Today, I saw my grandfather's previous mobile phone, Hongmi 4A. The hardware is OK, but the system is no longer updated. Then the salted fish is 50 yuan. I want to brush the machine. Here I declare that it failed. I don't know why rec reported a pile of errors and didn't continue to study. The article is only for records.
Go to XDA to see what you have before brushing the machine:

Brushing steps
Before brushing the machine, I need to unlock BL lock and write a TWRP. I don't know if there is BL lock
https://twrp.me/xiaomi/xiaomiredmi4a.html
There is something to see here
You need to plug in your mobile phone card
http://www.miui.com/unlock/index.html
Unlocking tools also need to be installed
Binding number
Open the unlock
Open under fastboot
Unlock
ok
success
Let's see if it's on the device link first
Well, we're going to start working
Xiaomi opens the MTP and puts the brush bag away
Look at the connection first
Restart to fastboot
Confirm the connection
Brush rec
Because there is no disk in the rec above, this is a side push
Enter rec
twrp picture
Advanced delete
adb reboot bootloader
Restart to fastboot
fastboot reboot
fastboot restart
fastboot flash recovery .\twrp-3.3.1-0-rolex.img
Brush img file
fastboot reboot
fastboot restart
su dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery
This is written into the mobile phone by putting twrp in the root directory
The brush system is gone!!!
Hum hum, start saving bricks...
Make sure it's my lock

Copy this to the tool
start ε= (´ ο｀*))) Oh, I turned the car over again Brush the machine. It comes and goes like the wind.
The mobile phone is restarting. Let's reflect on why... BL solution, brush twrp, I don't know
Really ill fated
I studied it for a while. It's estimated that it's the pot of twrp. How old am I (I have to roll over)

Note here that the machine is locked, so unlock it again
Because it's locked
Turn off the mobile phone completely. Press and hold the volume with both hands of the start button. Do not release it. After the mobile phone vibrates, release the start button Press the key and enter the recovery mode without letting go of the volume
Here we must remember to let go after shaking...
Unzip the compressed package
Install it. It's still the same
