Oh crap.. So the working link is raw backup..? --- flash-YT3-X90F_USR_S100195_1512052308_WW24_ROW.zip

The other one isn't working.. So far it's the only backup post i found regarding X90F ..
[Thinkpad Tablet General] joesnose:
I can upload a twrp backup, will just take some time. Big upload and slow upload speed.
[Thinkpad Tablet General] tocatalk:
That would be great!

Edit: About the raw images. Which install method is used for it?
[Thinkpad Tablet General] joesnose:
It is already uploading but seriously, last time it took me 3 days for a successful upload!!!

Will let you know when its ready. Lol
[Thinkpad Tablet General] tocatalk:
Wow, 3 days? :eek: Is it because server or your upload speed? Cause if it's the server I think it would be much easier & faster to send it directly, wouldn't it?

[Thinkpad Tablet General] tocatalk:
Hey there Shug, nice of you to drop by :) Is this link for the twrp backup?
[Thinkpad Tablet General] Shug69:
Sorry that's the stock. Having my own issues with twrp. Boot loaderscreen says unlocked and unverified boot (warning 4). Fastboot screen says verified boot. Weird thing is fastboot won't 'tload twrp - verified boot error. Flash twrp gives unrecognisedfile error.. One of those days. ? Flashed stock today to use TiVoapp and now stuck without root and twrp.
[Thinkpad Tablet General] tocatalk:
OK now it gets a little bit Star Wars-like..

*Joe opened the broken Tab, then screwed something inside and Yoga's projector suddenly went on, following a voice message. Voice calling, no.. screaming for help..! it was a man's voice...*

"Help me Joe Nose Kenobi! You're my only hope..!"

The End.

Hehe :laugh:
[Thinkpad Tablet General] joesnose:
Joesnose kenobi, now that's a name I haven't heard in quite some time......
[Thinkpad Tablet General] joesnose:
maybe a fastboot flash of the stock img would fix?

I said MAYBE, dont want things any worse! So at the mo you have a working tablet but no way to load twrp?
[Thinkpad Tablet General] Shug69:
Yeah I have a working tablet and I intent to stay unroofed just now so it could be worse. Problem is I can't flash anything just now- get an error about unrecognised file (like if you spell it incorrectly). Trying to boot twrp tells me command not allowed in verified state. Go figure. Will try to reinstall stock again and fastboot drivers.

Doooh. i was oem locked. was confused by bootloader error screen that said otherwise.

anyway heres a link to a clean twrp latest firmware

https://drive.google.com/file/d/0BzfzROhqO_aeZW9HQ2M0OURQUlk/view?usp=sharing
[Thinkpad Tablet General] tocatalk:
That's what I wanted to point out again, that every restart automatically locks bootloader on dev options.. ^^

Much appreciate 4 uploading the firmware! I'll give it a try in a few hours.
[Thinkpad Tablet General] joesnose:
The allow oem unlock in the dev option just tells the machine you are allowing the unlocking of the bootloader. Once the bootloader is unlocked its unlocked and will stay unlocked till you lock it (don't lock it! Lol) regardless of what the OS says.

[MENTION=4696121]Shug69[/MENTION] lol, glad you got it sorted.
[Thinkpad Tablet General] tocatalk:
Thumbs up for info :svetius:
[Thinkpad Tablet General] daggarz:
thank you very much for your reply, i can't believe i didn't see that.

many thanks!
[Thinkpad Tablet General] tocatalk:
*****PLEASE IGNORE THIS POST*****

It's ment for Joenose

Everything's like you said it will be, just i can't flash it cause it's not shown in restore section..
[Thinkpad Tablet General] joesnose:
You need to put the folder inside twrp/backups folder. That should do it.
[Thinkpad Tablet General] tocatalk:
Omg shame on me.. Sorry, have a load of things on my head lately, it might have affected my sense of logic.. Testing right away. Thanks a million!!

Oh and btw, I do have to disable OEM lock via settings every restart.. if I don't, it won't let me do anything.. Why am I different? :/
[Thinkpad Tablet General] joesnose:
? That is strange, if you don't allow oem unlock what happens?
[Thinkpad Tablet General] tocatalk:
It still won't find it.. maybe you did the backup with another version of TWRP?

