Galaxy S3 Won't Power On

Hi , I'm having problems with my Galaxy T999. I have rooted and have not yet installed any kernels/roms. The only thing i did was installed a couple apps from the play store . and wanted to check out the CWM recovery menu and was going to try to installed "hyperX camera mod". First thing i did was shut off the phone . Then pressed on the Volume up+Home+Power button . After doing that my phone didn't turn on or anything , no vibration or anything . I hooked it on with my computer and press the power button and it was able to connect and then disconnected. I am at lost now and can't seem to find any answer . Have looked every where not sure what to do now. Any solution will be much appreciated .
***
It seems to disconnect due to no driver found for QHUSUB_DLOAD .
Without any solutions I'll probably gonna get my phone replace . T_T

Does your phone disconnect immediately, or does it stay connected for a brief amount of time? If it stays connected briefly, try using adb during this period to boot into recovery. The command is "adb reboot recovery" (without the quotes).

Try to remove your battery then plug in charger. See if you can turn on. If you can turn it on, leave it 30 minutes. Then put in the battery.

By the looks of the result the computer gives you when you plug it in, seems it is hard bricked! Are you sure you didn't flash anything from the I9300 section like a rom?

The hyper x camera mod isnt entirely for our phone. I've read that it's flashable to our phone though, so I'm not sure what's going on here. Maybe the OP needs to link where he got the mod. Ih and stay away from the intl version all together.

Yup its a paperweight. The Intl version has the system partition in a different place. So you borked an important one.

Only thing that's throwing me off is that the OP suggests he didn't actually get around to flashing the mod.

That's a good sign! Looks like you're able to enter Download mode. Download Odin and flash a stock ROM.

No that's a sign of hard bricked. Check other threads asking for help. They all have that displaying after they connect it to a pc

Oops, never mind! chrisram88 is correct. :good:

I pretty much got the same problem except with an i9300. Is there any way to fix a hard brick or does it need a new motherboard??

SGS3 T999v wont start up.
My sgs3 t999v would turn off by itself every other time I hit the lock button.
like I would be txting and then if I hit the lock button it would turn off.
So I though a factory reset would fix the problem. (volume up + home).
after the reset it still kept turning off randomly.
and now I cant even get it to the normal interface. or get in to the manual reset mode.
Device was previously jail broken, however was returned back to stock and was working fine for 3 months.
I had my otterbox on for every fall my phone had, so I dont think it would be a hardware issue.
the phone was running 4.1.1 I believe.
stock rom.
help please! :C

Can you get download mode? (Volume down, HOME and power)
Even though you have a case on it, it sounds like it was probably damaged by one of the falls. Most cases as far as I'm aware mostly protect the display. The shock from impact can still damage internal components, even with a case built with this in mind.

Hey thanks for replying!
I drained the battery and got a new charge in it and managed to get it booted up
however now the problem of the lock button is still here.
like if i use it to lock my screen it just turns off on me, and it takes multiple times for me to get the phone up and running again.

you could see if you could find a widget or widgets that will basically put a button on your screen that can power off, enable lock screen, reboot recovery/download, etc.
Then just use the HOME button to turn the screen back on.
It sounds to me like a hardware problem, but if you can flash another Rom and do a full wipe/factory reset you'll know for sure.
I hope this helps. Not sure what else you can do besides getting it repaired or replaced unfortunately.
Maybe someone else will have a better idea though.

I don't know what happened... turned off, not turning on again

i don't know what happened, i didn't root it or did anything to it. it just randomly turned itself off and didn't start up again. then suddenly it happened to load the battery again and i was able to boot it, but here the ****ed up part came... it showed me the samsung startup logo and everything but then weird green vertical stripes(like the matrix) appeared and nothing more happened. few reboots after, same problem as in the beginning, it's not starting up again. help me please

[HELP] Power off loop issue :(

So, lets cut to the chase here.
Was playing around with my CM10.1 powered Galaxy W when it shutsdown by itself when its on sleep mode.
I tried switching it back on and it just shows the "Samsung" brand name in verry short seconds and then repeats from the start. How to fix this manually? Am i suppose to go for SSC???

If you didn't install any custom kernel/mod/system tweak, then from CWM recovery, you could try the "wipe data/ factory reset" option. See if it helps in any way. Although...from what you're saying...looks like you've got some custom stuff in there. For this case, I'm afraid your only way out is by making a pristine install of that ROM.

