EDIT: No problem - I eventually figured out USB drivers weren't installed properly and I installed PDA Net which did them properly.

Just as another point though, my device didn't reboot at point 6 after saying YES to unlocking bootloader.

--------------------------------------------------------------

Thanks for the extra pointers. Unfortunately, I've run in to another problem.

I installed the 15 second ADB thing you linked but at the crucial moment, I get "waiting for device" and it goes on forever.

I've checked that I have USB debugging enabled, and OEM unlocking is enabled.

The weird thing is, when I run the command window when the YT3 Pro is in fastboot mode I get nothing from "adb devices" but when I do a normal boot (from fastboot) and then type "adb devices" the YT3 Pro is listed.

Any ideas please ?

Sorry. Me again. I backed up the bootloader too. Was that right ? Just the bootloader, system and recovery ?
[Thinkpad Tablet General] joesnose:
when you installed minimal adb and fastboot did you install it system wide?

And what happens if you issue the command " fastboot devices "

Edit. [MENTION=3619547]Frenchdroid[/MENTION] .Sorry I just noticed your edit. All sorted?
[Thinkpad Tablet General] Frenchdroid:
I'm all good now, after waiting for some epic startup times. I also had it boot loop a few times at the boot error screen but it eventually got past that.

Unencrypted data too but will take a while to see if that changes anything.

Definitely need to get titanium backup on there to save time setting up apps again.

Is there anything that can avoid going through the lenovo startup stuff ? And would titanium backup help in getting system settings, preferences and wallpapers back just how I had them ?
[Thinkpad Tablet General] joesnose:
Glad you sorted it now.

At the moment there is no way to avoid the error screen when running unencrypted as it relies on Patching the bootloader.

I think titanium can back up those system settings but not sure. And if an ota comes you can preserve data using instructions in post 3 of this thread. I think that will keep all those settings intact, but again I am usure so always best to try and back them up using titanium.
[Thinkpad Tablet General] Frenchdroid:
Hi Samiej . I took a look at lurkers post about running microSD exFAT and wondered if you'd be willing to post a few basic steps to get this working as I found the details a bit esoteric? Is it something that can be done once and forgotten about? Thanks in advance.

On a general note, I'm really happy with the yoga tab 3 pro rooted and unencrypted - mainly for just being able to get rid of ads and to run a few apps.
[Thinkpad Tablet General] gaurika:
Guys, thanks for your work.

As I've seen in previous topic, factory system image backups for YT3-X90L were requested (as they were only available for F version).

If still needed, please let me know (along with what you need specifically from my side) and I will gladly help! :)

Below specs for my tablet:

- model number: YT3-X90L

- Android version: 5.1

- Android security patch level: 2016-01-01

Hi

I need factory system image backups for YT3-X90F.

All I can find is support.lenovo.com/us/en/products/Tablets/Yoga-Series/YOGA-TAB-3-Pro-10

but the archive seems to be incomplete. There are no folders which are mentioned in readme.
[Thinkpad Tablet General] joesnose:
hello kovtun77. what's the issue you are having?
[Thinkpad Tablet General] kovtun77:
I played with rooting without backups and now my device battery shows 0%.

Also all sensors are off.
[Thinkpad Tablet General] joesnose:
Still have bootloader unlocked?
[Thinkpad Tablet General] kovtun77:
Yes, I have complete access - adb, fastboot and twrp.
[Thinkpad Tablet General] Lusanagi:
hi joesnose

I think this might be a bit dumb, but it caould work to emphasize the need to "fastboot format data" after installin the decrypt zip:

I installed it and forgot to do the format, now my tab has no write permissions to the "Download" (and I think others as well, I installed TB and it says it has no write access) and I think this also affects other apps to get write access on my sd card.

I'll format the data on my tab and update here regarding how it went
[Thinkpad Tablet General] joesnose:
Have you tried other apps?
[Thinkpad Tablet General] Lusanagi:
Yeah, and not even file browsers are able to write to the internal storage. I'm about to format (good thing I haven't installed many apps yet), I'll get back to you.

Edit: OK, that didn't work, now I only have the "Android" folder on the internal storage and when I try to download something in chrome it says it can't create the "Downloads" folder

Edit2: OK, I formated twice and still got the error, so I restored my backup (the configuration and apps I had when I made it did not restore, but I see SuperSU binary is not installed, so I guess it's all good) and then only installed the decryption zip and the storage has the folders created and I can download things now; I'll try to re-root again maybe tomorrow and see what happens.
[Thinkpad Tablet General] rfsteel:
What did you do to fix the USB driver error ?

