Building Experimental Version

Hi,
since I like to stay at Marshmallow for now (especially because of the lack of Xposed for Nougat) but also like to already make the switch to Lineage, I see no other way then building Lineage based on CM 13.0 for my both devices (Oneplus 3 and kenzo) by myself.
While I'm familiar with building CM, it's not clear to me if it's possible to make a "Experimental" build (for dirty flash migration) and if so, how? Are there any build flags to be set? Any additional steps after building? How are the offical "EXPERIMEMTAL" builds done at download.lineageos.org?
Thank you very much in advance, it's very good to see Lineage OS getting traction after the Cyanogenmod shutdown.

Same problem

I would also be interested in this. Thank you for all your help.

No solution found?

I'm not sure if you all know this exactly but, the LineageOS Experimental builds is actually CyanogenMod Migration Builds.
It's intent is for those who use CyanogenMod installed and don't want to just wipe the whole device clean so the Experimental build is to install over the current CyanogenMod without wiping anything to Migrate from the CyanogenMod to the LineageOS. Then when it's done, you install the LineageOS Nightly build (or Snapshot if it's available) over the Experimental without wiping anything to complete the Migration.
With that stated, it would be a real challenging endeavor to create an Experimental build with that type of Migration feature.
I would applaud anyone, outside of the LineageOS Devs, who can accomplish this.
But, I'm not one to gossip... So you ain't heard that from me... LMAO!!!

If you take a look at the Console Output of Jenkins, then there are build-scripts... I think they can build migration builds/they "know" how toll build these...
Fetching changes from the remote Git repository > git config remote.origin.url ssh://[email protected]/lineageos/build_scripts # timeout=10
Do you now how to get these script(s)?

To observations:
- In https://forum.xda-developers.com/showpost.php?p=70944088&postcount=26 and https://forum.xda-developers.com/showpost.php?p=70959718&postcount=27 it is described how to compile the current version of the cm-13.0 branch of lineageos for the Moto G (osprey). This build can be flashed on top of a Cyanogenmod 13.0 build without any problems. After reflashing Xposed it is also working.
- These are the changes between a "normal" and and "experimental" build of cm-13.0 on Jenkins for a certain phone (manta) on Jenkins:
builds: https://jenkins.lineageos.org/job/android/617/parameters/ and https://jenkins.lineageos.org/job/android/618/parameters/
changes on gerrit: https://review.lineageos.org/#/c/160268/ https://review.lineageos.org/#/c/160269/ https://review.lineageos.org/#/c/160272/
I totally unsure, what these patches really do, but I would guess its about checking signatures during the process of an OTA update.

160269 only adds the watermark... I think 160272 does the "real" migration, but I don't know, what the other change does...
I'll try to flash a normal nightly, but if it works, why do they make data migration builds?
But if I would build a migration build I only had to apply the changes to my repo and that's it?
EDIT: I just installed LineageOS over my CynaogenMod installation (14.1) on my HTC One A9 and it worked

The watermarks are there for a reason.
Once the migration has completed, and your on the main screen with the watermarks, it is an indication that you have migrated successfully and ready for you to flash the latest Nightly build (or Snapshot build if one has been released).
Reboot back to recovery, and without wiping a thing, you'll then flash the Nightly and GApps. Wipe Dalvik and then reboot.

No Experimental Build for Motorola X Play (lux)

Hello everybody,
why is no experimental build for Moto X Play present? I want to upgrade my cyanogenmod 13. to LineageOs 14.1. Is it possible to upgrade without the exmperimental build (and without loosing data)?
Regards,
Guido

Experimental builds are released based on the device's needs for the upgrade compatibility.
If the Lineage team decides that a device doesn't require an Experimental Migration, then they are confident that the clean flash of the Nightly won't result in anything negative.
They only concentrate on the device ROM's and not the saving of the apps and such.
The Experimental Migration builds being able to Migrate apps is just a bonus feature. With that stated, not all apps are compatible and may need to be removed after a Migration has been accomplished.
It's hard to explain via text so I hope that I explained it okay.
Peace and Love!

Lineage OS updater missing in settings

I have the latest Lineage OS Rom (Feb 22,2017) on my MI Max Hydrogen and noticed that the Lineage update option is now missing within settings > about phone. Not sure if it was taken out in the last build or what happened to it.
I did flash a new gasps package last night for Google assistant however, no other changes. I'll do a new install if I have to, just thinking someone might have some insight beforehand.

