In android settings.

Go to about tablet.

Tap build number 7 times.

You are now a developer! Lol

Go back to settings

Find new option for developer settings

Enable allow oem unlock

Reboot to fastboot

Try again.
[Thinkpad Tablet General] mlst1:
Hi Joesnose,

have the same problem...silly am I.

Bootloader locked and no way in any more...to unlock again.

Could you please help me? I habe th YT3 Pro X90L (LTE )

Thanks in advance

Best Michael
[Thinkpad Tablet General] joesnose:
Well I am afraid I don't think anyone has made a dump for the L!

what's your issue exactly?
[Thinkpad Tablet General] mlst1:
I unlocked bootloader and booted twrp, flashed the data unencryption img... as described in the first post

everything worked smooth and fine

then i had to bring it back to factory condition for service.

back from service i wanted to unlock and unencrypt again...and forgot to enable oem-unlock option in setttings.

Thats where i´m now.

I have an twrp backup from the original image but can´t boot to twrp any more....thats the misery
[Thinkpad Tablet General] joesnose:
And you have bootloop? Or you can get to android?
[Thinkpad Tablet General] mlst1:
I have kind of a bootloop. Instead of Error 03 i now get error 01 at every boot and it says bootloader is defective....Vol+ send me to recovery mode Vol- shut down (but restarts).....

When pressing Vol+ and Vol- plus PwrButton i get in a mode, that i didn´t know before "XNA fastboot Mode" it says in very small letters. In this mode the tablet is recognized by fastboot commands. BUT

when executing any fastboot command you end at the Intel Bootloader error 01....
[Thinkpad Tablet General] joesnose:
sorry for my late response, in post #188 xamul said he used the recovery from the N variant and it fixed his problem.

so possibility to try bootloader from another variant, better if someone here with the L could dump theres.
[Thinkpad Tablet General] emilgeorge1234:
Is there any way to gain warranty back after decrypt or root? Do u think any chance of any custom ROMs with projector working in future?
[Thinkpad Tablet General] joesnose:
I think if you restore your backup and relock bootloader it should be stock, but I might be wrong!

as for the custom roms, it doesn't appear to be much of a modders tablet.
[Thinkpad Tablet General] hegemnon:
Hello joesnose.

Do you have solution for better multitasking in Yoga tab 3 Pro? Is switching between apps better after unecryption?

They are killed very fast, too early I think. I have still enough memory between 0,7 up to 1,2 gb (after running only two or three apps)
[Thinkpad Tablet General] joesnose:
All I know is it works after decryption, before that I had serious lag and frequent freezes. Things seem to open up quite snappy.
[Thinkpad Tablet General] emilgeorge1234:
I was wondering if anyone could explain me why out of 2gig ram why only 300+mb available to application memory? That's what my kindle app says!! Thanks

Fastboot Oem Unlock

At step 5, after shift right clicking in the folder I extracted TWRP into in order to open that command prompt; I type in Fastboot Oem Unlock and it responds with waiting on device. I waited quite a long time and nothing happened.

I am in developer mode,

I have allowed debugging.

I have also enabled OEM unlocking.

Although I have noticed whenever I restart my tablet after hardbooting it because it wont respond to TWRP, I come back and OEM unlocking is switched off.

Specifically my problem is the waiting on device error
[Thinkpad Tablet General] manolito1998:
I assume you are using windows. You need to install fastboot/adb drivers. HERE they are. In my case they weren't installed automatically so I went to "Device Management" and right click over the unknown device, then I select "android composite ADB".

Cheers.
[Thinkpad Tablet General] joesnose:
[MENTION=7603792]Chasker[/MENTION] , this sounds like the best advice. Let everyone know if [MENTION=987953]manolito1998[/MENTION] s link helped.
[Thinkpad Tablet General] Chasker:
For some reason that did not work. I had already installed those drivers etc from the page in the directions. I woke up this morning after my computer restarted itself for an update and my yoga tablet finally appeared below unknown devices. I tried to assign the ABD driver I installed from that website, (which by the way says SAMSUNG Android root ABD root or something to that sort) and it failed to start. There were two versions, one that said it was from 2014 and one that said it was from 2012. I don't understand either of these dates because I made this computer in late 2015.

