ok guys , Right now I am downloading that YT3-X50M_USR_S017_151002_ROW_QFIL.rar and report back . I don't know if it will be today though.

anybody else was able to download from that silly place where they ask you to fill up surveys ? http://upgrade-marshmallow.net/upgrade-update-lenovo-yoga-tab-3-8-0/

[MENTION=243942]Noonski[/MENTION] , what make you think that these files are Marsmallow ? You've seen it in the page that brought you to this download link ? I want to make sure before i install this...and it's a bit scary to install a mobile version on a non mobile tablet.

-----

some file in the bunch like the one name OTA date from ‎October ‎2, ‎2015, ‏‎ isn't it a bit early for marshmallow on the yoga ?

as seen on the lenovo page the update to lollipop, for the yoga 2, was around that date Android 5.0 Lollipop July 2015
[Thinkpad Tablet General] Noonski:
Maybe I was unclear. But i never said i thought they where Marshmallow. My question is exactly as your concern. What happens when you flash the (M)obile version to the (L)TE version.

1. Does the M version rely on hardware like extra microphone & voice modem.

2. Or does the L version actually already have all the needed hardware and the M software version automagicly enables voice calling. Which i suspect is not the case,, but I hope it might.

Slight edit. the L version already has a dedicated mike at the bottom...
[Thinkpad Tablet General] zigonneux:
anyway, if someone finally get a marshmallow rom for the yoga tab 3 , keep us informed. It look like nobody has got that MM6 rom from where we have to fill up tons of surveys before downloading it ...

Hello.

What program U use to load firmware rom from computer to tab?

Best.
[Thinkpad Tablet General] Neo0:
To install the firmware you'll have to use fastboot
[Thinkpad Tablet General] pasza_sadyka:
:eek: How can i do that? Step-by-step please :)

Instruction in 1 post? "update from SD card"?

But i need unpack rar or zip file? Inside catalog or directly to sdcard? There is a lot. img files. Format card to fat32?
[Thinkpad Tablet General] zigonneux:
usually there is a tool to update the rom in the packages. No need to unzip the image but unzip the whole package to see if there is the drivers for your PC so that you could use adb fastboot and I've seen a tool to flash a rom in some packages... There is also a TWRP to use with the Yoga 3 . Sorry but you will have to do some reading. We talk about it in this thread.

As to find out how to use adb fastboot : there is a search option up there in the forum.

So there are a few ways to flash a rom on this device.

I can tell you this much :

Some ROMs have added features that are available to flash.

To Flash the App/Rom Feature you must first download the .zip file.

Mount your devices SD card and copy the .zip file over.

Boot up to your devices custom recovery.

Wipe your Dalvik-Cache in the Wipe Menu. And then go back to the recovery's main menu.

This step may vary per device, there should be an option that says "Flash .zip from SD Card", select it.

Select the .zip file you wish to flash.

Confirm flashing of .zip file.

Wait for the file to flash; and if successful, reboot.

[Thinkpad Tablet General] zigonneux:
does it really matter ! I've installed kingroot and I can delete the lenovo stuff and keep the important stuff... this thing work fine on 5.1.1 and is not expensive enough to pay someone to fix a rom for it. This is why there are none yet.
[Thinkpad Tablet General] bisontes:
It matters to me.

The performance of this tablet could be improves in topics such as speed. It has a latency/lag issue that I'm pretty sure is softeare and not hardware related.

Also, I didn't find it that cheap and I don't have money to buy me another. But I could put $15 in a collective effort.

Cheers.
[Thinkpad Tablet General] zigonneux:
well, the cpu on this tablet is a low performance CPU/GPU , somewhat the same as the nexus 7 1st generation. More i think about it, it's true that a custom Rom boosted the speed of my old nexus, therefore the same could happen to the Yoga Tab.

So, I've changed my mind and I'd put a $15 on it too. :good:
[Thinkpad Tablet General] ShintaFreeman:
This tablet works excellent with Android 5.1.1 but I'm curious about running another version, just for fun. So, here's my $15 too ;)

It is necessary to make QCN backup before root or flash? Yoga 3 model yt3-850L /LTE only/.
[Thinkpad Tablet General] zigonneux:
before root no backup is necessary. Before a flash a backup is always mandatory.

---------- Post added at 10:24 AM ---------- Previous post was at 10:19 AM ----------

Just to say, when you write in blue like this, we almost don't see anything if we use the black theme of the forum. Many people use the dark theme so, it's better to keep the writing to default.

On another note, I've been talking about Rom and the yoga to a coder here in the forum, and he said that if he had a yoga tablet he would build a Rom.

[Thinkpad Tablet General] zigonneux:
I just post what I read, I haven't tried yet. I wish i could help you further but my knowledge about playing with the yoga recovery is limited.

I know that we can install TWRP on it and therefore make a backup with it, but you would have to read many posts in this thread to find out where it is and how to do it.

