Vivo Y1s Custom Rom [portable] May 2026

Customizing the vivo Y1s (model V2026) is challenging because vivo devices are notoriously difficult to unlock. While there is no dedicated official custom ROM (like LineageOS) specifically built for this device, its MediaTek MT6765 (Helio P35) chipset allows for some advanced modifications using generic methods.  Feasibility of Custom ROMs 

Because the vivo Y1s launched with Android 10, it supports Project Treble. This means that instead of a device-specific custom ROM, you can theoretically install a Generic System Image (GSI). 

Availability: There are no widely recognized, stable "device-only" ROMs for the Y1s on major forums like XDA Developers.

Recovery: Official TWRP support is currently unavailable for this model. You may find "unofficial" or ported builds on community platforms like 4PDA, but these carry high risk of bricking your device.  The Unlocking Hurdle 

Before any ROM can be flashed, the bootloader must be unlocked. Vivo does not provide official unlock codes. 

UnlockTool: Technicians often use specialized PC software like UnlockTool to bypass the bootloader via the MTK Preloader or BROM mode.

Manual Method: While basic Android Developer Options (OEM Unlocking) can be toggled, they often don't truly unlock the bootloader on vivo without additional exploit tools.  Developer Resources & Tools

The story of the vivo Y1s and the world of custom ROMs is one of a budget-friendly device trying to find a second life beyond its original software.

Released as an entry-level smartphone, the vivo Y1s features a 6.22-inch display and modest internals, specifically 2GB or 3GB of RAM paired with 32GB of storage. While functional for everyday tasks, many users eventually seek custom ROMs to escape the limitations of the pre-installed Funtouch OS and improve performance. The Challenge of Customizing Vivo

The journey to a custom ROM for this specific device is often uphill. According to the official vivo Global FAQ, the company generally does not recommend flashing third-party ROMs or obtaining root permission, as it can compromise device security.

Unlike more "developer-friendly" brands, vivo makes it difficult to unlock the bootloader, which is the essential first step for any customization. The User Experience Journey 🚀 Project: Y1Surrection — Breathe New Life Into

For those brave enough to try, the "story" typically follows these milestones:

The Hardware Limits: Users realize that with only 2GB of RAM, the original OS can become sluggish over time.

Searching for "Clean" Software: Enthusiasts often look for lightweight alternatives like LineageOS or Pixel Experience to give the phone a faster, "Stock Android" feel.

The Technical Hurdles: Most "stories" involve a steep learning curve: Backing up all data. Attempting to bypass bootloader restrictions. Installing a custom recovery like TWRP. Wiping the old system and flashing the new ROM.

The Troubleshooting Arc: Many users find themselves needing to perform a hard reset when a flash goes wrong, using the device's Fastboot mode to recover.

Ultimately, while the vivo Y1s is a capable budget phone with a convenient fingerprint scanner, its custom ROM story is mostly written by advanced users willing to navigate strict security barriers to unlock more performance from their hardware.

Here’s interesting and useful content regarding custom ROMs for the Vivo Y1s (model: PD1731F) — a budget device with MediaTek MT6765 (Helio P35) and 2GB RAM.

Installation steps (typical, general)

1. Unlock bootloader (follow region-specific method).
2. Flash a compatible custom recovery (TWRP) via fastboot:
   • fastboot flash recovery twrp.img
3. Boot recovery, perform a full Nandroid backup (important fallback).
4. Factory reset / Wipe: Dalvik/ART cache, cache, data, and system (follow ROM instructions).
5. Flash ROM ZIP, then flash any required vendor/fix ZIPs.
6. Flash GApps (if ROM does not include Google services) and Magisk (optional).
7. Reboot system — first boot may take several minutes.

Why Install a Custom ROM on a Vivo Y1s?

By default, the Vivo Y1s runs on Funtouch OS 10 (based on Android 10). Vivo does not have a reputation for unlocking bootloaders or providing kernel source code quickly. Despite this, the developer community has found workarounds. Here is why you should consider it:

1. Vanilla Android Experience: Replace Funtouch OS with AOSP (Android Open Source Project) based ROMs like LineageOS or Pixel Experience. This removes bloatware and gives you a clean, Google-centric UI.
2. Performance Boost: Custom ROMs are lighter. On a device with only 2GB of RAM, removing background services from Vivo’s UI can free up significant memory, reducing lag and app crashes.
3. Extended Software Support: While Vivo abandoned the Y1s after Android 10, custom ROMs offer Android 11, 12, or even 13 (GSI builds), granting access to newer privacy features and security patches.
4. Customization: Root access (Magisk) combined with custom ROMs allows for themes, status bar tweaks, and kernel adjustments that are impossible on stock firmware.

What a custom ROM gives you

• Newer Android versions and security patches (when official updates are unavailable)
• Less bloatware and potentially faster, smoother performance
• Deeper customization (themes, gestures, status bar, navigation, animations)
• Root-friendly features and advanced power/profile controls
• Improved battery life via better kernel/CPU governors and wakelock fixes
• Optional privacy and permission-enhancing builds

3. Requirements Before Flashing

• Unlocked bootloader (if possible)
• Custom recovery (TWRP for MT6765 – ported from similar device like Redmi 9)
• Backup of stock ROM (especially persist, nvram, protect_f/protect_s)
• PC with SP Flash Tool + MTK USB drivers

Prerequisites: What You Need Before Flashing

Installing a custom ROM on a Vivo device is not as simple as on a Xiaomi or OnePlus. Vivo actively discourages bootloader unlocking. Proceed with extreme caution.

Requirements checklist:

• A Windows/Linux PC with ADB and Fastboot installed.
• Original Vivo USB cable.
• Backup of all data (Internal storage will be wiped).
• Unlocked Bootloader (This is the hardest step).
• Downloaded GSI image (e.g., LineageOS 19.1, crDroid, or Pixel Experience).
• Vivo Y1s Stock Firmware (to recover if things go wrong—find this on Vivo’s official support site or Russian forums like 4PDA).
