Unlocking Bootloader/ Magisk Attempt

[Perseu5]

Just updated it for you guys. I have a link to the boot image. Make sure you are unlock_critical for the bootloader. This is "tethered" meaning after reboot you have to boot the image again. Working on a permanent solution currently!

Good stuff, OP! Thanks for your continued efforts!

I am excited to see progress. There must be a way to repack the factory image with the modified boot.img. I have been researching this and found a windows app that would do this but fails. It is called SUR 2.0.

Was thinking we could dirty flash the zip with adb sideload.

I will keep researching this on my end and update if I find something.

Alright you wonderful people, I now have a permanent root method for our beloved Surface Duo's! Updating here soon after some testing!

Woohoo!!!!! Hoping no reset required

 

[Perseu5]

No reset required at all. The only time theres a reset is if you have to unlock the bootloader.

Great news would you mind updating the boot.img too? I tried and after booting the patched one it boots back to the bootloader. I tried patching the file from magisk manager with and without the recovery option checked.

Thanks

JUST UPDATED! I will have an app streamlining the process for you all by the end of the week.
Also, make sure youre unlock_critical and you may have to run "fastboot boot magisk_patched.img" a second time if it fails the first time. Flashing the boot works perfectly fine so far.

MAGISK FULL GUIDE (APK for install and other mods coming soon!)

The bootloader unlock is pretty similar to any other phone.
Go to settings>about> click on build number until developer options are enabled. Go back and select system>Developer Options. Make sure to enable OEM unlocking.
(On PC) "adb reboot bootloader", "fastboot flashing unlock_critical", use volume to select unlock. THIS WILL ERASE ALL CONTENT ON YOUR DEVICE.

IF YOU DONT WANT TO DO THIS FROM SCRATCH, SKIP TO PART 2
Go to https://support.microsoft.com/en-us/surfacerecoveryimage
Select Surface Duo from the drop down
Enter your serial number and download the file
Extract the firmware .zip
Extract the Payload file
Moved bootloader to root
Installed Magisk Manager apk and patched bootloader image
Attempted to flash which resulted in "cannot write to partition_b"

PART 2:
download the patched magisk_boot.img from here https://drive.google.com/file/d/1-7NWj8_jFH8AtpTTpXITOv1eh-wo7xlz/view?usp=sharing
adb reboot bootloader
fastboot boot magisk_patched.img

PART 3 - All right, lets make it permanent!
Place magisk_patched.img on your sd root

adb shell
su
cd /dev/platform/soc/*/by-name/
chmod 777 boot_a
chmod 777 boot_b

DEV=$(ls /dev/block/platform/soc/*/by-name/boot_b); echo $DEV
dd of=$DEV if=/sdcard/magisk_patched.img
DEV=$(ls /dev/block/platform/soc/*/by-name/boot_a); echo $DEV
dd of=$DEV if=/sdcard/magisk_patched.img

Reboot and we are good!
I am working on an app to streamline the process as well as provide additional mods and addons to the device. I hope to have something for you guys by the end of the week.
I do plan on streaming some of this stuff (twitch.tv/goingh0st), and am working on a section of my discord for the same thing (World of Gh0st)
Thank you for your support and I cant wait to get more stuff to you guys!

I am trying this out and whenever I get to this step (cd /dev/platform/soc/*/by-name/) I get : No such file or directory from ADB.

Do I need to replace the * with something and if so how/what? Thank you.

Sorry! Do cd dev/block/by-name/ instead

Just updated the tutorial again to reflect this.

This works perfectly, thank you for permanent magisk. The 1st post was also changed to show something similar to this, but it still has the * and didn't work.

Happy to help! I love doing this kind of stuff.
Sorry, updated again lol. I was at work when I made the first edit lol.

Just wanted to thank you and let you know works like a chance on the first try. Can I ask how you patched the boot.img. when I have tried it just boots back to the bootloader. I am using your patched file currently and wanted to update to the latest canary.

Thanks for the great work.

I wish I could say it went smoothly for me. Any suggestions where I went wrong. I should technically be unlocked, but its saying this command is not available in a locked device.

You must have only done unlock critical.

Try this
C:\ADB Tools\ADB Tools>fastboot flashing unlock

That worked. Thanks,

D:\ADB Tools\ADB Tools>adb shell
duo:/ $ su
Permission denied
13|duo:/ $

Tried as administrator as well. Normally no su = no root.

Do I need to install superuser first? or Magisk App?
