[help] stuck at the lg logo, no usb-debugging - LG Optimus L9 P760, P765, P768, P769

Hello.
A friend of mine didn't touch his phone for about half an year and when he tried to boot it, it just stucked on the logo.
Hard-reset doesn't work.
And I can't flash kdz because usb-debugging is off. Flashing stops at 50% with "problem with communication".
Is there a way to fix it?
Sorry for bad english.

It is not my phone. And the man who owns it has no idea about android and version of it. So I don't know it.

Do you have any recovery installed on phone?

You don't need to send it to LG service. You just softbricked your phone. Try this: http://forum.xda-developers.com/showpost.php?p=40483954&postcount=2

emergency help to get into recovery mode

Im new in android rooting. I flashed CMOD13 into my LG G2 yesterday night. But the phone showed me I don't have root access. I don't know there is a root access in the developer options ( it's too late to let me know about it ), i rooted the phone again by using one click root and it didn't success. Now it's stucked in the cyanogenmod logo and never turn into normal boot after 4 hours. I cant even get into recovery mode. Anyone can help me to solve this problem? All I need is just get into recovery mode, then I think the problem may be solved :crying::crying::crying:

Phone won't boot after updating SuperSU

I need help immediately cause I am paniking. So I rooted my phone using the KingRoot application, and after the root was succesful used SuperSu-Me to remove KingRoot. SuperSu-Me installed SuperSU on my device which in turn had to install an update, so I let it do its thing. After the update was installed SuperSU prompted me to reboot my phone so i did. Problem is the phone has been stuck for about half an hour in the shifting shapes screen, fastboot doesn't work. I have tried hard reseting it but the problem persists.

My solution
I fixed it by unlocking the bootloader in fastboot mode, flashing TWRP and using it to flash the original version of the oxygen os, the one that came preloaded with the phone.

Help me pleaaase (( My phone is very important to me. I've been searching for forums and I only found yours that had the same problem with me. By now it's about 1hr just stuck in there ( please help me im begging you!

First, please don't follow instructions you're finding on this specific forum since it's for the OnePlus X, not the Starmobile. Secondly you needed to unlock your bootloader first, since you didn't from the sounds of it you can't boot into Android since it's now tampered. You'll need to boot into recovery, usually by pressing Power + Volume Down until it loads and factory reset your device.

Try to find out your solution in your device's forums, since this forums is for the OnePlus X and not the Starmobile Knight Luxe.
If your device is stuck on the bootup screen, you need to go to fastboot mode, unlock the bootloader (if you haven't), flash a custom recovery, boot into the recovery, and factory reset the device. It should work.
Guys!!! Thank you for all your suggestions. I did flash a custom recovery but it fails simultaneously. I just let it fix on a local phone repair shop just paid a few bucks
