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.

Old phones / phones without UFS flash type: vol+vol- and connect USB cable.

Important: SD-card should be removed from the phone.

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

If you mix up the order of flashing, this will cause phone's death!

Old phones / phones without UFS flash type:
FLASH FILE 1: Select UPDATE.APP flash file
FLASH FILE 2: Select localization/customization file (if your firmware contains this *.APP file)

STEP 5: Write Flash:

1. Press “Write flash” button
2. Perform Wipe Data/Cache via phone's recovery
