i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

Hey guys wondering if anyone experienced the phone being basically bricked without actually unlocking, rooting or anything.
It has happened before one, just laying on the table and the phone turning off but it came back on after a while.
Today it occurred again but has not turned back on for two days. When charging the only light is the LED flashing constantly every second. If I hold the power button and volume up then the flashing of the LED changes pace to One long flash (1 sec) to two quicker flashing ones (.5 seconds). If I unplug it and plug the phone back, The LED flashing is back to the original constant pace.
When unplugged sometimes holding the power and volume up button initiates the LG logo and then turns off and then shows the logo once more and then turns off for good.
If I plug this into the computer, its like someone ejecting a usb and plugging it in like a maniac. I heard the connecting and disconnecting sounds from windows nonstop like as if its about to blow up.
I've tried holding the power button for a minute the same goes with different combinations with the volume buttons.
The only thing I haven't tried is opening the phone, kind of afraid I will mess it up. Any solutions?

Never heard of this but I can throw a few suggestions out. Try unplugging, then holding both Volume buttons and the power button (All three) for about 10 seconds. Try different USB ports.
Try this if all else fails: Source: http://cellphoneforums.net/lg/t348484-perform-master-hard-reset-lg-optimus-g.html#axzz2YPtvkfDk
To Perform a Master Reset via Hardware
1. Turn off your device.
2. With the device turned off, press and hold the Volume Down key as well as the Home key at the same time.
3. While both the Volume Down key and the Home key are held down, press the Power button.
4. When the LG logo appears, release all the keys.
5. Scroll to and highlight wipe data/factory reset by pressing the Volume Down key. Then press the Power button.
6. Scroll to and highlight Yes – delete all user data by pressing the Volume Down key. Then press the Power button.
7. As soon as the wipe has been completed, press the Volume Down key to scroll to and select wipe cache partition. Press the Power button when ready.
8. As soon as the wipe has been completed, press the Power button to select reboot system now.
9. The master reset should now be successfully completed and your LG Optimus G should restart.
Tried three buttons, nothing yet..As for the hard reset the home button is touch screen so not sure if it would would for this device

I have no idea, when I plugged it in and check device manager, its constantly refreshing as its connecting and disconnecting the phone very fast. Is there another way to check

Anyways, doesnt matter guys thanks for trying, decided to just go in att and buy a samsung s4
Hello,
I'm posting this for a friend, because his phone is "dead" and he is unable to post himself.
Earlier this year he brought a Galaxy SII from a second-hand phone shop, and it's worked fine up until now. He updated the ROM to the official 4.1.2 and since then it's had issues connecting to his home WiFi (unrelated, but it lead me to suspect the ROM) but it connects everywhere else. Then yesterday his phone just went blank and turned on again - the boot sound played at the touch buttons lit up for a moment and then faded as with a normal boot. But the screen was blank apart from several white spots, and a load of coloured pixels. I saw it myself today, and the colour of the pixels is random, although usually red or green, and the phone gets incredibly hot about a minute after turning on.
Is this a ROM fault, or could there be something more serious to it?
Just a shot in the dark, as I've never owned a Samsung, but could it be the "sudden death" bug that they allegedly have?
Thanks
Does it go to recovery? Factory reset. If not does it go to download mode?

I'm not sure - I think I managed to get it into the bootloader, but there's no way to tell because there is nothing on the screen but the white dots and random pixels. All I did notice was that when I removed the battery and turned it on again even more pixels appeared. We only went by the sound and touch lights, so it appeared to boot, but we don't even know if it switched straight off again

you are not sure ? did you try to go into recovery or download mode ? shutdown the phone first
Recovery = Volume up button + Home button + Power button
Download mode = Volume down button + Home button + Power button
Press vol+and home button and power button till it boots to recovery. Keep them all pressed down till it boots. If not try vol- home and power till it boots to download mode. Has he dropped it?

We tried that, and the touch lights came on but with no boot sound. The screen didn't change, just white dots and pixels, but it was working fine the day before.

Tried both, the screen just did the same thing and the phone got very hot very fast, and he said he hasn't dropped it at all, but that someone in his family may have, he's not totally sure because nobody admitted to using his phone.
Screen is prob broken. Pixels on it..not good. No recovery or download mode..really bad. For it too get really hot really fast may be a mb problem. Send it to service centre

Okay, thank you! He tried calling them and getting a quote, but the guy on the other end didn't seem to know what to do, and the man who owned the shop he brought it from offered to repair it, but for almost double what it cost him to buy the phone.
Thank you!
No problem mate. Get a second hand one. Prob be cheaper to do that now the s4 is out. Mb cost alot.

please remove the battery for like 10 minutes, wait a little bit, then try to go into recovery or download mode,
if that doesn't work, try this:
1.Press the key combination for recovery
2.Samsung logo appears - hold the buttons pressed.
3.Prompt disappears shortly - you still hold the buttons.
4.Samsung logo appears again - hold the buttons still pressed.
5.Count to 3 & let go, dont press the buttons anymore.
After 1 - 2 sec farther the Samsung logo disappears and the recovery starts maybe, i did that on my old i9100

Thank you, but that hasn't had any effect. Still a blank screen with white dots and thousands of coloured pixels. Thank you for all of your help though!
Hello guys, I'll try to be as brieff as possible:
My cousin has a SGS3, which suddenly started showing the power options screen (when you long press power button). Now his phone restarts on its own every time. When you insert the battery, it turns on by itself. If you try to access download mode or recovery mode, it does it but restarts again. I read it may be the power button is not working properly, but I dissassembled the phone and the switch is works normally (it's not broken, either stuck). I read several solutions about clearing cache and stuff, but it just keeps restarting! Like if someone were pushing the powerbutton every time. Btw, he discovered he can turn the phone on and actually stop the phone from restarting if he continously presses the power button and menu button alternatively without stopping (which is useless). When he stops doing that, 3 secs later, it restarts again. Any suggestions?
It's a hardware fault, did you test the button with a meter?
If yes then something else is shorted, to power on when the battery is inserted.

Ah, so this is merely hardware. I did not test it, but now it seems clear something is wrong on the inside (which, unfortunately, I cannot help with). Thanks mate!
So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?
try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.
Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation
So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.
glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.
Hey everyone,
Hope there are still people around in the F1 forum.
My F1 was sitting in the drawer for almost 2 years now.
I'm trying to boot it now, but it gets stuck in the process. It basically keeps going like this to infinity, i gave it hours and it's doing exactly the same thing.
As you can hopefully see in the video, when i try going to fastboot (by pressing power+volume down buttons) it shows the fastboot logo but gets stuck there.
From that point the only thing i can do is try to reboot normally again, which brings me back to the first state.
Connecting to the computer doesn't do anything.
Any ideas?
Ideally i'd like to keep the data but i'd consider anything at this point.
Many thanks!
Try to restore. Press volume up and power button when logo appear release power button but keep holding volume up until recovery has shown up

Thanks for the tip!
Actually, emptying the battery completely and then charging all the way to 100% (without trying to reboot before it reaches 100%) eventually did the trick and the phone turned on with all the data.
