hi there again.

[MENTION=2195656]joesnose[/MENTION]

after the latest ota-update to security patch level januar 2017, the battery looses far more capacity to "android-system" than before, especially in standby. so i decided that root now is needed to remove some unwanted apps and see what it does to this problem. after doing so, unfortunately all around root is functioning fantastic except the "loosing-power-in-standby"-problem. because i want to go back to the good old firmware (6.0.1 with security patch level august 2016) i buyed a new one from amazon just for grabbing it from this device and put it in my old one. now the questions:

- is it only unlocking the bootloader, fastload twrp, backup the partitions and lock the bootloader again that should do the trick?

- which partitions are needed to bring the system back to the august 2016 level?

- can it cause problems to flash partitions from other similar devices?

- is there more to watch over?

i got some fears to brick the new tab, because it was expensive and the reason is, that amazon should have to take it back ...

thank you for your answers mate, not only for this questions :highfive:

edit: backing up all partitions without unencryption seems not possible. but if i unencrypt, is there afterwards a way back to encryptet data-partition? or is it no problem locking the bootloader again without re-encrypt the data-partition? or, best of all, do i only need the system-partition?
[Thinkpad Tablet General] joesnose:
Sorry just saw your post.

To get pure backup you dont want to unencrypt. You can ignore the data partition, this is just where your apps and personal stuff is stored.

ROOTING

I finally got to unlock bootloader thanks to PDA Net trick, but now, after installing SuperSU it seems that im stuck on booting. This fancy Lenovo appears with various pictures and then i'm stuck on orange logo (turning red and back to orange). Recovering my backup doesn't seem to help. Any advice? Maybe somebody can send me his backup? Or should i just turn it on and put it beside my bed for one night?

Got X90-L.
[Thinkpad Tablet General] joesnose:
What version is it 2Gb or 4Gb and what version of supersu did you use?
[Thinkpad Tablet General] radekg12:
I got 2gig version. Everything is alright now. It took my tablet like 0.5h to boot after installing this superSU. Decrypted it just now and it works. Still stutters because of kernel problems though.
[Thinkpad Tablet General] RedMist:
On original hardware..

I've done a TWRP restore, but still getting error code 3

Shall I do a "fastboot oem lock"?
[Thinkpad Tablet General] joesnose:
Unless you are selling the device i would leave unlocked and keep bootloader error. But its up to you.
[Thinkpad Tablet General] mach3taz0:
hello,

id like to ask you if you could help me please.

i wanted to restore my tablet to previous original setup. performed restore of previous backup and still got error code 1. so thru adb i did fastboot oem lock. now i stucked and tablet is not working at all.

when i start tablet i have error code 1 and can power off tablet of recover...

now, also fastboot oem unlock is not working.

is there any way how to reverse this situation please?

(after system restore, i probably forgot enable oem unlock?)
[Thinkpad Tablet General] joesnose:
What version of the tab are you using?
[Thinkpad Tablet General] mach3taz0:
hello

it is model yt3-x90f
[Thinkpad Tablet General] joesnose:
2 gb or 4 gb?
[Thinkpad Tablet General] mach3taz0:
sorry forgot mention it. it is 2gb version
[Thinkpad Tablet General] joesnose:
Shug69 posted a link to the stock rom in post 145, dont know if its still active but worth a try.
[Thinkpad Tablet General] mach3taz0:
went thru this forum already but links are dead.

so only one solution is to install stock rom (if i find some) thru rocovery mode / apply update from sdcard?
[Thinkpad Tablet General] joesnose:
you cant run twrp anymore as the bootloader is locked. The files posted by shug69 needed running from dnx mode as i remember. Was just scouting around to see if i could find it, will carry on looking.

The stock roms posted by others seemed a little different, not sure how they need to be flashed.
[Thinkpad Tablet General] mach3taz0:
oh. not good for me :)

thanks a lot for your help so far
[Thinkpad Tablet General] joesnose:
found it.

Just uploading it but my upload is pretty slow, i will send you a link tomorrow.
[Thinkpad Tablet General] mach3taz0:
wow that's great! much appreciate your help

see you tomorrow
[Thinkpad Tablet General] joesnose:
https://dfiles.eu/files/qt9epja74

Readme and drivers included.
[Thinkpad Tablet General] mach3taz0:
thanks a lot. just downloaded it. but during flash process got "error on flash system" .

prior to flash i also reinstalled drivers from your package. went to dnx fastboot mode and run run_me.bat.

in cmd i saw

"formating system..."

