Here is a recovery for you guys! Tested Working on xda by Joesph Mother
Let ThundeRom for LG Optimus T commence. LG-Optimus info
Please check md5 of 82deaeec44c9b6b7095efcfa31fee099 prior to flashing
Only thing I’ll change is remove test naming fyi.
To install extract the recovery.zip (linked above) and flash_image.zip (from opt s post) and copy those to the ROOT of sdcard.
To flash recovery from root # shell do these commands. If install-recovery.sh doesn’t exist on your phone just move to next step.
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
# flash_image recovery /sdcard/recovery-RA-GNM-OPT-T-test.img
# reboot recovery

Optimus T – Changing a Hemorrhoid To An Android
As an Android Newbie, this is my way of giving back to the community. I came very close to bricking the phone. Do not blame me or anyone else if you try the following and it does not work.
The original carrier configuration was a pain in the butt a true Hemorrhoid. I had to remove it.
Initially I could not figure out or understand what is required to change to Android 2.3.3. The biggest problem was some of the terms and having to piece together many different sites and threads.
As a Newbie the key thing to understand is that your phone (Optimus T at least) has an in built recovery mechanism. In which all settings and the system return to a default carrier setup. This recovery mechanism has to be OVERWRITTEN with a custom recovery image. Note this custom recovery is permenant as the carriers recovery was OVERWRITTEN. The only way to get back to the carrier recovery is with a utility called KDZ_FW_UPD from LG and placing the phone into Emergency Mode. Emergency Mode is different to Recovery mode. The custom recovery will allow you to install various different versions of Android.
1) Before you start. BACKUP all your data. Make sure you have copies of everything you need and value. Nandroid and Titanium Backup were recommended to me. Of course being a Professional I didn’t. I dove straight in and failed. All was not lost I discovered Emergency Mode!. Also as the phone was I was not risking any personal data.
2) Prepare for the worst. Find and install on a Windows PC KDZ_FW_UPD.exe. It is a utility from LG Electronics. Ensure you also have a file called V10L_00.kdz. I believe this is the firmware that is flashed to your phone. You will need these when all else fails. This utiltiy and firmware can unbrick the phone when only Emergency Mode can be reached. KDZ_FW_UPD loads the firmware file through the USB cable to the phone. Emergency mode is reached by presing and holding Volume Up, Back Key and Power On at the same time. A yellow screen with the words Emergency Mode ! will be seen. I had to use Emergency Mode twice. It takes some fiddling to get it to work always reboot everything and start from scratch, with anti virus off etc etc and it should work. It took eight hours of fiddling to get it to work for me. Look on the web for more tips.
3) Before you can install a Custom Recovery you need to “Root” the phone. Rooting means you can gain SuperUser (SU) access to your phone. You will have full permissions to do everything, including shooting yourself in the foot. Be careful. I found and used an App called z4root to gain root access. It has been removed from Android Market so you have to find it on the web elsewhere.
4) Once you have root access you need to install “Android Terminal Emulator” App. This will allow you to get to the command line of the phone and enter super user mode by typing su.
5) To install a custom recovery follow these excellent instructions http://www.lg-phones.org/lg-optimus-t-custom-recovery.html
Fat fingers and lack of reading glasses caused many problems typing. Have patience. You only have to do this once and then you will be able to try various Android builds.
6) Now you have a rooted phone with custom recovery you can try custom Android builds. I tried “void” and it worked, but the following is the one I have stuck with http://forum.xda-developers.com/showthread.php?t=946354. Follow his instructions very carefully. You need to run two zip files in recovery mode to install this CyanogenMod 2.3.3 build.
7) Assuming you have everything working you may have noticed the lack of Apps. You did backup everything did n’t you.
Good luck and Thank You to everyone who takes the time to post, code, share knowledge and contribute.
