LineageOS is a free, community built, aftermarket firmware distribution of Android 12 (S), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

It's amazing to see such an old device get the latest Android version. Thank you so much for keeping the device alive! I will try the ROM tommorow.

Surnia with Android 12... I dont believe it ! OMG...
Any plans to become official?

---

Unlocked a bootloader for the first time and installed 19.0 to my XT1527 (US) with stock Lollipop 5.1 which had been upgraded from 5.02 OTA. Wasn't able to use ADB to sideload with the 19.0 recovery but the 17.1 recovery was able to sideload this 19.0 ROM.
As part of the 3g shutdown, US carriers are restricting LTE access to VoLTE-capable phones. I was curious to see if my XT1527 could survive these restrictions with a fresh VoLTE-capable OS. AT&T has a whitelist and surnia didn't make the cut. Not sure how AT&T determines if a phone is VoLTE-capable but it might not permit XT1527 access regardless of the OS or VoLTE capabilities.
Quick answer: Not yet and perhaps not ever. Since early March 2022, I've not been able to access LTE on Stock Android 5.1, official Lineage 17.1 or unofficial 19.0. I have 2g/3g only without MMS. But other Lineage features work as advertised. It's pretty fast without Gapps. Both the unofficial 17.1 and the unofficial 19.0 builds are impressive development efforts.
There is no stock Marshmallow 6.0 for the US XT 1527 and the upgrade from 5.02 to 5.1 disabled band 12 from US phones. Evidently, Moto didn't want the hassle of certifying the XT 1527 for VoLTE and instead chose to disable band 12 at the request of one major carrier that wanted to use 12 for VoLTE traffic. I'm wondering if that could cause LTE-access problems when flashing 19.0 on top of 5.1. The official 17.0 instructions were clear that we should start with stock Marshmallow but I wasn't sure about trying non-US ROMs.
Perhaps reinstalling Lineage 17.1 starting with a non-US 6.0 (or US 5.02) stock ROM would restore LTE. Another possibility is to switch within my MVNO to a T-mobile SIM (another major US carrier.) Anyone know if any US carrier will permit surnia access to LTE on any OS after the 3g shutdown is complete?
Also wondering if VoLTE is implemented in a proprietary way by US carriers that hinders open source OS development work.
Thanks again for a nice effort. The XT1527 is the only smartphone I've ever used...will hate to give it up if/when both LTE and 3g access are removed.

I have tried this rom today and most stuff works fine. i have encountered one issue with the "3 button" controls setting turned on, the trebuchet launcher crashes if you try to see all the open apps. This doesn't occur if i use the " nova launcher". Keep up the good work.

The "laggy UI" seemed to get worse over time in the week or so that I tried the first cut at 19.0 for Moto E 2015. Even though I didn't load extra software, by the end of the week it struggled to bring up a PIN-number screen unlock without displaying it on the Lineage logo simultaneously. I don't remember it doing that after 19.0 was first installed. Perhaps freeing up memory or other resources when unneeded would improve UI performance.

Not just US carriers. As far as I know, there does not exist any fully open-source VoLTE implementation on any phone, for any carrier, anywhere in the world.

My phone has a low battery
I think I need to change it or maybe I should buy a used E2.
What do you recommend?
I hope it will be supported for years to come. I don't want to leave it. For a basic use, it is the top. It is comfortable in the hands. I am lost with recent smartphones. Too big for my taste.
We need more E2
Thanks for the support!

There are new E2 batteries available on both eBay and Amazon for around $6, and that typically includes a small toolkit for the job. Here is a listing for a brand name FT-40 battery for the E2 for $5.42 w/free shipping.

For sure, but I need an hot air gun to detach the screen before replacing the battery. I don't know if I can do without it.

The only tools I used were thin plastic edging tools (resemble guitar picks), a pry tool, and a T4 Torx security screwdriver. When reassembling, some 3M adhesive strips work nicely for getting the display back nice and snug. A regular hair dryer can, of course, be used to warm the edges of the display first, in order to loosen the underlying adhesive and make prying.a bit easier. On the three Moto E 2nd Gens to which I've done repairs, I haven't needed to resort to heating the screen first.

Also, I should mention that when you are able to run the plastic edging tool all the way around the screen -- essentially breaking the seal -- use a playing card to assist you in prying the display from the phone body. The E2, as you probably know, has a LCD + touch screen digitizer display assembly. A playing card helps greatly with getting under the digitizer versus the edge of the LCD, which can be ripped from the digitizer if you're not careful.
OP, I do apologize for posting off topic in your thread.

I'm currently running LineageOS 17.1 with A10 and doing great. I would like to try 19.1 with A12. But I have a doubt because the opengapps.org site only shows gaspps up to A11 and this ROM is A12. Could you help me and tell me if they exist and where I can download the gapps for A12

I have some tools but they are very cheap, including a torx and a plastic triangle, so pretty useless. I think I can use an old phone card. Let's say that the most difficult task is to detach the screen, then I hope to be able to remove it with the tools I have. I have to buy 3M double-sided tape or glue. as well. I will keep you informed as soon as I have the spare parts.
Thank you for your suggestion

No problem. Yeah once you get the screen detached from the midframe, the T4 Torx will remove all screws holding the logic board in place, allowing you to then access the battery Take care when detaching.the display not to rip the flex cable connecting the display to the board. Pry tools won't get anywhere near it, but when prying it loose use caution .

I put ROM 19.1 to test and had to restore the save again and continue with the official version 17.1. This 19.1 everything worked for me but when I open the PHONE application, MESSAGES and CONTACTS close automatically. Turn back because without these applications it is impossible to have a mobile.

Is unlocking the bootloader always to be done? I have lollypop in this other phone, not Marshmallow.
