Installing usb drivers in windows 8 (64bit) and flashing on it is randomly working for some people and not for some. Try uninstalling all LG applications/drivers, restart pc, and start everything from scratch. And when you are stuck at 14% that is exactly the moment when phone is required to be connected to pc via SW Update Mode and due to drivers are not properly installed you get this error. I dont know if this works or not, but while installing dont let windows install WDM (online) microsoft windows update drivers, there is one button in Driver install box saying "SKIP OBTAINING DRIVERS....blah blah" Click on it and LG drivers already installed on PC will be loaded. And then start again from beginning.

Lemme find and image for you....click on that circulled link.

I exactly had this problem and this workaround worked for me.

I dont guarantee this will help. But try this and inform any further issue, so we can take it from there. Good Luck.

Now i see that i've written my post in the wrong thread i meant to put it here http://xdaforums.com/showthread.php?t=2085344 but i was too sleepy in the morning to pay attention.

The main issue is, i think, that i do not have the LG Software option when I connect my phone to the usb cable. The custom ROM that i've installed only has media device and camera. So i think that the drivers that i actually need are never installed because the phone doesen't ask for them. I will try your solution as soon as possible and report back with my results.
[LG Optimus L9 P760, P765, P768, P769] RobbingHood:
I have the exact same problem as b3cks89

Also, I'm on stock JB V20B rooted OTA, so I have the option to choose LG Software mode. All drivers got installed successfully, every step worked, until the flashing itself. Keeps getting stuck @ 15%, device not connected.

I also tried it on a different computer that has NEVER been in Touch with s smartphone, same result. Both are Win7 x64, tried the whole tutorial multiple times, also all availavle fixes.

Seems like my device is cursed, first unlocking BL doesn't work on now this :crying:
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
Your problem seem same as b3cks89 but situation is different. He have custom rom and dont have LG Software mode.

Will you pals please share which Variant you have. Its difficult when full information is not available. Also on which version and region rom you are on?
[LG Optimus L9 P760, P765, P768, P769] vinswong:
Thanks you very much:good::good::good:

works perfect with V20B CIS COUNTRIES

but I have two questions

1. Did this method unlock my bootloader?

2. Is it compatible with Hong Kong version:confused:

thanks
[LG Optimus L9 P760, P765, P768, P769] b3cks89:
I tried all night still no success. I finally give up.But to answer your question, i have Android 4.2.2, baseband LGP760AT-00-v20b-EUR-XXX-MAR-03-2013 - CyanogenMod 10.1 - 20130331 - Mike's Unofficial for LG P760 with Kernel 3.0.21 -KANG+ mikegapinksi@Mikes-Mac-Pro.local #2
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
great. thanks for confirmation, that means I made perfect BIN file. :D

1. No you have not yet unlocked bootloader. Its just a JB update with root.

2. No. Its not compatible with HongKong KDZ file. For that we need to download it, extract it and edit bin file and upload it. This is not possible for me for few days coz dont have good upload speed (128kbits/ps). :(
[LG Optimus L9 P760, P765, P768, P769] vinswong:
Cant understand how to install CWM :(
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
I think there was CWM installation in that thread, but it seems I goofed up. When I reach home (atm in office) I will find the thread.

You can still push CWM recovery if you have unlocked bootloader. Have you tried that from this thread?

EDIT: Also try installing "Rom Manager" and try to install recovery. Install, Run and click "Flash Clockworkmod Recovery" button. (video)

[LG Optimus L9 P760, P765, P768, P769] cmahendra:
unlock with the help of adb mode command (Aremcee's Instructions). Just for unlocking, you dont need fastboot drivers. Only ADB drivers are required to unlock. At least works on P760.

Some P769 users are not able to unlock without fastboot drivers. I dont know why, but they said so.
[LG Optimus L9 P760, P765, P768, P769] dreamnewbie:
AAAh. but what i did not try was deleting files from internal memory... after formatting internal memo, i tried flashing. it crashed with DIAG mode, bot went perfect with EMERGENCY. SOLVED! Now i am happy with JB v20B :)

Thanks for not killing me for my posts :)
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
congrats. in fact my guide shows an image also to use "emergency" mode. always worked perfect.
[LG Optimus L9 P760, P765, P768, P769] dreamnewbie:
True. I just forgot to switch :)

And i have other question. I am using L9 as an internet gate. My sim card does not allow to make phone calls (but ofc i use 3g/hspa to contact net). Is it ok to unlock BL now or do I have to switch to other SIM and wait few minutes?

error

This is embarrassing. After many successful flashes I am not able to do it now.

