Fix Huawei P20 Bootloop, Dead Boot & System Failures with Official Stock Firmware
The Huawei P20, announced in March 2018, is a flagship smartphone powered by the HiSilicon Kirin 970 processor (10nm), featuring a stunning 5.8-inch FHD+ display, professional dual-camera system with AI enhancement, and premium build quality. However, users worldwide have reported severe software issues including persistent bootloops where the device repeatedly restarts on the Huawei logo, dead boot scenarios with a completely black screen, “System UI has stopped” crashes, catastrophic battery drain after EMUI updates, Wi-Fi and mobile data disconnections, and system freezes after failed OTA firmware installations or improper root attempts.
The official firmware recovery packages below are the definitive solution for these critical software defects. These verified factory stock ROM files repair corrupted system partitions, resolve EMUI compatibility issues, fix bootloader problems, and completely restore your Huawei P20 to its original state. Supporting multiple regional variants (EML-L29, EML-L09, EML-AL00, EML-TL00) and EMUI versions (8.1, 9.0, 9.1, 10.0), these files are essential for unbricking devices when standard recovery mode fails.
🔴 CRITICAL WARNING: Wrong Firmware = Permanent Damage
The Huawei P20 exists in four distinct regional variants: EML-L29 (Global/Europe), EML-L09 (Global/International), EML-AL00 (China), and EML-TL00 (China Telecom). Flashing incorrect firmware for your device model will result in network incompatibility, invalid IMEI, SIM card not recognized, or complete bootloop. The device may also enter a “Red State” where it refuses to boot. Additionally, incorrect flashing procedures can permanently brick your device. Always verify your exact model in Settings → About Phone before proceeding. This process will completely erase all personal data, including photos, messages, and apps. Ensure your battery is charged above 60% at all times—power loss during flashing causes irreversible hardware corruption.

Regional Selection Guide: For European/Global users with EML-L29, use the C461E3R1P3 EMUI 10.0.0 build (latest and most stable). For international users with EML-L09, use C432E7BR1P3 EMUI 10.0.0. For Chinese users, select EML-AL00C (C00E181R1P4) or EML-AL00A (C00E170R1P4) based on your exact variant. For China Telecom, use EML-TL00 (C432). If you’re experiencing EMUI 10 instability, downgrade to the latest EMUI 9.1 variant for your region.
Before You Begin ⚙️
- 💾 Backup All Data: Flashing will permanently erase all personal data, including photos, videos, messages, contacts, and apps. Use Google Drive, OneDrive, or local computer backup before proceeding.
- 🔋 Charge to 60% Minimum: Ensure your Huawei P20 battery is charged to at least 60% or higher. Battery depletion during flashing causes permanent motherboard corruption.
- 💻 Use Reliable PC: Connect via a Windows 7, 8, 10, or 11 computer with stable USB connections. Avoid USB hubs or wireless connections—use direct USB 2.0/3.0 ports.
- 🔌 Quality USB Cable: Use the original Huawei USB Type-C cable or a certified high-quality replacement. Defective cables interrupt flashing and cause device corruption.
- 🧩 Install USB Drivers: Install Huawei USB drivers or Kirin 970 chipset drivers on your PC. Drivers enable proper device communication and detection.
- 📥 Download Tools: Install HiSuite (primary method), MediaFire or Google Drive (for file access), and backup tools before starting.
- ⚡ Disable Security Software: Temporarily disable Windows Defender, antivirus programs, and firewall—these may block flashing tool access.
- 📱 Verify Your Model: Confirm your exact model (EML-L29, EML-L09, EML-AL00, EML-TL00) in Settings → About Phone before selecting firmware.
📱 How to Flash Huawei P20 Firmware
Dload (SD Card Recovery)
If HiSuite fails or your PC cannot detect the device, Dload recovery via microSD card is an effective alternative for P20 models.
- Extract Firmware: Download and extract your firmware file using WinRAR or 7-Zip. Locate the file named de>UPDATE.APP inside the extracted folder.
- Prepare SD Card: Format a microSD card (8GB or larger) to FAT32. Copy the de>UPDATE.APP file to the root directory (not in any subfolder).
- Insert SD Card: Power off your Huawei P20 completely. Insert the prepared microSD card into the device.
- Enter Dload Mode: Hold down Volume Up + Volume Down + Power simultaneously for 10 seconds. The Dload recovery screen will appear (black screen with Huawei logo and “Dload” text).
- Automatic Flashing: The device will automatically detect and flash the UPDATE.APP from your SD card. A progress percentage will display. This process takes 5–10 minutes.
- Reboot: Once flashing reaches 100%, the device automatically reboots into Android. Remove the microSD card and wait for the system to fully boot (5–10 minutes for first boot).

Frequently Asked Questions (FAQs)
How do I know my exact Huawei P20 model?
Go to Settings → About Phone. Look for the “Model” field. You will see one of: EML-L29 (Global/Europe), EML-L09 (International), EML-AL00 (China), or EML-TL00 (China Telecom). Additionally, check the CUST code (e.g., C432, C461, C00E) to identify the exact build variant. Download firmware matching your model exactly.
Can I flash EML-L09 firmware on an EML-L29 device?
No. Absolutely do not attempt this. Each model variant is optimized for specific network bands, carrier settings, and regional infrastructure. Flashing mismatched firmware will result in no network signal, 4G not working, invalid IMEI, or complete bootloop. Your device may become unrecoverable. Always flash firmware matching your model exactly.
After flashing, my phone asks for Google account verification. Is this normal?
Yes, this is Factory Reset Protection (FRP). After clean firmware flashing, your device requires you to enter the original Google account (Gmail) that was previously synced to unlock the device. If you forgot the account, you can reset it via Google Account Recovery on a computer, or use the same Wi-Fi network the original account used. FRP is a security feature that cannot be bypassed.
Can I downgrade from EMUI 10 to EMUI 9.1 or 8.1?
Yes. The firmware packages above include EMUI 9.1 and 8.1 versions for downgrading. If EMUI 10.0 causes performance issues, battery drain, or compatibility problems, you can downgrade to the latest EMUI 9.1 or 8.1 build for your model. Simply flash the older EMUI version using HiSuite or Dload. After downgrading, avoid taking OTA updates unless they’re specifically for the older EMUI version.
My device is stuck at “Connecting to update server” or flashing failed. What should I do?
This usually indicates a driver or connection issue. Try: (1) Reinstall Huawei USB drivers and Kirin 970 chipset drivers, (2) Use a different USB port (preferably USB 2.0), (3) Try a different USB cable, (4) Disable antivirus/firewall temporarily, (5) Ensure battery is above 60%, (6) Try the Dload method instead of HiSuite. If problems persist, the USB port or motherboard may be damaged.
Can I use these firmware files to restore my P20 to warranty status?
Yes. Flashing official Huawei firmware typically restores warranty eligibility if your device was previously rooted or modified. The stock firmware removes all traces of custom ROMs, root access, and modifications. However, physical damage or water damage will still void warranty. It’s advisable to contact Huawei support before flashing if warranty restoration is critical.
