My Experience rooting the T-Mobile Revvl 6 5G



The T-Mobile Revvl 6 5G is a Mediatek MT6833 Dimensity 700-powered smartphone with an Android 12 Operating System. The client’s goal was to root; unlocking the bootloader first and then rooting.

Unlocking the Bootloader

Just to test, I tried unlocking the bootloader using fastboot but none of the commands worked. I had to turn to bootloader unlocking using MTK Client.

Entering BROM Mode

To use MTK Client, you need to get this model into BROM. To force the T-Mobile Revvl 6 5G into BROM mode, you power off, hold the volume decrease button then connect to the PC.

Once the Bootloader is unlocked, your screen will show a warning on every boot;

dm-verity corruption

Your device is corrupt.
It can’t be trusted and may not work properly.
Press power button to continue.
Or device will power off in 5s

dm-verity

This is normal and your device should boot up fine once you press the power button. If you’re stuck in a boot loop then you must have forgotten to wipe user data after unlocking the bootloader so run this command in the MTK client command line:

py -3 mtk e metadata,userdata

Extracting boot image

The plan was to root using magisk manager so the boot.img needed to be extracted from the phone. I chose to extract only the boot.img. The command was:

py -3 mtk r boot_a boot

If you wish to backup other partitions then here’s a list of partitions for this model

T-Mobile Revvl 6 5G partitiions

It is important to note that backing up large partitions using MTK Client can be very slow so a better approach is to use the payload command to disable security and then (with the phone still connected), do a readback using WWR. The payload command is

py -3 mtk payload

Armed with the boot file, I renamed it to boot.img, then the client patched it using the latest version of Magisk Manager (as at this post) and copied it back to the PC.

Rooting the T-Mobile Revvl 6 5G

Rooting models -like this- which have fastbootD is done by flashing the magisk-patched boot in fastbootD instead of fastboot. You need to have set up adb and fastboot already.

To get into fastbootD from ADB, you run the following commands:

adb devices
adb reboot-bootloader
fastboot devices
fastboot reboot fastboot

Wait till the device enters fastbootD. Assuming the magisk-patched boot is named magiskboot.img, your flashing command would look like this:

fastboot flash boot magiskboot.img
fastboot reboot

Check for root in Magisk Manager once the device boots to the home screen.

How to bypass FRP on T-Mobile Revvl 6 5G

If you ever need to bypass Factory Reset Protection (FRP) on this model then you can easily achieve this by wiping the frp partition then rebooting. The command to bypass FRP is:

py -3 mtk e frp

  1. Why does it seem everyone is avoiding porting twrp to this device? I’m beginning to think there is a bottleneck on how much info is given. Wouldn’t make money if all the info was given. Or you guys cannot deal with the security. Either way I sense this phone being neglected on purpose

  2.  Pls … help me with the file of infinix x690b

    sec1
    scp2
    sspm_2
    gz1
    gz2
    lk2
    tee2
    otp
    flashinfo

    The files of My phone’s model isn’t among the ones listed here—–>>>
    https://www.hovatek.com/forum/thread-34324.html

    So I downloaded 2 stock rom zip files of this device from different sources, but it doesn’t contain these files.. and the baseband wasn’t fixed.

    The files were only able to fix the constant nvram wifi notification error. 
    The phone’s build number is X690B-H691DE-Q-GL-220215V356

    I’m hoping that if I can flash the phone with the complete files, (using mtk client) I’ll fix the baseband unknown issues, and then proceed to writing imei. 

    Pls shelp me with the files.. Thank you
