On lenovo-forums.ru U can read about trials to upgarde 850L with 850M firmware - there to be over with failure in one point - imei error and the device cant login to network /but everything besides that works fine/. Guys from forum don't make qcn file backup /or don't know first owner password to google/ - this is not only information about imei. In this file U can find antother things like bands etc I don't know how US networks works but U have device from middle east where information like bands or imei are important. So make qcn file backup with qfil. U find solution how to get this file for example in post http://4pda.ru/forum/index.php?showtopic=687964&st=520#entry48057629 - points from 1 to 9 after that U can use qfil to backup.

YT3-850M's TWRP works on the YT3-850F

[MENTION=7000441]zigonneux[/MENTION], thanks for the file. I tried it on the YT3-850F and it works like a charm. I've already flashed zips and images without a problem.

Hello Masters!

I have a problem - my customer give me YT3-X50M to repair - He has done wipe data/factory reset from recovery menu (power+volume up). FRP was not disabled evidently - the message "Device was reset ..." is displayed. Problem is, he don't know e-mail or password (or phone :)) he provided before. Because he only need access to google play, so he created new account aka blablablah@gmail.com with some creepy password (his words). The trick with calling setting via @ doesn't work - there is no more any menu after long push @.

ROM version is YT3-X50M_USR_S000127_1611241727_Q1241_ROW

Is there any possibility to solve this?
[Thinkpad Tablet General] DeLoreanQC:
The 6.0 OTA is available in Canada !
[Thinkpad Tablet General] SM-T325 LTE:
Please let us know if you manage to capture your OTA update url, if you are trying to do so before installation. I tried with "adb logcat" without success. So, I'm holding off on installing the OTA hoping I can get the actual file. Thanks.

I was getting this, as well, but I went back and flashed boot.img as well from YT3-X50F_S017_151023_ROW_QFIL.rar, as suggested from a fellow several posts back. Worked like a charm, though there was about 10 updates to go through varying from 30mb to 350ish, cumulating to the 900mb (6.0) update.

[Thinkpad Tablet General] luisangelchav:
Hi. You have a F versión. Have touch screen problems?
[Thinkpad Tablet General] yoanbonev:
No, i have it for half a year now, maybe even a bit more. The only issues I had were all related to the lag. Once I've sorted the lag out my yt3 really feels great. (Btw touch is hype sensitive if thats what u mean. My one reacts to the lightest touch, and the anypen technology is great I love it.

I am truly happy that I managed to get rid of the lag and stay stock!
[Thinkpad Tablet General] 350Rocket:
Finally mine is downloading Android 6.0 like a year and a half or whatever after release lol. Just a warning it says it will wipe all data on the update to ensure the best user experience.

Not a big deal for me, but some people will need to back up stuff.
[Thinkpad Tablet General] Princeaha:
Can you tell me where you found this from? I can't seem to find it.

Also, if anyone else has found the stock for YT3-850F, that would be helpful as well.

[Thinkpad Tablet General] 5T33Z0:
So, there's an OTA update for the x50f available. It's called yt3-x50f_s000023_161201_row and downloads 38MB.

[Thinkpad Tablet General] Medfordite:
I have the same issue, so I tried going through the last step in Post #52. It still fails. I am wondering if Lenovo is sending out a bad update.
[Thinkpad Tablet General] 5T33Z0:
I've uninstalled supersu as well as xposed framework and reflashed the boot.img from the latest Rom (S000022_160606) prior to this update but still no luck. In the official Lenovo Forums people who didn't even root their device (with verified integrity check) have reported the issue.

Upgrading from an earlier build (S000017 something) seems to work from what I've read so far. Kinda odd.
[Thinkpad Tablet General] Neo0:
Before I wrote the guide I tried this OTA stuff. In my experience reflashing the boot.img only didn't fix OTA. It seems like the system(.img) has to be untouched. No root, no xposed. Never.

hallo all,

can anyone advise on rooting tab 3 ?

thanks!

I will appreciate if you can advise on rooting this device, thanks !
[Thinkpad Tablet General] Shug69:
The link is for Kingroot 4.1. Have you tried 4.6?
[Thinkpad Tablet General] Zxian:
Picked up the Yoga Tab 3 8" last week. Loving the battery life and overall feed.

Kingroot v4.6.2 can successfully root this tablet. Verified with Root Validator from the play store.

Update: I have my Yoga Tab 3 with SuperSU installed.

Steps to accomplish:

Install Kingroot v4.6.2 - google for the latest link.

Run Kingroot and follow the instructions to achieve root. This will install Kingroot and some other app called Purity (ram cleaner? something, it's extra stuff I didn't want). Verify that you have root access with Root Validator or your other favorite tool.

