Have you tried to change the battery? Do you have a memory card installed ?
Also have you tried the adoptable storage option?

If the problem comes from the Custom ROM , the ideal would be to flash the stock ROM using LG Flash Tool (2014)
Here the thread where I downloaded the stock ROM I am using now: [LG G3] Android Marshmallow discussions
There are many tutorials and videos on Youtube. So you can try to flash it.
You will lose root but if you really want it, you can use this tutorial to root the stock Marshmallow: Root + TWRP Marshmallow D855 (30b)
Try this and please tell me if it solves your problem or not .

what i downloaded is also a stock ROM
no sorry the computer wont recognize My phone and the phone wont go to download Mode

i tried to plug out the battery and connect the Phone to Pc he recognize him but says there is trouble connection
so Waiting some hlep Guys
thans for every help

any help pleaaase ??

Potential downgrade issues ( from 5.1.1 to 4.4.2 )

Hello,
Since we are all still stuck with this partially functional root on our dearly beloved SM-N7505 on 5.1.1 , i started considering downgrading it to 4.4.2 ( last version i had root fully functional on ) .
I wanted to know if there are any risks I might come across during the process and what should I do before hand
P.S : One of my friend lost his IMEI due to the downgrade on a Galaxy S3 (which was a pain on the ass to fix)
Any info are welcome, i need to know as much as possible before i proceed
Many thanks

NO bro there will be no problem to downgrade, just download rom zip file from here - http://www.sammobile.com/firmwares/database/SM-N7505/ and follow the steps :-
1. Extract (unzip) the firmware file
2. Download Odin v3.10.7 (http://dl.sammobile.com/Odin3_v3.10.7.zip)
3. Extract Odin ZIP file
4. Open Odin v3.10.7
5. Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
6. Connect phone and wait until you get a blue sign in Odin
7. Add the firmware file to AP / PDA
8. Make sure re-partition is NOT ticked
9. Click the start button, sit back and wait few minutes
congratulations you have downgraded your mobile!

no problem in downgrading from 5.1.1 to 4.4.2. but you should remember that after flashin 4.4.2, you may need to enter recovery, and wipe data + cache, or else you may face bootlogo stuck

GT N7100 no start error. No recovery. No Logo

Hello. I have been using Note 2 GT N7100 for over 3 years now. Have rooted the phone and was running a Crdroid custom ROM on it. It did not give me any problem. Nor did I update the ROM since it was running good.
Suddenly yesterday it got stuck on the Samsung logo. Tried restarting it, but it didn't move ahead of the logo.
Today, it shows a grey and white screen. Fully blurred and can't see the Samsung logo too.
Tried going into the recovery mode, but same grey screen appears.
If I take it in download mode, it goes there. But when I try to install any stock ROM, it doesn't work. It shows failed in Odin.
Please help what can be the possible problem?
If any more information is needed, I will provide it.
Any ROM to install or custom recovery?
Please guide what to do?
Also, I am sorry if there is already some post like this. Please let me know
Thanks in Advance!

Need a valid link for Recovery Package
[I moved this post to this section that's more apropriate http://forum.xda-developers.com/showthread.php?t=2154890 ]
Hi guys,
Is there a link for the Recovery Package/ROM ? (the one above doens't work)
My phone is stuck on the boot logo and I need to fix it... (I'm a bit noobish..)

Are you able to be in the download mode for some time? Try to use DLM backup using lglaf to backup all your partitions.

I would find the stock firmware that you where on and try to flash lgup or flash tool and start again you will lose data but device will be working. And remember to always backup before hand.

First of all thanks a lot as your method perfectly worked , i just have another question out of curiosity if you don't mind , altough LGUP did work of course , i recently noticed that if you don't already have the Google account already registered on the device , and precisely on Lollipop and above , there's absolutely no way you would boot up your phone , i wonder if there's a way to bypass that Google Verification thing !

and just for reference , LG UP doesn't entirely flash the device , it just .... , you know , like just replacing the old firmware without deleting the data , LG FLASH TOOL 2014 doesn't work either , it doesn't even start the flashing process regardless of the firmware , so it's not an option .
