I have a Xiaomi Redmi 9 phone, and in case of this device I use a custom ROM - crDroid. From time to time, I update the phone's firmware by downloading a corresponding firmware package from xiaomifirmwareupdater.com .
When you look inside the firmware package, you can see the following content:
Path = fw_lancelot_miui_LANCELOTEEAGlobal_V12.5.4.0.RJCEUXM_67a1671939_11.0.zip
Type = zip
Physical Size = 40808894
Date Time Attr Size Compressed Name

So I have the following questions:
1. Will the preloader be touched in any way when I flash this zip via TWRP/SHRP recovery?
2. What's the difference between
preloader_raw.img , preloader_ufs.img and preloader_emmc.img ?
3. In the fastboot ROMs there's preloader_lancelot.bin which (according to the scatter.txt file) goes to:
> partition_index: SYS0
> partition_name: preloader
> file_name: preloader_lancelot.bin
> is_download: true
> type: SV5_BL_BIN
> linear_start_addr: 0x0
> physical_start_addr: 0x0
> partition_size: 0x80000
> region: EMMC_BOOT1_BOOT2
> storage: HW_STORAGE_EMMC
> boundary_check: true
> is_reserved: false
> operation_type: BOOTLOADERS
> is_upgradable: true
> empty_boot_needed: false
> combo_partsize_check: false
> reserve: 0x00
Is this preloader_lancelot.bin file related anyhow to preloader_raw.img, preloader_ufs.img or preloader_emmc.img ?
