[LG Optimus 3D] drastic00:
April 24: XBSA vR3D is here! Steps specific to VR3D will be in PURPLE. Let me know if there are issues. You need to be on ICS and rooted with custom recovery for XBSA ROMs. His rooted v28B files give you that.

This guide is for Windows 7 (It is almost the same for Windows xp, except in how you choose the omap4 driver).

New! Here are some tips for installing unsigned drivers on Windows 8 (Thanks sda.171!):

I just wanted to add something for fellow Windows 8 users following your guide. By default, windows 8 does not allow driver which are not signed to be installed. You wont even be prompted to force install it. It will deny the installation without your knowledge (this happened to me and I had no clue). In addition to installing every app as administrator. You have to disable driver signature verification on your windows 8 computer.

To do that.

Go to PC settings > General > Under Advanced startup , click restart now > at the boot up screen click 'troubleshoot' > advanced options > startup settings > restart > then press the corresponding number to temporarily disable driver verification (it was 7 for me).

Then do all the driver installing as stated in the awesome guide. If you restart after the disabling the verification is enabled again. It works for only one boot and has to be done again if required (in case you restart after disabling). The verification has to be disabled for successful installations of the drivers u install or else it wont work for you on windows 8.​

The original guide to setting up LG Flash Tool, from Marti701 with translation by adixtra. THANKS to THEM!

Thank you also to kideskimo for his guide to ported ics on LG Thrill...

I might still be fiddling with GB if it were not for finding that in December 2012.​

...but this is written for noobs like me!

Thanks to all who are listed here and and anyone else who helped me learn all this!

Thanks especially to xbsall for all the hard work he puts into these ROMs!!!

This guide was MUCH longer until the official ICS v28b for Optimus was released. The official update eliminates a bunch of 'fix it' steps that were previously necessary to keep 3D functionality and other issues; it makes things generally easier to do. So, hit the THANKS button for xbsall here: http://xdaforums.com/showthread.php?t=1963847

***OBLIGATORY WARNING: Though worth it, and totally awesome, flashing ROMs to your phone WILL ERASE EVERYTHING. Remove your Micro SD card! Backup your internal SD memory! Save a copy of everything in your internal phone storage that you want to keep! If you make a mistake and 'brick' your phone, it is fixable in almost all situations. BUT, even if you flashed a corrupt file, YOU DID THAT.***

You will need to download 5 files for this process:

NOTE: some of these zips contain system files. Windows Defender and other antivirus programs will prevent some of these from extracting correctly or may cause file corruption.

1) "LGFLASHTool Pack": From here: http://d-h.st/WL2 from me (Called "BagofGoodies").

2) LGP920_110622.dll: Get it here: http://d-h.st/FcP from me

3) Choose one ROM (Do not mirror these links):

XBSA vR3D with Ac!d Audio Engine and Nuance Voice Control:

(DO NOT extract this file): XBSAVR3D.zip:

from here--> https://mega.co.nz/#!Pg5RFTiI!F8dTrFwlNA3JOsngdYY2aAOsjLFtXgEInlndikFtA40

or here--> https://mega.co.nz/#!Cow0xYxJ!OzcVaGvPwAr5TNF2ogsCeTRXQYQ804z05TT_Ns-kqtI

or here--> http://www.putlocker.com/file/1B0B002872D69099 from xbsall

**OR**

XBSA v8 with Ac!d Audio Engine:

(DO NOT extract this file): xbsav8.zip--> http://d-h.st/J9o from xbsall​

4) Choose one official LG v28b ICS file (.bin and .fls files included) with root and custom recovery (Do not mirror these links):

For XBSA vR3D get this file:

LARGE partition, rooted official LG ICS v28b with preinstalled TWRP: 28brtlarge.rar--> http://d-h.st/dxl from xbsall

**OR**

For XBSA v8, get this file:

Rooted official LG ICS v28b with preinstalled TWRP (NORMAL partition size): XBSAV28BROOT.zip--> http://d-h.st/Kxn from xbsall

NOTE: You may also install XBSA v8 using the LARGE partition v28B rooted .bin file included in the ABOVE link BUT you CANNOT install XBSA vR3D using the normal partition v28B .bin file included in THIS link.​

