If you find some issues in custom version, please ask your distributor for help.

2. Naming Rule of Common.cfg

You may feel confused about the common.cfg name When you use cfg files to auto provisioning.
Actually you can find the corresponding common name from Hardware version of phone except T3 Series.

Template of Common.cfg: y0000000000xx.cfg

(1) You must fill Ten Zero after y.
(2) xx means the first number strings of Hardware version

Take some examples for you:

T26G-Hardware is, then the common.cfg file name should be y000000000004.cfg

T46G-Hardware is, then the common.cfg file name should be y000000000028.cfg

T42G-Hardware is, then the common.cfg file name should be y000000000029.cfg.

W52P-Hardware of base is, then the common.cfg name should be y000000000025.cfg.

NOTE: The common.cfg of T38G and T32G is the same as phone model, y000000000038.cfg and y000000000032.cfg