Here is what I have:

P769BK running 10G

I am attempting to flash P760 20B so that I can flash CM 10.1 as per this thread:

http://xdaforums.com/showthread.php?t=2216542

When I have my hosts file redirecting the 2 lg.com URLs to 127.0.0.01 I receive an error:

"Notice: Scheduled Server Maintenance"

When I don't have my hosts file redirecting I receive the message:

"The Cell phone is the latest version already. So you don't need to update."

I have tried this on 2 computers.

Any ideas?
[LG Optimus L9 P760, P765, P768, P769] kyle7:
Hi all master, im a newbie for rooting l9 and read the instruction on the first post.

but still have some questions.

Mine one is P768, its the Taiwan version. Current version is v10e.

I want to upgrade to v20b which is the hongkong factory rom and root it.

which resources i need to download? for JB or ICS?

What is the step for that? Is that flash the v20b at step 9-10,

or flash v10e back at that step first, then flash v20b rom?

Sorry for so many questions. Thanks a lot!
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
Don't flash p760 or other Roms on p768. Your camera will not work. Plus u may get some more problems a noob cannot solve.

Wait for JB for p768.

[LG Optimus L9 P760, P765, P768, P769] kevev:
Now I am softbricked. :p Any ideas of how I can get out of this pickle(situation)?

---------- Post added at 02:50 PM ---------- Previous post was at 02:08 PM ----------

I got it! Damnit!

cmahendra: I used the latest flash package you posted in this thread and it did not work.

I was using the JB package on my P769BK running 10g.

The one that worked was your previous release ICS package.

I am flashing the P760 20B.

I don't know if anything needs to change in your first post, or if I just didn't read the instructions properly. :D
[LG Optimus L9 P760, P765, P768, P769] cmahendra:
Well I dont remember if anything is changed from previous flash folder to this one but I only got it updated from Angrywolf80. I will check for any difference in files. Please wait. :confused:

EDIT: Just checked both folders "RootFlash" and all the files are identical (no change, its same folder and files). Is it possible you got any file blocked up by any security software or firewall and may have got it repaired with new copy? STRANGE!

By the way I have just flashed V30C two days back with latest folder only.
[LG Optimus L9 P760, P765, P768, P769] kevev:
Thanks for checking. I think I did not allow local network during the Firewall popup. After doing this all my copies work.

A good note would be to have the firewall turned off.

Now I am stuck on P760 20B. The R&D Test Tool is not seeing my device in S/W Upgrade mode or booted to JB. Gonna build .bin & .fls files for 10G...
[LG Optimus L9 P760, P765, P768, P769] nikosma:
I have the same problem,the only difference in my case was that i can make online update from 20B to 20C.

Is that ok if follow the instruction to root my P768? Because I know P768 have a little bit different with the others.

No! dont do it. Download V20c France rom, extract bin file and edit that bin with my easy method explained in bin edit thread. then use in flashing with same kdz.

EDIT: In case the text you are replacing is in different location inside bin file, then you may CORRUPT the bin file and brick phone.

Hi, I tried to root my P760 using original V20C KDZ for POLAND and your BIN file for V20C Europe. I've followed the flashing procedure, done the quick magic, the ROM flashed, but no root. Then I've tried the KDZ with modification from your BIN file pasted into my extracted BIN, but again, the ROM flashed, no root (although whole files were identical -both yours and my edited original). So I've edited bin file according to AngryWolf80's thread, used it following your rooting guide, and... voila!

Download original V20C KDZ file for Poland and this BIN: LGP760_AP[11]_V20C_POL.zip

It works!

It seems there's something wrong with your BIN.

Hi guys,

Got here a P769 10G and I've followed all the steps and have all the drivers, host ips, everything in all the steps and etc, but I seem to get stuck between STEP 8 and 9.

At that point, after I press UPGRADE START, it tells me that the server is

under maintenance

. ( *EDIT, I did restart the computer to stick the host files, but still same msg with the 10g KDZ)

The KDZ I'm trying to use is the same that is on the phone...is that the problem?

Should I be looking to use the KDZ for the 11A? (as well as the BIN for the 11A, so I would assume)

(Edit: DLing the 11a and the BIN for it now, going to try it soon since I've got at least 1 confirmation that it works with the TMO version of the phone...crossing fingers)

Great ! Congrats! Thanks for confirming that you forgot a step. Some people dont do that.

Now tell us, was that really too hard?

Does this work for T-Mobile P769 upgraded to JB (P76920D)? I couldn't find the hex file for it in the 2nd post.

Thanks,

P769 V20D was not yet released as full 600mb downloadable KDZ. It was 350+mb ICS to JB Update file, so this method will not work for it at the moment.

But why you will ever need it? You can install V11A while rooting it with this method and install CWM. And then simply download and restore Nandroid CWM Backup of V20D from this thread. http://xdaforums.com/showthread.php?t=2136204
