[DEPRECATED][ROM][diOS][N] Samsung Galaxy Tab A 7.0 LTE SM-T285 (gtexslte)

This is discoveryOS (diOS)

Code:

/*
* I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
* Please do some research if you have any concerns about features included in the products you find here before flashing it!
* YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
* Your warranty will be void if you tamper with any part of your device / software.
* Same statement for XDA.
*/

• fully based on /e/ OS for a full google-free experience
• F-Droid (OpenSource Apps as an alternative to Google Play) including extra repos
• debloated everything not needed for diOS (for details check this list)
• Integrated MagicEarth Navigation
• Integrated Automate App
• Integrated Aurora Store
• Speaker output optimized for speech (i.e. increasing loudness as much as possible)
• my builds come with full OTA update support (from v2.0 on)
  (... you know that thing which informs you that a new update is there and where you just click to download + install)

• Implementing Kiosk Mode for navigation only (might be provided as a separate build)
  links: <--- abandoned by using the app "Automate" instead

• Integrate my created Automate flow to simulate a KIOSK mode (i.e. start navigation on boot and keep it on top always)

• Your device need to be unlocked (seriously?!)
• Latest TWRP/SHRP build is highly recommended, e.g. mine: see my recovery post
• Do a full Nandroid backup before doing anything else!
• Samsung STOCK firmware should be on T285XXU0AQH1.
  You can check your current firmware version in Android -> settings -> About / Phone info -> Baseband version
  If you like try first without flashing this firmware but if you encounter any issues upgrade to this version first before reporting
  Fast and (afaik) good site for downloading: https://sfirmware.com/samsung-sm-t285/
  (scroll down and type T285XXU0AQH1 in the search box, choose the one for your country, download, flash as usual, flash TWRP/SHRP again, flash this ROM)

1. Backup
2. When you flash diOS the first time:
   Wipe: System and do a factory reset !
   A LOT of bad stuff can happen otherwise
3. Flash the ROM
4. Optional (if you want root): Flash Magisk
5. Flash OpenGapps ????? STOOOOOOOOP NO No no! you don't want that on a google-free phone! diOS contains everything you need to live without Google!
6. Boot (be patient on first boot!!! SIM detection might take a minute after the FIRST boot after clean flash as well)
7. Open Maps (MagicEarth) and click the download button to get your country/region maps
8. Open Automate to import the kioskmode flow
9. Open F-Droid -> Settings -> Repositories and choose those you want to enable (most of them are described here) & swipe down to update the repo list.
10. Open Aurora -> choose Anonymous as long as you don't want to have paid apps working
11. Enjoy

1. no OMS support! OMS is a hack DEEP in the android sources and all these are outdated now. if you need that use jedl's build
2. build is ENG , i.e. "adb root" will work and no auth required for ADB
3. bluetooth is working but using the blobs by jedld's build until I find the time fixing the android sources (unfortunately the repo of jedld does not contain the full history so I have to compare manually...). Until then I keep it like that.
4. not charging on USB connection (normal power supply works fine) - still investigating. Seems to be an issue with my kernel.
5. This ROM is just coming with BASIC stuff so several apps you might want to see in a regular Android ROM are simply not there.
   Examples (excerpt only!):
   - no Camera app
   - no Browser app
   - no Gallery app
   - no Email app
   - no Calendar app
   - no <fill-in-whatever-you-are-missing>
   the complete list can be found here always

For those interested I will also provide SHRP (skyhawk recovery) after some testing and fine tuning ...

• If you flashed a custom recovery already
• if you like to flash by download mode with heimdall

• If you never flashed a custom recovery before you have to use this one
• if you like to flash by download mode with ODIN or JOdin

• If you want to switch from TWRP
• if you want to upgrade from one SHRP version to another

1. boot to your custom recovery
2. push the IMG to your device (e.g. by adb)
3. select flash
4. ensure you select "IMG" (when in TWRP. when in SHRP that is not needed)
5. select the IMG file
6. choose "Recovery" as the "Target Partition" and flash
7. Reboot to Recovery to complete the setup.

1. boot to download mode
2. start ODIN/JOdin
3. put the TAR into the AP/PDA slot
4. ensure the "Auto Reboot" is NOT ticked/checked
5. flash
6. turn the device off (HOME+PWR+VOLDOWN) and directly switch just the VOLDOWN button to VOLUP when it wakes up and hold all 3 buttons until you see the recovery loading

1. boot to your custom recovery
2. push the ZIP to your device (e.g. by adb) (or start and use adb sideload and you are done)
3. select flash