"flashing system... "

and then

"error on flash system"

have you seen such situation pls?
[Thinkpad Tablet General] joesnose:
Yes i have seen this before. Try this link instead.

https://yadi.sk/d/6vUxX9Iyv2Lzz
[Thinkpad Tablet General] mach3taz0:
yes! this one works fine! now i have tablet back.

much appreciate your help and time

owe you beers
[Thinkpad Tablet General] joesnose:
Great!
[Thinkpad Tablet General] dskmusic:
this for 2 or 4gb version?
[Thinkpad Tablet General] joesnose:
2gb
[Thinkpad Tablet General] stapler85:
this tablet, oh man, the few owners out there like us, i dont know how to explain it, but i really want to like this tablet however due to the lack of support and the high price its frustrating, im so tempted to move to a galaxy tablet but on other hand im in love with the hardware like hinge stand and the neat projector, i cant let go of this tablet easily as theres no tablet out there like it! this could be the best tablet if only Lenovo provides better firmware and if there are aftermarket rom supports, the hardware is fantastic. Real shame, if only Lenovo went for a snapdragon cpu we may have a shot at roms.
[Thinkpad Tablet General] el3c:
Android 6 is nearly there... And it seems, beta users told that, the New Firmware will solve all issue :)

https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/lt01_en/thread-id/12115/page/68

Tomorrow i will restore my twrp Backup and hope for the upcoming ota on 27.05.2017
[Thinkpad Tablet General] mletchworth:
Yeah, the beta is running very smooth. It doesnt fix all the memory issues, but after using this tablet for 18 months, it's so much better now. Too bad they probably lost quite a few customers between now and last December, when they said the update would be released.
[Thinkpad Tablet General] el3c:
Android 6 Update is now live!

---------- Post added at 07:12 PM ---------- Previous post was at 06:18 PM ----------

@joesnose i ve done the steps to root my yoga, so i have a full backup. what is the right way to restore my backup?

should i format anything before and if yes, what shoul be wiped?
[Thinkpad Tablet General] joesnose:
Just restore your backup, it will overwrite the partitions.
[Thinkpad Tablet General] el3c:
thanks! and after that, i locked the bootloader :)

now ota for Android 6 is downloading, very slowly, but downloading .... is it possible to gain root on android 6 with the same method?
[Thinkpad Tablet General] joesnose:
Well on the 4gb version its mostly the same except use magisk not supersu.
[Thinkpad Tablet General] el3c:
lol.. i ve tried, enabled debugging and oem unlocking wthin dev options, tried that:

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock

...

FAILED (remote: unknown command)

finished. total time: 0.017s

any ideas why that happens?

EDIT: it was, you rdy wrote that: fastboot flashing unlock
[Thinkpad Tablet General] joesnose:
Sorry i need to update the first post!

All worked out?
[Thinkpad Tablet General] el3c:
yep, fastboot flashing unlock done this on the new Android 6 Rom (2GB)

Done a full backup yet and try now to use magisk.

Edit: does encryption : x90-disable_encr.zip also work on Android 6?
[Thinkpad Tablet General] dskmusic:
Try this command:

fastboot flashing unlock
[Thinkpad Tablet General] Lusanagi:
Do we need to re-lock the tablet to be able to update? I thought it didn't matter (if I remember correctly, previous updates were unlocked and didn't have a problem)

Also, has anyone been able to update? the download is sooo damn sloooow!

If yes how's the rooting and decryp? Still need magisk root, or can we use SuperSU?
[Thinkpad Tablet General] joesnose:
Dont have to relock to update. Maybe just unroot as magisk is systemless. (Messed mine up before update so had to full restore)

I can confirm supersu still causes hang on boot. Tried with latest, 2.81.
[Thinkpad Tablet General] Lusanagi:
That sucks. Guess I'll have to download magisk then (never used it before).

What about decrypt?
[Thinkpad Tablet General] joesnose:
Unencrypt still works, but thiz might be what caused me to do a full restore.

if you are unencrypted you could try.

Make backup of data using data enabled twrp.

Full backup restore, this will force encryption of data as original boot.img will be applied.

Take OTA.

Make new full backup!

Run unencrypted script.

Install magisk.

