For myself it all worked.

make sure you enable developer options and check "allow oem unlocking" before attempting bootloader unlock.

once bootloader is unlocked TWRP can be loaded.

Root can be achieved using latest magisk, all thanks to [MENTION=4696121]Shug69[/MENTION] for finding this out.

While I found the tablet to be a lot more snappy than the 2GB version, I still went ahead with the run unencrypted script. Feels better to me but I do this with all my devices.

Also someone said there MM tablet was not encrypted to begin with, mine was. Just check under settings/security. If it says "encrypt tablet" then you are not encrypted.
[Thinkpad Tablet General] stapler85:
ok im still new to the tablet so i chcked the settings, have ticked unlock bootloader, security says encrypted so mine is definitely encrypted, however, what do i need to do to disable encryption? i read the first page and im still not certain how to go about doing it, mostly the order of things, and does the unencrypted script work on the 4gb update version?

and if i just want root do i need to do any of the above or simply run magisk?\

EDIT: sorry im confused mainly because the red text in first post saying NOT to do it on the 4gb version so i just need steps on what to do for this updated version i got, i just want root on it ultimately.
[Thinkpad Tablet General] joesnose:
So to root or run unencrypted require TWRP. TWRP requires that you unlock bootloader.

All works on 4gb version. Although if you read the last couple of pages some seem to be finding it a little difficult. Woorked just fine for me. As always FIRST thing you do when you get twrp loaded up is make a backup.....this is a must.
[Thinkpad Tablet General] stapler85:
ok when i booted in fastboot mode, secure boot and lock state is still both shown locked AFTER i have ticked OEM unlock in dev settings, is this correct? and when i try the fastboot oem unlock command and the new command too the command window just hangs on "waiting for device"
[Thinkpad Tablet General] joesnose:
This means your pc is not recognising your tablet. You probably need to update your fastboot drivers.
[Thinkpad Tablet General] stapler85:
i have already installed the fastboot linked in first post, is there a newer one than that? i tested by opening anywhere cmd line for adb and it works, so does it mean its installed properly?

have also tried other commands its talking to it properly, adb devices and adb fastboot reboot etc but as soon as i go fastboot oem unlock or fastboot flashing unlock it hangs on waiting for device and nothing happens on tablet.
[Thinkpad Tablet General] joesnose:
Indeed, I don't think the fastboot linked in the first post​ supports...

fastboot flashing unlock

...which is the command needed.

If you install minimal android ndk should give you up to date drivers.
[Thinkpad Tablet General] stapler85:
sorry im not sure how to install minimal android ndk, google takes me to github which i dont know how to use, ive tried minimal adb dated Jan 2017 and still says waiting for any device ahh this is frustrating
[Thinkpad Tablet General] joesnose:
There is a guide here that might help.

[Thinkpad Tablet General] stapler85:
still trying to load right fastboot drivers from the SDK(not sure how to do it), still showing up as cherry trail tablet with exclamation mark in fastboot mode plugged in. fastboot devices not showing anything up so its definitely something not right

---------- Post added at 01:29 PM ---------- Previous post was at 01:12 PM ----------

fastboot just doesnt respond, i dont understand, i tried reinstall multiple adb and fastboot drivers, how can i uninstall all fastboot drivers and start again
[Thinkpad Tablet General] joesnose:
Have you tried this installer? Or is that the one you were already trying?
[Thinkpad Tablet General] stapler85:
im pretty sure its installed, have updated SDK too, running from Android\platform-tools so this should be latest adb and fastboot?