I'm running Windows 10 and have installed the Lenovo USB Drivers, yet when I connect my X90F in Fastboot mode it doesn't find any drivers for it, nor can I manually install then from the Program Files (x86)\LenovoUsbDriver folder that is created.

Edit: Sorry just re-read your post correctly and installing PDANet has solved my issue also.
[Thinkpad Tablet General] KrIs86Bs:
Hello. For me, something does not work the method ... maybe I did not do anything wrong. Things to half of the steps they perform but point 5 only see what I get ... it does not recognize my device ... and is connected to the laptop ... what should I do now?
[Thinkpad Tablet General] s515:
hello <3

I did all the steps but I stuck in loopboot (bootloader error 03)

I restored my backup and my tab works again but with no root

I tried it 3 time but it is the same problem

is there any chance I can root my device

my tab is yt3-x90L

thanks
[Thinkpad Tablet General] joesnose:
What model do you have?

Easy driver installer linked in first post.
[Thinkpad Tablet General] joesnose:
Have you used the easy fastboot driver installer from first post?

Is your tablet in fastboot mode?
[Thinkpad Tablet General] joesnose:
So you load twrp and flash super user zip

reboot tablet.

Error code 3, press volume up for normal boot.

Reboots to error code 3?
[Thinkpad Tablet General] joesnose:
Just remembered something, make sure you use superuser 2.46!
[Thinkpad Tablet General] s515:
I installed the 2.46 version

And when I press volume up to normal boot , it back again to error code 03
[Thinkpad Tablet General] joesnose:
Strange problem, there are others with the L who this method works for.

When you flash the zip, twrp says success?
[Thinkpad Tablet General] s515:
Yes . Everything work perfectly

Except the last boot :(
[Thinkpad Tablet General] joesnose:
The only other suggestion i have is that some one with the L shares their twrp backup so you can try it.
[Thinkpad Tablet General] s515:
I wish someone will share it

Thanks for answering :good:

By the way I have the stock backup for yt3-x90 L

Mention me in case someone need it
[Thinkpad Tablet General] joesnose:
[MENTION=535343]all[/MENTION]

Anyone care to make a twrp backup of their rooted L variant and share it with [MENTION=7732832]s515[/MENTION].
[Thinkpad Tablet General] s515:
On more question :o

Should the fastboot OEM still unlocked when I finish the steps or should I lock it again ?

I wonder if I made a mistake
[Thinkpad Tablet General] joesnose:
I always advise to keep unlocked, makes recovery easier if something goes wrong.
[Thinkpad Tablet General] s515:
OK. But if I lost the recovery can I restore it again ?

I have the backup

And will it make sense if I locked it ?

Will the last boot work ?

So normally the device must be rooted with the fastboot OEM unlocked right ?
[Thinkpad Tablet General] joesnose:
to restore your backup needs twrp.

the oem unlock allows you to run twrp.
[Thinkpad Tablet General] KrIs86Bs:

I think it is in fastboot mode, but we do not again ... Look at the picture ...

My model is: Lenovo YT3-X90L
[Thinkpad Tablet General] joesnose:
That is fastboot mode:)

So on your PC you need to reinstall the fastboot driver, it should show up in device manager as Intel device.

The easy installer is linked in first post.
[Thinkpad Tablet General] KrIs86Bs:
All right. I reinstalled it, but my laptop has Windows 10 and read in the Changelog 15 seconds ADB Instaler: Version 1.4.2 - Updated adb and fastboot to API 21 version (Android 5.0) - My tablet is just running Android 5.1 and it will be appropriate version, but I will put into the subject ... there is only the latest 1.4.3 .... maybe there is a problem ... and the description shown in the video How to Install / Fix Fastboot Drivers in Computer Managment - > Device Manager can not find anywhere Other Devices -> Android ... provided that the tablet is connected via USB to my laptop ... what to do ... help me! :crying::crying::crying:
[Thinkpad Tablet General] joesnose:
Its the one showing up as mtp.
[Thinkpad Tablet General] KrIs86Bs:
YES. Perfect! Well ... I was able to fix driver as a video and here's what I get (pictured bellow) ... we are back to point 5 of the description and still does not recognize my tablet ...
[Thinkpad Tablet General] joesnose:
That's how mine looks.
[Thinkpad Tablet General] KrIs86Bs:
I could not understand after giving this error: bootloader error 3 What should I do to make my turn tablet in normal mode ... would you help me because it constantly resets and stands only in this mode error ...
[Thinkpad Tablet General] joesnose:
Press volume up for normal boot?
[Thinkpad Tablet General] KrIs86Bs:
Press it and I appear this Image and pressed the power button again to me shows bootloader error 3 ....
[Thinkpad Tablet General] joesnose:
Sorry for the silly question! Are you sure you are pressing volume up? The fastboot screen usually shows up when volume down key is pressed.
[Thinkpad Tablet General] KrIs86Bs:
After several long press starts ... now I consider that my tablet is root?
[Thinkpad Tablet General] joesnose:
Is your tablet booting now?

