To install a custom ROM on the SM-P585Y, you must follow these standard steps:
For the Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y), custom ROMs are the primary way to bypass the official "end-of-life" software (Android 8.1) and run modern apps in 2026. Performance & Stability Review
System Speed: Users report significant performance gains compared to the bloated stock Samsung Experience. Modern lightweight ROMs like LineageOS resolve multitasking issues where background apps would previously close prematurely.
App Compatibility: Installing Android 13 or 14-based ROMs allows the tablet to run the latest versions of apps from the Google Play Store, which are otherwise restricted on the tablet's native Android 8.
Battery Life: Optimized custom kernels often included in these ROMs provide better idle battery drain and thermal management compared to the aging official firmware.
S-Pen Functionality: While basic S-Pen input (drawing/writing) works on most AOSP-based ROMs, specialized Samsung-specific features like "Air Command" are typically lost. You may need third-party apps to replicate the advanced pen menus. Top Custom ROM Options (2026)
The development for this device (codename: gtanotexllte) is often bundled with its Wi-Fi sibling (gtanotexlwifi) and the non-S-Pen variant (gtaxllte).
LineageOS 20 (Android 13): Currently the most stable and popular choice. It provides a "near-vanilla" Android experience that is highly responsive on the tablet’s Exynos 7870 chipset.
LineageOS 19.1 (Android 12): A rock-solid alternative if you encounter bugs on newer versions. It is praised for fixing the multitasking bugs found in earlier unofficial builds.
crDroid (Android 14/GSI): For users wanting the absolute latest Android version, GSI (Generic System Image) builds of crDroid offer deep customization, though they may require more manual troubleshooting. Critical Installation Notes
Custom Recovery: You must first install TWRP for SM-P585Y to flash any custom ROM.
Google Apps (GApps): Most ROMs come "vanilla." You need to flash a GApps package (like NikGApps or MindTheGapps) separately to get the Play Store.
Bootloader: Ensure your bootloader is unlocked. Attempts to flash on a locked bootloader will result in a "Secure Check Fail" error.

The stock ROM comes with dozens of pre-installed apps (bloatware) that you cannot uninstall without rooting. Custom ROMs come with only the essential Google apps (or none at all), freeing up storage and RAM.

For the Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y), moving to a custom ROM can breathe new life into a device that officially stopped at Android 8.1 Oreo. Available Custom ROMs
While this specific LTE variant (codename gtanotexllte) has slightly less traffic than its Wi-Fi counterpart (SM-P580), there are active community projects: sm-p585y custom rom
LineageOS: Unofficial builds of LineageOS 19.1 (Android 12) and LineageOS 20 (Android 13) have been developed for the gtanotexllte/gtanotexlwifi series. These provide a clean, "stock-like" experience and better performance than Samsung’s original One UI.
e/OS: Unofficial builds based on Android 12 (S) are also available, focusing on privacy and de-Googling.
GSI (Generic System Images): As a last resort, some users have successfully flashed GSIs like crDroid (Android 14) using TWRP, though stability can vary greatly on older hardware. Key Considerations Before Flashing
S Pen Functionality: Most AOSP-based ROMs (like LineageOS) support basic S Pen input, but you will lose Samsung-specific S Pen features like "Air Command" and specialized note-taking apps unless you use third-party alternatives from the Play Store.
Knox & Security: Unlocking the bootloader permanently trips Knox. This disables features like Samsung Pay and Secure Folder forever.
VoLTE Issues: A common bug with Exynos-based Samsung custom ROMs is the lack of VoLTE support. This means you may be able to use LTE for data, but traditional voice calls might not work if your carrier requires VoLTE. Quick Setup Steps
The Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y) is a legacy device officially capped at Android 8.0 Oreo. Custom ROMs are the primary method for updating this tablet to modern versions like Android 10, 11, or even Android 13/14 via Generic System Images (GSIs). Current Custom ROM Landscape
Recent community developments have brought the SM-P585Y (codenamed gtanotexllte) back to life with various builds:
LineageOS 20 (Android 13): This is one of the most recent stable paths for "reviving" the tablet, allowing for the installation of modern apps from the Play Store.
e/OS (Android 13/T): Unofficial builds for the SM-P585 have been released by community developers like ronnz98, providing a de-Googled, privacy-focused experience.
Android 10 (LineageOS 17.1): A common, stable choice for users who want a balance of performance and compatibility.
Generic System Images (GSI): Because this tablet supports Project Treble through certain custom recoveries, advanced users have successfully flashed Android 14 GSI builds (e.g., crDroid). Installation Prerequisites Before flashing, you must prepare the following tools:
Custom Recovery: TWRP (Team Win Recovery Project) is required to flash the ROM files.
Odin: A PC-based tool used to flash the TWRP recovery image onto the tablet.
Drivers: Ensure Samsung USB Drivers are installed on your computer. Core Installation Procedure
Unlock Bootloader: Enable "Developer Options" by tapping Build Number 7 times, then toggle "OEM Unlocking".
Flash Recovery: Put the tablet in "Download Mode" and use Odin to flash the .tar TWRP file to the AP slot.
