Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open

I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

b) Press and hold ‘Home’ key and ‘Volume Down’ key.
c) With these 2 keys pressed, press Power button and hold till phone starts to boot in reset mode.

Thank you a lot of combinations of 3 booton Home, Volume Down, Power solve the problem thank you very much
I would really like to return to Froyo, but... I don't understand what rajko34 did.
Like, the v10 baseband is available but where I can get a stock froyo rom to flash with the LGMDP.exe?
If I flash with KDZ, the baseband is flashed/downgraded too?
Thanks in advance

Hi,
I am replying to this post just want that other should aware about the facts that Downgrading from 2.3.3 (V20) to 2.2.2 (V10) is possible and is successful using KDZ. You just have to take care of some below Points before flashing:
I AM NOT RESPONSIBLE FOR ANYTHING GOES WRONG TO YOUR DEVICE. TRY ON YOUR OWN RISK
1. Always Use latest driver from LG and make sure that your device is disconnected and any previous version of drivers should be uninstalled from "add and remove programs" using Windows XP SP3 system (Including LGE Virtual Modem,etc. etc. ..!!! (The one who already have latest drivers and clean PC won't find "Virtual Modem" in the device manager, So just Chill ) ..Check device manager and uninstall if they still there and also uninstall drivers from other vendors like Nokia, samsung, etc.
2. After uninstalling drivers , restart your system and make sure that your user is an administrator and then install New LG drivers from the LG official website (Just Google== LG P500 drivers ). and Disable LGE Virtual Modem if still its appearing in the device manager.
3. Always make sure that USB Debugging is enabled on the device and your system supports USB 2.0 (High Speed), so notification like "Hi-Speed device is plugged into Non Hi-speed USB" should not appear.!!
3. Extract KDZ_FW_UPD_EN.zip and Install msxml.msi and reboot your system again.!
4. Again you need administrator.!
5. Now Plugged the Device via USB.!, System will install drivers for your device. Wait let the system completes the driver installation .!
6. Unplugged the USB from the phone and Restart the Phone.
7. Wait for the phone to Boot and load completely (Approx 5 minutes).
8. Set Display Brightness timeout to 30 minutes and ensure USB debugging is ON.
9. Plug the device again and keep it at a place where it will not get disturbed. (Also ensure that You have Good working Data Cable, Hope Your Original one is still alive )
10. Open KDZ_FW_UPD.exe, select type "3GQCT" and phonemode "DIAG"
11. Click browse and select "V10E_00.kdz" file from where you have download it, I have used Indian version because I have Indian LG O1. (I recommend V10E_00.kdz because i used it twice and it works lika a charm :victory: )
12. Now the Flashing Part .! :fingers-crossed: ...!!. Click Launch Software Update.!
13. The phone will goes to Emergency Mode (Don't panic).! and the flashing process will start.. ! wait for flashing to complete.! Ensure that your system will not goes on Standby or sleep.! And If you are using a Laptop I suggest you to plug in the power first.!
14. I always make my mouse moving while flashing process is in progress. It make me feel better . So you can also try this
15. The flashing process may take 5-10 minutes to complete. and you phone will restart itself indicating the offline battery charging screen.!
16. Wait until KDZ prompt "FINISHED" in the end of the log.
17. Unplug the USB and wait for 5 seconds and press and hold Home+VolumeUp+Power simultaneously for Hard resetting the phone .
18. When The screen Shows LG Logo leave the buttons and Hard reset will take half a minute to complete.
19. Wait and Let the device Boots ups completely. (First Boot will take 5 minutes to get you to the lock screen)
20. Done.!! Congratulations.! You are now Downgraded to 2.2.2 . :highfive:
Good Luck :good:
IF anything went wrong during the flashing process or KDZ gave you any error in between the process.! Please DONT pull the battery out from the Phone. Else It will HARD BRICK YOUR PHONE.! And u are not even able to get the phone Power on..I mean Dead! Just Find Support on XDA and try and try again.! (Also suggest you to do not unplug the data cable, it may also lead to HARD brick the phone.)
In this situation ensure that you have a right flashing KDZ file. and IF you have the right one use different "phonemode" like Emergency, Emergency_CS, etc and try and try again.!
IF still wont work try to shake your phone and touch the screen again and again and try to launch the software upgrade
If still device is not responding try lgmdp method and try to flash a recovery and Image.
If nothing works restart you system and then again launch the software update in emergency mode.! (This option works for me once but i recommend you to try it as a last choice)
Don't pull the battery out and ask for support on xda.! Might be someone save your phone's life.
If the phone is still stucked you have to get it to the service centre. (If your phone is in warranty they will replace the PCB free of cost)
Hi there,
Some weeks ago, after many months of low space problems, I did a factory reset instead of deleting app by app.
But after that, I started having some problems:
Home button doesn't returns to Home, but it still works for mousing off the screen when it's off
Recory is missing
I give apps root, but they don't turn root.
The home button ... well, I can survive without. The Recovery... I haven't used it since I installed it. But the root is very important, as I want to use many apps but I need root to use them.
So well, let's try another factory reset. But nothing changes. So... let's change the ROM. But hey! I need recovery for that...
I haved tried many times to root or unroot the mobile, but it doesn't works. I have done it using many ways in Windows and Ubuntu, but nothing works.
Do you have any ideas about how can I fix this problems?

