i just bought the Nexto OTG ND2300 and it comes with v1.03 amd then i tried to upgrade the firmware to firmware V1.21 and OTG Xpress V1.03
i tried to upgrade both because they don't work both.
for the v1.21, when i finish upgrading, and the LCD of the nexto just show the Nexto v.1.21 and can't go anything except turn it off.
for the OTG Xpress V1.03, when i finish upgrading, it just show that Nexto Xpress V1.03 and also can't do or press anything.. i can't browse anything
finally i want to use the version that i got at the first time when i got my Nexto.. so i tried to reset it by turn nexto on and then press reset, but everytime when i press the reset buttom, the Nexto will turn it off automatically..