What to flash in case of update Lineage OS?

Hello,
I am currently running a nighly build of Lineage OS 14.1 on my LG G2.
I was wondering:
- when a new 14.1 nighly comes out: Do I have to flash the Gapps and root zip also after (dirty) flashing the new nightly?
- and what in case of a 14.2 build or even a 15 build? Do I have to do a clean install in that case?
Thank you in advance!

Don't know about 14.2 or 15 because they are still no where.
But for new 14.1 no need to flash g apps and root zip again.

It doesn't hurt to flash an updated GApps package along with the Nightly update.
If you have SuperSU, then you should flash it again along with the Nightly update. This is because updating the Nightly also affects the SuperSU modifications and binaries. Re-flashing the SuperSU will reinstate the SuperSU modifications and binary installation.
If you don't re-flash SuperSU, then you'll get a notification from the SuperSU app that the binaries need to be installed.
So the GApps is up to you and the SuperSU is a yes.
I wish you the best of luck!
Peace and Love!

To add on to what @Ibuprophen said...
Historically speaking, dirty flashes are usually fine within the same major version number, while clean flashes are often required when the major version number changes.
The ROM maintainer will provide instructions for any exception to this general rule.

Thank you for your replies!
Is 14.1 --> 14.2 a major version number jhedfors? I mean: when there is 14.2, can I flash it dirty?
I flashed my phone yesterday, and I got a lot of errors. After flashing Gapps and the root-zip from Lineage, it was all solved. So in my case I have to flash them all again everty time.

Current versioning is as follows: Major.Minor.Patch
That would be considered a minor change. But as I mentioned, it all depends on the advice from the maintainer.
You should not need to flash either Gapps or official Lineage superuser after nightly update. You might want to post logs of you have any issues next nightly update.

Experimental Builds

Hi I am currently a cm user on cm13 and I wanted to wait a couple of months before switching to lineageos does anyone still have to experimental build for the M8? I don't want to lose my data.

I do have the "lineage-14.1-20170125-experimental-m8-signed.zip".
Though, i don't, personally, have the device, I had grabbed it for another member who had asked for a copy a while ago, the member ended up not wanting it anymore so I never uploaded it to my File Host Account.
I saw your question and your in luck! I still have it and will upload it and provide you a link to download it. Just give me a little time since the File Host site is running a bit slow.
Just an FYI... The Experimental builds are called Experimental Migration builds for (as you probably already know) the migration from the CyanogenMod to LineageOS.
In the meantime, here's a link that should be helpful in referring to that outlines the process in using the Experimental Migration builds.
Official LineageOS - Update & Build Prep
The following are some more helpful information regarding your device.
Official LineageOS - Info about M8
Official LineageOS - Install LineageOS on M8
I'll post the link as soon as the experimental build is done uploading.

Noooo..... I'm stuck in the Nexus with Kirk and Picard!!!

Well here's the link to the experimental build
lineage-14.1-20170130-experimental-m8-signed
Some individuals ask this question but, the MD5 file is only the checksum file that TWRP can use to verify the zip file. If you want to use it, just place it in the same location where the zip file is.
Be sure to read the information on the following link.
Official LineageOS - Update & Build Prep
This way you will understand that, after the migration has completed, you need to reboot back into Recovery to flash the latest nightly build.
*** PLEASE NOTE: If you use SuperSU and GApps, be sure to flash in the following order (at the same time).
1) Experimental build
2) SuperSU
3) GApps (for Nougat)
Then after the Experimental migration has completed, and your ready to flash the latest nightly (which is required to complete the migration), be sure to flash them in the following order.
1) Nightly build
2) SuperSU
3) GApps (for Nougat)
I know that it's redundant but, the LineageOS will undo the SuperSU and conflict with the GApps. This is why it's important to flash in the order above.
FINALLY... A hint... The way to know that the first Experimental migration has completed is basically after the device is booted and your done with the initial setup. Simply... If you are staring at the Home Screen... Then it's ready for the Nightly build to be flashed in the above order.
I did my best to explain this via text.
Please let me know how it went!
I wish you the best of luck!
