Almost certainly a driver issue .

Some suggestions, try another USB port on PC, try using another PC or load live Linux session on yours.
[Thinkpad Tablet General] corti96d:
I have a big problem now. I tried with Linux... and it worked. I saw my device typing "fastboot devices", so I wrote "fastboot oem unlock". Everything worked fine, so i tried to rewrite "fastboot devices" to see if something was changed and now i have "no permission fastboot" while before the oem unlock i had a serial number or something similar. I tried to boot the twrp but now it says me "< waiting for device >" again.

I can't use my tablet, when I start it, it shows me "Bootloader error code 03 - START Press Volume UP key - FASTBOOT Press Volume DOWN Key". If I press volume UP, it reboots in the same Error code, if i press volume DOWN it goes in FASTBOOT, but I don't know what to do. Is it bricked? Why?
[Thinkpad Tablet General] joesnose:
What is the model number of your tablet?
[Thinkpad Tablet General] corti96d:
X90F
[Thinkpad Tablet General] joesnose:
Still not showing in fast boot?
[Thinkpad Tablet General] corti96d:
No.. in windows the "fastboot devices" command returns 0 lines... and I think it's a driver issue, it will never work on windows.

On Linux the "fastboot devices" command returns "no permission fastboot"... so it sees my device but it doesn't have permission to boot the twrp.

I retried to do the oem unlock and now it worked all. Just flashed the TWRP, i'm going to do the other things... I hope to have no problems now. Thank you ;)
[Thinkpad Tablet General] joesnose:
Good work and good luck. Make a backup before any flashing!!!! Lol
[Thinkpad Tablet General] corti96d:
I don't know how to start my tablet! It's blocked in BOOTLOADER ERROR CODE 03! I can only access to fastboot mode... if I try to START, it reboots in the error page.....
[Thinkpad Tablet General] corti96d:
All OK. I had to relock the bootloader in order to start the tablet. After that i wanted to modify the encryption data, so I reunlocked the bootloader, flashed the zip and after that the device rebooted normally. So strage that the same tablet with the same procedure, worked in 2 different ways...

There's been a few of these recently! Glad it's all sorted. Enjoy.

4go RAM and 64go ROM version (android 6.0)

Hi all !

Thanks for this very useful thread !

I bought a X90F version (2go RAM and 32go ROM, android 5.1) 3 months ago and followed this tutorial to root it and un-encrypt it, and it worked very well.

But when I saw the "new" X90F version (4go RAM and 64go ROM, android 6.0) on Lenevo website, I could not resist to aditional RAM and I bought it.

So here is my question : is this tutorial working on the new version, even if it is android 6.0 and not 5.1 ?

And if yes, will I still have android 6.0 at the end ?

If not, do you think it would be easy to adapt it to the new version ?

Sorry if this question seems stupid to you, I am not very good in rooting theory.

Thanks in advance for your help ! :)
[Thinkpad Tablet General] joesnose:
In theory it should just work.

If bootloader can be unlocked.

And does it actually have marshmallow on it?
[Thinkpad Tablet General] Masterofmichou:
I don't know yet, it should arrive tomorrow :)

Ok thanks ! Why in theory ? Nobody tried it before ? The android version does not impact on the root method ?

So do I have to follow exactly the same tutorial ?
[Thinkpad Tablet General] joesnose:
Well if you can unlock the bootloader and load twrp you should be good to go.

If you get that far make sure you MAKE a BACKUP. Can't stress that enough.

Instructions should be the same, though I don't know if the OEM unlock will be there IF it is indeed marshmallow.
[Thinkpad Tablet General] Masterofmichou:
Ok thanks a lot for the advices and the quick answer !

I'll try it tomorrow and may ask you some questions if I am in trouble ;)
[Thinkpad Tablet General] Alan-B:
Hi,

I also bought three months ago the LTE version 2Giga of ram and 32 Giga of memory! And here is that a version 4G of ram and 64G of memory at the same price goes out!!

The root worked well on the 2G, me wait to see if it is OK also on the 4G?

For Masterofmichou: the 4Giga in the good the projector?

