FREQUENTLY ASKED QUESTIONS

(Please read them BEFORE posting anything in the thread!)​

Q: The room is bootlooping the first time I attempt to boot into it after clean flashing. What should I do?[/COLOR]

A: Force reboot using the Power and Volume Down buttons. The rom will boot properly the second time around. This is a known bug and it affects clean flashes only.

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: No.

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 rom bootloops only after clean flashing. Force rebooting allows it to boot properly the second time and every time afterwards. See the FAQ's above.

- The cameras work, but with a delayed response, so they are impractical to use.

- T719 & T819: RIL does not work at all.

- You tell us!
