not trying to be a smart mouth. Try hold power + both Vol. buttons without the battery, and plug in the usb cord to computer (with the other end attach to the device already of course). If that works, you can put the battery back in.

I have the same problem, I was upgrading my f240 to KK but it stucked at 60%.
Now I dont know what to do & my f240 is stucked on 'download mode'
What should I do?
I have a V500 that won't boot, and doesn't appear to charge either. Here's what it will do:
1) When plugged into a mains charger, flash up the LG logo briefly. I don't need to press the power button for this to happen.
2) When plugged into a mains charger with both volume keys held down, boot into download mode.
If I plug it into a USB port it won't power on. It will briefly be detected by Windows but not as any useful device. I cannot get it into download mode when it's connected to a USB port, and if I do (2) then unplug it powers off.
My powered USB hub has an indicator light. With the tablet connected, whenever I press the power button this light comes on for a second or so. If I connect the USB cable whilst holding down both volume keys this light also comes on, but the tablet does not go to download mode.
I have already changed the main flex cable in case this was the problem.
Does anyone have any suggestions?
Try it with one of the USB plugs at the back of the computer.
I've got devices I can transfer files on and off via the hub built into my monitor but if I want to do anything lower level I have to use a USB port on the computer.
I have finally been able to sort this.
I'm not sure precisely what was wrong. I changed the internal USB flex cable and this made no difference.
Next I bought a switchable "data/charging" USB cable that was very useful in diagnosing circumstances where it would enter download mode.
After much messing around I found I could plug the device into a powered USB hub that wasn't connected to a laptop and enable download mode, then connecting the hub to the laptop it would stay in download mode and allowed me to reflash it back to stock so I knew the software was at least okay.
It still wouldn't do anything other than show the initial bootloader logo though, and this only when plugging in a cable. Pressing the power button did nothing.
Since it was still open, I disconnected the battery. Tried powering on with the cable connected, nothing. Left the cable connected, connected the battery - bing! We have life.
It's now bootlooping but it's playing animations and making sounds, so I'm hopeful I can factory reset the device. The power button works at least

Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

Great success! Device is working
Clarification, please
If you have a V500, explain how you can hold VOLUME button simultaneously in UP and DOWN position. It's just one rocker button, but you keep referring to it as 2 separate volume buttons. This goes for madscout quoted solution as well.

Using two fingers. It's one rocker but you can hold both buttons down at the same time.

I think we're not on the same page as far as my query goes. Forget the POWER button - it is not an issue. Because VOLUME button is a rocker it is impossible to hold down VOLUME UP and VOLUME DOWN positions simultaneously as madscout solution advises: "Now press and hold the power and volume up button while keeping your hold on the volume down button". Such trick is impossible even with 3 fingers, because the Volume rocker can be pressed and held either in Up or Down position. Madscout wants us to keep it pressed in both positions simultaneously, the crucial phrase being "while keeping your hold". Now, do you get my drift? And explain to me what madscout meant? Thanks!
My V500s allow the whole rocker to be pressed in at the same time. It's not a true rocker.
If you open the device up, you will see two independent buttons.

REALLY? That's a surprise. Thanx, bro. Sneaky LG put in fake rocker button.. Meaning, that madscout's solution requires 3 fingers - 1 for Power and 2 for Volume.
Or 1 finger only for Volume if it's pressed exactly in the middle. Crazy world.
Any help? Similar situation at my Gpad - usually after initial animation is powered off. If I make factory reset i can start device, i can adjust some setings, but in a few minutes it is switching off. V50020F and no root is there.
I was using the phone and hit the power button for sleep. Then when I checked it 1 hour later it will not power up. It there a way to reset the phone, this is why I hate phone you can't take the battery out of. But it is just a travel phone and now I am stuck.
Any key combinations or anything! ??!?!
You should be able to just hold the power button until the screen lights up. If that doesn't work hold the power button while connecting the usb c cable to charge it
Power button+volume down for 30 seconds.
Most likely the qdloader 9008 bug.. Volume down and power for 60 seconds always fixes the issue. Either that or let it discharge on its own for a day or so then plug it in and you're good to go!
Hi !
Have anyone sorted this problem with suggestion ?
Mine is getting warm when charging (warmer next to the power button area) but still no led indicator or power ON !??!
