  14. This is the correct way to install a Rom to make it work, first you have to have v20? Installed and phone rooted make back up, i used Rom Manager get it from market really easy to use. When you have done all this follow these instructions exactly.

    Reboot Into Recovery and wipe Cache
    Then Wipe/Data/factory Reset
    And finally go to mounts and Storage-> Format System
    Now come back and Say Install Zip from SDCARD
    Choose the Zip
    IT will do the update and say Process Complete
    Then go back to Reboot Your Phone

    this is the correct way to get zipped versions of 2.3.4 or 2.3.7 working

  15. ok now my gsm not working cannot get my sim to work no network or signal

  17. anyone who cant get phone working again you will have to reinstall the original firmware using, pc usb lead and phone + KDZ updater software, i really wanted a flash of 2.3.4 to use KDZ but none around. i dont think all phones can be updated because of the phone shop who sold you the phone like carphone warehouse they have locked codes built in that you cant get rid of? i can only put v20e or v20b on my lgp500 none of the others work dont know why.
