• Why?
  • Manufacturers like Samsung stop releasing OS updates for their devices long before the hardware becomes truly obsolete. These updates are important for system security and sometimes come with other nice improvements. Volunteers at the LineageOS organization have rescued many such abandoned devices by releasing their own distribution of android to run on them and supplying precompiled builds of their own. But, even they have their limits with supporting old hardware. Official LineageOS builds are no longer available for some of my devices, so I've compiled my own and shared them here in case others find them useful. They come without warranty and you use them at your own risk, but if you have backups and generally know what you're doing (i.e. are familiar with the basics of tools like Odin, adb, and TWRP) you'll probably be okay.
• How do I use these builds?
  • Follow an installation guide like one of these: chagallwifi | chagalllte | klimtlte | klimtwifi.
  • If that's not sufficient, take a look at some of the threads on the XDA forums.
  • If all that seems too complicated, either keep reading until you understand, or congratulate yourself on recognizing that your true calling lies elsewhere and then enjoy your life far from such noise.
• Can you help me with X?
  • No, sorry. This is a volunteer effort and I have to set boundaries somewhere. But the XDA forums are an amazing (if labyrinthine) resource, and you may find general guidance on running non-stock firmware within.
  • If one of my builds is utterly broken, though, I would like to know. You can message me on XDA or send an email to .
• How were these created?
  • Using the steps outlined in the LineageOS build docs, with added device support from the exynos5420 projects, mostly automated with some custom scripts. Everything is compiled in a clean Docker container.
  • If you'd like to try building some yourself, you may have luck with this docker-lineageos project. I haven't personally tried it, but it seems similar to what I've made for myself.
• What special tweaks/patches do these builds contain?
  • None, at the moment, aside from tweaking the OTA updater to check this site for new builds. I'm fairly new to this, all things considered.
  • There are other builds for tablets from the same exynos5420 family with more customizations from other contributors on the XDA forums. I've linked some below. Mine are comparatively vanilla.

• Future plans, as time and energy allow:
  • Eliminate annoying notifications by switching to signed builds
  • Ditto for enforcing SELinux policy.