i just ran fastboot devices from Android\platform-tools freshly downloaded, and it still doesnt respond?!
[Thinkpad Tablet General] joesnose:
I would have thought so. Try going to device manager and uninstalling drivers for cherrytrail, as I remember it needs to say intel. Then reboot and try again. Or try manually install driver and select google one.
[Thinkpad Tablet General] stapler85:
Have uninstalled from device manager while in fadboot mode...replugged in still shows up same as before, tried to reinstall google usb drivers and pointing it manually to driver folder in fastboot mode still doesnt work, what else now :( how should it look in device manager when fastboot responds? Have also tried to point it to lenovo drivers bundled with tablet still no change.
[Thinkpad Tablet General] joesnose:
Pretty sure it should say intel adb device, but I am not at my computer to check! Sorry.
[Thinkpad Tablet General] joesnose:
here's the driver
[Thinkpad Tablet General] stapler85:
its...beautiful....finally!! fastboot responds! and i did fastboot flashing unlock, for anyone else having problems definitely use these drivers.

now to root it, for 4gb version do i still need to flash supersu.zip from first post or only flash magisk.zip?
[Thinkpad Tablet General] joesnose:
FIRST make a full twrp backup before root or anything else.

Just use magisk. As I understand supersu gets it stuck in a bootloop.
[Thinkpad Tablet General] stapler85:
yep backed up everything in TWRP, ticked everything, also backup the new boot after disable encryption, have moved all the backup to my pc just in case the SD card plays up.

rooted with magisk and root works like a charm, for anyone on 4gb wanting to do it i did disable encryption first and then root, i figured it would wipe data so might as well avoid dramas if any.

thanks so much!! happy to help others if they run into similar issues as i spent hrs last night figuring out everything.
[Thinkpad Tablet General] joesnose:
Great stuff.
[Thinkpad Tablet General] rumteldat:
Hey guys, I rooted my tablet a while ago, but now I want to go back to my old install. I backed up everything before I rooted it, but I have no clue how to restore my backup. Can anyone give me a quick guide?
[Thinkpad Tablet General] joesnose:
Hello.

Connect tablet to pc.

open command prompt from the folder where you downloaded twrp. (This can be done by holding shift and right clicking in an empty area of the explorer window)

In the command window....

adb reboot bootloader ( or manually boot to bootloader, with power off hold volume up key and power on)

Once tablet is in bootloader (green android and other infos displayed on screen) in command window enter

fastboot boot twrp.img

Replace twrp.img with the name of twrp on your pc.

Tablet should boot to twrp. Restore backup.
[Thinkpad Tablet General] rumteldat:
I think I've run into a problem. I remembered that I upgraded my PC's OS from win7 to win10, when I try to run the fastboot command it just tells me it's not recognized. I still have the backup but it's on a different drive. Any idea's?
[Thinkpad Tablet General] joesnose:
@ rumteldat You need to install fastboot drivers. Easy installer is linked in first post.
[Thinkpad Tablet General] rumteldat:
Would it be called something like "YOGAC133B4ED"?
[Thinkpad Tablet General] joesnose:
if that's what you get when you...

fastboot devices

that's it.
[Thinkpad Tablet General] rumteldat:
It's telling me permission denied.
[Thinkpad Tablet General] joesnose:
what command?
[Thinkpad Tablet General] rumteldat:
Never-mind I'm an idiot. I figured it out. Thanks for the help.
[Thinkpad Tablet General] stapler85:
now that ive had some time to play and debloated the stock rom, i do agree, while its a fast tablet(antutu scored 89k after debloat) there are small software bugs glitches here and there that only appears when you spent serious time with it, nothing major and not sure its just me killing something in process of debloat but some settings like time and date gets reset when its rebooted, couple of other settings also get reset to default after reboot, not sure its got anything to do with decryption or bootloader unlock either(i know its weird but its only explanation i have)

coming from a samsung note tablet the stock firmware could do some polishing, although i highly doubt chance of any roms given the tablet's history, besides the zenfone 2s, Intel atom SoCs probably have the worst chance of roms, probably worse than Mediateks'
[Thinkpad Tablet General] joesnose:
I agree the chances of a custom rom are nil.

