c975 operation band problem - GSM-Forum

Current operation bands in phone menu are 850/1900 and 3G.
If I update band 800/1900 via smart moto, network ok, but in phone menu values not changed. If I select one of phone's present band, I lost 800/1900 and dont swith back without box.
How to add 800/1900 selection in phone menu?

@ mail0,

Reset of the phone frequency is possible only if the handset hardware allows to do so. It might happen that the process of band changing was successfully completed but after switching the phone off and turning it back on, the band automatically changes to the default one. This means that phone’s hardware does not support customer settings.

No, no, after restart band ok, but if I change band by hand, I cannot restore previous. No ways for add or change operation band menu ?
