  1. Hi,
    I had problems getting the LG PC suite to connect to the phone. Clicked on “Settings”, “Sd card & phone storage”.
    Item at the top of the list is “USB Connection mode” “Mass storage only”. Make sure this is NOT ticked.
    Worked for me on two phones

  2. Hi everybody,
    If anyone wants to upgrade Ver: Android 2.1 Eclair in LG GT540 Optmius.

    Wolverine Mobiles
    +91 9994858580.

  3. I am happy with 1.6 ver : ), Who says it doesn’t work?

  4. In android 1.6, there is a group contact. Why is it that ihe 2.1 update has no group contact? Also, in the 2.1, it has no send Vcard? these features are basic even in low end Nokia phone.

  5. Remember upgrade is available for the GT540 but not the GT540GO

  6. You have to wait for sometime after u connect ur usb.. it will automatically connect ur mobile phone then u have to start update.. but first u have to take out ur sim and memory care. Bets of Luck

  7. When I tried to plug my phone into the computer, LG mobile support tool does not recognize the phone so I am not able to update it, I have tried turning the Mass Storage Device button off and have installed the USB driver but still nothing is working. Have tried taking the sim card and memory card out and still the program does not recognize my LG Optimus GT540. Please help as I want to update to Android version 2.1 :(

  8. I finally 2.1ed it :) after i unticked the “mass storage only” on the phone setting so i was able to upgrade the drivers
    it all make what it promise; easy to msg just a click from contacts link, multi-applicate and smooth in menus with long life battery it is almost doubled
    but i have a problem i dunno how I make it 7 home-screen cuz the quick link on the home screen menu “add home screen” was disapperad
    how i make it 7 home screen?

  9. A few friends also still had probs after i explained how to update to 2.1, but after they reinstalled all the drivers etc and being little patient (and wv a little bit of my help ) theyve also now managed to finally update to 2.1…so there is still a bit of hope for other ppl
    I have been onto LG about this problem (and how much trouble its also causing other ppl )via email, and i yet to recieve an email back ???? (ive been now waiting for over 10 days for a reply now……perhaps i should learn how to speek taiwanese while i wait !!!!!!!)
    I will never ever buy another LG mobile phone again, customer care is the lowest, if there is such a thing……..and in my mind LG stands for one thing….. Low Grade. and i wouldnt used another even if they gave it to me for free !

    after upgrade of android 1.6 to 2.1 in my lg gt540 i am unable to send anything via bluetooth but i can receive file frm others.

  14. I have been trying to upgrade since November, just says ..”phone is up to date” (Android 1.6)….
    however, yesterday (10th Jan) update to Android 2.1 happened. This was latest update for OPTUS

    The 2.1 system is quicker and seems to use less battery power, however I’m having a couple of strange problems now. When I turn on the phone there is no longer any Android logo, just blank dark screen, and I have to press home button a few times before the main screen opens.

    When it is in idle it keeps making noises and saying “preparing sd card’, although I can access and use sd card already? Any ideas why this may be happening?

    • with 2.1 s/w you need a higher speed SD card – at least class 6 .

      I got a class 10 from ebay – works without preparing error

  15. its not working guys
    it keep saying u have already the last version but its not
    i guess LG software has bugs

  16. Have tried to update my gt540 many times. i get to the download stage, and it doesn;t download anything. it says that there is a problem with my internet connection, even though i have turned off my firewall, and it is fast broadband. I have also disabled my modem which was recommended in another website. Have emailed lg for advice but no help so far. Unless they create an .exe to use i’m just gonna give up!! Wish i had purchased another brand of phone!!

  17. i followed everyting and downloaded it all……..then it said you already have the latest update….please help……i really want android 2.1

  18. This update thing is quite tiring, its only saying that “The Cell phone is the latest version already. So you don’t need to update.” and i cant even click “Start Updating” so som1 pleaseeeeee help me pleaseeeeeeeeeeee

  19. Update went really smoothly, not sure that I notice much difference in the two versions of Android though since a lot of the features missing in 1.6 had been added by LG anyway. I do have 1 very severe problem though.

    I backed up my contacts as recommended and restored them after the upgrade, however depsite the fact that PC Suite states restore successful when I browse my contacts there are none. Never mind I thought, the contacts are synchronised with Outlook anyway, so I completed a sync contacts which worked as expected with a lot of additions required for the phone, sync went ahead and completed successfully, however there are still no contacts on my phone. Have I missed something obvious?

  20. Does anybody know why my phone connected to the update ive dlwnloaded the thknvs and nothing happens wen i lut in mu usb

  21. Hi, I was upgrading mz GT540 and in the middle it said error program not responding. now Im freezed and stupid LG tool says version updated 20B but phone does not work at all as after starting and showing ANDROID logo it stopps and gives me error system not responding. I§m fed up of trying everyithing. does anyone knows how to help me plsssss

  22. my gt540 will not connect to computer if any body can direct me to a
    driver that works, would be nice,all driver downloads ive tride do not work or it may be the phone very dissapointed as i wanted the new OS.

      • Hi Sanath, I have seen that the touch response was lost who ever upgraded it from 1.6 to 2.1. How about you? Are you facing the same problem? Can you install the software on the SD card after the upgrade?
