You will have a totally blank Internal SD Card that will have no Operating System, and the card will have to be partitioned with a file allocation table before the operating system can be restored!
Unless you know how to set up partitions and give them their sizes and to format them, you are totally screwed,
, and you will have to recover
your phone.If you select the setting format emmc and you have an external SD card installed, it may wipe and format this card by default as it may recognize this card as the default storage so if you don't want to lose all the data on your external SD card by mistake, then remove it.
EMMC stands for Embedded Multi Media Card, and not external memory card like some people believe, its the built in SD card, that's built into the electronic circuit board on your phone, its embedded.
Its split into partitions, in order to give the operating system its own space to boot, hold and execute its system files.
The FAT boot method is the same process as MMC/SD Configuration flashing and booting procedures, which are not embedded like your external SD card or the type you would insert in your portable camera.
The EMMC/SD card must be formatted with the correct partitions prior to flashing any device. Once the EMMC/SD is configured it will contain two separate partitions that will be used to boot the device.
The FAT32 partition is used for uboot, xloader and kernel. The ext3 partition is used for the actual file system. Once both of these are loaded onto an EMMC/SD the device can boot up and run the selected file system.
The EMMC is an Embedded device. So we have to partition and format the EMMC using a kernel utility like (fdisk, mke2fs) and what's available in the File System.
So there you have it my friends, LEAVE well alone
this is an administrative setting and only for advanced users, not for Joe bloggs!!King Wasabi
