[Guest Simon Jung]

I have the Xperia Z. Bootloader Unlock.

In the Last Weeks i have flashing the most Roms on XDA Lollipop Rom Marshmallow Roms. On Yesterday i have Flash the Xperia Firmware 228 and I can't edit my Sd card. I can't delete and copy my Files. I can't delete the Card with Phone. On Pc no Connect. Read Only.

Where comes my issue on Sdcard. Who can help me and have an Idea for me. Sorry for my English i hope you know me. SD Fix Tool not works nothing works. What I can is copy the Files on my Pc. But I can't delete on Phone and Formatting on PC. How can read write my Sdcard.
