About the Huawei P Smart 2019

The Huawei P Smart 2019 was released in January 2019, built on the HiSilicon Kirin 710 (12nm) platform. Featuring a 6.21-inch FHD+ dewdrop display, a 3400 mAh battery, and microUSB OTG connectivity, the Potter family encompasses several regional variants including POT-LX1, POT-L21, POT-L21T, and POT-LX1A.

Flashing factory stock firmware via Huawei Dload restores broken system partitions, cures boot loops, and removes unwanted modifications. Follow the verified preparation steps and procedural instructions below to flash your device safely.

Which Flash Mode Should You Use?

Huawei eRecovery Mode (Wi-Fi Emergency Restore)

Over-the-air emergency recovery tool built into Huawei Kirin devices. Connects to Wi-Fi to download and flash the latest approved firmware for your specific serial number.

How to enter
Turn off phone, connect USB to PC/charger, hold Volume Up until eRecovery menu appears
Requires
Wi-Fi connection, microUSB charging cable, PC or wall adapter

Factory Test Point (HiSilicon USB COM 1.0)

Low-level hardware unbrick procedure for hard-bricked devices that show no display. Used with Huawei Board Software packages and IDT to restore boot partitions.

How to enter
Disconnect battery, short test point to motherboard ground shield, and connect USB cable to PC
Requires
Motherboard test point connection, Windows PC, HiSilicon COM 1.0 drivers, IDT software

What You Need Before Flashing

1
FAT32 Memory Card or OTG Drive

An 8 GB or larger microSD card or USB OTG flash drive formatted with FAT32 file system and MBR partition layout. exFAT is not supported by EMUI recovery.

2
Matched Regional Firmware

Download the package matching your exact model number and regional Cust tag (such as POT-LX1 C432 Europe). Check Settings or eRecovery before downloading.

3
50%+ Battery Level

Ensure the non-removable 3400mAh battery holds at least 50% charge to prevent unexpected shutdown during eMMC partition writing.

4
Reliable microUSB Cable

Use a verified microUSB data cable connected directly to the phone. Charge-only cables will not support emergency USB recovery.

5
Data Backup

Flashing stock firmware via Dload wipes all user data and installed apps. Back up personal files before proceeding.

How to Flash the Huawei P Smart 2019 β€” Quick Overview

A fast reference for flashing the Huawei P Smart 2019 (Kirin 710) using Huawei UPDATE.APP. For the complete walkthrough with images and error troubleshooting, see the full guide.

  1. Format a microSD card or USB OTG flash drive to FAT32
  2. Extract firmware archive and create "dload" directory
  3. Connect storage media to the phone
  4. Trigger 3-Button Dload recovery mode
  5. Allow automated partition flashing to complete

Firmware Package for Kirin 710

Official Huawei stock firmware packages for the P Smart 2019 family are delivered as container archives containing UPDATE.APP. When extracted onto a FAT32 storage medium, the stock recovery partition parses UPDATE.APP to flash system, vendor, product, and kernel partitions over the low-level Dload installer.

UPDATE.APP

Official Huawei stock firmware is supplied as an archive containing UPDATE.APP. Extract the archive and verify that UPDATE.APP sits directly inside a folder named "dload" on the root directory of your FAT32 memory card.

The Huawei P Smart 2019 family is built on the HiSilicon Kirin 710 (12nm) platform under project codename Potter (POT). Hardware variants include the dual-camera P Smart 2019 (POT-LX1, POT-L21, POT-L01), the triple-camera P Smart+ 2019 (POT-L21T, POT-L01T), the refreshed P Smart 2020 (POT-LX1A, POT-L41B, POT-L42B), and Chinese releases (POT-AL00, POT-AL10).

Flashing stock firmware via Dload does not require an unlocked bootloader. However, Huawei security requires strict matching between the package regional Cust tag (e.g. C432 Europe, C431 EEA, C185 Middle East, C10 Russia, C00 China) and the phone motherboard OEMinfo partition. Cross-flashing incompatible regional packages will result in verification failure.

Huawei P Smart 2019 β€” Important Notes

The Huawei P Smart 2019 and P Smart 2020 carry official Google Mobile Services certification. Performing a clean stock firmware flash preserves certified status, allowing Google Play Protect, Google Wallet, and banking applications to function normally.

If your device is completely bricked (black screen, no vibration, unable to boot into recovery), standard Dload flashing will not initiate. In this state, technicians use factory Board Software packages alongside hardware test point bridging to enter HiSilicon USB COM 1.0 mode, writing initial bootloader partitions via Huawei Image Download Tool (IDT).

Troubleshooting Huawei P Smart 2019 Dload & EMUI Installation Errors

EMUI Verification Error: "Incompatible Cust Package" (C432 / C431 OEMinfo Rejection)

Community repair discussions indicate this error occurs when attempting to install open European C432 firmware onto an operator-branded C431 EEA or Middle Eastern C185 handset. The Kirin 710 bootloader refuses Dload execution if the carrier-config tag does not match the OEMinfo string. Technicians recommend verifying the exact Cust branch in eRecovery before flashing.

Installation Stalls at 5%: "UPDATE.APP Package Integrity Verification Failed"

Usually caused by slow memory card read latency or corrupted multi-part archive extraction on Potter hardware. Repair forum members suggest re-formatting the microSD card as MBR FAT32 (allocating 32KB clusters) and verifying the archive MD5 checksum before copying UPDATE.APP to root "dload".

Device Manager displays "HUAWEI USB COM 1.0" but disconnects after 3–5 seconds during IDT flashing

Occurs during hardware test point recovery when the battery cable remains attached or when using an unpowered front USB port. Bench technicians advise disconnecting the internal battery flex cable before grounding the test point to the shielding can, and using a native motherboard USB 2.0 port.
