It's been a while but I've found quite a few bits and bobs from my Esato days that I want rid of.
So for sale here is an SE Tool dongle. It allows you to flash, unlock, debrand SE phones and I think some others too. It's been a while since I was involved with all this but it still works. Will also allow you to download pretty much any firmware for a phone that you want. So you can change languages, branding anything really!
