Known issues/warnings/info:
1. [NAND on MT6570] v1712, v1736 loader packages NOT SHOULD BE USED! Since they 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!
1. [NAND on MT6570] UBI SPARSE image flashing may take MUCH time (up to 5 minutes and more) for some devices!
3. [MEMORY TOOL] Partitions state on MEMORY TOOL will be empty in MT6570 NAND phones, it is normal and cannot be fixed.
Read-write data, which you want, ignore "EMPTY" states.
4. [MEMORY TOOL] Old protocol secure devices (MT6750/MT6755) - LeEco and similar
In some cases WIPE partition may not work!
5. ADL checksum MAY NOT WORK CORRECT on MT6570 NAND/eMMC devices! Result - stuck after system/userdata partition flashing
