Thanks for that, honestly you could easily create your own thread for newer LOS builds on this device. There's barely anyone building for it nowadays and I think it would make a lot of people happy.

Obviously just give credits to nels83 and post the sources, you should be good to go. ;)

I would definitely flash your newer builds if you made them available. XDA is all about sharing. :svetius:

[Galaxy Tab 3 10.1 Android Development] mzurhorst:
Hello,

I tried to upgrade my moms old tablet for my son. I thought I was following the instructions step by step, but I am stuck somewhere.

1. With Heimdall on Linux, I managed to flash TWRP.

2. From within TWRP, I wiped cache and data partitions, and flashed both the ROM and GApps.

3. The reboot yields a new animation (arch with a circle), but nothing else happens.

I was reading that the first boot would take a long while. Now I sit here after 9 hours and wonder whether this is really correct or something is missing. How long is "long"?

Thank you for your time and help.

Kind Regards,

Marcus

You need to wipe data, internal, cache, dalvik and system then flash ROM and gapps.

If you face an issue of not booting then remove your SD card and reboot and it should work (weird bug I know, but it works)
[Galaxy Tab 3 10.1 Android Development] icantlogin:
Hi Marcus,

It's not supposed to take 9 hours hehe. More like 10 minutes, so something's definitely not right! Do you have an SD-card in the tablet while booting? Try removing it, I think I read somewhere that for some first boot doesn't work with an SD-card present.

Otherwise I don't know... try flashing again and carefully read all the output from TWRP to see if anything goes wrong while flashing the ROM or GApps. See if it works without GApps. Search this thread to see if others had the same problem.

Good luck!
[Galaxy Tab 3 10.1 Android Development] mzurhorst:
Ok, I feel kind of save because I can still enter TWRP :silly:

1) I wiped all the partitions once more and flashed over from scratch.

Same result, regardless of having the SD Card inserted or not.

2) Now I was wiping again, and flashed only the ROM, but not the GApps.

Also the same issue.

The only thing I see in TWRP is two red lines: "E: Unkown command". But from what I understood in this thread, this can be ignored.

No other issues are reported.

So, am I correct that I do not have to root the phone or so? -- Or is this question so stupid because everybody assumes I did this anyways?

--- I really only flashed TWRP via Heimdall and nothing else so far. The root stuff was confusing and not really clear whether required or not.

Thanks & Regards,

Marcus

[Galaxy Tab 3 10.1 Android Development] mzurhorst:
I was following the link from the 2nd post: ROM - Beta 5 (20190408)

[Galaxy Tab 3 10.1 Android Development] mzurhorst:
Some success at least.

I found an image for the stock version 4.4.2. This one flashed well and the tablet is again in the starting condition.

But flashing the LOS is again not working.

[Galaxy Tab 3 10.1 Android Development] iAbadia:
First of all, thanks for this, you've brought my tab 3 back to life!

Now, I'm trying to use Magisk (and MagiskHide) to root and trick certain live TV app into thinking it's not rooted. Magisk is flashed and it passes safetynet but the MagiskManager app takes ages to load, the hide doesn't work and it shows as disabled when reboot. I checked the logs, shows a recurrent error (bad file descriptor), quick Google search and found a comment in a Magisk repo issue from a guy who had this same issue and fixed by rebuilding LineageOS with a kernel patch.

I assume this guy is using your unofficial build plus the patch and I was wondering if you could update the build with said patch.

Here's the link to the issue: https://github.com/topjohnwu/Magisk/issues/920

I was so happy to see that there were both updated images for TWRP and LineageOS... You're awesome!
[Galaxy Tab 3 10.1 Android Development] iAbadia:
Both TWRP and LOS updated, working fine with Magisk now.

