    CHANGELOG

    v1. Initial release for Android 8.1


    1) DOWNLOAD

    - djibe Galaxy Tab 2 pack: https://bit.ly/djibe-galaxytab2-pack
    (contains Samsung tweaked Odin 3.13.1 + Samsung USB drivers + TWRP 3.4.0-0 official recovery + Magisk Root + Aurora Store). Unzip files.

    ### GPS and Camera don't work. Use an Android 7.1 ROM if you need these

    + BitGApps Package ARM 8.1 (R44+): https://forum.xda-developers.com/t/custom-gapps-bitgapps-for-android.4012165/post-81060605
    Download latest build: https://github.com/BiTGApps/BiTGApps-Release/releases

    + 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,
