Need to flash back the radio.zip for the P769 for the baseband that's all!

You should have : LGP769AT-00-V20d-TMO-US-MAR-16-2013 or at least that's the one i have after flashing the radio back.

I will copy my post fix it, make my own uploads and link them then post as a tut, but i did use the video i think they complement each other it's just a few things here and there but the vid is great for noobs like me! lol, as it shows the process for offline flashing of KDZ's and the installations and the running of the programs and commands i would even make one but i'm too picky and i would want it to look really good and be able to add a second stream for the phone ect, any open source/free programs anyone could recommend?? for capturing from desktop and something for editing...

---------- Post added at 06:08 AM ---------- Previous post was at 06:05 AM ----------

Now you post them!!!! lol :p had to use the nand mgr to install twrp! :p

But seriously thanks a lot i'll mirror once i have them up on mega.

By the way any themes for TWRP that would be compatible with our phone....felling tempted to do a few but the tuts and resources are old..

---------- Post added at 06:36 AM ---------- Previous post was at 06:08 AM ----------

Just to make sure, are you running as admin? did you make sure you put compat to XP-SP3?

if it happens just close the program and do it again and just to make sure, at what point does it do it? what are you flashing when it happens? and last but not least this is where the vid is confusing

If you use offline KDZ flashing if you go from 20f usa > 20b open euro SELEC DIAG on the top Right.

But if you're going to flash after 20b.KDZ open to downgrade to 10g.KDZ T-MO, USE EMERGENCY from there on.

In other words

ONLY SELECT "DIAG" IF FLASHING FROM 20f T-MO TO 20b OPEN EURO AS YOU ARE FLASHING FROM JB TO JB

For flashing from 20f TMo JB > 10g TMo GB and from 10g TMo GB > 20b open euro JB SELECT "EMERGENGY"

hope it makes sense and helps you out.

Lol, you're welcome.

To tell you the truth I really didn't know what that theme thing was, Lol. I just like it more then cwm. It was kind of hard saying bye to an old friend, cwm has been there from the beginning.

I had used cwm... but then on htc discovered 4ext touch recovery OMG!! love it you can even change themes but they don't have it for our phone looked up TWRP and they also have a few resources for making themes but they are old. i do want to try and port one of the 4ext themes that i use on the htc, so let's see if i get a chance to do it

Any suggestions as for the good opensource or free software capturing the desktop and for making and editing the vid??

ps: any chance you can make all 3 recoveries flash-able? so when I make my post of how to unlock i can provide a link with all 6 of them, the 3.img for fastboot and the 3.zip flash-able for cwm.

I just want to make sure when I do the post I have all the resources available from the OP and don't have to send no one hunting i will reference the different original threads of the info and give credit to all the people who have contributed tho our phone, like carloswii5 for the vid and recov .img, Lelus for the L9 recov installer you for the flash-able .zips and so on...just want to make it nice,easy and a 1 stop post.

yeap, program is set to win xp sp3 compatibility and running as admin

the thing is, i tried running the program again but it just froze up again [i don't know if starting it up again will even work since my phone is left at the black screen with the "s/w upgrade" text, only way i can free my phone up is by pulling the battery]

i'm doing 20f to 20b, so i left it as diag, as he says to in the video
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
Same thing happen to me that's why i told you just close the program and start again... the phone should stay on the S/W screen you only start up the program again.

but if i was you as it did happen to me same as you're doing i would follow my post of what i did and worked for me starting from loading the x and u flashing.

Factory reset phone (make a backup before if you need it), flash x and u then follow my post as you watch the video for reference on what you should see when doing the steps.

ps: make sure dubug is on, and phone is in lg software mode and after every KDZ flash do factory reset, just a little friendly reminder.

Good luck.

I was able to unlock my phone but flashed back the 20F. I rooted it afterwards, so my phone is rooted and unlocked, but I can't get into fastboot now.

I tried adb reboot oem-unlock and the omap4boot methods, but neither works. The phone just reboots normally. Anyone know of other ways to get into fastboot?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
20F boot.img does not contain that option, you need to be on a custom ROM (like CM) or an official unlockable kdz (like 20B). If you want to use fastboot on 20F, you have to do it the unofficial way.

Use lelus fastboot, you must be doing something wrong if it doesn't work. When you plug the phone into the PC (with the battery out of course) do you hear a sound of a driver connection and disconnecting?

[LG Optimus L9 P760, P765, P768, P769] webdoctors:
ya but the driver keeps connecting and disconnecting, so it can't make a stable connection. I tried to update the driver according to instructions, but it says already installed. I was able to install cwm via the android store, so I guess I've got everything now....

