Anyone got a copy of the build in December? I wanted to test to see if the new firmware cause the slower transfer speed between Android devices .
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] thorazine74:
Not sure what you are trying to test, but don't think that downgrading builds would be a good test for anything caused by the firmware upgrade, wouldn't you need to downgrade firmware for that?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] toanau:
That's true. Ever since the up graded firmware I have terrible transfer speed transferring between devices. Wifi download speed is good
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Gomezie:
You guys planning to build 15.1 at some point? This is not an ETA request, just Figure it would require kernel sources or something?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
Yes, but I am not personally involved in it yet. There are people working on it at the moment, but I don't have the time to help just yet.

Updated kernel sources would certainly help with this, but I don't think they are strictly necessary.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] matshias:
Very hard for us to do anything about the DRM situation since we (the devs here) lost our DRM keys. So any modification we do that would fix it has no effect on our devices. The latest build contains some changes which could fix it but there is no way to know for us. I know that this is an unsatisfactory situation but with all the DRM **** happening behind closed doors in the protected trust zone (QSEE) it is nearly impossible to debug what is going wrong.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] matshias:
The setup wizard crash is caused by the open gapps. If you wipe system then flash Lineage and boot into the system it is working fine. You can flash open gapps later on. I suspect that the open gapps packages are not ready for Android 7.1.2 or the latest Lineage changes.

Regarding the camera, for me it is working stable if I reboot again after it crashed. We are looking into this but it it will take some time.

Thanks!, i'm staying with the 31 march build, works pretty good!, i'm using Google Camera and i think is better than the stock one! ?

[MENTION=2806083]DerEineDa[/MENTION]:

Could you add the following SE-Linux rules, please:

#============= vold ==============
allow vold adsprpcd_file:dir { ioctl open read };
allow vold block_device:blk_file { open read write };

The first is somehow audio related, but the second is really important. Otherwise the system can't access the partition with the decryption key, i.e. it can't decrypt or encrypt the data-partition.

And another request: Is it possible to rotate the default orientation 90°? So I don't have to pick up and rotate the tablet by myself,when it's standing on the table and I have to input the decryption password? :)
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] matshias:
Thanks for the hint with the decryption! We will add the two rules for the next build.

Regarding the 90 deg default rotation we haven't found a way yet which doesn't involve modifying the framework and boot animation code itself (which works well though). There doesn't seem to be a build.prop option for this which also rotates the sensor inputs so that display and inputs are consistent. If you have an idea how to do this properly we're all ears.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
Great, thanks! :good:

Yes.. I got that far, too.. but I don't have a full build environment set up right now. But the boot animation rotates fine, just not the touchscreen. It's a bug or missing feature of Lineage. We could either patch the Android input system, directly the kernel or, as you said the framework. If you want to become official, we would have to write a general fix (there is some for older Android versions) and hope Lineage accepts it..

And what about TWRP? Can you rotate that too, easily? :confused:

Btw, why are there two Synaptics touch-drivers in the kernel sources? Have you added the second one? I'm wondering if the panel supports nice features like douple-tap-2-wake (really missing that) and gestures. The drivers also have options for flipping and swapping the axis.. :cool:
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I've looked into dt2w. If I remember correctly, we are using some sort of "v2"-driver (don't remember the exact name) that doesn't have an option to activate dt2w. It bothers me, too.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
Mhh, it seems to have that feature, but it needs a lot of additional code to get it actually working. I'll lock into that...
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] hotsauce81:
Hi. Thanks for the great rom.

Is it possible to turn off the notification light?

Also is battery performing lover on this rom than stock?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
The option to disable the LED is located at:

Settings -> Notifications -> Press the small gearwheel at the top right -> disable "Pulse notification light"

This should disable the notification LED completely.

In my experience, battery life of this ROM is superior to the original firmware.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] NY1M6gTOR3Rj6AGKXTcx:
I might be wrong, but this doesn't disable charging light.

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] vladimiroltean:
Looking to get the LTE variant of this tablet (X703L), however I can't seem to find it anywhere on sale in Europe, just the wifi one? Is there any online shop in Germany or UK that I'm missing?

What method did you guys use to collect kernel boot logs from the device during bring-up?

I guess nobody pinpointed so far what wipes the DRM keys, but it's not bootloader unlocking and not TWRP + LineageOS flashing?