Instead of tweaking your device by rooting it or unlocking it.. I suggest you to repair the phone's software by PCC or SEUS!

To install recovery use xparts from playstore!
Or if your bl is unlocked then flash any kernel using fastboot! Every kernel with itself has an inbuilt recovery!

I managed to access recovery. And I installed a ROM, hoping that it could repair easily all my problems, plus upgrading my phone at the same time. I installed this one http://forum.xda-developers.com/showthread.php?t=1880321
I downloaded all the .zips I saw, and thinking that I could merge all them into a single one, I did. I though that this was the way to do it.
I did a backup of the phone, and erased cache, dalvik and did a factory reset. I installed the merged .zip, and after reboot:
The phone boots, the "Sony Ericsson" screen lasts for a few seconds, then I get a black screen for a few seconds, and the "Sony Ericsson" screen appears again, to dissapear, and keeps looping indefinitely.
I have been trying for a while, but I'm unable to boot the Recovery or even the Download mode. Maybe I don't know how? What I do:
Press power until it boots, wait until Sony Ericsson logo appears, start pressing Vol Down again and again <-- This worked for me earlier for accessing recovery before installing the zip
Hold power, home, and Vol Down (When doing this, after each 10 seconds (after the Sony Ericsson logo fades away, the mobile vibrates shortly, like when powering it off)
Hold power, home, and Back
Hold power and back
Hold and Vol up
Have I bricked it? How could I repair this for installed each zip one by one?
Guess that by now, I'll have to search my wristwatch.
To Enter Recovery:
You have to press back key again and again while booting(on Sony logo appears).
To Download mode:
Power off the phone.
Then plug the usb while pressing back key.
To Fastboot mode:
Power off the phone.
Then plug the usb while pressing menu key.
To Install a stock rom:
Download a Stock rom.
Then flash it via Flashtool.
or
Use PC Companion to repair.

This was the solution. I though that it was some ****ty software that wouldn't work properly, but I have to say that it's intuitive, and have repaired my phone without problems.
Thanks a lot. This have returned my phone to the state of after-buy, which is why I did the factory reset that made so much problems. Thanks!
hi guys, I think my P768 is bricked = '(
he was V10A, I installed v20a on it, I installed the root and cwm. then I flashed back V10A accidentally and now the device is stuck in the recovery screen. The lg updater tool does not recognize it in recovery and when I do power + vol up it also does not work (because of jb i think it) ... I also did hard reset several times, it reboots back to recovery screen, and the flash still doesnt working...
I'm desperate, what do I do?
Edit;nevermind what I wrote before.
Turn off your phone, remove the battery, while holding vol+ &power plug usb cable to the computer, you'll see sw mode, put the battery back in ...
Use original LG tool(lg pc suite). Make sure your hosts file is clean
thanks for the help, but i tried and the tool said "problem with communication between cell phone and pc"... i'm sure that all drivers are installed
sorry for my bad english =/
====
well, i did it and at 15% of analisys the tool said "the usb cable and your cellphone are not connected... please connect and press restart" =/ (i used pc suite also, it didn't recognized anything)
=====
after losing a few hours of sleep worked perfectly in the online tool ... I almost cried with emotion lol, thanks for the Force!!
I have exact issue with 15%. How you sorted it out?

