I have the same problem on my unit:
Model Number: SAWEE10
Android version: 2.2_20110430
Kernel: 2.6.32.9
Build: FRF85B
I have formatted the SD, sized 4GB, using the tool suggested in first post, extracted the zip file in the root, in which i have firmware2 (2.7mb) and firmware-discovery(186.4mb, a zip file itself anyway).
I've shut down the unit, putted in the sd card, switched on but the standard android booted instead of the upgrading process.
I'm missing something?
Yes....the Build of FRF85B has nothing to do with it. Everyone has the same info in 'Build'. What is important is your Model Number of SAWEE10. This model is very different in physical build so the firmware is different to the DISCO models. The update method is very different too, putting the two firmware files (which are incorrect for your build anyway) onto a tf card won't work.
