I have an Optimus G E970. When I turn it on I have to hold the power button for a couple seconds. It never shows any ATT or LG or google logos on startup. It goes straight to a black lock screen. I have tried for months to get into download mode. recovery mode, emergency mode and fastboot to no avail. If the battery dies it has to charge for a few hours before it will come back on. Even then I have to unplug the charger from the phone, then when I hear the ATT tone I have to plug it back in. Somebody please help.....I just broke the ribbon on my camera pulling the battery out. Which did nothing. If I can get it into download mode I am confident I can flash it back to stock and start over. It is rooted and has freegee installed. The phone when on works fine with no issues. I want to update it though. hhhheelllppp

Hey guys, I'm desperate for help. I am running Slimbean 4.3 on my Vibrant, and last night while I was just browsing Reddit in an app, my phone shuts off immediately with no warning, no shut down sequence, and plenty of battery charge left. Now it just sticks on the Vibrant boot screen, restarting every 20 seconds or so if I try to turn it on, or if I plug it in it just stays at the spinning circle. I am unable to enter recovery mode through all the button combinations I have tried. The best result I have had is taking the battery out, holding up/down volume, then inserting the battery. This gets me to the "downloading, do not turn of target!!!" screen, but I cant get past that screen. The only computer I have access to is a mac, so I have't been able to try anything using ODIN. Does anyone have any tips or advice, I really can't afford to buy another phone right now with Christmas coming up. Thanks a lot guys.

Usually it send the phone to download mode when you have a USB or charger cable plugged in. Make sure you have that port clear then try it. Mac's can run Hemidall (I think that's how you spell it) which is like an odin equivalent. I don't have much experience with that but someone else here might. Try researching that as well. That should put you on the right track
A few days ago I looked at my phone and the 'Device Options' menu kept appearing over and over as if someone was holding the power button down. I managed to turn off the phone and since then I haven't been able to get it to reboot. The phone will boot to either the 'SAMSUNG' or 'Samsung Galaxy SIII' logo screens and then the screen goes blank. I can occasionally get the phone to start booting into recovery mode but it turns off before getting to the menu, same thing with download mode. This seems to be getting worse as well, as the first few times I tried to get to recovery mode I could at least get to the menu before it turned off.
The phone will not charge either. I can get the charging indicator (red LED) to come on if I remove battery, plug in USB cable then reinsert battery. However, the battery does not actually get a charge when I do this.
I have tried swapping in fresh batteries, removing SD card, removing SIM card with no effect. I tried taking the phone apart and I can't see any problems with the power switch.
Any ideas on what is going on? I am two months out of warranty. I have ordered a USB jig since I thought it was bricked from a firmware/software issue but now I am wondering if it is actually a power button problem.
The phone is a Rogers Galaxy SIII, not rooted, running stock firmware.
Thanks.
My buddies rooted i717 with CM10 4.2 has been running great. Then it started to turn just turn off on it's own. Last time it turned off now it won't turn on.
When you hit the power samsung logo flashes normally then screen goes blank. At this point it keeps making that powering on vibrating sensation repeatedly. Touch power button and this routine repeats.
It will not boot into recovery. After the sammy logo flash continuing to hold down power +/- does not yield recovery mode. It just starts the vibrating loop.
I thought I will just install stock via kies or flash JB via odin. Well odin mode turns on ok but shuts off after barely 2 to 3 seconds. I have tried this with and without battery, plugged in and not plugged in on pc but end up the same way.
I have checked battery, same is super aok. I swapped batteries with my i717 and mine turns on just fine all the way. My buddy doesn't mind any which way the phone comes back to life.

If you read and run any kind of search, you would find similarities to the all common stuck power button.
Flick tye back of the phone a few times.
I know, you can feel it click.......doesnt matter, flick the phone.
If you are brave enough, you can open phone and clean with qtip and alcohol.
I am not.

I did actually, it didn't work. I thought there's was something that could help before I have to open it up cause of time. I change ports, cameras, etc on these models so it's not a biggie to clean it. Will do this this weekend.

There have been multiple times that I couldn't get into recovery mode, but download mode worked fine.... I just reinstalled CWM and reflashed.
May not help the root cause, but may get you past the no-recovery mode issue.

Neither works. DL mode turns off after 2-3 seconds; I have even induced it with a DL dongle. Repeats the same. Recovery mode is a no go-phone flashes sammy logo and goes silent. You are right the first issue to fix is the power button. I will update this weekend once I take it apart. Thanx all the same.
Today while getting lunch my GS4 shut off and wouldn't turn back on. I am running Hyperdrive RLS18.1, and it has been working fine up until today. I have tried everything to get it to boot past the samsung custom logo. The steps I take to get it to the logo are- 1) Take out the battery 2) Put battery back in 3) Screen boots up with samsung logo(if it is plugged into the charger it shows the charging battery then goes to black) 4)the screen turns off. I have tried putting it into download mode by holding the home-power button-volume button combo, but it won't boot into download mode. I tried plugging it into the computer and it doesnt recognize it because it is off. I have two different batteries that I tried to put in the back, but they both do the same thing. Does anyone have any suggestions on how to go about fixing this? And if I go into the verizon store and my phone gives the samsung logo with custom underneath it will they uphold the warranty? I doubt since rooting voids it....Thanks for any help in advance!
After trying some more options to fix the phone, I was able to get it into download mode, but then the screen turned off again. I realize that the problem is the screen won't stay on for more than a second or two. No matter what comes up, the screen turns off. But when plugged into the computer, it also just shuts down.

I actually had this phone before the bootloader was locked, I think. I never had to use it to root.
I have no idea why this worked, but after letting my phone sit all night, I tried this video -https://www.youtube.com/watch?annotation_id=annotation_1286109531&feature=iv&src_vid=SSLZFmhmBlc&v=uc0afHKahR4 . I have no idea why it worked, but it did. So if anyone comes upon this thread and has this problem, feel free to contact me and I will try to help you fix the problem.
Brand new phone, had it a week. I decided I wanted to root it, first step is to get it into download mode.
With the phone completely powered off, I hold the volume up key, and plug in the USB cord (which is connected to a Windows 7 machine).
Rather than being greeted with a download mode screen as I've seen on youtube / indicated here, I immediatly get the LG screen, and then a battery charge state screen.
I've tried volume up, volume down...no luck. Just goes straight to LG logo and then battery charge state.
Any ideas?
EDIT:
For those that get this issue, I resolved it.
From the battery screen, I held volume up and hit power. I saw another thread with this same issue, but they didn't post how they fixed it.
Thanks!
Thank you, good info to know just in case. Glad you solved it for yourself and it's good users who share their info here for others to find. Never know when/if an issue like that would pop up for us frequent flashers.
