The default for USB disk is fat32

php editor Yuzai tells you that the default format of the U disk is FAT32. FAT32 is a common file system format that is widely used on various storage devices, including USB flash drives. It has good compatibility, easy operation, and is suitable for multiple operating systems. Using the FAT32 format can ensure that the USB flash drive can read and write data normally on different devices, which is convenient and practical. However, it should be noted that the FAT32 file system has some restrictions, such as the maximum size of a single file is 4GB, so when using a USB flash drive to store large files, you need to choose a suitable file system format.

There are many types of USB flash drives on the market now, with rich capacities, such as 8G, 16G, 32G, 64G, 128G and so on. These capacity types are relatively common. However, not all USB drives can be used to flash the box. Generally speaking, 8G or 16G USB flash drives are more commonly used when flashing. Theoretically, 32G and 64G USB flash drives can also be used. However, some set-top boxes may not support large-capacity USB flash drives. When you insert a large-capacity USB flash drive, it may not be recognized and its contents cannot be read. So please make sure that your set-top box supports the capacity of the USB drive you are using.

I don’t know if you have noticed that there are three common file system formats for USB flash drives, FAT32 (default), NTFS, and exFAT formats. All three formats are acceptable when storing data, but when using a USB flash drive to flash a computer, you need to use the NTFS format, and when flashing a set-top box, use the FAT32 (default) format. Some USB flash drives are made into system disks, so the default file system format of the USB flash drive is not FAT32. Another point is that the USB flash drive must be in one partition. If you don’t understand USB flash drive partitions, you may have a better understanding of computer hard disk partitions. Computers generally divide storage into C drive, D drive, E drive, F drive, etc. Similarly, a USB flash drive can also be partitioned in this way. Therefore, the flash drive must be in one partition.

Here’s the point to know:

①The USB flash drive must be formatted before flashing. The format is FAT32. The allocation unit can be 4096 or 8192 bytes.

②The USB flash drive must have one partition.

③ Put the four files named bootargs.bin, fastboot.bin recovery.ing update.zip and other formats into the USB flash drive or just the update.zip file. Remember that the update.zip file does not need to be decompressed.

④Insert the USB flash drive into the USB port near the network cable port.

⑤Enter the flash mode to automatically flash the phone or select the option to update in English which is "Update from external storage".

Remember, the first three are the most important.