But the resetting clock thing, I don't have this problem. I am rooted, running unencrypted and have only done some minor debloating. And no problems rebooting.
[Thinkpad Tablet General] stapler85:
is there another forum or within XDA section where this tablet is discussed? the lenovo forum itself doesnt offer much in the ways of customizing and tweaking and information seems scattered about on the internet, just want to see if i could contribute in some way to the development
[Thinkpad Tablet General] joesnose:
There is really not much going on for the YTP3. Probably due in the most part to the high price, this limits the user base immediately.

Then there is the incomplete sources published by lenovo.

root on android 6.0.1

to joesnose

Is there an easy way to put a root on Android 6.0.1? Magisk is very buggy and does not correctly mount data.
[Thinkpad Tablet General] joesnose:
what's your issue ?
[Thinkpad Tablet General] stapler85:
ok the first OTA update is out for 4gb in the form of 89mb

however, as tempting as the bug fixes and stability promise, will it break anything such as root encryption etc all the works been done on our tablet?

also you can see the build number went from 013 to 232, thats quite big jump and seems positive.
[Thinkpad Tablet General] vasvas123:
to joesnose

magisk

Not in time mounts the date, as a result, the time zone is lost. Plus a modified boot does not allow to receive ota updates Regards))

By the way on 4pda.ru there are firmware on x90l if this helps someone then welcome)))
[Thinkpad Tablet General] dskmusic:
some news about root of the new 4gb version?
[Thinkpad Tablet General] vasvas123:
Apparently the same Magisk curve is necessary with the removal of encryption from the respected joesnose otherwise it does not work.
[Thinkpad Tablet General] dskmusic:
why lucky patcher not work with this root?
[Thinkpad Tablet General] vasvas123:
Unfortunately I do not use it, but kernel adiutor and root explorer are operable
[Thinkpad Tablet General] joesnose:
I know it is a big ask but can someone with the 4GB wifi version upload their twrp backup somewhere. I was trying some things to fix the root issues and borked my system! And my twrp is failing with a bloody error!!!!
[Thinkpad Tablet General] stapler85:
i think that was what my problem was, the timezone and the time itself keeps resetting after reboot, i had no idea it was related to magisk, even though root works for me.

however i was able to still receive OTA notification(i ofcourse have not install it)
[Thinkpad Tablet General] beaufort8:
I was trying the OTA but not successful.

Unlocked bootloader and msgisk 12.

Do I need to restore bootimage and lock bootloader?
[Thinkpad Tablet General] joesnose:
In fact if someone could just upload the system.ext4.win001 file from their backup it might work. That is what seems corrupted on my backup.

Anyone?
[Thinkpad Tablet General] Shug69:
Edit sorry wrong file - just woke up.. correct file coming soon
[Thinkpad Tablet General] joesnose:
Thanks for that shug69. strangely that is a completely different size from mine, mine is about a gig and a half! Lol.

Any chance you could just upload your whole backup. Sorry to be a pain.
[Thinkpad Tablet General] Shug69:

Here is a full firmware 6 Android any file can be stitched directly to the fastboot with a computer

[Thinkpad Tablet General] joesnose:
Thanks again shug69. don't know what's going on as that one was also a slightly different size but restore finally completed :)

Cheers brother.
[Thinkpad Tablet General] joesnose:
Thanks for the link. Managed with the file shug69 uploaded.
[Thinkpad Tablet General] joesnose:
I personally have no problems with magisk, seems to work well. I have tried to get other root apps working but have been met only by dead ends. Somebody with a small amount of knowledge could probably sort this out quite easily.

Having screwed up my tablet and having to start out at square one I installed the latest update, guessing it's bug fixes as nothing stands out as a new feature. But it still roots and runs unencrypted just fine.

I also ended up with the annoying timezone setting to China upon reboot. Easy fix is to edit build.prop or install build.prop editor from the play store.

Edit the line......

persist.sys.timezone

To reflect your location. If you are in Britain change it to Europe/London as this will give you British Summer time.
[Thinkpad Tablet General] joesnose:
Was just having another think about this as I have ran a live version of androidx86 cm13 on my tablet. There is lots broken at the moment, but is is regularly maintained and is getting better all the time.

