This feature allows setting the device to factory mode - HUAWEI USB COM 1.0 without disassembling the phone, and without connecting hardware testpoint to it. No need to search for the schematics of testpoints.

STEP 1: Prepare original update.app flash file

It must exactly match the smartphone’s firmware version:

• You may take it from update_sd_base firmware folder
• Use SD_update file type for the latest Android versions (Android 10.0.1, Android 10.1 and higher). Use the same or higher firmware version.
• Don't forget to write down for yourself original firmware version of the device

STEP 2: Software testpoint - ON

1. Select "HISILICON" platform from the tab menu in the upper left side of the software
2. Go to the "Service" bookmark

5. Press "Enter Rescue mode" button

1. Type #*#2846579#*# on the phone.
2. Go to Project Menu -> Network information -> vendor Country Info
3. Use original flash files with the same customization settings.

This feature is intended to be used for phones that won’t turn on, freeze on logo, etc., but still can enter fastboot mode. It's not intended for regular reflashing.

Procedure:

1. Connect the phone in fastboot mode (vol- power ON) to PC
2. Select corresponding firmware files just as it is described in the UPGRADE MODE flashing manual.
   Important! You will have to select different amount of files for phones with UFS flash type and for old phones / phones without UFS flash type. That’s why in each specific case you need to choose flash files for each certain phone/version.
3. When the phone starts up normally, reflash it in UPGRADE mode using the corresponding to it flash file

Benefits:

• Full/partial write of firmware partitions
• FAST direct firmware write via fastboot mode
• Flash of regular update.app files to devices with locked bootloader
• Possible to use original flash files from open sources, e.g. from here or here

STEP 1: Save (or write down) original version of your phone:

Read from Fastboot mode and write down for yourself:

• original phone firmware version
• original phone model
• customization version

You may use Get device info feature on Service tab, it reads the phone information from Fastboot mode.

STEP 2: Prepare the firmware files:

Unpack original Huawei flash file.
It must be full SD-Upgrade package, not OTA update.

Phones with UFS flash type:

The firmware consists of 3 archives. Every archive contains unique UPDATE.app and PTABLE.app files.

You need to unpack each archive. Don't mix up the files!

into separate folder!

• update_sd_base folder: UPDATE.APP and PTABLE.APP
• update_sd_cust folder: UPDATE.APP and PTABLE.APP
• update_sd_preload folder: UPDATE.APP and PTABLE.APP

Every folder has to contain UPDATE.APP and PTABLE.APP files.

Old phones / phones without UFS flash type:
Unpack update.app flash file and localization file (if your firmware contains this localization.app file).

STEP 3: Set the phone to Upgrade mode:

Phones with UFS flash type: Press and hold VOL+ and Power ON buttons. Select "Upgrade mode -> USB upgrade" from the menu that will appear.

STEP 4: Select files for flashing:

1. Open HiSilicon tab and go to Flash bookmark
2. Select PCUI port or DBA adapter port (different phone models show different ports) in the port selection tab
3. In case the phone does not enter Upgrade mode, try to enter it using Rescue mode entering manual
4. Select files for flashing:
   Phones with UFS flash type:
   Important! You need to select 6 files for flashing exactly in this order.

FLASH FILE 1: PTABLE.APP from update_sd_base folder
FLASH FILE 2: PTABLE.APP from update_sd_cust folder
FLASH FILE 3: PTABLE.APP from update_sd_preload folder
FLASH FILE 4: UPDATE.APP from update_sd_base folder
FLASH FILE 5: UPDATE.APP from update_sd_cust folder
FLASH FILE 6: UPDATE.APP from update_sd_preload folder
