Just got my t-mobile l9 yesterday and WOW...so much bloat. First things first, root and remove that crud. Thanks so much for this guide. I am downloading everything and plan to get this done tonight, but I have a question. I'm sorry if this has been answered, but the forum search isn't working and using google to search xda didn't come up with anything either. In step 2 in the first post, is there another place to download the JB .zip file that contains rootlelus and rootflash? I ask because my antivirus recognizes lgp920.dll as infected by a trojan and I can't seem to find any verification that it is, in fact, safe. Thanks XDA and thanks cmahendra!

Simple Way

LMAO. I have been trying to root my P769 20f for awhile now. Went thru several different methods all of which failed midway. found a simple YouTube link that works though. Now all of that bloatware (Scout, FB, T-moile TV) is gone. Try searching for "how to root an lg optimus l9 without computer". 2 minnute video.

general info

hi guys,

i just wanted to share some info that may help someone in the similar condition.

i was on P769 T-mobile USA, 10G (rooted by lelus old method)

I wanted to update to JB from ics. part of the reason was the annoying reminder that ota was available but it never worked as probably must have deleted some crapware, or the fact that i used link2sd which i heard screws with the build.prop that stops the OTA. either way i tooks a V20 JB ROM from here https://mega.co.nz/#!zMtijS4C!FUQuC01hnmKc72cyNMuCvD4A1HIeX3MYyZPZSh3t4aI

and a bin file from this page http://xdaforums.com/showthread.php?t=2173465&page=51 by mrmathematica.

i flashed the kdz with no major problems. after the reboot i found that i no longer had root and the voodoorootkeeper didnt help either.

lucky for me i found the other thread http://xdaforums.com/showthread.php?p=42951767 and installed the LGPwn.apk.

this method worked flawlessly and i regained root. i opened link2sd and recreated mount scripts and everything back to before wirh fully working V20f firmware 99% of apps working and the apps that i found not working were fixed by reinstalling by titanium backup.

now everything is perfect! however i do like the system font that was used by 10G firmware. im going to google it now and see if i can change it.

best of luck.

Help !! Still waiting for your answer/solution

Yes it worked perfect previously, but later on when i factory reset it again and tried to install BusyBox i got a message saying "The su binary was not found on your phone. This application will not work without root". What should i do now? Plz help.

My concern is-

1. Titanium Backup is also not working :( it says: "Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted, and try again. This attempt was made using the /system/xbin/su command."

2. Busy Box not working :(

3. Root Checker Basic says: "Sorry! This device does not have proper root access." :(

However CWM Recovery is working fine. :)

PS whenever i factory reset the device and start SuperSU it says "The SU binary needs to be updated. Continue?" and when i tap continue it says "If u have custom recovery like TWRP or CWM that can be used to (try to) install the SU binary. This is recommended for HTC devices. How would you like to install the SU binary ? " with an options: Normal and TWRP/CWM. At that point of time when i tap "Normal" it says: "Installation Failed ! " on the other hand when i tap TWRP/CWM - the device just reboots and nothing happens. But i never face even single of these problems previously after factory reset.
[LG Optimus L9 P760, P765, P768, P769] Helgen:
Can't get it to work.

No matter what I do, the root never works. I followed all the steps, it updates, installs, but never has su installed and is not rooted.

I have all the drivers installed from the original software from LG on all phone modes. I moved the bin file at 8% too.

When I did the mode where you power off then power on with volume up held, it goes to recovery and it installed the drivers, but the LG software couldn't detect the phone during the update process no matter what I did and with the drivers installed, but when I turned it back on to normal, it detected it. Do I need to install it during the recovery mode no matter what?

Edit: So I tried again while in S/W Upgrade mode (Power up and connect USB) it says "The USB cable and your cellphone are not connected." Why?!

Always at 15% it does this. I have all the drivers installed just like in the post...

Is 20f the last update for 769 tmobile? I'm on 20d rooted now keep getting annoying update notification. There are still plenty of letters remaining from F to Z. If LG keeps releasing updates i'll have to root this phone every week/month until i throw it in the ocean. Something prevents getting OTA update. Maybe its rootkeep i don't know. Last time had to get clean KDZ then root again. Pain in the ass to reload KDZ then root to get rid of update message. Is 20f or later/newer KDZ available yet?

P760 bootloader was unlockable in the very first rom v10a, not the following ones. Then again in v20a and its successors. But maybe this feature had again been removed from a certain rom version on. I unlocked and rooted v20b successfully, updated to v20o thru a nandroid backup from the forum.

