i did it for training, but then i tested fastboot device-info and it showed locked.

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

Unable to unlock boot-loader and root Micromax Canvas A1 AQ4501

Hi,
I have Micromax Canvas A1 AQ4501 which comes under Android One. It’s upgraded to Android 6.0.1.
I tried to unlock its boot-loader but it’s not successful.
I did
• adb reboot bootloader
• adb devices (it shows device.)
• fastboot oem unlock (after this command its stuck on 'waiting for device')
• fastboot flash recovery recovery.img (after this command its stuck on 'waiting for device')
I changed USB cable and plugged it in another port but no changes.
I tried to root it using Kingo Root from PC. After 15 to 16%, it says, failed.
Please help me to fix this issue.
Regards
Ugn10

Do you guys have OEM Unlock on dev mode?

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...

Fix bootloader message

For some reason, few cases present the generic and ugly message of bootloader unlocked, and not the original of Xiaomi and here I have the solution.
If you have a uggly bootloader message, like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And you want the common image with a padlock, similar to this (but not the same):
You only need follow the next simple instructions, you have 2 ways to do.
First way - ADB Recommended
1. Install or download adb from here.
2. Conect your phone on fastboot mode.
3. Download and extract the attachment file on the same folder than adb.
4. In the same folder of adb, open a terminal (cmd, powershell) and type: "fastboot flash logo logo.img" (without quotation marks obviously).
Second way - TWRP CN
1. You need the TWRP CN (not multilanguage).
2. Download the attachment file, unzip and put on your internal memory.
3. Reboot on TWRP.
4 Choose "IMG" on the install section.
5. Select the logo.img and fhash.
I hope it will be you useful.

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

Help! Device not detected in fastboot mode

Hello!
I have a Allview X3 Soul (clone of Gionee S6)
GsmArena link : https://www.gsmarena.com/allview_x3_soul-7913.php
So, i managed to get it in fastboot mode through adb. The phone screen shows this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So it says that fastboot AUTOMATICALLY turns off to keep the phone safe.
PC doesn't detect it in fastboot, only adb
I have rooted it and then unrooted with KingRoot (NOT KingoRoot) 1 year ago, and after that wireless connections stopped (wifi, cellular data, calls and bluetooth), I couldn't install some apps.
3 months later I tried rooting with Magisk Manager (bad idea, i didn't have twrp or unlocked the bootloader). Same thing happened as last time, adding that the wallpaper became blank black
Anybody knows how to unlock bootloader through adb or to enable fastboot mode through adb?
EDIT 1
Performed a Hard Reset, same results
You do not have to use fastboot to flash TWRP recovery ..or any new rom .. use sp flash tool to flash the orginal firmware
