hello, my d4 has 64 gb card with fat32 partition. until recently i had no problem flashing zip files from my sdcard-ext with safestrap 3.05. now it doesnt mount. i upgraded to safestrap 3.11 but nothing changed. any advice? thank you. Update: using a card reader, i moved all data from card to pc and then formatted the card on PHONE. then moved all data back to card. now its working fine.
