Root Restoring stock firmware

Hi all,

Some of you may know me from the LG Spectrum forums. Here is a method for returning to stock that should NOT erase your IMEI and is much easier then setting up for flashing .tot .

NOTE : I do not own a LG OE, but the instructions should still work. If anyone runs into an issue, please let me know and I will work with you to correct it.

EDIT: This method is currently on hold until I find a copy of the .cab that actually contains the .dll needed to flash it. It should have been inside the cab file, but it was not.

Here is instructions on how to flash a new firmware. If you do something wrong, you will brick your phone, especially if it's during the final steps as flashing the cab actually deletes your recovery partition before flashing the new one.

Tools needed:

KP500 (http://androidfiles....ls/LG_Tools.zip) - Personally hosted, so please don't hammer the site

LG Update tool from LG site (also includes link for drivers) http://www.lg.com/us/support-mobile/lg-LGVM696#software

.cab file containing your firmware
V4_01: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGVM696/AVGMBK/VM696ZV4_01/VM696ZV4_01.S4_01.P61007.cab

An internet connection on the PC you are working from. The LG tool needs an internet connection while flashing the phone or it will fail. If you have a firewall asking if you want to let the LG Tool talk to the internet, let it.

Instructions:

Charge your battery to full, not just 80% or so.

Run the driver package and let it run its course. It will appear as thou nothing is happening for about 30 seconds, then the installer will finish running. Then set phone to Debug mode and make sure all additional drivers install correctly. If you have adb on your PC, you can test your connection buy running ADB shell and seeing if your phone connects correctly

Go into your Windows Device Manager and disable the device under Modems -> LGE AndroidNet for USB Modem

Remove your battery and remove your memory card.

Reboot your phone in "Download Mode" (re-insert your battery and replace the back plate. Hold down vol up + vol down. Plug in usb cable while holding both buttons.)

I highly recommend using the official cable that came with the phone when doing a flash and not being on and USB hubs.

Extract KP500 tool into a directory (i.e. C:\KP500)
Move your .cab file to the same directory

Run your KP500 file as administrator
Choose I "Flash with assistance (file .cab)
Phone Model = VM696
Input the full path to your cab file including .CAB at the end (i.e. C:\KP500\VM696ZV4_01.S4_01.P61007.cab)
Input the full file name of your cab (aka version) without the Cab (i.e. VM696ZV4_01.S4_01.P61007)

Watch as the LG update tool pops up.

It will most likely tell you that your phone is disconnected. This is normal and to be expected

Click Restart.

It will find your phone and go thru extracting the cab file and then extracting a .bin file.

At this point if you did something wrong with driver setup or not disabling the modem driver, you will get a page error. If you did it right, you will get a percentage indicator that goes past 15%. Every so often a message will go by about "model dll message not found". This is normal.

Wait for your phone to finish flashing and let it reboot on its own. I did not do a factory reset and everything came back as it was, but with a new firmware version. You may wish to do a factory reset just to be safe.

Enjoy the fact that you can now recover your phone if you do something wrong (in most cases)

What browser are you on? If it's IE you may need to look at the source code for the page you are viewing. If it's firefox, it should show up something.

Edit : If using IE, do a file -> save as -> webpage, source only . Then open up that file that you saved in wordpad. It should look like this:

Code: 
<?xml version='1.0' encoding='utf-8' ?>
<response req_cmd='auth_model_check' status='OK'>
<auth_model_check>
<result>OK</result>
<esn>"removed"</esn>
<model>LGVS920</model>

<cs_em_uri>N</cs_em_uri>

Firefox gives me the following when I check page source...

<?XML version='1.0' encoding='utf-8' ?>
<response request_cmd='auth_model_check' status='fail'/>
 
New to all this but want to help out, is this safe or will Virgin Mobile be watching me after using this link? LOL And this file it gives isn't IMEI specific so it's safe to give the link it gave me here on the forum? Don't want my IMEI stolen. :P

Edit: I just changed 1 digit on my IMEI (paranoid, but still seems to be my same phone VM696Z4) and it gave me cab link files. Uh, answer on my above questions? :P
 
No vm won't be watching you. The file should not be specific to you phone but check the file name as it may contain your meid. Give it a try and see if it works for you

Nope, they can not see your IMEI. Only LG sees it and they just see it as their update tool checking for a new .cab file. Can you post the link to the cab you received?
 
First post updated. Please let me know how the success rate on this goes. It works flawlessly on the Spectrum and from what I can tell, it is LG's stand procedure for updates now.
 
Got an error when attempting.

Do you have a firewall blocking the lg update tool? That seems to be the most common problem related to that message.
 
I'm downloading the .cab as well to make sure all the files that should be there, are actually inside the thing.
 
Ok, sorry that took so long. Was off running errands. The reason this will not flash is that the .cab file does not contain the .dll required to go any farther. All that is inside is the .wdb and .wdh file. I'll dig around in their server a bit and see if I can find a better .cab . As it is, I already found the V5 cab, but it's under lock and key right now.
 
Blind, that .dll is different then what should be in the .cab file. Still no luck finding a .cab with the .dll, but I did find a link to your V5 upgrade that is being worked on. I can't download it thou as it gives a "forbidden" message.

Do you still need this DLL added? I know how to ;) I've done it before for the Optimus V.

I found the link to a DLL here: http://androidforums.com/4625910-post1.html

I know a way to get the .bin file extracted but I need someone to work with me via teamviewer who owns this phone. I need this bin extracted to rebuild the firmware.

I just need one person to work with me via teamviewer.
I won't be able to do this till tuesday.
First person who says they can help and is available Tuesday will be the one helping me.
 
Hello guys. I am little confused here. Is there a proper guide to flash the firmware for the lg optimus elite. I have seen so many different things in regards too this matter, I don't know if it helps but i do have my msl for the phone
 
I got my LG Optimus elite a couple days ago and it was fine. I decided to root it and that went smoothly. One day i heard of rom manager so i download it and directly went to backing up current rom,then it went straight to this screen. It said LG at the top and at the bottom in a box "Do Not Disconnect cable" and it wasnt even connected to a cable.I think it was because i didnt download the flash clockwork recovery mod or that i didnt have a internet connection just wifi.What ever it is, nothing is responding and i cant charge it any more, it only stays on when it plug in the charger or on the computer with a data cable.and on the computer it says when connected The drivers for this device are not installed, and i tryed updating them but nothing worked. I dont Know if its bootlooped or bricked but PLEASE HELP.
