And open the phone itself
Can I ask you how I know the bot loader is opened؟
I may have missed it I I I don't know
Wait for a response from you, sorry if I ask too much

That means your PC isn't installing fastboot drivers.
You have to install it manually. Just download below flashtool (also you'll need it later in final installation) (link below)
http://d-h.st/Kb8
Install it in your default PC drive.
Navigate to;
flashtool folder (default drive) > drivers > flashtool driver.exe > double click on it > next > fastboot drivers (at bottom of the list) install it and now connect your phone in fastboot mode.
Now follow and Complete popups for fastboot.
(If there's popup for MTP drivers, just cancel it)
After installation is finished Disconnect device and connect again in fastboot mode.
(VolUP and then connect USB )
If above process fails, let me know

If you can't get into fastboot mode (blue LED appears for few second and then continues charging with red LED) then just follow steps written in above post.

Okay! So you are at the first step (UBL)
Answer few questions;
1. Which windows version are you using?
2. Do your phone successfully stay in fastboot mode?
(Power off > press volUP > connecting USB )
[Blue LED appears]
3. Did you get your Unlocking Bootloader Code from Sony site?
PS: when you successfully typed those three commands, your phone will auto reboot and bootloader will be unlocked.
To confirm that your bootloader is unlocked, you'll notice that your phone is factory resetted.
Also type *#*#7378423#*#* in dialer and find bootloader unlock status.

2-He succeeded in entering the fast mode and the blue led's
3-Yes were already official Sony website code to unpack the boot loader
The command has already provided written

But the device did not restart itself and the system was as
Not a factory as I
And put the code that you wrote you this:*#*#7378423#*#*

If you have successfully performed every step till (7) and rebooted into system (7th step) , you shouldn't get any problem.
To enter into TWRP, reboot your device and when you see magenta LED press volUP button for couple of times, you'll successfully enter into TWRP.

Nope! You can't skip bootloader.
There are some ROMs available that can be flashed with locked bootloader.
Soft bricking is the main drawback of flashing ROM on locked bootloader. Usually it happens once.
PS: I can't provide pics of steps. Its because I already unlocked my bootloader and I can't do it again.
Also I don't have another ACRO S.
I suggest you to unlock your bootloader using other PC to avoid bricking.

Hello,
I'm planning to buy this device, specifically the XT1684 or XT1685 variant. Are these specfic variants supported and are there any culprits I should be aware of? For example, is there a possibility of me being locked out like with LG's G/V series devices? Or is the bootloader unlock procedure completely smooth?

thanks for the guide. I have just unlocked it.
Any guide to root it?

Can't say for sure since I don't own the device, but I guess flashing the SuperSU zip in TWRP will do (when the TWRP for this device releases, that is).

as usually unlock bootloader void the warranty, right???

There is a thread specific to this here... Seems there was a glitch and Moto was issuing codes for a few days until it was caught and fixed.

The instructions worked for me, allowing to unlock the bootloader. Device was a reconditioned moto g5 plus (XT1685) bought from amazon (not an "amazon exclusive", the international version).

Fastboot is not working on my G5 Plus
The adb devices show my device before reboot:
C:\Windows\system32>adb devices
List of devices attached
0036349461 device
But when I execute the command "adb reboot bootloader" my mobile restart on fastboot mode and after it the commands like "fastboot devices" or "fastboot oem get_unlock_data" doesn't response...

[SOLVED]There is no recovery mode in LG K420n?

I tried various buttons combinations but none of them worked. I can only enter something called 'emergency mode'.
Is this means that I can't install TWRP?
Also I have question how to enter fastboot and download mode.

- TWRP: use vineethp guide, or flash it automatically with Cris Kernel (root requiered)
- FastBoot: not officially unlocked, but you can make it available by adb shell (I think)
- Download Mode: while device is off, press and hold volume up key, then plug the usb cable to your PC and then to the phone, after that the phone will startup in download mode.
Note: You can also enable/install/access to fastboot and twrp from just download mode, but for this will be necessary to use some adb shell commands.

