Thanks.

So I tried all of the available lineageOS builds that I could find (Don's, the one linked to on the other forum and secretwolf's), and all are fairly stable, however I have an issue with a game called Empires and Puzzles and that it freezes up once in a while, but only on secretwolf's and the one from the other forum. Don Carnage's build hasn't froze on me (yet).

If I'm completely honest, though, the other two builds ran the game considerably more smooth. Perhaps the other builds are tweaked more for performance and my GPU is overheating? The game is not very graphically intensive, but I realize that this is a fairly old tablet.

tl;dr: on my N801x, this build seems to be the most stable, but performance seems a bit worse (which is maybe why it's more stable).

Hi everyone. Could I get some clarification of the WiFi issue?

Issue: I can see and select the WiFi, enter the password, but it won't connect. On stock ROM, WiFi works fine.

Device: N8013, did the issue occur on this one or other ones?

My setup: macOS 10.14 Mojave & Heimdall v1.4.1 to flash TWRP

1st run: twrp-3.2.3-n8013-n2.img (Don Carnage thread), lineage-14.1-20190312-UNOFFICIAL-n8013.zip (aka N6), open_gapps-arm-7.1-nano-20191126.zip

2nd run: Searchring thread for "wifi", seeing the hint to flash "1st version". Flashing lineage-14.1-20181231-UNOFFICIAL-n8013.zip (aka N2, there is no N1 for the 8013) and GApps

3rd run: Trying lineage-14.1-20181103-TESTING-n8013.zip (from secretwolf98's thread)

For those for whom installing the "1st version" worked, what did you use? The build in android-hilfe.de does not have a N8013 version. Only N8000, N8010 and N8020.

EDIT

I got it working! Apparently it can be solved by changing my WiFi setup. I disabled PMF (https://www.wi-fi.org/knowledge-center/faq/what-are-protected-management-frames) and AMPDU (https://routerguide.net/optimize-ampdu-aggregation-on-or-off-a-mpdu/) and it worked. Still, it worked with the stock ROM with these setting enabled, but disabling them make it possible to connect to my WiFi.
[Galaxy Note 10.1 Android Development] Don Carnage:
As mentioned somewhere in the thread, the wifi issue only sporadically happens. If it won't connect, usually doing another flash with a complete wipe helps. I'm not exactly sure about the preconditions that lead to the issue but my guess is that it has to do with the nvram settings as I had similar trouble with the mainline kernel until I found the right settings file. Unfortunately I could not reproduce it until now so I could not check. What is currently bugging me the most is that after reflashing the problem is actually gone and that is very atypical so it must be some kind of race condition but on a per flash basis. Those are usually the best of all bugs :silly:
[Galaxy Note 10.1 Android Development] Ectatomma:
This is a known Lineage OS limitation. One solution is to install Magisk instead of supersu (https://xdaforums.com/apps/magisk), then download the miracast enabler module by VR25 at https://xdaforums.com/apps/magisk/module-miracast-tethering-enabler-adb-t3611335, then install the ZIP using Magisk Manager (open the Magisk Manager menu, tap modules, tap the tellow circle with a +, then choose the module ZIP and install it.

I used Don’s source code to compile LineageOS 14.1

The n8000 build will be added later, that is currently being compiled at the moment. Keep an eye out on the link for that build. The n8013 and the n8020 builds are currently out. These builds are freshly synced with the latest LineageOS source code.

[Galaxy Note 10.1 Android Development] starflower:
It's really these two settings. The issue occurred within the same flash. Boot, no connection, change WiFi settings, connection. Now that everything is running fine, once I change my WiFi settings and turn PMF and AMPDU on again, it also can't connect anymore.

I deleted backups accidentally, Can i possibly go back to stock rom when i need to do so,if possible where can i get stock rom

---------- Post added at 07:15 PM ---------- Previous post was at 06:34 PM ----------

The tab with this version was somehow running smoothly but not after it started the following

•MTP keeps stopping

•the phone keeps restarting each and every time

•apps stops to run every now and then

•some games i used to play con not support anymore

Do these probs have anything to do with this rom

Battery Percentage Remaining and Shutdown Problem GT-N8013

This problem was evident using the following ROM's:

lineage-14.1-20190312-UNOFFICIAL-n8013 and

lineage-14.1-20191129-UNOFFICIAL-n8013

I was using lineage-14.1-20170810-UNOFFICIAL-n8013 for about 1 1/2 years and have not gone back to that ROM to test as of yet but I do not remember having the battery issue back then. So before I go back to the " lineage-14.1-20170810" and test it (because the newer ROM's corrected a few issues) I wanted to toss this out here and see if anyone had any relevant feedback.

I recently replaced the original battery in my N8013 because the old one was not lasting as long / discharging a little faster and the tablet would power down when the battery level got below roughly 10-20%. So with the "New" battery the tablet appears to have the same problem. Charges to 100% and then while the tablet is laying around discharging it will power down as soon as it gets down to around 30%. If I am actually using the tablet when it reaches 30% it seems to last longer while discharging as opposed to the tablet laying around discharging. If I then power the tablet back on after it had shut down the battery percentage remaining could be roughly anywhere from 0-20%. Then I recharge to 100%.

