Here's a story about making an old Galaxy Tab 2 10.1 (GT2-10.1) still relevant today. Most of the thanks has to go to the folks at LineageOS and the other people that maintain repositories for Apps (AKA Programs) and are not Google, plus the people that created the TWRP (TeamWin Recovery Project, which has nothing directly to do with Microsoft Windows).

Test Subject - Samsung Galaxy Tab 2 10.1

Model Name: Samsung Galaxy Tab 2 10.1 WiFi tablet

Model #: GT-P5113

NOTE: The entire A9 / v7 naming 'confusion' has to do with the fact that it isn't just a CPU, but rather a SoC (System on a Chip, IE, more than just a CPU)

  • Additional CPU / SoC Information (from App / Program on device, CPU-X (slightly different than CPU-Z, in that "Z" is for Android, "X" is for Windows): 1.0 GHz ARM v7 rev 3 (v71) on OMAP4 Piranha / Espresso Board
  • GPU: PowerVR SGX 540 (800px X 1280px or 1280px X 800px, depending on orientation)
  • RAM (Memory): 1 GB
  • Storage (Internal): 16 GB
  • Storage (Micro SD / Secure Digital Card): Up to 32 GB
  • OS (from LineageOS): Android 7.1.2 (Nougat)

Don't(s) - IE: Things You Should NOT Do

First some don't(s). Yes, it's as important what you don't do as what you do in this instance.

  • Do NOT install Google Play Services (causes performance issues, 100% CPU usage on the GT2-10.1)
  • Do NOT install Google Chrome (because it "requires" Google Play Services. And to be clear, the statement Google makes about "requiring" Google Play Services for Chrome to run is not accurate. They have chosen to make it such that Chrome will not run without Google Play Services, but could run without the service. Sort of like it does on Windows, Linux, etc.
  • Do NOT install Magisk (this may be different for other models and nothing against the Magisk software, it causes 100% CPU usage on the GT2-10.1
  • Do NOT install Firefox 92.x - 97.x (as of testing, 91.4 was the latest supported version that would function correctly on the GT2-10.1): https://en.wikipedia.org/wiki/Firefox_version_history

Do(s) - IE: Things You SHOULD Do

If you've got your device just the way you want it and are considering doing something like 'rooting it', consider doing a backukp using TWRP

Installation Instructions

It's all laid out here (so won't be repetative): https://wiki.lineageos.org/devices/espressowifi/install

Rooting

Didn't try it, but at least these guys have an "undo" that doesn't involve restoring a previous image: https://www.lineageosrom.com/2017/01/download-supersuzp-and-su-removalzip.html
