I always had the LG logo on screen during my problem, otherwise it was the same.

-Remove the mSD and check whether it's still writable on the pc. Operations may seem successful, but remove and reinsert the card to check whether it worked!

-I could no more Fastboot to work since Win8.1, not with stock and not with custom roms. ADB seems to work, though, and Download Mode.

-After reflashing stock rom I rooted it with Kingo Root, and flashed TWRP with the Flashify app on the phone, flashing under Android is the only solution, or use a pc with Win7. For my other devices Fastboot works under Win10.

sorry but i dont know if my bootloader is unlocked. :( sorry so noob here. maybe i can install the firmware kdz because i can go to download mode. the pc also can be detect my phone. what will i do now? thank you

i'm using LG-P768.
[LG Optimus L9 P760, P765, P768, P769] .:xplosiv::.:
So, what I think is this: "As long as we do not do anything that anyone suggests, or until they learn to do it, then we are all noob !!" So do not worry, I point to do what you've done because I also found I in the same situation! Your device has gone soft-brick, and at this point we can solve this problem by installing a right KDZ, maybe up to date than the one that your device now, but still no brand ... better one open. I'll give you a guide that I used a few months ago, and I've adapted to my needs, but I'm sure it's good enough in your case. If you win7, even 64bit, it works great, but it also works with win 8.1 ... while win10 do not know why I do not use it! Once restored the operating system, if you have unlocked the bootloader you should find even with p768 rooted, however, if the bootloader is locked, you will have to do with the root iRoot PC or IRoot Android ... so try and follow this guide all the steps, without neglecting anyone! Ok? if you need help please ask ... I'll help you gladly!

This is the guide

P.S.:

I forgot to tell you, you can then do the flash TWRP or through Flashify, or by using the .zip file that EdwinMoq has released, using ADB, but this method, for those not so practical, can be more nerve-wracking! Do not worry and works quietly!

How did you install the ROM without an SD Card? This twrp only mounts the external SD card and every time you do a factory reset the internal storage is wiped. How did you install the ROM then, using ADB sideload?
[LG Optimus L9 P760, P765, P768, P769] qweewq22:
twrp 2.7.1.1

full wipe

adb sideload rom

adb sideload gapps
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Try this:

1. Copy framework-res.apk from /system/framework to the PC.

2. Open the framework-res.apk file with Winrar or 7zip and replace the storage_list.xml located at /res/xml with the one attached.

3. Replace the framework-res.apk file in your phone with the modified one and set permissions to rw-r--r--.

3. Replace the init.u2.rc and fstab.u2 files located at the root folder with the attached ones and set the permissions to rwx-r-x-- (Read, write and execute owner, read and execute group).

4. Reboot

[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Did you check with more than one SD, whether the slot is broken?

The broken mSD during my install of this rom would no longer be detected by the phone, but appeared fully functional under Windows at first, would read and even seemingly write or delete w/o errors, though all modifications are gone after a remount, as it had lost writing capability. So the card, which I was about to put with the others for further use, has to be sorted out to avoid similarly vague problems on other devices later.
[LG Optimus L9 P760, P765, P768, P769] Codeplex:
The problem you had of broken sd card is not due to the rom installation, many people faced similar problem in many different scenarios, I also faced this problem a while ago while i was creating a linux bootable USB, sometimes this problem appears while partitioning the cards, same kind of problem happens to USB drive also, Main reason for this kind of problem is when partitions got damaged, sometimes memory cards & USB drives behaves in a weird way you don't even think of. There has not been a permanent solution to this problem also there are many utilities available on the internet for for SD cards and USB drives. Just google them also try using sdcard adapter with lock unlock switch and try to format with it may be you succeed in repairing your broken sd card.. :)
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
The card has been dumped. I only mentioned it in case this is another such issue, and the phone is still fine. Which would be preferable.

Maybe mSD cards have some software lock switch as a replacement for the mechanical one of fullsize cards, and this got triggered. But then, neither Windows nor Android can properly show or alter it.
[LG Optimus L9 P760, P765, P768, P769] qweewq22:
i extract system, and edit them... but without root, i don't put files in the phone

iRoot, Kingo ROOT, LG One Click Root = no root

can you do ROM with root + twrp (2nd load from system, for locked BL)? then i replace this file ;)
[LG Optimus L9 P760, P765, P768, P769] kjoe07:
if you have acces to /system then you have root access. i guess you are in this rom but dont have external sd so did you enable developers options it has administrative access so you can enable adb and aplication and when root is neede it will ask you about permision for app. tip to get developer option tap 7 timen in compilation number, it will enable developers option, so no rootin is needed for this rom 5.1.1

will cm12 be discontinued?

another question...

can rom flashing kill a battery?

tried MIUI, then cm13, reverted back to cm12, charged the phone, woke up, fon dead, charged, but never got full...

can a battery suddenly take a **** like that in one day?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Since the release of CM13 there aren't many updates to CM12.1. I might update it if there's any significant changes, but I will focus on getting CM13 to work.

As for the battery, I have no idea. Was the battery in a good state before?
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Bugs I discocered in CM12. 1 so far:

-Swiftkey keypress sounds are dead, but vibration works, so this will probably not annoy many folks, except myself.

-Bluetooth: Streaming and keyboard profiles work. Monaural headset and handsfree profiles just generate crackle and hiss sounds.

Hey I noticed a bug on your latest build. When I let my battery drain and I go to charge it, it's not showing it's charging. I think it's charging because the battery percentage isn't changing. However, when I reboot the battery is charged some and the charge indicator is working again.

waiting out traffic right this second..

Otherwise, this ROM is friggin awesome.

Fully charged at 930 this morning and got about

15% left on a bad battery (swolen) with light to moderate use

Nevermind about flashing the radio, open signal 4.4 mb up n down

Ookla speed test 12.7 mb down 4.4 up. in my friend's basement

MMS, text working back camera works but switch to front and It

crashes and stays crashing until wipe app data.

Just iron out the little bugs like GPS not locking and the camera

and this'll be the best thing out there for a while.

Would Xposed modules work on this ?

Are they compatable?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Why do you want SuperUser anyway? CM has a privacy guard menu where you can manage root access of apps. Just enable root in developers options and reset permissions at Settings -> Privacy -> Privacy Guard.
[LG Optimus L9 P760, P765, P768, P769] .:xplosiv::.:
GPU rendering and response of the CPU, seem to be successful, the only problem is the fact that I could not do flash Xposed framework by Gammerson downloadable from here .. . any of you have tried it and had positive results?

It worked for me flashing this version with TWRP

After a reboot there was no signal at all for some time, before the phone went straight to HSPA+. Was the whole matter caused by 2G service failure, the phone being innocent?

Verify that the SD card aint broken.

To do this either try to format it on the PC, or try to copy or delete files via USB. If it's no longer able to write, file operations will seemingly be successful in Windows explorer, but upon reboot or reattaching the phone or card, all modifications will be gone, cos they only happened in the Windows file cache. Error messages will only appear when attempting to format.

What method did you use to flash the stock ROM? This is very weird, if the phone is stuck at the logo that means it can't even load the kernel, which isn't normal. Do you think it may be a hardware issue?