Did you load twrp and make a backup?
[Thinkpad Tablet General] KrIs86Bs:
Starts are normal, but restart again gives me this error and volume up resets to normal mode ... I do not know how to do backup twrp ... share my
[Thinkpad Tablet General] joesnose:
You will receive error 3 every boot, pressing volume up should then continue normal boot.

You are not rooted you have just unlocked the bootloader.

Now you need to load twrp and make a backup.

Just follow the instructions in first post.

Have you ever used twrp before?
[Thinkpad Tablet General] Kris86bs01:
Have you ever used twrp before? - No...Help me.
[Thinkpad Tablet General] Kris86bs01:
Soryy It does not allow me to send more emails...After Backup is Complete, to press the button you Reboot System or Back?

....It was no longer a line and pushed Reboot System otherwise have installed UPDATE-SuperSU-v2.46
[Thinkpad Tablet General] joesnose:
You can use root checker from play store to check.
[Thinkpad Tablet General] joesnose:
Well folks, my tab has died!!! Damnit!!!!
[Thinkpad Tablet General] mletchworth:
That really sucks man. Sorry for your loss. Are you gonna replace it?
[Thinkpad Tablet General] joesnose:
Not with another tab 3 pro. Lol

Only bought it last December, so it hasn't even lasted a year!!
[Thinkpad Tablet General] joesnose:
She lives!!!!!

Had it on charge for three days! Charging light and vibrate would come on for a second every three mins or so and if I tried to hard reset the same charge light and vibrate for a second.

Just tried to turn it on twenty times in a row and it finally booted and is at 56% battery!!!!

Thought it was all over, lol . sorry for the dramatics!
[Thinkpad Tablet General] mletchworth:
This tab has so much potential, but the lack of popularity (aka development) and really poor processor controls and RAM management made it kind of a lemon.
[Thinkpad Tablet General] joesnose:
Well price has a lot to do with that I guess. Marketed more toward business, though I don't think it even fits that market.

But indeed a shame there's no real development.
[Thinkpad Tablet General] joesnose:
Spoke too soon!!! Lol

Hi I wonder if anyone can help me.

I've messed up my tab, X90F version. I no longer have my backup so am looking to restore from scratch. My bootloader is still unlocked and I can get into twrp. Can I just restore the backup shug uploaded??

Failing that how can I get back to fully new? I've flashed my Nexus 6P using system.img, recovery.img etc. Can I do this with the Lenovo Yoga Tab 3 Pro, if so where are the files?

thanks for any help
[Thinkpad Tablet General] joesnose:
Hi jbaggs, shug69 posted links to both a twrp backup and the system IMG backup. Sorry I can't remember the post numbers but they are around the same place.
[Thinkpad Tablet General] jbaggs:
Hi Josenose thanks for the fast reply! Appreciate it. I found both the pages 15 &29 I believe however having downloaded both they seem to be the same thing (the official restore with details on how to restore using the run_me file)

I have done this method at all seems to go through ok and the it reboots and has stayed on the same screen for the last 20mins. There's nothing on the screen but it has lit up, if that makes sense?

How long should the first boot up take? Thanks for the help
[Thinkpad Tablet General] joesnose:
Any more joy? First boot takes ages but usually shows lenovo logo.
[Thinkpad Tablet General] jbaggs:
It didn't do anything for 45mins so I booted into stock recovery and wiped cache and reset setting's. Seems to have done the trick. Thanks for your help
[Thinkpad Tablet General] joesnose:
Glad to hear its sorted. [emoji1]
[Thinkpad Tablet General] Alan-B:
Hi,

you can install TWRP in rom 3.0.2-0 on Tab3 X90L ?