I deleted all unnecessary USB drivers and then reinstalled ADB under administrator. I then restarted my computer. I then plugged in my yoga tablet in FASTBOOT mode and it did not come up as an unknown device. I checked my USB devices and I saw something that said ADB. I tried to right click it and look for drivers but it said the only compatible driver was the one it was using, so I left it alone. I figured everything was working properly so I tried to FASTBOOT OEM UNLOCK again in CMD in the TWRP folder and it failed again with the same (Waiting for device) Error.

EDIT: I right clicked the icon for "Safely remove hardware and eject media" In my mini windows at the right of my start dock. I saw the model of my yoga pro 3 tab. above it, it said devices and printers. I clicked that. at the bottom of that window was an Unspecified section which lay my Yoga tablets model number. I right clicked it for more information and clicked properties. there are three drivers working currently as its plugged in fastboot mode. ADB interface. MTP USB Device. USB composite device. Thought that information may help.

This is frustrating to say the least.
[Thinkpad Tablet General] joesnose:
[MENTION=7603792]Chasker[/MENTION], mine shows up in device manager as intel adb device.

Are you definitely putting your tab in fastboot mode?
[Thinkpad Tablet General] Chasker:
well I hold the volume rocker when I turn it on and it goes to a really weird black screen with white writing in the top left with numbers designating different options. If its not fastboot its something weird for sure.
[Thinkpad Tablet General] Chookass:
Thanks for this forum and all the help I found here. For all those who have trouble using fastboot on linux (waiting for device etc. …) do not forget to enter the commands as root!!

chookass
[Thinkpad Tablet General] joesnose:
Sorry for the late response chasker, that is not fastboot mode.

[MENTION=7603792]Chasker[/MENTION]

Try booting in dnx mode, when tablet is off power on while holding both volume keyd, then on pc try

adb reboot bootloader
[Thinkpad Tablet General] cotin:
Any progress in getting the X90L rooted?
[Thinkpad Tablet General] joesnose:
I thought the process already worked on the L?
[Thinkpad Tablet General] cotin:
Oh, strange. I uploaded my bootloader since some had issues with the encryption removing and root on the L. Maybe i misunderstood.

When i tried the live session with twrp my device rebooted instantly after 2 seconds in the twrp recovery to show me the error code 3 screen. I had to do the adb fastboot oem LOCK to make it boot again. So i can't really do **** with 2 seconds in twrp. I used all the files provided in the rooting guide. First time i was in twrp i managed to make a backup of everything. And i restarted and tried to start the twrp live session again to root the tab and then the twrp didnt work anymore.

So im afraid to brick it since ive only found the firmware for the F. I dont know if the F works for the L since they have different hardware.

---------- Post added at 08:04 PM ---------- Previous post was at 07:31 PM ----------

Well since i have the backup i dont the the firmware, but i need twrp to work.
[Thinkpad Tablet General] joesnose:
So first time you got to twrp it didn't reboot?
[Thinkpad Tablet General] cotin:
It did reboot. But not to Android. Just got the error code 3. And then i trie de to start the twrp again from fastboot and then booted twrp and rebooted after 1-2 seconds. So i did the full back the first time i was in twrp. And the second time when i was going to root i were unable to do anything in twrp because it reboot right after the live session started.

I will see if i can make a video of this when i try again tomorrow.

