Took the plunge and also flashed this.

Made a nandroid backup first and then flashed, selected yes to preserve root and phone is now running V20F. I had previously run the disable tmous crap script and this didn't seem to inhibit the flash which is a great thing :p. Even the stock (non-branded LG) boot/shutdown animations were preserved. If anyone wants the stock LG boot I've attached them to this reply. They come off the European L9 variant I believe.

lost recovery

hello. i flashed this, but phone still says v20d. half my apps keep crashing, and i have lost custom recovery. root is still intact, but no recovery, so i can't flash my backup.

should i try to install recovery again following original root/recovery thread?

edit: L9 recovery installer apk DOES work to re install CWM.

I know how to change the boot up animation but how do you change the shut down animation?
[LG Optimus L9 P760, P765, P768, P769] quailallstar:
I placed both the boot and shutdown zip files in the same location as the stock TMOUS files. I did however rename the TMOUS files from .zip to .bak and used the exact same nomaclature to ensure it would work 100%.

Check out the screen shot for a visual of what I'm saying. :good:
[LG Optimus L9 P760, P765, P768, P769] redheadplantguy:
did you unzip the zip, or just rename your new one shutdownanimation.bak

and what is the disable tmo crap script? i have tried flashing, and it doesn't take. half my apps crash, and recovery gets lost.
[LG Optimus L9 P760, P765, P768, P769] quailallstar:
Sorry if I was not clear. The stock tmobile files are also labeled "shutdownanimation.zip" so I just renamed the .zip to .bak and that changes the file type. I did not unzip anything. This way all 4 files are still in the same folder but the phone only reads the LG ones :)

[LG Optimus L9 P760, P765, P768, P769] TheCoutures:
If you can get the original MD5 you can check the download here prior to install using this software

http://www.softpedia.com/get/System/File-Management/MD5-Check.shtml

If not try downloading again and reinstall it could have been a bad download.

Ensure you are downloading from a computer and transferring to your device and not doing so through CWM by mounting the SD card, these are all things that have been know to cause errors in install in the past.

[LG Optimus L9 P760, P765, P768, P769] Kid_Ding:
If you have the ota zip from this thread, then you must be on 20d. From that point, reboot into recovery and INSTALL not restore from int/external SD.

[LG Optimus L9 P760, P765, P768, P769] carloswii5:
Your right it's not rooted but what you could do is make sure you have superuser.zip and then flash it after you have flashed the ota zip
[LG Optimus L9 P760, P765, P768, P769] Kid_Ding:
You're correct, you will need to be rooted. This OTA is a minor update for 20d. If you were on 10g (ICS) you would need/get a full update which would be much larger.

I have flashed this already and can confirm that it works.

I don't doubt it works but I don't want to lose my root. I am on rooted V20D. Since the update is so minor I would happily stay on V20D but this damn nag pop up from Tmobile is killing me.
[LG Optimus L9 P760, P765, P768, P769] Kid_Ding:

Step By Step Instructions

This step by step guide is based on my recent experience yesterday. I assume no responsibility for any damage done to your phone. Try these steps at your own risk (which should be minimal to none(.

Prerequisites: Must have root, must have Clockworkmod (CWM or as it's called on your phone L9 Recovery Installer) installed.

Steps:

1. Download the OTA update for V20F and transfer to external SD card afterwards.

2. Make a full backup using Titanium Backup (free version from Play Store) and for safety download Voodoo OTA Rootkeeper and run that just to be on the safe side and make sure you don't lose your root. This is just a precaution as the update at the beginning of this thread comes with an option to keep the root when you are finished.

3. Using CWM choose the option "Reboot to Recovery"

4. Go to the back up and restore option in CWM and make a back up to your external SD for safety.

5. Go back to the main menu and choose the install zip option and then choose install zip from external SD.

6. Find where you saved the OTA update from the first post in this thread and choose to install that. This will take some time, so don't freak out.

7. After the update is successful then go back and you should automatically get the option to keep the root, choose yes and wait. Again this will take some time and when it is finished your phone should automatically reboot and everything should be the same as before but updated to V20F. There should be no need for backups but at least you have them incase something goes wonky.

8. Profit. :victory:

If anyone here see's that I have missed anything please inform me and I will edit my post. I hope this helps fellow noobs like me. Feel free to copy this and put it in the first post if you feel it will benefit others. Thanks to everyone for their time and patience in helping me.

Excellent job! This worked perfectly. Didnt lose root at all either and am on V20F (still 4.1.2 for those who may see that number and not be so sure after there updates)

2 minor things, after the updated zip in CWM 2 options pop up when you "go back". One has to do with a recovery or something SU related, hit yes to that, then another comes up referencing the possibility of losing root. Hit yes to that one as well.

I wasnt sure if i was correct on those 2 parts as they didnt pop up auto but it worked out all the same.

What is everyones Radio number? Just want to confirm i have the right one (been messing with my phone alot before update)

L6260_MODEM_SIC_01.1305.00 is what i currently have

Well the problem is, we cant directly mod kdz files AFAIK. We could however mod bin files, but we are not able to repack the bin files into a kdz, which we would be able to flash. So either we find a way to flash .bin files, or someone finds a way to hack .kdz files. We could also probably use cheatengine, to manipulate the flashprocess. Look into the Optimus Black forum to find a guide. Then we need a good scripter, who could automate the process and it would be way easier ;) if you need any more info, just pm me :)

CWM recovery for V20F, by Carloswii and Nathan are no longer available. There is one CWM recovery for V20H. Would this work? T-Mobile says V20H is the most current.

Any help would be appreciated. Thanks.
