There is an update from axioo for this device with 64bit OS architecture this new year. This is custom recoveries for Axioo Venge X arm64. Before you can use this custom recoveries, make sure you already use 64bit version OS from Axioo stock rom. Do not use this custom recovery on 32bit OS because it will never work. For 32bit version, you must use this release : custom recovery for axioo Venge X

On previous 32bit release, all of my custom recovery cannot read /data partition due to partition encryption and it’s locked on the bootloader and kernel. This 64bit version doesn’t suffer that issue again, now you can use Backup / Restore feature on any recovery just like it should be. As always, I build 4 flavors of them CMR, TWRP, carliv and PhilZ, you may use whichever you like.

HOW TO INSTALL :

I repeat, before flashing this 64bit custom recovery, you have to make sure you already use 64bit stockrom from axioo, otherwise it will not work !
The partition layout scheme is different between 32bit and 64bit os version, this custom recovery release is using partition scheme layout from 64bit os version. I don’t have any stock rom from axioo, so you have to ask itclinic for that and flash it before using this custom recovery.

Now, let’s continue, To install this custom recovery, you need SPFlashTool program which only available on winblows os platform so … really sorry, I cannot support it because I never use and don’t have winblows. You may refer to this tutorial : MT65xx Flashing Tutorial it is very well explained by Bruno Martin.
Please be really careful using SPFlashTool, especially when flashing ROM not for your device, since it may bricked your device forever.

Scatter file you might need : MT6753_Venge_X_arm64_Android_scatter_emmc

Of course you also can flash this custom recovery using linux or specific apk such as mobileuncle tool or recovery tool, but that’s another story.

HOW TO REBOOT INTO CUSTOM RECOVERY :

To enter the custom recovery mode is pretty easy on this model, just completely power off the device until you feel the device vibrate, indicating it was totally shutdown. Then, hold down Volume Up button then press Power button, hold them both until you see 3 menu list appear, Recovery, Fastboot and Normal.
Scroll or choose between item using Vol up button and select them using Vol down button. On this case, choose Recovery and press Vol down button, wait a sec or two …  then you’ll be entering recovery mode. There are also many apk on playstore such as Quickboot, RecoveryTool, … etc, that can do reboot into recovery directly from alive system, use any one you like.

HOW TO ROOT :

After installing this custom recovery, you can install root and Superuser as usual, I recommend to use latest chainfire SuperSU
