[Q] Unable to boot the phone - Galaxy S III Q&A, Help & Troubleshooting

Hello all,
My GS3 is not able to boot up. No matter if I press only the power button or press DOWN+HOME+POWER, the screen just keep black. Nothing responses.
I have found many threads about bricked or SDS etc, there's no any help.
Do you guys have any suggestions? Becacuse I am abroad recently and not easy to send it to the service center in UK.

nothing else to do

Try another battery, leaving it plugged into the charger for an hour.
Does the red light or charging screen appear when you attach to the charger?
If download mode doesn't work and the above also fails then it's dead and only service can help you.

Thanks for your info.
I tried all above methods, but all failed. I hope that the phone is still in warranty. I bid it on eBay a year ago and have no idea about how long the previous owner had used it.

[Q] Phone will not turn on NEED HELP PLEASE

Hi I just recently bought an HTC HD2 and I got it used. I checked out the phone pretty well and it worked fine when I purchased it. I got home and the battery was dying and eventually died before I got a chance to charge it. So I left it on the charger, the LED light came on and was flashing as if it was charging so I went out for a bit. Once I came back I noticed the LED wasn't on anymore so I tried to start up the phone and the phone wouldn't turn on. I took out the battery and put it back in still nothing. I've even tried using a different battery and still have the same results. I talked to T-mobile and they said to try going into boot mode by powering up holding both volume keys and the power button and I cant get it to start up at all. Anyone have any ideas as to what could be wrong?

When battery is charging the LED does not flash. Normally it just lights in orange. Are you sure that the second battery you used was well charged? Take a tester and measure the voltage on the battery pads - it must show some 3.8 volts. You may check also if your battery is charging on some other phone to confirm that it is healthy before to decide that phone is dead.

just shows what tmo customer support know, , , thats a hard reset they've described, not entering bootloader.
Ok so on my lunch break I went to the t-mobile store and told them my problem, for some reason they were able to get my phone to somewhat charge and start up. So its for sure the battery. I have no idea why the secondary battery I used had no effect on the phone. After work I'm going to go find a new battery and hopefully this will solve the problem. I'll keep you guys posted.
winner!

Galaxy SII BLACK SCREEN - DOESN' T TURN ON

HI First time here for me.
I was surfing the net on my t989 and the screen went black. I try to restart but the phone vibrates for one second and nothing happens. I took out the battery and SIM card and put back the battery, push ON button, phone vibrates but do not start. I try to charge but it vibrates every 5 seconds, but it doesn't start. The phone is new - one month - just install 9-10 aplications. Please help. Thanks
Same thing happened to my SGS..power IC was damaged in mine.

Have you underclocked/undervolted it at any stage? If so, try using ODIN to restore to stock, if you can even get into Download Mode. If not, send it into a Samsung Service Center.
Yes it sounds like it is not charging and the battery is flat! With the phone OFF you should briefly see a picture of the battery when you plug the phone into the charger.
Try putting in a fully charged battery from an another S2.
Can you get to Download mode (Powered off, press Vol up+Home+Power at the same time) or Recovery mode (Powered off, press Vol up+Home+Power)? If not, then you're in really bad waters...
Hi,
Thank you for your answer. I did't do anything to this phone since I bought it. Just 9 apps dowloaded. Worked fine and yesterday it got dead. I just do light web surf and some emails. Do you have any idea, please? I hate to have to returned since I'm in Canada and I couldn't even register this phone with samsund.com sice it is allowed only US addresses.

If you can't even get into Download Mode, as detailed above, really you're out of options for the most part. Looks like returning it is your only option.

Can only get to a Sony logo flicker when plugged in, dead when not

Hey guys,
Went to use my phone yesterday, never flashed or anything like that, and it just wouldn't respond. When I plug it in the sony logo flickers every 7 seconds and it won't respond to any button combination for rebooting. When it's not plugged in I can't get any sort of response.
Please tell me someone has encountered this before.
Same problem
Hi I have the same problem. Only is that the screen flickers every 0.5 seconds with SE logo.
I downloaded the repair tool but not abLe to process the repair on my phone. Nothing works. Opened the phone, removed the battery plug, tried to power on the phone without the battery plugged-in, nothing. Please help.
Sony repair wont help me. Apparently there is calcium on the magnetic ports or liquid damage in the phone; no liquid damage at all, phone was never put in water and nor any of the white stickers turned red.

Maybe due to corrupt software. Try flashing a new firmware using flashtool.
Hey guys, got some update from a repair center I usually deal with. It seems that the motherboard is dead. According to them, it seems that the battery might have been overheating and might have affect the motherboard. I'm going to try to call the sony mobile tech support and see if a repair mailer could be sent to me and going to keep you posted.
Cheers,
Gabriel

G Alpha wont turn on.

I charged my phone night before last and I used it in the morning. I left it on top of the bed when I had to do stuff.
I went to get my phone and my wife said it was warm and that she found it under the blanket. The blue notification light was flashing but I could not get the screen to come on via the power buttom.
I cannot get the phone to respond using any methods.
Could my phone have just died in an instant?

I already reseated the battery.
I cannot get to recovery mode with volume up + power + home.
I dont understand what could have happened.
Blue notification light was flashing. I hit the power button to turn the screen on but the phone did not respond.
I pulled the battery and I put the battery back in but the phone would not power on.
No indication when it is charging.
Kies wont recognize it.
Wont power on, at all.
Stock rom with only a few extra apps. I deleted most of my apps when my phone would randomly lock up.
Could be bad battery. Try getting to recovery as soon as you plug in charger.

