Flashing LG signed Firmware

[liteon163]

Thanks for the link. I'm slowly amassing the files I need to finally flash Broken Out (now 2.0).

I'll eventually back-up some other stuff and make the leap.

Yeah, yeah Isaiah. "Just do it, lite!" I know.

thanks guys for all the support going to put broken out on now... cause i hate the lg stock it sucks .... last question i saw how broken out 2.0 is using the z5 beta build can i flash it over the stock zv4 that i'm currently running or do i have to go to the z5 beta build and then flash broken out....thxx

You can just go right to Broken Out. Because it's a ROM, it will completely overwrite your stock ROM. There was is no need to make any sort of incremental upgrades.

First post updated with V6 links and warning about flashing this if you are stuck in a CWM boot loop.

The only thing you have to worry about when flashing Spectrum Roms is to make sure you do wipe everything IF you are moving from V3, V4, V5, or V6 to a different build type. If you are going from V4 to V4, no need to wipe first, unless the Rom dev says you need to.

I was wondering I keep hearing half Ass answers and was curious if the LG recovery tool can bring a phone on BO 3.0 with blitz kernel and cwm back to complete stock.

.Cab files are more for unbricking then trying to just go back to stock. Please use the nandroid method in the other forum you are posting to as you run less chance of bricking your phone.

This worked great for me. I want to sell this phone, but no matter how many times I tried to wipe all partitions in CWM recovery it always booted up with nothing changed. Even all my data was still there. I'd never seen this on any other phone.
I followed the steps in this tutorial and it looks like I'm all good to go now.

Thank you!

thank you

DO NOT FLASH THIS IF YOU ARE STUCK IN CWM. IF YOU KEEP BOOT LOOPING INTO CWM, THEN FLASH THE BOOT LOOP FIX FOUND HERE. YOU WILL BRICK YOUR PHONE OTHERWISE:

I've decided that this should be in it's own thread as it is relevant to most of the work going on right now and should not be buried inside of another thread.

Here is instructions on how to flash a new firmware. I take no responsibility if your mess up your phone in the process. 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.massivefilehost.com/LG_Tools/LG_Tools.zip) - Personally hosted, so please don't hammer the site

LG Update tool from LG site (LG Mobile Support: Find the Latest Drivers & Product Guides | LG USA)

.cab file containing your firmware
3.02 - http://csmg.lgmobile.com:9002/swdat...K/VS920ZV3_02/VS920ZV3_02.S3_02.P58012.R5.cab
4.04 - http://csmg.lgmobile.com:9002/swdat...K/VS920ZV4_04/VS920ZV4_04.S4_04.P58012.R5.cab
6.00 - http://csmg.lgmobile.com:9002/swdat...K/VS920ZV6_00/VS920ZV6_00.S6_00.P58013.R5.cab

Unified Verizon Drivers from LG Site or from your phone. (I went to grab the link from the site, but the Verizon drivers are no longer listed there. Putting your phone into charge only mode will activate a special area of the phone and Windows will show up a new drive containing the USB drivers)

An Internet connection on the computer you are flashing with. If your fire wall asks if you want to give the LG tool access to the internet, then let it. It will fail to flash otherwise.

Instructions:

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

Run the driver package and let it run its course. 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 VZW 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 = VS920
Input the full path to your cab file including .CAB at the end (i.e. C:\KP500\VS920Z3_02.S3_02.P58012.R5.cab)
Input the full file name of your cab (aka version) without the Cab (i.e. VS920Z3_02.S3_02.P58012.R5)

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)

can someone please help me, i cant find a download for the Verizon Wireless Software Upgrade Assistant anywhere on the net, and i cant get it from the phone as it is stuck in a bootloop so i cant follow this tutorial. i do have access to revovery mode and dl mode
i have cwm 6.0.1.1 and cyanogenmod 10.1.3
lg spectrum vs920

 

[UsualNoise]

I too can't find the original LG flashing program used here, the current one (Verizon Upgrade Assistant) doesn't seem to be doing the trick. Does anyone have the original version used in this tutorial? I'd greatly appreciate any help.

Thank you Neph. My phone was in Security Error and I could recover my phone by your instructions. Great work
