| I believe sigma box is the best because it deals with ******** CPU unlocking and network repairs. MTK and SPD don't really need a box for flashing. SPtool is the best tool for flashing and FRP removal by code (format manual). MAUI META does the trick when it comes to nvram and imei repairs. SPD best flash tool UPGRADE RESEARCH TOOL, WriteImei tool is the best tool to repair imei. I guess my main point is that SIGMA BOX does the hard tasks which pays more than just working on a MTK or SPD chip. |
