Codename shared with another phone. X1 is also the codename of the Go Mobile X1. Codenames are only unique per manufacturer, so before flashing, check that a build names the ADVAN X1, not just X1.
Newest ROM build 2 weeks ago (1 ROM still current). A phone that still gets updates keeps going long after its manufacturer stops.

Before you flash
Flashing generally means unlocking the bootloader, booting a custom recovery, wiping, then installing the ROM. Exact steps differ per device and ROM, so follow the Install guide for the one you pick, and back up first. Check what can break (banking apps, DRM, carrier features) and how to get back to stock before you start. Why flash a custom ROM · All guides

Dates show when CustomDroid first indexed each ROM for this device, not when support originally launched.
ROM availability and links come from each project. CustomDroid indexes builds, it doesn't mirror them — always download from the official project, verify the file's hash/signature, confirm it matches your exact codename, and back up before flashing.
