SP Flash Tool is a tool for MediaTek devices that may be used to reflash the device’s firmware, should anything go wrong with the device’s software.
While it is a very versatile and useful tool, it has an unsafe mode called “Format All + Download”, which may be damaging when used by a consumer. This mode erases your entire flash storage before flashing the firmware, which makes the device lose serials such as MAC Addresses and IMEIs, lose keyboxes used for DRM and several radio calibration parameters. These fields are programmed at the production-line and cannot be reprogrammed by the end-user.
To prevent this, we are sharing a patched copy of SP Flash Tool that does not have this option at all. Hopefully, this should help you to restore your device with confidence
