Updating to Froyo

Here in South Africa we have a problem with Froyo updates for the Galaxy S.
Both the network operators and Samsung locally are now silent on all the issues.
With a “branded” firmware currently running on my phone I was left with to option but to “make ‘n plan”.

Below is the process that I used – obviously I will not accept any responsibility for any damage/bricking to your phone – but you are welcome to try it. So far I have tried on 2 phones with 100% success rate.

    1. Check CSC version.

  • This is done by “dialing” the following number: *2767*4387264636#
  • You will then know what version of firmware you are using: XFA or XFV or XFM etc.
    2. Set new market CSC

  • This is done by “dialing” the following number: *#272*[current 24 hour time]#
  • eg. At 19h55 you need to type in *#272*1955#
  • Then select XFA… device is wiped and set to XFA device settings.
    4. Download terminal app from Market

  • Open up the market and search for “terminal emulator”
    6. Terminal:

  • Open up the terminal that was downloaded in the previous steps and then run
  • su
  • chmod 777 /efs/nv_data.bin
  • mv nv_data.bin nv_data.bin.backup
  • mv nv_data.bin.md5 nv_data.bin.md5.backup
    7. Upload edited product code info

  • Use ADB.exe from the command prompt (in rar from Step4) to copy off nv_data.bin: adb push nv_data.bin /efs
    8. Terminal:

  • Open up the terminal that was downloaded in the previous steps and then run
  • su
  • chmod 755 /efs/nv_data.bin
  • chown radio.radio /efs/nv_data.bin (or chown 1001.1001 /efs/nv_data.bin)
    9. Check new CSC version.

  • This is done by “dialing” the following number: *2767*4387264636#
  • This should now say XFA
    10. KIES.

  • Plug in to PC and update using KIES