When I don't unlock the OEM, terminal says it's locked and won't do anything.

Edit: Would love to take some pics, but unfortunately lost my phone yesterday eve..
[Thinkpad Tablet General] joesnose:
that's the precise location of mine.
[Thinkpad Tablet General] joesnose:
and if you go to fastboot mode on the tablet it says unlocked?
[Thinkpad Tablet General] tocatalk:
Hmm...
[Thinkpad Tablet General] tocatalk:
Exactly.
[Thinkpad Tablet General] joesnose:
Look at the screenshot I posted there's another folder that its inside, starts with YOGA.....
[Thinkpad Tablet General] tocatalk:
And I almost sent you another screenshot showing that I also have this folder.. took me about a minute to realise what's happening.. just...lol

---------- Post added at 12:52 AM ---------- Previous post was at 12:41 AM ----------

K, seems to be working. I'm at encryption stage.

The error 03 is still there thou... I'm really scared to say anything more today, cause my head's like an empty couldron right now..

You have nerves with people like me, my friend.. :fingers-crossed::good:
[Thinkpad Tablet General] joesnose:
Error 3 will stay there unless you lock your bootloader, I highly recomend leaving it unlocked makes things easier when stuff goes wrong.
[Thinkpad Tablet General] tocatalk:
Not for a moment did I think about locking the bootloader. In fact I'm going for root next thing in the morning.. Since I bought this baby in November I only applied two or three minor updates and then you showed up with root possibility.. :) I was so busy with life all the time that I didn't have the time to go through all the procedure again, so I never did.. it's gonna be really interesting to see if updates brought any good.. :)

And while tapping this text I already feel the difference. It's much smoother, won't hang or freeze at all. Hope everything's gonna be that much improved ^^

We'll keep in touch Joenose. As for now I'm going to sleep for the next 36 hours :cool: I really greatly thank you for your efforts and as soon as i will get back on my feet I'll thank you again.

Have a wonderful night!! (or day, depends) :cowboy:
[Thinkpad Tablet General] joesnose:
[MENTION=5271604]tocatalk[/MENTION]. Enjoy [emoji1]
[Thinkpad Tablet General] tocatalk:
Well up until now I feel a huge different. It's so smooth that it feels like I've bought a brand new tab lol.

***UPDATE***

I guess being all excited was too early... Installed some apps and tested some games, and now some things are better, but the others even worse than December updates..

But before I remove these happy words I will root it & disable the encryption.. Maybe it will do the trick.

To be continued..
[Thinkpad Tablet General] joesnose:
Removing the encryption does the trick. Works like it should then.

[MENTION=1128975]ionion[/MENTION]i , is there anyway to change only

etc/hosts

without running under bootloader's error 3 (I guess a predictable no) ?

Don't you think a petition to Lenovo could help to void bootloader errors (and perhaps MM or N update) for this real top-level tablet ?
[Thinkpad Tablet General] oF2pks:
Correct me if I miss something, but after step 7) you get error 3 on each reboot until re-lock ? Also, how do you upgrade (if anymore to come...) with unlocked and error 3 ?

And finally: if you did success any future upgrade (?): can you restore all your app & data ?

IMHO, ionioni and joesnose did prove that every thing will work

if

Lenovo delivers a real unlock-able bootloader ?

Thanks for your complete tutorial !
[Thinkpad Tablet General] grimsgrams:
Yes, if you do this you get error 3 and have to press the volume key furthest from power button every restart to boot. I believe reversing the initial steps (restoring backup, "fastboot oem lock", and then disabling OEM lock in the developer settings) should reverse all of it, but someone else has to confirm that.

The backup is made immediately after OEM Unlock, which is when all data is deleted. So when you restore the backup, you are basically at a factory clean tablet, just unlocked, that can be relocked, and you are back to the beginning. I believe to use Lenovo updates in the future you have to do this, but I really doubt they will make any more updates.

