How to Update Oppo F1S to Android 13.0

Hey there, Oppo F1s fans! If you’re still holding onto that sleek little selfie machine from 2016, I’m guessing you’re someone who loves getting the most out of their tech.

The Oppo F1s launched with Android 5.1 Lollipop under ColorOS 3.0, and its official journey ended with Android 6.0 Marshmallow way back in 2017.

Fast forward to 2025, and Android 13.0 is the shiny new kid on the block—packed with modern features that could give your aging phone a serious upgrade. Official updates from Oppo? Nope, those dried up years ago. But don’t toss your F1s just yet—thanks to custom ROMs, you can breathe Android 13 life into it.

I’ve been elbow-deep in Android modding for years, flashing ROMs on everything from budget Xiaomis to vintage Oppos, and I’m here to walk you through this process.

We’ll explore why Android 13 is worth it, how your F1s can handle it, and the exact steps to make it happen. It’s a bit of a tech adventure—unlocking bootloaders, flashing recoveries—but I’ll keep it simple, fun, and doable, even if you’re new to this. Ready to turn your Oppo F1s into a 2025 contender? Let’s roll!

Why Bring Android 13.0 to Your Oppo F1s?

Let’s start with the “why.” The Oppo F1s was a mid-range star back in its day—5.5-inch screen, a killer 16MP front camera, and a decent MediaTek chip. But Android 5.1 or 6.0? That’s ancient history in 2025. Apps like WhatsApp and banking tools are phasing out support for anything below Android 9, and security risks loom large without updates.

Meanwhile, Android 13—released by Google in August 2022—brings a fresh vibe: Material You theming for personalized colors, better battery management, and tighter privacy controls (think per-app permissions and clipboard protection).

Why Android 13 specifically? It’s stable and optimized—by 2025, it’s powering over 30% of Android devices worldwide, per StatCounter’s 2024 data, and developers have ironed out its kinks.

For your F1s, it means a smoother, safer experience—imagine swiping through a modern UI, using the latest apps, and dodging those “your OS is too old” warnings.

Sure, it won’t turn your phone into a Snapdragon 8 Gen 4 beast, but it’ll keep it relevant for daily tasks like texting, browsing, and snapping selfies.

The hitch? Oppo waved goodbye to F1s updates long ago—Marshmallow was its swan song. So, we’re going off-road with a custom ROM—community-built software that swaps out ColorOS for a fresh Android 13 build. It’s a DIY upgrade, but oh-so-worth-it.

Can the Oppo F1s Run Android 13.0?

Before we dive into the how-to, let’s check the F1s’s chops. It’s got a MediaTek MT6750 octa-core processor (1.5GHz), 3GB or 4GB of RAM, and 32GB or 64GB of storage, with a Mali-T860 GPU under the hood.

That’s modest by 2025 standards—modern flagships flex 16GB RAM and 5nm chips—but custom ROMs are built to squeeze life out of older hardware. Android 13’s AOSP (Android Open Source Project) core can run on devices with as little as 2GB RAM, per Google’s lightweight guidelines, and the F1s clears that bar.

Will it be flawless? Not quite. The MT6750’s 32-bit architecture caps some 64-bit features, and you won’t be playing Genshin Impact at 60FPS. But for calls, social media, and light apps, it’s plenty capable.

I’ve seen XDA tinkerers push Android 12 onto similar-era phones (like the Redmi Note 4), and with 3-4GB RAM, the F1s holds its own. Battery life (3075mAh) might take a hit if the ROM isn’t tuned, but we’ll tweak that later. Bottom line: it’s doable, and the payoff’s a phone that feels 2025-ready.

How to Update Your Oppo F1s to Android 13.0

Here’s the main event—updating your Oppo F1s to Android 13.0 with a custom ROM. As of 2025, no official LineageOS 20 (Android 13) build exists for the F1s (model A1601), but unofficial AOSP or Lineage-based ROMs are out there, thanks to dedicated modders.

This process involves unlocking your bootloader, installing a custom recovery (TWRP), and flashing the ROM. Think of it like giving your phone a new operating system from scratch—exciting, right? Let’s break it down.

What You’ll Need

• Oppo F1s (A1601): Charged to 70% or more.
• A Computer: With ADB and Fastboot installed (Windows, Mac, or Linux).
• USB Cable: To connect your phone to the PC.
• Backup: This wipes your data—save photos, contacts, everything to an SD card or cloud.
• Time: 1-2 hours, depending on your setup.

Step 1: Unlock the Bootloader

Oppo’s bootloader unlocking can be a pain—they’re not big on custom mods—but it’s the first hurdle.

