Hello everyone. I've got a problem after trying to flash my realme 8 according to this guide and now my phone is bricked. I have infinite black screen with white realme logo and "Recovery mode" text in the bottom of the screen.
I did everything accoding to the tutorial except step 11.

Could someone help me?
I cannot open stock recovery menu, but I've tried to wipe all data after flashing using
python mtk e metadata, userdata, md_udc
but it didn't help neither.

Thanks in advance.

Hello, I am at step 7 and I keep getting the error "handshake failed". Tried to reinstall everything and re-do from step 1 running as administrator, however I only get the same result. Anyone has advice? Thanks in advance.

Tried with another computer and it works now. I'm trying to flash any global android 11 roms. .22 or .26 only bootloops into recovery. Formatting in recovery doesn't help. Only boots up when I flash global .24 but it boots into the Indian .24 (for which I accidentally downgraded to previously and trying to switch form now as I need the NFC function on a daily basis) . Anyone had similar issue? Whenever I try to flash another rom, I reinstall drivers, python, etc. so I actually follow all the steps in the description.

Noticed that at step 10, it says unpick 2 of the list, but on the pictures a 3rd one is unpicked as well (md1img). Should that be picked or unpicked?

    Hello everyone! So after the new MediaTek DAA and SLA protection bypasses you can find GitHub repo of here , using the bypass we are able to use SPFlash Tool, here is a guide how you can do it! This guide is for RMX3085 (Realme 8) ONLY. DON'T DO ANY OF THESE IF YOU HAVE SOMETHING ELSE!

    ALWAYS USE DOWNLOAD ONLY MODE OF SP FLASH TOOL.
    DON'T TOUCH ANYTHING RELATED TO FORMAT ON SP FLASH TOOL! (IT'S WRITTEN EVERYWHERE, YOU WILL LOSE YOUR IMEIS IF YOU USE FORMAT ALL + DOWNLOAD. YOU ARE SAFE IF YOU USE DOWNLOAD ONLY.)


    Requirements:
    • PC or Laptop
    • Internet connection
    • Realme 8
    • USB cable
    Windows Method
    Requirements:
    Bypass Tools Pack - (DRIVER AND BYPASS FILES)
    SP Flash Tool

    Decrypted OFP (OPPO FIRMWARE PACKAGE) :
    Indian

    A.22 (Indian) - GDrive
    A.24 (Indian) - GDrive
    A.26 (Indian) - Gdrive
    C.05 (Indian) - GDrive
    Global
    A.22 (Global) - GDrive
    A.24 (Global) - GDrive
    A.26 (Global) - GDrive
    Install Python from Windows Store
    libusb-win32 - Having Issues? Use this.
    Get usbdk installer (.msi) from here and install it

    Steps:

    1)
    Extract the zip
    2) Go to driver folder, find the .inf file right click and press install.

    3) Download this file and install it, after installing power off phone and connect to pc while holding Vol+- (don't leave the buttons after connecting) . You might need this driver as well if it's not detected.

    4) Press next, connect your device to PC while holding Vol+- buttons (your device needs to be powered off, and don't leave the buttons) and you will see the mtkdriver down below. Install it.

    5) Choose MediaTek USB Port and install it.

    6) Then run the brom.bat under Bypass folder.

    7) Now power off the phone and connect the phone while holding volume + and - (Don't leave the buttons until the bypass is done)

    8) After the above step Go into Flash Tool folder and open the SPFlash tool go to Options>Option

    9) Click on Connections and select UART and set Baud Rate to 921600

    10) After that choose scatter file and also if not set, set your download-agent. You don't need to select auth file as authorization is disabled. Once you do it, it should look like this. ALWAYS MAKE SURE DOWNLOAD ONLY MODE IS SELECTED! DON'T SELECT OTHER MODES!
    1642842374170.png

    • Select all the Partitions except opporeserve2 and cdt_engineering. otherwise you will get errors.
    *11) If you want to flash super.img partition also then download this scatter.txt file and replace it with the another scatter file which is present in the decrypted firmware folder. After that select it again in sp flash tool.

    Again Make SURE "Download Only" is selected. Don't select ANYTHING ELSE! You will lose your IMEIs, Serial Numbers, Capability of Hardware Attestation etc. if you choose "Format data + Download" make SURE you selected "Download Only".

    Now, you can start downloading with the button and after that a checkmark will appear. You can reboot your phone and use it like before now! All your userdata will (inevitably) be cleared!

    After flashing it should look like this. Download has been complete. Enjoy!

    If you face any issues write them down below...

    if "Brick" occured in rooting process - then can recovery be done without data loss :

    Prerequisite: firmware version on the body must the same as downloaded "Decrypted OFP" (as example both is A.22 )

    HowTo:
    at step of SPFlashing (currently that is 10-th)
    - check ONLY next partitions in SPFlash to restore :
    PRELOADER RECOVERY VBMETA LK LK2 BOOT
    ... and NO any of other
    (as thats only are touched by currently described rooting processes)

    Does the phone warranty will be void once the brom.bat ends its work?
    The warranty will be valid.
    If you want to return the phone to the service, lock the bootloader and say that it is after the update.
    They will load original system and after problem data will be lost

    Some people having this problem so I want to add one more thing to the guide. If you are not having any issues related to boot then don't follow these steps.

    After waiting more then 10 minutes, if it doesn't boot up/bootloop. Or shows DM-Verity corrupt error then do this.

    1) Try boot into stock recovery by pressing volume up + power button after that when your screen flashes quickly unpress buttons.

    2) Now press volume down + power button, by pressing these you will boot into stock recovery.

    3) Go to format option and do a full format.

    4) Your phone will definitely boot up after that.
