In this tutorial you will see how to flash lg cookie with new firmware. 1.) BACKUP - First off all you should make a backup of your phone files (contacts, messages ...) because after flashing, all the files saved on the phone will be erased. I recommend that you use LG PC SuiteII. - Dont forget to unplug your phone. 2.)DOWNLOAD GSMULTI AND FIRMWARE FIRMWARE LG KP500 KP500AT-00-V10n-DEC-17-2008 (v10N) NEW! <Bạn vui lòng đăng nhập hoặc đăng ký để xem được nội dung này!> FLASHER LG - MultiGSM ver 3.0 + kp500 .dll file <Bạn vui lòng đăng nhập hoặc đăng ký để xem được nội dung này!> 3.)INSTALL THE SOFTWARE AND DRIVERS - DRIVERS WORKS ONLY ON XP WINDOWS (Don't connect your phone on computer yet) Downloaded files should be un-ziped (I unziped them in one folder which i made it on desktop) You got next files: program - SETUP_GSMULTI_V30 - KP500_081002.dll firmware - KP500AT-00-V10n-CIS-XXX-DEC-17-2008 - KP500AT-00-V10n-CIS-XXX-DEC-17-2008.bin.mbn 3.1.) Install GSMULTI (SETUP_GSMULTI_V30). The icon will shows on your desktop otherwise the program install on C disk, folder GSMULTI - start GSMULTI - select: Settings/Configuration - put .dll file and firmware file in and choose USB then click OK and close program 3.2.)Install DRIVERS (INFINEON and TI_NEPTUNE) Drivers to be found in install folder of GSMMULTI program. My path is C:\GSMULTI\UsbDrivers - First install INFINEON - Second TI_NEPTUNE 4.) PREPARE AND CONNECT YOUR PHONE - Now u take a phone (shut it down) and remove, BATTERY, SIM CARD and MEMORY CARD then - conect it with your USB cable to computer (I suggest that u connect only in one USB port on computer) - wait about one minute that comuputer recognize new device 5.) USBMap PROGRAM - Run program USBMap_V01 (which can be found in C:\GSMULTI) - Select INFINEON and then click MAPPING START -WAIT (about one minute) that USBMAP will find USB port where is the phone connected - When the port will be found click on (select it) and press SAVE&EXIT 6.)MAIN PART - FLASHING - Run GSMULTI program (shourtcut is in your desktop) - Check if settings/configuration are the same like we set it before (otherwise look step 3.1.) - Now its everything ready to start flashing - Check MODEL and SW VERSION and if that is correct just click START and wait until the program finished - And voila, here we have a new firmware version That's it.
