[Q] Optimus G (e977) problem - HELP ME!!!

Hi guys
I'm totally new here. So, if I'm in a wrong section please let me know.
At first - This DUMB here, won't made a backup. So I'm f**ked
I have a E977 phone and tried to flash a rom (bootloader unlocked and recovery ok.), but something went wrong... and when I try to boot, appears the LG logo and a black screen... that's all. But I can notice that the phone is on that the rear was getting hot and the battery decreasing (I can notice that when I plug in the charger).
And when I put in the charger, appears the battery charging and then this screen in attachment
Can you guys help me? Please
Oh, almost forgot: I'm brazilian, so my english is really BAD. If you won't understand something, tell me.

I can't see the pic because I am at work and it is blocked, but what cell provider is it from? I can't find E977 anywhere. I found e975 but they're not the same. There are a ton of brick fixes around that flash a recovery and let you flash a new ROM.
2 main questions I have that might matter to me.
1) What recovery do you have installed?
2) What ROM did you flash?
From what I read, the e977 is the same as the e975 with a different LTE band, so you might be able to use the info from the e975 and then flash the correct modem on yours.

Read it all, there's a lot but I am sure someone with an e977 has had the same issue.

[Q] LG G3 stopped

My LG G3 stop to work, i touched on the screen but no answer just the LED flashed. I had to remove the battery, but when i turned it on just displayed the LG screen and stayed there. I changed the rom using flash tool for Lollipop, the cell phone turned on but song and some apps didn't work. I tried to install Kitkat version again, but it did work. The kitkat rom dont start on my cell phone.
Another problem is i have to keep my screen on all the time, if i do 2 taps on screen or press the on/off button the screen get off and nothing can make it on, just taking off the battery and turning on the cell phone again.
Please people help me. I know you are the best in the world and anyone here in Brazil could help me.
Sorry about the english i don't have a good one.

[Q] LG G3 Security Certification Error, LG Flash Tool Not Working. HELP!

So I rooted my D850 with LG_Root and it worked. I wanted to take it a step further and install TWRP. It didn't work but the system still worked and everything. So I did a little more research and found that you need to use BUMP and you need to install a patched bootloader and version of android. I did and its completely bricked now. Well not COMPLETELY. When I turn it on it gives me a message saying security certificate error. Then it goes to a black screen with a blinking LED. I have to remove the battery to get it to turn off. I can get it to download mode so I tried flashing with no success.
I bought it at BestBuy and I'm past my free 2 week warranty by ONE day. So that sucks. Luckily LG has a 1 year warranty. Will they replace it? It says they only replace/refund/refurbish HARDWARE failures, etc. Should I dump some water in the USB port? Lol.
What should I do?!?!?

Don't jump the gun just yet. Can you give more detail on trying to flash it and not suceeding? What exactly did you try? What happens?
If it goes to download mode, its probably repairable.

FIXED

Hi.
If you have tried the Hard Reset and it did not work then I have to ask you if you are still under shop or LG Warranty. If you are take it back.
It may seem obvious to you my reply but it is so. If you can return it you do not want a problematic phone right?
However:
If you do not have the Warranty any longer then your best and perhaps only solution is to flash with a computer <preferably windows 7> a KDZ or TOT+DLL file. This will flash the LG stock firmware back into your phone and eliminate this issue and make it like when it first came out of LG factory.
Be careful to READ and understand very well this process. YOU MUST choose the correct KDZ or TOT file for your model. If you flash the wrong file for your model...goodbye LG G3! Do not be in a hurry until you completely understand the whole process.
Below is a link to an XDA thread where you will find LOTS of help in doing this. The OP of this thread @hyelton is a really nice and helpful guy and has helped thousands of people. Just head over to the thread, first READ the OP and then post your questions and you will get help.
If you have no Warranty do this. Be patient and YOU WILL get your beloved G3 fixed.

[HELP] Hardbricked G3... :(

I am Done.
It's not booting, it shows LG splash screen and after some seconds dies.
I tried everything...
my last resort was using LG Flash Tool and flashing the .tot file...
First time, it went good, even reached where the 2 Factory Reset Status, where it froze though. Followed a guide saying I need to select Board DL, tried but no good.
Now, when trying to flash again, and reaching where the phone has to reboot, it shows the LG Splash screen and dies again, sometimes, it shows the Demigod Crash Handler saying either Kernel Crash or Tz Crash.
No one seems to want to help ...
