[Q] How to know when phone is download mode? - LG Optimus G Pro

Just wondering, I'm attempting to flash back to stock, but I have no idea when my phone is in download mode.
Also, how do you get there, as in what buttons do you press?

I removed battery, held both volume(in middle of +/-) and power button together then plugged cord into phone and waited for download mode to appear on phone. Then I put battery back in phone.

Epic Download/Recovery mode with Bad Power Button?

I have an Epic 4G with a power button that will not respond, period. Phone is off and responds to the charger/usb cable being plugged in and all other keys cause the phone to "light up" when charging, but the power button istelf does nothing.
So, assuming the power button was bad, I ordered a new power button assy and installed it. It too will not work. There appears to be no physical damage to any of the ribbon cables, connectors, or boards inside the phone. The phone was Manufactured a month ago, so is fairly new and has gotten little use.
The phone's esn is bad, and my intentions were to flash it to cricket for a customer, so sending it Sprint is abviously not an option. Sending it to Samsung is also not an option since the phone has now been disassembled.
Is there any way to get the phone to "POWER ON" with any other button combination?
I have tried:
Plugging in USB Cable while holding 1 key: Does nothing
Holding VOL-DN + Camera + PWR while pluggin in USB: Does nothing
The phone only responds with the charging indicator (which the battery is now full).
Is there any other way to Force it into Download or Recovery Mode without a working power button?
Any help/advice would be greatly appreciated. Thanks!
I know a jig will work for download mode but I'm not too sure about recovery other than using rom manager to boot into recovery.... worst case senerio sell it for parts the screen etc etc.
I remember hearing someone using odin for turning the screen on search about it?
Would be really cool if you could remap the power button to something else but I know certain lockscreen apps or ROMs will allow for phone to be awaken by the camera button.

Hold 1 and then plug the phone in to USB. It will then boot into download mode. For recovery, hold vol down, camera, and then plug into USB.
Edit: just read that didn't work. Try taking out the SD card and battery and letting it sit for 2 hours then try again with the battery and SD out.

I was able to get it to boot up by plugging in the USB cable and unplugging it at the right time. But the phone doesn't respond to the slider, power button, or 2nd "click" of the camera button. However 1st click of the camera button and volume buttons work.
while playing around with it after about 10 mins the display switched itself to landscape mode and the keyboard backlight comes on, as if it has been "slid" open. If I slide it open and closed, it remains in that mode, as if it still thinks its slid open. However not all the keys on the keyboard are responding/working, but most are.

hmm, the problem isn't progressive, so it not getting better or worse. The only thing I can think of is a bad connection or the replacement Chinese cheap ass power button assembly is also bad.
the phone is only a month old.

When you get it to notice the keyboard slid open, pull the battery or turn it off then hold 1 and plug the phone in? That's my guess

I replaced the power button assy with the stock one from samsung knowing the power button is faulty, and got the phone to power back up jigging the usb cable in/out until the samsung logo appeared. The slide open/closed works perfect, and all other buttons and keyboard keys work fine as well (except the power button of course.)
This would leave me to believe the cheap chinese replacement board from ebay is bad to begin with. So ill have to order another one from a different seller/manufacturer.
I had installed the rooted UrbanPrecision X2 Gingerbread EI22 ROM with CWM Recvovery 5 before the power button failed a couple of weeks ago, and its working fine, but Id like to install the stock EC05 GB Rom to it through odin/recovery.
So my next question: Is there a way to emulate the power button with an app or something? Or enter Download/Recovery Mode from an app within the phone without using the power button?
Thanks again.
maybe this?
If worse comes to worse you can try this http://forum.xda-developers.com/showthread.php?t=1274999 which allows access to the most basic parts of the phone from what i understand. The only issue is you would have to use the ressurector every time to boot. also if you get it to boot with out this you can just use adb commands to boot into recovery and download mode if its powered on. The commands are adb reboot recovery, and adb reboot download
Wait that's right there's commands for download mode that you can put into the terminal emulator right?
Sent from my SPH-D700 using xda premium
i dont know how that would work, because they are adb commands, but he could try going into terminal emulator and simply typing reboot recovery or reboot download
Update Good thinking ac16313, just tested it. If he types su to get full system access reboot recovery definitely works( tested). Unfortunately download mode will not work though ( at least on cyanogenmod it just reboots). That would required adb reboot download via computer.
How could the Esn be bad if the phone was manufactured a month ago?

