You need to wait till realme/Oppo releases the app specific to this phone. If you google the app, you will find plenty of sites say that the app for realme 3 or X will work but just a waste of time. Has to be for this phone

Though I am looking into a possible way to root device without unlocking bootloader.

Sorry for the stupid question, but I'm not even able to enter fastboot mode: pressing Volume Up + Power buttons simply reboots the system and sending "adb reboot bootloader" gives me a terminal message ending with "the serial is not match, fastboot_unlock_verify fail"...
What's wrong?

As per my my previous comment. Realme releases an apk file that then allows you to unlock the bootloader

While the bootloader is locked on any android devices, you will not be able to boot to fastboot.

I have managed to flash a magisk patched boot.img file by other means but wasn't successful, ass need to patch Vbmeta and can't do that without fastboot or two(or equivalent).

The apk they release is called deep testing. If you go on realme forums they are generally pretty open and quick to release. The app Is pretty much the equivalent of applying to Sony on the xperia's the app does the unlocking et

If I can find a way to get pasted the red state boot screen iI will defiantly post the instructions and all files etc

Ok i found this one too, and it is looks more trustworthy 🤔.

Well, i believe to you, so i will wait your response.
That will be the method, though realme still have not released the unlock tool for this device.

If you check the realme community forums, and see h bootloader unlock for this device on a periodical basis realme will eventually release it, just not sure on their time frames. This is only my second realme device of which the first one I once the c3 had already been out for a while and unlock tool was already released.

Once it has been. I will create. Thread with the process and attach the files here in xda

I have had a read through. Getting to brom bootloader and bypassing da was the way I was attempting it I am curious as to what is different between his magisk all and the app release he does.

I haven't had a look at the other one yet. WL do that tomorrow

I installed a linux distro today and tried again, i get same result as on windows.

If you get the same result, we'll assume it's caused by the device.

In this case, there is nothing left except creating a new issue on the github repo.

@

MrMiyamo are you successfully booting into the brom bootloader? as the instructions on github are only saying to power + vol up or down - when it is power + vol up + vol down and then plug in usb. I have just had to reinstall windows so i will give this a go as just installed python.​


give me a few hours to play around and see what i can do - i maybe able to do it the way i was doing it with the magisk app released on github page

@MrMiyamo while phone is turned on - push an hold power + vol + + vol - and continue to hold while it reboots, continue holding while you see at bottom of the screen rebooting to recovery - continue holding the keys down and plug usb in with other end connected to the computer

mind you im getting stuck at the da sync - try doing same process on linux - as i havent installed it yet and awaiting for it to download

I am run "sudo mtk rl out" and it looks like does the job, it currently dumping all partitions.

Edit:

Ok, i did something stupidly and installed linux system on 24 GB partition

so I had to stop the process before it complete,

It's probably fine as long as we don't want a backup, but I'll install the system on a 64gb partition and look again later.

thats awesome - so it appears to be a windows issue - i will create the issue on github soon - :) we have progress

also i found out that it only needs to be phone switched off and vol + & vol - held while plugging in usb :)

with that working -then the rest of the instrcutinos should work - so give it a try - i just finished downlaoding linux- so i will be a little while off trying it

i think i know what the windows issue is - its not picking up vcom drivers in the transition from bootloader to vcom - so therefor it stalls -

BTW my phone has a pending OTA update, i keep to not update since i worry about that method will not work.

Can i apply OTA update without worry?
Else how can i remove pending update files?
while your phone is not updated - lets leave it like that - as mine is latest firmware - hence we maybe getting to different issues.,

this way we can attack 2 different firmware versions. yep saw your editted mesage - i had to install another hdd to install just for the moment ...


but at least the mtk rl command worked and got further then I did on windows - im about halfway through linux install (just have to remember how to use the bloody thing now haha)
