Unlike in some other devices, you don't necessarily need to unlock the bootloader to flash a custom ROM to your Mediatek (MTK), Spreadtrum (SPD) Android phone. You don't even need bootloader (fastboot) to flash a custom recovery since Mediatek has SP Flash tool and Spreadtrum has Research / Upgrade download tool amidst several Chinese boxes. There are however certain scenarios where fastboot is the only feasible way to get a custom recovery loaded to your device from which you can then root, backup or install a custom ROM. This guide will explain how to unlock the Bootloader on a Mediatek (MTK), Spreadtrum (SPD) or Qualcomm (QLM) Android phone, an important prerequisite for flashing a custom recovery via fastboot.

Requirements

• Setup ADB-Fastboot on your PC. For Spreadtrum devices, follow this guide (in order to enable adb detect your device)
  
• Enable USB Debugging and OEM Unlocking (if available)

How to unlock a Mediatek, Spreadtrum or Qualcomm Android phone's Bootloader via fastboot

[QUESTION] How To Unlock Bootloader When Stuck In Fastboot ...

Follow the steps below to unlock the Bootloader of an Android device

See the video tutorial below or @ https://youtu.be/DL5NMR-n4_Q

1. Open the adb folder
   
2. Hold Shift (on the keyboard) then right-click on a blank space in the folder > Select Open Command window here
   
3. Command prompt screen (adb) should now be open
   
4. Connect the phone to PC (via USB cord) while ON then run the command below (by 'run', I mean type then press Enter
   
   adb devices
   
   
5. If you've setup everything right, the device should get detected under List of devices attached
   
6. Run the command below to get the phone into Bootloader (fastboot)
   
   adb reboot-bootloader
   
   
7. The phone should now boot into fastboot
   
8. In fastboot, test detection / connection to the device using
   
   fastboot devices
   
   
9. If fastboot is set up right, you should see its ID printed out
   
10. Now, check the phone's Bootloader status using either of the two commands below (if its locked or unlocked)
    
    fastboot oem device-info
fastboot getvar unlocked
    
    
    1. If you use the fastboot oem device-info command and the result is false then your bootloader is locked but if the result is true then the bootloader is unlocked
       
    2. If you use the fastboot getvar unlocked command and the result is no then your bootloader is locked but if the result is yes then the bootloader is unlocked
       
    
    
11. If you've confirmed your bootloader is locked, then run the command below to unlock Bootloader
    
    fastboot oem unlock
    
    
12. If that doesn't work then try either of the two commands below
    
    fastboot oem unlock-go
fastboot flashing unlock
    
    
13. Note that some devices require you to also run
    
    fastboot flashing unlock_critical
    
    
14. You should get a prompt (on the phone) asking you to press Volume up to confirm or Volume down to cancel. Press Volume up on the phone (for some phones its actually the opposite; Volume down would confirm while up would cancel or do nothing)
    
15. Once Bootloader is unlocked, reboot the phone using
    
    fastboot reboot
    
    
16. The phone might take a while to boot up (since its a first boot) so be patient
    

Important Notice

• This guide isn't guaranteed to work on all (Mediatek, Spreadtrum, Qualcomm, Exynos, Hisilicon, Intel etc) Android phones
  
• Ensure to backup your important stuff because unlocking your Bootloader wipes your phone's data (/userdata)
  
• Unlocking the bootloader bricks some devices so ensure to relock or flash the firmware if you find yourself in such a situation
  
• If you successfully installed ADB / fastboot and your device still isn't detect then its most likely due to old ADB, fix it using the guide here
