This firmware collection covers the Huawei CAG family built around the CairoGO line, with CAG-L02 and CAG-L22 sold as Huawei Y3 (2018), while CAG-L03 and CAG-L23 appear in Latin American listings as Huawei Y5 Lite (2018).
The shared hardware base across these supplied variants is the MediaTek MT6737 or MT6737M family with Android 8.1 Oreo Go Edition, which makes exact regional and model matching more important than the marketing name alone.
These stock packages are mainly useful for software recovery, restoring the correct branch after a wrong flash, or returning the phone to stock software after failed modification work.
The package set includes both standard firmware archives and smaller files explicitly labeled Board Software, so the correct installation path depends on the extracted package contents rather than one single assumed tool for every file.

⚠️ Flashing Risks & Disclaimer
The main risk on this CairoGO family is mixing CAG-L02 or CAG-L22 Y3 (2018) packages with CAG-L03 or CAG-L23 Y5 Lite (2018) regional branches, or treating a Board Software archive as if it were the same kind of package as a full stock firmware file.
This package remains the property of its respective owner and is referenced only for restore or service use on legally owned Huawei devices.

Flashing Requirements
- Match the phone to the correct CAG branch first, because CAG-L02 and CAG-L22 align with Huawei Y3 (2018), while CAG-L03 and CAG-L23 appear as Huawei Y5 Lite (2018) in Latin American references.
- Check the extracted archive for a
dloadfolder,UPDATE.APP, or other Huawei stock update structure before selecting a guide, because this page mixes standard firmware archives with Board Software service packages. - Treat Board Software packages as service archives and not as normal user-side local updates, because the filenames identify them separately from standard stock firmware files.
- Back up important data before flashing, because full restore work and service packages should be treated as wipe-prone.
- Verify branch codes such as C461, C185, C469, and C25 before flashing, because they represent different software customizations within the same CAG hardware family.
How to Flash the Firmware
- Choose the exact package that matches the phone’s model and branch, starting with CAG-L02 or CAG-L22 for Y3 (2018) and CAG-L03 or CAG-L23 for Y5 Lite (2018) regional variants.
- Extract the archive before flashing anything, because this collection includes both full firmware files and Board Software packages that should not be handled as interchangeable archives.
- If the extracted package contains Huawei local-update contents such as
dloadorUPDATE.APP, use the Huawei stock update path that matches that structure. - If the extracted package is labeled Board Software and exposes service-style contents instead, use a service-oriented flashing path rather than a normal end-user update route.
- After installation, allow extra time for the first boot, then troubleshoot further only if the phone remains stuck in a bootloop or cannot finish setup after a long restart window.
Possible guide options for this mixed CAG collection depend on the extracted package contents rather than one single universal method.
- Huawei dload / eRecovery guide for full stock packages that contain a
dloadfolder orUPDATE.APP. - OTA / sideload / local update guide for stock update archives meant for Huawei local update handling.
- SP Flash Tool guide only when the extracted archive clearly exposes a scatter-based MediaTek service package, because the filenames alone do not prove that every file on this page uses that workflow.
Frequently Asked Questions (FAQs)
Is CAG-L22 the same device as CAG-L23?
No. CAG-L22 is part of the Y3 (2018) side of the CAG family, while CAG-L23 appears in Latin American references as Y5 Lite (2018), even though both stay within the same MT6737-series hardware family.
Can a CAG-L02 board software package be flashed on CAG-L03?
That should not be assumed safe, because Board Software archives are service packages and the supplied filenames already separate CAG-L02 and CAG-L03 into different branch-specific files.
Why do some filenames say Y3 2018 while others say Y5 Lite 2018?
The CAG platform appears under Y3 (2018) naming for some variants and Y5 Lite (2018) naming for some Latin American variants, which is why the model code matters more than the marketing label alone.
Is MT6737M verified for this family?
Yes. The CAG Y3 (2018) family is documented on MT6737M, while the Y5 Lite (2018) CAG-L03 and CAG-L23 references also stay within the MT6737 family, so this collection is safest to describe as an MT6737-series branch.
Should every file here be flashed with the same tool?
No. The page mixes standard firmware and Board Software packages, so the extracted package contents should decide whether the correct path is dload, local update, or a service workflow.
