EE Upgrade Step 1

Step 1: check this Cel-Fi can be updated

Only Cel-Fi RS2 devices supplied directly by Orange, T-Mobile or EE in the UK or from one of their directly-supplied dealers, or from the UK distributor, Frequency Telecom ( for the Orange/T-Mobile/EE networks can be updated using this process.

Devices supplied to or for other networks, either in the UK or elsewhere, cannot be updated via this process - if you try, you will receive no update options.

If you have an old white Cel-Fi RS2 with a micro-SD card inserted in the base of the Window Unit (for T-Mobile or Orange) you must remove and discard the memory card before doing this update. If you do not remove this memory card first, then the update will fail and the device will become unusable.
