I can't install that version LG updater thing keeps telling me that theres errors

EDIT: never mind it installed, i replaced the bin aswell. by the looks of it the LG logo it installed but new problem.

The phone is bootlooping, it stops at fastboot saying Secure booting unsuccesfull!

Cause:

and thats it..

EDIT2: flashed without the Bin and it boots properly. So lelus you said to try it with 20H?
[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
Well i tried the command again on the link you gave me, it didn't work..also the LG logo isn't inverted on this one.

Can someone please tell me hw to go back to stock and get the touchscreen working properly again?

shttps not working!?

Hope this is the right place..

anyways,.. maybe someone can help.

I tried rooting following the op of this thread, i get all the way to where i start shttps, i click update in the lg tool but it says the lg upgrade servers are temp unavailable.. I'm guessing my computer might use a different hosts file (but there was a host file there?!?)

any ideas?

Thanks for any replies :)

edit:btw, I'm on windows7 64-bit and i ran small https with admin, and double checked the host file.

Ok for stock simple run the root bat for ics flash 10g bin add the bin after its done factory reset because it will not boot (volume down + home + power) then install su binary remember touch is messed up add the v6.bin to your sdcard enable usb debugging open cmd from your computer and plug in usb then run the command "(hold up looking for them)" then acept the superuser permision on phone then "(looking for them)" open another cmd because it is a never ending cmd prompt and type "(looking)" and also to finalize "reboot" and the screen is fixed now for inverted boot is another thing...

I went back and uninstalled/reinstalled them, but now im having problems with B2CApp, it shows the "LGmobile phone software update tool install"

Ok, after months of debating I'm ready... I think. I'm still running 10g, is that a problem? I just run the ics Lelus instead of jb lelus right? I can't install artas yet, error meesages, probably because I'm stock no unlocked bl, but the apk has been installed. I run with show touch anyway, All files are on my sd card and lg software/ drivers are installed as per video. There is no cwm touch in the p769 rar file though.. Is that because artas recovery takes care of it? Please respond before I brick my only device, today is gonna be fun. Brb time for lunch and some whiskey.

At least its better than my old Samsung dart :(

Yes, current guide is needed

If it helps, I'd love to see a current up-to-date guide, with clear steps laid out. I'm in the market for a decent/budget android phone for my daughter, and after much searching, the Optimus L9 (P769) seems to fit the bill NICELY. Decent enough hardware, great price.

But I want to remove all the BLOAT from the phone, and I understand from forums that it comes with a LOT.

I'm not new to rooting and unlocking phones, but my experiences have centered around samsung devices, and in all cases, it's been pretty easy.

To be honest, the various forum posts I'm seeing about the L9 (P769) scare the heck out of me, given everyone's experiences with bricking, backward screens, and so on. There are what appear to be some decent instructions out there, but the validity of what's there seems in question, based on which firmware version I start with, and so on. I have yet to find a CURRENT guide that reflects the latest versions of the phone. I've found guides that indicate success, but detail in those guides is a little thin.

I'd be happy to actually buy the phone and use the guide, and post my results :)

In any case, my two cents to add, YES, a really well-written guide is needed here. Thank you, I hope my vote helps?

IF there's a current guide out there that works (assume I go buy the phone tomorrow), post the url?

thanks everyone!
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
Check my post #300 on page 30 on this thread see if that's what you need.

As for Brick so far this phone is pretty much safe only soft brick and all you do is Flash factory KDZ and you're back in business.

As for the inverted screen and logo is not a hickup it actually has to happen having the logo inverted is a signal that you flashed correctly and since the ROM used to unlock is for the p760 that's why the screen get's inverted, but again that is part of the process which will be fixed by the time you're done with everything.

Good luck and if you need help you know where to find us ;)
[LG Optimus L9 P760, P765, P768, P769] caseybea:
OK, I checked out that post, and I have some questions (which is why I'm looking for a more detailed guide).....

>>3.Factory Reset. <--- Double check Make sure USB Debug is ON and Show touches ON and USB connection is in Lg software mode

So this means, a true factory reset done from the phone itself? Or is there an ADB command we're supposed to use?

>>4.Flash 10GKDZ offline mode . <---- do not replace bin for root you will do this later

With what tool should I use to do the flash? Odin, or...?

>>6.Flash Euro open 20B ( This is what I DID in this step, i cheated a little and ONLY replaced the AP[11] meaning before flashing 20B I DID NOT run the Root L9 and after the flash DID NOT flash radio or root.

Where to get Euro open 20b? What does the rest of this line mean? The directions here seem a bit compresed and confusing, sorry......

>>7.Waited 1 hr give or take No signal but sim was in, ran a CMD Prompt as admin and issued the "adb reboot oem-unlock" WORKED!!!

...and during that hour, what was on the phone's screen??? Anything??

--------------

etc....... this is kind of why I'm asking for an improved guide. Much of the stuff in that post, and others, assumes a bit of familiarity with LG phones.