But still don't know that F works on L or M model. Or firmware from M works on L. /on F works perfect/.
[Thinkpad Tablet General] zigonneux:
l or m = mobile lte . The F is a simple yoga tab 8 . If if you flash a F on a mobile l or M, mobile won't work. That's about it. The rest is the same, so the "drivers"won't be applied.
[Thinkpad Tablet General] pasza_sadyka:
So U thik the firmware from 850M will work on 850L with mobile? I have qcn file backup from 850L - will work on 850M firmware if something go wrong?
[Thinkpad Tablet General] zigonneux:
I wouldn't know for sure. But if you flash it, the worst case is that it won't boot... as long as you can go back to TWRP you're fine. If you don't have a OS on your tablet at the moment, you don't have much to lose . BUT I'm no expert with the yoga tablet.

[Thinkpad Tablet General] SM-T325 LTE:
AFAIK, your last post about this is the last anyone's said about the L->M version business. I've got an YT3-850L on order, and thought it would have the phone feature and only now realize it does not. So, I'm wondering the same thing but am guessing that just flashing the M firmware would NOT give you a built-in phone on an L version. Hope I'm wrong. Separately, I have the Samsung SM-T325, which DOES have the built-in phone. A nice feature when you want a speaker phone. It would be a little absurd to hold up to one's ear, but can serve fine via a headset, wired or BT. Do please let us know if you've found out any more about this L->M question.

FWIW: I'm aware of NO tablets released for the US-market with built-in phone capability. No idea why. You have to shop the international market, which you already do. This is certainly true of the Lenovo Yoga tablet series. I found an India-market Yoga Tablet 2 three or four years ago, and had it in my hands, but unlike the advertised specs for the Tablet 3 "L" model, that one had very limited GSM/3G/4G bands and wouldn't work as a world phone (though would be fine in India). The Tablet 3YT3-850-L at least seems to offer ALL of the bands, including T-Mobile's oddball 1700/2100 split up-link/down-link Band 4. Or, so I hope. I'll know soon.

SERHALO:

I've got a YT3-850L, so can't help with the "F" ROM. But, I'm curious: You actually installed the "M" variant ROM on your "F" tablet and it ran OK? Might I ask HOW you did that? AFTER rooting? Or to an UNROOTED tablet? There are several folks wondering if the "M" ROM will "convert" an "L" tablet to an "M" with native phone support, since the "L" has a SIM card slot. I think NOT, but am curious what non-working "features" showed up on your "F" tablet with the "M" ROM installed. I suppose a non-working PHONE/DIALER. Thanks!

[Thinkpad Tablet General] 5T33Z0:
Hi, I picked up the yoga 3 10.1 inch (x50f) from Amazon and I got pretty confused that there's nit a dedicated section for the different Models of Lenovo tablets at all.

So after looking through a lot of posts I finally managed to unlock the bootloader, get root and install xposed framework.

So then I was looking for any Roms and it kinda caught me by surprise that there aren't any. Not even Stock Roms. Odd...

But I saw more threads about the YT 3 8 inch and the YT3 Pro and I am wondering are they are compatible as far as the Roms are concerned?
[Thinkpad Tablet General] SM-T325 LTE:
There ARE ROMs, but you really have to scrounge to find them. At least for the "F" and "M" versions. I STILL haven't found the "L" version which matches mine. There's a 5.1.1 version posted on the Levovo Russian site, and another on a rather odd site about which there is nearly NO INFO (see "TeamAndroiders" dot com). I'm 99% sure that the PRO and non-PRO ROMs are incompatible. There are very different hardware platforms (with very different prices.

BUT, I'm VERY interested in a step-wise account of HOW, PRECISELY you managed to get your Yoga Tablet rooted. I'm still dithering on this, probably waiting until after the announced DECEMBER 6.0 update. From what I can tell, the "M" ROM should flash to my "L" tablet, but probably shouldn't be applied to your "F" version, since it has no SIM slot. Word has it that the "L" can be "converted" to the "M" as the ROM is (supposedly) the only difference. I'm still sitting on the edge for now. I rather like my Yoga tablet and don't want to trash it whilst trying to make it better. I've rooted all of my prior android devices (including my KNOX-equipped Samsung tablet), but am a little hesitant on this device because, like you said, there's little dedicated support for these tablets.

So, please, consider a new threat detailing your success in rooting YOUR Yoga. Thanks.
[Thinkpad Tablet General] 5T33Z0:
Wow, thanks for that detailed answer. Very informative.

Let me try to retrace the approach I took to root my Yoga. DONT Follow this step-by-step. Because it's convoluted, probably dangerous and highly unprofessional ;)

1. I used KingRoot to get root. But I didnt like that because it runs a lot of stuff I didn't like

2. Then I found an app that should replace KingRoot with super su. It's called supersume. But that didn't work. But I found a blogpost which dealt with the same subject of replacing an app similar to kingroot with superuser. So I downloaded his package and flashed it via ADB (after installing the necessary drivers on pc) It removed kingroot but gave me an error because it was written for removing a similar app with a different name. Nonetheless, it removed kingroot and installed superuser.