---------- Post added at 10:49 PM ---------- Previous post was at 10:47 PM ----------

Think i will go with the removing of the encryption this time. IF i get in twrp this time :laugh:
[Thinkpad Tablet General] cotin:
Ok, so now i tried to remove the encryption by booting twrp successfully, i did the backup without data since the data was wiped by the "fastboot oem unlock"

After the backup in twrp went fine i ran the x90-disable_encr.zip and tried to delete data after, that did not work since the data was wiped by the "fastboot oem unlock" now it got me to the error code screen and did a fastboot format data just to be sure. and tried to "START" from the error code 03 screen.

Now my tab is on, but with a black screen and at my computer this pops up: CD Drive (G:) Lenovo_Suite

The screen on my X90L is still black after 20 min. And what do you know! Now it is on! :D Let's double check that encryption is removed!

And the encryption is gone! :) THANK YOU VERY MUCH.

I have no idea what went wrong the first time. But now it works.

Wow im really going to love my new smooth and more responsive YOGA tab 3 pro <3
[Thinkpad Tablet General] joesnose:
Brilliant, well pleased you managed.
[Thinkpad Tablet General] cotin:
Is it possible to lock the bootloader after removing the encryption? I have not rooted.
[Thinkpad Tablet General] joesnose:
Not actually sure as bootloader is modified in order to allow decrypted data, but I would suggest always leaving the bootloader UNLOCKED as it makes recovering tablet easier.
[Thinkpad Tablet General] cotin:
You mean unlocked, right?
[Thinkpad Tablet General] joesnose:
Hell yes!!! Thanks
[Thinkpad Tablet General] cotin:
Great :D
[Thinkpad Tablet General] cotin:
Any hope for a custom rom coming to YT3P with a working projector? Or even an installable twrp?

---------- Post added at 03:21 PM ---------- Previous post was at 03:20 PM ----------

Sorry, did I just go off topic?

---------- Post added at 05:03 PM ---------- Previous post was at 04:21 PM ----------

And also if i want to root it now that i have removed the encryption. Will it be encrypted again after i delete data to proceed with the rooting process?

And do i really have to delete data to root it?
[Thinkpad Tablet General] joesnose:
[MENTION=3008044]cotin[/MENTION]

Well, I have twrp installed, I just flashed the version from the first post but obviously make sure you have a backup of your original!!!

And if you are already oem unlocked and data unencrypted then root should not wipe data.

And for custom roms we shall have to wait for someone to port or build a rom for our device, out of my scope I'm afraid.
[Thinkpad Tablet General] cotin:
Please tell me how you installed twrp on the tab! I hate this live session stuff.

---------- Post added at 06:34 PM ---------- Previous post was at 06:12 PM ----------

Just start the live session with twrp and make backup of the recovery, then flash twrp with Odin?
[Thinkpad Tablet General] joesnose:
[MENTION=3008044]cotin[/MENTION]

Indeed start a live session and make a backup of your stock recovery, you should have made a backup already but you may not have included recovery! So yes make a backup.

No need for odin, that's for samsung I believe. Simply.....

Instead of - fasboot boot twrp.img

replace with - fastboot flash recovery twrp.img

Replace twrp.img with the name of your .img file
[Thinkpad Tablet General] cotin:
Thanks! :D

What

---------- Post added at 12:11 PM ---------- Previous post was at 12:03 PM ----------

ONE more thing :D After remvoing the encryption with allow unlocking bootloader from the settings. Do i have to "allow unlocking bootloader" in the setting again before i flash twrp?
[Thinkpad Tablet General] joesnose:
[MENTION=3008044]cotin[/MENTION]

No, once bootloader is unlocked it stays unlocked.

Backup YogaTab 3 Pro L ?

Hi everyone.

Due to some issues I've lost my twrp backup.

My device was soft bricked, I used the image for YT3P found here, which worked pretty fine.

Though I lost the 3G which is particularly usefull fos me =/

Is there any solution?
[Thinkpad Tablet General] joesnose:
You probably need a backup from the L variant. What did you flash?
[Thinkpad Tablet General] Chookass:
Yes exactly !

I want the L variant!

