C3520 Flash Loader 7.5 4 CSC V0.2 Citrus Lite
A lot of devices require a custom firmware to be flashed in order to work properly, but because the C3520 is an older device, it does not need any custom firmware. Installing one of these firmwares can be very harmful for your device and will cause many problems when trying to update the phone's software. The easier option would be to use Flash Loader 7.5 4 CSR v0.2 Citrus Lite which is free, efficient and safe in order to install all necessary updates without causing any harm to your phone in the process!
