Simple question on Yoga Tab 3 - 8" WiFi only version

I am looking at either the 8" or 10" version to finally upgrade from my original Moto Xoom and I am finding conflicting information online.

Can someone confirm if the 8" version has GPS support?

-Lenovo site does not mention it.

-Some review sites say yes, some do not mention it or they combine it with LTE versions so it is unclear.

-Lenovo online chat said no, but it sure seems the 10" and 8" share 99% the same hardware and the 10" does support GPS.

For my use I need this support for offline navigation but I really do not want the larger 10" tablet. My current tablet is 10" and it is just too big for how I want to use it.

That process is for the pro version of the tablet with the projector. Does that also work with the YT3-X50 models? I haven't done much with this tablet yet for fear of bricking it.

yeah same here, but it gets better after awhile. but access system stuff does slow it again.
[Thinkpad Tablet General] Neo0:
As I mentioned in post #84, installing the latest version of busybox solved the crashes, etc :)

Maybe it'll work for you

Gesendet von meinem D6503 mit Tapatalk
[Thinkpad Tablet General] Hastaloego:
im using busybox and there arent crashes, it is just slow sometimes up to freezes for some seconds.

when i open a system app or something like that, it takes now several seconds to open and sometimes the pad doesn't respond anymore at all for some seconds.

with xposed the my x50f feels way more laggy in general than without.
[Thinkpad Tablet General] Neo0:
That's strange, I'm not facing those problems. Busybox and xposed are working without problems and my tab isn't slower.

Did you wiped your caches?

Gesendet von meinem D6503 mit Tapatalk
[Thinkpad Tablet General] Hastaloego:
i have those russian twrp running, and after install of xposed i did wipe cache.

the first start then took like for ever and i think i get a system fc too.

then it runs, use able in general, but its slow and laggy

which xposed are you using ? i tried the latest: xposed-v80-sdk22-arm.zip
[Thinkpad Tablet General] Neo0:
I did it the same way. Yes, I'm also using the latest version. Did you update Busybox before or after flashing xposed? For me the only way to avoid the lags was to first install busybox and then xposed.

I remember that I also set SELinux to permissive, maybe that does the trick?

Gesendet von meinem D6503 mit Tapatalk
[Thinkpad Tablet General] Hastaloego:
im running busybox v1.24.1, did change SELinux to permissive with http://xdaforums.com/showthread.php?t=2524485 (or did you do it manually ?)

now i will install xposed again, lets see whats going to happen..

same :( very slow responding at start, like its down to 100mb ram running at 100mhz cpu

starting kernel adiutor took 30 sec

edit: did Antutu Test with and without.

no xposed: 22816

with xposed: 22611

but those 200 points cant be the reason for the laggy behaviour.. has to be something else..

i have the wifi only version with 32gb rom / 2gb ram yt3-x50f / 1,3ghz quadcore 32bit qualcomm

running 5.1.1

build number: YT3-X50F_S000020_160216_ROW

kernel: 3.10.49

edit 2: looks like the wipe cache doesnt trigger the xposed app optimizing somehow.. it seems that only the first start is laggy. once the app is loaded i can force kill it and the next start seems to be at normal speed.. really weird

Yes it works fine, the auto rotate bug is gone, so far and it runs very smoothly. I was running the previous version 82 and the first run was very slow but and was a bit erratic. But 83 is working fine.

You just need to flash the zip in recovery mode and wipe the caches and reboot.

Found stock ROM but now OTA not available

I found a stock ROM for the YT3-850M from: androidmtk dot com/download-lenovo-stock-rom-models. I flashed it using stock recovery (per included instructions) and at least I can now do a factory reset and show a clean unrooted device. The problem is it's an older build than the one it shipped with, and it's showing no OTA updates are available. (System update > "This is the latest version".)

Current Build number: YT3-850M_S000024_150714_PRC

the newest version of kingroot work very well... google is your friend.

Why try to install super su on a yoga 3 tablet when Kingroot does the job. It's only a Yoga 3 , you won't be able to install MM6 or whatever miracle apps on this tablet. As long as you have root , it's good enough IMO. Unless you want to get a backup of a rom that you can find easily on the lenovo website. here is the link for kingroot V4.93 release_2016_06_06

list of all Lenovo Yoga Tab 3 models

Right, here's the full Lenovo Yoga Tab model run-down according to my own research:

released 2013: Lenovo Yoga Tab series (B600 / B8000)

released 2014: Lenovo Yoga Tab 2 series

released 2015: Lenovo Yoga Tab 3 series; 3 models x 3 versions of each model = 9 distinct devices (see below). I think region is the primary factor that determines which models are sold in which parts of the world.