Is there any other tablet available that does a better job of supporting stock Android Nougat? However cool your Nougat porting effort might be, I'm still reluctant to place so much money on a manufacturer with such mentality as Lenovo. They literally couldn't care less about leaving customers out in the cold with software support. Can't really blame them either, when more or less the whole industry does the same thing..
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
I got the rotation working! It needs a kernel patch, a build.prop entry and a changed config in etc. The only thing that still needs to be rotated is the camera.

I've looked into it, seems that our device lacks firmware support for real dt2w.. :(

Maybe there is a workaround, but it would need a lot of time to implement it.

I wrote a new kernel config, to improve performance, memory management, the camera and I fixed a security hole. Do you have something like a Telegram or Whatsapp group where we can discuss this stuff? :)
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] matshias:
Yes exFat is included in the kernel.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] matshias:
I totally hear you. You can go with the Galaxy Tab S2 which has official Lineage 14.1 support. But Samsung ... ;)

Regarding DRM keys, yes we're still in the dark about that one.

The bring up took a bit of time and it was more like trial and error. We had a bootloop in the beginning, so I put endless loops in init and kernel to see what goes wrong.

Camera and Skype issues

Hi all, some feedback from the latest ROM.

Only issue I found is the front camera not working and Skype calls with no camera whatsoever. Not even the rear one.

I hope this helps.

To the people having Wi-Fi issues and willing to try out an experimental build. I am somewhat in the blind, as for me, the experimental build works just as fine as the latest official.

I have updated the wlan kernel driver to the newest available version from Qualcomm/CAF. Builds are available for the YTX703L and YTX703F.

1. I don't care about anything else not working properly in this build, except Wi-Fi.

2. Please, clean flashing only (wipe your /data before installing this build).

3. Please watch your wlan0 interface's MAC address before and after flashing this image, and tell me if the MAC changes.

If you find something that doesn't work as expected for you, please be as descriptive as possible, and also include your country code and a "dmesg" and "logcat" in your reports.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] sen1996:
my tablet cannot connect to PC after flash the rom.

The computer prompts the unrecognized usb device.

I've updated the drive many times, and it still does.

Is it a bug？

Is there any solution？
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] vladimiroltean:
Hello and welcome to the forum.

What device (F or L), what build are you talking about? What host OS (Windows 7, 10)?

Also, what have you tried, exactly? DId you go to the Notifications area -> tap "USB charging this device" -> select "Transfer files"? What happened when you did that?

To put it bluntly, the "bug" you are referring to does not ring any bell.

Hello [MENTION=411194]BlackAfghan[/MENTION]

Did you ever get the time to look into the charging and otg at the same time?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
Yes and it is possible, but needs changes of the driver, used for the USB controller. And it is not clear which one will be used in future, so it is on hold for now... Sorry, can't tell you how long it will take, but months at least, since their are more pressing issues at the moment.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] sen1996:
Thanks for your welcome and I'm very sorry to trouble you.

My tablet version is L, and the system is the latest lineageOS 14.1. I have tried various methods on the Internet,and tried to connect to other computers, but it still doesn't work.

But I have found a solution. The problem is from the computer, not the rom of tablet. I tried to uninstall the computer's recent system updates.Happily, it works.

I like the rom very much.I am sorry to mistake this for a system bug as it was my first time to flash this rom.Thank you very much for your efforts and thank you for replying to me in your busy schedule.

I hope you will keep doing it and I will always support you.Please forgive me for my poor English.

Stock has terrible battery life. It's night and day comparing to this Rom
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Fudgemond:
Hmmm, I've looked at the specs on the Lenovo site as well as GSM Arena and the only Bluetooth mentioned is 4.0, A2DP, no BLE that I can see. I definitely have BLE on my phone and it instantly connects to the device. I have installed BLE scanner and it works but I just cannot get the Yoga to connect to my indoor training device.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Finefeather:
I am not criticizing this ROM.

Battery life is not something you can compare successfully between different users. It depends on too many variables. One of the most misunderstood and left out variables is the battery itself...and the device charging circuit...and the user charging method. OF course battery life generally is a result of activity or amp draw and can be the result of a bad ROM and hundreds of other things, but the original coders of OS firmware, kernels and software like Android for phones are very aware of this and are usually not the cause of bad battery life...so the main cause of battery drain is probably third part system development by different phone manufacturers, and badly written apps, and mostly radio standby and background internet usage. A good battery usage app, on most new android ROMs, can give good indication of the culprits, but even then it might be that app you use every day which eats up your battery...every man for himself...oh yes and the ladies as well :)

There is also an unroot option in the supersu app settings which I did not try yet.

