i forgot to mention that you can use the kernel aidutor app to control some of the settings of the kernel. In that OC thread, I think that I saw some suggested settings. It has been suggested that you do not play with the voltage.

Hello to all, new builds are up :)

March security patch included, credits go to gr8nole and Lineage. Cheers !

Welcome back cuberio. It's nice to see you and thank you for this update.

Will crdroid get one possibly? I'm not demanding by any means.
[Galaxy Tab 3 8.0 Android Development] cuberio1:
Thanx for your kind words nabril. It's nice to be around here and see that we all still enjoy our tab !

Unfortunatly all my last attempts to build crdroid failed. Otherwise I would have post new builds from time to time.

Can I dirty flash this over the latest crDroid build onnmy T310?

I would prefer to do a clean installation, but I would also prefer to avoid having to install all the apps.
[Galaxy Tab 3 8.0 Android Development] cuberio1:
You can try (after doing a backup through twrp), but pretty sure it wouldn't give good results.

I would recommend you to rather backup all your apps with oandbackup for instance, and restore them with it after a clean install.

Hi all,

I use [MENTION=3390537]cuberio1[/MENTION] build from March. It works great, thank you very much!

The ZXing Barcode Scanner has a problem though initialising the camera. It shows a distorted image and barcodes are not recognised.

Hey Folks,

I know it's been a while since I've posted anything. I finally had a bit of a break yesterday, and decided to spin up a virtual machine and run a new LOS 14.1 build. I have posted it on my AndroidFileHost for T310 only (4/28 build date). It has root built in, but you will need to install busybox if your apps need it. I have included the mountspace additions to the kernel that [MENTION=4968646]tigger2014[/MENTION] added.

I am now 2 weeks from finishing my degree, so I may have a little more free time to play around, but not sure if I will do as much as before.
[Galaxy Tab 3 8.0 Android Development] gr8nole:
Honestly, if I couldn’t fix it when I worked on it daily, I likely won’t ever get it fixed. Not having that device makes it practically impossible ( for me).
[Galaxy Tab 3 8.0 Android Development] Droehnemeier:
And again the same q o.O thx for for returning!
[Galaxy Tab 3 8.0 Android Development] celtic1453:
Hi,

Just Installed this ROM.

It is nice to see an old machine (coming from Android 4.4.2), running on Android 7.1.1.+ GAAPS.

Nο issues encountered so far.

And thank you for that!

I think though that it is a bit laggy ROM,

isn't it?

Is there anything I can do to make it a bit snappier?

SM-T310 version

I have installed the kernel.

Initially WiFi was dead

But found a solution to work around:

Solution:

Flash ROM+ GAAPS THEN

REBOOT.

ENGLISH LANGUAGE + USA SETTINGS TO WIFI.

THEN RECOVERY--FLASH KERNEL AND......REBOOT

AND WORKS FANTASTIC!!!!!!

THANKS man for reviving this pretty old machine!

[Galaxy Tab 3 8.0 Android Development] celtic1453:
After using the Most recent ROM+ Kernel the results are very good.

Very fast for this old machine......

The only issue is....the random turning off and then turning on of the WiFi.....

Even if the option

"WiFi always on while sleep" is active....

Any suggestions???

In any case fantastic results for such an obsolete hardware....

If you download Kernel Aidutor, you can control the kernel even more, but be cautious and careful and mindful and other adjectives. Don't play with the voltages, but do play with the governors. And senators. But don't touch the Speakers. Insert laugh.
[Galaxy Tab 3 8.0 Android Development] celtic1453:
Thanks.

I have been doing so.

The Tablet runs quite good for such an old hardware.

But one major problem still exists.

WiFi is keeping turning off whe the screen turns off......

even if the option "WiFi always on" is enabled, and battery optimization is set to allow background tasks like chrome , music players, e-radios, YouTube etc.....

Any idea....

this almost ruins the fantastic performance of this rom on this tablet...

Semi-noob question here. How do I unlock the bootloader on the Tab 3 8.0? I haven't worked with my tablet in a really long time and I don't remember all the ins and outs. I'm used to Samsung devices on which you go into the developer options and select OEM unlock. I see no OEM unlock on the Tab 3. Does it have the bootloader unlocked by default or am I missing something?
[Galaxy Tab 3 8.0 Android Development] nabril15:
It has been a while since any of us first did this since the device is old. I don't recall having to unlock the bootloader.

Search for the how to root thread, and you'll get the answer.

My tab 3 is a bit slow at no fault to the rom, it's an old device. I liked the speed of the oc kernel but also had the wifi issue without a fix. But as others have stated, the oc kernel works for some devices and not for others, even if they're the same model. Correct me if I'm wrong as I would love to get the oc kernel.

Have you tried running Trimmer (fstrim) ? It usually does wonder, especially on older devices that have never been trimmed.

Although it has apparently stopped working properly on my SM-T310 (= the fstrim command does work but running it again produces the same number of bytes trimmed, and I notice no performance improvement whatsoever).

Same as https://android.stackexchange.com/questions/156562/fstrim-not-working

ui_print("Target: samsung/lt01wifixx/lt01wifi:4.4.2/KOT49H/T310XXUBOD2:user/release-keys");

updater-script should now start with:

ifelse(is_mounted("/system"), unmount("/system"));

(. . .)

Otherwise installation will be cancelled by checking device

On Windows use 7zip or winrar and the normal Editor

On Linux file-roller or engrampa and gedit, mousepad or leafpad - there are plenty of text-editors :)

and now my wifi does not works.

I've exactly issue described in post #1:

If you have an issue with wifi not working AND your mac address shows a value starting with 02:00:00, do not post about it UNLESS you take a dmesg log (immediately after a reboot) and post it with your message. Google can tell you how to take dmesg log or see THIS thread.

so please, here's my dmesg log

hope someone can help to solve without reset my tablet.

I've also another question:

With xposed turned off tablet works well.

Any solution for having xposed working well?

- for Android < 8 (IIRC), Xposed + RootCloak (https://repo.xposed.info/module/com.devadvance.rootcloak2) worked great

- for Android >= 8, Magisk works to root and hide root, and I don’t need Xposed anymore

So may I ask why you need both Xposed and Magisk ?
[Galaxy Tab 3 8.0 Android Development] YnGWiE27:
Lineage root zip: first time i ear. Thanks, I will try it.

About xposed, i use it for lucky patcher, jasi patcher, and most important for me sudohide cause i use YouTube vanced so i need to hide vanced from play store otherwise i receive always notification for update YouTube app. Play store replace vanced with original YouTube app. Both patcher apps used xposed for works systemless. With lucky patcher i block Google ads services.

This is what I'm talking about.

May I suggest you to try either :

NewPipe (https://f-droid.org/packages/org.schabi.newpipe/)

WebTube (https://f-droid.org/packages/cz.martykan.webtube/)

SkyTube (https://f-droid.org/packages/free.rm.skytube.oss/)

All three are open-source YouTube clients that don't spy on you and most probably won't generate any notification.

And for the ads, there is of course AdAway (https://f-droid.org/en/packages/org.adaway/) ! :)

My advice :

Whenever you're looking for an app, first have a look at what's on F-Droid (https://f-droid.org/en/), and only if you don't find a suitable app, go look elsewhere like the Play Store. :)
