Pls check ro.boot.wificountrycode on your both Pixel C devices ..

getprop ro.boot.wificountrycode

Same countrycode on both devices ?

If yes, we need to check related changes on 19.1 .. as wifi kernel drivers remain unchanged in 18.1 and 19.1.

I've checked both devices.
Stange thing is: Display in the settings says `Europe` and getprop says `GB` on both devices.

Hey there, it's been a while for me on these forums !
Mainly because as it's difficult as hell to get any replacement screens for the Pixel C, I just bought another one that wasn't too far from me... (a 64GB btw, so quite cool to see that, along with a proper magnetic keyboard that is a pleasure to type on, and quite sturdy, not really mushy)
Someone here sent me a link to get screens and such, but it's really difficult to even understand how to place an order.


----

So now that I'm back with using a C, I can say that it's not aging well, last time I used one was on the Android 10 days and it was really smooth...
I think that instead of bumping Android versions and following ROM development, we should focus more on bugfixes and optimizations...
That tablet has potential SoC wise, and the 3GB of RAM should only be an issue for demanding stuff...
That ROM should include zRAM or something, and a bit more aggressive LMK to help smoothen everything out.
Too bad the NAND flash is quite slow otherwise it would have helped using it I think honestly.
Android 12(L) may be the last proper version we'll get because of the really ancient kernel we're using.

3.18 isn't of good use, and NVIDIA being who they are won't help us... unless that opensourcing of drivers also extends to embedded devices like everything in the Tegra family and such...

 

[mrbubba999]

Are there any further updates planned for this?
I'm not sure what tablet I could replace this with

 

[alterjsive]

The LineageOS 19.1 2022-05-07 is a great rom, thanks so much! Any idea why the battery usage is so high?

Pls install Magisk 24.1 and test to set wifi-country code again.

Magisk is using "resetprop" to overwrite country code.
While regular "setprop" may has some read-only prop issues.

Needs to be checked ..

Could you please elaborate more on how to use magisk to set wifi-country code?
As I am new to this and I think I have the same problem.
Thanks!

Hi.

Can be a bit complicated.

Magisk - [github.io] - resetprop
Magisk - [github.io] - Resetprop

You can change the prop values while booted.

Spoiler: Example

dragon:/ # getprop ro.boot.wificountrycode
US
dragon:/ # resetprop ro.boot.wificountrycode GB
dragon:/ # getprop ro.boot.wificountrycode
GB
dragon:/ # resetprop ro.boot.wificountrycode TW
dragon:/ # getprop ro.boot.wificountrycode
TW
dragon:/ #

That would only be temporary since the default value will be restored on (re)boot.

Might work for testing, not sure if it needs to be set earlier (during boot) to make a difference.

You will need to use a boot script to adjust the prop value on boot.
Magisk - [github.io] - Shell scripts
Magisk - [github.io] - Boot Scripts

You can use the MagiskHide Props Config module to change the prop instead.

Quick search, I did not find an official list of country codes.
This is one of the better lists I found.
AppTweak - [apptweak.io] - Country and language codes


Cheers.

Hi!
I have been testing Lineage OS 18.1 on my old device for one month. It runs quite well overall

I have noticed that turning on WiFi and Bluetooth at the same time pose a problem though, making it virtually impossible to stream Spotify on a speaker. Has anyone encountered the same issue?

Hi!
Do some of you have the same problem? The audio stutters a lot via BT.

Help! Flashing custom rom and then it crashed midway. Lost TWRP and when I tried to use adb fastboot, adb unable to recognize device. Unable to find Pixel C adb driver and using other drivers doesn't seem to work. Any ideas?

I flashed los 19.1 and pico Gapps using Bugjaeger app from playstore on my OnePlus Nord 2. Works well. No need of pc to unlock bootloader and flash TWRP and rom and Gapps. Used this because my old PC didn't recognize pixel c in bootloader modus. Made connection between OnePlus and pixel c through USB c to c cable.

Never mind! I managed to solve this. My pixel C has come back to life stronger than ever!

Hi All, can anyone connect the physical keyboard? My pixel c can't find the keyboard in this rom. Not sure if it's my own issue only.
Thanks.

Yes.

Just upgraded to Magisk v25.0.
Everything seems to be fine.

Question - is there a way to completely disable the 12L dock thingy? I find it useless for my purposes... And somewhat ugly

Need to check the country code script on 12 .. maybe the process of applying the country code has been changed.

Every kind of help/input is welcome.

Michi has started to use some Nvidia/Tegra components .. maybe you can adjust the dragon sources to be able switch to Nvidia sources.

Pls push your changes to Github.

I don't have the time anymore to work on Android like I did in the previous years.

Yes .. Magisk 25.0 works well .. and Zygisk works on "older" kernels now.

You can disable "Taskbar" in lineage settings to get rid of the 12L taskbar .. no idea if Lineage is planning more changes related to the "12L style" on tablets.

Changes:
- Google security updates -> June 2022
- Patched system/netd to bring back Network traffic monitoring on older kernels.
- Patched frameworks/base & Permissions to support microG
- Latest LineageOS changes

As SDK level increased to version 32 we have to use new gapps for Android 12L.
Pls check latest gapps builds here ..

How do I get rid of the grey bar with the list of apps at the bottom of the screen? It used to swipe away, now it's there permanently

Settings -> System -> Buttons -> Enable taskbar -> switch off!
