Tried the latest release today on my mini pro (mango), but just using an old class 4 8GB card (tested before, 100% flawless), that isn't a huge loss in case the card gets damaged. Formatted as FAT32 using SDFormatter. Have done full factory reset, wiped system and cache, rebooted into recovery, flashed cm-13.0-20160418-UNOFFICIAL-LegacyXperia-mango.zip and MDPI_miniGAPPS-6.0-20160419-tb-signed.zip...
But after first boot, I imediately got the message "Music was closed", followed by "Trebuchet was closed", and this comes again and again directly 1 second after clicking "ok". Tried to reboot 2 times, but "Trebuchet was closed" always shows up again, I can't use the ROM at all...
