Help phone wont turn on

Hello this is my first post by the way and i really need help please i just rooted my lg nitro hd and was flashing the CWM on it and when i turned it off to check if it worked it will not turn back on at all not to cwm or regular boot please someone help me i just got this phone 2 days ago.
thanks in advance

What do you see when you turn the phone on?

does the charging screen come up when it is plugged in?

it doesnt power on at all and the charging screen doesnt come up either

mine too,it doesnt power on at all and the charging screen doesnt come up either,
anyone help!

I don't know a way to fix this problem but I have seen unbricking threads for this phone that may help. I'm not sure though because I haven't tried them. I did however also brick my nitro two days after I got and I brought it back to at&t and acted like I had no clue what was going on. Mine was stuck in a boot loop and possibly fixable but I needed it for work and didn't have time as I was on my way to work.

Hey try pulling the battery then reinserting it with USB plugged in to see if you can breathe any life into it if you can get anything to show on the screen that would be the first step then after that there may be a chance of rescue also try to let it charge for a while and come back to it, I brought a phone back because nothing would show up on the screen but when I brought it back to the store the Guy got it to bootloop if you can at least get it to do that you can work on unbricking it further

Something like this happened to me when I did a battery pull. My battery wasn't dead at the time either, it had 37%. I ended up sending mine to LG for repair or if you have AT&T, you can get it fixed through them.

I have the same problem, mine just stucks at LG logo and then loops, i don't know what to do, please somebody help us!

Hold down volume down plus power until it goes to the factory reset screen. Press power to "reset" which really takes you to CWM (if you're rooted and have CWM installed). Then from CWM, do a factory reset/wipe data, then flash the zip/gapps (for CM 9), or another ROM if you prefer.

Agree with kernelpanic. Sounds like a hardware failure. AT&T also has device support centers in certain locations that can swap out your phone in some cases.

Hi! thanks for answering!
Yes, I have CWM installed, when I try to enter with volume down and power, it ask me to click power twice to confirm (as usual), but then when CWM is going to boot, the phone resets, and loops again at the LG logo.
I already tried the unbrick method used here in the forum, but I have a problem with the R&D Test Tool, because when I try to click at "Upgrade Start" in CSE web upgrade test, the program opens LGMobile Support Tool, instead of the screen of "country and language", and finally, when I try to update via LGMobile Support Tool, it doesn't found my device (already put in Download Mode in USB), I don't know what to do, please, any information will be greatly apreciated.
Thanks in advance!

Plug into PC. Let drivers install..then reboot boot loader. Type fast boot devices and see if your device is recognized. I am thinking your PC isn't seeing your device.
P.s. I think you may have "cross contaminated your boot IMG. Are u s off...unlocked? Need more info!!!

If your phone don't reboot without a boot loop... Hold power and volume down for about 7 mins. I am also thinking u flashed a bad zip. Let us know if it boots after holding that combo for 7 mins. I know its a long time...

Phone Stuck in Boot Loop (SDS?)

Hey Guys,
I was playing Boom Beach on my commute this morning (which is slowly taking over my life) and my phone just randomly shut off. This has been happening a decent amount when I had multiple apps running after the latest update. This time however, when it got to the "Samsung Galaxy Note II" screen it would try to boot up to the ATT screen, fail and then restart.
I've tried pulling the battery, putting the phone in the freezer and, as a last resort, went into recovery mode and cleared out the cache and the deleted all of the user data....no dice. Now it just gets to the "Samsung Galaxy Note II" screen and either loops or just hangs there.
I am under the assumption that I am screwed here and was wondering if anyone had any ideas on how I might fix it. I think my only shot is to flash a new firmware from the recovery menu...does anyone have any tips on how to do that? Just get me on the right track I guess
Thanks a million!
-Erik

This seems to have bricked my phone completely. It won't even turn on and can't manage to charge the battery without freezing. Thank you for trying to help me out with this, it was much appreciated! I'm very excited to never buy another Samsung product again and get a phone with this cool thing called build quality. Bye bye cheap plastic, clunky interface and slow performance!

[Q] twrp issue and boot problem

Ok heres the deal. my daughter got ahold of my kindle. we i dont know what she did but she ran something that much i can tell. i powered it off then back on. when it booted, it booted into twrp and ran a recovey script. this is where it hangs up. so i held the power button down to reboot. when it rebooted it boots back into twrp. but it boot to the main menu. i rebooted the kindle though twrp. this time it boots up normal. after it is booted up it shuts down and reboots into twrp back the the recovery script page in twrp and hangs up. i have tried wiping the cashe and dalvick, then reintalling a back up. but the problem is still there. if some one can help me that would be great. it does charge so i got one good thing going for me. if worst comes to worst, i guess a factory reset and then redoing all the work i have done in the past.

Was just stock?

the update requires a compatible recovery to install, if recovery is not compatible, it will get stuck in recovery.

ok so i tried to mount sdcard. it was a no go. was following your vid. my kindle just isnt responing like it should. its geting stuck on simulating actions. not sure what that means. i guess its time to start from scratch. now to remember how to format the kindle to factory. any ideas. haha. i do have a fast boot cable. i could try that method, but you download isnt working right. the codes dont match in md5.

