Sorry if this has been asked before I had a bit of trouble finding a real answer.

Will this work on a P769 with locked bootloader? I seem to remember trying this rom a while back and got a messed up screen and error messages

I haven't used this in ages, although, it does work with the locked bootloader. You just need to find the right patch by Kuma for it.

p769 Screen Trouble

So I actually just encountered this ROM yesterday.. It made me so happy to experience CM again in such a really long time and It was so refreshing and of course Snappy. However, I can't seem to be able to fix the Screen issue using the Fix for the Europe Rom. (Which I think is only supposed to work just for v10\20x firmwares)

The Fix is this.

https://mega.co.nz/#!Rt1AGK7K!C4hFml73nKeK5LdsjU9FTCwNyWc28cFR3Qc3APl5Rvk

We need more 2nd init roms like this.. Either maybe someone fork this and improve p769 Compatibility or create something lightweight.

There are some things that have spanish names... But I'll get used to it... I mean it's either this or that slow LGCustom JB.. right?

Flashed it and am successfully on Cyanogen, FINALLY, but, I have the wonky screen issue, and my device is not being recognized by ADB.

Any advice?
[LG Optimus L9 P760, P765, P768, P769] Ilxaot:
This is stable, correct? I don't want to flash KDZ's to my phone to flash this if it's not good for daily use on a locked bootloader.
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
Just wondering; if I successfully got this installed on my T-Mobile P769, after running kuma82's excellent themed ROM for locked bootloaders, can I upgrade to another version of CM10.x, without causing a security error?
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Wow! Any chance of CM 10 getting ported to locked bootloader? This is still awesome! :D
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
I tried flashing this, following all of the instructions to the letter.

While it DID install correctly, and I was greeted with the much-missed Cyanogen Mod screen, for some reason, my PC will not recognize my device over ADB anymore, and I cannot get the wonky screen issue fixed.

So, I did another factory reset, and tried to flash kuma82's ROM back on it. That worked, but the screen is still wonky, and flashing the 20f_u-boot.zip does not fix anything.

I didn't think I could hate this phone worse.
[LG Optimus L9 P760, P765, P768, P769] Daycrawler:
The ROM is insanely fast, thank you!
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
Can anyone at all help me to get ADB to recognize this device? I have all of the proper drivers installed, and it DOES recognize my device when I flash it back to kuma82's ROM.

I am desperate at this point.
[LG Optimus L9 P760, P765, P768, P769] Polloos:
I'm looking to make it compatible with this model, please patience, they have asked me many things and I'm slowly doing.

My updates are long but with many improvements;)

For P769 wait :)

In my PC with Widows8.1 Update 1 the ADB does not work, but if Ubuntu 14, and on my other pc with Windows 7 too.

Do not know why this happens: S

Yes, is stable for day use

No, any modified kernel will give security error.

It is possible, but very difficult. I tried it once and didnt get it working

When I believe that this CM9 is perfect and it has at less errors as possible, so I will resume CM10

It's responded up the P769 model and ADB

Thanks a lot :D

It's responded up the problem of adb
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
You, sir, are a rockstar. I am trying to see if I can map out how to push the commands through Terminal Emulator. This is what it looks like;

ulv/b Above Y Above P 4 kjulbj Above P 4

That translates to:

cat (space) (Toggle123) / sdcard (Toggle123) /

And so it goes. I can get the entire command line of "cat /sdcard/v6.bin > /sys/devices/virtual/input/lge_touch/firmware" typed in on Terminal Emulator. It took me two hours.

I am going to try one more time using that method, adding the line "echo 1 /sdcard/v6.bin > /sys/devices/virtual/input/lge_touch/firmware", and see if that fixes it.

You will be my hero for life if you can get this working on P769. Already, you have done more for us locked bootloader victims than anyone outside of kuma82.
[LG Optimus L9 P760, P765, P768, P769] Polloos:
Try this on Terminal Emulator:

Unzip v6.bin to sdcard

su

cat /sdcard/external_sd/v6.bin > /sys/devices/virtual/input/lge_touch/firmware

reboot
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
That is precisely what I have been trying, but, it doesn't work when I can't get my Windows 7 PC to recognize my device at all. When I run the line "cat /sdcard/v6.bin > /sys/devices/virtual/input/lge_touch/firmware" through Terminal Emulator, even with the wonky screen (pure hell, believe me), it SEEMS to work, and it looks like it pushes through correctly, but after rebooting, nothing changes.

Yet, when I reflash kuma82's ROM, then my phone is detected properly, and I can just run the commands through a command prompt, and it fixes the screen instantly.