At the moment there is no touch, sound, bluetooth, hardware buttons and lastly HWacceleration.

So not really worth running at the moment, but it seems to be getting more and more cherrytrail all the time. A few weeks ago it didn't even boot.

So it might be worth focusing your efforts there.
[Thinkpad Tablet General] stapler85:
wait how were you able to install x86 iso on USB without UEFI on the yoga tab?
[Thinkpad Tablet General] joesnose:
I didn't install it, I just ran a live session from usb.
[Thinkpad Tablet General] mletchworth:
joesnose - props for keeping this thread going for us. Do you have the 4GB version now? Any chance porting that version of MM to the 2GB model?
[Thinkpad Tablet General] joesnose:
I do have the 4gb version now. Not sure that is within my scope but will take a look into it when i can find some time, wheres ionioni when you need him!

Apart from the processor i don't think much has changed hardware wise, it might be that it would just work but i wouldn't recommend biting that bullet.

I cant believe that the 2gb version has not been updated still! This was my first lenovo device and most certainly my last!
[Thinkpad Tablet General] dskmusic:
Root for the new 4gb version, please!!! :)
[Thinkpad Tablet General] joesnose:
Sorry dskmusic, i thought you had managed already. Where have you got too and what level of rooting experience do you have?
[Thinkpad Tablet General] dskmusic:
Well, Im waiting my second tab 3 pro (the first brick in a strange way).

The first tab brick after restore to factory reset. I rooted it with magisk, and works fine (but some app not recognized by root).

Then I install a stock rom via dnx mode to restore it, version 5.0.1., all working fine. Then, I updated via OTA, and after an error during the update the screen go off forever!

Now the tablet power on (vibrate), but the screen is always off :/

I want to root thi second tab, but I'm not sure if I can get all apps that I need working fine with root...

I 'm thinking in flash "SuperSU-v2.76-magisk" before install magisk, but i'm not sure if this will work.. and I dont want brick my tab :)

Some advice?

Thanks and sorry for my english, I'm spanish ;)
[Thinkpad Tablet General] joesnose:
from what i remember that supersu will cause bootloop, not brick can just restore in twrp.

I just flashed magisk in twrp and all seems fine. All apps working for me.

Havnt tried lucky patcher, is that the problematic app?
[Thinkpad Tablet General] dskmusic:
yes, is the app
[Thinkpad Tablet General] stapler85:
the saving grace for me of this tablet is the very decent spec on the 4gb version and the projector, if it wasnt for those i would've jumped on a galaxy tab s2 or s3, unless YT3P gathers a decent community to have software support i cant see myself keeping this tablet very long, just getting root consistently proves to be difficult at this time, and the chance of bricking here and there just adds to the fear of messing with the device more.

on the other topic i wanted to apply the OTA update, without wiping and starting the unlocks from scratch, does the guide on the first page work? with restoring etc
[Thinkpad Tablet General] joesnose:
I tried it once on the 2gb version and never succeeded.
[Thinkpad Tablet General] mletchworth:
Just installed the marshmallow beta on my 2GB. So far no FCs or other issues but I haven't even installed any apps yet.
[Thinkpad Tablet General] joesnose:
? You installed rom.from 4gb version or release.from lenovo?
[Thinkpad Tablet General] mletchworth:
No there's a marshmallow beta for the 2gb version

https://forums.lenovo.com/t5/YT3-X90F-Marshmallow-BETA/gp-p/lt_gp01_en

You have to request access to the beta group

BTW, I was able to fastboot into TWRP just fine but when I installed the superSU 2.46, it stalled at the boot screen. Had to reinstall the beta through stock recovery
[Thinkpad Tablet General] joesnose:
On the 4gb marshmallow you have to use magisk not supersu. And unenvyption script still works.
[Thinkpad Tablet General] mletchworth:
Nice! I was a little scared to try the encryption after the original root method failed, but I'll give it a shot now.

