[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] eChino:
1) Partition is ext4 (according to recovery)

2) Tried TWRP 3.3.1, 3.2.1 and 3.1.1, same result

3) Haven't changed anything

Any other guess?? I'm kinda stuck on this issue :/

Edit: Found some lines in the log,but I have no clue about code... Is that something?