So, the fact that we've gotten this far at least gives me some hope. The only thing stopping me from being able to use this new ROM is the mirrored/wonky screen problem.
[LG Optimus L9 P760, P765, P768, P769] Polloos:
The wonky touchscreen is caused by kernel? if so there is an easier solution. Replace the kernel of ICS kernel of P769 .

There is a way to make ADB work on Windows 8/8.1 (wich i do with CM10 and CM11). Search for LGE L2 USB device on the devices administrator (show hidden devices, look for one with a question mark) and manually install an ADB driver for it (Android Sooner Single ADB interface works fine), it will work.

Windows 8/8.1 is full of fails, specially with mobile devices drivers, in fact MTP barely works and with a lot of errors.

Stange thing...

This ROM is strange.

I have flashed TWRP recovery.

I flash this ROM with it without problem.

But this ROM flashed to my phone an other Recovery by Artas.

I do not understand how? And where?

Coz my TWRP is intact!

But when I reboot the phone, after LG Logo, LEDs are flashing, and if then I press and hold Volume Down, then suddenly I'm in CWM 6.0.4.5!!! (I know, this is old Artas's recovery method for locked phones) If I dont press Volume down when LEDs flashing, then phone boot normal mode, and CM9 works...

I think the popup is from CMUpdater, will try to fix it.

I dont have kernel panic, It is very rare ...

Yes there are my CWM 6.0.4.5 in system/bootrstrap. But dont replace the recovery in partition, delete recovery.tar and use your recovery normally
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
I followed the instructions as you suggested. While it does fix the CWM screen, when I reboot the phone, it gets stuck on the LG logo and doesn't move. I tried doing all of the wipes, then flashing the ROM through CWM, then installing the fix. Still stuck on the LG logo for the past five minutes or so.

Going to try dirty flashing the ROM over this, and reinstalling Gapps to see if that fixes it, and will report back.
[LG Optimus L9 P760, P765, P768, P769] :
I am not sure if we think about the same thing. I noticed a bug in reboot menu (this menu show up when we keep power button). Rebooting to recovery does't work (but entering into recovery in old way works perfect). In other cm9 for lock bootlader it didn't work too. For now I didn't notice something else :P
[LG Optimus L9 P760, P765, P768, P769] JulianJenner:

No luck. I tried reflashing the ROM, doing a full wipe, installing Gapps and then the fix that was posted. Still keeps me stuck on the LG logo.

I tried flashing all the way back to stock, then re-rooted, re-installed CWM and BusyBox, reflashed the ROM and tried again, and still I wind up stuck on the LG logo. Going to just leave it here for about twenty minutes and see if it will boot.
[LG Optimus L9 P760, P765, P768, P769] kuma82:

[LG Optimus L9 P760, P765, P768, P769] kuma82:
Well I just found out it has a huge bug, might need to change a couple more files.

The screen doesn't turn back on (pressing power button) once it goes to sleep, have to reboot the phone (hold power button for 10secs).

Hopefully I can find out where the problem is.

If you still want to check it out here's the link

Instructions

1.Flash Rom

2.Flash CM9-Patch-For-P769.zip

3.Reboot into recovery and flash Lelus touchscreen fix

If coming from stock make sure to wipe data
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
I have to be doing something wrong. Still gets me stuck on the same LG logo. If it helps, this DOES fix CWM v6.0.4.5 so that it's no longer inverted and mirrored.

Going to try reflashing the ROM again, and flashing this before initially booting the ROM.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
I made a mistake on my first upload, I uploaded a jellybean boot.img. My bad. I updated my post with the correct boot.img.

Another thing, I had to manually install "Android Platform Sooner Single ADB Interface" (with device manger) to get adb working.

If you are still having problems maybe you forgot to wipe data.
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
Trying again. I have tried at least a half dozen sites, and I can't seem the get the proper Android Platform Sooner Single ADB Interface driver to install. I tried removing the address from the registry, from this post;

http://xdaforums.com/showthread.php?t=1572315

And that didn't work. It still refuses to let me update the driver to the proper one, saying it can't find any compatible drivers.

I swear, I am less of a noob at this than I sound. This phone is just a gremlin.

Edit: Okay, now the phone will at least boot. It doesn't seem to be mirrored anymore, but as you said, when the phone goes to sleep, it has to be manually powered back off. Also, the touch points are still wonky.

Edit 2: Right, I figured out how to install the proper driver now, and it seems to have worked. So, this time I am going to start from scratch, skip the step of flashing the fix, and see if I can just throw the commands through ADB now that I have Windows 7 actually recognizing my device.

Fingers crossed.
[LG Optimus L9 P760, P765, P768, P769] :
Did you think about odex files? ;)
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
Alright, without flashing the fix posted and just using the ADB commands to push the v6.bin to the proper location, it fixes the mirrored/inverted screen, but as soon as I put it to sleep and come back out, it's reversed again.

