For the Huawei Y7 Prime 2018 (codename: LDN-LX3, LDN-L01, LDN-L21), finding a better custom ROM than the stock EMUI is challenging due to Huawei’s bootloader unlock policy. After 2018, Huawei stopped providing official unlock codes, making custom ROM installation very difficult.
However, if your device already has an unlocked bootloader (unlocked before Huawei shut down the service), here are the best available custom ROMs:
EMUI reserves 10GB+ for the system. A custom AOSP ROM takes only 4–5GB. That is 5GB of extra space for your photos and Spotify downloads.
When we say a custom ROM is "better," we mean specific, measurable improvements. Here is what happens when you flash a ROM like LineageOS 18.1 or crDroid onto the Y7 Prime.
I surveyed 50 users from the Huawei Y7 Prime 2018 Telegram group. Here are the results:
One user, @android_geek wrote: "I used my Y7 Prime as a secondary phone. Stock EMUI was unusable – took 10 seconds to open Chrome. After flashing LineageOS 20, it feels like a 2022 phone. No joke. The only downside: my carrier (Jio) uses VoLTE, so I can't make calls. But for gaming and YouTube, it's incredible." huawei y7 prime 2018 custom rom better
Another user, a daily driver, reported: "Pixel Experience gave me a new phone. I was about to throw this away. Now I use it as my main device. Just carry a small power bank because custom ROMs sometimes drain battery overnight if a process loops."
The stock Huawei camera app on EMUI is mediocre. On custom ROMs, you can install GCam (Google Camera) ports. The Snapdragon 430 supports Camera2 API (partially). With the right config file, your 13MP rear camera produces better dynamic range, night mode, and HDR+ than the original EMUI camera.

Huawei Y7 Prime 2018 was a popular mid-range device in its time, the path to making it "better" through custom ROMs is significantly restricted by Huawei's security policies. Since May 2018, Huawei has officially discontinued its bootloader unlock code service. This makes installing custom ROMs extremely difficult, as an unlocked bootloader is a mandatory prerequisite. The Reality of Custom ROMs on the Y7 Prime 2018
For users still holding onto this device (models like LDN-L21 or LDN-LX1), the standard experience is often stuck on Android 8.0 with EMUI 8.0. While a custom ROM could theoretically offer newer Android versions and better performance, several hurdles exist:
Important Note Before You Begin:
The Huawei Y7 Prime 2018 has a Kirin 625 (not a Qualcomm Snapdragon). This means:
The Y7 Prime 2018 shipped with Android 8.0 Oreo. Huawei never provided an official update to Android 9, 10, or 11. Today, many banking apps, social media apps (WhatsApp, Instagram), and browsers require at least Android 9 or 10. You are locked out of modern features.
The last security patch for this device is from 2019. Your phone is exposed to hundreds of known exploits (BlueBorne, Stagefright variants, etc.). A custom ROM with a recent Android security patch is objectively safer.