About restoring all your apps and data - well, when you do the above procedure, you do a backup immediately after OEM unlock. But OEM unlock deletes all user data (not system data). So in the process above there isn't any apps and data to backup. Of course, at a later point in time you can run another backup as a restore point.
[Thinkpad Tablet General] SpookDaddy1:
Can someone help me??? I can't seem to figure out how you disable encryption without rooting, as you need root to do a TWRP backup! right? How do you do a backup without rooting? I would really like my tablet to run faster but I'm totally new to all of this and don't really understansd any of it...
[Thinkpad Tablet General] joesnose:
To make the backup you do not need to be rooted but you do have to unlock your bootloader.

follow unlock instructions

Boot twrp

Backup bootloader

Flash bootloader from second post with encryption turned off (THIS WILL WIPE ALL YOUR DATA!)

Enjoy.

Should an update ever come from lenovo! Boot twrp restore your backup, update.
[Thinkpad Tablet General] SpookDaddy1:
Thanks for responding so fast. I have a few questions though... how do I get the bootloader? And how do I get TWRP? When I go to the website it says yoga tab 3 isnt supported... Well I can't find it... Would you mind explaining in a bit more detail as I really have no idea what bootloader is or anything... I managed to get fastboot on this thing though...

Also I seem to have an issue where if I restart the device, things go missing like my folders or widgets and almost always my background goes to the default background :l

thanks so much
[Thinkpad Tablet General] joesnose:
The files can be downloaded from the bottom of the first and second post.

The instructions for decrypting are included in those posts and one page back someone wrote them in greater detail.

Read thoroughly twice, lol

Anything else don't be afraid to ask.
[Thinkpad Tablet General] SpookDaddy1:
I've been at this for like 7 hours hahaha. It just says to make a backup in TWRP and I can't seem to find out how to do that... And to include the boot partition. Idk how to do that

:(

and part 3 makes me totally lost. I have no idea what any of that means.... ugh sorry I'm pretty dumb with this stuff
[Thinkpad Tablet General] joesnose:
Have you installed adb and fastboot on your pc?
[Thinkpad Tablet General] SpookDaddy1:
yes I have! thats the one thing I've been able to do hah. adb recognizes my device and I can reach the fastboot screen on my device

---------- Post added at 12:26 PM ---------- Previous post was at 12:05 PM ----------

hey I just realized someone posted the backup files from their x90L

Mine is x90F though... I can't use it can I?

If I'm actually able to get this working without the crashes and increased speed I'll be so greatful man! hah :victory:

also I just got this so it's still under warranty so I'm extremely afraid of ruining it. I loooove the hardware but the speed and crashing ruin it	:confused:
[Thinkpad Tablet General] joesnose:
Better to make your own backup.

First job, unlock your tablet.

With tablet on go to settings/about tablet, click on build number 7 times.

Back to settings, now developer options is enabled. In developer options tick allow oem unlock.

turn off tablet and boot to fastboot mode (power on while holding volume up.
[Thinkpad Tablet General] SpookDaddy1:
ok what do i do after that
[Thinkpad Tablet General] joesnose:
Connect tablet to pc.

In the folder where you have downloaded twrp.img to your pc, put your cursor in an empty part of the window, hold shift key and right click then choose open command window here.

In the comand window that opens enter fastboot oem unlock.
[Thinkpad Tablet General] SpookDaddy1:
ok and then what
[Thinkpad Tablet General] joesnose:
You managed all that?
[Thinkpad Tablet General] SpookDaddy1:
not quite yet but I thought I'd ask prematurely hahaha

I need to extract that file right?
[Thinkpad Tablet General] joesnose:
Ok lol. Forgot one thing. Copy the unencryption zip you downloaded from the first post to your tablet.
[Thinkpad Tablet General] SpookDaddy1:
I'm confusssed

okay which one do I copy where and which do I extract? theres 3 links so you can just say 1 2 or 3 haha

oh okay wait... sorry.. lol. I think I got it

I put it in the sd card right?
[Thinkpad Tablet General] joesnose:
Second post of this thread, download them both. Extract twrp one and copy the other to your tablet, probably external sd is best.
[Thinkpad Tablet General] SpookDaddy1:
ok so I do NOT extract the disable one? I just copy it to my sd card? then what do I do with the extracted one?
[Thinkpad Tablet General] joesnose:
Leave it on your pc.
[Thinkpad Tablet General] SpookDaddy1:
aw ****. I just noticed my computer is no longer noticing the tablet. like it doesnt show up on my computer when its in fastboot mode!

wat dooo

---------- Post added at 02:13 PM ---------- Previous post was at 02:00 PM ----------

should I do this out of fastboot mode? when the tablet is on?