1. Enable Developer Options: Go to Settings > About Phone > tap “Build Number” 7 times.
2. Activate OEM Unlocking: Back to Settings > Developer Options > toggle “OEM Unlocking” on.
3. Boot to Fastboot: Power off, then hold Volume Down + Power until “Fastboot Mode” shows up.
4. Connect to PC: Plug in via USB, open a terminal (Command Prompt on Windows), and type fastboot devices to see your phone’s ID.
5. Unlock It: Type fastboot oem unlock. Use volume keys to select “Unlock” on your phone and press Power. It’ll wipe your data and reboot.

Note: Some F1s units need an unlock code from Oppo’s service tool—check XDA Forums for your region. If Fastboot balks, a 2025 workaround might be posted; search X for “Oppo F1s bootloader unlock 2025.”

Step 2: Install TWRP Recovery

TWRP is your flashing lifeline, but official support for the F1s faded years ago. Older builds still work, though.

1. Download TWRP: Hunt XDA or GitHub for “TWRP Oppo F1s A1601”—grab a MediaTek-compatible IMG like twrp-3.2.1-f1s.img (2018-era, but functional).
2. Flash It: In Fastboot, type fastboot flash recovery twrp-3.2.1-f1s.img, then fastboot boot twrp-3.2.1-f1s.img to test it.
3. Make It Stick: In TWRP, tap “Install,” select the IMG, choose “Recovery” as the partition, and swipe to flash. Reboot to recovery to confirm.

Step 3: Flash the Android 13 ROM

Now, the fun part—finding and installing Android 13.

1. Find a ROM: Scour XDA Forums, Telegram (try “Oppo F1s Custom ROMs”), or X posts for “Oppo F1s Android 13 ROM 2025.” Look for an AOSP or LineageOS 20 port—something like lineage-20.0-20250310-UNOFFICIAL-f1s.zip.
2. Grab GApps (Optional): Want Google Play? Download Open GApps Pico (Android 13, ARM 32-bit) from opengapps.org—keeps it light.
3. Transfer Files: Copy the ROM ZIP and GApps ZIP to your phone’s SD card or internal storage via USB.
4. Flash Away: Boot to TWRP (Volume Up + Power), tap “Wipe” > “Advanced Wipe” > check Dalvik, Cache, Data, System > swipe to wipe. Then “Install,” pick the ROM ZIP, swipe to flash. Add GApps if desired, then reboot.

Step 4: Boot and Fine-Tune

First boot takes 5-10 minutes—don’t freak if it lingers on the logo. You’ll land on Android 13’s setup screen—set your language, Wi-Fi, and account. If it’s sluggish, tweak Developer Options (Settings > System > Developer Options): lower animation scale to 0.5x or limit background processes to 2.

Real-World Example

Last year, I flashed an Android 12 ROM on an F1s for a friend—took an hour, and it ran WhatsApp, YouTube, and banking apps like a champ. In 2025, an X user (@ModMasterPH) shared their Android 13 success on an F1s—smooth for daily use, though Bluetooth was spotty. Your mileage might mirror that—solid, with quirks.

What You’ll Get (and What You Won’t)

Running Android 13 on your F1s is a game-changer:

• Fresh UI: Material You colors, quick settings tweaks, and modern navigation.
• App Compatibility: Most 2025 apps should work—no more “OS too old” errors.
• Privacy Boost: Granular permissions and lockscreen tweaks keep you secure.

But it’s not a flagship reboot. The camera might lose some Oppo polish—custom ROMs rarely nail stock drivers. Heavy apps could lag, and battery life might dip unless the ROM’s optimized. Still, for a nine-year-old phone, it’s a massive leap from Marshmallow.

Risks and Realities

This isn’t a plug-and-play update—here’s the fine print:

• Data Wipe: Unlocking and flashing erase everything—back up first.
• Brick Risk: A bad flash or locked bootloader could leave your phone stuck. Stock firmware (search “Oppo F1s A1601 stock ROM” on getdroidtips.com) can revive it, but it’s a hassle.
• ROM Bugs: Unofficial builds might glitch—Wi-Fi, camera, or sensors could misbehave. Check user feedback before flashing.
• No Oppo Help: Official support’s gone—you’re leaning on the community.

Tested a dud ROM? Flash another or roll back to stock. I’ve rescued bricked phones before—it’s fixable with patience.

Why Do This in 2025?

Why now? In 2025, older devices are having a moment—sustainability’s hot, and folks are stretching their tech’s lifespan. With Windows 10’s end in October, the vibe’s all about keeping what works.

Android 13’s maturity (over two years old) means stable ROMs, and the F1s’s selfie legacy deserves a modern stage. Plus, 65% of Android users value customization, per a 2024 Android Central poll—this is peak DIY phone fun.
