Try downloading the file again from a PC and copying it directly into memory from TWRP.
Have you done some kind of Formatting before trying to install the ROM?
When you select install from TWRP and choose the Download folder, it doesn't appear? If you can, try moving the file from the Download folder to main memory.
Hello, would you tell me if there is an official version of TWRP for the xiaomi mi 10 lite 5g? I searched for it on your website but I can't find it.
Thank you so much
