Lenovo Tab P11 Wi-Fi (TB-J606F) 0906 Kernel Source

2021-10-17, 5:18 AM

Hello. I had recently bought a tablet computer running Android (Linux Distribution) from Lenovo, which the model name is "Lenovo Tab P11", TB-J606F.

 

I could find the kernel source from Lenovo Open source site, but this seems to be outdated and does not match the prebuilt binary kernel packaged onto the latest stock firmware.


The latest stock firmware is TB-J606F_S120228_210906_ROW.zip, but their latest "Open Source" package is tb-j606f_opensource_s100044_201118_row.
This shows that the opensource package is the one for stock firmware s100044 from 2020/11/18, while the latest fw is version s120228 from 2021/09/06.

There's of course, the chance that the kernel may not had changed. I also checked this.
First, the defconfig most similar from the one extracted from stock fw's Image.gz was the "m11_row_wifi-perf_defconfig" .
I first built with that defconfig, found touch sensor not working, and also the graphic driver causing glitches on the screen.
I then built the kernel again with the defconfig extracted from the stock fw's Image.gz and the same issues happened.
Thus, I believe that the kernel source is not identical to the Image.gz on the latest stock firmware.

 

I do know that it is often easy to forget releasing the kernel source when manufacturers release a newer firmware.

However, as using the GPLv2 on the linux kernel, manufacturer lenovo should release the source code of the kernel as soon as possible.

 

Thus, I write to lenovo, to please release the latest kernel source of firmware 0906, which would then be probably named "tb-j606f_opensource_s120228_210906_row.gz".


Thanks, and best regards,
HexagonWin

Welcome to the Community Forums @ HexagonWin !

 

Thanks for posting here!

 

Please share here your Lenovo Tab P11's MTM (machine type-model) number for us to check its specifications as this would help us detail more about your machine variant while keeping the confidentiality of your serial number.

 

It can be seen through the device's label/sticker or its original packaging and does usually have a format of Z********R as an example.

 

Here's a link as well that also contains additional methods in obtaining your device's details.

 

Thanks,

Adriel_Lenovo

Hello.

My device is the XiaoxinPad, which I bought from China. (4GB Ram / 64GB Storage)

The model number is TB-J606F, which is the same and identical as the Lenovo P11. (The Lenovo Open Source kernel package also has the model name TB-J606F on the file name.)

MOD: Serial number removed as it's a privacy risk on a public forum - Doc

Best regards,

HexagonWin

Thanks for responding @ HexagonWin !

 

About your concern, we only recommend to use the Rescue and Smart Assistant tool to see if you can re-flash your Tab P11's Android OS.

 

The Rescue and Smart Assistant tool can be downloaded/installed using a Windows PC or laptop so that you can plug the Tab P11 into it afterwards.

 

Make sure to backup your files first to avoid data loss.

Please click on this link to download the Rescue and Smart Assistant tool itself.

 

Thanks,

Hello, thanks for the reply, @Adriel_lenovo.

 

I'm sorry but which concern do you mean? The only concern I have is about the kernel source, not the firmware.

I would use the tool that you recommended later when I am restoring my tablet, thank you for mentioning it.

However, what I asked for on my previous post was about the newest kernel source of the TB-J606F S120228 firmware.

Because the Linux kernel is licensed under GPLv2, Lenovo has the responsibility to provide the source code for the kernel.

I believe that you had checked my serial number to ensure that my device is the actual TB-J606F, however, even if I do not have the device, as the firmware is available, the source code also needs to be available.

 

Thanks and best regards,

HexagonWin

@Adriel_lenovo I am very disappointed that Lenovo, the 2nd biggest computer company in the world, is not following the GPL correctly and is not releasing the kernel source, and is even ignoring our community's comments of declaring to release the kernel source. I say again, Please release the kernel source.