Or which version you can install in Rom ? (not temporary)

thank you in advance
[Thinkpad Tablet General] joesnose:
The only version at the moment is the one included in the first post 2.8..... I think.

Can be flashed to tablet.
[Thinkpad Tablet General] Alan-B:
Hi,

Ok Thank you.

I managed to make a complete known backup SD.

But since the error message 3, I do not any more manage to use the commands fastboot!! The device is not any more recognized with Fastboot devices

An idea of why ??
[Thinkpad Tablet General] joesnose:
From error 3 pressing volume down should take you to fastboot
[Thinkpad Tablet General] Alan-B:
Re... hi,

Has you he trick there to deactivate the sécure boot?

Or not possible to install patches with a file(case) app or priv-app !!!!
[Thinkpad Tablet General] joesnose:
Sorry I don't understand your question.

It is possible to disable secure boot, but it does make tablet show error 4.

Error 4 makes fastboot only available via button presses ( power and volume down).

What are you trying to do?
[Thinkpad Tablet General] Alan-B:
re.....

Secure-boot deactivate, it is to test a custom deodex rom, a rom of my compilation.

But, with secure boot enabled is not possible !!

How to modify the secure boot ??

(Just having the root not used much!)

NB: Désolé pour l'Anglais !!
[Thinkpad Tablet General] joesnose:
Your English is very good!

To disable secure boot you must enter the bios.

****Attention***** entering the bios is dangerous!!! Changing the wrong option can break your tablet!!! (presse-papier)

I take no responsibility for anything you do there [emoji1]

To get into the bios....from twrp select bios.

I am sorry my tablet is broken now and I can't remember the exact location of the secure boot option.

As I remember in the bios, power button is enter, volume up and down to navigate and long press of one of the volume buttons is esc/back.
[Thinkpad Tablet General] Alan-B:
Hello,

Here is a complete backup of stock, not deciphered and with the bootloader and recovery eccentric

NB: When she is root it is not simple to switch on, or power off !

It always goes back by the message 3 :( Several manipulations are always needed :(

Anybody did not find a solution? And a script to have ' secure boot deactivated ' ?

Edit: I had a problem with my battery, but it turned out to be a hardware problem fixed on warranty. Removing potentially misleading posts.
[Thinkpad Tablet General] joesnose:
Well mine the screen doesn't even light up! The tablet vibrates, led lights up for a second then nothing. Same if I just leave it on charge, every 45 second or so vibration and led then nothing.

The time I said she lives, after multiple, yes MULTIPLE!, attempts at boot.

Came on once and reported 56%! When I looked again after 30 seconds or so it just had ! In the battery icon.

So almost certainly a battery issue!!!!
[Thinkpad Tablet General] heavy_robby:
Same error happened to me! :crying:
[Thinkpad Tablet General] joesnose:
I think shug69 posted a link to the backup that will possibly help you. Post number 145 it is for the F varient I believe.

If you have the L variant then someone else has that backup....can't remember who.

But these backups can get past the locked bootloader problem.

Just leave bootloader unlocked. :)
[Thinkpad Tablet General] heavy_robby:
My model is Lenovo YT3-X90L Android 5.1

In Developer Options "OEM unlocking" turns on disabled every time i reboot in fastboot mode. I think this is the problem. What can I do? I want to unlock the bootloader to continue rooting my tab
[Thinkpad Tablet General] joesnose:
Turn on oem unlocking reboot to fastboot and issue comand ....

Fasboot oem unlock

It is normal for.the oem unlock to reset after.reboot.
[Thinkpad Tablet General] heavy_robby:
FAILED (remote: Unlocking device not allowed)

Lock state=Locked when reboot to fastboot mode after setting OEM unlocking in Developer Options
[Thinkpad Tablet General] joesnose:
Device will still be in locked state , the developer option just allows the unlocking.

With tablet connected to pc in fastboot issue...

fastboot devices

should list your tablet, if not problem is with your installed fastboot.
[Thinkpad Tablet General] heavy_robby:
fastboot devices list the tab correctly
[Thinkpad Tablet General] joesnose:
Strange. are you using the fastboot linked in first post? That has worked for most.

After every reboot you will have to retick allow oem unlocking.

