Hi, sorry for delay. I don't understand why I need to unlock the bootloader. When booting, the tablet says that the bootloader is unlocked. Are you sure I need to unlock it again ?
Because you need to CHECK THE BOX "DISABLE FBLOCK" which is default unchecked when you unlock the bootloader. With it locked you can't fastboot flash some or all of the files.

When you unlocked it did you CHECK THE BOX "DISABLE FBLOCK"? I think that is the error you get if you don't check that box.

I had that issue also. I needed to disconnect the battery and boot with the test point and use potato to unlock. Then I could flash back to stock manually.

    Hello to everyone!

    Following this guide, you'll be able to rebrand your T5 to Chinese version (W09-C00 or AL00-C00), so you can upgrade to EMUI 9.1/HARMONY 2.0
    (IF YOU HAVE THE HONOR PAD 5 AND YOU WANT TO UPDATE, TALK ME)

    I have a T5, W19 / 3gb ram / 32 internal.
    It worked for me, should work for you too, but I'm not responsible if something goes wrong (well...maybe a little).

    PROCESS:

    1- You need to UNLOCK the BOOTLOADER with POTATONV and you MUST CHECK "Disable FBLOCK" or you'll have problems flashing the IMGs.
    (
    fastboot oem lock-state info - to check if FBLOCK is unlocked)
    Unlock Code Mediapad T5 (2).jpg

    1.1- Check that FRP is UNLOCKED
    1.2- CHECK that HISUITE is installed (for drivers) >>> CLICK HERE TO DOWNLOAD
    1.3- BACKUP YOUR OEMINFO USING TWRP, IF SOMETHING GOES WRONG, YOU'LL NEED IT.

    Follow this amazing guides to UNLOCK your BOOTLOADER:
    SOFTWARE >>> CLICK HERE TO DOWNLOAD
    UNLOCK BOOTLOADER T5 process
    >>> CLICK HERE FOR THE GUIDE
    SAVE YOUR BOOTLOADER CODE, YOU'LL NEED IT.

    2- Download fastboot and oeminfo, extract it and flash it:

    FASTBOOT FILES (USE IT):
    WINDOWS: CLICK HERE TO DOWNLOAD
    LINUX: CLICK HERE TO DOWNLOAD
    MAC: CLICK HERE TO DOWNLOAD

    OEMINFO AGS2 / C00:
    W09 - W19 WIFI ONLY:
    fastboot flash oeminfo oeminfoW09C00.img
    https://www.androidfilehost.com/?fid=14655340768118449368

    L09 LTE (don't know if it will work on L03):
    fastboot flash oeminfo oeminfoags2al00c00.img
    https://androidfilehost.com/?fid=14655340768118450716

    YOU CAN ALSO USE TWRP TO FLASH OEMINFO, IF YOU DO THAT, FLASH IT AND REBOOT INTO BOOTLOADER TO CONTINUE THE PROCESS

    3- Now, download and extract the zip, flash the IMGs inside and wait for the best:

    FILES FOR AGS2-W09 & W19
    https://www.androidfilehost.com/?fid=14655340768118449355

    FILES FOR AGS2-L09
    https://www.androidfilehost.com/?fid=14655340768118459545

    Flash this files in FASTBOOT
    fastboot flash system system.img
    fastboot flash vendor vendor.img
    fastboot flash fastboot fastboot.img
    fastboot flash kernel kernel.img
    fastboot flash ramdisk ramdisk.img
    fastboot flash recovery_ramdisk recovery_ramdisk.img
    fastboot flash cust cust.img
    fastboot flash version version.img

    ***Reboot into STOCK recovery and format data***

    *If the above files doesn't work, try flashing the firmware with DLOAD method.
    Download the zip and extract the DLOAD folder into the root of your SDCARD, reboot the tablet pressing VOL + and VOL - and wait...
    *


    DOWNLOAD DLOAD W09-C00

    DOWNLOAD DLOAD AL00-C00

    4- Now, the phone should boot normally, rebranded and with the chinese firmware.
    Now, go to settings and check for update, you'll see an update to PIE available.

    You'll need to install all the PIE updates before the server sends Harmony, or... you can send the Harmony update directly with this:
    https://professorjtj.github.io/ (AGS2-W09 - C00) (AGS2-AL00 - C00)
    https://github.com/ProfessorJTJ/HISuite-Proxy/wiki/Complete-Guide (follow instructions, very easy to use)

    Upgrading to Pie/Harmony locked my bootloader, but if you saved your code, write it again and unlock it again ^.^

    Thanks to @Fosanz for its help.

    Thanks to @iceows for the script and steps to edit the oeminfo: Go to the link
