sprint lg g2 rebooting constantly - G2 Q&A, Help & Troubleshooting

Guys can someone help me? I have a sprint lg g2 that was flashed with a tmobile stock via lg flasher or something and it was then flashed with sprint stock rom on it(that failed)...so, now its on a t-mobile rom but, it reboots every 10-20 secs....I have managed to re-root it again, but having trouble flashing custom recovery on it. also, now it doesn't show up under adb devices anymore...but, I can get it into download mode, can I still save it? or all is lost?

so, I finally flashed CWM onto it, so can I just sideload a rom?

[HELP NEEDED] LG G2 D802 won't boot and in download mode it says model is F380K

Hi everyone,
I am having issues with this phone of mine. Here is a background of it:
My phone is rooted and is running rayglobe rom. I tried updating the update that it gave me and made me stuck in bootloop.
Now I downloaded another rom, which I don't remember since this happened december 2013. after flashing, it does not boot and does not make me go to TWRP anymore. Now I tried using download mode to restore my phone. but eveytime I try to flash (using the 2 methods I saw in the thread), either it hangs at 49% or the other one does not start flashing because it says I have inconsistent dll? I downloaded a D802 stock rom and tried flashing via download mode and it says that I have different model (F380K). Now I tried downloading a dll and F380K stock rom, but won't allow me because it says that my phone is D802. But when I go to download mode it is korean and it says F380K.
I think I have flashed a korean rom before which made this incident happen, but do you have any idea how I can restore this?
Thank you all in advance.
If this was me, I would do a factory reset.
sounds like you should go back to stock firmware.

First check what exactly phone model in Internet Browser. Then download TOT and flash back to stock.

I faced similar problem with D800. I had the correct dll and the firmware but it failed saying my phone model was different (I think its because I tried the "upgrade recovery" option on the LG PC software by selecting a different model).
My phone was passing the LG screen and stuck at android boot screen.
What I did:
Pushed a kitkat based rom for D800 to sdcard using adb on Linux (on windows adb failed to recognise the device).
Then adb reboot recovery and flashed the rom.
Then I was able to flash the factory image.

Help w/possible bricked G2!

Folks,
I gave my rooted (mahdi rom) ATT G2 to my teenage son seeing I was no longer using it. He said he tried to update the Mahdi ROM and now it is bricked. From my questioning him all I know is when he was installing the mahdi update, but he did not flash the D800 patch. Noticing there was a problem I think he tried to re-flash recovery or something. All he would get is "fastboot mode".
I think I am a pretty smart guy and have been on XDA for years flashing and what not with no issues - but this one has me stumped. These are the steps I have taken:
1) Finally got it into download mode and when I try to flash the tot file for ATT, it says incorrect model. Says the model is the D801 (t-mobile)! I was like what?
2) So I tried to flash the D801 tot and it seemed to work, but the flash would ultimately "Fail" in the LG Flash Tool. It would boot up into the t-mobile rom but I would get errors and reboots - very unstable. AND the IMEI was wiped!
Does anyone have any ideas what I can try next? I would like to somehow change the model back to the D800 and flash the ATT tot file. Maybe it is truly just bricked!?!?
Any help would appreciated! Thanks!

if you can successfully root device with towelroot(best choice since it is not device specific) then your best bet is to copy d800 build.prop(or to play it safe edit the build.prop model number from LG-D801 to LG-D800) into system/ give it rw-r--r-- pemissions and reboot into download mode, it should say you have d800 and you should be able to flash back to d800 tot(might want to be using d800 dll that ignores model check too just in case)

[q] g2 d802 big problem

I'm not able to flash any more custom packages (rom, mod, kernel...) on my phone even with custom recovery. now every time I flash a zip file, my phone gets stuck at boot screen. I 'm not a newbie, I have been flashing phone on different brands and G2 for 3 months!
It happened after I flashed a wrong kernel version on my D802 (D800 instead). so I used LG support tool to get back to life, and the phone is fully functionnal. I can still root nd and install custom recovery, and even after flashing, I have no error message.
Any ideas?

[Q] No recovery after flashing stock rom? LG G2 D802

Hey guys, I've been having some issues booting into recovery since flashing the stock rom back onto my LG G2 D802.
My phone had been rooted and was using TWRP as it's recovery tool. However, I wanted to unroot and go back to stock on this phone so found a guide in order to do so.
I followed the guide exactly as it is in this thread and completed 100% but now when trying to go into recovery mode nothing happens, the screen just goes black and just reboots itself.
Does anyone know if and how I can get the stock recovery back onto my phone?
Thank you in advance
