There are several different ROMs to choose from, however we recommended installing the ROM in the guide below. It is based on an official Android 2.3.5 ROM with all carrier branding and bloatware removed - in other words, the ROM aims to provide a pure Google Android experience without any Orange branded software. If you wish to install another ROM, you can see a full list of all ROMs for the Orange San Francisco II here.

  29. Troubleshooting

    If your ROM fails to install for whatever reason, it is likely that the zip file is corrupted or did not download properly. Do not worry, your phone is not bricked. You need to remove the microSD card from your phone (it’s next to the SIM card and battery). Obviously, you will not be able to use your phone to transfer files to your microSD card, so you need to get another phone that has a microSD slot or buy a microSD to USB Reader from eBay (they only cost around £1). Then you need to delete the old ROM zip file, redownload the ROM zip file and copy it to your microSD card again, and follow from Step 9 on this page.

  30. Wait for the ROM to finish installing. This may take up to 10 minutes.
  31. Press the Back button and highlight and select reboot system now.
  32. Your phone should now boot into your new custom ROM. It may take up to 10 minutes to boot on your first go, so be patient.

    Troubleshooting

    If you are stuck for longer than 10 minutes, don’t worry; you haven’t bricked your phone. Follow from Step 9 on this page again.

    If you get the same problem again, you need to remove the microSD card from your phone (it’s next to the SIM card and battery). Obviously, you will not be able to use your phone to transfer files to your microSD card, so you need to find another phone that has a microSD slot or buy a microSD to USB Reader from eBay (they only cost around £1). Then you need to delete the old ROM zip file, redownload the ROM zip file and copy it to your microSD card again, and follow from Step 9 on this page. Make sure you leave your computer unattended when downloading this time, to avoid corruption.

  33. Congratulations! You have debanded / installed a custom ROM on your Orange San Francisco II. If you wish, you can delete any files you have downloaded in this guide, including the ROM zip file.
