Because GSIs are generic, VoLTE or specific network bands sometimes require manual configuration. Check the "Phh-Treble Settings" menu (usually found under Settings > System) to toggle specific MediaTek compatibility fixes.
Android 10 or 11-based GSIs (LineageOS 17.1 or 18.1) offer the best stability and performance balance for the Helio A22 processor. 2. Pixel Experience (GSI)
Given the high risk and low probability of successfully installing a custom ROM, it is wise to consider official and safer alternatives.
Because Huawei closed its official bootloader unlocking portal, flashing custom ROMs on this specific MediaTek device relies entirely on and special bypass tools like the SP Flash Tool . Below is a comprehensive breakdown of the top custom ROM options, prerequisites, and a step-by-step flashing guide. Top Custom ROM Options for Huawei Y5 2019 custom rom for huawei y5 2019 top
The primary motivation for users seeking a Custom ROM is usually . Custom ROMs, particularly those based on the Android Open Source Project (AOSP) or LineageOS, strip away the manufacturer skins and carrier apps that clog the system. On a device with limited storage (16GB internal) and RAM, this "lightness" is not just a preference—it is a necessity for survival.
Huawei officially stopped providing bootloader unlock codes in 2018. To install any custom ROM, your device's bootloader must be unlocked. For the Huawei Y5 2019 (AMN-LX1, AMN-LX2, AMN-LX3, etc.), you cannot unlock the bootloader through official software. Instead, you must rely on third-party hardware exploits or paid services (such as DC-Unlocker or Chimera Tool) that exploit the MediaTek (MTK) boot ROM vulnerability. Do not attempt to flash a ROM unless you have successfully unlocked your bootloader first. Project Treble and GSIs
The core specifications are as follows:
This is the most challenging step for Huawei devices. Huawei stopped providing official bootloader unlock codes years ago. You will need to use third-party hardware testpoint methods or software tools (such as PotatoNV or paid services like DC-Unlocker) compatible with the MediaTek MT6761 chipset to unlock the bootloader.
For users who want to customize every single aspect of their status bar, lock screen, and themes.

The single biggest barrier to installing any custom software on this phone is Huawei’s decision to stop providing official bootloader unlock codes. As noted by XDA Developers, “Huawei has stopped providing official bootloader unlock codes for its devices,” meaning the bootloaders of their devices cannot be unlocked via official means. Without an unlocked bootloader, you cannot flash custom recoveries like TWRP or install unsigned system images.
Do flash TWRP files from unknown sources. The safest approach is to skip TWRP entirely and rely on fastboot flashing for GSIs. If you are determined to find a working TWRP, the only trustworthy places to look are the Huaify 5 (2019) sections on XDA‑Developers or the official TWRP website (which currently does not list this device).
