Vivo Y1s Custom Rom
is a budget-oriented smartphone powered by the MediaTek Helio P35 (MT6765) chipset. While it runs on Vivo's proprietary Funtouch OS
Prerequisites
- Charge battery to ≥60%.
- Windows PC or Linux machine with ADB & Fastboot tools installed.
- USB cable and drivers for Vivo Y1s installed on PC.
- Unlockable bootloader (some Vivo devices require approval).
- Download correct ROM ZIP, compatible GApps (if ROM is AOSP without Google apps), Magisk (if you want root), and device-specific firmware/firmware patches if required.
- Custom recovery ZIP (TWRP) or patched stock recovery image for your device.
- fastboot flash recovery twrp.img
Step 3: Wipe Partitions
- In TWRP, go to Wipe → Advanced Wipe.
- Select: Dalvik / ART Cache, System, Data, Cache.
- Do NOT wipe Internal Storage if the ROM is on your phone.
MediaTek VBV/DM-Verity: Modern MediaTek devices like the Y1s have strict verified boot protocols. Modifying the system partition often results in a "Boot Loop" or "System destroyed" error unless the vbmeta is correctly patched. vivo y1s custom rom
Keeping ROMs secure and updated
- Use ROMs from reputable developers and active threads (maintainers with regular updates).
- Read changelogs and user reports before upgrading.
- Avoid unofficial “random” builds without user feedback or source code availability.
- Check permissions and audits for bundled apps — uninstall or disable anything suspicious.
The GApps Irony
Even if you somehow unlocked the phone, the Y1S has only 2GB of RAM and 32GB of storage (eMMC 5.1). Funtouch OS is heavy, but custom ROMs like LineageOS (lightweight) would actually run better. The irony: The phone is perfect for a debloated custom ROM, yet Vivo's ecosystem makes it impossible. is a budget-oriented smartphone powered by the MediaTek
