[ROM][UNOFFICIAL][10] LineageOS 17.1 [T713][T719][T813][T819]
- Thread starter ripee
- Start date
Hi all,
Is anyone using this ROM on a T813 and not having WiFi Issues?
I don't think I'm alone as there seem to be quite a few post about it, but I'm struggling to find a fix (also happens on Lineagos 16.x as well).
Basically, the WiFi connects without issues to both 2.4 and 5ghz networks, but the connection isn't stable in that it will work at full bandwidth for maybe 1 minute, then completely stall for 15 -30 seconds that start working at full bandwidth again.
If I tether the table to my phone's hotspot (oneplus 6t), it's rock steady and there are no pauses/disconnects at all.
I've tried using 4 different routers (varying in age, going back about 5/6 years old), but I'm getting the same behaviour.
This doesn't happen on the latest version of the stock Samsung firmware, I flashed it and ran it for a few days without any issues.
I've also tried flashing the latest official modem files on top of Lineagos 17.1 and get the same result.
Does anyone else have this or have any ideas on how to troubleshoot further?
Thanks
Macca

On my 713 I have to use the wifi auto reconnect app to stay connected.
Can you let me have the link of the exact app you are using - There are a lot of Wifi Connection apps it would appear and it would be good to know which one is working for you.
Cheers

It is the one by stickyapple com. Look for the yellow circle with the wifi symbol inside it.
Is there an issue with the unofficial builds? It seems that the last build dates back to three weeks ago.
Looks like it miss the 17.1 branch:
buildbot.wickenberg.nu
Branches found:
cm-14.1
lineage-15.1
lineage-16.0
Problem is maybe here:
If upstream delete, downstream don't know what to do, lol

Not much wickenberg.nu can do, the entire msm8976-common account is gone, only hope is if dev links the manifest again on new account, and the wickenberg fix the link to it, else not.
Best save last build ^_^
This is unfortunate - the choice may be to revert to 16 or go without security updates...
The only choice is try build 18.1 by self, or hoping someone in near future will emerge.This is unfortunate - the choice may be to revert to 16 or go without security updates...
As for now I agree with you, very unfortunate, but we all change.
Building it myself is beyond me... but I'd be happy to Alpha/Beta test if someone wants to give it a try!The only choice is try build 18.1 by self, or hoping someone in near future will emerge.

No choice, the 16.0 builds are disabled at wickenberg.nuThis is unfortunate - the choice may be to revert to 16 or go without security updates...
It is a very unfortunate state of affairs, particularly as I have just put in a new battery and installed Adaway and the app tracker blocker from duckduckgo! The tablet is now faster and smoother than it has ever been. I hope somebody with more skills than I have picks up the ball on this one and continues development. I know I would contribute to the cause!
Does anybody else have problems with the link to SM-T719: gts28velte within the top post?
For some reason the T719 is not available anymore?
Does somebody have still a backup of the latest rom version? This should be:
lineage-17.1-20211120-UNOFFICIAL-gts28velte.zip

If it's not here, no luck.

LineageOS is a free, community built, aftermarket firmware distribution of Android, which is designed to increase performance and reliability over stock Android for your device. All the source code for LineageOS is available in the LineageOS Github repo. If you would like to contribute to LineageOS, please visit our Gerrit Code Review.
Code:* [B][U]Your warranty is now void.[/U][/B] I am not responsible for bricked devices, dead SD cards, * thermonuclear war, or your getting fired because the alarm app failed. Please * do some research if you have any concerns about features included in this ROM * before flashing it! YOU are choosing to make these modifications, and if * you point the finger at us for messing up your device, I will laugh at you.
FREQUENTLY ASKED QUESTIONSQ: The room is bootlooping the first time I attempt to boot into it after clean flashing. What should I do?[/COLOR]
(Please read them BEFORE posting anything in the thread!)
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.

If your currently installed ROM is any version of either: stock Samsung TouchWiz, LineageOS, CyanogenMod, or any other custom ROM, you must perform a clean install of that LineageOS 17.1 variant, which corresponds to the model of your tablet!FULL WIPE (with external microsd card)
How to flash LineageOS and Open GApps
FULL WIPE (without external microsd card with NO Home PC access)
FULL WIPE (without external microsd card with Home PC access)
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 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!

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

TWRP 3.5.2_9-2
The official TWRP for all four variants is built by TeamWin's servers from the outdated android-6.0 branch. A major bug in this branch is that mtp is broken, so I ran my own builds from the android-7.1 branch. I fixed hw encryption, which is why I bumped the version number up to "-2":
twrp-3.5.2_9-2-gts210velte
twrp-3.5.2_9-2-gts210vewifi
twrp-3.5.2_9-2-gts28velte
twrp-3.5.2_9-2-gts28vewifi17Since all ROMs got deleted and it looks like there won't be any new ones I decided to do something about this.
My T719 is still in perfectly good shape and it would be a shame to dump it to the landfill.
So I spend the last two days digging through Repositories and recreated the build processes originating from ripee's original post, giving these devices a second life.

Yes, I'm almost done reviewing my commits so far. Real life is busy lately.