I flashed the version posted by [MENTION=4696121]Shug69[/MENTION] on the 18th April 2016 whichi is the X90P.

I can confirm alongside with [MENTION=7517306]xamul[/MENTION] that it works well on the L hardware

But, obviously I lost the 3G
[Thinkpad Tablet General] joesnose:
I think maybe [MENTION=3008044]cotin[/MENTION] has a link to the stock L firmware, you should ask him.
[Thinkpad Tablet General] Chookass:
I would be great!

How can i invoque him? This way? [MENTION=3008044]cotin[/MENTION] [MENTION=3008044]cotin[/MENTION] [MENTION=3008044]cotin[/MENTION]! =D
[Thinkpad Tablet General] joesnose:
Lmao.
[Thinkpad Tablet General] cotin:
Hey yeah i have the stock rom for the L. I'll just ZIP it all together and upload it to my drive.

But i dont have the recovery because i got distracted and flashed twrp before i could make a backup of the stock recovery. And twrp wont even start after i flashed it. And the stock recovery is gone. So i basically got NO recovery at the time. But i have everything else.

All i ask in return is your backup of the stock recovery if you have it!

Will upload the files soon.

iT seems that there is a problem with the sharing… or do I do something wrong?

I flashed everything with the zip file of [MENTION=2195656]joesnose[/MENTION] and [MENTION=1128975]ionion[/MENTION]i I guess I dont have much left!

Though if I can do anything to help!

---------- Post added at 02:04 PM ---------- Previous post was at 01:33 PM ----------

It works now!! Thanks =D

Let me ask because I m not sure I understand the terms…

1) Stock firmware significate the image of the disk as provided by lenovo, right?

2) You made an image of all partition but forget to do the one of the recovery partition?

3) The recovery partition is used to reinitialise the tablet using a software from lenovo?

4) When you flashed twrp, it deleted this partition? Why?

5) Also this partition is not really important since we can flash everything by hand, right?

Sorry for all this question, but even if I think I understand the most, all this details stay confusing for me…
[Thinkpad Tablet General] cotin:
Well, i have the recovery partition. Just not the stock recovery. If you want i can give you the backup of the twrp recovery i have installed. I messed up and forgot to backup my recovery as Joesnose clearly told me to do before i flashed it. But i have a recovery that works. And i havent used stock recovery all my life. maybe one day that i need it but i hope that someone has a backup of stock recovery to share by then.

Want me to upload my twrp recovery? Or can you flash it via ADB fastboot?
[Thinkpad Tablet General] joesnose:
Does the stock rom you are sharing not include a stock recovery?

You will need the stock recovery should an update come for our sorry tablet! The update would probably brick without stock recovery present.
[Thinkpad Tablet General] cotin:
1) Sadly i dont think Lenovo provides the stock firmware. So the ones that can help us is the gang from XDA.

2) i dont have the stock recovery anymore

3) Yes. It is supposed to be.

4) When i flash another recovery it deletes the old one because you can only have one recovery installed

5) Yes.

I might be off a little bit about the answers but i think im pretty much right. [MENTION=2195656]joesnose[/MENTION] ?

---------- Post added at 07:05 PM ---------- Previous post was at 07:00 PM ----------

Do you have the stock recovery for us?
[Thinkpad Tablet General] Chookass:
Those are the question XD

What is the difference between recovery and stock recovery?

what is recovery to begin with? xD

NB : i didn't received yet your archive (slow conection + errors = still 1 hour of downloading)

I have already done the method of the archive of Joesnose and Ionioni which use a lot of " fastboot flash …" commads. It was sufficiently straightforward for me to adapt it on linux!

But I don't know how «recovery partition» or «stock recovery» is.

I found this http://xdaforums.com/wiki/Recovery and I understand that is the program I get to when i use vol+?

If it is that, I flashed it with the version provided in the archive of Joesnose and Ionioni for the P version, and it works well without noticeable difference on the L one.

