1. [How to update to latest OOS]

I hope you aren't so dumb, but simply "System Settings, Updates, Update, yes yes yes i want to update pleamze cheemz".

Q: Why updating to latest OOS? 
A: crDroid 6.7 is based off Android 10, and the system should start from A10 Vendor image, else it won't boot :)

2. [How to unlock bootloader]

!!! NOTE THAT THIS STEP WILL WIPE EVERY DATA CONTAINED INSIDE YOUR DEVICE. PLEAMZE BACKUP IT CHEEMZ

Assuming you're still on OOS you need to enable developer options (the famouse "spam taps on Build Number inside system informations) then enable "Allow OEM unlock".

After that, from a adb shell, reboot to fastboot and unlock the bootloader with those commands:

- adb reboot fastboot 
- fastboot unlock

After unlocking the bootloader, the system will start again with "Welcome to OOS". Proceed to the next step

3. [TWRP pt. 1]

After downloading the TWRP image, reboot the phone in fastboot mode:

- adb reboot fastboot

Then boot the TWRP image using:

- fastboot boot <RECOVERY.IMG>

(I hope you aren't so dumb to type "<RECOVERY.IMG>" :haha: replace it with the path of the previously downloaded image)

Now that you're in TWRP, go in "Reboot" menu and assure that you're running on active slot "A". If not, select it and repeat step 3.

Then in "Wipe" menu, wipe "System", "Dalvik/ART cache" and "format /data"
After everything is wiped, return to "Reboot" menu and select "B" as active slot. Reboot again in bootloader mode and repeat step #3.

4. [TWRP pt. 2]

After wiping both slots, put in "sdcard":

- crDroid zip
- TWRP installer
- * OpenGapps Installer ZIP
- * Magisk ZIP


Then in order:

1. Flash crDroid ZIP
2. Flash TWRP installer
3. Reboot to recovery mode
4. * Flash OpenGApps

!!! Please note that the 3rd step is required as the active slot will switch from B to A (B->A)

Now repeat again steps 1-4 then boot the system


5. [Magisk]

!!! PLEASE NOTE THAT MAGISK ZIP INSTALLER SHOULD BE FLASHED TWICE (one for A slot, another for B slot)

In order to install Magisk you should have both slots working (one for backup).

To check this you can follow those steps:

1.  Reboot the phone in fastboot mode, then from a shell run "fastboot get_active": 

$ fastboot getvar current-slot
current-slot: a

Reboot in recovery mode, then flash Magisk.zip.
Finally, select slot "B" as booting slot, then reboot to "Recovery"
Reflash Magisk again, and you have a working Magisk on both slots :)

For any trouble don't hesitate to dm me on Telegram: @trmoncode


6. [Troubleshooting]

Q: ctsProfile is false, how to fix it?
A: In order to pass SafetyNet test, you need:

- Magisk
- MagiskHideProps module
- Ozmosys Busybox

Install Magisk as per step 5, then, after booting the system, install the modules.
Then fire up a shell and:

$ su
$ props
$ 1
$ f
$ 20
$ 9

This will set the right fingerprint for the device and will make you pass the SafetyNet :)
