Question about LG CU500 Cellular Phone

1 Answer

Cu500 in Brazil

I bought a LG CU500 in the USA from ebay and it was advertised a being unlocked. It was an AT&T cingular phone. When I got here to Brasil I put in my chip from TIM. and the phone just said it disconnected immediately. It has a signal but simply doesnt function. No calling or recieving abilty. I also tried a chip from a different orovidor Claro and it still doesnt work. I took it to tech assistance and they said it needs a program in portuguese and they cant locate it. Do you have any advice on what I can do? Is there a firmware?
Thanks John

    Thanks, Cell phones are about 65 times cheaper there and this was the first time I have seen this problem. What a shame. Well, thank you for the help.

  • John Brill Jul 26, 2008

    i meant 6 times cheaper ehehhee

  • John Brill Jul 26, 2008

    are you guessing or do you know about this for sure. Because the seller said it works anywhere in the world

  • John Brill Jul 26, 2008

    OK I will try the code in the settings menu tonite when I get home. It wouldnt just be that it needs unlocking would it. The phone says "service unavailanle" when I make a call. Thanks I will let u know.

    i also found this flash file on the internet.Would yhis help me?


  • John Brill Jul 27, 2008

    OK the restore (reset) did not fix the phone. The phone has a 3G in the top left corner where there is normally a signal strength indicator. When doing the manual lookup for networks it found claro amd TIM. Tim is the chip I have. But when I enter the number and click the connect in says "call ended". I may return to the USA to see my brother get married in August so I think I will sell it on ebay and get another. If you cant think of anything else to add I would like to say it was very kind of you to offer your help and... Thank You very much for your help, John

If this phone was made for usa region it will need software for your region as they may have flashed the phone befor sending it to you and only reinstalled the escential software for there region. You may not be able to get the software needed as this phone is an older model and lg themselves maynot be able to help you. Try emailing or calling your local lg phone representative and ask them if they can install the programs required but honestly it is probably cheaper to live and learn and just buy a phone from a local reputable dealer.

    Well the seller will tell you what you want to hear sometimes but I have delt with phones for 4 and a half years now and if you don't have software that you need it can be very hard to get if not impossible even for new phones. The phone you have we have had for a long while now and it maybe that lg can get you the software and install it to your phone but you would have to ring them and see, I know here in australia it would be almost imposible to get the software you need but if you can connect your phone to your pc and you don't need to have a card in it to do that sometimes you maybe able to update the software that you would require but I doubt it very much. With what you are missing I would say they have flashed the Phone to get rid of thier personal info, and have not reinstalled all the software given on the phone when bought new. Because if as new it would work anywhere in the world. You can try to do a master restore on the phone in the settings menu but this may not work. For a lg the code could be 1234, 0000,000000 if this won't work for you they have flashed the phone or changed the codes.If this was a nokia or samsung it would be much easier to fix the problem as the software required can't be removed even when flashed

Unlock Cingular LG CU500 for Cellular One

The LG CU500 is a 3G phone I think. You may need to change your SIM CARD to 3G. I had a razor and my Sim didn't work with the LG CU320 I bought. Also unlocking a LG phone is a little more troublesome that other phones. I found a solution on the web. sorry I don't remember the website address, but it comes up in any google search. Hope this helps.

Good luck
