[Redmi Note 8 Pro Questions & Answers] MarkLev:
I understand what you're saying now. I found these 2 pgpt and sgpt partitions in scatter file, which have "file_name" as "NONE". pgpt with the second index-SYS1 (after SYS0) and sgpt with the last index-SYS49. Both have EMMC and UFS Layout Setting:

I also found someone with similar issue here. Unfortunately, no one answered him on that post.

Can you explain what the commands do?

I guess, gpt.img is a backup file you have on your PC, /w for /write, what about /s1 and /s-33 and /c33?

How to differentiate between EMMC layout and UFS layout when flashing?
