Marathon OS 1.0 for the Zinwa Q25 (new install)

Marathon OS 1.0 for the Zinwa Q25: images for a new install.

This replaces Android and erases everything in userdata (apps, data, internal storage). Updates after this arrive over the air from stable/zinwa-q25_marathon_edge.

Files:

• q25-duranium-20261105-e43659a6.userdata.img.zst: the whole userdata partition (ESP, kernel, initramfs, device tree and the root)
• u-boot-q25.bin and gimme-uboot.py: U-Boot, put into the phone's own lk image by gimme-uboot.py
• q25-duranium-20261105-e43659a6.SHA256SUMS: checksums for all of them; check them before flashing

Install steps: https://github.com/patrickjquinn/Marathon-Shell/blob/release/q25-v1/docs/install/ZINWA_Q25.md

Known limitations:

• Battery: standby is about 10 hours. The CPUs do not use their idle states yet; that comes in the next update. Suspend with the screen off follows only once calls, SMS, notifications and media playback are proven to work through it.
• Satellite positioning is new and not yet tested outdoors.
• Calls, SMS and Bluetooth hands-free are in this release but were not retested on it.