Restore data backup (dont know if ota update will mess with this but should be minimal if any)
[Thinkpad Tablet General] Lusanagi:
thanks [MENTION=2195656]joesnose[/MENTION], I'll give it a try as soon as the OTA finishes downloading (hope by tomorrow)
[Thinkpad Tablet General] joesnose:
! Tomorrow

Is this the update from lollipop to marshmallow?
[Thinkpad Tablet General] Lusanagi:
yeah, it is, but for some reason it is way too slow to download (I've already reset it twice because it gets stuck on 2%, and one of those was after I arrived from work and supposedly left it downloading all day ¬¬)
[Thinkpad Tablet General] joesnose:
Ouch! Lol

There may be a few more issues restoring data from lollipop to marshmallow. Might be better using titanium backup.
[Thinkpad Tablet General] Lusanagi:
Actually the tab is encrypted and unrooted right now, and since I don't have much installed, no big loss if I lose info
[Thinkpad Tablet General] Necrobis:
Hello, i had to restore one of my two TWRP Backups. SIM Card is not working on the one Backup. The other one seems to be broken. Installation stops with error code 211. Maybe anyone has a full backup for the new 4gb ram 64gb rom version with LTE?
[Thinkpad Tablet General] Necrobis:
Ok i found out that my own 2 Backups were broken. Only UUUUUUUUUUUUUU instead of the Normal Data. The third Backup I have, is restorable. Android starts but my SIM-Card is not working. I dont know why.

Maybe anyone has a complete Backup for YT3-X90L 4GB? Thank you all.

[Thinkpad Tablet General] airheadbg:
Hi Guys,

I have a question, I followed the instructions, unlocked the tab and started TWRP, however no I have a problem. I put an SD card with the supersu.zip and on which I wanted to make the backup, however when I try to make a backup or browse the SD card I get an error "Unable to mount storage".

I thought maybe it's not mounted, but when I go to mount I cannot select Micro SDCard. Anyone else had the same problem or has any idea on a solution?

Thanks in advance
[Thinkpad Tablet General] joesnose:
did you get this sorted?
[Thinkpad Tablet General] joesnose:
What format is your sd card?
[Thinkpad Tablet General] airheadbg:
FAT32
[Thinkpad Tablet General] joesnose:
Never came across this problem. Maybe try another sdcard if you have one, or a usb stick with an otg cable.
[Thinkpad Tablet General] fp1707:
I am extremely sorry I have been an utter idiot. But I didn't make a twrp backup for my yt3-x90f.

Is there anyone kind enough here who is willing to share me his/her backup? Please? Thanks a lot if someone actually does share their file.

Or if anyone know a place where someone shared this file already, mind linking me to that place?

I would highly appreciate any and help that may come my way. thanks

When I do fastboot flashing unlock, its just lists out the possible fastboot commands for me instead of unlocking or running a command. I am using systemwide adb and fastboot btw.
[Thinkpad Tablet General] radekg12:
Tommorow is supposed to be the day guys. So i wanted to switch back to encrypted version and as shamefull as i can be, it seems i deleted it. Anyone is able to support with X90L encrypted backup?

Hello,

I did the Ota update and rooted the tablet using the instructions from first post and Magik. Is the unencryption thing still applicable within Marshmallow?

Thanks

Ronny
[Thinkpad Tablet General] fp1707:
Yes. I decrypted mine it worked. However the difference it creates is minimal compared to how it was back in lollipop.

To get some performance boost, what I did was downscaled the display to 1200p instead of 1600p. And this actually really works. Even better when you put it lower to 800p but that starts to look very bad. 1200p is still fine for me, barely noticeable.
[Thinkpad Tablet General] dskmusic:
Ho do you reduce the display resolution?

in the other hand, my tab 3 pro always run at maximum clock speed. The tab enter fine in deep sleep mode, but when I use anything, always run at max.

I use cpu governor to reduce to 1440mhz... but someone know something about this issue?

thanks!
[Thinkpad Tablet General] fp1707:
https://play.google.com/store/apps/details?id=com.chornerman.easydpichanger&hl=en

Also it's downscaling not actually reducing.
[Thinkpad Tablet General] dskmusic:
thanks! what numbers are you using? only change dpi?
[Thinkpad Tablet General] fp1707:
I did some math and some trial and error to find these numbers. You are free to use them. Offcourse the largest numbers are for QHD. The numbers in mid are for FHD and the smallest numbers are for 720p(well actually 800p). Note: not all changes show without a reboot.
[Thinkpad Tablet General] fp1707:
What is it day for tomorrow? Is it when the x90L version gets MM?:)
[Thinkpad Tablet General] radekg12:
Yesterday, yes. X90L got MM. It actually is possible to update your Yoga Tab 3 decrypted without any problem. After update it just leaves bootloader error 3, but it's just a minor thing considering how bad it was using this tablet.
[Thinkpad Tablet General] dskmusic:
Thanks!!
[Thinkpad Tablet General] paultsr:
which is the latest OTA update version??
[Thinkpad Tablet General] vladutgm:
Last firmware?

