How to recover data from Xiaomi?

Question

Data recovery

The essence of the problem is as follows: on my xiaomi note 4x phone there is a video recording of the violation, it will be a huge plus in court, but it has a 4-digit pin, I don’t remember it at all, when connected to a PC, the phone is defined as music. the player and files are not displayed.
Are there any options for solving the problem, counting in any way (soldering to contacts, special software for a PC to display the file system of the phone), everything is on the phone - starting from the box, checks, etc.
There is also all the data from the Mi account, just checked

Answer 1

1. If the phone made a backup on Mi Cloud - look there.
2. If the phone has an unlocked bootloader, root and twrp - install software for twrp, make a backup using twrp, open it with r-studio, like an external drive - merge the data.
3. If a phone with a locked bootloader is the last chance, try to remove an image from the phone with a programmer - Mtr Tool, Infinity.
4. The most ideal option is to remove your PIN code (which is software) with a programmer.
Most service centers have such programmers (removes the lock (pin code), without resetting the phone.