1) As with ALL my devices, I do not leave them charging all the time thus creating a "battery memory" and helping to increase the performance and life of the battery.

2) I remember reading in a thread somewhere that incorrect battery percentage / shutdown issue could be a ROM problem?
[Galaxy Note 10.1 Android Development] JJEgan:
<As with ALL my devices, I do not leave them charging all the time. I remember reading in a thread somewhere that this could be a ROM problem with incorrect readings of battery remaining percentage? >

No not true as battery calibrates itself and battery stats are rebuilt every full charge .

leaving on charge overnight etc can lead to Nand fail .
[Galaxy Note 10.1 Android Development] johnny88:
Hi, amazing Rom, only 1 issue: it never goes in deep sleep.

I've tried with tuning "ondemand" threshold 60 and 65 but no deep sleep states detected on Kernel Auditor.

Battery Percentage Remaining and Shutdown Problem GT-N8013

My Bad! I did not mean to combine the two comments. They were to be separate.

Comment 1:

As with ALL my devices, I do not leave them charging all the time.

I was simply stating my practice of not leaving devices overcharging or extended charging periods.

Comment 2:

I remember reading in a thread somewhere that this could be a ROM problem with incorrect readings of battery remaining percentage?

This was supposed to be a comment regarding a ROM in general that may show/cause incorrect battery percentages.

In reference to a post I made on page 60 regarding Battery Percentage Remaining and Shutdown Problem for the GT-N8013 : https://xdaforums.com/showpost.php?p=81292539&postcount=600
[Galaxy Note 10.1 Android Development] eChino:
After applying the kernel tweaks from boeffla, most things work fine. Battery warning does not work, just drops from 15 to 0% and shuts off, but that might be due to the old battery I have.

Another thing: I used to use SNote In KK times, but on this rom the apps (no matter which Version) crashes immediately after start. Are there libs missing or something similar? Can I get it working? Lecture notes works flawlessly.
[Galaxy Note 10.1 Android Development] Don Carnage:
I'd have to try this myself. Haven't been very deep in this subject until now so I can't give any useful info here. How is the battery drain for you with no deep sleep?

I also have one device which has an issue with battery percentages. It jumps around a lot in TWRP after flashing and I haven't seen this behaviour on my other devices. As I already switched batteries and this didn't help at all, I guess it's an issue reading the values from the max chip.

Edit: for the apps, I don't know what's wrong there. I don't use them at the moment.
[Galaxy Note 10.1 Android Development] johnny88:
My n8000 is off from weeks (it's a spare device) so I don't remember exactly, but I can say 4-5% /h more or less, if needed I can turn it on and give an accurate feedback in a couple of days

:)
[Galaxy Note 10.1 Android Development] Don Carnage:
So basically the battery was empty in a day even if not used, is that correct? That would be way off from what I currently experience. If that's the case, could you provide a log file after it has been lying around for a couple of hours once you get it up and running? That would be of great help.
[Galaxy Note 10.1 Android Development] secretwolf98:
The battery dies very fast on my n8013 if I use it. But if I don’t use it, it’s gets to 50% after a month or 2 months of not using it and not charging it.

[Galaxy Note 10.1 Android Development] pdbc:
Me too. No deep sleep. In half a day of no use (definitely NO screen on) it lost almost -60%. I checked with wakelock apps, and for real I found 0:00 deep sleep time, so the device was always awake.

I'm not an expert, if you can explain me how to give you log file or whatelse, I will support you without any problem.

This ROM is unbelievable smooth and fast, so thanks for your work on it. I'm using this wonderful device almost every day since 2012, but now I need to upgrade OneNote and some other apps I need, so I was obliged to flash a custom ROM. That said, I'm very willing to support your development if I could as beta-tester.
[Galaxy Note 10.1 Android Development] TrainingMatador:
Have you ever performed a battery check and or battery calibration?. I used to have that problem with KK, I don't have battery issues now with this rom, but it eat battery when watching videos or playing, even with battery save mode in battery settings (different from the battery save mode in phones, that's another bug from this rom).

Also bear in mind that a battery from 2012 must be dying already, you can get spares from aliexpress.
[Galaxy Note 10.1 Android Development] JJEgan:
)Have you ever performed a battery check and or battery calibration?.)

You cannot calibrate a battery its done onboard the battery > see millions of posts on the subject .
[Galaxy Note 10.1 Android Development] pdbc:
It is not this the problem. As I wrote, CPU goes NEVER in deep sleep. And the battery with KK lasts more than a month in stand-by.

---------- Post added at 12:04 PM ---------- Previous post was at 11:54 AM ----------

Moreover: I use my tablet without SIM Card, so in Airplane-mode. If I check the Battery Information, I can see all the battery is drained by "cellular network", even if the tablet is in Airplane-mode. It seems a little strange, doesn't it?

