hi everybody here is a way of how do downgrade your cell phone You'll need to get the stock (official) 1.6 firmware as a update.zip file suitable for your particular phone model. To be sure that it isn't some modified version, ask your manufacturer (LG). Place it to your sdcard and kick it through the bootloader for manually updating. The procedure differs for different phone models. So check with your manufacturer (LG). People on xda-developers forum might have backup of such files and know the procedure. But they usually show interest in HTC based android devices. Do try your luck there if you can't get it from LG straight.