Désolé pour mon Anglais !
[Thinkpad Tablet General] mletchworth:
Are you sure about that? I'm not seeing a new Yoga Tab 3 Pro on their website. There's a Yoga Book with 4gb RAM, 64gb storage and Android 6.0 but the hardware looks completely different than the Tab3Pro (X90F).

Hi,

to this adresse . . .

https://www.amazon.de/Lenovo-Convertible-Tablet-Quad-Core-Kamera/dp/B01LY6SK41
[Thinkpad Tablet General] joesnose:
If you read the description it says android 5. I would guess the 4gb ram is a mistake.
[Thinkpad Tablet General] Masterofmichou:
Ok so I received it and YES it is 4go RAM 64go ROM and android 6.0 as anounced !

I found it on the french website of Lenovo, maybe it is not avaliable yet in other countries...

Concerning the root, I don't know yet : I started the tutorial, unlocked OEM and USB, installed ADB (and ADN installed some drivers), BUT when I go in the fastboot mode and type "fastboot oem unlock", it just type "wait for device" and that's all.

I know it should be a driver problem and tried to install google drivers via ADB driver installer, but it said that drivers were already installed. The device is recognized in normal boot, but not in fastboot mode.

Do you have an idea ?

I already had this problem on the first tablet, but I don't remember how I fixed it...

Thanks in advance !
[Thinkpad Tablet General] joesnose:
Like you said it sounds like a driver issue.

While in fastboot issue commond....

fastboot devices

If there is no output then your tablet is not recognised and you will have to try some other driver.

Instructions can be found online to install minimal android sdk, that might fix it.
[Thinkpad Tablet General] Alan-B:
Hi,

If your Lenovo is not found in ADB, here is pilot him intel ADB

Hi again, connexion finally worked and I could install everything, but during the final restart I had the bootloader error 03 message. And this time, whithout and vol+/- option, it just restarted again, then blocked on the Lenovo logo during at least 15 min. So I uninstalled everything, locked the bootloader again and wont try again :) the new version is very smooth and I could not detect any lag of but for the moment, 4go RAM seems to have a great impact ! It would have been great to root it but I don't want to risk a brick since this configuration works perfectly.

Thanks again for your help and have a nice day !

[Thinkpad Tablet General] joesnose:
Good news M, nothing is lost.

I do remember first boot takes an age!!! I thought it wasn't working the first time I did it.
[Thinkpad Tablet General] Masterofmichou:
You mean, more than 15 min ?
[Thinkpad Tablet General] joesnose:
Probably not quite, but loooooong. Also one must use su 2.46 any higher and it hangs on lenovo logo like yours.
[Thinkpad Tablet General] Masterofmichou:
I used 2.46 as requested. Thanks for the advice but it think I'll stick to unrooted version for now :)

Hi,

In the finale the rooot works you it on the new YT3 more with 4G of ram and 64 G internal ?

NB: this version Knows how to read Exfat ?
[Thinkpad Tablet General] palsedo:
Help :(

First of all hello. I´m a new Member :)

I did something stupid, don´t ask me how i did this but i flashed twrp on my yoga tab 3 pro (YT3-X90F) Android 6.0 and deleted the OS. At least twrp says so if i want to boot in system. I could give you more information, if my englisch would be better. I hope i can install the stock firmware via twrp. But to do this i need the right firmware but i can´t find it anywhere. Its the YOGA tab 3 pro with 4GB ram and 64 gb storage, i haven´t got the buildnumber..

And by the way, i made a backup with twrp but it looks like its broken, definitely it doesn´t work.

I hope my tab is not fully lost.:confused:
[Thinkpad Tablet General] joesnose:
Well there is 2 options.

1. Flash someone's twrp backup from lollipop and hope it works.

2. Ask masterofmichou (he posted just a couple of posts back) to load up twrp and make a backup and upload it somewhere for you.

Wait I just realised you made a backup, can't you restore your backup?

Option 2 is definitely the best option. And don't do any other crazy things to your tablet.
[Thinkpad Tablet General] Alan-B:
Hi,

Hello, As users can on the new version you will probably have to wait for a backup of this version !

