Well its not the battery and the sim. im a technician and u need is to replace its mouth piece inside/ or you can try opening ur lc vu and try to clean the surface where the mouth piece is connected.. clean it with an eraser (i.e. pencil eraser) because it will remove the dirt/stain thats prventing the signal of ur mouth piece to your phone. and for this matter I am 95-99% sure.

Lg vu is stuck on re-flashin screen


Remove your battery for a few minutes. If you use a SIM card in your phone. Remove it also.
Replace all & then attempt to power back on. If this continues; try a new battery.

Will a boost mobile sim card from prepaid phone work in my unlocked lg vu


Yes it should if the LG mobile phone is unlocked. If not, when you insert the Boost SIM card in the LG it will ask for a Secutity Code.
If the SIM card won't work in the LG, please get back to me.

I dropped it and now my lg vu wont read my at&t smartchip. plz help.


Turn off the phone. Take the battery and Sim Card out. Make sure there is no dust or dirt of where the Sim Card goes. Blow air (from your mouth) of where the Sim Card goes. Sometimes rubbing a soft pencil eraser on the Sim Card contact points can help. Then place the Sim Card back in the phone. Make sure it is in the right position; copper contacts facing downward. Put the battery back in your phone. Turn it on, and see if the smartchip rejected goes away.

If not you may need to contact your Phone Provider’s Tech Support to troubleshoot and confirm that you may need a PUK reset code to register or you may need a new Sim Card, as they do fail from time to time.

What does it mean: insert a smart chip?


Try cleaning the contacts on the sim card. if that doesn't work go into the phone store and ask for a replacement sim.

Where do you put the memory card for a LG Vu


you slide off the back of the phone. Remove the battery. Then take out the sim card. Right beneath that is where the memory card is supposed to go. You can easily tell if it's in or not because you have to push it down and hear a pop. Hope that helps, I've had mine for three weeks now!:)
