[Q] LG e975 won't boot, stuck on logo of LG - LG Optimus G (International)

My new phone had been arived a few days ago, i want to install cyanogenmod 11 (kitkat) on my phone, so i installed the nightly buil.d
After that i found a big problem, the phone doesn't detect my sim card (european card), so i have flashed my phone back to stock. That is where the big problem started, the phone won't fully boot anymore. It stucks on te animated LG logo, it doesn't go further.
I tried to solve this by reboot, reflash with original LG software (not a KDZ file as in the first try), but all doesn't work.
The problem still occur.
Can anyone help me to solve this problem?
Your sincereley,

13.Q: I tried custom roms, now I want to go back to stock. How do I do that?
A: Use kdz updater. HERE (http://forum.xda-developers.com/showpost.php?p=44874388&postcount=36) is how to use it. I made simple. Original thread HERE (http://forum.xda-developers.com/showthread.php?t=2010624). IMPORTANT : IF YOU GET STUCK AT LG LOGO AFTER USING KDZ UPDATER,YOU NEED TO PERFORM A HARD RESET. After this,the phone will boot.
Hope this helps

this here is very common that ppl don't wipe and hard reset their phones after flashing stock rom comming from a custom rom, even i forgot that the first couple of times :victory:

OK, my problem was Windows 8.1... The phone is well recognized by LG Tool under W7, but now I have another major problem, at the last step, when the tool begins to flash the rom, it goes until 5% and then this popup box blocks the flash "battery level is low and upgrade is unavailable"
I have reload fully my battery (I plugged it into the G PRO dock)... still the same message.
Any help please ?
Did you manage to resolve the issue? I am just having the very same problem and a bit lost and cannot risk flashing anything right now.

Hello, I would appreciate your help because I flinched and my tel ugly now this only in the LG logo screen. I wanted to update my original rom Phone factory and downloaded the latest version before upgrading but I did not wipe data and When there finished the process gave an LG IMS error stopped working this type, and there Could not get into hard reset on the way, OK up here but then I Decided to reinstall the rom again to see if it would correct the error and then I installed the previous version I had downloaded it and my phone is so in the logo screen. If I try to instal the updated rom, would be more risk? And I wonder if I can not like the ace debugging would access via adb and make wipe data factory reset only by simple USB connection? I can not I do the code by turning the volume down and holding power button goes not into hard reset the screen goes black and comes back on the LG logo... Pleaseeeeee help meee!!!!!!

LG G3 Stuck in bootloop after Flashing Stock Rom

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!
I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

The data should be safe

Help my G3 might be hardbricked (hopefully only softbrick)

Hello, I would like to ask if my LG G3 is softbricked or hardbricked. It has been a long while since it decided to boot loop. I tried to fix it but got no results. I tried to factory reset it, but the next day it didn't turn on anymore and got stuck in the logo. Note : the phone was experiencing some heating issue before it decided to screw itself up. I tried numerous troubleshooting from the net, none worked. I also did try to reinstall the firmware to stock again, it did boot but it can't get to the home screen. I then factory reset it again and tried using another firmware also built for my phone (it's LG G3 D855). It failed again at 33% while it was in the firmware update mode. Now that I have left it for a solid year, I thought that it would be nice to try again. Which I did, but it couldn't charge anymore and it cannot boot to the logo. I tried to go to the download mode but no response. I tried connecting it to my computer, but it only detects my phone as a charge only device, it also detects it on only several random occasion. I hope this is a softbrick and it can be fixed at home so I don't need to go to the store to repair it.
I'm sorry for the long explanation, I had been trying to revive it for months now and had no luck. How do I fix this, at least how do I get to the firmware update download mode again? I really really hope that anyone can help. Thankyou so much in advance.