The only difference I observed when flashing the P version on the L is the disapearing of 3G related options!
[Thinkpad Tablet General] joesnose:
Is it not included in that rom file you have?
[Thinkpad Tablet General] Chookass:
twrp is a recovery partition in fact?

Thus installing twrp remove the recovery of lenovo?

If I had knew all this at the beginning I would have make an image everything before doing the root… Though I don't know how to do it %)

[MENTION=2195656]joesnose[/MENTION], maybe a solution would be that you edit your first first post of this thread to say to make an image of the partitions *before* going twrp and to also make the request of those images to for the X,L and even P version (since the one we got here has already been updated by Lenovo)?

My two cents…

---------- Post added at 05:17 PM ---------- Previous post was at 05:14 PM ----------

If you are asking me, I instaled TWRP long ago and recently I flashed *all* partitions using the file provided by the archive of the YT3P

To be clear, on DNX mode, I entered the command

fastboot flash recovery recovery.img

where recovery.img has been provided by this archive
[Thinkpad Tablet General] joesnose:
That should be the stock .img
[Thinkpad Tablet General] Chookass:
Hanhan!

And installing TWRP did not affect it?

If so I can do it !!! >=]

But I don't know how ^^"
[Thinkpad Tablet General] joesnose:
Just keep a copy of the stock one, that's all you need.
[Thinkpad Tablet General] Chookass:
how do i do the copy?

this? http://xdaforums.com/showthread.php?t=2450045

---------- Post added at 06:11 PM ---------- Previous post was at 06:02 PM ----------

But it required to be rooted… but I understood you have to do the copy before installing twrp? thus I already installed twrp before flashing…

---------- Post added at 06:20 PM ---------- Previous post was at 06:11 PM ----------

Thanks, [MENTION=3008044]cotin[/MENTION] I succeeded in downloading!

Though is it flashed with "flashboot flash …"*?

Why does it have two "system" partitions?
[Thinkpad Tablet General] joesnose:
I do.t think you need to do anything, the recovery.img included in the stock rom you have both been flashing should be the stock one.

In fact as you both have a copy of the stock rom you could skip the twrp backup altogether if you wish. As you can always just fastboot flash the stock rom.
[Thinkpad Tablet General] Chookass:
we agree that the recovery is the one of the YT3P?

Cause ther is no recovery.img in [MENTION=3008044]cotin[/MENTION] archive

---------- Post added at 07:11 PM ---------- Previous post was at 07:10 PM ----------

how do I handle .win? with fastboot fash?

How do I handle the two system archives?
[Thinkpad Tablet General] joesnose:
Sorry, I just thought it would be included in the stock rom!

So only option is for someone to make and share a backup of the original.

I don't have one for the L variant.
[Thinkpad Tablet General] joesnose:
Wait, I think I do!
[Thinkpad Tablet General] joesnose:
I think this is the L variant recovery

https://drive.google.com/file/d/0BzUxZ7PSHbM-M3duN1RqYkNFaVE/view?usp=drivesdk

[MENTION=7459087]Chookass[/MENTION] , you should not have 2 system.img files! What are they called?
[Thinkpad Tablet General] Chookass:
I have in [MENTION=3008044]cotin[/MENTION] archive :

boot.emmc.win

bootloader.info

bootloader.vfat.win

system.ext4.win000

system.ext4.win001

system.info

And md5sums

Are they for flashboot or twrp??
[Thinkpad Tablet General] joesnose:
That looks like twrp.
[Thinkpad Tablet General] Chookass:
Ok restoring using TWRP, it sees the partition «recovery»!
[Thinkpad Tablet General] joesnose:
Well, from the file list you provided, it doesn't appear to include a recovery backup.
[Thinkpad Tablet General] Chookass:
yes my bad ^^

I backed up my own system, which obviously had this recovery partition, and though that I was restoring ^^"
