I read that but didn't test it: https://forums.oneplus.net/threads/...-without-losing-internal-storage-data.439999/please how can I format data partition of my zuk z1 in f2fs? I tried everything with varoius twrp version: twrp-3.0.2-0-Z1, TWRP-3.0.2-ham and other; but after formatting, twrp doesn't recognize data partition that is 0 MB large and it is impossible to mount. Please help me. Thanks
