FREQUENTLY ASKED QUESTIONSQ: Whenever I try flashing any lineage-17.1 build, I get the following error in TWRP: Updater process ended with ERROR: 7
(Please read them BEFORE posting anything in the thread!)
(Please read them BEFORE posting anything in the thread!)
A: This error appears whenever you try to flash an Oreo-based rom within a version of TWRP older than 3.3. Simply flash the linked below version 3.3 or higher, reboot back into recovery, and flash the rom zip again.
Q: I am seeing Error 7 when trying to flash a GApps package.
A: This is due to the system partition being too small to fit both the rom and the GApps package. You need to re-partition it with a tool such as the one created by Clamor (linked below). You will only need to do this once.
Q: When will any of the variants receive official builds from LineageOS?
A: There are no plans to submit these builds for official LineageOS support, but it should not matter. What is most important is that these unofficial builds be stable enough for daily usage, which they are, thanks to followmsi's tireless work in porting Android 10 to these venerable old tablets.
Note to Junior Members: It is frowned upon in the XDA community to ask for ETA's on builds, features, bug fixes, or other improvements to the code or its functionality.
Q: Even if neither dev nor flo will ever receive official LineageOS support, just out of curiosity, what are some of the differences be between unofficial and official builds?
A: The following technical changes are in effect:
- Built-in su root will be removed: You will have to download and install the su addon from LineageOS Extras.
- Tablet status > LineageOS updates will be activated, allowing for the OTA downloading of official builds.
- The official builds will be digitally signed by Lineage to prove that they do not contain malicious source code and are able to pass the Play Store's SafetyNet check.
Q: How often will new builds be released?
A: About once a week for both deb and flo, as soon as possible after each new Android security patch level is merged, and of course whenever a new feature is added or a bug is fixed, as per followmsi's advice.

Typically if you do not do a Clean Install then you are not allowed to report errors or problems. If you Dirty Install and you do have problems then you will be asked to Wipe All and Clean Install and see if the problems still exist. This is a DAILY changing rom and any bug that you found was not working on the previous day's build may be fixed with todays daily build. On a side note, the code implemented to fix that bug could potentially break something that worked on that previous build. So reporting problems on a day old build that you dirty flashed over whichever build of whichever rom you had flashed previously will not be accepted as a true error.
Problems known to happen after a Dirty Installation1. A muddled up mess of a system. You are taking a rom and installing a newer rom with changes over the top of your old rom. Between these two periods of time during which you used your phone and created data, changed system options, and used apps. This is absolutely increasing the risk of causing problems somewhere in the system/data partitions. Some people have luck with Dirty Flashing. However, it's always hit-and-miss because of what we mentioned above about bug fixes breaking previously working functions. Dirty flashing doesn't only create problems if the source code of the system data and the system settings of the new build are significantly different from those of your previous build. That's not to say that Clean Installing won't ever create problems, but only bugs present on a Cleanly Installed rom are relevant for development purposes.
* Clean Install: Fully wiping everything and installing the rom onto a fully clean system/data partition of the phone.
* Dirty Install: Installing the rom and GApps over top of the older rom to save time and not have to reinstall all the user apps and tweaking system and app settings that usually take a lot of time to set up as you like.
