You can do it, but keep in mind that could be something not ready yet. It is usually safe for everyday usage.
For example, some time ago I installed a not approved firmware and playstore was not certified, until I installed the verified version.

If so, can I install an older verified version ? after this..

This update fixes an issue where a Wi-Fi scanning prompt repeatedly popped up in certain scenarios.

Ugh .116 was approved for me and waiting to show but I have a feeling because of the .114 patch I'll be waiting until October. Now .116 isn't shown as approved.

    If you have unlocked bootloader and TWRP, you can flash a newer firmware using HuRUpdater

    This steps can be risky for your device if you don't know what you are doing, so try to read some guide about flashing first
    before attempt these operations if you are a new to these things.
    I don't take any responsability of catastrophic failures and loss of data.

    -- I did a titanium backup before the upgrade, but in my case no restore was needed as all data were retained.
    In this simple update no factory reset was triggered.
    Please read the HUrupdater thread also for more informations.


    - Install Unofficial TWRP by Pretoriano80
    - Download HuRUpdater 0.3 and put it in a folder in your sdcard

    -Search the firmware for your device with Firmware Finder

    Make sure you download the correct firmware version for your device (type, region code)
    wrong firmware can brick your device

    I used updated firmware files APPROVED for my device checked with firmware finder app.
    I don't know if flashing NOT APPROVED files will harm your device. You have been warned.

    I successfully updated my device from CLT-L29C636B130 to CLT-L29C636B131
    ***Don't try to rebrand your phone with this method***

    - Use FullOTA-MF images of the firmware and download the 3 files needed
    in my case:

    update.zip
    update_data_full_public.zip
    update_full_CLT-L29_hw_spcseas.zip

    - rename the 3 files to:

    update.zip
    update_data_public.zip
    update_all_hw.zip

    and put the files in the same folder with HuRUpdater 0.3

    (optional)
    - The Update will overwrite your TWRP custom recovery so to retain it automatically rename the TWRP IMAGE
    twrp_clt_0.1.img to recovery.img and put in the same folder with others files.

    - Remove all security locks from your phone before rebooting to TWRP.
    Go to System- Developer Options
    Disable Screen lock (third row)
    this will suffice to remove the security locks of the phone (sequences, pin,fingerprints)

    -Reboot to TWRP
    If you are rooted, remove Magisk first with its uninstaller. I don't know if it's needed but better don't have things like that
    messing around during the update. You can reroot later anyway.

    -Go to the folder with the files and flash the system using the HuRUpdater_0.3.zip ONLY
    That great tool will do all the job needed. After system, it will reflash the TWRP recovery IMG you previoulsly renamed
    overwriting again the stock ramdisk_recovery that comes with the firmware.

    It will take some minutes, don't panic and let the process end.
    You will see some red errors but don't worry,it's fine

    - Reboot in your TWRP to check (from inside TWRP , reboot - recovery, be sure not to have a usb cable plugged or it will trigger stock EMUI e-recovery)

    - Wipe dalvik and cache

    - Reroot new system with Magisk

    -Reboot to system and restore the security lock in developer options

    - Restore your fingerprints and pins

    - Enjoy the update. :D

    Thanks to @zxz0O0 for this great Tool, works good on P20 pro too.
    And obviously @Pretoriano80 for his recovery.

    If I reinstall twrp by renaming it as recovery.img, will HuRUupdater install the twrp in recovery_ramdisk, or will it replace eRecovery instead?

    If twrp doesn't replace eRecovery, how do I get to eRecovery? As of now, whenever I want to enter recovery, it will get to twrp.

    eRecovery is not replaced.
    To enter there try other volume button or with a cable plugged

    Working adb sideload?
    I have not tried that, it depends on the TWRP recovery, let us know if you try

    when booting there is a screen prompting to whether you want to go to eRecovery by pressing up or just boot into system and something ike that