3. Next, I installed supersu via play Store and it said, hey, there's another root app present you should remove - shall i replace it? Yup. It uninstalled it updated the binary and then i was good on the root side of things.

4. Then I searched for a fitting TWRP image and found one from a russian forum (TWRP-2.8.7.7_YT3-X50M) and flashed it. DON'T DO THAT (YET) It kills the stock recovery if the bootloader is not unlocked which I forgot. So I was left without recovery which made me kinda nervous.

5. So then I had to use the PC to unlock the bootloader via adb (following OPs instructions)

6. Flashed the twrp.img via adb too

7. Then the tablet restarted into recovery and ran a script (which wiped the whole thing) and then rebooted again

8. After that everything was cool.
[Thinkpad Tablet General] SM-T325 LTE:
Thanks. I've stayed away from KingRoot. Seemed way too sketchy. Glad it worked for you but I want to avoid that approach if I can. Which may mean no root for me...

5T33Z0,

"I spotted a new Android 6 Rom for the YT3L/M on the Russian Lenovo Forums.

Version is: YT3-X50M_S000127_161124_ROW”

What would you do with it if you had it? Do you own a YT3-850L or M? The ROM cited appeared to be for the M model. The thought is that flashing it to an L model would turn it into an M. Not confirmed. But it definitely would not do that with the F model.
[Thinkpad Tablet General] 5T33Z0:
I'd probably try flashing it. I have the F Model. But I think that besides the missing sim card slot and the LTE capabilities they don't seem to be different. I even found all the phone related stuff in my F-Rom. Since flashing the M Recovery worked, this might as well, too.

But there's an Android 6 update for the F announced for December as well so I probably wait for that. It's kinda lane that Lenovo Russia is the only official support forum that provides Rom downloads. The rest have to use this program for PC - smart install or something. I guess OTA is no longer possible after I installed TWRP, right?

Firmware for YT3-X50F

I recently soft-bricked my Yoga Tab (the bootloader was still ok), but was unable to recover b/c it proved to be very difficult to get a factory image for this tablet, so I had nothing to recover from.

Recently I was able to locate a compatible image on Lenovo's chinese support site, with the help of a kind Internet denizen, who responded to my call for help here:

[Thinkpad Tablet General] TheAvatar:
I tried to modify the X50M firmware to go on to the YT3-850F, never attempted this before so it failed.

But I will play around and see if I can get it going.

EDIT: Derp, it's an OTA... not going to happen... I did spot the MM OTA for the 850M on the russian forum so I will see if I can get that installed.
[Thinkpad Tablet General] 5T33Z0:
DON'T DO IT!!!

I flashed that 850M Android 6 Firmware from the russian Forum via TWRP and it rebooted successfully!

BUT:

1. I lost Root

2. Lost TWRP

3. The Tablet did start and run

4. After installing some Apps, however and shutting it down, it did no longer start

5. A Factory Reset got it back to booting again, but what good is that, right? It's probably not a big deal to fix it, but I am not a dev and don't know anything about coding.

6. So I reverted to a Firmware for the 850F (which worked before) BUUUT that left my sreen black ("Doe!") :D

7. So I had to download YT3-X50F_S000022_160606_ROW_qpst from the Russian Forum as well and Flash it via QFIL

and kept my fingers crossed.

It worked and now everything is back to normal and I am going to wait for the offical Release.

[Thinkpad Tablet General] SM-T325 LTE:
May we assume that your device is the YT3-850F and NOT the YT3-850M or YT3-850L? I've got the "L" and and thinking of flashing the "M" from from the same site, but am, shall I say, hesitant? I'm really hoping someone with the "L" model will do what YOU did with your (I'm assuming) "F" model.

Thanks for posting and warning. Doesn't sound like this ROM was a fit for the "F" variant.
[Thinkpad Tablet General] 5T33Z0:
There's nothing to assume. I mentioned more than once before that I was going to flash the M Firmware of Android 6 on my F Model on purpose. ;)

Besides the reboot not working it was actually working. I am pretty sure, someone who knows his way around in coding can easily make it work.

Found a pretty simple rooting process after restoring the tablet without replacing the original recovery.

0. Copy twrp.img from Russian forum and supersu.zip (any) to tablet

1. Unlock bootloader via fastboot

2. Run (don't flash) twrp via fastboot (read only)

3. Flash supersu, wipe cache/dalvik

4. Reboot. Done

Side note: that QFIL tool from Qualcomm is really good for rescuing your device if it gets softbricked (as long as you find the right firmware with "qpst" in the filename. It's usually packed in 7zip format).
