Hi Team,
I am working on a Vivo Y04 and trying to flash/repair it using UFI eMMC ToolBox (v1.8.0.3246) via ISP (Direct eMMC).
The box successfully identifies the eMMC (SK Hynix X0H128), but it cannot detect any partitions. The "Partition type" shows as "Unknown" and the partition list remains empty.