Wipe System: Boot into TWRP, go to Wipe > Advanced Wipe, and select Dalvik/ART Cache, System, Data, and Cache. Flash ROM & GApps:
Transfer the ROM .zip and GApps (Google Apps) package to the internal storage or SD card.
In TWRP, select Install, pick the ROM file, and then the GApps file.
Reboot: Perform a factory reset if you encounter a boot loop. Known Issues & Limitations
S Pen Support: While the S Pen generally works for basic navigation on custom ROMs, advanced features like "Air Command" or pressure-sensitive Samsung apps are usually lost unless using a TouchWiz-based custom ROM.
Stability: Some users report issues with "Doze mode" (battery saving) or specialized launchers having minor bugs on newer Android 13 builds.
GApps Bug: On some SM-P585 builds, you may need to flash the ROM, reboot to recovery again, and then flash GApps to avoid installation errors.
The Samsung Galaxy Tab A 10.1 with S Pen (SM-P585Y), released in late 2016, remains a capable device for note-taking and media consumption. However, as official software support has ended, installing a custom ROM is the best way to upgrade to modern Android versions like Android 13 or 14. Why Install a Custom ROM on SM-P585Y? For the Samsung Galaxy Tab A 10
Modern Software: Transition from outdated Android 8.1 Oreo to newer versions like LineageOS 20 (Android 13).
Performance Boost: Custom ROMs often remove Samsung's "bloatware," leading to smoother UI animations and better battery management.
Security: Gain access to updated security patches that the official firmware no longer provides. Top Custom ROM Options
LineageOS (Unofficial): The most popular choice for the SM-P58x series. Unofficial builds of LineageOS 20 and 21 provide a clean, near-stock Android experience while maintaining S Pen functionality.
/e/OS: A privacy-focused ROM that removes Google services. Recent unofficial builds for the "gtanotexllte" (SM-P585) codename are available for those seeking a "de-Googled" experience.
Project Elixir / DotOS: Occasionally ported by community developers on XDA Forums, these ROMs offer deep visual customization. Essential Prerequisites Before flashing, you must prepare your device and PC:
The year was 2024, and the Samsung Galaxy Tab A 10.1 (2016) with S Pen, model number SM-P585Y, was not aging gracefully.
For its owner, Elias, the tablet had become a test of patience. Once a capable digital canvas, it now wheezed under the weight of modern apps. The S Pen, still physically perfect, felt sluggish on the screen because the processor was throttling, trying to manage the bloated factory software. The final straw came when Elias tried to open a PDF for a work meeting, and the tablet simply stared back at him for forty-five seconds before crashing to the home screen.
"Junk," Elias muttered, tossing it onto the couch. He reached for his laptop to order a new iPad.
But then, he paused. He remembered the old mantra of the tech forums: Hardware doesn’t die; software kills it.
He picked up the tablet again. The screen was still beautiful. The Wacom digitizer layer for the S Pen was a feature you couldn't find on cheap tablets anymore. It was too good to throw away.
Elias opened his laptop and typed the incantation: sm-p585y custom rom.
The search results were a digital wasteland. "Bootloop," "Bricked," "Error 7." The SM-P585Y was the weird Australian/New Zealand variant. It wasn't the popular LTE version sold in Europe; it was specific, finicky, and largely abandoned by the developer community years ago.
After an hour of digging through the archives of XDA Developers, he found a single thread from three years ago. The developer, a user named PhantomCoder, had ported a version of LineageOS (Android 11) specifically for this obscure model. The thread was full of people thanking him for bringing the dead back to life.
"Let's do it," Elias whispered.
The process was a high-wire act. He installed Odin, the Samsung flashing tool, which looked like a piece of software from the Windows 95 era. He hunted down the exact TWRP recovery image—a custom boot environment required to install the new software. He had to uncheck a box labeled "Flash Lock" that forum veterans warned would permanently brick the device if touched.
He connected the tablet to the PC. The Odin interface turned blue. Connected.
He hit start. A green progress bar crawled across the screen. The tablet rebooted into a black screen with white text.
Success.
But they weren't done. He now had the recovery tool, but no operating system. He copied the LineageOS ZIP file and a separate ZIP for Google Apps onto an SD card—since the internal storage was currently a blank slate.
He booted into TWRP. The touch interface was jittery, but functional. He selected Wipe, then Install. He navigated to the SD card.
The installation bar moved. "Updating system files..." "Installing boot image..."
The tablet rebooted. The screen went black. Elias waited. One minute. Two minutes. The fear of the "bootloop" crept in. Had he just turned the device into a paperweight?
Then, the screen flickered.
A bright, clean boot animation appeared. It wasn't the loud, neon Samsung logo. It was the sleek, cyan circle of LineageOS. Prerequisites (The Tools You Need): Before you search
The lock screen appeared. It was fast. Incredibly fast. The animations were snappy, devoid of the heavy TouchWiz lag that had plagued the device for years.
Elias tapped the screen, pulled the S Pen from its slot, and opened a note-taking app. The lines appeared on the screen instantly—zero latency. He opened Chrome; it loaded in a second. He opened YouTube; it played smoothly without stuttering.
