Crucial Warning: These packages are only for the Huawei CAG family, and even inside that family you still must match the exact device label such as CAG-L02, CAG-L03, CAG-L22, or CAG-L23 before flashing. A later CAG-L22 package like C461B152 is not a safe substitute for a CAG-L23 C469 device, and a board package labeled Board_Software_General should not be treated like a routine end-user update. This device class runs on very modest Android Go hardware, so a wrong firmware can quickly leave the phone stuck at logo, without network, or unable to finish setup after boot.

CAG-L22_CairoGO-L22C461B152_Firmware_8.1.0_r1_05015ANC.rar
Highest build number in the L22 set; note that C461 and C185 are different branch tracks, not sequential versions of the same branch.

Standard local-update archive for the C185 branch.
⬇️ Download via Google DriveHuawei_Y3_2018_CAG-L22_MT6737M_L22C185B144_08212018.zip
This appears to be the same core C185B144 package with a date-stamped filename. Treat it as a duplicate mirror unless extraction shows different contents.

Fuller service-style package for the C469 branch, larger than the B126 archives below.

Standard-format local-update package for the C469 branch, as opposed to the RAR service package above.
⬇️ Download via Google DriveHuawei_Y5_Lite_2018_CAG-L23_MT6737M_L23C469B126.zip
Likely a duplicate of the dated L23C469B126 archive above. Keep it as an alternate source, not as a separate firmware branch.

One of the oldest entries in this set.
⬇️ Download via Google DriveHuawei_Y3_2018_CAG-L02_CairoGO-L22-B048_MT6737M_Board_Software_General_Android_8.1_05022KSE.zip
The "Board Software General" label suggests a service-oriented package rather than a routine consumer update. Use it carefully and only when a normal package is unavailable or when the phone needs low-level board recovery.

- Confirm the exact CAG model and branch before choosing a file
- Extract the ZIP or RAR fully and check for Huawei's UPDATE.APP structure
- Create a dload folder on local storage or microSD and place the extracted files there
- Start the stock update through the Huawei dload route without interrupting power
- Verify build number, SIM detection, and Wi-Fi behavior before restoring data
Expand preparation checklist for Huawei Y3 2018 / Y5 Lite 2018
- Read the exact model from the phone label or recovery screen first and do not guess between CAG-L02, CAG-L03, CAG-L22, and CAG-L23.
- Write down your current build string if the phone still boots, especially the branch code like C185, C461, C469, or C25. That will tell you whether you are restoring the same software family or jumping to a different one.
- Extract the archive fully before choosing any method. If the package contains an UPDATE.APP file, it belongs to Huawei's dload-style local update workflow.
- Back up any reachable data before flashing, because a clean stock restore can wipe apps, settings, and user files.
- Charge the battery properly and avoid damaged SD cards or unstable internal storage, since low-end Android Go devices are less forgiving when an update is interrupted.
- Prefer the normal consumer package first, and keep the "Board Software General" files for harder recovery cases where a standard archive is not enough.
Compatibility & Bootloader Notes
For normal stock recovery on this device class, the practical issue is exact model-and-branch matching through the dload workflow rather than bootloader unlocking or fastboot experimentation. If the extracted package contains an UPDATE.APP structure, it belongs to Huawei's local-update route; "Board Software General" archives are aimed at deeper service-level repair instead of routine reinstalling.

Frequently Asked Questions
Because this archive set appears to mix retail naming across regional branches, the safer compatibility rule is to follow the printed CAG-* model number and branch code instead of trusting the product name in the filename alone. That matters more than branding when you are actually flashing the phone.
Not automatically. A higher build can still be the wrong software family if the phone originally belongs to a different branch, so the first priority is branch match, not just the biggest number.
The smaller archives look like standard local-update packages, while the larger RAR files look more like fuller service packages with extra components. If your goal is a simple stock reinstall, the smaller exact-match package may be easier, but for deeper recovery the larger archive can be more useful after extraction.
Usually no. The "Board Software General" label suggests a more technical recovery package, so it makes more sense for tougher repair situations than for routine reinstallation.
No. Shared chipset and similar build numbers do not make two Huawei variants interchangeable. The safer rule is exact model match first, even on low-end devices that look closely related.
The Y3 (2018) class is built around 1GB RAM, 8GB storage, and the MT6737M chipset, so it has very little headroom for corrupted cache, failed updates, or bloated app data. That is why a clean stock firmware reinstall often helps more on this model class than trying to layer fixes on top of a broken system.
For normal stock Huawei recovery packages, the standard route is Huawei's own local update / dload workflow rather than fastboot unlocking. If your extracted package contains Huawei update files, start there before considering any lower-level tool.
