9 GRT Software: Regular Usage
Step 1: Select the section SWUpdate
Step 2: Choose the area you want to work with
•Personal Repair
Personal Repair is always accessible. Basis for the decision if a SW-Update is
authorised by BenQ Mobile is the so called Service Release-Table .
Example: Mobile Phone has already SW50. Service -Release-Table shows SW50
In this case SW-Update is not necessary and therefore not authorised
In any case customer data can be erased on request. (xfs and mapping have to be
activated) Of course JPICS hardware and authorisation have to be available.
•Operator SWAP
This area is only accessible if you are released by the service management to
perform SW-Updates for Net-Operators. Basis for the decision if a SW-Update is
authorised by BenQ Mobile is the so called Master-Table .
Customer data will be erased without any exception and any chance to influence by
the user. JPICS hardware and authorisation have to be available.
•Operator SWUpdate
This area is only accessible if you are released by the service management to
perform SW-Updates for Net-Operators. Basis for the decision if a SW-Update is
authorised by BenQ Mobile is the so called Master-Table .
Like in “Personal Repair” customer data can be erased on request. (xfs and mapping
have to be activated) Of course JPICS hardware and authorisation have to be
available.
