Galaxy S Froyo Firmware Upgrade


I was getting increasingly annoyed over the slowness of the Froyo release for the Galaxy S in the UK.

Samsung had started rolling it out in other parts of Europe, so there had to be a way of getting it!

A quick Google brought me to the following page:

You need a PC and the Samsung KIES software:

This worked fine on my UK T-Mobile Galaxy S (GT-I9000)
(Do not blame me if you brick it! You have been warned!)

Follow the steps below to install Android 2.2 Froyo on your Galaxy S:

Start up kies and connect your phone. Wait till kies recognizes the sgs.

Go to firmware upgrade.

If it doesn’t report a JPM/JP6 upgrade close the upgrade window but do not close kies!

Go to windows start > run > and type “regedit”

Navigate to HKEY_CURRENT_USER/Software/Samsung/Kies/DeviceDB/

You will probably see a bunch of numbered keys (they look like folders) Find the key/folder that has strings that match your current firmware. So if you are on JPK look for that in the keys. If you have more than one galaxy S (it can happen) then match the imei with the phone you want to upgrade.

Change the following values so they look like this:


No go back to kies and click on firmware upgrade again. You should now see the JPM upgrade.

Feel free to post any comments to this post. So far flash support is ok. Maybe a bit slow.

    Update: Almost 24 hours has passed since the firmware upgrade. Overall the phone does feel slightly quicker. Also there are some great new features. Now apps can be stored on the SD card, its also possible to apply ALL updates at once in the market. The new Gmail App is much better, although handling multiple labels is still tiresome.
