hello this is only my second walkthrough so bear with me. you cannot TWRP this phone i tried everything. you can only root it with Magisk. im going to supply the files needed but you are going to need to follow the walkthrough instructions for mtkclient to backup your phone and root it.

1> here is a link to setup mtkclient: https://xdaforums.com/t/guide-mtk-how-to-use-mtkclient-and-set-it-up.4509245/#post-87941231

2> open the mtkclient main folder and create a folder named Vortex HD55

3> turn on developer options on your phone, to do that tap build version or build number or whatever 7 times, then go back into the system setting and tap on developer options then turn on stay awake and turn on OEM unlocking and turn on USB debugging, then scroll down and click Default USB configuration and select File Transfer then exit out of that stuff.

4> unzip the latest platform tools, then in windows go to Edit the System Environment Variables settings and click on Environment Variables button. at the bottom of the menu it has a button called New, click on the New button and in the Variable Name box type in ADB_HOME, and in the Variable Value box navigate to platform tools and add the folder that has adb.exe in it. then highlight Path in System Variables and then click the Edit button at the bottom. when the next window opens click New and put the same path to where adb.exe is in there. then click ok and your done with that part.

5> install device drivers then plug in your phone for a while and check optional updates in windows update for the Mediatek and the LeMobile drivers and download and install them. after they are installed plug in your phone to the computer and open a Command Prompt and type the command without quotes "adb devices" and it should show List of attached devices and your phone if its plugged in. if all that goes well and its detecting your plugged in phone you can continue to the next steps. if its not detecting it make sure your drivers are installed correctly somewhere else on the internet and also look up on the internet setting environment variables for adb.

6> open a command prompt and type in "adb devices" after it detects your phone type in "adb reboot bootloader". after its in the bootloader type in "fastboot devices". if its reading your device everything is correct so far. next type in "fastboot flashing unlock --disable-verity --disable-verification" then hit the volume up button on your phone. now your bootloader should be unlocked. doing this factory resets your phone, boot up your phone and do all the same stuff for developer options. and set up your phone fully.

7> then navigate to the mtkclient main folder and click on the mtk gui icon and follow its instructions to connect your phone, sometimes there are errors connecting it so keep trying until you get it.

8> once connected options will show up, select the read partitions tab and check the select all partitions box then hit the read patitions button, its going to take about an 45 minutes or less to do but its a full backup of your phone.

9> after its done hit the write partitions tab and scroll down to boot_a. hit the Set button and navigate to where you have magisk.bin saved and select that. then hit the Write partition button. it will be done in less than 40 seconds. then unplug your phone and boot it up, i have a magisk apk attached to this walkthrough you can use if its not already installed.

10> also instead of using my magisk.bin you can make your own with magisk and use that, you need to get the boot_a.bin and put it on your phone in the download folder or something then use magisk and select install then select patch a file then select the boot_a.bin file you put on there and then write that file to your boot_a partition with mtkclient. might be better to use your own jsut because this one is frrom my phone but i dont mind its just a spare phone i have.

and viola your phone is rooted. if you figure something out with TWRP or a custom recovery let us know! im also attaching a Command.CMD file its my custom command prompt, its only 1kb so you can copy and paste it to any file you want to use it in. or not its up to you. if i left something out let me know...sign up for xda to write a reply if you brick your phone i can probably help you fix it. i will be checking this thread often.
