YT-X705F - Rooting Guide (Android 10.0) - Android Q&A, Help & Troubleshooting

Solution below.

---

For those with the same device, I was able to successfully root + pass safetynet, without TWRP or custom recovery. Since this device isn't yet on the forums I thought I should share my findings.
At the time of rooting, I was currently updated to the newest version available (10) and did this through the regular OTA updates.
Preparations
1. Download Magisk Manager Beta from https://magiskmanager.com/magisk-beta/
2. Download the stock firmware for your tablet from https://mirrors.lolinet.com/firmware/lenovo/Yoga_Smart_Tab/YT-X705F/
3. Download kdrag0n's SafetyNet Fix from: https://github.com/kdrag0n/safetynet-fix/releases
Edit: looks like I missed a step, thanks for the feedback! Point 4 has been corrected to include instructions on how to unlock the bootloader specifically.
4. Unlock your bootloader, instructions on how to enable USB debugging which is needed, can be found here: https://www.shizhub.com/2018/12/how-to-enable-disable-usb-debugging.html, from there you can open your command prompt, navigate to the directory where you have your fastboot and ADB stored, and type "adb devices" to confirm your device is found (a serial number will display on success) - next type "adb reboot bootloader" to force your tablet to restart into it, finally type "fastboot oem unlock-go" to unlock the bootloader. This voids your warranty.
-- end of edit.
5. Enable USB debugging through developer options (go to settings->about->find build # and tap a handful of times until it says you are a developer.
6. Plug the tablet into your PC, and set the default option to Charge only, or go to file transfer mode and enable USB debugging over file transfer.
Steps
1. Unzip the firmware, there should be a folder called Maincode, in it contains "boot.img" as well as adb/fastboot.
2. Copy the boot.img and Magisk apk to the tablet.
3. Install Magisk
4. Tap on "Install" or "Update" beside Magisk in the app and follow the prompts.
5. You will be asked to select a file, select the boot.img you copied earlier.
6. This will generate a file (it will tell you the path) of a patched boot image.
7. Reboot, and copy the patched boot image to the "Maincode" folder from the tablet.
8. In command prompt, type adb devices and make sure your serial number is shown. If not, review the preparations.
9. Type adb reboot bootloader and you'll see a cute little Tux (penguin)
10. Type fastboot devices and ensure your device is shown, if not then it could be bad drivers on your PC or a crappy USB cable. Check device manager on your computer and make sure you see Lenovo ADB. You may have to force it to install it, or you may see a yellow exclaimation mark - right click on the device and force it to install the Lenovo Bootloader option.
11. Next, in the "Maincode" folder where you put the patched image, rename the old "boot.img" to "stock_boot.img" and the patched version to "boot.img"
12. Back in the command prompt, type fastboot flash boot boot.img
13. Reboot by typing fastboot reboot.
Magisk should now be installed, and your tablet should be rooted. Next, you'll want to go into Magisk and do the following:
Steps:
1. Click on the modules button (bottom of the screen, far right option) and at the top you're given an option to install from storage.
2. Navigate to the SafetyNet Fix zip file and select it, then proceed.
3. You will be given the option to reboot - do this. The first time it may go into recovery, but rebooting brings you back to the home screen.
4. Go back to Magisk, click on the gear at the top right - there is an option to hide Magisk from the system, do this and name it whatever you'd like (just not Magisk) - wait a moment, as the app will restart after it installs.
You can check to make sure you pass SafetyNet in the Magisk (now renamed) app, and root status by downloading one of the countless root checking apps on Google Play Store.

Could you let me know a clear way to unlock the bootloader on the Yoga Tab YT-X705F? The instructions you've provided don't point to anything helpful beyond activating USB Debugging.
"4. Unlock your bootloader, instructions: https://www.shizhub.com/2018/12/how-to-enable-disable-usb-debugging.html - do not proceed beyond where it starts talking about TWRP."
I'm looking to root my tablet but cannot as trying to find info on unlocking the bootloader is proving difficult.
Thanks in advance

Thanks for pointing that out! - I've updated my notes above, but if your familiar with fastboot the command is simply "fastboot oem unlock-go", no unlock code needed for these guys. It will wipe your device and void your warranty though, in case you're not already aware.
Cheers!

