Have to take into account this is more a carrier issue than googles, the issue is you not buying the phone from them but from Google and they are not going to go out of their way to support a phone that was not purchased from them
[Google Pixel 6 Pro] ibrahim52:
Thank you. You should also be posting same on pixel 6 forums to get more attention.
[Google Pixel 6 Pro] reas0n:
Google doesn't even sell P6 in Poland. Also as I said in description: hardware supports it, my carrier uses same band/frequency as other carrier in Austria which is supported. If you still don't believe: take a look on Pixel 5 forums, they have a 5G unlock with Qualcomm tools. 100% it's Google's stupidity.

In the past I bought some Chinese phones and with global ROM they just worked..
[Google Pixel 6 Pro] maxius4:
The issue is the carrier and Google can not sell a phone with everything unlocked as it would run across a world of hurt from every country's on earth regulators that deal with spectrum use. Sure you can "unlock" it but with age of a phone comes vulnerabilities and fw updates to fix issues also your carrier / someone may care more than you want them to about you essentially breaking your country's communications/spectrum laws. Honestly, is it really worth all the trouble to make it work how you want it to or get a phone from your carrier with the support you want?

I tried flashing this ROM and in Lineage Recovery it said something about an OTA downgrade and I couldn't figure out the reason so if anyone could help me I'd be very grateful :)
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.arkajyotibir:
I've tested this out and the bugs, bug me too much (lol 🤣).

The things I found annoying ( besides the regular AOSP problems which are standard)

No quick tile for sound. It was annoying to have to press the volume key and change to vibrate or silent.

No option for pocket mode. The phone often went on and did some random stuff or registered fingerprints.

Battery life was awful and had frequent kernel panics.

Random restart sand freezing was the new normal.

Currently, I'm on the 4.9 update and feel it's very stable without any need to upgrade to Android 13 now. I use it as my daily driver because I really need the Google photos storage, and other pixel goodies.

The best thing about this ROM would be getting VOLTE, but alas it's something we can't have ( yet 🥹)

Thanks a lot to the developers for this beautiful ROM, and hope that we can get VOLTE soon.

I forgot that I even commented on here (first time posting on XDA 😅).

So just wanted to say that it was my fault (obviously). I flashed the wrong recovery image. Anyways, I've been using the ROM for a day and I've explored some stuff but I am experiencing some bugs and stuff but I guess that's normal lol.

Which camera app are you using? may you share the apk.

Hello @dr.arkajyotibir

Many thanks for the prompt response, I really appreciate.

I'll install the same Gcam after flashing the Rom, I'll start with version 4.9.

Kindlly allow me to ask more especially on applying the config file after installing the camera.

Hello,

Do we need to rooted in One UI to be able to flash this Rom?

Regards,
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Geofrey Kazaula:
It is taking long on G boot screen,

I can from One UI 4.1 without root.

I just unlocked bootloader then flashed recovery, from recovery I flashed the Rom and reboot.

It is now after booting on G logo seeming to load but taking long.

Is this normal or a step missed out?

No You don't need to root the device. However when changing the mixer_gains.xml file ( to get back better sound ) you need root
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.arkajyotibir:
I normally unlock bootloder

Send the recovery via heimdall

Format/Factory reset and Format System

Apply the rom from SD card

After boot, install magisk and root, then install root explorer and buildprop editor

Change the mixer_gains.xml.

Reboot, completely remove magisk and root

Do a factory reset ( I have OCD, lol )

This gives me better and stable operation ( well, atleast i feel so lol )
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Geofrey Kazaula:

Hello @dr.arkajyotibir

Just one clarification: "Do a factory reset ( I have OCD, lol )" is the factory reset necessary for the effect to apply? I had already set the phone now thinking that I have to repeat again.

Hello, I am a Chinese user and I really like this ROM. I have been using it until now, but it does not support a Chinese operator. The latest Chinese version of Samsung firmware supports it, so I was wondering if you could add product.img from the CSC in the latest Chinese version of Samsung firmware to the ROM. Or could you create a separate card brush package to make it support it? If possible, thank you very much.

I'm trying to flash Jockeys 1.24 hardSPL and everytime I attempt it, I get put into the recover from flash routine - ERROR[262]: UPDATE ERROR. Luckily all the times so far its just been a case of battery out and restart and everythings fine.

I'm slowly porting my Tizen OS apps to Wear OS while also adding new features. These apps display information like speed, pace, heart rate, and altitude while keeping the device awake. They all have features that minimize power consumption and prevent screen burn-in. The posts to follow will contain app descriptions and screenshots.

First up is Always-On Speed, which is essentially the Wear OS version of the Tizen app Always-On Speed Pro.

Please message me here or by email if you would like to become a beta tester or volunteer as a translator.

Always-On Speed v7.0.0 is out and brings an exciting and very useful new feature:

• Major new feature: text-to-speech/voice support. The app can now read the speed (when exceeding the speed limit set by the user) and time (when the screen is touched) aloud! This feature does not noticeably increase the power consumption and is available in all common languages.

• Automatic rain detection. Text-to-speech for time is disabled when rain drops are detected on the screen.

• "Press again to exit" is back.

Dear author @parshakov

I have an idea for you: so far, WearOS has not created a simple application showing the map (e.g. OpenStreetMap) in off-line mode, which we load ourselves into the watch's memory and additionally with the GPS track navigation function (from a .GPX file) ("Courses" function from Garmin) . There is no such thing on the market and it seems to me that with a well-developed application such something could be sold for 5 $ very well.

P.S. Do you want to be rich? This is the moment!;)