Genuine Note 10.1 Keyboard Dock Not Working

I appreciate the efforts on this ROM. I'm curious if anyone uses the stock Samsung keyboard dock with this ROM? I have 8013s and 2 docks. The charging works but keypresses are not recognized on both. I just came from a different LineageOS 14.1 build from 2017 and the dock works great with that build. Any pointers or feedback appreciated as I've checked all of the obvious items that I can think of.

Thanks!
[Galaxy Note 10.1 Android Development] pdbc:
Here is attached a log as Don asked. Steps I took:

Tablet charged 100%

Disconnected from power supply

MatLog in recording mode (9:26)

Screen off and tablet left alone for a lot of hours

Screen on

MatLog stopped (19:20)

That's all. From 100% to 84% with no screen activity.

As I said, usually I'm using this tablet always in airplane mode (no SIM card inserted), activating WiFi only when I need. And as I said, the drain with original KK ROM was very low (in a week of screen off, I lost usually <10% of the battery). I'm not talking about one year ago, I'm talking about beginning of February, before I installed this wonderful Custom ROM. So, it is not a problem of my old battery or whatever some others may think. It is a problem of NO DEEP SLEEP, as confirmed by Wakelock Detector.

I'm available to conduct all the tests which you think could be useful to fix this.

Thanks.

EDIT: I conducted some tests, and the result is that the problem is in the radio module. I installed the ROM for N8013 (so for the WiFi-only version) and deep sleep works without any problem. So I was right when I said

[Galaxy Note 10.1 Android Development] Don Carnage:
I recently bought all the accessories I could still get and the keyboard dock seems to work fine for me, writing is possible without any issues, locking/unlocking the device with the dock, etc. and it's charging. Did you do a fresh install of the ROM including wiping files from the old ROM?
[Galaxy Note 10.1 Android Development] pdbc:
Yes, I used the adviced zip file: addonsu-14.1-arm-signed.zip. With this, I installed only "kernel adiutor" to check the frequency used by CPU. No other apps so as to go on with the test. When I was sure, I installed "MatLog" to download logs.

Moreover, I installed your custom ROM and [MENTION=8036553]secretwolf98[/MENTION] custom ROM for N8000 (lineage-14.1-20181027-TESTING-n8000.zip and lineage-14.1-20191207-UNOFFICIAL-n8000.zip) : the problem is the same for all the Lineage custom ROM for N8000.

To be honest, now with the modified ROM (lineage-14.1-20190312-UNOFFICIAL-n8013.zip adapted to be installed on N8000) I'm very fine. I don't need the 3G module for now, so my Note 10.1 is again on the cutting edge!

Boot problem

Hi,

I have installed the ROM on my tablet using the instructions provided. And it did work. I installed the ROM back in November 2019. However, yesterday the WIFI stopped working, getting stuck on "Turning on Wi-Fi". So I followed the instructions and reflashed, wiping Dalvik, System, Data and Cache. I seem to be stuck on the lineage-os startup screen. I've tried letting the device startup for over 10 minutes and that has yielded no results. The /proc/last_kmsg is in the Google Drive link below since my system clipboard can't really copy the amount of text in the file. Also, there are some corrupt characters in the file for some reason.

https://drive.google.com/file/d/1abQQOXQqx-LPnS3EuIBK79W7viMbek4W/view?usp=sharing

Summary:

My device model is GT-N8010_CHN

The system is stuck on the LineageOS BOOT Screen (the animation was still moving).

My TWRP version is 3.3.1-0 installed using twrp-3.3.1-n801x-v1.img

The ROM file I tried installing is lineage-14.1-20190312-UNOFFICIAL-n8013.zip

The OPEN GAPPS file is open_gapps-arm-7.1-nano-20200418.zip

The system does boot on stock ROM. I tested this yesterday (Nandroid Backup).

I did not reboot between ROM install and LineageOS install.

It did work from November 2019 to April 17th, 2020.

Any help is much appreciated,

Thank you

Instructions are in the 3rd post.

You can also refer to this guide for a more detailed explanation in the 2nd post:

https://xdaforums.com/showthread.php?t=2102677

Only that instead of CWM recovery, use TWRP.

And instead of install SuperSU you want to install the ROM (lineagexxxx.zip)

[that means, ignore step 17 onwards from the other thread and replace with step 5 onwards from this thread]

Hopefully this is clear enough.

Well after using this ROM for 4-5 days I can report this on my N8013. Random reboots for no reason at all... maybe 2-3 times a day. Heavy on my system memory and tends to slow things down after a while. I have gone through all my apps and close them often to help with this. Most programs work but I was getting tired of hitting a button and waiting 2-4 seconds for any responses. That could have been at my end.

I finally went back to CM Unofficial 13.0 (Android 6.01). It works so much faster with the same apps!

Thanks to the OP for trying. Hopefully ppl will continue to work on this. :)
[Galaxy Note 10.1 Android Development] Don Carnage:
Did you follow the installation guide, including wiping all the partitions? It's working smoothly for everyone who follwed the instructions.

The only thing that is sometimes an issue is WIFI which usually can be fixed by another clean installation of the ROM as stated in the Q&A.