Wi-Fi only (no SIM card slot)

:

Lenovo Yoga Tab 3 8" (YT3-850F)

Lenovo Yoga Tab 3 10" (YT3-X50F)

Lenovo Yoga Tab 3 Pro 10" (YT3-X90F)

Wi-Fi + data

:

Lenovo Tab 3 8" (YT3-850L)

Lenovo Tab 3 10" (YT3-X50L)

Lenovo Tab 3 Pro 10" (YT3-X90L)

Wi-Fi + data + voice

:

Lenovo Yoga Tab 3 8" (YT3-850M)

Lenovo Yoga Tab 3 10" (YT3-X50M)

Lenovo Yoga Tab 3 Pro 10" (YT3-X90X)

Or if you fancy categorizing according to screen size:

8-inch

:

YT3-850F

YT3-850L

YT3-850M

10-inch

:

YT3-X50F

YT3-X50L

YT3-X50M

Pro 10-inch

:

YT3-X90L

? the download at dropbox is 1.2 gigs , other are at 783 Megs, x-drivers.com at 1 . 0 gig., androidmtk dot com was blocked by my AV and I think that MTK would relate to mediatek which cpu is used in some versions of the yoga.

but anyway, there is a BIG difference between the size of the L/M firmware that you propose and the one of the lenovo website !!! I wonder why, does the lenovo small firmware make it so that it will download the remaining files depending of your country and other settings ? WEIRD ! Plus the guy who asked for a firmware never told us if he has a L/M model or a F model, anyway he now has enough link to keep busy for a while :) he should make sure to download the right version for his tablet though.

Lenovo has a very good live Chat support , so if he's lost he can go ask them.

I should have said that mine is the YT3-X50F. Messed up by using Kingroot, then trying to replace with Supersu. Been looking everywhere, a stock ROM. Only place I have found is here:-

[Thinkpad Tablet General] Belk21:
For those that had the Block.map issue when trying to update via OTA. I experienced this too. I looked at the recovery log and noticed the error was associated with the Boot image. I then reflashed everything and I also flashed the Boot.img from the SW folder and I was able to update successfully. Hopefully this worked for y'all too. I am using a YT3-X50F.
[Thinkpad Tablet General] zigonneux:
this is why i only use kingroot, to make sure I don't mess it up too much. But then , beside the security patches, what else does lenovo will be sending as an update, certainly not MM6. I'm not sure if we can just remove kingroot and everything goes back to normal !!?! The yoga is my bedside tablet for podcast and usb mini DAC connection for earbuds , so , as long as my podcast and usb music app are updating, i don't care much about the lenovo updates. I have this tablet for many months now and never saw an update from lenovo. Kingroot is installed only since 1 week.

I wonder why you guys don't trust the files on the lenovo website, they are the real thing... only 130 megs for the 50F but unzip to 800 megs.

Return back to stock

Hi guys. I own a yt3-850L and since I'm going to sell it, I was going to take it back how it was in the past (flashing a stock rom).

My version is YT3-850L_S000024_151016_ROW. Where can I download this stock rom?

I downloaded the open source code from Lenovo: lenovo_yoga_tab_3_8_osc_201511.tar.gz,

It's the same thing? How can I use it?

Thanks
[Thinkpad Tablet General] zigonneux:
Why not just do a factory reset instead of installing the rom again, was it rooted ?

there is a recovery with the lenovo rom to flash a factory image. There is a post on the yoga 3 section about this...

read this , it's for the F model but it's more or less the same operation : http://xdaforums.com/thinkpad-tablet/general/unbrick-yoga-tab-3-how-to-unbrick-t3349037 Yoga Tab 3 - How to unbrick, and restore to stock.

Yes that small file ( 232 megs) is the firmware, it might look small but once unpacked it grows up to more than 1 gig. ( do not unpack it, flash it as it is) You might have to flash a small Gapp after the rom but boot to the rom first once installed. and check if it's successful.

I am NOT responsible if you brick your tablet. These up here are just suggestions, not the bible. If you can just do a normal factory reset, do it.
[Thinkpad Tablet General] Toriko:
Yes. It's rooted and with TWRP. Unfortunately I cannot do a factory reset because there aren't any of the previous apps. I cannot find any information regarding this recovery: where can I found It and How do I use It.

Alternatively, are you suggesting that I can follow the instructions of that post and flash the file lenovo_yoga_tab_3_8_osc_201511.tar.gz ? Will the original recovery be restored? Thank you
[Thinkpad Tablet General] zigonneux:
The original recovery will not be restored unless you remove TWRP after installing the firmware . AND I've seen the normal recovery from lenovo and you could install the firmware with it, so you could remove TWRP and unroot it before installing that file. I have my lenovo tab3 right here let me check the recovery options, be right back.

---------- Post added at 03:12 PM ---------- Previous post was at 03:06 PM ----------

go to the lenovo recovery, by pressing start and volume up has the options :

Apply update from ADB

wipe data /factory reset

wipe cache partition

reboot to bootloader

power down

view recover log

APPLY UPDATE FROM SD CARD. <--------

It is like the Samsung TabS 10.5, we can have TWRP installed but we still have access to the "Download" recovery page anyway. to use with odin.
[Thinkpad Tablet General] Toriko:
Sorry to bother you, but It's my first time with a Qualcomm.

1) Why can't I flash the .tar.gz file directly from the TWRP?

2) How can I remove TWRP and unroot before flashing?
[Thinkpad Tablet General] zigonneux:
TWRP can only be removed by flashing another recovery.img . You can use flashify to do that.

TWRP can't flash a .tar.gz file . This is why they use the SD card and the lenovo recovery to flash the firmware. Can you access it ?

Unrooting is done with the supersu app, by telling it to fully unroot your device.

I have seen somewhere : Factory image has to be flashed via fastboot, not via recovery. So either you use the lenovo recovery if you still have it or flash with ADB fastboot

I'm trying to get you the recovery.img from that tar firmware
