[GUIDE/TUTORIAL/HOWTO] Samsung Galaxy Tab 2 (7 or 10") from Stock to Android 8.1

[mp3catcher]

I have installed with the odin tool v3.13.1 immage twrp-3.4.0-0-espressowifi.img.tar.

Then i have follow the manuel as above. And now i seen no apps i think that i do something wrong in Clean wipe and flash ROM + GAPPS.

 

[mp3catcher]

You can't flash arm64 gapps on arm (v7) device and expect it to work.

oke help me, with version i have to install on my device?

 

[mp3catcher]

I started all over and now everything works fine. Thanks all for the feedback

 

[davemfox]

Well first go around and this 8.1 seems to work a lot faster than the 4.4.2 that I've just upgraded from!

Got to say that the instructions are spot on and there was no issue installing on my P5113.

Only comments I have are:
Why do we need Magisk?
I installed Firefox version 105 but this didn't work and kept rebooting the tablet, so I've uninstalled that and am now using DuckDuckGo.

[davemfox]

Ok I figured out what I need Magisk for - I missed a line in the OP's instructions.

For those coming in cold on this and updating an older device, you need to be aware that the Magisk*.apk file downloaded from github needs to have its extension changed to *.zip.

Hi, can you wipe partitions, Reboot to Recovery and flash after reboot ?

 

[rgorgory]

Thank you very much on this step-by-step tutorial.

I have a question. Is there a way to improve the limited amount of memory on Galaxy Tab 2 7.0"? I own an unmodded GT-P3113 and i can barely open any app without it crashing, nor browsing internet and even less gaming without it crashing

years ago, I read somewhere about sharing memory with a swap partition with SD card, is that still possible with this ROM?

Hi, we've been using https://github.com/MightyM17/android_kernel_ti_omap4/ as the kernel for all builds later, I've tried adding zram/swap but the it failed to work, you could give adding those commits from 3.4 torvalds tree a try

 

[rgorgory]

Thanks for answering. but sorry but i did not understand. I dont have any knowledge about kernel and even less how to install it. can you please explain?

+ a microSD card. Copy ROM, Gapps, Magisk root and Aurora Store on microSD card (FAT32 format) and insert it in phone.

+ Charge phone to 100%


2) BACKUP DATA

Install Samsung drivers (you unzipped earlier).
Then plug phone to PC in File transfer mode.
Collect all .jpg or .mp4

Use app like Backupyourmobile and SMS backup & Restore to backup contacts, etc.
Check that backup is located on microSD card.
Then copy the backup on your PC.

Now connect to Wi-Fi, Settings > About device > Software update. Check you already have the latest.


3) FLASH TWRP 3.4 RECOVERY

Shut down tablet.
Boot in Download Mode: hold Power + Volume- until you see Warning's screen and release all buttons.
Confirm access to Download mode by pressing Volume+.

Connect tablet in USB, wait during bootloader drivers installation.

Then launch Odin.exe (included in my archive) and wait for Odin indicator ID:COM to become blue.
In options: Verify re-partition and Auto Reboot are NOT ticked while F. Reset Time is ticked.
In Files > PDA > select twrp-3.4.0-0-espressowifi.img.tar
### or twrp-3.4.0-0-espresso3g.img.tar for 3G model.

### Warranty will be Void after next click ###
Click Start.

When Success green message appears, unplug USB.
Now hold Power + Volume+ until Samsung logo shows up and release buttons.

### If tablet reboots normally, recovery will be reset. You can flash TWRP with Odin again.


4) BACKUP SYSTEM (Nandroid backup)

Wait a few seconds for TWRP recovery to boot.
Recovery asks for Keep System Read Only ? > Swipe to Allow Modifications.

Go to Backup > you can select the partitions you want to save.
I prefer to backup System, EFS and Boot.
Now type Select Storage > Select Micro SD card and confirm with OK
Now Swipe to Backup and wait during process.
Go to Home screen and continue with next chapter.


5) FORMAT PARTITIONS

Go to Wipe > Format Data
Type yes and confirm with bottom right icon.

Go to Home > Reboot > Recovery > Do not install app.

Back to TWRP, go to Wipe > Advanced wipe,
select Dalvik, System, Data, Internal Storage (if you really made a backup from step 2), Cache, then Swipe to Wipe,
then back.
### Don't select microSD or you will lose your backup

Go to Home > Reboot > Recovery > Do not install app.


6) FLASH ROM, GAPPS

Go to Install > choose ua_expresso*.zip,
(if you don't see the files, tap on Select Storage and make sure Micro SDCard is active).
then Add more Zips > bitgapps*.zip
then Swipe to confirm Flash.
Wait for operation to end.

Then tap Wipe cache/dalvik, swipe to confirm,
then Reboot System.
Wait for the phone to boot during 5 minutes.

### Don't connect to your Google account before setting up root.


7) IMPROVE

Go to Settings > System > About tablet
### Wi-Fi users, don't be scared, Galaxy Tab 2 3G is written, not a big deal.
Tap on the "Build number" entry seven times. You are notified that developer settings are now active.
Go to Settings > System > Developer options,
Set Windows animation to 0, Transition animation and transition scales to x 0,5.

If Netflix or Disney+ are not accessible from the Play Store, use Aurora Store.


8) STORE YOUR BACKUP IN A SAFE PLACE

Connect phone or microSD to PC.
Open microSD folder and backup TWRP folder to a safe place.



Enjoy,

Looks like a P3100 so should use espresso3g zips, also after clearing system, cache and all, reboot back to recovery, that should make it work.
Also use andi34's twrp

Gapps will inevitably slow down the tab to a crawl, is it necessary to use them?
