...seems to have inside battery for ME75 phones (EBA-770). SXG phones use EBA-750 battery type. If you upgrade firmware to hight, automatically appeair message from attachemment. You have thre options:
- make jumper between Ident and (-) pin (see in attachemment)
-replace battery with EBA-750 type
-downgrade firmware in your phone.
BTW: SXG75 is the ODM phones (Qualcom) not S-Gold phone...