I tried to boot the phone with 3 different chargers with the battery in and battery out.
My charger
My wifes S6 charger
My moms Kindle fire charger.
I tried a total of 6 times to boot the phone, nothing.
Could the motherboard be bad?
Could it be hard bricked?
Could be the battery
Could the phone turn on without the battery while being plugged into charge?
I guess no, try battery from another alpha/new one.

S6 - Bricked - Black screen and Solid White LED

Hello, friends
Out of the blue, my S6 Edge tried to restart, but got stuck in a loop at the Samsung Logo. One or two times it went to "insert pin" and then restarted again. I tried to Force Restart and it didn't solve the problem.
After a few tries, I managed to wipe the cache partition. Now it's simply bricked with a black screen and a Solid White LED. I can't restart it, enter download mode or safe mode or anything. Odin doesn't recognize it at all. Is there anything I could try?
The phone is not rooted.

Thank you! Tried it. Doesn't work. It's beyond my understading why would it behave this way after I managed to clear the cache. At least before that it went into download mode or safe mode. I still suspect a software issue.

So vol down + home + power will not get you to download mode?
How about recovery? Vol up + home + power?
This happened to me before and the way i got out of it was hold only vol down + power as soon as the screen went off completely (no led lit) switch to download mode combo.
Tried both of the commands. They didn't work. I will let it drain the battery completely and then see what happens.

reminds me of the bad emmc memory like the note 4s had.
some times completly letting the battery drain can fix it being "stuck". then recharge for 20 min or so then trying to turn on.
if u plug it into pc does it reconize anything in device manager
even unknown device or descriptor failed anythiing at all?
This morning the LED was off, so I tried to recharge it. Nothing happens. Also, the PC doesn't detect it at all. I think it's safe to assume I need a new phone. Too bad...at least if I was able to recover the data on this.

you can thank sammy for no ext sd card for that one or more than likely pics would be on sd
now one last sollution is to try buying a cheap battery my note 5 had a issue it shut of one day and wouldnt do nothing i understand ures was blinkik and trying at least
so its a leap but last resort
same problem here started over a week ago - samsung S6: black screen, constant white led. tried all variations of resetting with buttons. over a year ago i replaced the battery, and its been fine since. when this no boot issued happened i also tried changing the battery to a known good one. on inserting a battery and then pressing the power button the indicator led will go to green for less than a second before changing to constant white, and it stays that way no matter what until the battery is drained or the battery is removed. Strange thing is there is no information from samsung on what this behaviour means, but I've come across dozens of other S6 owners on the web with the same problem, so this is obviously diagnostic behaviour designed by samsung - but no info from samsung. the phone has never been damaged or watered or rooted so I'm at a loss.
Confirmed diagnostics:
The phone will respond to the power button and attempt to turn on
The phone will charge a battery, so the charging circuits and battery circuits are working.
The phone does not get picked up by a Windows 10 PC with Kies installed in any state - other samsung phones get picked up no problem.
Same here
I have the same symptoms. When I hild the vol up+home+pwr I get a green let for 1/2 sec then white. No other combinations do a thing. I swapped the battery for a new one. No luck.
Mine started a few days ago. The phone was 50% charge and i plugged it in for two hours. Came back and it had a solid red led. After a few hours the red light went off. It was then 100% unresponsive. I then took it apart and disconnected the battery. When I reconnected it, it started to do the white let thing described above

I have one that behaves exactly the same I changed the battery and didn't make any difference. my next step is to replace power management chip. I'll let you know.
Any luck on this?
Mine has been like this for a couple months, kind of gave up on it, but decided to give it a go again!
Same problem here, just happend after switching the battery. Anyone have solved this?
I found a kinda solution, plug your charger in and charge past 30% then unplug charger. then use just vol down and power button for 7-10 seconds, after 7-10 seconds just release the power button while still holding vol down button until you see samsung logo, you can tell if you did it wrong by the solid led being back on, repeat until success, once you have it on do NOT press the power button or it will RESET back to solid led/black screen.
I have the same problem with my s6 active and similar story to dbeeheim. Has anyone fixed this? And can anyone confirm that enzo13's solution works?
Much thanks in advance!!
i have same problem!
Suddenly my S6 dead, battery was ~80%, no charge
yesterday i try to change battery, after that if push power button, LED small light comes but in white with purple, then stuck. (it's small Notifications LED)
and i chnge the screen, but no more than white/prople LED.
(no any thing on screen, always black..)
what is the problem?
i think it's battery because it last month didn't work good, and it's old 3years battery.. but no idea..
Hello guys my Samsung S6 sm-g920f has the solid white led and black screen. Really no fixes?
thank you
Same issue
I have the exact same issue. My Galaxy S6 Edge (G925F) suddenly died and won't get past the 'Galaxy S6 Edge Powered by Android' screen.
I am unable to reach the recovery options. I've tried flashing two different stock ROMs with Odin which succeed but without successfully turning on my phone. I've also tried flashing TWRP with success in Odin but it won't get past the 'Powered by Android' screen before turning off after +-4 seconds. The white LED is on even when the screen is black.
Just had this same issue, my battery died and I forgot to charge my phone overnight, woke up and it would not turn on, black screen. I did manage to replace the battery and do several diagnostic tests on it. My battery was receiving about half the power output it should be (this is normal it's a 4.5yo phone) and when I replaced the battery with a new one, it did not turn on. With wireless charging I can tell I am receiving a charge and with standard I can not. The screen does not indicate it is charging with either method but my wireless charging pad lights up indicating my phone is being charged. I think it may be the processor or screen itself. This really sucks because I lost all my data on my phone and data recovery can be over $500
