    It enter & hold on the Android Logo with Red triangle, without any menu or message, just this error logo (press Vol Up then Vol Down is No response)

    Can I know how to let this pass this “Android Logo with Red triangle” and go to LG Menu to reset the phone

    or Should I use B2CAPPSetup from PC? (I haven’t installed yet)

    Thanks a lot


    • Hi, the default way to do hard reset at LG Optimus L9 are using Power button + Volume Down button + Home Button key. All 3 keys should press and hold together about 10 seconds, then you will see the hard reset menu to follow. If you still can not access this menu, the please try again carefully. This steps available for standard LG Optimus L9, but maybe can not work for some root or custom ROM smartphone.

      • Hi, if your phone get hard bricks or hardware problems, then the hard reset using hardware key combinations can not work as well. Please consult with LG authorize service center for further check.

  2. Hi, i m unable to connect wifi in my LG P769 however I can use the wifi in my HTC. I’ve done twice factory reset but no luck. Switch off and on the modem. I can see some names in my phone but i can’t see the name of my wifi. If i insert manualy the name of the wifi it says “not in range”.

    Please help me.

    Regards Pooja

    • Hi, in some case this problems happen because the wifi access point or router use specific security, please change the security access of your access point maybe to WEP to test weather it can work or not, but of course this will make your Wifi access point become more vulnerable. However, you can also test using different Wifi access point, maybe at different location just to make sure your LG Optimus L9 wifi still can work normally, not get hardware trouble.
