Maria searched online: “Nokia C2 TA-1204 factory reset tool.”
The phone worked perfectly again. And the folder labeled “Nokia C2 Reset Tools” on her PC? Deleted — except for MTK Client, just in case.
However, she found a niche utility: (an open-source Python tool). Unlike SP Flash Tool, MTK Client could connect to the phone in BROM mode (preloader) without shorting test points on many MediaTek devices, including the TA-1204.
