Phone restarts 20 seconds after opening. Sprint LG G2 - Sprint LG G2

I recently flashed the 1.6.1 furnace kernel and my phone began to act strange. I did not deviate from the instructions and took precautions. The phone would turn on and seem functional for 20 seconds. After that, it would turn off and restart. I flashed the stock rom and unrooted the phone, however, it continues to behave this way, only now it isn't rooted and I cannot access the recovery menu.

Is the Kernel Undervolted/Overclocked by default? Some custom kernels are UVd but not all phones can handle that.

I don't believe so. I chose the non overclocked version to be safe so it should't be. Is there a way I can flash a custom ROM onto the phone without recovery mode and without it being rooted?

You can get back to stock via download mode, but I don't believe you can install custom roms.

Will this change the current kernel back to stock because I think that is the problem. I kdz using flashtool and it works for about 5 minutes before doing the same thing... : (
Should I just keep trying or is there something I should change.
(I have reflashed the stock .tot before and it worked. Using the same method now doesn't seem to work)

Take it back to stock with download mode. If this does not fix the issue then the phone needs to be replaced. If going back to stock doesn't fix the issue you might want to work with the developer as I have heard of this before. Might just be faulty hardware as it doesn't seem common, but there may be something the custom rom is doing that is the cause. Hoping a factory restore fixes things for you.

[Q] Is it possible to go fully stock with out using Odin??

the tittle says it all. i want to go stock to take it back to sprint. b/c my phone is defected. my phone cant tell when its connectedto my computer.. it just keeps charging and never gives me an option to use the usb mas storage. yeah i tried changing cables, using different computers, disable usb debugging, tried different roms, tried going to recovery and mounting my storage. nothing works.. my phone works perfectly with a custom rom. however, I cant connect to my computer.. my phone is not bricked it just wont connect to my computer. so im trying to go back fuclly stock with out using ODIN.. (FORUM PLZ HELP)
Not sure why you have 2 threads about the same thing.. but anyways..
You might want to try out Mobile Odin
https://market.android.com/details?id=eu.chainfire.mobileodin.pro
It's $3.99, but well worth it.. I think anyone messing with custom ROMs and rooting their phones should have this just in case.
I'd actually like a youtube tutorial on this same process. Mobile odin confuses me a bit after using pc odin for years on my vibrant.

You can technically create an update script to flash via CWM and flash everything but the bootloaders...
there are some more advanced ways to flash bootloaders manually.. but I wouldn't recommend it unless you REALLY know what you're doing.. You can brick your phone, so it's not even worth it. I'm not sure they can even see the bootloader version anyhow, so it doesn't really matter.

You don't need root access to flash the kernel, since you would still be on custom recovery. So yeah flash a stock unrooted rom, then proceed to flash a stock kernel with stock recovery.

Or if for some strange reason it doesn't work in that order just flash the stock kernel first (it won't change until you reboot) then flash the stock rom without root.

So the only close enough to stock rom that i found is this one should i use this one ????? damme this is a headache http://forum.xda-developers.com/showthread.php?t=1415924
You could also use terminal emulator on the phone and run the script from sfhub thread (http://forum.xda-developers.com/showthread.php?t=1342728) to install stock EG30+stock recovery, and run unroot script straight from the phone. Then just use file explorer to delete the 000root directory.
Since your phone wont recognize the computer you can always copy the files over by using a sd card reader.
So i went to the sprint store...and i told the tech support guy that my phone was not connecting to my computer and he took a quick look at my phone and said did you rooted??? and i frozed and he continued, if you rooted your phone then thats the problem. i told him that it was more of a hardware issue not a software...he wasnt even paying attention to me.. he just said stop messing with the phones if u dont know how to how to fix them.. i was so madd i felt like throwing him my phone at his face.. but then i thought to my self.. my phone is not messed up.. it just doesnt recognize my phone.. plus i got the XDA community..

Wow... i just even did a dial code hard reset of the phone and i'm still having the same issue --- ughhhhhh frustrating
Just take your phone into sprint with it rooted. The first thing they will do is return it to full stock to see if that solves the problem. Sprint's policy is to service all phones rooted or not. Just expect it unrooted when they hand it back.

Hey, I rooted my GS3 and installed cm10, but it was very buggy so I tried to reflash stock. As of right now I can get into download mode and that's it. I tried reflashing stock but idk if I'm doing it right.

Thanks for the quick reply! Through Odin, I've managed to hear the start tmobile sound but the screen stays black.
I'm not really sure what the problem is, but did you use the correct stock rom for Tmobile? And you did it through the download mode by holding down button, home, and power right? Just making sure it wasn't clockwork or twrp.

That's one of the reasons flashing back to stock can be hard. Try flashing the stock image that is injected with a custom recovery (cwm I believe) found in the developers section.
Wiping during this operation is crucial so as not to get stuck in a boot loop

Thanks everyone, here's how I fixed it:
I flashed the stock rom without auto reboot and then pulled the battery.
Then, I flashed CWR without auto reboot and pulled the battery again.
After that, I could get into CWR so I flashed cm10 and a different google apps package than last time.
I don't have any cm10 bugs now. It would crash acore alot and stock apps like messaging wouldn't work.
Thanks for the help everyone, I'm set now.

Lock up and restart alot?

anyone else having this prob. sometimes i will use a app and the screen will go black and unresponsive i can still turn the screen on and off wit the power button but it eventually restarts however it does the startup animations but does not make the sounds. any fix?
some history:
tooks some time but decided to root, once rooted the factory os would not boot. so i did the restore to factory flash with counter reset uploaded by a fellow member of xda and then did the flash to root.
now i have this prob.
What Rom did you flash to? Stock or something else? Also, Root method? Odin CVM, Flash root zip? just trying to see if there's anything that sounds odd or off other then the issue you described. I rooted with CVM Flash (odin) and zip root method.. Flashed The People's rom, No resets here.

I have seen this a few times recently. I did not have that happen when I read on ICS. It only happened after I updated to lj7.
It is interesting to note that the phone appears to restart and recover but when I look at the uptime for android I see that it was not a full reboot.

I'm only guessing but it could be because of that. Some that had the lines already had twrp but had broken download before they used autorec. Like I said though, it's a guess.

I also was rooted on stock ZVC. I installed autorec and let it do its thing. First try, I could not do a backup in TWRP. It would fail everytime. Then I booted to system and thought everything was fine till the screen went off. White lines slowly appeared and stayed. Only fix was to reboot. That got boring so I tot back to ZVC and used ioroot25 to root and then installed autorec. White lines again when screen off then back on. I think waiting until the dev can figure out what is being altered on our ls980, we have to wait.

Agreed on modified kernel.
I hope @Cloudyfa sticks around for us, to help the ones that need it. He has contributed so much to the G2 community.
My big concern is that freegee doesn't give any info as to what version of ZVC OTA it's compatible with, and neither does the autorec thread for that method. Like in the ZVA-> ZVC thread, there's a zip of the OTA... which is slightly different than getting the official OTA through system updates on the phone. So I'm afraid to try either method and end up with an unrecoverable brick because I'm on the official OTA.
Anyone on completely stock ZVC, rooted, that has successfully used either method?

Auto-rec works fine. The modified kernel that every app or by manual has used is the same at the time.
The worst it will do if it does not work is give you lines in your display after the screen shuts off. A reboot fixes that. But to fix completely, is to tot back to zvc and stay just rooted.
