Como Instalar a ROM Original da TX3 MINI Sem PC

In this video I show how to install the original system on the TX3 MINI. Many people take the TV box and install a modified system with false information, such as promising 32, 64, and even 512 gigabytes of internal memory, and in practice, it only has 16GB. My TV box came with a very buggy system, and it said it had 32GB of memory and 4GB of RAM, plus it came with a very buggy interface that sometimes caused the TV box not to start. Tired of this, I went looking for a method without a PC, and I didn't find one. So I decided to do it manually and test it, and it worked.
