Sources are usually in the XDA link

[pmosgtexswifi]

I mean, can you share the source code of the project?
also which kernel did you use?

[ronnz98]

Its in the XDA link as said:

Source :

• LineageOS
• android_kernel_samsung_gtexswifi
• android_device_samsung_gtexswifi
• proprietary_vendor_samsung_gtexswifi
• android_hardware_sprd

[pmosgtexswifi]

I want to compile it myself, can you please upload the e/ROM project to github?
(there is no /e/ ROM gtexswifi source in the links) see

also i cant swipe lock screen and camera on lock screen -touch screen works- (There was no such situation in lineageos)

[ronnz98]

As said I took the sources as above and used it only internally for my build. I use github only for one device yet and there will be not much more in the future since I’m not a developer.
You need to download the device, kernel, vendor and hardware files and put in your build environment. Then you can build with docker or the repo way.

Hi @pmosgtexswifi, welcome to this Forum.

Building Android (i did it for the Galaxy s4mini) is not as simple as building Postmatket OS, (i did it for the Galaxy Tab 2) you will need a more powerfull machine (mininum 16GB of RAM)

i have tested and documented the 6 ways to build PostmarketOS for a Samsung device, and i am proud to have found a smart way to easily switch between AndroidOS and PostmarketOS (if you build postmarket to work from the SDcard)

Porting Postmarket for a new device is a very big effort (compared to my IT skills) that i tried a few years ago for the Galaxy s4mini, and was not abble to achieve, (the Galaxy Tab 2 was already ported by another guy, and it is now a community supported device…)

Installation guide & if didn’t boot

[freechelmi]

Hi , I have a volunteer with T280 willing to test any build

Do you think there is something that would keep this device from running Android 13 ? DO we need the LOS-UL branch maybe ?

[ronnz98]

The latest sources are for Android 7! First you need to find a developer who works on a newer Android version- I think that the chance for higher versions than Android 7 is very low

Hello, I installed this firmware and it works fine, but there are 2 bugs, Bluetooth and unlocking with a swipe up, is there a chance that this can be fixed?