Just a question, I've noticed that the lockscreen wallpaper is always black no matter to what image I change it to. Also, when I pull down the status bar the whole screen goes black until I push it back up. Is this some build.prop flag you've enabled or a graphics glitch? I've used that latest LOS image on your androidfilehost profile (lineage-14.1-20191020-UNOFFICIAL-santos10wifi.zip)
[Galaxy Tab 3 10.1 Android Development] James160103:
I was wondering about that too. Turns out the Low RAM flag is enabled in build.prop. Root your tablet and install a root explorer and navigate to System/build.prop and find the Low RAM flag and change it's value to "false" and save it. After that simply reboot and it should be back to normal again.

I've tried to install your ROM on my Wifi tab, but i've encountered some problems (boot didn't finish, arch linux boot screen), so i returned to nels' ROM. Maybe i did something wrong? Sadly, i need Gapps since i'm using some paid apps. Does the ROM work with (Open)Gapps? Do i have to install the boot image first? To to proceed for a successful install? Thanks in advance - i really appreciate putting effort in creating a ROM for such an "old" device :good:

Thank you again for your effort! Just one additional question: the download folder contains another image i didn't try to install yet: boot-20190714-santos10wifi.img - is this required for using your ROM? Should i flash it before flashing the ROM, or what should one do with that img file? Sorry if the question is dumb, i have almost no experience regarding Android development and system architecture...
[Galaxy Tab 3 10.1 Android Development] ddudek77:
I made a second try to to debug the problem, so I installed

twrp-3.3.1-3-santos10wifi.img

lineage-14.1-20191020-UNOFFICIAL-santos10wifi.zip

open_gapps-x86-7.1-pico-20200107

and again it works for me. Booting took about 3-5 minutes.

boot-20190714-santos10wifi.img was the image with intent to install on top of nels83's rom in order to remove problem with Magisk. So boot-20190714-santos10wifi.img is the same boot.img inside lineage-14.1-20191020-UNOFFICIAL-santos10wifi.zip

Does anyone have build instructions for this ROM/devices?

I was able to compile a build from scratch, but it doesn't boot properly (missing a library, can't start the window manager, a lot of fun stuff - I'll post logs later if anyone can help).

I am willing to setup a somewhat frequent build system for these devices (or at least the wifi variant) , but I need to first fix the bootloop issue.

EDIT: Found out why. Apparently the vendor file doesn't copy all of the required drivers needed for the GPS system, causing it to bork.

using Beta 5 (20190408) i still have issues with live video stream from skygo app

as nels83 explained in 2018 there is still some unfixed issue with live videos and resizing when streaming quality changes on the go.

video image gets crappy with squares like some kind of 3d image video, sometime green lines appear also.

Hope we get a fix for this ...

EDIT

The problem seams to manifest only when the tablet is rotated 180° with automatic rotation on and the image also rotates but it gets destroyed by this squares, as soon as you rotate back at 0° image quality is perfect.

same behavior with 20191020 by ddudek77 version BUT

bottom half of the screen is green in both positions 0° and 180°, while the top half behaves like 20190408, crappy image on 180° and fine on 0°

Magisk bugs

I've encountered some small bugs with Magisk v20.3 on GT-P5210.

1. Magisk Manager won't install after flash. (I had to install it manually.)

2. Magisk Modules not showing in Modules Tab after install but still work but some don't (e. g. YouTube Vanced doesn't work.)

I tried both nels83 build and dpdudek's build.

I'm going to try out the canary build, but I think that's not going to work.

If you want logs tell me which to copy.

EDIT: Magisk Manager Canary somehow works. YouTube Vanced is installed and shows up under the Modules Tab. :confused: (The new Magsik Manager looks ugly tho.)

If i remember correctly, you were using MicroG too. I got a problem there. Everything works, even Google Chrome. But i can´t log in there or in Drive etc.

When i start Drive, MicroG pops up to tell me i should login. But my account is already logged in, so it just says that there´s already an accoutn with that email adress.

Maybe had that issue too and got an idea?
[Galaxy Tab 3 10.1 Android Development] garylawwd:
Yes I run microg but completely gappsless. I don't have any Google apps installed so I don't know about signing into drive or any of that.

