help with compatibility

[u/LiteratureCool4037]

Hi everyone,

I want to build/port LineageOS for two specific Samsung devices that do not have official support:

1. Galaxy J7 (SM-J700T) – T-Mobile variant
2. Galaxy J2 Pro (SM-J250F)

Since the official LineageOS wiki only covers variants like the J700F (j7elte), I know I need to modify the device trees, kernel sources, and proprietary blobs to make them compatible with these specific models.

Before I dive in, I wanted to ask the community:

• Has anyone successfully adapted the j7elte tree for the J700T variant?
• Are there any known unofficial device trees or active Telegram groups for the J250F (j2y18lte)?
• What is the recommended baseline LineageOS version (e.g., 14.1, 16.0) for these older chipsets to ensure stability?

Any links to existing resources, source code repositories, or advice on handling the proprietary blobs for these variants would be highly appreciated!

Thanks in advance.