---------- Post added at 02:26 PM ---------- Previous post was at 02:13 PM ----------

:(

I'm scared to do anything before you telling me what to do haha. I don't wanna wreck this thing :eek:
[Thinkpad Tablet General] joesnose:
No worries. You havnt done anything dangerous yet! Lol

The tablet will only show up as a fastboot device while in fastboot mode( power on while holding volume up, bunch of options on screen.
[Thinkpad Tablet General] SpookDaddy1:
yep its in fastboot mode but its not showing up on my computer.

unless... is there a special way to see it when its in fastboot mode? its acting like its not even connected to my computer
[Thinkpad Tablet General] joesnose:
But previously it was?
[Thinkpad Tablet General] SpookDaddy1:
yeah when its not in fastboot mode it shows up on my computer
[Thinkpad Tablet General] joesnose:
On your pc with tablet connected to usb in fastboot mode type in command prompt

Fastboot devices
[Thinkpad Tablet General] SpookDaddy1:
"fastboot is not recocgnized as an internal or external command"

ugh seriouslyyy. Took me forever to do that **** and I got it wrong -_-

I HAVE the damn file. It says fastboot on my computer

I can go into fastboot on my device.

wtf?
[Thinkpad Tablet General] SpookDaddy1:
UGH....stayed up all damn night working on this xS It doesnt want to let me install the fastboot driver on it :/
[Thinkpad Tablet General] SpookDaddy1:
what would happen if I uninstalled the driver... could I then install fastboot driver?

Ugh I really want to make this tablet useable :(
[Thinkpad Tablet General] joesnose:
http://xdaforums.com/showthread.php?t=2317790

You need to install that.
[Thinkpad Tablet General] SpookDaddy1:
I have that

Sorry for all the questions haha... Idk why it isn't working for me...

here.. This pic kinda shows all of my problems!

and I've tried unchecking the "show compatible hardware"

doesn't show any option for it either :rolleyes:
[Thinkpad Tablet General] joesnose:
Private message sent.
[Thinkpad Tablet General] SpookDaddy1:
Huh... After all of that my tablet says its still encrypted!!!!

Heeellpppp :(

I put the disable file on my SD card rather than device... Maybe that's why?

Hah I'm afraid to do anything because I don't wanna mess it up!
[Thinkpad Tablet General] grimsgrams:
Did you install the unencrypt-zip file using TWRP?

Did you type Fastboot Format Data and see a bunch of stuff pop up?

If both of those are true then it shouldn't matter what it says. The data might just say it's encrypted because it believes it should be encrypted, even if it's not.
[Thinkpad Tablet General] pananza:
I know it says in the first post "Please do no relock you bootloder". I have to ask since the warning on each boot is quite annoying. Any way to remove it?
[Thinkpad Tablet General] joesnose:
The only way to remove the error message it is to lock your bootloader.
[Thinkpad Tablet General] felcolar:
guys, please help me I follow the steps, but my tablet doesnt work anymore it say bootloader error code 3, I fixed by locking it agian, and now shows a error code 01 and 02 I didnt make any backup cuz didnt show ay option for that, what should I do now?

system doesnt boot just show the errors.
[Thinkpad Tablet General] joesnose:
locking has not fixed anything.

You need shug69 s backup. Can be found in this thread.
[Thinkpad Tablet General] pananza:
Yes, but will it boot when still rooted and unencrypted? Or do I need to restore the backups in order to boot with a locked bootloader?
[Thinkpad Tablet General] joesnose:
Good question.

