This is the trickiest part. There are dozens of versions (v2.5.xx, v2.5.xx_v4, v2.5.xx_v6, etc.). The best source is (the archive for flash drive technicians) or flashboot.ru .
: Re-identifying the true capacity of the drive if it has been incorrectly reported. Configuration Tuning
The Dual Density mode is critical: the controller uses part of the NAND as SLC (high endurance, fast writes) as a write cache, later folding data into TLC/MLC space. MPTool controls the size of this SLC cache.
| Code | Meaning | Remedy | |------|---------|--------| | 0x01 | NAND not supported | Update DBF or wrong chip | | 0x03 | Bad block table corruption | Run low-level erase | | 0x0F | ISP download failed | Short data pins (hardware reset) | | 0x28 | Capacity mismatch | Adjust SLC/TLC ratio |
⭐⭐⭐⭐ (4/5) – Essential for repair, frustrating for beginners.