Hello.
I recently sold this phone and went to factory reset. no problem. However, i forget i deleted the STOCK home app. THere is no launcher on the device so LG Setup Wizard simply crashes when finished setting it up. There is NO ADB since the setting has been erased. I need to re-enable it in settings but can't get that far since LG Setup Wizard keeps crashing..
I think i'm screwed.. what a stupid way to brick..
Device is: LG Optimus L9 P769 T-Mobile variant. Thanks guys!
you should be able to put your device on download/emergency mode and flash a kdz file with lg tool, you tried it?
if don't try yet, take out your battery, hold + volumen botton and put your battery again holding even + volumen key, and conect your to your computer, it must show the yellow screen with the legend download/emergency mode, and in your computer must be install the drivers, to exit the download/emergency mode just take out the battery or hold the power button, and for flash a kdz file, search a tuto, there are many, and many videos to make it easy . All this process let your device as new, all applications and configurations
I am aware of that mode but when attempting to flash that way before, after upgrading to jellybean, it would never flash for me. So I didn't even try it. I'll give it a shot though. I also was able to download one of the cwm backup zips posted in the other thread and extracted the system partition then created a .img image out of it and will try both your method and flashing that img file when I get home from work. Thank you for your post!

SOLUTION
Installed the ICS uboot.
Booted to SW Upgrade mode via plug USB, hold volume up button, place battery into device
Launched KDZ update tool and it connected and went smoothly!
If you have the JellyBean uboot, it won't connect in SW Upgrade mode if booted manually.
Hi guys! Yesterday I decided to unlock the bootloader, flash recovery (twrp 2.8.6) and the cyanogen 11 nightly. Everything went good until I tried to install the gapps, I noticed that the physical shortcut to enter in recovery (after the turning off, of course) didn't worked: the phone restarted or boot up the rom, but I was able to enter in recovery from the advanced restart menu from the rom. Going into the info of the phone where it says kernel there was written "unknown" and no way to overclock. So I decided to reinstall the kernel (the cyanogen11extended) from twrp, everything went good except that I couldn't restart into recovery, it stuck on rebooting until shutdown. So I tought let's use fastboot to erase ad flash the recovery partition and the kernel, but it didn't do anything even if on the cmd said okey and finished in something about a second, but when i tried to enter in recovery I always get stucked on rebooting. So I tought"well if I have the system image I could flash it with fastboot and restore the stock kernel", so I erased the system partition and tried to flash the system.img and I get the message that it is too big for the destination device. Now I don't have a system installed tye hotkeys don't work and I'm stuck on LG screen logo.
There is a solution or do you suggest to send the device in warranty, instead?
Pull the battery and try to enter download mode.
Hi vagelis! You mean without the battery? The hotkey is vol up+power, right?
Edit: i tried without the battery pressing the vol up + power (also tried with vol down + power) and it doesn't work, on the screen I have an image which says to put the battery in, and holding the keys has as only result to reboot the phone showing the image... I guess there's no hope right?
Edit2: I entered download mode using the g2 method, now I have to downoad the kdz rom and the lg flash tool to unbrick, right? But where I can download it since the lg site for the firmware is apparently down?

Ok guys, I was able to unbrick entering in emergency mode e doing the flash tool stuff. The strange thing is that when I start the flash tool putting the file kdz and going forward in the next window, when I click on read phone info the program stops working, if I click directly on stuff then the lg mobile support tool is opened. Now when it starts to write on the phone, the tool says that an error occurred (something like "the server is offline) but on the phone it says the port com and start to download the rom. If I say ok to the error of the lg mobile support tool it stops the firmware update and stops the program, if I don't click ok the firmware update end is work unbricking the phone.
Now I noticed that with the stock rom from the version v10h until the last one towelroot is not working, so I downloaded the v10g germany version (since the italy version was offline) and flashed with the same procedure as I have done with the unbrick, so I could run towelroot and flash the twrp and the cyanogenmod11. Thank you so much for your time!!
The topic is quite old, but I've just solved that problem. You should just do it:
1) hold power and vol down till you see LG logo -- immediately release these buttons and
2) immediately hold power and vol up button to enter into factory reset menu.
Then click "yes" and next "yes", too.
That's all.
