First go to settings and then open develop option please on oem and go to download mode
Download mode
Vol down or vol up and connect usb cable with computer
Download mode show unlock mode then long press
It shows that if you unlock bootloader for reset devise
Then your device is reset
Now your device of bootloader is unlock :laugh:
The OEM Unlock option does not appear on my phone. Mobile is in "normal" mode, I have more than 7 days of uptime, the option simply does not appear. I've tried all the tricks I've seen on the internet. SM-A305GT. Would anyone have any solution?

Hi, Im kinda new to this bootloader thingy. What happen is, i updated the razer phone 2 to Pie, but notice wifi and sim card cant be detect. Even factory reset fails. So i thought of flashing new image on it. KINDA easy on my oneplus, but im not sure where I gone wrong on this razer phone 2, i accidentally unlock the bootloader. NOW the problem is HOW to relock it back? i been follow all youtube and guides all over the place but still fails.
The state of device atm, cannot be boot into Download Mode. Everytime I plug in usb c from Windows, it will boot into unlock bootloader warning page, and continue boot into the homescreen. testing the adbtools, fastboot also to no avail. Can anyone help and guide me how to relocking it back? Maybe i type wrongly on cmd or maybe other android steps not similar to razer one etc....:crying:help much appreciated.
Hold volume down while turning on. Then fastboot flashing lock.
the stock usb doesnt send things correctly in BL mode, https://www.amazon.com/Blackweb-3-Foot-Charge-Cable-Connector/dp/B07SG7P3KZ/ worked for me. with the correct usb cable you should be able to perform the lock commands correctly. can you give us more detail of what you tried on this phone so we know if we need to provide you additional information?

"Locking the Bootloader
Locking the bootloader is recommended for security reasons. Some applications will not work with an unlocked bootloader.
Start the Phone in Download Mode with one of the following methods:
Using the adb tool: With the Phone powered on, execute: adb reboot bootloader Enter Download Mode:
Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
Lock the critical partitions of the Bootloader first by running this command: fastboot flashing lock_critical
Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot."
I can't seem to enter download mode. All I have is fastboot mode and the option to either reboot, close the phone or enter recovery mode. I would really like to lock the bootloader, but I can't seem to be able to detect my phone on my PC even though I installed the fastboot driver.

You must use a USB 2.0 port. The RP2 isn't detected by fastboot when connected to a 3/3.1 port.

You need to go into your device manager and select [ android bootloader interface ] while in fastboot
I really need to enter fastboot mode on my zuk, but your screen is burned out so I can't enter developer options to activate usb debugging and perform the "adb reboot bootloader", I would like to know if it is possible to enter fastboot mode through of combinations of physical buttons. My zuk has a blocked bootloader!
As far es I know you need a unlocked bootloader and usb debugging has to be activated.
Why do you need to get into fastboot? If ur screen is no more...

Hi everyone, i am trying to root a poco m3 pro. But I get stuck with the mi unlock app on my computer. It tells me to turn off the phone and enter the bootloader by pressing volume down+power. The phone is in fastboot mode, but my computer doesn't see it. I tried different usb ports, and different cables. I checked if I had developer options on, the bootloader is already on unlock, the usb debug is on; I can't find the mistake. Is someone so kind to try and help me find the problem?
for unlock bootloader u must wait one week from request
oh. Is that the problem? I am not so sure that i have requested the bootloader unlock. how can I check?
Don't do it over and over again,
OEM unlocking for MIUI is kind of dumb. First you need to disable wifi, go to the dev menu, OEM unlocking, add your account, then wait 7 days (168 hours)
