I can confirm this is working for my LG-P705f (Uruguay Antel, unlocked). A few items I'd like to point out though: 1. In the software updater program the phone mode should be EMERGENCY. 2. I had to run it several times. The software will reboot the phone and wait for the phone to turn on before finishing the update process. Since the phone has the battery removed it will not turn on. You should have enough time to shut down, insert the battery, then boot up (with the USB cable still connected). Then the update process will finalize correctly. 3. After updateing my phone would be stuck on the LG logo screen at startup. To fix this you need to boot up into recovery mode (Both Vol + Home + Power buttons). CWM is included in the rom so once in it you should do a Factory reset and also wipe the cache. 4. Rom has most languages, including Spanish.
