Hi again,

The thing is I really am stupid so I really need your help again.

My problem is I wanted to remove twrp through factory reset, but I accidentally ticked off the wipe internal storage box from the advanced wipe through twrp. Now when I rebooted, I am stuck at the end of first time setup "Checking for new updates" and I can't boot into recovery it just says "The serial doesn't match, fastboot_mode_verify_fail"

Im guessing I removed the ROM as well as TWRP???, I really hope I'm wrong

Any help would be really appreciated!!!

How do I install OTA update through twrp, whenever I go into the ota directory I am faced with multiple of this zips that I dont know which to flash. I am guessing the files for some reason were not compiled into one folder.

I don't have stock recovery for every version of ROM...so download the stock rom for your respective region and version and decrypt using https://github.com/bkerler/oppo_decrypt

Also, if it's ok can you expound on this?

Like what should I do next after downloading the stock rom for my phone (A.35, PH) I quite don't get the decrpyt part since Im afraid im just a casual phone user and can't find worthy articles for the topic.

thanks!

You just want stock recovery image right? Decrypt that stock rom with the tool in the link... Then get the stock recovery image from there... Then you can flash stock recovery.

Glad to know that!

One last thing, what directory should I put here? The tool always return " the system cannot find the path specified" even though I inputted the directory where I downloaded the stock ROM

For your reference:

Tried the directory while connected to the pc:

    Hi Guys!

    Since there is no deeptest.apk available for our device to unlock bootloader, we came up with another method to unlock bootloader unofficially!

    In this guide I'll tell you how to unlock bootloader, root with magisk and flash TWRP on your Realme 8i/Narzo 50 (RMX3151/RMX3286)

    Code: 
    /*
* This Guide is tested and working
* However I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about unlocking and flashing TWRP
* before flashing it! YOU are choosing to make these modifications.
*/


    1. UNLOCKING BOOTLOADER:

    Requirements
    • PC or Laptop
    • Internet connection
    • Realme 8i/Narzo 50
    • USB cable
    • Working Brain
    • Take a backup of your data since it'll be wiped
    • Go to About phone > Version and tap build number 7 times
    • Go to Settings > advanced settings > Developer options and turn on OEM unlocking and USB debugging
    STEPS
    • Install Python from windows store
    • Install USBDk
    • Download this and extract : https://github.com/bkerler/mtkclient/archive/refs/heads/main.zip
    • Download vbmeta and patched boot image (Download for your respective version) in copy to the mtkclient-main folder
    • Now open command prompt or powershell in that folder
    • Screenshot (58).png
    • Now type pip3 install -r requirements.txt and hit enter
    • Now type python mtk e metadata,userdata,md_udc hit enter - This command wipes data
    • Then power off your phone and hold both volume buttons and connect usb cable (DON'T LEAVE THE BUTTONS, KEEP THEM HOLDING THROUGHOUT THE PROCESS) - This boots device into BROM mode
    • Now type python mtk da seccfg unlock This will unlock the bootloader (If you face waiting for device issue then unplug the device and plug in the device again with holding volume buttons, also don't leave the buttons)
    • IMG_20211201_212023_350.jpg
    • After this unplug your phone and turn it on (It'll show your device dm verity corrupted and first boot might take 20-25 mins, don't panic)
    • Now your bootloader is unlocked
    • 20211201_213428.jpg
    • Due to realme's limitations you still can't access fastboot after unlocking via this method
    2. ROOTING YOUR DEVICE:
    • Install This Magisk apk
    • Now in pc type python mtk w boot,vbmeta boot.patched,vbmeta.img.empty hit enter
    • Then power off your phone and connect usb while holding both volume buttons (and don't leave them)
    • IMG_20211201_213448_962 (2).jpg
    • Now disconnect and reboot phone
    • Now open magisk
    • IMG_20211201_213458_216.jpg
      IMG_20211201_213500_384.jpg

    3. FLASHING TWRP RECOVERY:
    • Download TWRP - From here
    • Download and install Flashify app
    • Open Flashify and grant root permission
    • Select Recovery image and install the twrp you have downloaded
    • IMG_20211201_220206_593.jpg
    • After flashing is done click reboot now or you can reboot to recovery via magisk app
    • IMG_20211201_221211_553.jpg
    "Congrats Now we have working TWRP in our Realme 8i/Narzo 50"

    English is required, you can use your native language too, adding it to your post.

    Inside the tool is provided a README.md file with basic instructions and usage. To relock bootloader you can use python mtk xflash seccfg lock just be careful to not relock it while running custom binaries, you have to return completely back to stock prior to do that.
