twrp-3.6.0_9-0-n8000.img.tar is a custom recovery image designed specifically for the Samsung Galaxy Note 10.1 (GT-N8000)
The string twrp36090n8000imgtar top is likely a jumbled or typo-heavy version of specific file commands used to install Team Win Recovery Project (TWRP) on a Samsung phone.
If you'd like, tell me the exact model number (e.g., SM-T290, SM-T295, SM-T295N) and whether you have a .tar or .img file and I will give precise files and exact button combos for that model.