How do you hard shut down and then get into recovery?

I got stuck at the boot screen with no OS installed.
Google is finding me ways to reboot but can't find anything on how to do a hard shutdown from here.
EDIT:
Okay one suggestion was to plug the phone into charge, then force a reboot (power + both volume buttons held down 10+ seconds).
Then when it shuts off, you disconnect the power cable after seeing a "battery" on the screen and the tab will remain turned off.
That did not work for me with computer data charging cable.
But it did work with the stock charger. :good:
This helped me get into download using the download mode button shortcuts. But I can't figure out how to get into recovery mode from here? The recovery mode buttons don't work (volume up + power + home).

It looks like this thread has the answer on how to get into recovery mode again.
Too bad I didn't find it before I did an ODIN back to stock.
http://forum.xda-developers.com/galaxy-tab-s/help/to-event-soft-brick-disaster-t2838473

Actually its even easier than that and have done it countless times.
Next time just hold POWER +VOL DOWN + HOME. As soon as the screen goes blank change to VOL UP whilst still holding POWER +HOME.
Works every time to get into recovery.

Confirmed - this worked for me. Thanks!

I'm in the same situation where all of a sudden my tablet went into reboot and got stuck on the logo screen. I tried the combinations suggested such as : Power butto +Volume down then Volume up when screen is black to get to reboot mode but it just brings me back to the logo screen. Is there some other way I can access the safe mode or recovery mode to try and get this thing working again? I wasn't running any apps for it to cause this either, just checking email. Any help would be much appreciated

You're not following the instructions properly. Read post 3 again and hold ALL 3 buttons until recovery boots.
Do not let go of any of the buttons until you see the recovery screen.

Well, downloading is not the recovery.
In download mode you would use ODIN to re-flash the firmware from a computer.
In recovery, you would do a factory reset to reset back to defaults to see if that helps boot back into the existing firmware. You'll probably lose everything.

Yeah I just figured out I was in the wrong mode. I couldn't get it to the recovery mode for some reason but eventually it worked. So I have to go into wipe data/factory reset option? There's nothing else I can do on that screen to fix this without losing everything? I see other opions to Wipe Cache, reboot to bootloader, reboot system now etc..

Well, you're not really giving enough info for us to properly help you.
If you have stock recovery then you can try clearing cache but it probably won't fix a no-boot situation.
If you have TWRP recovery then you can try clearing cache and dalvik and fix permissions which probably won't help but gives you a better chance.
Also, if you had TWRP then you could simply re-flash your ROM zip and not lose a whole lot.

Sorry about that. It's like I said, I'm not too inclined on this type of stuff. Here's what I got and hopefully it helps you more. The tab is completely stocked, never rooted because I wouldn't even know how to do that really. I was on it fine last night and all I did was put it down for literally 30 sec to get something to drink and when I came back it was stuck on the Samsung logo screen. Only apps I had open was gmail, chrome and a word document. There was nothing dowloading, system wise or apps. It's already had Lollipop on it for a week or two and I didn't get any update notices or anything. So I'm guessing the problem is it's somehow stuck in a "boot loop" from what I found searching on google and I don't understand why or what could be causing it so that's the issue I'm trying to fix. I can't get past that screen no matter how many times I restart it. Does that help some?

Yeah, so unfortunately your options are very limited and you're kinda stuck with losing everything.
Try clearing cache first but I doubt it will help.
Then reset to factory defaults. That should work and you probably lose everything.
If not, then search this forum for "ODIN" and "firmware" or let me know and I'll guide you when I get back to my computer in a couple hours.

The factory reset should not touch the external SD card at all. So no worries about leaving it in during that process.
Yeah, starting over.
As long as you're doing that, this is a great time to flash a rooted ROM so you can install Titanium Backup and do regular backups of your apps in case you ever need to reset to factory again.
What model tab do you have? Like, mine is a T705.
If it's an LTE tab, who is your carrier?
The ODIN process depends on this info.

Who knows, something is not happy though.
You could try another reset.
Is your battery greater than 50%?
Under a certain percentage, the battery savings feature could possible do weird things.

Lol yea no kidding. The battery has been plugged in the whole time. I'm actually at 100% now. I was really trying to avoid having to bring it to Geek squad. If I do the reset and it does it again, will going to the download mode and doing the custom OS help at all?

Unless it's a hardware issue, then re-flashing the firmware via ODIN could definitely help!
You can ODIN the stock, unrooted firmware or you can ODIN a TWRP recovery and flash any ROM you want for your phone.
Would still need to know the model # I asked for a couple times above.

Okay great, so you can ODIN a TWRP recovery and then flash a nice ROM. Same ROM I use on my phone. It's stock Touch Wiz that has been rooted and some small things have been improved. Very stable. IronROM.
Or you can download the stock firmware from sammobile.com and ODIN back to stock.