All three links I provided on that thread, will have you running fastboot like a pro. :cool:

Don't dismiss fastboot, this stuff can save your phone.

Note if you have problems about driver no signed, reboot windows and press f8 at boot to disable driver security enforcement.

here is the non touch CWM [MENTION=4056938]elpuertorro[/MENTION], you know this stuff is real easy to make, I just edit and create those flashable zips on my phone. I can tell you how if you want to learn.

[LG Optimus L9 P760, P765, P768, P769] geeshiet:
Try this... But first you need sim card activated and have signal.

1. Connect phone to pc (make sure usb debugging is on), should show android bug legs.

2. Select "LG software" for pc connection , simple way is disconnect phone annd reconnect and select it.

3. Now make sure you have a sim card on and activated (if unlocking process still doesn't work then switch to wifi.) Then wait 30 or more min.

4. After that, move android folder with adb files to "C:\" drive on ur computer. Then open cmd and type "cd c:\Android" enter then type "adb reboot oem-unlock" enter.

5. After it'll show mirrored confirmation of unlock and just press vol up. Then reboot.

Then follow all the other steps after that.
[LG Optimus L9 P760, P765, P768, P769] The Bouncer:

Maybe it's not meant for me to unlock this phone. :( I'm getting a fatal error with the KDZ flash program...Which I have used before with no issues... What in the world... Uninstall/Reinstall everything... Oh joy... I'll keep you all posted... good guide BTW.

EDIT: Got it all working... V20B has been flashed, and connected to WiFi for 1 hour. oem unlock command did not work. Trying it again.

EDIT 2: Yup, went back to Stock/Root. This process is entirely to frustrating... Its pretty easy, IF you know where to touch the screen. I ended up dialing 911 twice in the process. HAHA. Anyways, I've decided I'll keep the phone, but until there is an easier way, my bootloader will just have to stay locked.

Need a little help here. I followed the guide for my p769 and got stuck pushing the "oem unlock" command (I assume it won't boot into fastboot as I don't have cell service in my area). In any case...I decided to forgo unlocking the bootloader and attempted to re-flash the factory V20D image. It flashed...but the touch is still inverted and I can't find a fix for it. Can anyone offer any suggestions on how to completely re-image the device? Any help is greatly appreciated!

EDIT: I should also mention that I am receiving a "battery level is insufficient" error when flashing regardless of the fact that the battery is fully charged. I'm at a loss...

EDIT 2: Despite battery being fully charged, I am unable to flash any KDZ to the device and receive the same insufficient battery error...

EDIT3: Apparently the battery had TOO MUCH of a charge. At 100% it registered as a battery level "(1)" to the LG update tool...allowing it to drain to 90% did the trick. I'm not unlocked...but I've learned alot and have at least rooted and repaired the touch on the device. Hope this helps someone else...

Hmmm give this a try

flash x and u

then flash a KDZ with ICS for your phone> reset

flash 20b open> reset

go to settings> usb debug on and just for the hell of it screen never off

wait 45 mins to be safe send unlock command

if it works then root and what not

if it doesn't if you had wifi and signal this time turn off wifi, if it was off this time turn on, remember starting from beginning... just trying to see what helps you

another thing i'm not 100% sure but also does your lg logo at least look inverted? just asking since your phone is a p768 don't know if it happens to yours for us that's an indication we are doing it right if is not inverted then that says start over lol.

so give another go and see what happens i think if you get stuck on one of those there is some workarounds i know i posted them so look them up if you do get a black screen or it doesn't reboot after a flash then that means hard reset vol- + Home + power then keep on with next step and so on good luck and let me know

Im trying with your advice from HERE, using P769 x and u files, roms, etc.

I get something different this time, my screen was all black after flash x and u with adb and 10g for 769, then rebooted > hard reset > screen still black i couldnt set debug on or lg software mode as i was not seeing anything, so i rebooted on emergency mode (still didnt see a thing, screen black all the time) and flashed 20b europe open.

After this the phone booted up, i saw lg logo (not inverted, but with some issues in the screen, the borders are kind of white) and i set up the phone normally > enabled usb debug > enabled show touches > usb in lg software mode > installed drivers cause it asked again > wifi off but i have signal.

you only need the touch if the screen splits as u press in one place and it registers in another if that's not your case then no need to activate it ;)

ok but if it doesn't work try but this time with a ICS for your phone, so x and u then flash a ICSp768.KDZ for your phone model anf then do the 20b, remenber the touches are only for us wonky inverted screen people.