Moto G5 (Cedric) bootloader won't unlock. Adb says unlocked

Hi. I have unlocked several devices before and only this phone is getting on my nerves. I have followed every steps exatcly as on forums to unlock my bootloader. On adb it says "Done. Phone will restart now". After this the phone reboots back to fastboot and "Oem locked" status is still there (Phone gets wiped after this process). I have tried to install twrp but it just wont due to locked bootloader. In adb it says "Preflash validation failed" and on device bootloader logs it says "Recovery size misatch". What can I do to force unlock its bootloader?
Fyi: I have tried updating android versions (Noughat to Oreo) and several Twrp versions yet it wouldn't work

I gave you that link because there are many unofficial ones around. Also, only try the latest official one now. But it seems like your bootloader is still locked. Is your G5 the Amazon version? That cannot be unlocked.

Your device is oem locked
Open settings
Goto about phone (or system then about phone)
Tap on build number until it says you're a developer
Go back to settings screen and then select the new available developer options menu
Make sure you have enabled allow oem unlock (if available)
Also enable USB debugging
When it comes to unlock string make sure you copy and paste it into a text document and then remove all the line breaks so the string is on one long continuous line
Follow the steps on the Motorola unlock website to get your unlock code - scroll to the bottom and click next and sign into your Motorola account

Software channel is "reteu" on mine. I can't screencast right now but I can assure you that there's no error message anywhere while unlocking. On cmd it says Done. On phone it just restarts back to bootloader. No new logs are there. And there should be an error message after unlocking right? Well that doesn't appear as well.

Now do the the following
Copy and paste this line exactly - do not type it to avoid typos eg putting 0 instead of O
Code:
fastboot oem unlock GOSZ2EGP7B7G3Z5NQLUN

As long as it's entered correctly it should unlock
Apart from trying a different USB cable, not using any USB hubs or trying it on a different pc there's nothing else I can suggest as that is the unlock code from Motorola for the device unlock data
You could try flashing different firmware and then trying to unlock it

Question How do I replace stock recovery with custom one?

Can anyone please share a solution to replace my c21's stock recovery with a custom one?
Actually, I hate bloatware, and I want to root my C21 to get rid of them all!

At this stage until realme releases the deep testing app it's hard to do
I am looking into a way and will let you know if I manage to do it

i not see any custom roms

It's a clickbait article.
Infact we cant even boot into fastboot mode without unlocking bootloader, and there is no "depth test" app for realme C21

You can boot into fastboot mode of C21 by executing this command through PC or a laptop.
1)Download Adb and fastboot drivers. (Skip if done)
2)Go to your device and enable usb debugging.
Then do this-
Connect your phone to your computer using a USB cable.
Open CMD/Powershell on your computer.
Run the following command to make sure the computer recognizes your Realme C21:adb devices
Now you have two choices again:
If you want to boot your Realme C21 into Fastboot Mode, use the following command: adb reboot bootloader
If you want to boot your Realme C21 into Recovery Mode, use the following command: adb reboot recovery
Once you run the following commands, your Realme C21 will turn off and go into Fastboot/Recovery Mode. That is all you have to do. Now you can flash factory images, custom ROMs, unlock the bootloader, and much more.

I don't know what you are striving for.
If I hadn't tried it, I wouldn't have said it wouldn't happen like this.
Finally, my device's bootloader is already unlocked by me and I've been using it as rooted for a month already.

This method doesn't work on the C21Y, for some reason I couldn't get the "mtkutil" to recognize the device in any mode.
How did you do it?

Unplug USB cable, hold all 3 keys at the same time
While holding keys, plug usb cable when your device screen off.
Keep holding keys untill mtkclient detect your device.
Tip: Use a linux distro if mtkclient cant detect your device on windows.
Edit: Unfortunately, Realme C21Y not has same SOC as C21,
It has a Unisoc processor, mtkclient works with mediatek chipsets only.
