FREQUENTLY ASKED QUESTIONS

(Please read them BEFORE posting anything in the thread!)
Q: Whenever I try flashing any lineage-17.1 build, I get the following error in TWRP: Updater process ended with ERROR: 7
A: This error appears whenever you try to flash an Q-based rom within a version of TWRP older than 3.4. Simply flash the linked below version 3.4 or higher, reboot back into recovery, and flash the rom zip again.

Q: Will any of the variants ever receive official builds from LineageOS?
A: In short, no. The reason is that, in order to get a modern version of Android working properly on an ageing device some legacy commits needed to have been re-introduced into the current source branch. These include a fix for something as fundamental as Wi-Fi.

Q: How often will new builds be released?
A: At least once per month: as soon as possible after each new Android security patch level is merged and whenever a new feature is added or a bug is fixed.

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 Installation
1. 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 tablet 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 tablet.

* 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.


Bugs
- The microphone is able to record sound, but the sound is very faint. This is due to Samsung's proprietary drivers, as determined by Skulldron.
- T710 & T715/Y: Camera viewfinder is misaligned with the dimentions of the display, such that the shutter button is almost off the screen
- You tell us!

Changelog
All major features and bug fixes are discussed in detail by the developers in the thread, whenever they are implemented. All builds include the latest upstream Changes for all devices from LineageOS.

715 working without problems

Hi, nice to have a dedicated new thread (after the slow dying of bonuzz's thread).
I installed the latest version on my SM-T715 and using it without any problems until now.
Using Magisk v18.
All my apps work after restoring them from Titanium Backup.
No problems with fingerprint (using left hand finger and right hand thumb).


Thanks for your support.

Anybody else also experiencing slower charging of the T810 than before? Mine needs several hours (3+) to be fully charged, before maybe 90 Minutes.
Or maybe its the battery, too old.

Yes, I actually felt the same, although I didn't measure the time and I have only charged once with this ROM.

Not a big deal though and everything else works great. Battery life seems improved too.

Thanks for your great work! Nice to see that the t815 will receive updates after LOS has dropped it.
Is it possible to provide check-sums for the download files? THX!

Had to switch back to Nougat.
Telephone didn't work - I could call but nobody could here me. People called me today but I didn't reveive it (nothing, no ring, no message).
And my usual VPN-Connection to my Fritz-Box didn't work.

Did you try Google's own dialer app? AOSP apps can be buggy with uncommonly used functions, such as calling on a tablet.

Somehow, in messenger lite, during videochat even if I see myself and the other party, the other party can't see me, just connecting video appears on the screen forever. T810 12.11 build.

Anybody with T815... How is idle drain? ROM works like an absolute champ but noticing strange idle drains while on airplane mode and everything off. Will check BBS overnight tonight to see if it sleeps at all.

    Hi ripee, I was trying to download the T810 ROMs but I got the error message that the download limit is reached. Can you increase the download limit or put the files to another place?
    This is a Google-imposed daily download limit, so ripee has no control over it. If you wait a day and try again, it will probably work.

    What I do instead of trying to download directly from anyone else's Google Drive: right-click on the file and choose "Make a copy". The copy will go into your own Google Drive with name "Copy of <original name>". You should be prompted to log in to your Google account if you're not already logged in via that browser. You can then download or let it sync from your own Google Drive.

    EDIT: I was wrong that Google would prompt you to sign in to Drive. You don't get a right-click context menu at all unless you're already logged in to Drive.
