1. First find the model number and downlaod a firmware of yoru choice from the support area. For example we will choose ALCATEL 5033 model and we will get 5033X-2[X=G]OBGB2_7L7KCSK0.osp firmware from the support.

2. Before flashing it we will use 'Change CU refference' option from OTSmart and we will set the new provider id to match the firmware we plan to flash. In our example we will set it to 5033X-2GOBGB2  (simply remove [X= , ] and part staring _ from the filename to obtain the value)

3. Now flash the downloaded firmware

4. Enjoy !
