also require the adb sidelod supportable ROM.
read my post, it tells how to get it back to sprint rom...

1) Get custom recovery on your phone
2) by using adb side load sprint rooted stock rom ( so, it would become a sprint G2 again from being an t-mobile g2, that's the reason it fails in lg flasher tool)
3) Now, once it flash successful, boot into downloader mode. Then flash stock sprint rom via lg flasher tool.

if sideload doesn't work (sideload didn't work for me) I just used adb push instead of adb sideload.

you just adb push "name of rom" to /sdcard/0. if you are bootlooping the problem is that you didn't downgrade aboot and maybe forgot to downgrade radio. You need to do this: adb push the zv8 radio and zv7 boot to sdcard in recovery to /sdcard/0

for example in my case:

Type adb push zv7-aboot.img /sdcard/
Type adb shell
Type dd if=/sdcard/zv7-aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot

then adb push /sdcard/0
after you downgrade your aboot with the above commands, flash the cm11 rom and gapps. then flash the zv8 radio. You will then be able to boot. Hope this helps anyone that needs specific instructions on what to do if they softbricked their g2 on zva and didn't downgrade aboot or flash zv8 radio.

Root via adb, and flash twrp recovery. You have done quickly coz random boot.

After success root and flash twrp, you download stock rooted rom sprint ekstension zip.
Flash via twrp, and you back to fasboot mode, bootloop. But your g2 was sprint again.

Download rom back to stock, fill dll and tot file, flash via lg flash tool. Awesome, you be back to new handheld.

Sorry my english so bad...

Need advice. Been reading all of the threads but still coming to a dead end.

1. Phone was previously running 2faced G3 Rom.
2. Installed recovery using AutoRec but failed.
3. Now, my phone boots to the Security Error screen and shuts down.
4. I can not get into Recovery.
5. I can get into Download Mode and run LG Flash Tool v1.8.1.1023.
6. LG Flash Tool does not allow me to return to stock using TOT because of "Device Model is different" error message.
7. Per suggestion above, I tried flashing T-mobile KDZ using LG Flash Tool 2014, but it does not recognize my phone. It keeps waiting for the phone to connect.

Any suggestions on what I should do next? Any help would be appreciated.
