    This method is tested by me and it works perfectly for any rooted stock 4.5.x devices, without losing any data.

    You will need the following:
    1. Take a.full backup of all necessary files, just in case.
    2. Download 5.0 Rom from here: https://drive.google.com/file/d/1AfnQPT3-zGj85fVDH3Go3q5Ph9PzfDD4/view

    Download 5.0.1 Rom from here:

    3. Download the new recovery twrp-3.1.1-x_blu_spark_v8.54-op3_op3t compatible with OREO:
    https://drive.google.com/file/d/1CishERJ9wZ7Kv2SfK4ZPS6_xE9Yi7Bl1/view?usp=sharing

    Latest twrp-3.2.1-x_blu_spark_v8.61-op3_op3t
    twrp-3.2.1-x_blu_spark_v8.61-op3_op3t.img
    4. Download this 14.6 magisk file for root: https://drive.google.com/file/d/1ERm82SQH770nm2QPg2-jNviINwO5fD7I/view?usp=drivesdk

    Magisk 15.2 from here:
    https://drive.google.com/file/d/1MdrbqbjJZdvZgN4ci1OIAB5dtKPSYQ27/view?usp=drivesdk

    Magisk 16.0 here:
    https://drive.google.com/file/d/1mVsSyG-px8iwKH5fumdlfKl1bVXmigqc/view?usp=drivesdk

    Now all you need to do is:
    Flash the new TWRP of step 3.
    The reboot into new recovery and flash the Rom of step 2.
    Then without rebooting, flash also the root file from step 4.

    Now reboot and be patient as this going to take some time for everything to settle.
    Now enjoy your Oreo device!!

    P.S. CREDITS to the XDA guys for their amazing work.
    A clean install is recommended for Oreo, in order to avoid any conflicts or bugs from previous apps.

    Buddy I am explaining everything at the first post regarding the flashing of TWRP.

    If you don't flash the magisk file, then your phone will lose the TWRP recovery and it will have the stock one.

    Rooted and with Oreo installed!!
