How To Guide [CPH2239] How to Unlock Bootloader and Root the OPPO A54

[Sami sl]

Yes this is the exact issue users had been reporting. You can get stock rom file from here. Use oppo-decrypt (here) and extract the .ofp file of stock firmware to some folder. Use bypass_utility (here) to disable security otherwise we can't flash the rom using sp flash tool. Once security disabled flash the firmware using sp flash tool. While flashing make sure "opporeserve2" is unticked.

hey,im facing the same problem, i tried unlocking the bootloader using mtk game over tool, i got this error and my data wasnt wiped off, i probably think the bootloader is still locked, does ur method work without unlocking the bootloader and can u plz tell me how to do it

Make sure to downgrade your firmware to Android 10. Unlocking bootloader cannot be done on Android 11. Download the stock firmware of android 10 and extract it. I have shared the tools to extract the ofp file inside the stock firmware zip. Extract it and flash the firmware using sp flash tool. Make sure to use bypass_utility to disable security before flashing

2. Dump boot and vbmeta partitions by typing the below code

Spoiler: Show Code

python mtk r boot,vbmeta,vbmeta_system,vbmeta_vendor boot.img,vbmeta.img,vbmeta_system.img,vbmeta_vendor.img

Press Enter and insert the USB cable into your device by simultaneously pressing vol up and down buttons. If It doesn't work try again until it does

I couldn't do this step. I connect the phone to the pc, I press volume up and down and the phone turns on and nothing changes in the cmd.

Edit: Forget about it I'm stupid I didn't installed usbdk driver

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

This means the bootloader hasn't been unlocked yet. On which android version did you try to unlock bootloader?

a11 I'm trying to downgrade to a10 but I can't, do you have a tutorial step by step? (using sp flash tool)

GETTING THE STOCK FIRMWARE:
First download OPPO A54 stock rom from this link. Then extract it. After extracting you will see a file with that ends with .ofp . You should decrypt the ofp file to some folder with the help of this.

FLASHING STOCK FIRMWARE:

• Then download the Bypass_utility zip I have attached below. Extract it and open a command prompt window in the extracted folder.
• Type

  pip install pyusb json5

  . Once that's done type this command

  python main.py -c mt6765_config.json5 -p mt6765_payload.bin

  .It will show waiting for device. During that time insert a usb cable by pressing vol up and vol down. You will see a message "Protection disabled".
• Now don't remove the cable or close the cmd window. Open sp flash tool and select the scatter file which will be located at the folder to which you extracted the .ofp file. Select it and also uncheck opporeserve2 partition cause it might throw some errors. Then just click on Download and the flashing process will begin

SP Flash tool asks me for an authentication file, do i have to select it?

Edit: Forget about it I fixed it

 

[gitmg]

It worked thank you so much for the help

Hello.. You should be able to flash stock firmware even if bootloader is locked. Just don't flash opporeserve2. Cause that might give "not verified" error

Edit: Sorry I didn't read your message properly. Will you please send a picture of download not completed error that you have been getting?

it says "Download not completed! Please press volume+ and power key 10s to power off. Then download it again. Otherwise will block here 60s will shutdown automatically error code: 0x992566"

Edit: Maybe now I've tried every single firmware for a54 T.T but no help, someone said that I need to flash oppo_custom.img for oppo a54, I've downloaded it, but when I flash that oppo custom, it need a verified boot same as oppserve2... I have no idea and stuck here tryin to find another firmware...

DISCLAIMER​

* I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
* YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
* Your warranty will be void if you tamper with any part of your device / software.​

PRE REQUIREMENTS:​

• Python 3.9 and Git (Please make sure to add Python and Git to PATH. An option to add them to PATH will be available in the installer)
• mtk client (Get it from here)
• SDK Platform tools (Get it from here)
• Patience
• USB debugging and OEM unlock should be enabled in developer options

LET'S BEGIN!​

STEPS:​

1. Open Command Prompt in any location and type
git clone https://github.com/bkerler/mtkclient cd mtkclient pip3 install -r requirements.txt

2. Dump boot and vbmeta partitions by typing the below code

Spoiler: Show Code

python mtk r boot,vbmeta,vbmeta_system,vbmeta_vendor boot.img,vbmeta.img,vbmeta_system.img,vbmeta_vendor.img

Press Enter and insert the USB cable into your device by simultaneously pressing vol up and down buttons. If It doesn't work try again until it does

3. Patch the boot.img in Magisk manager and save the patched boot back to Platform tools folder and rename it to boot.img. Copy vbmeta,vbmeta_system and vbmeta_vendor as well to Platform tools folder

4. Unlock the Bootloader
Execute the below commands:

Spoiler: Show Code

python mtk e metadata,userdata,md_udc
python mtk da seccfg unlock

NOTE THAT AFTER EXECUTING EACH COMMANDS YOU MIGHT HAVE TO RECONNECT YOUR DEVICE. YOU CAN ALSO PERFORM THIS STEP USING THE MTK CLIENT GUI. FOR THAT FOLLOW THE BELOW STEPS

In a command prompt window opened in mtk client folder type
python mtk_gui

Once you are in the GUI connect your device by inserting usb cable and pressing vol up and down buttons simultaneously. Once the device is recognised few tabs will show up. Head over to the erase tab and Erase metadata, userdata and md_udc partitions. Then press the Unlock bootloader button.

Reboot the device now. You should see an orange state warning during start up.

5. Reboot back to fastboot
To do this open a command prompt window in Platform Tools folder and execute

Spoiler: Show code

adb reboot fastboot

6. Flash the patched boot.img and vbmeta
Move the patched boot.img, vbmeta_system and vbmeta_vendor to platform tools folder. Execute the below commands in a command prompt window opened in Platform tools folder

Spoiler: Show code

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system vbmeta_system.img
fastboot --disable-verity --disable-verification flash vbmeta_vendor vbmeta_vendor.img
fastboot flash boot boot.img
fastboot reboot

THAT'S IT! NOW YOU SUCCESSFULLY HAVE ROOT IN YOUR OPPO A54​
