I have two TG800, and the problem is one of them don't recognize the SIM of CLARO. In Trunk Status say:
The TG800 work's fine have the firmware 188.8.131.52, and the TG800 with the problem have the firmware 184.108.40.206.
Claro use the frecuency PCS1900
Can anyone help me, or give me the firmware 220.127.116.11 for a downgrade.