Thanks for this rooting guide! I was able to root my YT-X705F
Here some comments/hints:
- At first make sure your downloading the right stock firmware. I've tried a different one which results into a boot loop. One way to find out the right version is to start into the recovery mode. In the header you will find the right version. In my case it was YT-X705F_S001130_210508_ROW
- Make sure you have actually unlocked the boot loader. "fastboot flash x y.img" worked, so I didn't recognized that the boot loader was not unlocked. This was reason for "fastboot boot y.img" shows errors "FAILED (status read failed (Too many links))".
- The extracted stock firmware have no "Mainfolder". All files, including boot.img and recovery.img, contained in the root directory of the ZIP file.
- After installing Magisk app (v23.0) it shows me: Installed: N/A, Ramdisk: No, A/B: No, SAR: Yes. According to this Magisk installation guide you have to patch the recovery image instead of the boot.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
- Patching the recovery image was fine with Magisk. No errors was shown. Please note I used the recovery.img
After this I was able to boot the patched image without flashing it:
After "fastboot boot patched_recovery.img" nothing happens. The tablet keeps showing me the Linux Tux image. I have to disconnect the USB cable and then I booted into system.

*Upd. never mind, I download the official rom file from lenovo\
Crap. I patched the boot image with Magisk, and by the time I flashed it - the system got updated from S001133 to S001135, and I'm getting a bootloop. Can someone maybe upload original boot img from S001135?
Or what else can I do? the update isn't on the mirror server yet https://mirrors.lolinet.com/firmware/lenovo/Yoga_Smart_Tab/YT-X705F/

Rooting was successful! Thanks for the guide. Since I cannot find any section in the forum for the YT-x705 tablet, I thought I can have a follow up question in here. The reason I rooted was because alexa app keeps getting removed after each reboot. I rooted as I wanted to convert it into a system app.
So far, I've been unsuccessful . I have tried with the systemizer module and titanium backup. Anyone have any idea how we can retain alexa app after a reboot? Interestingly enough, titanium backup shows alexa as frozen after I install alexa from playstore, despite it appearing in my app launcher. I am unable to unfreeze it. Alexa is then removed after I reboot.

Quick question: What do i do if i don't have a "MainCode" folder, on the tablet or in the extracted folder.
or is that just the folder with the maincode, in it?
Thanks, looks like a good guide!

you're just going into the zip file from step 2 where the boot.img file is. I just followed all these instructions and got my yoga rooted.

ugh...I don't have a device that I can root for a couple of years... and it feels like I'm a complete noob, now!
when i try to flash the boot image I'm getting: FAILED (remote: Partition flashing is not allowed)
When i run fastboot oem device-info i get this:
PS C:\Users\Jim\Downloads\YT-X705F_S001135_210909_ROW (1)> ./fastboot oem device-info
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
(bootloader) Display panel:
OKAY [ 0.007s]
Finished. Total time: 0.010s
So i don't think i am unlocked. even after following the steps. I've got Developer options, Debugging is obviously working, OEM Unlocking is toggled on.
I feel like on my phones we had to run an adb or fastboot command, and then the device would reboot and reset it and it would then be unlocked.
Am i missing something?
Thanks again!!
Jim
p.s. and once i get it working, what roms can i flash? any of the "yoga" roms? or do i need to look at something specific like the 3 or 4?

---

answered my own question!
i had to run: fastboot oem unlock-go
the device rebooted and reset
now i get this:
PS C:\Users\Jim\Downloads\YT-X705F_S001135_210909_ROW (1)> ./fastboot oem device-info
(bootloader) Device tampered: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
(bootloader) Display panel:
OKAY [ 0.007s]
Now on to the next step!
