    Install method explained


    Since the install steps provided on OP maybe confusing I thought on sharing here the steps I've made in order to get TWRP working....let's call it a "noob friendly guide", ok?

    Here he we go:

    0 - Your bootloader must be unlocked. If it's not, then follow step 1 of the instructions provided HERE.
    1 - Download both twrp-3.3.1-15-laurel_sprout-mauronofrio.img and twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip files present on OP
    2 - Download latest Magisk Installer, Magisk Uninstaller and Magisk Manager from HERE.
    3 - Copy all of the above to your phone internal memory (since current TWRP doesn't allow sdcard nor USB OTG yet...)
    4 - Connect the phone to your PC
    5 - Reboot to bootloader
    adb reboot bootloader
    6 - Check your current active slot
    fastboot getvar current-slot
    7 - Flash TWRP image into the current inactive slot (we do this just to leave the current active slot with no changes...at least for now)
    If your current active is slot b, then run:
    fastboot --set-active=a
    Or, if your current active is slot a, then run:
    fastboot --set-active=b
    And afterwards, run:
    fastboot flash boot twrp-3.3.1-15-laurel_sprout-mauronofrio.img
    (of course that img file must be on the same path where you have adb and fastboot...)​
    8 - Reboot to TWRP:
    fastboot reboot
    NOTE: Long press Vol+ button before hitting "ENTER" and leave it pressed until you see the Android One logo (just to force boot into recovery)​

    Just a heads up:
    Now we are on TWRP booted on the "previously inactive slot". The "previously active slot" continues unchanged. Nothing "bad" really happened until what we decide to do next. If we want, we can just make a TWRP backup of the current slot and nothing else. Afterwards, we could always reboot to bootloader, change to the "previously active slot" again and boot system. If we do this, we continue without TWRP and root but we would now have a TWRP backup of the system present on the "inactive slot". Anyway let's presume you really want to permanently install TWRP and ROOT your device....so let's continue.

    9 - While on TWRP, install twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip
    Note that, by doing this, TWRP will be permanently installed into both slots. This means that, if someday, you want to revert to stock, you'll need to reflash stock boot.img on, at least, one of your slots.​
    10 - After installing TWRP zip, go to reboot menu, change to the active slot (the one you had on the beginning of these steps) and reboot to TWRP
    11 - After TWRP reboots, install Magisk installer zip
    12 - Finally, reboot to system
    13 - Enjoy

    Thank you @mauronofrio and Jyotiraditya Panda for your work on bringing TWRP to Mi A3 (laurel_sprout).

    I just hope you're able to fix USB OTG and SDCard bugs and, of course, make this TWRP official.

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    #include <std_disclaimer.h>
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you.

    - TWRP boots
    - TWRP seems has problems with external sdcard and otg
    - Magisk Flash works

    Install guide :
    Remember to use the appropriate .img version

    Other Install guide :
    1. Follow this guide to root your device
    2. Flash the TWRP installer like a magisk module
    3. Flashing the TWRP installer you will lose the root, so you will need to flash magisk again from magisk manager before reboot the device or you can reboot the device and flash magisk in twrp

    Before all Disable all magisk modules for boths methods

    - Put rom.zip, twrp installer.zip and magisk.zip on your internal storage;
    - Flash Rom;
    - Flash TWRP Installer;
    - Flash magisk;
    - Reboot.

    If you want you can also update a stock rom from phone settings with local upgrade:
    - Update the Rom WITHOUT REBOOT;
    - Open Magisk Manager;
    - Menu/modules/+ button/select the twrp installer.zip and flash it;
    - Always in Magisk Manager, click on Install/Install/Direct Install;
    - Again in Magisk Manager, click on Install/Install/Inactive Slot;
    - Reboot.

    If you alread have a twrp flashed you can only flash the new installer zip or the new installation method to update your TWRP (remember to flash again magisk or your system will not boot).
    If you have some problems with backup, like 255 error or something similar please check this guide: https://forum.xda-developers.com/oneplus-6/how-to/255-error-twrp-backup-restore-999-t3801632
    For the Bacups use always "system_image" and "vendor_image" instead of "system" and "vendor".

    So i decided to help @Nik001 to make a better TWRP and support this device in the better way, because i'm unable to follow also this device. His TWRP actualy is really stable and soon will be official.

    This is the new thread to follow: https://forum.xda-developers.com/mi-a3/development/recovery-unoffical-twrp-xiaomi-mi-a3-t3987759

    Moderator please close this thread
    I decided to open again this thread and i decided to update the TWRP for android Q compatibility. I update the first post with a guide and a really similar guide can be found at the download link.