HERE you will find out about the offline kdz flashing. The programs used are given in the thread

And HERE are the official kdz files released by samsung. Just remember to read the thread i gave you 1 carefully

in the 1 hour waiting time you must let the screen always on in the screen settings, with phone connected to internet and usb plugged in with debug on.

When you connect the phone to pc, it will ask the mode that it connect. Here you must choose lg software mode
[LG Optimus L9 P760, P765, P768, P769] Calbino:
Greetings,

I am on day 5 of working to unlock the bootloader, and am having no luck getting past "adb reboot oem-unlock".

I have followed a few different instructions in this thread and others, but one thing I've noticed is that after flashing from stock v10g to v20b, applying Lelus root during flash, I do not have a cell signal. I realise this is probably because it is looking for european carriers, so I've instead left the wifi on for an hour to replace the signal, but this has not worked.

The sim card is in the phone but unactivated, my current T-Mobile sim is too large to fit, and I've been waiting to get this bootloader unlocked before activating the new sim.

My question is, is there something I am doing wrong with the signal? I'm not sure if getting this sim activated first would do the trick or not but I really seem to be missing something.
[LG Optimus L9 P760, P765, P768, P769] Meda808:
When i got my phone in the mail, i took my old tmobile sim and cut it with scissors to the size of the smaller one and it works fine.

This was my first LG smartphone coming from Samsung which im sure a lot of people are noticing how much easier samsung is to work with. I used Carlos's original typed instructions and everything worked fine. One thing i found for my own situation was that using Fastboot was not needed for me as i was able to install root, busybox, and Artas CWM via the mirrored touch screen. it was kind of a pain in the ass, but patience prevailed. There are a handful of threads that are buried now that still contain valuable info such as one in the help section called Mirrored Screen Issues or something of that nature. All the information is here we just need it collected and formatted properly. love you guys.
[LG Optimus L9 P760, P765, P768, P769] Calbino:
Thank you Meda808. I flashed Artas CWM last night and used recovery to flash updated radio drivers. After installing CWM, the mirrored LG boot logo was fixed, and was able to receive a signal through the unactivated sim card. Unfortunately, still just reboots after adb reboot oem-unlock. I only gave it about 40 minutes with signal before trying, I will try an hour now.
[LG Optimus L9 P760, P765, P768, P769] snowlin:
Following your directions now, im in the hour wait step so wish me luck :x

one question though, at the end of everything you mention to flash the 20f u boot to fix the inverted logo - how do i flash only the u boot? or would offline flashing the official 20f work fine?

so basically if cm10.1 is my goal, then it goes:

20f > 10g > 20b > unlock > 20f > [cm10.1]? correct?
[LG Optimus L9 P760, P765, P768, P769] Lelus:
no need to flash 20f kdz after unlocking

cwm/twrp flashable 20f uboot - you can flash it before or after cm10.1

You wont need to unlock the bootloader if all you want to do is remove bloat. rooting is fine.

Ah! OK, thanks for the clarification. Are the guide(s) current for rooting only?

I am kind of on the fence though, yes, primary goal is unbloating, but at the same time, I kind of want the ability to pop CM10+ on there or whatever in the future if I need. Hard to decide.

Has anyone been able to unlock the bootloader after installing cwm and flashing the radio?

I've reflashed 10g to 20B several times and tried waiting 1hr,2,6, a day, and still nothing. I wonder if it has anything to do with installing cwm and flashing the radio fix.

I searched through this thread concerning a question I have, but I couldn't seem to find an answer. I was following along to carlos' video (thank you very much by the way) and I've made it up to where the screen is inverted and I'm about to use the LG recovery tool. Upon first time I checked the apps, the LG Recovery app was missing. I searched through the files carlos had provided and found the apk for an LG recovery app and installed that on my phone. However, after I select (the options within the app) Install Recovery -> stable -> Yes, a message pops up that says "Oops! Something went wrong :( error running exec(). Command " . I'm guessing my problem is stemming from the fact that I installed the recovery app. Are there any tips that anyone has that could help me out?

Okee doke, I realized I missed the rooting part. I rooted the phone, and I was able to flash the radio fix, screen fix, and Cyanogenmod 10.1 (from antonx). Before flashing Cyanogenmod and the screenfix, the radio worked (my friend called me, ha) wifi worked, everything worked as it should. However (after flashing the screenfix and Cyanogenmod), the boot animation for Cyanogenmod is infinite; I believe this is because the gapps I flashed said "4.2.2" when it installed. I'm trying to find a gapps 4.1.2 apk from the google machine. Once I find one I'll flash that and see if it boots past the animation. Thanks for the help!

If we take the easy way out we will never learn........

Need more info here.... give the correct info, what order did you flash? I notice you say you flashed screen fix , then cm 10, did you reset phone? did you flash in this order?

1.Rom

2.Gapps

3.screen fix

4.whatever other flash file...?

boot.... if stuck hard reset then boot again!

I would also wipe dalvik and cache since you did flash the wrong Gapps first....... try the order i gave you and if you get the boot loop just hard reset , let us know!

The first boot takes the longest, try to download the rom again, maybe it's corrupted.