I only flashed MonsterV15 ROM after i pristined everrything. Also, I can't go to CWM properly as my phone keeps rebooting. The boot sequence i guess is Samsung -> Model no. -> bootanime' but i can only go for the first step and then it reboots. Another thing i discovered is that my phone switches on by itself when i insert the battery

Well, both sound like ROM issues to me now. But apparently at least one of them (the reboot issue) should be fixed. So head over to the dev thread. Looks like there is some new stuff in there. Also if the auto-turn-on thing when inserting the battery is not fixed too, you might as well report this in that thread.

Uhm, actually, the auto-turn-on issue & reboot issue thing happens when i insert the battery as well. Also, i can assure you that this ain't ROM issue. Previously, when i used OneOfAKind ROM, i switched SIM cards and then the auto-turn-on issue & reboot issue happened from there. I left my phone and battery apart for a day and then tried putting it backand BOOM it came back to life. So from there, hoping tht THANG won't happen again in my whole life, i pristined installed MonsterV15 and all went well when the THANG happened once more and i ended up heree .___.

Standard battery? Could you try with another (maybe stock) battery. Also...does it happen with any CM version?

This ain't software related....it's hardware related.....guaranteed.
It's a faulty power button.
The power button is behaving as if it were being continuously held in.
If you continually hold the power button on a normally booting W I bet you could replicate these exact symptoms. The results would be the same on insertion of the battery too.....
I answered an identical question a few weeks ago in this forum....and having done some research on the issue, I can tell you the only way you're going to fix it is take it to a service centre where they'll replace the entire main board......the power button is soldered directly to it.....
I'm guessing you can't successfully enter download mode either? So flashing back to stock beforehand isn't an option either....that shouldn't be a problem though.....if you can't get the phone to boot, they won't be able to either.....so they won't be able to tell what OS you're running. Even if they can, there's NO WAY they can argue that running a cusROM caused the power button to fail. Don't forget that the warrantee on Samsung phones is 2 years........

yea... I totally agree with keithross39. it's hardware related... Me and @hurtsky have this problem before too~ what i did is, insert the battery (and it will power on automatically). then spam the power button while it's booting... and it successfully booted (because the power button is not 'holding' anymore), you will see the reboot dialog pop out or screen turning on and off automatically. If you are lucky (like me) i fixed it myself by spamming the power button add don't press the power button anymore.... For now, I use the notificationbar's widget as screenoff, use terminal emulator to reboot or reboot recovery. I know that's weird, But I don't want to send it samsung because my phone is not original, it's AP

Desire HD keeps restarting

Hi guys, i have a big problem on my htc desire hd. Its rooted, S off etc. Cca. two weeks ago htc starts restarting. I thought its a battery problem, couse i tested it 1 months ago and it has only 200mah. So i bought new battery, but its the same. When i charging the device, it does not restart never. When stop charging... restarts. When i using the device (browsing web, texting, etc) its fine, it doesnt restart. When stop using... restarts. These restarts keeps repeating every couple of seconds. Then i hard reset my phone, doesnt work. Then flash with CM 10.1, manually install kernel, but is the same. I dont know what more can i do. Does anyone have any idea? Thanks and sorry for bad english

News When phone goes to sleep mode (black screen), it shuts down. I cannot wake it up, if i press power button, it just booting again.
In recovery it does not restart.

just installing another custom rom (try SVHD v2.1.0) from recovery..don't forget to full wipe/factory reset except the sd card..before installing any custom rom..
hope this help..

I already installed 3 new roms, but there is no difference. Now just shuts down when idle. If i use the device, is ok. If i press power button (sleep), i cannot wake it up anymore. ALWAYS:crying:

Is this behavior also happen on the stock rom or arhd rom? Try flashing them and see whther the same problem occurs

Do you use a protective case?
Sounds like a physical thing on the power button...

No I mean if it reboots as well after 10-25 minutes in recovery or download mode like it does when booted normally. That would confirm that its likely a power button issue

Are you using GT-I9500? If so this is the wrong forum.. But what I would do is backup all my personal files, important messages etc. flash stock firmware with Odin, reboot to recovery and factory reset.