With that ticked, reboot straight to fasboot and issue command. Not sure why this is not working for you!
[Thinkpad Tablet General] heavy_robby:
Yes, of course, the only that wored for now (other guide and programs and drivers never worked until I found this thread)
[Thinkpad Tablet General] joesnose:
And you are definitely in fastboot mode while issuing the command?
[Thinkpad Tablet General] heavy_robby:
finally done it! for some reason another fastboot was in all-path like mode, just typed the command with his extension and worked.

Now, I am taken by the excitement I did not back up and installed supersu -_-

I'm now in bootloop with error code 3, can I do anything?
[Thinkpad Tablet General] joesnose:
Can you get to fastboot?
[Thinkpad Tablet General] heavy_robby:
Yes (and now lock state is unlocked)
[Thinkpad Tablet General] joesnose:
Well unlocked is helpful.

Not making a backup is not. Lol

So if you select normal boot from fastboot screen just brings you back to error 3?
[Thinkpad Tablet General] heavy_robby:
yes :(
[Thinkpad Tablet General] joesnose:
Well if you ask someone here who has the L variant to share their twrp backup with you that should get you up and running, you could restore from twrp.

can someone upload their backup for robby. Or link to an already uploaded backup. Preferably twrp backup

L variant only please.
[Thinkpad Tablet General] heavy_robby:
I don't know how to thank you, is this http://xdaforums.com/showpost.php?p=68090723&postcount=268 helpful? The process to restore this image is to boot (flash?) the file with fastboot when the device is in fastboot mode?
[Thinkpad Tablet General] joesnose:
No ,copy it to external sdcard.

from fastboot follow instructions in first post to boot twrp.

Restore the backup from twrp.
[Thinkpad Tablet General] heavy_robby:
Ok, Android's God have an issue with me. TWRP can't find the backup. I have to put it in a specific directory?
[Thinkpad Tablet General] joesnose:
Yes, can't remember what it is though

Put at root of sdcard

TWRP/BACKUPS/

put it in there and try again. There may be another folder needed in BACKUPS but someone with the yogatab will have to tell you what its called.
[Thinkpad Tablet General] heavy_robby:
finally done it! Restore succes, but once reboot the sistem, again bootloop error code 3
[Thinkpad Tablet General] joesnose:
When you unlocked your bootloader were you prompted that it would format data?
[Thinkpad Tablet General] heavy_robby:
Yes

---------- Post added at 08:37 PM ---------- Previous post was at 08:34 PM ----------

I tried to lock again bootloader, and now android is configuring as if it were a new product (I think this is because the restore to a stock backup). It takes many time to verify information after google account login..
[Thinkpad Tablet General] joesnose:
So you locked bootloader and it booted straight away?
[Thinkpad Tablet General] heavy_robby:
yes, with no problem. But with root checker says to me that the device isn't properly rooted :\
[Thinkpad Tablet General] joesnose:
So you restored, flashed supersu and locked bootloader and now root is broken?
[Thinkpad Tablet General] heavy_robby:
Finally works! All functional! Thank you so much!!!

(I've done all the passage again, on bootloop code error 3, just locked oem and the device works perfectly)
[Thinkpad Tablet General] joesnose:
No worries. One question, if you unlock your bootloader you still get boot loop?

I only ask as recovery is easier with unlocked bootloader as one can just load twrp and flash.

There is a way to recover on locked bootloader but a different backup is needed, I think user [MENTION=242772]coi[/MENTION]tin has it. Might be useful to aquire it as the more users that have it the more people can help with problems.
[Thinkpad Tablet General] danjac:
hi there,

might this also work for the new lenovo yoga book which has the same intel soc.

i've already tried to boot the recovery mentioned in the first post, but unfortunately it didn't work and booted the nornal system instead.

any help to gain root would be appreciated.
[Thinkpad Tablet General] joesnose:
I doubt it will work. Would need more similarities than just the chip, screen resolution for instance.

Also have you unlocked your bootloader.
[Thinkpad Tablet General] Anil Malhotra:
Thanks so much
[Thinkpad Tablet General] danjac:
yes, of course I unlocked the bootloader. do you have any idea if one could adopt the recovery to fit the yoga book?

on the other hand, will such a 'live session' still be possible with marshmallow - because i came across this other quite similar method (see thread) and it seems like it doesn't work for android 6 anymore.

thanks for your help and sorry for being slightly off topic!
[Thinkpad Tablet General] corti96d:
I can't see my Yoga Tab 3 Pro in fastboot devices. I see my device in ADB device list when the tablet is on, but when I reboot it in fastboot mode, I can't see it!
