Hi 0xinit69, @0xinit69 said in Installation fails on Redmi Note 9 (merlin): BTW, do i flash that zip file via TWRP? Sorry I'm a noob at mobile linux. What does this do? I never understood. When a port is made from a device for the first time, flashing the device is more complicated and time-consuming, which is why we often use the useful TWRP tool. When the device is later added to the UT Installer, it takes over the necessary tasks that were previously performed by the TWRP tool. Greetings Mario
