[Q] Help, possible soft brick? - Sprint LG Optimus G

I powered off my phone this morning and left it in a hot car for about 6 1/2 hours, and when I tried to turn it back on, no dice. The LG logo comes up for a split second and thats it. I can tell the screen is still on, it's just black. No luck booting into recovery. It is rooted, and I honestly don't know what recovery I installed, probably twrp. Any advice before I take it to best buy or sprint?

Are you sure it's turning off? Press and hold the power button for 20+sec. Then see if it'll boot, or recovery

Fixed using teeny bin/LGNPST after doing some research. I love the internet, I'm not smart enough to figure this stuff out on my own.

I had this happen to me too. I thought it was a software problem as well but its the power button. What I did was Odin back to stock and unrooted it. Went to T-Mobile since problem was still happening and they ordered me a new s2 and yeah

Try to beat it, its frustrating. You have to be quick. I was doing that fast. Once you go into cwm recovery use the bottom buttons of our phone to navigate thru it.

try this it will boot your phone into recovery automatically as long as your computer recognizes your phone. just open up the application bat file on computer within 2-3 secs it boots you straight to recovery. good luck.
Dude it sounds like your power button could be stuck the way your making it sound

i think this must be it... cus i managed to get it to boot, and everything loaded fine. but as soon as it got past the boot animation, the toggle that has power off, screenshot, etc (the thing that pops up when you hold the power button on) comes up immediatly.
how can i fix this bs?
Either you have a defective button or you need to clean it because it might be getting stuck for some apparent reason .
ok so i for sure have a stuck power button... im gonna go to t-Mobile tomorrow to try to get this sorted out.
thing is, im on the latest AOKP nightly, are they gonna **** me over on my insurance policy (the like 3-4 bucks you pay a month to tmobile) cus I rooted my phone?

Mostly likely yes if the tmobile knows its not stock. They could say it was your fault by saying you put a defective rom on your phone that's not factory. They try to get out of s**t all the time. But you could get lucky. But if I were you I would restore it to factory before I took it to the store. Just to be on the safe side.

[Q] Stuck on Samsung Galaxy S3 Screen

Any thoughts here, so far have come up with nothing. I was running odin trying to update and got interupted partially through the process. I'm able to boot the phone on, however it quickly flashes the Samsung screen then proceeds to the "Samsung Galaxy S3" screen where it hangs. I can't boot into recovery, I can't boot into download mode. All I can do is power the phone on and get stuck on this screen. It hangs there until I pull the battery. I've tried every combination possible to boot into recovery & download mode to no avail. If I plug the phone into my computer I can't get it to be recognized since its stuck on this screen. I don't think it's bricked since i'm able to power on, just stuck.
Any thoughts?
If you can still turn it on you can definitely get to download mode. Make sure you're doing the combo right..

Thanks for the quick reply, I like your confidence although I'm still skeptical. I do think I've tried all of the combos to get into download mode but I'm still not getting past the Samsung GS3 screen. Can you tell me which is the "right" combo?
Thanks

I've seen a borked recovery but never seen a borked download mode unless the phone was bricked which isn't the case here since it still powers on. The combo is vol-down+home+power then volume up at the warning screen

That combo is not working. No matter how long/short I hold it or how long/short I wait after the battery pull it still goes straight to the GS3 Logo and hangs forever. I think its bricked. Maybe I need to try a usb jig...

Well I'm sure it's not bricked but this is the first time I've heard a jig mentioned and I don't wanna pull my hair out cuz of a stupid comment. A jig would definitely do the trick here. I assume you don't have one so a word of advice : use Ebay. And buy from someone in the states. Its more than worth the few extra bucks.
I agree that your phone is more than likely not bricked like you may think. You need to hold down the 3 key combo until the screen actually powers on and then let them go. It takes a good 5-7 seconds after the phone vibrates before the screen powers on and then let them go. It should go into download mode and if you still can't get it then sometimes having someone else try it is all it takes.... but most definetly your phone is not hard bricked if it powers on.

Thanks everyone for the suggestions. At this point I'm going to have to send it in to mobiltech to have them hopefully revive it using their JTAG services.
I had this problem today.....
After much gnashing of teeth and swearing and being unable to use the generic android recovery due to removing my power button (don't ask) I flashed CWM with odin then used Android Toolkit to restart into recovery, wiped the cache, rebooted and Bob's your Mother's brother everything is rosy in the garden again................:laugh:

[q] at&t s3 dead

I was rooted with CM10.1.0 and was casually using the phone until it randomly turned off. I turned it back on and the only thing that happened was the "Galaxy SIII" screen flashed and turned off again. I popped out the battery multiple times to be welcomed with the same problem again. I can't boot into Download or Recovery at all. Anyone know how to fix this? (btw im on AT&T SGH-i747)
Try another battery.

