[Samsung Galaxy Tab E  ROMs, Kernels, Recoveries, &] AndroidAction:
Hello,

Thanks for your efforts.

As the first time doing this, I wanted to record my experience for others. Here are most of the steps I followed.

You need:

-microSD card, at least 16GB

-microUSB cable

-laptop

-battery should be fully charged

-this took me 6 hours from visiting this webpage until logging in to my first new app. Hopefully I can save you some of that time.

Backup

-you can back up through the cloud, through a pc app, or just copying the files

Cloud backup

-swipe down from top, tap gear (Settings)

-tap cloud and accounts

-tap Samsung Cloud

I never set this up so I don't know what else to do here

File backup

-download https://toolbox.iskysoft.com/backup-android/backup-android-stock-rom.html

-it helps you make some settings, but go to settings, about, software, version, tap 7 times, turn on developer mode. while you're there, enable OEM unlocking

-do the backup. it makes a .bak file but this is really a zip and you can open it. Check what's inside. If you think anything is missing, back it up separately.

Find out your passwords

-you should write down passwords and login details to all your apps, and even list out the main apps you use

-find out your wifi password

Insert SD card

-use whatever means to copy the custom rom to the sd card. I used a usb sd card reader.

-copy the android 13, arm (32 bit) zip from mind the gapps

Download MindTheGapps: Custom Google Apps Package for Android

Looking for a reliable source to download the MindTheGapps package for your Android device? Look no further! At MindTheGapps, we provide you with the latest

mindthegapps.com

-copy the fdroid apk here (optional):

F-Droid - Free and Open Source Android App Repository

F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.

f-droid.org

-I found later on it helped to insert the sd card once while the device is on. The device seems to initialize something, and a few files show up.

Recovery install

-I tried Heimdall but couldn't get it to work. Loading the rom package gave

firmware.xml missing

there's a way around that and you need to download the PIT, but trying to connect to the device gave

ERROR: Claiming interface failed!

or other errors. I tried all the usb drivers with Zadig, a reboot, restarting the device etc.

-get TWRP_3.5.2_9_SM-T560NU_20211015_Unofficial.tar from

retiredtab - Browse /SM-T560NU/TWRP at SourceForge.net

sourceforge.net

-get Odin from https://www.osamsung.com/

-I didn't need to install any drivers, win11 had them

-run Odin

-boot device to download mode with

Download: With the device powered off, hold Home + Volume Down + Power. Volume Up to continue.

to get out of download mode:

Volume Down + Power.

-Odin should show device detected, and windows device manager will show Samsung modem when it's in download mode

-click AP, select the TWRP tar file.

-click Start. it doesn't take too long. device will reboot

Stock ROM backup

-reboot into recovery mode.

With the device powered off, hold Home + Volume Up + Power.

-twrp starts

-change destination to sd card

-do default backup. this does not include your documents.

-/external_sd/TWRP/BACKUPS/...

-I had about 10GB which took 12 minutes.

Wipe

-do a default factory reset/wipe from twrp

Install custom ROM

-tap install, find the rom zip you put on the microsd card

-I've seen it recommended not to install the gapps zip at the same time

-reboot

First boot

-welcome to Android 13! Swipe up instead of left to get started

-go through the setup. you will need your wifi password

-it seems pretty fast at this point. install the f droid store, either open the apk you put on your microsd card, or download it again with the browser

-install the Aurora store. Now you can use that as the google app store

Gapps

-unfortunately, you will find that many apps complain that Google play services is required. Snapchat, Textnow, banking apps, fall into this category. I found it not practical to avoid Google.

-reboot to recovery mode again, add the gapps zip and install. reboot.

-you will find everything much slower, nearly unusable. Don't open too many apps at once. It will work with 1 or 2 apps running. You need to learn how to close apps in the new android; tap the button to the left of home on the bezel, this gives you a card view of running programs, and swipe up on top of a running program to close it. Tap one of the cards to bring it full screen.

Usability

-you can't run too many programs at once

-due to the slowness, I constantly had unresponsive program notification, tap wait

-it can become unusably slow. best to restart and run one program at a time

-play services is essential for many popular programs

-all your old documents are still there, but you have a backup just in case

-it will take a long time to login to all your apps. Start by getting your SMS working, you will need codes to set up your apps.

-I still can't load gmail and some other apps, it just disappears suddenly.
