[LG Optimus L9 P760, P765, P768, P769] kuma82:
Another successful bootloader unlocked ;) This time it was the MetroPCS version LGMS769. I waited about an hour this time.

While flashing, I replaced/swapped the 11th bin & and the radio (LGP760_CP.fls). I used a LGP769_CP.fls and renamed it to LGP760_CP.fls. I waited about 45 minutes on just signal, took one call, played with the touch screen, & turned on WiFi for about 10 minutes (and then turned wifi back off). Hopefully the logcats and the partition dumps I took before and after will prove useful.

Oh and the u-boot was not replaced while flashing (lg logo was not inverted), so I dd the 20B u-boot (inverted lg logo) before issuing the unlock command.
[LG Optimus L9 P760, P765, P768, P769] jgc86:
I waited about 45 mins to issue the unlock command. I did update the radio before I started and I did leave the wifi on. Got it unlocked the first try no problem. Fixing the touchscreen is a ***** though. That is the HARDEST part. I'm re-rooting 10 g right now so I can fix my touch screen.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
do you by any change have a link to the LGP769_CP.fls? I think i might be able to unlock it tonight using what you said. Do you think it will work if i use the offline updater method instead of fastboot?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Once I unlocked I flashed (with the official fastboot) cwmrec.img. once inside (cwm) I flashed the x, u (for 20f) & lelus touch screen with a flashable zip I made. Then went straight into c.m. you can pretty much leave the offline flash in the dust. If you want I'll upload my zip file.
[LG Optimus L9 P760, P765, P768, P769] nevkuril:
I don't think you really need to flash any KDZ after you've unlocked. I didn't. Because you already have a working recovery, you can flash u-boot from 20f (search for it) that fixes the screen, and after that flash any flavor of CM. To fix touchscreen you just push v6.bin, again from recovery.

EDIT: This flashed form recovery fixes the screen right away:

Look at my signature to learn how to extract it from any p769 kdz. The last post on my thread is a easier way to extract it. Just put the kdz in the folder and in a couple of clicks you will have x , u , boot , recovery, system & radio ;)

You swap out the radio at the same time you are rooting with the offline flash method.

Sorry gang but I'm hit the sack, I've been up past 24 hours already.

oh well anyways here is what i was going to give you.

md5 sum for cwmrec.img (by [MENTION=2159458]Lelus[/MENTION])

a19f842c91e86a7a36082968572f3b9d

The zip is flashable and will install 20f u,x, twrp recovery (by [MENTION=2159458]Lelus[/MENTION]) , and [MENTION=2159458]Lelus[/MENTION] touchscreen fix. Its best to go straight into c.m. to replace the boot.img. but you already did I'm sure ;)

Plus the zip will check if the images are corrupted before installing.

Note: Anyone on a locked bootloader, please do not flash my zip or you will get a security error.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
The whole point of swapping out the radio (LGP769_CP.fls) while flashing (R&D test Tool) is so you won't have to turn your device back off to flash the radio with the 2nd init cwm recovery by [MENTION=3519950]artas182x[/MENTION]

You have to rename LGP769_CP.fls to LGP760_CP.fls. You pretty much don't have to worry about rooting, Just wait for the LGP760.fls to pop up in here (C:\ProgramData\LGMOBILEAX\Phone) and select yes to replace. Aftewards wait 30+ minutes (do like I said in my other post) and issue the command with adb

adb reboot oem-unlock

---------- Post added at 02:29 PM ---------- Previous post was at 02:11 PM ----------

I think if anything 20f may have added a nvalue to the efuse that maybe unrecognized by 20b. Can't confirm, just a theory. I will be happy to try using the radio file as everytime I've attempted I've rebooted to install it or phone sat with x in place of signal.

Have you check your build date on your phone. Lelus thinks the news models can't be unlocked.

Oh and when you flash the euro kdz the lg logo should be backwards/inverted, or else it won't work for sure.

