I like GNU/Linux and FOSS. Most of what is here is mainline Linux on phones: getting current kernels to boot and drive the hardware on devices that shipped with Android.
Google Pixel 4a (sunfish, Qualcomm SM7150)
- mobian-pixel4a-port: Debian 13 with Plasma Mobile on a mainline kernel. Recipe, device fixes and install guide.
- linux: the kernel tree.
sunfish-venus-v7.2is the default branch, newer work is onrelease/sunfish-0.26.0910.20. - pmaports-sunfish: postmarketOS packaging for the same phone.
- pixel4a-stmfts5-mainline: touchscreen patches and a userspace firmware flasher.
- stnfc: userspace NFC toolkit for the phone's ST21NFC chip.
Samsung Galaxy A52 4G (a52q, Qualcomm SM7125)
- a52q-linux: bring-up notebook and tooling for mainline Linux and U-Boot.
- a525f-edl-unbrick: unbricking the phone over EDL, with a working firehose write path.
- pcad: draw and render ProfiCAD-compatible schematics from JSON in pure Python.
- tcs2-p102-eink: ESP32-S3 driver for the MpicoSys TCS2-P102 10.2" e-ink display controller.
- bazos-AI: an agent that searches and filters bazos listings from a prompt.
