Rooting Redmi Note 5 and Note 7 Pro
11 April 2019
For those Redmi smartphone users, you might have searched queries like “Redmi Note 5 how to root with anti rollback check” before. Look no further, here’s a simplified tutorial of it.
Or proceed here, if you prefer a longer and more detailed tutorial.
Use Case: I dropped and cracked my Redmi Note 5 screen and bought Redmi Note 7 Pro to replace it.
Therefore I wanted to use Titanium to back up and restore my files because it was the most comprehensive (or exhaustive?) backup app ever. However, it requires a rooted device - I proceed to root and back up all the desired files, contacts, messages etc.
When I tried to root Redmi Note 7 Pro, it told me to wait for 360 hours (or 15 days) before Xiaomi allows me to unlock bootloader. I’ve read that the waiting time varies from 72 hours to 720 hours. What /r/Xiaomi said:
The waiting time on models manufactured before 2018 is 72 hours. On models manufactured in July 2018 or later, it is 720 hours. Currently there’s no known way to bypass the waiting time.
Eventually I decided on using Mi Mover to transfer files over Wifi. Some apps weren’t transferred over, and the contacts and messages required multiple transfers… but it was quite reliable.