If your going to be using them apps you may as well just flash gapps. Something like pico package or something
[Galaxy Tab 3 10.1 Android Development] Schnoinsch:
I feel like Gapps slow the tablet down. I can live without, having chrome with my history and bookmarks would be convenient, also uploading into drive. Just a quality of life thing. I can use dropbox or airdroid also to get files quickly on to my tablet without too much of a hassle. Soon it will be backup tablet anyway, since i started reading comics and on the tab and i need a tablet with higher resolution for that, pref OLED.

Just thought it should work and i guess it´s a bug that it´s not working. I even get the "blabla login from new device" mail, but starting drive, it does not login via Mg. Instead it brings the loginpage again.
[Galaxy Tab 3 10.1 Android Development] garylawwd:
I use mega for backing up my photos, videos and files. And for web browsing I use fennec.

Both of these are good replacements for what you are using if you still want to use microg
[Galaxy Tab 3 10.1 Android Development] Schnoinsch:
It´s fine. Stock browser (or Dolphin) is sufficient and for quick filetransfer dopbox / airdroid is fine. Llike i said, would just have been a quality of life thing. This tablet won´t see any Gapps in its life anymore.

It´s really crazy how it is just not usable with Stock ROM and thanks to Nels, it works flawless. I wanna keep it that way until it has to retire. Already looking at Galaxy Tab 5S. But the measures they take there for people to not root / flash, are insane - pretty dangerous to customize it. Guess i will only debloat that one when i have it.

Anyway, thanks for your answers.

P5210 still laggish

Hi!

So i have a P5210 with the latest rom from Nelson with android version 14.1-20190408-santos10wifi and with f2fs system.

Just to know the experience that everyone has with this tablet is laggish for almost any app...

Thinking of installing a older rom (maybe lighter for the tablet).

Surfing on the net is ok, but other apps is just lag!! Too much lag! Like Nike Training app... Takes forever to launch...
[Galaxy Tab 3 10.1 Android Development] garylawwd:
Go gappsless and use microg and it's actually impressive for an old slugger.

You are more than likely using a heavy version of gapps which kills system speed and stability in something so old.

If you use gapps use nano or pico.

This rom is a hell of a lot faster than stock so it just sounds like your system is being raped by Google services
[Galaxy Tab 3 10.1 Android Development] CamoGeko:
The biggest failure of these older tablets is the miniscule 1GB RAM, even 1.5GB would have been better.

I'd put it more down to hardware limitations than using GApps. I personally tried Micro, Pico and Nano and they all present the same stuttering issues after a while. A simple Reboot usually fixes it. ?

You can also use an app called ftrimmer.

Sent from my onyx using Thebear Blue XDA Labs
[Galaxy Tab 3 10.1 Android Development] garylawwd:
Yes I would certainly agree there, 1gb of ram is not sufficient nowadays.

This is why I suggest microg as it uses less than a quarter of the ram which play services uses in the background.

For me the performance increase was substantial with less lags and freezes (obviously not perfect but certainly a hell of a lot better) even being able to play reasonably intense games like fwd assault.

I don't really use the tablet as much anymore just for recipes in the kitchen and light reading sometimes which it is ideal for

Hello everyone, I have installed the Lineage OS on my jurassically old Galaxy Tab 3 a long long time ago, but recently my mom has started to use it a lot as her ebook reader and the thing is that the default browser PDF reader is utter garbage, constantly bugs out sending her back to page 1 and doesn't have a "jump to page" function, I have tried using other readers from the Google Play store and most of them are irrevocably broken, not working properly and crashing one way or another, even Google's default PDF reader crashes to desktop. I've tried to Polaris Office as well but it's too damn slow for a simple PDF reader and it doesn't have a "skip to page" function either.

This file bool.img is the file extracted from lineage-14.1-20191020-UNOFFICIAL-santos103g.zip, so you don't have to install it. Other people had also problem with instalation (see previous posts), but I don't know why. Maybe try again steps:

- install stock rom

- install nels83 rom

- after that maybe try again lineage-14.1-20191020-UNOFFICIAL-santos103g.zip
