Unfortunately "Android MTP Driver"'s link doesn't work.4) Install Drivers "LG USB Driver (Download 3.8.1 here)" (Ver 3.7.2 here). Optional Android MTP Driver.
I have an LG optimus L9 (P765). I was trying to load lollipop into my phone, however landed into a Bricked Phone
Here are the thing I did:
Unlocked bootloader using ADB files.
- Enabled USB Debugging
- Installed all the required drvers.
- Connectedmy phone to PC via USB cable.
- From ADB folder I ran command :
adb reboot oem-unlock.
- Then installed Clockmorkmod (CWM) Recovery by command :
fastboot flash recovery recovery-clockwork-22.214.171.124-p760.img
Enabled USB Debugging
Installed all the required drivers.
Connected my phone to PC via USB cable.
From ADB folder I ran command
adb reboot oem-unlock.
Then installed Clockworkmod (CWM) Recovery by command
fastboot flash recovery recovery-clockwork-126.96.36.199-p760.img
Booted into Clockmorkmod (CWM) Recovery.
- Wiped cache partition
- Wiped Dalvik cache
- Tried to install artas182x_p765-ota-eng-artur.zip from external SD_Card. Gave (status 7) error as below
- Booted to CWM recovery and flashed TWRP "instal from zip" [twrp230714.zip]
- Booted into twrp Recovery sucessfully.
- Booted into twrp Recovery sucessfully.
- Cleared System, data and cache.
- flashed cm-11-20141012-UNOFFICIAL-p765.zip from CyanogenMod [ KitKat 4.4.4 ]
- cleared Dalvik cache.
- Restared phone and sucessfully booted. Androd 4.4.4 was working on my phone.
- Then I enabled USB debugging and nstall from unknown source.
- Booted into twrp recovery mode again.
Now it was time to flash Lollipop into my phone.
I followed instruction as stated by artas
- Installed artas182x_p760-ota-eng.artur.zip
- Installed gapps [gapps-lp-20141109-signed.zip]
- Installed SuperSU [UPDATE-SuperSU-v2.40.zip].
- Rebooted phone.
After LG logo screen, there lollipop boot animation.
I left the device for around 30 mins still lollipop boot animation did not end.
Removed battery and restarted. Still the same lollipop boot animation.
Now here is crap I did
I tried to boot into recovery mode, but was unable to do so using ADB files.
Tried several physical combination to boot into recovery with no sucess.
At last I tried hard resetting with Power+Vol Dwn + Home Button, this did factory reset.
Now my phone hangs up showing LG logo.
When I try to connect to PC, no devices are shown.
ADB files also were unable to detect device.
Re-installed LG drivers, still device was not detected.
Tried fastboot option, still no luck
Tried FLASH L9 Factory ICS/JB ROM WITH OFFLINE FIX + UNBRICK as guided by cmahendra, still no luck
Again the same error [Port(or Device) Not Found!]
Please suggest how to make my devices detectable and boot in recovery mode. plzzzzzzzzzzzz
Unfortunately "Android MTP Driver"'s link doesn't work.
I've of course thanked your answer. :good:You can ignore Android MTP Driver as new LG Android USB Driver includes everything the LG Phone needs to connect pc.
Just now have updated the link with new version of LG Android USB Driver version 4.0.4 in my Dev-host space. :good: So the link will never expire now
My LG 9 LGMS769 phone has stopped working again. Can't hard reset, and get dead android with red triangle and exclamation point sometimes. I've never rooted my phone, but in the past six months I've had many issues with it, constant errors that program and software stops working suddenly. I was writing a tweet and the phone crashed and wouldn't start up.
In the past, I've used the LG Mobile Tool to recover it, but this time, at 50% of the upgrade, I get the error "upgrade stopped due to error." This happens at 50% every single time I try.
I am not tech savvy at all, but have managed to use the LG Mobile Tool in the past. Thanks for letting me know about it.
I would love to be able to resolve this issue, and not have to spend money on a new phone.
Thanks in advance!

my phone was already on S/W Upgrade Mode. I already try the official LG Tool but still no luck. Stuck also in 50% while upgrading process. Maybe the problem is on my phone? What do you think? Please help me guys. Thankyou.
Btw, when I first softbrick my phone (lg logo with security error on the screen), I used Official LG Tool and it back to normal and then after a week, that security error came again. I used it again the lg tool and its back to normal again but suddenly, when I restarted my phone the white screen came up with encrypting process and after that theres an "erase everything" button. I spam click it but nothing happens. I restart it several times and tried to hard reset it but when I opened it, im stuck on logo screen. So I tried again the official lg tool and still no luck. stucked on 50% .
Even this tutorial by cmahendra, im stucked also on 50%
Any ideas? Ty
Use this unofficial tool it will solve your problem ( see instructions in guide )
Thanks to all developers and contributors: Bin4ry , adixtra , unknown_world. I thank to all the users of this thread who gave feedback and reported issues time to time, which helped "us" to make this guide better and perfect.I see almost everyone in L9 forum is giving reference link to this flashing guide in their threads, but almost no one is mentioning any credit to this. They are just putting links. What do you all think, pals? Do I deserve a credit or not
Please note the opened file name is only "hosts" and does not have file-extension like txt or anything.C:\Windows\System32\drivers\etc\hosts
Now SAVE file and Close it.127.0.0.1 csmg.lgmobile.com
7) Execute "UpTestEX_mod2_marwin.exe" with "Run As Administrator" option and in Windows Compatibility Mode with "WindowsXP SP3" (must for Win7/8) >> and Select your KDZ file. Select "3GQCT" in Type of Flash and select "EMERGENCY" for PhoneMode. Ignore all other options and press "NORMAL WEB UPGRADE TEST" at bottom. This button is very light and hard to see at first attempt.Post-JB issue: If you have installed JellyBean before, Phone may not go in "Software Upgrade Mode" or Flashing stops at 14% in 11th step.
Then do this WORKAROUND: Keep the Phone POWERED ON with USB connected and on "LG Software" mode and do next step of flashing KDZ with Update tool and the phone will automatically go in software upgrade mode.
FLASHING ERROR AT THIS POINT? If you have installed JB before then your flashing may stop at 4% to 14%. This may be due JB rom already installed before or due to driver not completely installed for "SW Upgrade Mode".
WORKAROUND: Cancel flashing by exiting LG Update Tool. Phone should be still in SW Upgrade Mode, Remove USB Cable, wait 10 seconds, Insert USB cable again and let all drivers install for this mode. The device manager should look LIKE THIS SCREENSHOT. START AGAIN FROM STEP 6 (Read about Post-JB Issue)
Rooting ICS ON LG OPTIMUS L9 (OLD BIN4RY METHOD) Only for ICS.Before we start please remember, Use information at your own risk.
great work, but i do this tutorial for root in my LG p765 from indonesia and its not work. The phone wont restart after i click restore.
My phone has already had 10c when i was buying it. Or i must install 10c kdz from the link you gave it?
ok one thing that was missing after all the hassle was the automatic offline procedure which you must run with command prompt after setting the hosts up and turing on the server as well you must start the windows enabler as a administrator attached is the missing file just rename it without the .txt to use it in command prompt
