[Huawei Y5 (2017) Questions & Answers] enviro8:
I have prepared all the files that you will need to hopefully unbrick the Huawei Y5 2017 phone.

The following installs the system and boot files, and if you want, recovery or TWRP. This is a stock firmware but may not be your original stock firmware.

I extracted the from an update firmware, update.app. This update is designed to work with the original locked and unrooted phones but cannot be used with unlocked rooted phones. You need to have your phone connected to a PC and the phone and the PC need to be able to communicate. To do this you need the appropriate Huawei drivers for your PC. I have uploaded a driver installer that should work with the phone (see below to download). If you can already communicate, then skip this.

Fastboot, a DOS command, is used to flash the appropriate files to the phone.

To use fastboot you need to get into Command Prompt and change directories to where adb.exe, fastboot.exe and support files are located. You also need to have the four files in this directory. I have uploaded a file that contains all the files needed, Adbub.zip (see below to download). Download, unzip and copy the folder to the root of C:/ drive of your PC. In addition to adb.exe, fastboot.exe and support files, this folder contains the four additional flashable .img files

These files are: boot.img, system.img, recovery.img, twrp.img

If you already have the adb.exe, fastboot.exe and support files, then I have uploaded the four .img files as a zip, Images.zip (see below). Download, unzip and copy into the folder where your adb.exe, fastboot.exe and support files are.

After downloading, unzipping and arranging your folders you are ready to start.

Get into cmd.

Method 1

In Windows 10 (it is similar to Windows 8.1) open search and type in cmd and open Command Prompt.

Assuming that the folder containing adb.exe, fastboot.exe and support files and the img files is in a folder in the root of the C:/drive, enter:

cd.. (then enter)

cd.. (then enter)

You should be now be in the root directory of C:/ drive.

cd adbub (then enter) and you should be in the root folder:

C:/adbub

Method 2 (PowerShell – Windows 10)

Open the folder containing adb.exe, fastboot.exe and support files and the img files, do a Shift – Right Click and select Open PowerShell window here and after a few seconds a command prompt will appear.

Fastboot

We are now ready to flash the img files across. I did have a problem sometime when unbricking, in that fastboot reported more than one device was connected and would not work. I don’t know the reason but I fixed it by rebooting the phone into fastboot and/or rebooting the PC and continuing on with the next flash img. It says Fastboot in small writing on the bottom left of the screen. You need to be in the folder that hold adb.exe, fastboot.exe and support files and the img files.

The two methods I used are: From the phone in an OFF state and From the phone in TWRP

From the phone in an OFF state

Insert the micro end of a USB cable into the phone.

Hold in the volume down button

Insert the large end into the PC USB port and the phone will boot into Fastboot

Alternately hold the volume down button and push and hold in the power button until it reboots into Fastboot

From phone in TWRP

In TWRP, I did a Wipe, Factory Reset and Advanced Wipe and wiped everything except the micro SDCard. If you want, you could not wipe Internal Storage and Data (however your Data may be corrupt and you may need to repeat the process and wipe Data next time around).

In TWRP navigate to Reboot – Bootloader and boot into Fastboot

Flashing the Files

In either the Command Prompt or PowerShell and from the directory containing adb.exe, fastboot.exe and support files and the img files issue the following exactly:

fastboot devices

This will give a response something like:

PS C:\ADBFB> fastboot devices

R9KBB17C05205843 fastboot

fastboot flash boot boot.img

If successful a message will be shown

fastboot flash system system.img

This will take some time to come up but will eventually. It will flash the system.img as 22 or 24 parts and can take quite a few minutes to complete

fastboot flash recovery recovery.img

If you want to flash the stock recovery use this. It will overwrite TWRP and delete it. This step is not mandatory.

fastboot flash recovery twrp.img

This will flash another TWRP and replace the existing TWRP or install TWRP

fastboot reboot

This will reboot your phone into a stock as new format and you will need to re-enter all the data and info.

Restore a Backup

Immediately after one of my numerous unbrickings I did a TWRP Backup. I do not know if it is transferable or not, but if you want it copy to the micro SD card in the correct folder. If you do not know the correct folder, do a TWRP backup, remove SD card and open it in your PC. It should be in the folder TWRP – Backups – MYA-L22 or similar. Then restore my backup. The file is Factory Reset No Data (see below)

Finally, Good Luck and let us know how you went