5) Also get this folder:

You will ONLY need the driver in there for step f.4.4. omap4boot-for_optimus-v1.21.7z--> http://xdaforums.com/attachment.php?attachmentid=1536163&d=1354636466. from wkpark.​

EXTRAS (Do not mirror these links):

LGE email app for XBSA vR3D:

After installing the vR3D ROM get this .zip file and copy the contents to system/app on your phone using a File Explorer (then reboot): sdcard.zip http://d-h.st/zTO. from xbsall

More languages for XBSA vR3D:

After installing the vR3D ROM get this .zip file and install it with TWRP after installing the vR3D ROM: MULTILENGUAJE VR3D.zip http://d-h.st/wQV. from MarcoSuper7

​

Unpack all zips EXCEPT the zipped XBSA ROM file you chose to a folder on your hard drive.

NOTE: some of these zips contain system files. Windows Defender and other antivirus programs will prevent some of these from extracting correctly or may cause file corruption. Temporarily disable these when extracting any files or you may not be able to find some things you will need!

What else do I need?

***Sync Cable**

A SYNC (not charge) cable is essential. One noob problem early on that I had was not knowing the difference (my phone was second hand and came with no chargers or cables). I could not figure out why the device would not connect. Unless the connector on your phone is physically broken, it is likely the cable is not a sync cable. Not all micro USB cables are the same! Some will only trickle charge your phone and not data connect to PC. If you paid $2 for a cable like me, it probably is not a sync cable. If you have connected to pc before to copy music or other stuff, that is the cable you will need...

**Charge your phone battery!**

You MUST have a well charged battery. Some of the install processes will use a sizable chunk of battery power to implement (~10%). If the battery runs out during any of the install processes, your phone may be rendered unusable!

Now that you have read all of the above and are prepared,

we can begin:

1) Set up drivers so the phone can be detected in LG Flash Tool:

A) Uninstall any LG Drivers on your PC:

a1) Open Programs and Features through Control Panel

a2)Find any drivers called "LG United Mobile Driver." Right click and select Uninstall, let it work.

a3)	Reboot your pc!​

B) Be sure you disabled antivirus/Windows Defender, etc. before unpacking these files.

C) Install OMAP4430 by running "OMAPFlashInstaller."

NOTE: if you have WKPark's custom bootloaders installed on your phone you may need to SKIP running the OMAP installer, or uninstall it if you did run it (if you don't know, you probably don't have it...), but DO link the driver as in f4.

D) Install the two LG Drivers in the “LG United Mobile Drivers” folder: These are “LGUnitedMobileDriver_S497CA20_WHQL_ML_Ver_1.0” and “LGUnitedMobileDriver_S497MA20_WHQL_ML_Ver_1.0” The second one will warn it is unsigned, choose to install anyway (you will have to insist on this a few times here).

E)	Reboot your pc!

F)	Install PC/phone drivers:

f1)	Shut down your phone. Remove external sd card, SIM card and battery.

NOTE: Please be advised that this section (Part 1 here) can be VERY fiddly to do, especially part f6. You may need to do this several times to get it right. Please be patient and keep trying. It is highly recommended to have the volume up on your PC, so that you can hear the drivers installing. Once f6 is done properly you will hear the installation sounds and it will become clear (finally) when everything is correct.

f2) Open Device Manager from Control Panel

f3) Hold volume up on phone and connect to USB port. Keep holding volume up.

f4)Look for "OMAP4430" blinking on and off in Device Manager with a yellow question mark under "Other Devices." (You can let go of the phone). If you do not see it, look for "TI Boards" blinking in device manager and quickly open the arrow. Then uninstall that OMAP4430 (right click, check box to uninstall device and driver, confirm), disconnect phone and reconnect with volume up. Then...

f.4.1) You will need to 'catch' OMAP4430 (with yellow question mark) by right-clicking on it when it appears under "Other Devices." Choose "Update Driver Software."

f.4.2) Pick "Browse my computer for driver software." Then "Let me pick..."