Please don't provide false or miss leading information.
To OP. Fully charge your battery or use another one if its corrupt.
Try booting up into both recovery or download mode using the proper combination.
Use this guide to get your phone fully working again.

In some instance (very rare) your phones hardware can malfunction, but seeing how it still boots up I doubt its that's.
Follow my guide and you should be fine.

What about with it plugged into the charger and try to get to download mode. I thought I bricked my s2, took the battery out but it stayed on. Thought it was possesd bit it was plugged in to USB.
Can't hurt to try.
Definitely recommend download mode with cable plugged in to computer. Are you sure recovery doesn't work while plugged in to power?

Yep. It just loops on the splash screen. I'll try charging it to full and repeating your solutions. (It died off at 80%, very strange). Thanks for your replies though!
Ok guys, seems that my issue isnt the phone being bricked. I left the battery out all night and popped it in the next morning. CM loaded just fine. However after about 10 seconds of it loading, the power menu flashed, i clicked cancel, and then it immediately shut down again, and the usual problem continued. Any thoughts? (btw the phone died at 80% battery the first shut down it had, right now it should have been nearly 100% after charging) Also, connecting it via USB doesn't help at all. Sometimes the blue recovery words flash when i try to boot into recovery, but nothing happens after that.

It could be a bad battery. Might also be the battery contact points. Worse case is something is wrong with power channels on the Mobo. If it is the last then you will have to warranty the phone if you're still covered. I would borrow a battery first to rule out whether or not it is the battery itself.

The power button seems to operate normally, but that could also be one of the things that are causing problems. Once i find someone nearby with an S3 battery i'll see if it's actually a battery problem (most likely the case).
I'd thought i'd mention this as well, whenever i pop in the battery, the phone vibrates and tries to turn on, but doesnt actually do it. Anyone have any ideas what could be causing this? power button maybe, but battery?
If the battery out all night boots past the splash screen maybe you could, if you haven't, leaving it out and first thing try download mode. I've been in bad spots but this pretty crappy. Probably to technical for me but Good luck. Let us know how you do if none of the posts help.
Found the problem. The power button is always acting as if it's being pushed down when it actually isnt. The phone starts up perfectly when i hold the phone horizontally with the power button facing down. then when i put it back into portrait mode, the power menu flashes, and its turns off. any knowledge on how to fix this then?

Um I'd say taking apart the phone or mailing back for warranty even try taking it to an att store.. Its hardware and not software so they should replace it

Well by formatting system you removed the android os from the device, of course it can't boot anything after this. Put the device into bootloader and flash a rom or factory image. This should bring it back into working condition, that is if you haven't erased the bootloader too.

If you are lucky, you may just be out of battery. Just plug it in and let it charge. Once it's charged, press vol down + power both at the same time and hold both until the bootloader comes up. If you get to the bootloader, then you can just put the factory image back on there.
If you are unlucky and you somehow blew away the bootloader, then you are SOL. You will know the bootloader is gone if holding the vol down + power does not boot you into the bootloader (assuming you have charged the device and are sure it is not out of battery).

Did you hold the vol down + power button for a minute or more (now that you've charged and are sure battery is not out of juice)? Sometimes takes awhile for it to boot.
If the device doesn't have a bootloader, there's not much you can do that I am aware of. On most devices, you'd have to JTAG to get anything back on the device if the bootloader gets wiped.

[Q] Bricked

So I guess I bricked my phone when I tried taking it back to stock... The phone will not turn on, will not respond to any charger, WILL NOT DO ANYTHING............................
Honestly I have taken mine to the point a few times. First time I drained the battery to the point it was there. See if u can get to dl mode plugged in with no battery.
Second time something weird happed at a strange point in the flahs...and I really thought I toasted it.I reluctantly did as it said in the "so u bricked ur epic" thread and un plugged it, removed sd card, removed battery and let it sit for an hour. I am not playing when I said it worked for some reason. If I read it I would not have believed it but that is the way it went. Give it a whirl....noot like u can mess it up more. There is a guy who will recover it if it is really toast...via jtag

This just happened to me, after a bad odin back-to-stock trying to fix some problems the phone just turn off, no screen, no leds. The phone is dead, can´t access to download mode either. I change the usb cable but didn't show any sign of life. After about 30 min of giving up, I tried pressing the Turn On/Off + 1 buttons, trying to access Download mode several time just hoping it magically works, and suddenly there it is, Download mode. After that, phone is working.
Not sure is this would help, but it least I tell me experience. Good Luck.

That is what I have seen to. As suggested above... rip the card and battery and let it sit for a while (hr plus I would say) and try again with no battery to get to dl mode.
