    • Recommend use v1724 for FACTORY FW flashing, v18xx line for Infinity FW Flash Read and Write
  2. [NAND on MT6570] In some cases "stuck on logo" devices can be fixed only via FFU (whole flash) format!
  3. [MEMORY TOOL] Partitions state on MEMORY TOOL will be empty in MT6570 NAND phones, it is normal behaviour and can not be fixed.
    1. Read-Write data, which you want, ignore "EMPTY" states.
  4. ADL checksum MAY NOT WORK CORRECT on MT6570 NAND devices! Result - stuck after system/userdata partition flashing
  5. FileSystem flashing on some SBC-enabled devices ( except SYSTEM/CACHE/USER ) may fail! Solution - exclude them from flashing list.
  6. Cheap MT6739 devices require BATTERY REMOVING after EVERY operation in most cases!
  7. Meizu support is limited by Preloader Level ( No BROM SLA ) - you must UNTICK "PMT Update" and "PRELOADER" partition from flashing list!
  8. [NAND on MT6570] In some cases device MAY DEAD after flashing! Make sure you have TESTED firmware version!
If you have download FW from internet/other source - make sure it preloader CONTAIN 3 EMI record! Preloader jc45btlc with 2 records KILL SOME DEVICE TO UNRECOVERABLE STATE!!!