Wait to know if the root works on this version before changing my version and take the new one

NB: The version TWRP 2.4.6 is it compatible with Android 6.0.x?
[Thinkpad Tablet General] Alan-B:
Hi,

You could have passed him root? And use TWRP?

(Ai putea cheltui Root? și de a folosi TWRP?)
[Thinkpad Tablet General] megatooth:

I have twrp 2.8.7 on my tab, yoga tab3pro 6.0 build. But i will wait. My tab won't walk away ;D
[Thinkpad Tablet General] Alan-B:
Re ...

The root worked? Or not?

You have Wifi, or WIFI/LTE ?

NB:

I will change with this version in LTE, but only if the root works?

There are no users who confirms that the root is good on this model!
[Thinkpad Tablet General] palsedo:
root didn't worked, got stock at lenovo logo for hours. I've got wifi so the x90f.. no lte.

First of all i want to be able to use it again, with or without root
[Thinkpad Tablet General] Alan-B:
Re hi,

The problem is that there is no way to have a Roma stock to be installed with Fastboot!!

There is maybe way to install a backup of 5.0.1 temporarily (without the part boot and bootloader)? But it is not guaranteed!

To hope that another user manages to make a good backup for you. !!
[Thinkpad Tablet General] palsedo:
Hi,

why with fastboot? TWRP is working.

I think i won't touch it anymore until there is a 100 percent working root. Then I'm gonna flash the recovery again and hopefully get a clean backup for my tab.

But thanks
[Thinkpad Tablet General] Qcraft:
Thanks, it works perfectly ?
[Thinkpad Tablet General] megatooth:
I have the latest version with 4gb ram and Android 6.0 out of the box. I tried rooting it and it just won't start. It's stuck at Lenovo logo.

Next I tried to restore the backup with TWRP but it always fails at ~90% with extract tar fork error 255. After this, if I try to reboot it is stuck at the Intel logo.

Should I try to lock the bootloader?

Can somebody help me to make it working again?
[Thinkpad Tablet General] Alan-B:
Hi,

The intel logo shows "BOOTLOADER ERROR CODE 03" ?

It is the unlocked bootloader which puts this error. Power Up makes restart ! (to YT3-X90 2 g ram that's ow)
[Thinkpad Tablet General] Qcraft:
Try pressing the volume up key a few times and let it reboot multiple times and see what happens

Well the stock firmware is posted somewhere in this thread but if you are not tech savvy probably best not to try!

You could always install aptoide until you have a better understanding of things.
[Thinkpad Tablet General] mike240se:
Would rooting help debloat it a little bit? I just got one as a x-mas gift and I love it but the lack of ram combined with something sucking up the little bit it has really ruins it. I have a 2gb samsung tab that has no issues but on this lenovo yoga 3 pro I got it is constantly killing apps to try to free up ram i guess. For example, I cant even listen to music while browing the web, it will kill the music app in the background all the time. Same thing with a screen dimming app I use, it constantly kills the screen dimming app which blows up my eyes. Sometimes it even kills the web browser when I view a page with a lot of stuff (like reddit page).
[Thinkpad Tablet General] joesnose:
Hi. The tablet is so sluggish its insane!!!

Always first, MAKE A BACKUP IMMEDIATELY!!!!!!!!!!! TWRP is your best friend when things get screwed up.

If you run your tablet unencrypted it will definitely help. Mine went from being practically useless to completely satisfactory.

Be warned to run unencrypted your tab will be factory reset: complete data wipe, instructions can be found in first post.

Also if you root your tab you can freeze or uninstall apps using programs like titanium backup. Make sure you have a twrp backup of course.
[Thinkpad Tablet General] mletchworth:

[Thinkpad Tablet General] Frenchdroid:
My YT3 Pro has been running really sluggish and I only just noticed that the data is encrypted (I was running unencrypted with root for ages). How has it reset to encrypted on its own ?