Mine is this: YT3-X90L_USR_S200307_1706140050_WW17_BP_ROW with MM.
[Thinkpad Tablet General] cotin:
We need a updated ROOT instruction for the new Yoga tab 3 Pro update to Android 6.0.1 [MENTION=2195656]joesnose[/MENTION]
[Thinkpad Tablet General] vladutgm:
I have YT3-X90L with 2GB RAM and I used the tutorial on first page (with magisk) for root and it works.
[Thinkpad Tablet General] cotin:
And you have the latest update installed too?
[Thinkpad Tablet General] vladutgm:
Latest update was to Android 6.01 from lollipop. Another update is not visible from update menu.
[Thinkpad Tablet General] cotin:
Yeah I didn't see the updates in the tutorial.
[Thinkpad Tablet General] vladutgm:
Update is OTA (over the air). Old firmware (no root) was Lollipop; over the air arrived android Marshmallow. After update, I followed the tutorial from first page using Magisk (not superSU) and now yt3 x90l with 2GB RAM own MM with root.
[Thinkpad Tablet General] palsedo:
Hey. Anybody here who can give me a stock backup from x90f? 4gb ram/64gb/Android 6 version?
[Thinkpad Tablet General] luca.costantino:
how to do it?
[Thinkpad Tablet General] palsedo:
Backup with twrp and upload to mediafire?
[Thinkpad Tablet General] luca.costantino:
I'm not rooted and I have the stock recovery.
[Thinkpad Tablet General] palsedo:
You dont need to root your device. just install twrp and backup your system
[Thinkpad Tablet General] luca.costantino:
I have the stock recovery and I don't want to change it , yet.
[Thinkpad Tablet General] joesnose:
You dont need to change anything you can run twrp as a live session. No changes are made to your tablet.
[Thinkpad Tablet General] stapler85:
folks, how do you install OTA updates when you have bootloader unlocked and rooted? do you must restore TWRP to stock THEN do OTA then root again? there must be a easier quicker way to take Lenovos OTAs

Been messing with this for days and I can get the Yoga YT3-x90f to show up in the ADB DEVICES but when i put it in FASTBOOT and do FASTBOOT DEVICES it does not show. Any ideas?
[Thinkpad Tablet General] joesnose:
Update to latest fastboot drivers on pc.

Pretty sure I have done that but is there a command for showing version, what is the latest/where do it get it cause thought I had it
[Thinkpad Tablet General] joesnose:
To be honest i am a little out of touch. this is almost certainly a fastboot driver issue. From what i remember i downloaded the latest android sdk but chose the just driver installation . There may be an easier way but like i said sounds like a simple driver issue.

have you tried pdanet? install on your pc, then install pdanet app on your lenovo droid.

Okay so I got the Fastboot to work by finding an Intel driver that helped. Now I have down everything and since I have marshmallow i used the Magisk to root. It appears to have run successfully within TWRP but when it boots up and I run a root checker in Android it deos not find the root. Any ideas on this
[Thinkpad Tablet General] joesnose:
Have you tried to run any apps that need root?
[Thinkpad Tablet General] joesnose:

[Thinkpad Tablet General] jwiggins0123456789:
I ran ES File Explorer and choose the ROOT EXPLORER option and it enabled it but when I install Lucky Patcher it seems to have no root access and when I try to install a modded apk it fails. Also when I run the Es File Explorer and try to go to any root location on the tablet the folders are all empty. I am thinking I am not getting rooted somehow but the TWRP install of the Magisk.zip completes successfully
[Thinkpad Tablet General] daWyrd1:
have you played around with magisk manager? does it say magisksu is enabled?
[Thinkpad Tablet General] jwiggins0123456789:
Do not have a magisk manager that I can find installed... will look for that and see what I can do with it
[Thinkpad Tablet General] joesnose:
I am guessing you have tried uninstalling and reinstalling magisk? There is a workaround for lucky patcher, cant remember what now. You have to change something in lucky patcher settings.
[Thinkpad Tablet General] jwiggins0123456789:
THANK YOU THANK YOU THANK YOU guys!!! Got the Magisk Manager installed and everything started asking for root access and I could install my modded app. THANK YOU
