Huawei Y3II (LUA Series) Official Firmware

Huawei Y3II (LUA Series) Official Firmware, Unbrick, and Flash Guide (L01, L02, L03, L13, L21, L22, L23, U02, U22, U23)

Is your Huawei Y3II frozen, stuck in bootloop, showing “Chip Damaged,” or failing update after SD/FlashTool/FRP? This guide provides a unique, model-grouped and region-correct firmware collection for all MT6582/MT6735M (LUA-L/U series): Kenya, India, Russia, Mexico, EU, Mediatek (not Qualcomm) boards. With clear warnings for “dead/brick” cases and IMEI risks, this covers both SD_Update and SP Flash Tool, sorted for safe, real-world repair.

⚠️

CRUCIAL WARNING:

  • MT6582 builds (U22/U02) ≠ MT6735M builds (L01/L02/L03/L13/L21/L22/L23): do not swap firmware!
  • SD_Update zips are safe for recovery/OTA; SP Flash Tool “scatter” ROMs erase everything & will wipe IMEI if preloader unchecked or wrong region/model installed.
  • Kenya Safaricom, India, Russia, Mexico & EU all use unique modem/baseband—cross-flashing can break SIM, network, display, or “chip damaged” errors.
  • Dead boot? Only use board/unbrick files built for your hardware revision—most U22 dead boot is from MT6582 tool flashed on a newer HW board.

Before You Begin ⚙️

  • 💾 Backup IMEI/NVRAM if possible before scatter flash. Wrong region can erase phone identity.
  • 🔋 Charge to 60%+ before flashing.
  • 🚩 SP Flash Tool = full wipe. SD Update is safer if phone boots recovery. Never mix U22/U02 and L22/L02 boards.
  • 🪛 “Dead boot” is almost always caused by wrong scatter or board mismatch. Use board/vendor-correct firmware only. Consult technician if unsure.

📱 Quick Model-Safe Flashing Guide

  1. Verify your model (Settings > About or under battery/SIM tray) and region code.
  2. Download matching firmware above.
  3. SP Flash Tool: Extract, open scatter file, uncheck preloader unless dead, select firmware upgrade or download only.
  4. SD Update: Copy update.zip to SD, boot recovery (Vol Up + Power), select “apply update from SD”, wait and reboot.
  5. If phone is dead after flash, recheck board number and try board-correct “dead boot” package or consult service.

Frequently Asked Questions (FAQs)

Q1: Why is my Y3II stuck with “chip damaged” after flashing?
This means the wrong SoC or board scatter was used (MT6582 vs MT6735M or different custom variant). Only use model-correct files!
Q2: Will I lose IMEI?
Yes if flashing with SPFT and preloader/region mismatch. Always backup NVRAM and avoid random “upgrades” across model codes; use SD update if possible.
Q3: Russian, Swiss, Kenya, India, Mexico: why so many variants?
Every carrier, region, and SoC combo has custom modem and partition—downloading only by baseband/board ensures no SIM/network break after repair.
Q4: Is dead boot permanent?
Rarely—usually fixed by flashing exact right scatter/board ZIP. Ask for help on XDA if model is old/uncommon.
