[Android Q&A, Help & Troubleshooting] NyihuiGamer:
Hi guys, this is my first time creating a thread at XDA. So if there's anything wrong please correct me, and I'm not a native english speaker so I'm sorry if my word is confusing 😉.

I'm not responsible for any damage that will happen to your phone. So DO IT WITH YOUR OWN RISK.

UNLOCK BOOTLOADER WILL WIPE YOUR INTERNAL STORAGE, so please backup your data first before continue.

Rooting process WILL VOID YOUR GUARANTEE so keep that in mind.

If your phone is below version 320, please update your system first at least until version 320.

READ CAREFULLY, skip a step and it might brick your phone.

* If you want to use TWRP and do more with it, go to THIS THREAD to flash TWRP and flash magisk file yourself.

THIS IS FOR INFINIX NOTE 7 (X690B) ONLY. If your phone is X690/X690C I'm sorry but I can't help you since I don't have such phone model 🙇‍♂️.

********** PREPARATION **********

Extract the downloaded files in your PC

Open driverInstall.exe and install it.

Open Root folder, copy all the data to ADB_Fastboot folder.

Put Magisk APK to ADB_Fastboot folder and rename it to "magisk.apk".

In your phone, enable Developer Options.

At Developer Options, enable OEM Unlocking, enable USB Debugging, and set Default USB Configuration to File Transfer.

Plug your phone to your PC and run "cmd-here.exe" on your PC.

********** UNLOCK BOOTLOADER **********

If you already unlocked your bootloader, please skip this step.

In this step, your internal storage will be WIPED.

Type adb devices, there will be a popup confirmation, tap Allow.

Type adb reboot-bootloader. Wait until there's USB logo with Fastboot text on your phone.

Type fastboot flashing unlock. Press Volume UP on your phone to confirm.

If it's done, type fastboot reboot.

Your phone is wiped so set it all up again and do number 5 at Preparation step again.

********** ROOT/FLASH VIA FASTBOOT **********

Type adb devices, there will be popup confirmation, tap Allow.

Type adb reboot-bootloader. Wait until there's USB logo with Fastboot text on your phone.

Type fastboot flash boot boot_magisk.img.

Type fastboot --disable-verity --disable-verification flash vbmeta vbmeta_empty.img.

Type fastboot reboot.

Your phone will reboot. After it goes to homescreen, type adb install magisk.apk.

Plug out your phone, connect to the internet, and open Magisk.

It'll shows a popup "Requires Additional Setup", tap OK.

Your phone will reboot itself and it's finally rooted. 👏👏👏

* If you can't flash boot and vbmeta via fastboot, possibly because you're not installing the driver correctly or you haven't unlock your bootloader yet. So please do that step first.

********** UNROOT/FLASH VIA FASTBOOT **********

Type adb devices, there will be popup confirmation, tap Allow.

Type adb reboot-bootloader. Wait until there's USB logo with Fastboot text on your phone.

Type fastboot flash boot boot_ori.img.

Type fastboot flash vbmeta vbmeta_ori.img.

Type fastboot reboot.

********** RELOCK BOOTLOADER **********

FLASH YOUR PHONE TO STOCK ROM FIRST or else YOU WILL BRICK YOUR PHONE.

Type adb devices, there will be popup confirmation, tap Allow.

Type adb reboot-bootloader. Wait until there's USB logo with Fastboot text on your phone.

Type fastboot flashing lock. Press Volume UP on your phone to confirm.

If it's done, type fastboot reboot.

********** SYSTEM UPDATE **********

You need to flash your phone with clean stock ROM and SPFT. This is optional since almost previous system update is just about security and minor improvement. Use MTK Bypass Tool to flash it without DA file.

If you want to uninstall system apps, I suggest to do it via ADB since uninstalling via root app is modifying your system, dangerous and might brick your phone. IDK if you can do it either. Tutorial is on youtube, just search it yourself.
