Yes you have to pull your boot image first and patch it
Pulling boot image via mtkclient

Code:
python mtk r boot,vbmeta boot.img vbmeta.img

After pulling the boot image patch it with the magisk apk given in the post

After patching the patched boot image will be in your phones download folder, rename that to boot.patched and flash with mtkclient as mentioned in the post 👍🏻
Thanks. But does magisk need root access to patch boot image?

ight im here just to making 3x sure

  • im currently at build A.41, theres only A.35 Patched image in the mega folder. However, i can just pull tf out of my device boot.img and patch it my self with magisk and use it for this steps, is it correct?
  • vbmeta one is universal, it works with all version of build image, is it correct?
  • i dont understand "dont leave the buttons" part, should i press them till the boot process complete or should i press them and never release them even after booting? what happen if i release them? how should i type the command if my both (sweaty) hand are holding the buttons?
  • i came just for root process, is twrp necessary here? can i just skip the twrp part? do we have some nice custom roms for realme 8i?
  • will you help me if i nuked my device and i dont know what to do?
  • can i ask for estimated success rate for this?
sorry for too many questions

Hello, I have a Realme 8i.

I have a few questions which might help others too -

1. Do GSIs work?
2. Does RMX 3151 have dynamic partitions? I want to use phhusson's GSI which has OTA updates support.
3. Can I pass safetynet using Magisk on this phone? I've had problems on some phones even after using universal safetynet patch.

Thanks for doing this tutorial.

Realme 8i
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
  • View attachment 5472417
  • 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)
  • View attachment 5472431
  • 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
  • View attachment 5472457
  • Due to realme's limitations you still can't access fastboot after unlocking via this method
2. ROOTING YOUR DEVICE:

3. FLASHING TWRP RECOVERY:

Hi, first i have read whole thread entirely and also unofficial TWRP website and the DM-Verity Opt-encrypt indian website too.
i own a RMX3286 Aka Narzo 50, with firmware version A.50 Export, i have fully followed instructions here, apart from the boot.img that i dumped myself and patched with magisk 23 prior to flashing.
Phone is running ok, unlocked BL, rooted, and TWRP installed !
So a Big thanks to you all for your work !
I'm not new to rooting, unlocking BL, and custom firmwares, already did on most phones i owned past 10 years.

So far so good, i still have some questions unanswered :

Is .bin backup made with Flashify same as .img backup from mtk client ? Can rename from one to the other ? safe to flash .bin through mtk client ?

Is magisk 24.2 working or we need to stick to the magisk 23 of this thread ?

I can't make backups with TWRP 3.6.1_11-0-spaced version, always throw error with 'tar' at the end of backup process, already tried all possible TWRP options i think... Any solution ? Flash unofficial TWRP 3.6.0 and flash no-verity-opt-encrypt at same time through current TWRP is going to work ?

Solution :
Narzo 50 is using kind of ram on disk to add more available memory, in my case 6gb of Real RAM + 2gb of on disk memory.
So go to Developper options > Memory and disable the added memory, keep only real RAM.
Reboot phone fully once, allow system to start.
Reboot in recovery, in TWRP start the backup... No more errors.

Didn't found this solution anywhere on the web, as everyone is pointing out to delete some folders or disable Cloned apps if you use it.

When I execute the cmd "python mtk da seccfg unlock" it will show this error, I did wipe using the mtk cmd twice but still not working. Running on A36 btw.View attachment 5517115

I'm having issues on camera, it crashes when I'm trying to open it. Is there any fix for this?
im having the same issue where it showed you that error when you executed "python mtk da seccfg unlock" what did you do to fix it?

    Добрый вечер.А как теперь заблокировать загрузчик,подскажите пожалуйста.
    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.
