However, as soon as I reboot the system after transferring any app, second partition can't be mounted and I have no idea why is it happening.
I've tried ext2/3/4 with the exactly same results.
System mounts second partition without a problem until I put something on it, and then it won't do it again.
I've formatted the card using Partition Wizard, Recovery (TWRP 188.8.131.52), manually (adb shell) and nothing seems to make a difference.
The partition is still there (fdisk sees it) I just can't mount it.
If I run e2fsck on the ext partition (with -y) it just goes into infinite loop *inode error*
I did a surface test of the card but there are no errors present.
OS is FusionX (JB 4.1), phone Huawei Ascend G330.
Any help is appreciated!
