Okay, so it looks as if Fastboot is disabled on my device. I went into the Stock Rom, and I found there is a switch on the Stock Rom that turns Fastboot on and off. It says: Allow Oem Unlock.
I've heard of some folks bricking their Phones this way by flipping this switch in the stock rom. Is that true?
My choices seem to be:
1. Use SP Flash Tool to Flash TWRP. Then TWRP to load AOSP Extanded, or Lineage.
2. attempt to use that switch to see if it will let me do a fastboot oem unlock.
I'd like to try the second, but I want to know if thats a land mine to a bricked Phone if I flip the switch to allow OEM Unlock of the bootloader.
$ fastboot-android oem get_identifier_token
...
FAILED (remote: unknown command)
All attempts to use fastboot to unlock the device have met with this error.
It will fastboot reboot, but nothing else. I have a feeling something like the fastboot DirtyCow Exploit will be needed.

Hello,
I can't unlock OEM via the switch at the developer option. It seems open, but when I open fastboot and write fastboot oem device-info , it seems locked.
It seems like the switch has no effect on locking / unlocking OEM
I can't also unlock the OEM with the fastboot commands at the bootloader : fastboot oem unlock-go / fastboot oem unlock / fastboot flashing unlock - with error "remote : OEM unlock not allowed"
Do you have any other ideas?
Heyyo, hmm super weird! Have you tried updating your EUI ROM in case it has some gremlins in it? I was able to unlock mine via developer options.
If you're unable to upgrade EUI I'd recommend a factory reset and try again since unlocking generally wipes out the data partition.

Yes, super weird indeed. I have done a factory reset several times, but the status doesn't change. Everyone has managed it either via developer options or fastboot command. I wonder if there is another alternative doing this. I believe i cant write on to the recovery partition because of it.

That is true. Bootloader must be unlocked in order to flash to recovery.
Just to be safe please read and follow this guide as it is exactly what I did on my Le Max 2

Addendum: I was just talking with someone about this very subject and he got the same result after using SP Flash Tool: Screwed up IMEI info due to corruption of the NVRAM.
If you really don't want to use SP Flash, root, install Mobile Uncle Tools, and flash using that.
how to root vivo Y17 android 9. I have done a variety of ways. but nothing worked
help me master
I have vivo y17 also
I tried to unlock bootloader using this codes:
fastboot oem unlock
fastboot oem unlock-go
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot bbk vivo_bsp unlock_vivo
Bootloader still locked, so no point of unlocking bootloader
I have theory, might not true, if you install the stock rom of the vivo (yours) and modify some files
Then you manual wipe data, and manual install software that has been modified
I not yet tried that yet
I also have vivo y17 1902
I also try everything from fastboot to every tool to unlock bootloader (fast boot commands also)
Nothing work for me
I think it not working because get_unlock_ability is set to 0 by manufacturer and Turning on OEM unlock will not make get_unlock_ability to 1 and it's because manufacturer is permanently lock bootloader.
I have idea we can just replace stock recovery from firmware to custom recovery (twrp) simple then we don't even need to unlock bootloader and we can flash magick .

Hello,
I just received this weird phone I never heard or seen before and I need to root it. I'm afraid to start doing anything because I don't know if I will be able to flash back stock image (let alone find it) if anything goes south. Has anyone successfully tinkered their phone?
Yes. Managed to unlock and root mine yesterday, but with some caveats.
Some of the commands are different.
fastboot oem nubia_unlock NUBIA_NX619J
Is the command to start the bootloader unlock in Fastboot mode.
Then you can do
fastboot flashing unlock
To fully unlock the bootloader.
It appears you have to do the fastboot flashing unlock part each time in fastboot mode.
I flashed the boot.img modified with Magisk, had to reboot into fastboot again and redo flashing unlock before I could boot with my modified boot image. Everything since worked as expected.
One benefit to the Red Magic Mars is that it has an actual recovery partition and does not use the A/B slot partitioning system that so complicates other devices. So as long as you leave the recovery partition alone, you will be able to restore to stock using a USB C thumbdrive with the image file on it.
Hi, so several months ago i installed MIUI 12 weekly to my Xiaomi Mi A3, and now I wanted to upgrade to the stable release. When i was flashing a boot image file, after restart, my twrp dissapear. I tried to flash the rom using Mi Flash on PC, but i touched the cable and the phone disconnected, locking the bootloader in the process. I have no OS, my bootloader is locked. Is my phone truly dead?
I also forgot to uninstall Magisk root from my phone, so it's my full mistake. adb doesn't recognize my phone. I can only turn on the phone, leave it on boot until the battery drains, or the fastboot. Is there any chances that I can save my phone?

I can't. It says i cannot flash while in Lock State. Basically i can't do anything without unlocked bootloader.
well unlock it, you have 2 comands to put.
fastboot flashing unlock
fastboot flashing unlock_critical
FAILED (remote: Token Verify Failed, Reboot the device) after i used the commands you told me.
What should I do next?
And Mi Unlock tool can't unlock the device, because I need to change some settings in Developer Options, and I have no rom.
did you try switching slots?
fastboot getvar current-slot
Getvar Variable not found
f###,
then only some recovery option with
mi tools.
Download mi a3 platform tool file then download fastboot and fastboot unlock critical file paste these both in platform tool folder then plug device through fastboot to pc then first click on fastboot unlock and then fastboot unlocking critical it will be unlocked then install the rom through mi flash
