The 2015 Huawei Y6 and Honor 4A series (models SCL‑L01/L03/L04/L21/L32, SCL‑U31, SCC‑U21, SCL‑AL00/TL00/TL00H/TL10H) use a 5.0‑inch 720×1280 IPS display, Snapdragon 210 MSM8909, 1–2 GB RAM, 8 GB storage and a 2200 mAh battery, shipping with Android 5.1 Lollipop and EMUI 3.1.
With age these devices often suffer from bootloops, stuck‑on‑logo, failed EMUI updates and system corruption; the SCL/SCC and Honor 4A firmwares and board packages below allow technicians to restore stock Lollipop EMUI 3.1, unbrick dead boards (Qualcomm 9008) and fix many software‑side faults across Europe, Latin America, China and other regions.

Flashing Requirements
- Windows PC or laptop with Huawei USB drivers and, for board/QPST/9008 images, Qualcomm tools such as QPST/QFIL or Huawei Smartphone Multi Download.
- A reliable microUSB cable and, for Dload firmwares, a FAT32‑formatted microSD card (8–32 GB) containing the de>dload folder and de>UPDATE.APP file.
- Battery at 60 % or higher before flashing to avoid shutdown mid‑update, which can further corrupt partitions and worsen bootloops.
- Full backup of user data (contacts, photos, apps) whenever the phone still boots, as most Dload and board‑software flashes will erase internal storage.
- Strict match between device model and region code (for example SCL‑L21 C432 vs C900, SCL‑L03 C469, SCL‑AL00 C00, SCL‑TL00H/TL10H C00/C01) to keep network bands working and to avoid “software install failed” in EMUI recovery.
How to Flash the Firmware
- Download the exact firmware for your variant (for example SCL‑L21 C432B150, SCL‑L03 C469B130, SCL‑U31 C900B130 or SCL‑TL00H C00B251) and extract it until you see a de>dload folder or an de>UPDATE.APP file.
- For Dload: copy the entire de>dload folder to the root of a FAT32 microSD card, insert it into the powered‑off phone, then hold Volume Up + Volume Down + Power together until the EMUI update screen appears and the progress bar starts.
- Let the installation reach 100 % without removing the battery, USB cable or SD card; the phone will reboot itself into the restored system when done.
- For board / QPST 9008 packages (for example SCL‑L21 C900B050 Board, SCL‑L01 C900B057 Board, SCL‑U31 C900B130.9008): place the device into Qualcomm 9008/EDL mode (often via key combo or test‑point), then use QFIL/QPST to load the rawprogram/XML and flash all required partitions.
- After a successful flash, allow extra time for the first boot while Android and EMUI rebuild caches, then verify in Settings > About phone that the model, CUST and build match the intended firmware.
For step‑by‑step screenshots of the SD‑card Dload process you can follow our Huawei Y6 EMUI 3.1 flashing tutorial, and for Qualcomm 9008 repairs consult detailed QFIL/QPST guides specifically referencing Snapdragon 210 (MSM8909) Huawei Y6 / Honor 4A devices.
❗ Disclaimer: All Huawei Y6 / Honor 4A firmwares, board software and dumps listed here are used entirely at your own risk. Incorrect flashing can cause data loss, IMEI/network issues, bootloops or permanent hard bricks. If in doubt, seek help from an experienced technician or dedicated Y6 / Honor 4A forums before proceeding.
Frequently Asked Questions (FAQs)
What Y6 / Honor 4A problems can these firmwares fix?
Correct stock firmware can resolve most software‑side issues such as devices stuck on the logo, bootloops, failed OTA updates and severe lag caused by corrupted system or userdata partitions.
Can I cross‑flash SCL-L21 firmware onto SCL-U31 or Honor 4A models?
No, cross‑flashing between SCL‑Lxx, SCL‑U31, SCC‑Uxx and Honor 4A SCL‑AL00/TL00/TL00H/TL10H variants or mismatched CUST codes is very risky and can permanently disable network or brick the device.
Do these updates change Android or EMUI versions?
All listed packages remain on Android 5.1 / 5.1.1 and EMUI 3.1; they mainly provide regional customization, bug fixes and clean system images rather than major Android upgrades.
Will flashing these files erase my data?
Yes, Dload and 9008/board flashes usually perform a factory reset and can re‑partition storage, so always back up your data first if the phone still boots into Android or custom recovery.
What if the phone is still dead after 9008 / board flashing?
If a correct board/9008 flash completes but the device remains dead or unstable, the fault may be hardware‑related (for example damaged eMMC, power IC or board corrosion) and will require hardware repair instead of further firmware attempts.
