Development [ROM] [UNOFFICIAL] [12.1.0] [TB-J607F] Evolution X Snow

[LegendOcta]

Please make Evolution X happen to TB-J606F also! it's with an older SOC, and we don't get A12 update. A lot of people have it, but not much support

The most important : He/she doesn't have it.
Also, Lenovo's kernel source is REALLY crappy for the J606F.
As a owner of j606f I tried using their kernel source code, which lacks update since the android 10 0906 firmware, and so it has much lower version than android 11 firmware's one (might not even boot in And11 bootloader? I didn't upgrade), doesn't support Novatek touchscreen, some things like that.
It would be plenty of work to make it working. Although. both shares plenty of peripherals.. I don't expect getting a source-built version of these roms in my J606..

After flashing the patched boot image, the sound stops working. Any thoughts on how this can be fixed?

upd. solved

you can flash google gsi (android 12), its works good.

just flash? no need for vendor and other lenovo rom files?

Hello. Can I use split screen function and auto brightness? There are no buttons

Hello, maybe something seems to be moving for the J606F, it seems we can get a working unofficial twrp. Try taking a look at this https://github.com/adazem009/twrp_device_lenovo_TBJ606

Everything seems to work according to the dev, the only thing that doesn't work is the decryption. If you could fix the decryption and build an unofficial test rom it would be a great thing.

Sorry for the late reply. As you can see here https://github.com/adazem009/twrp_device_lenovo_TBJ606/tree/android-11.0/prebuilt the tree is using prebuilt kernel, nothing new. It's just the old lenovo built kernel binary being used, not the released OSS kernel source.

does clicking on the app icon from the app switcher not work for split screen?

So until lenovo releases an updated kernel version you can't do anything right?

Correct.
If there's a dev better than us who can develop on the mainline kernel, or patch the released source and makes various peripherals work it is still doable though.
for now just use gsi roms..

Hello, I'm using my tab (Lenovo TB-J607F) for serious working, mostly using projectors. I have a couple of questions:
1) Does your rom intergrate "PC mode" in Zui 13?
2) and is this rom working well for keyboard/mouse and projectors?
3) By the way, I checked many places in your website, github but I didn't see your list of features, what is features of your rom?
4) what about battery time? comparing with stock rom zui13 or zui 14?
5) Do we have "widevine L1" in your rom (for netlfix)?

Thank you.

The thing that's missing is the kernel module for the NT356(something)_HostDL or something in the kernel's {SRCROOT}/drivers/input/touchscreen/NT35something_HostDL.
The driver, IS available in a P11 LTe or something's kernel source available in lenovo downlooad page. (Sorry, my memory is very inaccurate, I was trying bunch of stuffs when I bought my P11 last year, it's a bit hazy now)
I made the driver located there, modded Makefile, got some kernel compile issue, and I somehow solved it, but the spi read only got value 00000000 and it didn't work. (You can get more info from postmarketOS-offtopic Matrix chatroom, chat history is logged in there, I got help from somebody a long time ago and there are conversations about this)
I got touchscreen to work with a prebuilt kernel (Lost the device tree) but that's it..
I hope we make something out of lenovo's junky kernel source codes.. The device has potentials!

Hi, I am also looking into the kernel source but don't understand why there are two touch displays that are active in the device tree. There is himax and novatek and both of their drivers seem to implement the same device driver for stylus support. Bit confused how there are two defined in the dts. Btw this is for the p11 plus edition. Any help would be appreciated

There are many revisions of the same model (in your case p11 plus), for example i'm unsure of p11 plus but for original p11 (j606f) the initial revisions shipped with the himax touchscreen while the later ones used nvt. And lenovo doesn't really know how to make their device trees proper to select the correct touchscreen's dt.

That makes sense. So I guess it probes both of them and selects the correct one? I guess that's against the device trees spec. Thank you though.