You can be rooted and oem locked......

The unencryption relies on a modified bootloader, so even IF it booted when oem locked you would still get an error as the bootloader has been modified.
[Thinkpad Tablet General] joesnose:
Sixaxis app is now working after a recent update :)

Unfortunately the hacked remote play app for ps4 no longer works :(
[Thinkpad Tablet General] pananza:
I've been wondering. Since we with this TWRP have bios access. Is it possible some way to enter bios, enable USB OTG boot and boot Windows 10 from a USB stick? It's an 64-bit Intel Atom processor so it should (in theory) be able to run Windows 10.
[Thinkpad Tablet General] joesnose:
Well this was the original thinking, but the bios is very crippled and would need editing by someone who knows their stuff!

Becareful if you poke around bios, many ways to brick!!!!!!!!!!
[Thinkpad Tablet General] grimsgrams:
Shutdown at 30% battery

edit: looks like this was battery related and not root related
[Thinkpad Tablet General] emilgeorge1234:
Very strange and kinda worrying. I haven't rooted yet. Currently enjoying UN encrypted tablet with all its freedom. Since LENOVO had made this as near to stock Android, I can't really see why I should root it anyway. For Intel 64 chips no much tweaking software available such as Xposed. . However, I have rooted 3 of my Android phones already which had their perks. Hoping that one day someone will make a custom Rom for tab pro!!!!

---------- Post added at 09:20 AM ---------- Previous post was at 09:18 AM ----------

If someone could tell me why I should root this tablet, it would be great. Thanks for keeping this forum alive
[Thinkpad Tablet General] joesnose:
Not sure that this is a problem caused by rooting. you can always restore your backup to confirm that the problem does not persist.

The fact that its happening inside twrp environment suggests hardware issue! Twrp is another OS if you like and should not be affected by android root access.

Just haven't come across this issue before.
[Thinkpad Tablet General] joesnose:
Indeed, no xposed is a good reason not to root.

I am not sure how well xposed would work with the VibeUI ! I have a huawei phone that xposed works with but in very limited capacity as huawei uses EMUI.
[Thinkpad Tablet General] cotin:
Anyone that can confirm that Xposed works with X90L?
[Thinkpad Tablet General] joesnose:
as far as I know there is no xposed for x64 bit architecture.
[Thinkpad Tablet General] cotin:
Awww thats super lame. Oh well, one day in the future maybe!

I'm trying to get into fastboot mode, so that the "fastboot boot twrp-2.8.7.0(6)-x90.img" command works.

Can you yell me what should be on the tablet screen when I run this command, please?

at the moment it always says "waiting for device"
[Thinkpad Tablet General] joesnose:
Tablet should load TWRP recovery.

From there restore your backup.
[Thinkpad Tablet General] RedMist:
The tablet does not load TWRP by default. I think I have to type "fastboot boot twrp-2.8.7.0(6)-x90.img" to run it.

But when I do it always says "Waiting for device"

I'm not sure what mode the tablet should be in. e.g. If it needs to be in "fastboot mode" what should be on the screen??

Sorry... As you can tell I'm a bit confused :)
[Thinkpad Tablet General] joesnose:
Sorry missed the waiting for device part.

You have your tablet connected by usb and in fastboot?
[Thinkpad Tablet General] joesnose:
boot tablet.

Error code 3 ?

Press volume down.

You should now be on fastboot screen.
[Thinkpad Tablet General] RedMist:
Like this picture?
[Thinkpad Tablet General] joesnose:
Yes that's it.

You have the usb connected?

Also in the fastboot boot "twrp.img" you want to remove the quotation marks.
[Thinkpad Tablet General] RedMist:
Yes cable attached (plays a little tune when attached and detached)

And quotes removed.

Could the fastboot drivers be wrong? When I fully boot the tablet, "adb devices" shows the tablet correctly
[Thinkpad Tablet General] joesnose:
What does the tablet show up as in device manager while connected in fastboot mode?

Well seeing as how you have run twrp during the root process it should be working and is playing you a nice little tune upon attaching/detaching.
