It didnt worked to me. Im new on this of flashing cellphones. I dont know exactly when im installing a raw image to my cellphone if it is validated by the vendor or who is the creator. I need to flash my cellphone since the bootloader crashed from one day to other without explanation. Before the cellphone was working perfect. Now the gps is not working at all. Currently i will flash again with another raw file and lets see how it goes. By the way. The raw file i used before and gps is not working is the WW_ZE550ML_4.21.40.311_20170609 Now trying with the WW_ZE550ML_2.20.40.156_20160815_new