At least the unlock is irrevocable, as it triggers an efuse like Samsungs infamous Knox Counter, voiding warranty.

@ALL

PROBABLE MISTAKES

Actually while suggesting following two, I am assuming that you do know many things and done them properly before.

1) Many are not checking the ADB mode is working or not. THE CHECKLIST IS VERY IMPORTANT. When you run ADB command to check devices with "stuff/adb devices" the device line should be seen. If device is not shown, the script will not work. The script will run without any problem if checklist is successful. Don't ignore this.

2) The second common problem is you may not be able to replace the file in LG folder in quick time. You have to be very quick, so the FOLDER should be open in advance. You can even open the folder in the beginning and minimize until it is required to replace. If you are late, the LG TOOL will flash original file and root will fail. Or you can open the folder immediately when it starts at 4% and keep looking for file to replace. As soon as you see 7th BIN file PASTE it with 6th BIN, you already COPY'ed before.

PS: My son is reading this, and literally he is laughing, saying, "Dad, you are teaching to kids or what?" Please dont mind him, he is just too young android kid. I say sorry on behalf of him. I am noob, and you are noob, dont get angry on him. :D And yes he flashed O2X quiet a few times before and L9 too. :D He is 15.

STEP-BY-STEP NOOB'S GUIDE TO ROOT AND FLASH L9 WITH LELUS METHOD

(NOTE: This thread is only for NOOBS like me and for Junior Members.)

IF YOU CANT DO IT, DONT BLAME ME. WARNING: USE INFORMATION AND FILES AT YOUR OWN RISK. DONT EVEN MENTION ME IF YOUR PHONE IS BRICKED. :laugh: YOU WERE WARNED IN BOLD RED LETTERS ALREADY. OFFLINE KDZ FLASHING DOES NOT LOOSE PHONE DATA, BUT YOU MUST BACKUP IN ANY CASE.
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
NOOB'S TUTORIAL TO MAKE YOUR OWN HEX-EDITED BIN FILE EASY WAY

===========================================

1) Download and save on pc your required matching KDZ file found here in this post. You also need a Good HEX File Editor like this one I use. Download and Install.

2) I have already made a small TOOL to extract the KDZ file and get BIN chunks in this post (KDZ EXTRACTION TOOL) with this, you will get "LGP765_AP[6].bin" file ready for editing and use in RootFlashing later.

3) Download LELUS_COPY_OF_BIN.zip (1kb) and unzip it, and you will get "LELUS_COPY_OF_BIN.BIN" (1kb) file. Open it in HEX Editor, select all and "COPY" the content in clipboard to paste later.

4) Now in same HEX Editor, open "LGP765_AP[6].bin" and search for "# hdcp.sh" and your cursor will stop on this string after successful search. If not found in this file then search in "LGP765_AP[5].bin" file.

5) Click on first hash character # and "PASTE" the content you copied from previous file.

6) Now compare your new content as per this attached image file, if extra characters are found below, erase them carefully and SAVE the file. You'r done! Isn't it simple.

You have just EDITED A HEX FILE required for ROOTING L9.

Possible BB and/or RIL issue?

Sorry late reply, as very late I saw your post.

You have two workarounds.

1) Your APN setting must be wrong, Automatic APN setting may not be taking correct APN values. Try manual entries as mentioned by Mobile Service Operators.

2) Install CWM and clear DALVIK CACHE and WIPE CACHE PARTITION. (not data). Reboot and check, if this does not help, that means the BASEBAND and RIL (Radio Interface Layer) from this KDZ, are not matching for your region or mobile operator. Try other previous KDZs but from your own or nearby region.

Very soon Artas182x is going to add only BASEBAND flashing in CWM and you can keep any ROM and flash any BASEBAND.

I have also made initiatives to get our devices supported by GETRIL (RIL installer app) and then we will be able to use any ROM, with any BASEBAND and any matching RIL.

For time being you should revert back to your previous rom and wait until some good news comes. :) Good Luck.

Dont worry, KDZ does not damage hardware :D

Just as example about what I said: you get root, happy and so... Google Play offers you to upgrade Superuser application, you do it. Then Superuser offers you to upgrade su binary, you also do it. Then you can update busybox... You happy. But after you reboot phone - it will be with older versions (su, Superuser, busybox). :eek:

Update: and another important thing what i noticed in rooting.sh script. It leaves /system partition mounted as RW (read/write), what definitely not good.