Go to the following link and download the file Replace_Kingroot_With_SuperSU.zip from the link just below the video - make sure you get the updated version. - http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html

Watch the following video and follow the instructions. The script will fail some steps - this is ok! - Youtube - How to replace Kinguser with SuperSU

When you get to the point where SuperSU launches due to the script, it will ask to update the SU binary - Click Normal

When SuperSU asks to remove the other user management app, Click Cancel

When you click cancel, it should say that the binary was updated Successfully. Do not click Reboot!! Click Ok

At this point, check again using Root Validator. It should show multiple Superuser apps and a single Superuser binary (SuperSU)

Go back into SuperSU, and go to the options. Scroll down to the Cleanup section and select the option to remove the other user management app.

Check again using Root Validator. You should have only SuperSU installed.

Remove Purity using Titanium Backup or similar.

Now.... to get Xposed on here for Youtube Adaway...

Hi everyone.

I have YT3-850F. Is it possible to get a stock ROM for it somewhere? I've lost correct permissions for build.prop file and have KingRoot installed. So I've got a soft brick problem after restart. Of course I have no custom recovery :o only stock. There is only one solution to restore the device: use stock ROM with sideload. Could anybody provide factory_update.zip file for 850F? Many thanks, beforehand!!!!
[Thinkpad Tablet General] serhalo:
Same problem

I had a problem with my YT3-850F, trying to do a hard reset, just do not pluck more. I need the rom stock for this tablet. I have provisionally's running a rom I found on a Russian forum. This is the rom, remember that this tablet has 3 variants (F, L and M) ...

Hey. Did you have any luck with xposed?
[Thinkpad Tablet General] iddo123:
Well, I'm rooted using kingroot, but after I cleaned cache partition and dalvik (with root explorer) I still cannot get Nova Launcher to start after reboot, Nova works fine as the default launcher, but after I reboot only trebuchet starts :(

I noticed that Nova doesn't have "autorun" permission and trebuchet has it, but I cannot find how it might be possible to add such permission, and anyway that's probably irrelevant because Nova boots fine on other devices?

It'll be a pain to do a factory reset now that I already have everything installed, anyone knows how to get Nova to survive reboot, without doing factory reset?
[Thinkpad Tablet General] Zxian:
Sadly not. I ended up returning the device for now, since I wasn't able to get Xposed on here to get it working the way I wanted.

Hopefully someone can make a recovery for this device that we can use to properly root it and install Xposed. Modifying system files while the system is running is too risky IMO.
[Thinkpad Tablet General] traumatism:
Yeah it doesn't feel like it's yours until you can set it up the way you want it does it. I'm sticking with it for now and waiting to see if they manage to get xposed to work with it. Until then i'll keep it as is. Thanks for the update bud.

Purchase recommendations

Hi, I'm new here! I bought two of these for the kids for xmas, and I must say, they are looking good. It is also good that they seem rootable!

I'm considering getting one for myself, either this version with the Snapdragon chip or the Pro version (with the Atom, but without LTE).

It would have been wonderful to have Cyanogenmod or a similar custom ROM on it at some point, and then I came across and article, which I am prevented from linking to (the title was "MWC 2015: Cyanogen teams up with Qualcomm Snapdragon to improve Android fork experience"), which might indicate it is the Snapdragon version is the closest to that goal.

What do you think, is the Snapdragon or the Atom version most likely to get e.g. Cyanogenmod?
[Thinkpad Tablet General] traumatism:
Just as a query and a heads up. Since rooting the latest auto update failed and I had to do a factory reset on my device. Any ideas?

If you are yet to experience this I'd recommend getting titanium backup and freezing the system update service. Best way to do this is reset the device to factory and skip the WiFi login option and skip through to the home screen.

Once there then log in to WiFi. Wait for the system update notification to appear and select it and cancel the download. Make sure it isn't downloading and then log into Google and get titanium backup from the app store and freeze the service.

To check it worked go into about device and try to open system update. Clicking it should do nothing

TWRP

If you wanna have TWRP for Yoga 3 10" you can get it from lenovo russian forums. It for YT3-X50M/L but works fine on mine tab 3. Just I have to disable screen lock (freeses). Evriting works fine (wipe, restore, backup, mount sideload and so on). It got some extended options (backup modem, efs, insaoll img not only zip). you figure out yourself. Need to register for downloads and not go to English forum - it in russian forum.

A different experience

I had a slightly different experience. I received the OTA update (YT3-850F_S000027_151217_ROW) and I attempted to install it but was not successful. I did not had to factory reset my tab. My tab just restarted back to the way it was before attempt to install.

The install error I got was:

Finding update package. . .

Opening update package. . .

Verifying update package. . .

Installing update. . .

Verifying current system. . .

/dev/block/bootdevice/by-name/system has been remounted R/W; reflash device to reenable OTA updates

E:Error in @/cache/recovery/block.map

(Status 7)

Installation aborted

Anyone knows how to overcome this error and what it means? I guess I could unroot SuperSU, then install OTA update, reroot with Kingroot, then replace with SuperSU again, but this seems a lot of work (not to mention may not be successful not knowing what the content of the newest update pkg contains).

Thanks in advance for any insights.

