Thread: Stock ROM
04-25-2011, 03:10 PM #1
Is there a stock ROM going to be released for the Optimus C? Seems we're the only ones who don't have one.
See post #15 for a way to revert to Stock.

Hopefully we'll find it floating around the Internet soon. Good find with that Gingerbreak. Was it that easy? If you can, post your results in the thread here: http://www.cricketusers.com/cricket-....html#post6635.

Alright, I was able to get a Xiona CWMA recovery installed using the following guide:
[Custom Recovery] Xionia Clockwork (CWMA v1.2518.6) - Android Forums
I'll work on getting a ROM set up and going and start a thread with a how-to.

Are you going to try to flash another ROM at the risk of losing MMS? I said in theory on another thread that you should have talk, text, and Internet. This is in theory because the ROM only changes certain things. It won't touch the PRL or other phone programming like your number... :-)

I'm going to flash as many ROMs as possible to see what functionality (if any) are lost. I know there are some ROMs for the Optimus S that still have working MMS, but we'll see. If all else fails, there's always a Nandroid backup to fall back on.
------------ ROM Testing Progress ------------
So far, all the ROMs for the Optimus S that I've tried have the following problems:
- Hardware buttons do not all work correctly (Up is down, Down is nonfunctional, Menu is search, etc).
- The touchscreen does not work.
That's all I could test for the S ROMs. No touchscreen = No testing
I'm starting to think that "Optimus" doesn't mean "Same hardware". I'll do some comparisons and start with the one closest in specs to the Optimus C.

I'm going to call Cricket tonight and see about a stock ROM release.

Wow thanks for the preliminary testing there. Cricket will probably act like you have a .... growing out of your forehead. Any attempt is better than no attempt though.

They were pretty straight-forward when I had my Ascend. Hopefully I'll get someone just as enthusiastic as the last guy I talked to. As long as we understand the warranty will be voided, what's the big deal, right? haha

I do like Cricket for the sole reason that they let us play with devices and put them on their network. chrisngrod is uploading his flashed Verizon USB modem video to Youtube right now. Shows how you can share your data profile with another device and get Internet on both....

Ok, I was unable to get anyone competent on the phone this time and I don't feel like sitting on the phone another three hours haha.
Anyone who has rooted and have yet to customize, could you dump your stock ROM, zip it up, upload it somewhere, and post a link to it? I'd do it myself but I didn't think of it prior to deleting most of the bloatware that comes stock.

Long story short:
1. Install and setup the Android SDK
2. Enable USB Debugging and connect your phone to the PC, install the drivers from
Drivers & Resources - LG Forum
- Use the one labelled LGAndroidDriver_Ver_1.0_All.zip for Cricket.
3. Create a folder on C:\ called lglw690-system-dump
4. Open a command prompt and type the following
adb pull /system C:\lglw690-system-dump
6. Paste the link to it here.
1. Root the phone using the Gingerbreak.apk that is stickied in these forums
2. Install a custom recovery. I was able to install Xionia CWMA using this guide:
[Custom Recovery] Xionia Clockwork (CWMA v1.2518.6) - Android Forums
3. Reboot to recovery and perform a nandroid backup
4. Pull the nandroid backup off your sdcard, zip it up, and upload it to a filesharing website
5. Paste the link to the file here.
Hopefully, they will both dump the stock recovery, also.

I think I can manage that just fine. I'll have a dump posted for you later today.

8/18/2011 - corrected instructions on how to restore your Cricket C back to stock 2.2.2. I have confirmed this works. I have performed these exact steps on my own C.
Credit for some of the instructions for resetting the Optimus C back to factory go out to mmarz (
) and 00_wrath_00. I have just edited their instructions and added some of my own experience with resetting my own Optimus C back to factory.
I HAVE TESTED THIS ON MY OWN CRICKET OPTIMUS C and restore back to factory including recovery and no root.
1. Download the package I have put together to restore phone to factory
2. Extract it into your C:\ directory such that KP500-Utils-EN.exe is located: C:\KP500-Utils-EN\KP500-Utils-EN.exe along with cab file.
2. Firmware and KP500-Utils-EN.exe should be located within the same directory
3. Make sure you have the most recent version of LG Mobile Support Tool Mobile Phone Support. Uninstall older version and re-install the latest if you do not already have.
4. Turn off your phone and take out the microsd card. * You can leave it in, but I don't recommend just in case.
5. Turn phone back on
6. Make sure you have over 60% charge and connect your phone with the USB
7. Make sure you have your phone in USB debugging mode by going to Settings/Applications/Development and tapping on USB debugging
8. Run KP500-Utils-EN.exe
9. Press the letter J on your keyboard and press enter
10. Type "LG-LW690" for Phone Model and press enter
11. Type "LW690ZV6_02.cab" and press enter
12. Type "LW690ZV6_02" for the Version and press enter
13. The updater in my package will open up and probably complain that the phone is not connected. Just click restart and the program will continue.
14. Allow the program to do it's thing. Your phone eventually should reboot with a screen that says it's upgrading.
15. Wait until the downgrade is complete and the phone reboots. Do not unplug your phone until the program asks you to exit.
16. For me, it went back to my home screen and did not loop on the animation screen. But if it does loop on the android animation don't panic. Pull the battery out.
17. Perform a factory reset by going into settings menu/privacy and click on factory data reset.
18. Perform factory reset.
19. Then wait. Phone will start up and animation will take a while till it gets to the Welcome screen. This brought me back to a factory Cricket ROM, unrooted.
