you chose flash all and lock, it locks the bootloader back again. in order for you to unlock it, open a cmd window then enter this
Code:
fastboot flashing unlock
this unlocks the bootloader again. try reflashing the stock rom with flash all files, don't tick the lock checkbox.

Won't work. For that to work you have to boot the os, go into developer options and enable OEM unlock.
Without being able to do that the only thing that can be done is flashing in edl mode

Hi, I have problem with service menu. When I select BOOTLOADER UNLOCK CHECK I get message that hiddenmenu stopped working. I never tried to unlock my bootloader and I have stock ROM V20C. Is possible that I can't unlock bootloader now ? Before few months I didn't have this problem.

via fastboot ? how ? I thought that fastboot will be available after bootloader unlock...
It is, technically you can access fastboot with omap4boot but you can't unlock from that or from normal fastboot because it is disabled until the boot loader is unlocked.

How did u enter on fastboot mode? I can't find the correct key combination, and adb reboot-bootloader doesn't work...
EDIT: I've used an TWRP Installer APK which just unlocked bootloader and installed twrp, rebooting to it and now I can enter fastboot by rebooting to bootloader in TWRP
Hello, I need to install recovery on my phone, downloading TWRP from the official site. Successfully flash, but my recovery does not work. Bootloader I'm unlocked. I've tried multiple versions but still the same. Will anyone please advise what to do with this? Thanks
Heyyo, hmm are you following a guide such as this one?
https://forum.xda-developers.com/le-max-2/how-to/protocol-backup-stock-rom-flash-stock-t3517151
That's what I followed for my x829 and it worked flawlessly for me
I have already tried this according to these instructions. Still the same result, recovery can not control. Extract from cmd, am I doing something wrong?

Fastboot boot =/= fastboot flash
Fastboot boot is a temporary attempt to boot from your recovery image - once you end the session, you are still just working on stock recovery. You need to do fastboot flash recovery rec.img or whatever the filename is. Boot is intended to ensure compatibility before full installation.
It still does not work to do what I do... I install the Recovery, but I do not want to click anything on it...
Install this https://androidfilehost.com/?fid=457095661767101877
It does not help, I still can not control recovery... I do not know what to do anymore.
Hello everybody,
Just got the phone yday so i still have to create my pefect setup....
In the meantime, what we learned by Oppo is that their System is closed, and will be very difficult to unlock the bootloader and then root.
When I enabled the dev options I'm seeing:
OEM Unlock(allow unlock of bootloader) look at the screenshot.
Can this bring us to somewhere?
I will wait for more experienced user feedback.
Thanks

it does nothing currently
adb reboot bootloader will only reboot the phone
vol up + power cannot boot the phone into recovery mode
so far, only thing works is the qualcomm flash mode, however, there is no leak of complete firmware just yet...
If you Google other oppo recovery steps you'll find there is a recovery...

Recovery is vol down and power.
So I was trying to root but something went wrong down the road.
Here's what I do :
Installed Magisk then patch the boot.img from decrypted OZIP file > Boot to Fastboot > (On PC) "fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification" returns success > "fastboot flash boot image_name.img" returns success > Reboot and realizes that it boots back to Fastboot again
Then I found someone saying this
On Fastboot, run "fastboot erase recovery" and "fastboot erase boot" and then I rebooted.
Now I am stuck at this screen

Holding down POW button does nothing or POW + VOL Down or Up. Is there anything I can do at this point? or is my only option is go to service center?
Tutorial that I followed : https://forum.xda-developers.com/t/guide-root-the-realme-x3-superzoom-with-magisk.4136333/
EDIT : I managed to drain the battery and booted back to Fastboot now. still from here I have no idea for now since flashing stock boot.img and vbmeta.img also cause bootlooping now
