If you are working on a Spreadtrum SC7715 device, you know the pain. Unlike Qualcomm or MediaTek, writing a lost IMEI back to these budget chipsets often requires specific "factory" or "engineering" tools.
After the 2021 security patches, many old tools stopped working. Here are the top 5 latest tools (as of 2021) that still support the SC7715 baseband.
While originally for MTK, the 2021 modified community builds have added a "Spreadtrum Bridge." The v10.2108 build specifically lists SC7715 in its config file.
For the average repair technician in 2021, UniTool (2021.09) is the winner. It handles the new security patches, has a clean UI, and doesn't require expensive hardware boxes.