I am using Magisk on my phone now, but it was baked into the ROM. So I'll give it a shot. Will be really nice to restore my apps with TiBU
[Thinkpad Tablet General] joesnose:
Works like supersu just install magisk zip in twrp.

somebody know where to download sotck rom android 6 for 4gb model?

I brick my tab :/ please, if someone have the info share it!

Im ready to flash trough DNX mode

thanks!
[Thinkpad Tablet General] joesnose:
Can you load twrp? And how did you brick?
[Thinkpad Tablet General] dskmusic:
Yes, I can load it.

I really dont understand what happend.. I only start it, aply an ota update, and then make a backup from TWRP. then, android not load :/ I try to restore my copy, but dont work

Do you not have a backup from before you took the update?
[Thinkpad Tablet General] dskmusic:
Yes, but I when restore, the tablet dont load android

Firstboot can take ten mins.
[Thinkpad Tablet General] dskmusic:
dam.. I restore a rom with 5.0.1, and works... but now, I can launch TWRP trough fast boot mode, its says "command not found"..

---------- Post added at 07:51 PM ---------- Previous post was at 07:48 PM ----------

first boot from a TWRP backup can take 10 minutes?
[Thinkpad Tablet General] joesnose:
Command not found is fastboot error on pc. Actually firstboot takes forever from raw dump flash.
[Thinkpad Tablet General] dskmusic:
well, the stock rom I use to unbrick not support fastboot comand "flashing", but I can unlock it with "fastboot oem unlock"

now Im making a backup of this android 5 stock, then I will try to recover again the original android 6 backup I made first.. and wait for 10 minutes.
[Thinkpad Tablet General] joesnose:
Lol. Let me know how you get on.
[Thinkpad Tablet General] dskmusic:
restore complete, now waiting... with the intel logo on the screen
[Thinkpad Tablet General] joesnose:
Restored marshmallow, stuck at intel?
[Thinkpad Tablet General] dskmusic:
Yes, 7 minutes with this in the screen after restore:
[Thinkpad Tablet General] joesnose:
that's a good soft brick right there. Does your backup include boot and bootloader partitons? And any errors during restore?
[Thinkpad Tablet General] dskmusic:
yes, include all partitions (9 in total).

no errors during restore... some idea?

---------- Post added at 08:31 PM ---------- Previous post was at 08:26 PM ----------

I force a reboot (presing power 10 seconds), now stuck with lenovo logo
[Thinkpad Tablet General] joesnose:
maybe use another backup. I could upload one but it is very slow for me, maybe ask [MENTION=4696121]Shug69[/MENTION] as he seems to be able to upload in a flash. Lol

Where did you get the lollipop backup from?
[Thinkpad Tablet General] dskmusic:

[Thinkpad Tablet General] joesnose:
So you have to put them in your twrp backup folder, save the originals somewhere, then try restoring again.
[Thinkpad Tablet General] dskmusic:
Thanks, I will try it! restore all partitions, right?
[Thinkpad Tablet General] joesnose:
Yes
[Thinkpad Tablet General] dskmusic:

Yes, I can enter fastboot mode, and in PC, I have "YOGA6D86C00A fastboot" in devices.

But I cant unlock with none of this:

fastboot flashing unlock

fastboot oem unlock

This is necesary to load twrp
[Thinkpad Tablet General] joesnose:
On page 72 there is a link to marshmallow firmware. It is for the l variant but should probably work on othe devices. Probably flashes from dnx so no need for unlock. Worth a try. Chdck if dnx is working , boot with both volume buttons pressed and issue the fastboot devices command in cmd, if it shows then download that firmware and try it.
[Thinkpad Tablet General] dskmusic:
yes, ita for LTE version.. but I will to try. thanks, I let you know something asap
[Thinkpad Tablet General] joesnose:
Did you get a response from dnx?