[LG Optimus L9 P760, P765, P768, P769] SomeGuyInOz:
Hi again all. So I'm happily running CM10.1.3 on my P769. When I unlocked my bootloader, I did pretty much everything except flashing the uboot from the v20F ROM. All that really means is that when I start my phone, the LG logo/letters are inverted. Also, if I boot into the bootloader everything is also inverted. This didn't bother me before - it kind of looks cool :p But I've decided now that I would like this to look right.

I just wanted to make sure that all I need to do is flash the 20f_u-boot.zip file provided in these forums (using CWM). That will fix my reversed boot logo but will not touch anything else, right?

Is there any way I could accidentally re-lock the bootloader? That would suck! What if I flashed my ROM using the LG tooll right back to stock v20F? Would that re-lock it?

Also, my radio (baseband?) is the from the radio.zip provided in this forum, too, so it's from the v20D ROM. Is there any advantage to upgrading this to the v20F version? Sorry for all the noob questions. I'm trying to learn as much about this stuff as possible, but its pretty tricky with so much info spread out all over the place :eek:
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
1.Yes that's all you need and it will fix it.

2.No once unlocked at least for now on this phone can't re-lock.

3.I personally flashed the newest radio out there for it and it's working fine mostly radios are improvements in signal and what not.

On that note look at mi sig, why not try CM10.2? working great so far. ;)
[LG Optimus L9 P760, P765, P768, P769] SomeGuyInOz:
Ok, thanks again for your info. I'll fix my boot screen in the morning. I will also update my radio/baseband. Did you extract the radio.zip yourself from a KDZ or a NANDroid backup? Can you point me in the direction of how to do that, or maybe even send me a copy of the .zip??

I originally flashed CM10.2 to my device when I first unlocked it. I went back to CM10.1 because I was trying to get tethering through a VPN to work, and I just couldn't get it going on CM10.2. I did manage to do it on CM10.1. Maybe I'll give it another shot on 10.2 though, soon... :D

Flashing this, v 20f kuma zip is a lot safer than the u-boot fix I made. The old one doesn't check the if the image is good before flashing. If the image is bad you will get a security error or your phone won't boot.

Nothing you can't fix with fastboot though. (you can fix it with fastboot.

Look at Carlos video, do you see when he waits for the 11th bin to pop up, and then he swaps it with the modified 11th bin. Well it's pretty much the same thing. Once you see the radio file pop up .fls you replace it.

Now about the dd stuff and 20b u-boot. The 20b u-boot is that inverted/backwards LG logo that you are suppose to see when you phone is turning on, while on the European kdz (V20B). I used root to dd the inverted logo to the system. Look up dd Linux command to learn more.

This what the command looks like

dd if=/storage/external_SD/u.img of=/dev/block/mmcblk0p2

I'm telling the system to replace the current u-boot (the u-boot is located inside /dev/block/mmcblk0p2) with an image I have one my SD card (which is a different u-boot).
[LG Optimus L9 P760, P765, P768, P769] SomeGuyInOz:
So is it ok if I flash this .zip through my current CWM recovery?

I had already applied the touchscreen fix and installed CWM and am running CM10.1 successfully. If I flash this zip, I will now have TWRP instead of CWM and my boot screen will not be inverted any more... correct?

Update: Should I simply delete the V6 stuff from the zip? And if I don't want TWRP, I could delete the twrp img file, too, right? Then just flash my updated zip using CWM?

Update2: Ok, so I can see I would also need to edit the updater-script. If I just wanted to remove Lelus' Touchscreen Fix, could I just remove the lines in RED below, as well as the v6 files and directories from the zip?? And is there any point flashing the x.img file (what does it do?) :confused:

Good luck.

I tried this. Went into fastboot on the phone and issued the fastboot oem-unlock command after making sure the phone was recognized via fastboot devices. It gave some FAILED remote (something) message, I forget the exact message.