what happened
Have you found a solution, will it boot, and do the commands through terminal emulator or adb work?
I just got back from the sprint repair center where thankfully they told me there was an issue with there latest updates for the epic 4g with these symptoms. They downgraded the phone back to EC05 and now i have none of the symptoms anymore! Aside from feeling a bit sheepish for only trying to ODIN back to EL30 i'm very happy about the free fix! Fortunately it's my wife's phone so it's not too big a deal for it to remain downgraded. Hope this info helps somebody else!

Miui caused a major brick

Hi, I own a Galaxy S2 SGH T989 and I wanted to get the H1ve theme, so of course, I got miui. Right after I flashed it, I kept getting complaints about applications crashing, as well as the ics keyboard. Now, my phone won't even turn on. I've tried all ways I know to reboot (power button, volume and power, battery out and in, and all of that in the charger) and nothing works. Does anyone out there know how to turn on the phone. I just want to be able to factory reset on it. Also, when I try to enter download mode, the computer makes weird sounds at regular intervals while I hold down the phone keys.
ODIN flash back to stock. Make sure you have a battery while you're going into Download mode.
Are you doing the correct key combos for dl mode, vol down and power for 3 seconds then release the power button and keep holding vol down

S3 doesn't turn on when plugged in

Whenever I try to turn on s3 when it's charging and powered off it shows the Samsung logo then goes back to showing the charging logo and doesn't turn on. Anyone else experiencing this?
Sent from my SPH-L710 using Tapatalk 2
Its normal. Acts weird if u try to turn it on when plugged in the s2 was the same way. U have to let go of the power at just the right moment. Best way to get around it is to hold the button combo for download mode(vol down+home+pwr) when the warning comes up just hit vol down and it will boot as normal
You have to hold power until it vibrates.
I do hold it until it vibrates but it still loops back to the charging screen

I had the same issue last week. Couldn't get it to boot at all, I was able to go in download mode but it quickly powered back off. I ened up taking it into BestBuy as i just signed up for their insurance. They gave me a new phone out of box after trying themselves to get it to boot.

[Q] Stuck on boot screen, tried everything. Please help

Hi guys,
I updated to JB on my rooted S3 when it first came out a couple months ago. Everything was fine until a few days ago, when all of a sudden it turned off on its own. Since then the phone won't power on, it seems to always restart itself at the Samsung boot screen. I tried to do a factory reset, but the phone still restarts itself. Tried to put into download mode, no go either. Any idea on what I could do to fix it?
Thanks!
So I'm trying to mess with the phone again. I insert the battery and press the on button. The Samsung logo briefly flashes then the Samsung Galaxy SIII screen shows up. Then no response after that. The blue/purple Samsung logo used to show up and freeze, but now it doesn't even get to that point. As I try to power up again, there's no response until I take out/put in the battery again
If you are getting to a boot screen, it is only a soft brick. Do you know how to put your phone back onto stock rom?
To get into download mode
1. pull the battery, put it back.
2.hold power volume down and home key at the same time.
3.when your phone vibrates, let go of the power button.
4.when a screen comes up, let go of all buttons.

I tried that. But the phone just restarts itself as soon as the screen come up
Press the up botton to get into the download screen. You are holding the home and down too long. Release it right before you see the screen and press volume up to get to download mode.

If you still have a screen, it means you will be able to get to dl mode. Look it up to make sure you are doing it properly.

try this.
to get into download mode,
leave your phone on and connect to pc
press and hold both volume buttons
press and hold power button till OG's screen goes black black (don't let go volume buttons yet)
release power button (still hold volume buttons)
your OG should turn back on by itself in my experience.
and see if you can get into download mode.
This method took me to download mode when I soft bricked my OG.
Good luck!
P.s. same way for fast boot except it uses only volume down button.

what about download mode?
if you can get into download mode, flash ZVB stock via LGNPST.