How long did it take for yours to load after the install attempt?

|Sent from the bowels of my crypt|
[Thinkpad Tablet General] Medfordite:
As a FYI if you want to use it that way, the firmware listed in post 52 is no longer on the file hosting site, but a quick Google got me on the Russian site to be able to download it.

http://www.mediafire.com/file/yjyeafxwdp8zdsr/YT3-X50F_S017_151023_ROW_QFIL.rar - is where I found mine.

I am writing this as it updates so we can see the progression to the Android 6 update from the above file:

This firmware will install a version which prompts for the update which is around 36mb. That ran perfect 'out of the box'.

There is a batch file that I found in there called:

8909_fastboot_all_images.bat

I took a chance and risked bricking the device, but it appeared to run okay and rebooted my tablet.

The initial boot took about 4 minutes from flash.

After this reboot, I was presented with around a 350mb download after checking for updates.

To: YT3-X50F-S000019_151223_ROW

This took roughly 15 minutes to install, but considering the size of the update, I can see why. This Installed w/o erasing my data. :)

Then I was presented with a 44mb file to update to:

YT3-X50F_S000020_160216_ROW

This took about 8 or so minutes to install.

Now a new update:

YT3-X50F_S000020_160216_ROW to YT3-X50F_S000021_160314_ROW (52MB)

This seemed to take around 10 minutes to install this time.

Another Update:

YT3-X50F_S000021_160314_ROW to YT3-X50F_S000022_160606_ROW (39MB)

(I think I have caught on to their numbering scheme in the versions - the last set of numbers are YYMMDD) Good to know if you are searching the web for the firmware, you can probably zero in on that version.

10-15 minutes later update finishes.

Getting closer....

YT3-X50F_S000022_160606_ROW to YT3-X50F_S000023_161201_ROW (38MB)

Having been rooted from day 1 of ownership on this tablet (Early Spring of '16), I never realized how many OTA's have come by that I missed. Not sure if that is a good thing or not.

Now on to the next update:

Very interesting pop up with red bold text warning about erasing my data and being sure I have good backup.

Go to the update and it is showing

YT3-X50F_S000023_161201_ROW (992MB) and mentions Android 6.0 - something I did not see these last few days of trying to update.

Update is running (30 minutes in so far) - I'll bet it is going to install, so anyone else who is facing the OTA issue, this is the method I am running and looks like it will work.
[Thinkpad Tablet General] Neo0:
So there is Android 6 rolling out for X50F? That's nice. I've never expected to see a major system update on this tab. Thank you for posting another firmware link. I would have uploaded the stuff somewhere else but my Internet connection is to damn slow...

[Thinkpad Tablet General] 5T33Z0:
I reflashed S000022 via QFIL and now the the installation of the OTA update for the X50F works. It takes quite a long time to install for an update that's only 38 MB in size.

It seems to be the only way to makr it work. I tried booting into twrp before and manually flashing the update zip but that didn't work.

But I have the otaupdate.zip if someone needs it.

Edit: I am kinda pissed now. I went through all this trouble to update the tablet only to realize that it's still on Android 5.1.1...

Edit 2: I see that's only 1 step of the process. Next, there's another update called S000114_161221_row which is 992 MB in size

Can someone post 850M links?
[Thinkpad Tablet General] SM-T325 LTE:
Curious: where did you get the OTA file? Did you manage to get it from your own device after downloading but prior to installation? If so, were you rooted? Unlikely, I realize, if you got the OTA update "OTA" but I'm still trying to snag my OTA update before installing on my NOT rooted YT3-850L. Thanks.
[Thinkpad Tablet General] 5T33Z0:
Yes, i grabbed the small 5.1.1 upfate after downloading, prior to trying to installing when the device was still rooted.

OTA are located at Data >Data > com.lenovo.ota > app_otapackages so you can't access that folder without root. I tried via PC as well. No chance. Maybe there's a way to grab it via ADB, but I don't know anything about that.

I guess someone will upload it in a couple of days somewhere.
[Thinkpad Tablet General] Neo0:
For those who have problems installing OTA updates even after reflashing system, recovery, boot and userdata, try using the "8909_fastboot_all_images.bat" which is located in the firmware folder. I were able to get rid of the "Status 7" error this way.

Your tablet will be wiped and all partitions will be flashed to stock.

I had problems using the .bat because adb.exe and fastboot.exe were not in the same directory as the .bat-file. After copying them over from my adb-directory it started to work.

If you only see a black window which diasappears quickly after executing the .bat-file, right click on the .bat, chosse edit and put a "pause" (without "") at the end of the file. This will print a "Press any key to continue..." message before closing the cmd window so you are able to see any error messages.

Edit: For those who don't want to copy over stuff this adb installer might be usefull as it's able to install adb/fastboot system wide
[Thinkpad Tablet General] SM-T325 LTE:
Sounds as if I might be able to DOWNLOAD w/o INSTALLING the 6.0 OTA update, ROOT, and then grab the OTA and THEN apply it after UNROOTING? Haven't rooted THIS device as yet, because of ongoing efforts which require (AFAIK) a non-rooted device. I can't see the relevant folders w ADB and "ADB logcat" doesn't give me the actual download url, either.
