I have a little isssue with the bootloader...
Sometime ago, i have unlock the bootloader easily, no problems.
But now, i have checked if it is unlocked, and it is no longer
So i have tried to re-unlock it, and fastboot display that's okay and my phone reboot into recovery.
I have rebooted it into bootloader mode, typed "fastboot oem device-info" and nobody is true !
What do you think about this ?
Ps: Sorry for bad english
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.
Thanks for your reply, but it doesn't work
I have only my old recovery (who is twrp in is latest version, no problems with that )
But suddenly i wondere if unlocked bootlooder is useful if i have already an recovery
Finally, i have followed the mega unbrick guide.
Hi guys .
I tried many method to install twrp but cmd always say < waiting for device > although i unlocked bootloader , check usb debugging and oem . Please help me
Solved: Just change PC
Did you boot into fastboot? If so try command "fastboot devices" and check if your device shows up.
Try this method also..

Does enabling OEM Unlock from developer options (Android 5.1.1) unlocks the bootloader?
If yes then can I directly flash a custom recovery after enabling OEM Unlock?

No, it only gives you permission to unlock bootloader.
You will need to unlock bootloader using adb.
Try this,
Download adb and Koush Universal adb driver and install them on ur pc, always install the driver first and don't install the drivers adb setup asks u to install.
Run command prompt as administrator.
Open the folder in c drive where adb is installed, u can use file explorer for this.
Press Shift+right click and select open command window here.
Enable USB debugging on your phone and connect it to the pc by a USB cord.
Enter command "adb devices" without quotation marks.
If it shows some device connected, only then proceed further.
Enter command " adb reboot bootloader"
Enter command " fastboot devices", if it shows some device to be connected, only then proceed further.
Enter command " fastboot oem unlock".
Ur phone may then ask for final confirmation on the phone screen, select yes.
When procedure completes, type "fastboot reboot" and your phone will reboot normally.

thnx for the reply augustonandro ! but i think im doing something wrong , whenever i type the command adb reboot bootloader my device(Galaxy J200G) restarts instead of rebooting to bootloader . So I just went to my stock recovery and chose option "reboot to bootloader" but still it restarted instead of rebooting to bootloader.
Am I doing something wrong?

guys i just found out this thread:https://forum.xda-developers.com/galaxy-j2/development/dev-samsung-galaxy-j2-lte-t3258147 and it says that just enable OEM Unlock and your bootloader will be unlocked. Is it true?
No, as explained above. That just allows the bootloader to be unlocked via ADB/fastboot (unless the bootloader is locked down like many ZTE phones).
Have you tried "adb reboot-bootloader"?

Hello,
I accidentally flashed a Stratos firmware on my Amazfit Pace 1. Blame on me !
But since I cannot unbrick it.
I can boot in fastboot bootloader thank to thread https://forum.xda-developers.com/smartwatch/other-smartwatches/amazfit-boot-fastboot-directly-t3546829,
but I cannot boot into recovery with command :
> fastboot boot Amazfit-mod-recovery.img
downloading 'boot.img'...
FAILED (remote: ED: The command is not allowed.)
finished. total time: 0.063s
Can anybody provide help ?
Thanks in advance
The error message is because bootloader is locked. If you don't have root access nor unlocked bootloader, I guess the only option is trying to use Ingenic's "cloner" tool to flash the firmware directly (use option 2 instead of 1 to enter "force erase"). You should flash an old firmware with unlocked bootloader first, check if serial number is OK (if now, fix it using the info in the thread about fixing a null SN) then update.
PS: Do NOT enter "force erase" without having everything set up correctly because the watch won't leave this mode until you flash it.

Thanks @IFOm
the problem I have is that the swatch boots, then reboot, and finally fall into error screen. So I have little time to act with adb.

On Windows use:
Code:
adb wait-for-device & adb shell reboot bootloader
and on Linux/macOS:
Code:
adb wait-for-device; adb shell reboot bootloader
and watch will enter fastboot mode as soon as adb is detected (you can type the command and adb will wait for the device, as the words say, then issue the second one).
adb shell does not work, I get following message :
- exec '/system/bin/sh' failed: Exec format error (8) -
using port=5555
enter fastboot using this method https://www.youtube.com/watch?v=ZlXoeq30vM0 and check the correctness of the serial number and the bootloader lock

Your system is messed up... You can go to fastboot mode manually, then try to flash the correct kernel (boot.img) and recovery from fastboot... this my fix your serial number and show locked status as unlocked again. If everything fails, your last resource is the cloner tool I mentioned a few comments before.