And also I readed about flashing the original boot.img to uninstall the supersu, but I don't have this boot.img and I feel a bit unsecure to risk this.

[MENTION=2806083]DerEineDa[/MENTION] can you help me? Thanks
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] thorazine74:
I think you would need to do that but I haven't really tried.

Also I think if you reflash the ROM after formatting the system partition you will also clean any remains of supersu root. (it's all in the system and boot partitions, right? Which both are reflashed in the ROM's zip)
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
Thanks for your help. I want to avoid formatting the system and not to loose all my apps and configurations. I have a TWRP backup, but with the supersu issues.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] cartman56:
finally. it works great thanks?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] thorazine74:
Someone correct me if I'm wrong, but wiping (not formatting) the /system partition would not make you lose your apps configuration, those are on the /data partition.

I'm not sure how SuperSu reinstalls itself nowadays, but if it's still using an addon.d script, deleting it and re flashing the rom could be an option too.

Not sure but SuperSu does not change anything in the data partition that would not erased when you uninstall the apk.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
thanks a lot for your help, i did now this way as you suggested:

1) uninstalled supersu app with SD Maid Pro

2) restart to TWRP and installed the last rom (from 24.02.2018) and added in the same process the Magisk 16.0 zip-file and flashed all together

3) rebooted to system without any issue and installed the Magisk Manager v5.6.2) and you can see the results on the picture (even passed the SafetyNet Test without problems).

Very good, now i can hide my Sky Go app - once more thanks a lot.

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DeathHacker:
Probably not, the devs usually prefer to build from the most "vanilla" LineageOS source, so a modification like that will probably not happen.

Hi all,

So I installed the ROM way back, but seeing that the LTE variant made it to the main page - thank you [MENTION=7398554]vladimiroltean[/MENTION] and [MENTION=2806083]DerEineDa[/MENTION] - I had to update.

Writing to report the update went well ( I jumped from the first test build that [MENTION=7398554]vladimiroltean[/MENTION] posted ) although I dirty flashed.

Battery life is incredible. Same is performance.

One problem I now have, the 2.4 GHz wireless only goes up to 5.3MB/s. It use to go 12.x with the old build. 5ghz is not affected, goes up to 34 like before.

Also, I installed kernel auditor and played arround with the governor. Must say I am happy with the results. Is there any plan to do a custom kernel?

Also is there any hotplug driver in the kernel? Configurable I mean? I think I can squeeze even more battery out if can make the big cores go offline.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DeathHacker:
With kernel auditor you should be able to modify qcom's hotplugging system's values.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
[MENTION=8248855]DeathHacker[/MENTION] is absolutely right. I want to focus on vanilla LineageOS and a non-bull**** kernel. You could say that compatibility and stability are the biggest focus for me.

Of course, other developers are very welcome to fork our repos and base their custom roms and kernels on them!
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] misha0209:
That was what I thought, but I just can not find the menu.

Maybe you can tell me where I may find the menu if you know. Or if you know of an app that allows me to do the same as kernel auditor, please name it. I want to configure governor, io for internal and external storage and hotplug.

Thanks for the input!

Well I'm sorry to hear this, but I can understand where you're coming from, and I somehow appreciate you want to keep the ROM stable and clean. You are doing a damn good job at it :D

Let me rephrase, any chance you consider doing an add-on, like a flashable kernel, that people can flash if they so choose? I guess not but i had to ask.

Would you be aware of anybody having done something like that so far?

Am I the only one getting a hiss from his earphones when listening to music on low volume?

It might not be related to the ROM or firmware but it's more prevalent when having Dolby Atmos on so it just gets me wondering if there might be something wrong.

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Felheipe:
There is something wrong with the sound for sure. It's more noticible when listening at low volumes to calm music(classic and jazz). There is a constant hissing that drowns the sound. Once you get the volume louder you still hear the hissing but it's kind of overpowered by everything else.

I tried downgrading Dolby Atmos to see if it would make a difference and it didn't, nor do I believe this to be a problem with my earphones since I've tried it with multiple ones.

Could it be a issue with the firmware?