Do I just do what I did before to encrypt it again ? And I forgot if Titanium backup will work or not. Anyone know?
[Thinkpad Tablet General] joesnose:
I don't know why your tablet has encrypted again, as I remember you have to wait as it boots and tells you it is encrypting! Lol

I think titanium should work.

Remember that the in encryption script will wipe all data.

If you have a recent twrp backup, you could apply the script then restore your backup.

In fact if you have a backup with bootloader already modified, you wouldn't have to run the unencrypted script.

Any chance we can get the following disclaimer or something like it in big red letters at the top of the OP?

These methods only work on the original YT3-X90 series with 2GB RAM and z8500 CPU. Lenovo "refreshed" this series with 4GB RAM and a new CPU around November 2016, without changing the model numbers, and these methods WILL BRICK those devices.

Hi everyone! I wanted to know how I could do a raw dump of my lenovo that I would flash with fastboot. I'm kinda getting confused with all the informations I find on google. Thank you
[Thinkpad Tablet General] joesnose:
[MENTION=7459087]Chookass[/MENTION] I do have the script somewhere to make a raw dump, not sure where it is. I will take a look later.

Alternatively [MENTION=4696121]Shug69[/MENTION] do you still have a copy of the script that you can give to chookass?
[Thinkpad Tablet General] Shug69:
My files from that stage are a mess I'm afraid. Can find the dump files but not the script.
[Thinkpad Tablet General] joesnose:
Well I shall see if I can find it.
[Thinkpad Tablet General] Shug69:
In other news.. I dropped my tablet on the floor recently (there was alcohol involved).

It's not the sort of damage that's repairable.

After a few days of pondering I ordered the 4gb version (also alcohol involved). Right now I'm not sure which incident I regret most. Hoping the new tablet is more like the one. I thought I was buying last time☺
[Thinkpad Tablet General] joesnose:
[MENTION=729181]shug[/MENTION] lol. From what I understand there is no root yet on the 4gb version.
[Thinkpad Tablet General] Shug69:
Yeah. Saw that. Could live without it but if twrp is working then we're halfway.
[Thinkpad Tablet General] Taosaur:
Haha, there was a bit of alcohol involved when I hit the BUY button on the new Pro, too :o

Overall, I'm pretty happy with it, and only missing root because I can't ditch one or two apps I don't like. Performance has been solid - not 100% without hiccups, but solid. I've been gaming on it a fair bit, using the projector and speakers for a TV, read several graphic novels, and fallen down the reddithole in RIF a few times. My worst complaint is I haven't found a decent remote to use with the projector. Android-to-Android remotes are pretty underdeveloped, and most streaming apps aren't too remote-friendly.
[Thinkpad Tablet General] Shug69:
Got mine this morning. Unlocked it and made/restored backup of system with twrp. Cant find working su zip to flash though. Systemless versions do nothing and binaries that install to system soft brick it.
[Thinkpad Tablet General] joesnose:
[MENTION=4696121]Shug69[/MENTION] have you tried this?

From TWRP and booting it, go to*Advanced*-*Terminal*and enter:

echo SYSTEMLESS=true>>/data/.supersu

And press Enter, then exit. The spelling and spacing must be exact or it won't work. Then go to the main menu of TWRP and flash SuperSU normally, you should see the script specifically state it is doing a systemless install and patch the boot image (and in your case, cleanup an old standard root installation).
[Thinkpad Tablet General] Shug69:
No joy. I thing I need a newer version of twrp to implement patching in sepolicy. At least that's where it fails.

Try more stuff tomorrow . Haven't lost anything and i'm backed up.

[Thinkpad Tablet General] Shug69:
Yeah I saw that but it doesn't work unfortunately. Haven't tried unencrypted script (the tablet is unencrypted by default!). At this stage I'm convinced it's a twrp issue. I have several versions from testing before and only one of them will even load. Personally I don't think I want root enough to learn to build a new one. I had removed root from the old tablet because it broke my TV providers mobile app. Pleased with the tablet though. Ram makes a big difference- proper multitasking and good performance.

Good to hear. I am meant to have one next week. But I however do want root so I shall carry out some more investigations should it arrive.
