Hi dear forum members. I'm going to introduce you in this post that GM 9 Pro ( codename = GM9PRO_sprout ) device sources.
We have 2 sources to build rom. Those:
* Device tree
* Kernel tree (Thx to GM)
* Vendor tree
We have three branch.
First of them "pie" branch. You can build Pie (Android 9) custom rom(s) with it.
Second of them "ten" branch. You can build Q (Android 10) custom rom(s) using it.
Third one "eleven" branch. You can build Android 11 (R) custom rom(s) using it.
Don't use boot.img which is located in out folder. If you use it is your problem.
We wrote a script to patch rom source automatically. It's executing script after ". build/envsetup.sh" automatically. Make sure that it finished successfully. You should see that "You're ready to building". Otherwise you should to patch rom source manually.