f.4.3) Leave "All..." selected under Devices. Then "Have Disk."

f.4.4) Navigate to the omap4boot-for_optimus-v1.21 folder and choose "omap_winusb" in the usb_drv_windows folder.

f.4.5) Windows will warn the driver is unsigned. Install anyway. An OMAP4430 device should appear under the list of devices. Confirm the selection. Let the driver install.​

f5) Disconnect the phone from the PC. Again reconnect it to PC while holding volume up.

f6) You should see a popup at the bottom of your screen about drivers installing (the LG USB drivers). (If you do NOT see drivers installing, disconnect phone again, reboot your pc, and again connect it without battery while holding volume up). When you do see drivers installing, let go of the volume button. Click the popup on your PC screen to see the install progress. Let it finish. Leave the phone connected to PC.

f7) Look for “LGE CDMA USB SERIAL PORT” in Device Manager. Right click on it and go to Properties

f8) Select the "Port Settings" tab and click 'Advanced'.

f9) Change 'COM Port Number:' to COM41. Click OK, then OK again.

f10) Disconnect your phone from the PC. Your phone and PC are now ready for the flash procedure. TIP: Leave your PC set up this way, and the next time you need to flash, Step 1 will be already complete!
​

2)	Flashing rooted ICS v28b:

A) Install LG Flash Tool by running "Setup_LGFlashTool_1.1." Let install but uncheck the ‘open LG Flash Tool’ box (don’t run it yet). The package comes with version 1.2, but 1.1 is what I used.

B) Copy the file ”LGFlashTool” from the “FILE.ZIP” folder over the file of the same name into the ” LG Flash Tool 1.1” folder. This will unlock the program.

C) Right click on "LGFlashTool," found in the same folder you just copied into and choose "Run as administrator."

D) Check the box that says "Select Manual Mode."

E)	Click the "..." button to the right of the "DLL" field, then choose "LGP920_110622.dll" file you downloaded. This file helps Windows to write the correct information to the phone.

F)	To the right of the "S/W" field, choose "Add" and navigate to/select "28bROOT_AP.bin." If you are installing XBSA vR3D, instead choose "28bRTbig_AP.bin" This is the official ICS file, but with root access and TWRP recovery.

G) Be sure the button for "USB" is selected. Click OK.

H)	Choose the port settings icon that looks like a serial cable.

h1) Check Port 1.

h2) It should select the first 3 check boxes when you do this; "16 Ports," "Port 1 ~ Port 16," and "1" should be checked.

h3) Click OK.​

I) Click the yellow arrow (start). You should see "Ready!" at the top left.

J) Insert the battery into the phone. While holding the volume up button on the phone, connect it to the pc with the sync cable. The phone should start flashing (i.e. LG Flash Tool will start writing the file). NOTE: if Flash Tool will not connect, try holding volume up, connecting the USB/sync cable, and THEN connecting battery (while holding volume up). Don't touch it until the process is complete. Once Flash Tool resets the device, it is OK to disconnect the phone after 10 seconds or so (let it complete to 100% if you are not sure). FYI: If you continue to leave the phone connected, Flash Tool will eventually say 'failed,' but that's OK.

K) The phone will NOT boot up completely. There may be a message about unsuccessful encryption, OR the phone may stick at the LG logo. Long press power (several seconds) to shut off the phone. Hold Volume Down. Continue holding Volume Down, then also press and hold Power (for about 3 seconds). You should get a black screen with white text about factory resetting. Press power twice to confirm. Let it reset and boot up.

L) Set up the phone (i.e. follow the prompts to start the phone for the first time). If you are installing XBSA vR3D, at this time you MUST go into Android Settings/Storage and ERASE INTERNAL MEMORY. This prepares the internal memory for the large partition size required for vR3D compatibility. Now power the phone down again.

M) Next we will flash the baseband (.fls) file (NOTE: you can also also do this part later, after installing the ROM in step 6). Redo steps 2C through 2J. But replace "28bROOT_AP.bin" with "28bROOT_CP.fls" in LG Flash Tool. If you are installing XBSA vR3D, instead choose "P925_CP.fls" The process of flashing a baseband will NOT complete to 100% in LG Flash Tool (It will say 'failed' after about 40% progress). That’s OK. I got to 155 seconds and it worked.

