>then flash into your GTA0x GSM modem Wait, it works both on gta-02 and gta-04?
Also, did you test if data connection works? I don't use phone calls, only encrypted ssl over tcp over 3g/wifi. I am very interested if this can be flashed to gta-02 device, (unfortunately I don't own gta-04). Also, is there is a possibility to change IMEI during flashing? Sorry if my questions are a little bit off topic. Anyway I am very interested in free fw for my devices - OM gta-02 and n900. 10/13/13 06:08 -ում, Michael Spacefalcon-ը գրել է: > Hello Om community, > > I am very pleased to announce that after many years of searching, I > have finally found a copy of TI's firmware deliverable package for > their Leonardo development board, i.e., for their Calypso/Iota/Rita > chipset reference platform.
