How to download official ROM updates for your LG mobile phone

  1. Find your LG mobile phone's Model and Serial Number. e.g. My phone model is P690F and its S/N is 123ABCD123456(it is labeled under battery).
  2. Type the following address in your web browser's url field:
    http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?model=[model]&esn=[serial_number]
    replace the [model] and [serial_number] with your LG phone's model and serial number.
  3. Type return to load the page. It should returns a string. You need to view the page source:
    • On Firefox: Tools -> Web Developer -> Page Source (Ctrl+U or Command+U)
    • On Safari: Right click blank area in the page, select View Source in the context menu
    • On IE: View -> Source
  4. Find the number inside <ESN></ESN> tag
  5. Type the following address in your web browser's url field:
    http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=[esn_number]
    substitute the [esn_number] with the ESN number we get from last step.
  6. Load the page (it is a blank page in web browser), you need to view page source, you can then see the ROM update url inside <sw_url></sw_url> tag.

      The page is blank, you need to view page source to find the sw_url.