N) If you have connection problems in your country after setting up your APN (Step 7), you may need to get another baseband from here: http://xdaforums.com/showthread.php?t=1974734. Download the file you need and repeat steps 2B through 2J with your preferred file.​

3) Shut down your phone, reinsert your SIM and external (micro) SD, and reboot it. Let it scan the sd card/media, etc. for a few minutes until it is ready.

4) Optional: You can now use an app from Google Play with root access, like Titanium Backup, to backup all the stock apps. This is convenient if you want to recover any of these after installing the XBSA ROM.

5) Optional but Recommended: Use TWRP to make a 'nandroid' backup. You do want to save all the work you have done so far, right? Restart your phone in recovery mode through the P940 Recovery app that is now on your phone. Allow Superuser to proceed if necessary. Your phone will boot into TWRP. Select "Backup" in TWRP. Choose a name and location for the backup, hit enter on the keypad, then swipe the slider to start. Let it backup and then reboot system. You can use this backup later if you want to revert to rooted stock v28b ICS. Just return to TWRP, wipe Cache, Dalvik, do a Factory Reset, then choose Restore and then the backup you made. Swipe to confirm, your phone will be restored to this point.

6) Installing XBSA v8 or vR3D: Doing this step will update your firmware to v30A (v30C for XBSA vR3D) and install the ROM.

A) Now that you have TWRP as the result of all the previous steps, this will be a relatively simple process, but (as in all steps here) you MUST do them in the correct order and NOT skip anything!

B) First, transfer the file "xbsav8.ZIP" (or "XBSAVR3D.ZIP" if you are installing XBSA vR3D) to your phone's sd card. One way to do this is to connect USB as mass storage. I prefer to use the external sd card for zip files. Do not extract the file, leave it in compressed (zip) format.

C) Get to TWRP by pressing Volume Down when the touch keys on your phone blink during bootup

OR

Find the P940 Recovery app on your phone (it was installed with xbsall's rooted v28b). Start it and choose Reboot to Recovery/Yip...

D) First be sure you have the ROM .zip file copied to your phone. Then, you MUST perform these wipes or you will have problems later! Do not reboot your phone after doing the system wipe without installing the ROM or the phone will not boot!!

d1) Select "TWRP Wipes."

d2) Select to wipe "Cache," then swipe the slider to confirm the wipe.

d3) Select to wipe "Dalvik" cache, then swipe the slider to confirm the wipe.

d4) Then select "Factory Reset" and swipe to confirm.

d5)	Wipe "System" and swipe to confirm.​

E) NOW, install the XBSA ROM:

e1) Go back a screen in TWRP (tap the up-pointing arrow icon) and tap "Install"

e2) Navigate to the .zip of the ROM you chose to install (v8 or vR3D) and tap it.

e3) Be sure the correct file is selected (read the information), and when you are ready, swipe to confirm the installation.

e4) When it is finished, tap "Reboot," then "System."

e5) If you did the required wipes, there should be a warning that no system is present. That's OK, it will be installed upon reboot. Confirm the reboot (swipe), let android update, go through the Android first time setup menus, then LET IT SETTLE a bit so all files install properly (5-10 minutes).

e6) Finally, reboot again, and let the phone settle again.​

7) Set up the APN (Access Point Name) for your network. Now you are basically ready to use the phone without having to do any more major installations, so you can set yourself up to make calls and data connections according to your provider's APN information (in System Settings, More.., Access Point Names, New). You will need to Google this information. Just remember to tap the menu button and hit save after entering the information required by your provider (I use Straight Talk in the U.S. for my AT&T LG P925).

8) Optional but Recommended: Use TWRP to make another backup after you set up your phone as you like.

That’s it! You now have the best available ROM for the Optimus/Thrill because it keeps the 3D functionality and has AWESOME AC!D Audio!!!! And now Nuance gives vR3D some really cool voice control options ripe for modding! You DID buy a P925 or P920 because it has 3D capability, right? Right??? Now go show it off!
