Known issues/warnings/info:
1. [NAND on MT6570] v1712, v1736 loader packages SHOULD NOT BE USED due to these packages have ftl/ecc errors!
In result you will give read/write FW errors and rest problems at all.
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.
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 BE 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 !
Preloader info shown now during FW load.