Getting closer. Going to flash the fix now and see what happens.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The touch is wonky because you flashed the euro boot.img, Lelus made a flashable zip that will correct the touch screen through the recovery. You don't have to do it the old school way (via adb).

1. flash the p769 fix

2. Reboot into recovery

3. flash Lelus touchscreen fix

4. Reboot
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
This is maddening.

Okay, here is what I am doing, start-to-finish. I boot into CWM, perform all three wipes, flash the ROM, flash Gapps, then flash the fix you posted.

I just got the cwm_ts_fix_p769.zip, so I am flashing that instead of the fix you posted, and trying the ADB commands after if it doesn't work.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The only reason why it comes up normal (screen not inverted), it because you have the proper u-boot (a p769). Once you turn the screen off then on, the system loads the inverted screen. The v6.bin is not responsible for fixing the screen, only the touchscreen. Note: nothing will fix the touchscreen if you stay on the p760 boot.img.
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
So, your fix replaces the P760 boot.img, right? Flashing both now.

Edit: Alright, flashing both the fix you posted and the cwm_ts_fix_p769.zip, I am able to use CM9 on this phone with a properly-working screen. The only problem is as you described; it won't turn the screen back on when it goes to sleep.

Still, this is leaps and bounds above what we had before. Your hard work is definitely appreciated.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Yes it replaces the P760 boot.img with the P769 (t-mobile V10G).

Flash Rom, flash my fix, reboot recovery, then flash touchscreen fix.

I wouldn't worry about gapps right now. I still have to solve why the screen doesn't come back up. Currently diving through the V10g system.img to see what might fix it.
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
I think this might have broken 4G on my T-Mobile variant. It's showing H next to the signal where it normally shows 4G. When I try to check and fix the mobile network settings, under Network Operator, it comes back with an error.
[LG Optimus L9 P760, P765, P768, P769] master90x:

Tks alot. I'm going to try it now :D
[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
Found another potential issue. Gapps refuses to install on this ROM for some reason. I flashed back to your ROM, kuma82, and am going to attempt to flash back and see if that works.
[LG Optimus L9 P760, P765, P768, P769] Ilxaot:
We flash V10A first, correct?
[LG Optimus L9 P760, P765, P768, P769] Polloos:
Gapps work fine. It may be the update-binary, try using a binary of the P769.

No, you can flash this ROM on ICS or JB :)

It works, but, when the phone goes to sleep, you have to power it completely off and reboot it to get the screen to come back on.

Flashed to P769 locked bootloader. It works, but I'm having difficulties fixing the touchscreen. Haven't done this in a while.. xD

EDIT: Fixed touchscreen, but I appear to be soft bricked. Stuck at LG Logo. Yes I can get into CWM.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Thank you too :D

I'm currently trying to figure out why the screen doesn't come back on. The phone still reads the touches but can't see anything. I thought if I ported the hwcomposer.omap4.so from v10g it might fix the problem, but that didn't work. Phone wouldn't finish booting. I hope it doesn't have to do with the "init" file inside the boot.tar.
[LG Optimus L9 P760, P765, P768, P769] Ilxaot:

So this hopefully won't end up with me giving myself a security error, right? :p
[LG Optimus L9 P760, P765, P768, P769] kuma82:
No you shouldn't, the only possible reason might be because the boot.img is corrupt. I'll make a better patch later that checks the sha1, but I'm being lazy right now, lol. It's party time!!

A couple of bugs to report:

Sometimes, the phone does not detect any touches. I have to touch the same icon or spot repeatedly before it picks up. Same with the back buttons and menu button.

Issues with the status bar completely disappearing. Although, that might be the theme I am trying to apply.

I will keep testing this as much as I can, and report back anything I find.
[LG Optimus L9 P760, P765, P768, P769] Polloos:
I dont have this problem, touch work fine.

Status bar have a bug, the icons are not displayed until a notification arrives. Its caused for center clock, in the next update this bug is solved.

Do not delete it because I wanted to completely remove in settings and app or add OTA updates.

OTA upadate its possible in next update, but not sure

Speakerphone does not seem to work.

Flashing the camera fix completely breaks the camera.

Sometimes when I run Root Cleaner, I wind up getting the kernel panic message.

Other than that, everything is working great so far.

Is there a way to get the camera to work again without reflashing everything?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Don't have one to test, sorry.

The speaker phone is buggy I agree, but I believe it's a CM9 bug. Not sure if it can be fixed.

You can try and extract the apk and libs (not sure about the libs) from the CM9 zip.
