Accidentally water spilled on my Optimus one. I switched it off and removed the battery. Wiped and Dried. Kept the mobile unused for 2 days. Now when I switched it on, it automatically going to safe mode and my back button not working too. When I switch off and remove the battery and switch it on, a yellow screen saying Emergency. Now when I try to charge the mobile , power on , mobile going in safe mode . Battery status showing 81 percent on some boots and very low battery on some boots. When I try to get into normal mode, volume button automatically increasing and decreasing its volume and I cannot use any apps too. Though it is installing but not getting reflected in menu or in the applications of uninstaller . Factory reset also has no effect and doing the same thing and bit of googling revelead that mostly my motherboard would had been gone.
What will be the cost of replacement of motherboard or any fix to this ? I am planning to take it to the service center and what if LG guys say that motherboard needs to get replaced ? Is it a wise idea to replace the motherboard or go for the new mobile ?
