I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!

If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.

Instructions
1. Install custom recovery
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps
6. Uncheck Update Lineage Recovery alongside the OS option during start wizard

Work
Almost all

Known Issues
mtp buggy

P.s. for BiTGApps: Chrome workaround with gapps: Chrome should be a part of system app in Android R (11) but we install it as user app, which break sign-in and sync in chrome. To fix this, allow contacts permission for chrome. Restart chrome and you can add your google account.

Root
Install latest magisk (21.1+) from canary channel: https://github.com/topjohnwu/Magisk/releases/tag/v21.1

Recovery
Use official version from:

*** Screenshots ***



That's a great Christmas gift, thank you @Valera1978

Not working:

1) installing magisk

TWRP shows no error when flashing magisk (21.1), but it's not present in the rom. sometimes in the past magisk manager had to be installed separately in the rom. But the app only confirms, that magisk is not installed.

2) Audio Calls VoIP

Microphone is not working. Perhaps this can be solved like in the versions for LineageOS 16 and 17 by editing mixer_paths.xml. Therefore, root would be of much help

3) USB debugging.

after 'adb devices' the device is shown with the following comment:
no permissions (missing udev rules? user is in the plugdev group); see [http://developer.android.com/tools/device.html]

There's no authenthication dialogue asking for access from the computer for adb debugging. Maybe that's the problem

 

[q240627995]

fantastic!!! Thank you very much for your contribution!!!

@Valera1978 thanks very much for this nice Christmas present.
Before testing this, I have to test your other present for my P900.
You mentioned backing up EFS, but I've never found a TWRP (tested 2.8.7 up to 3.4) version which offers that on my T325.
On other devices I do have the option.

 

[bmwdroid]

Made a clean flash with data format.
I can confirm what @pocketrule wrote about installing Magisk 21.1.
Didn't test the other two points neither SIM yet.
Camera shows a picture upside down but doesn't take it.
Congrats and thanks @Valera1978 for this test build.

@Valera1978
If got SM-T320
On TWRP 3.4.x for mondrianwifi the efs backup exist.
I tried a clean install included data media
I can confirm Magisk stops with error, tried 20.4 and 21.1
Restored my data partion. Tab boots fine.
The Tab is very slow of all inputs.
THX for this Test Build.

Did you try Magisks 21.2? Haven't gotten around to it yet.

 

[mrmathematica]

Thanks for this. Among all devices I owned so far, SM-T320 turns to be the one that jumped the most android versions...

Magisks 21.2 doesn't work for me either.

Hello One question: what does installing custom recovery mean? I look for custom but if I did on officials not on custom and I would not want to mess up and be able to go back if necessary.
2) Flash you with which software
Bonjour
Une question: que veut dire installer la récupération personnalisée
Je regarde pour customisé mais si j'ai fait sur des officiels pas sur du custom et je ne voudrai pas me planter et pouvoir au besoin revenir en arriere.
2) Vous flasher avec quel soft

A+
Re-edition Too late I did with twrp
Ré-édition
Trop tard j'ai fait avec twrp

 

[bmwdroid]

......... and be able to go back if necessary.......

You can do that with Odin.
Flashing Samsung's firmware sets device back.

 

[gpinpin]

Good evening I no longer have access to the twrp recode section The tablet can be downloaded directly for odin So no access to whipe reset
The sound does not work but I cannot put root and go and modify the xml file mentioned above in the post

Bonsoir je n'ai plus accès à la section recode twrp La tablette peut être téléchargée directement pour odin donc pas d'accès à la réinitialisation du whipe
Le son ne fonctionne pas mais je ne peux pas mettre root et aller modifier le fichier xml cité plus haut dans le post
A+

 

[gpinpin]

Bonjour
Pas de possibilié de revenir dans le recovery. M'ouvre directement le chargement bouton volume haut et bas pareil.
Le son micro ne fonctionne pas par exemple dans messenger.
Les icones étaient trop petits
Une lenteur générale de la tablette T320
J'ai pu repasser sur la sauvegarde mais il a fallut trouver dans ce dédale de solutions difficiles à trouver de repasser sur l'origine puis refaire le root et enfin remettre la sauvegarde.
Je vais tester la version 17
Gpinpin

Hello No possibility of returning to the recovery. Directly opens the loading volume button up and down the same.
The microphone sound does not work for example in messenger.
The icons were too small A general slowness of the T320 tablet
I was able to go back to the backup but it was necessary to find in this maze of difficult to find solutions to go back to the origin then redo the root and finally put the backup back.
I will test version 17

@gpinpin which recovery do get into with Pwr+Home+Vol-up?
Or isn't any accessible?
Don't really get in which state your device is.

 

[gpinpin]

Pwr + Home + Vol-up? = Pwr + Home + Vol- Down ? impossible recovery
I was forced to flash odin

 

[bmwdroid]

Pwr + Home + Vol-up? = Pwr + Home + Vol- Down ? impossible recovery
I was forced to flash odin

Pwr + Home + Vol-up leads to recovery
Pwr + Home + Vol- down and you get into download mode

 

[gpinpin]

[QUOTE = "bmwdroid, message: 84251211, membre: 5763685"]
Pwr + Home + Vol-up mène à la récupération
Pwr + Home + Vol- down et vous entrez en mode téléchargement

@gpinpin translation seems ok although my french is a bit rusty

 

[lahuindai]

@Valera1978 as always a brilliant job and thank you very much.

Anybody else getting the "serial console enabled" message ?

I wonder if that might be what is impacting the UI speed ?
