Greetings smart people,
I just got this redmi9 from my brother. Phone is usable at the moment.
I want to:
1. Unlock bootloader
2. Flash Twrp + rom
My problem is i cant get the phone to enter fastboot mode (bootloader hasn't been unlocked yet). While the phone turned off, holding voldown + power button, will not go into fastboot, it will just reboot back to miui.
Is this softbricked or something?
Please and TQ.
Could be the key is broken.
Enable usb debugging and run command:
Code:
adb reboot-bootloader
Return to system:
Code:
fastboot reboot

I've had this happen on my xiaomi redmi note 4, and it was just a button issue, you should try this suggestion, because I managed to log in this way.

I have a G4 h811
it respond to ADB commands but not to fastboot commands
i get waiting for device message
so i tried power plus volume up
nothing...
power plus volume down
nothing...
if i type adb devices command
i can see my h811 as a valid device so adb works
but
the only thing that kind of works for the fastboot is to get in to adb and send this command
adb reboot bootlader
phone reboots and get the LG life is good logo and on th etop left i get little fonts
that says
******************
Welcome to Fastboot mode for OEM bootlader unlock
* Quick guidance
1) how to unlock : fastboot oem unlock
****************************
Si when i send the command
fastboot oem unlock
i get
<waiting for device>
nothing happens
and my phone wont turn off if i press the power button for more than 10 seconds
i need to remove battery to turn off
reinstall battery and boot up normally with the LG then tmobile logos

Are you using a usb 2.0 or 3.0 port? You should use a 2.0 port.
Also try disabling windows 10 driver signature enforcement.
SOLVED..
I was on a win7 computer... never worked somehow
switched to a Win10
and worked like a charm...
twrp installed and rooted
using this guide
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
My screen is dead. I want to get into fastboot to use "adb shell twrp decrypt mypassword" to be able to pull a backup. BUT:
How do I get in fastboot just with the hardware keys?
Out of 900tries my phone will be listed as "offline" in "adb devices" atleast 899times :/
I only managed once to get into fastboot from where I booted into twrp.. then it was listed in "recovery" state for a few seconds and then "offline" again
Thanks !
Hi.
If you boot into bootloader you can't issue adb commands, only fastboot commands.
Anyway, to boot the N6 in bootloader:
Device powered off, press volume down and power buttons at the same time for a few seconds should get you in the bootloader. You should see your N6 in device manager showing up if you can't see it, since your screen is broken.

Thank you ! That worked.. I am in fastboot..
I then tried "fastboot boot recovery-twrp.img"... which booted the recovery.img... and then I am again in "offline" when running "adb devices".
Any ideas? :/
Not sure... But if your recovery s password protected, I don't think you can use adb until it's decrypted. I don't have a password on recovery and never had to use adb there... Sorry.

Was able so solve it:
1. Power Off
2. Boot into fastboot with Power Button + Volume Down pressed
3. Connect to laptop/computer
4. Check if device is here with "fastboot devices"
5. Download latest twrp recovery on your laptop/computer
6. Boot the recovery with "fastboot boot /home/username/downloads/twrp.img
7. Check if recovery was booted correctly with "adb devices"
8. Run the following adb command: "adb shell twrp decrypt mypasswordhere" .. if the password is a pattern, then use the "numbers" e.g. if it is an "L" pattern (from top to bottom) then it would be: 14789
9. Download files with "adb pull /sdcard/ /home/username/Downloads/
Glad you got it sorted! :good:
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.

I tried this, but to no avail. I tried with 2 cables I had and it keeps telling me < waiting for device > when I enter this command; fastboot flashing lock_critical

You need to go into your device manager and select [ android bootloader interface ] while in fastboot

ADB installed and USB debugging activated?
Then, when attached to a PC, try:
1. adb devices (will show if device is recognised) if yes->
2. adb reboot fastboot
tried that, fastboot mode appear for a moment, disappear then phone start normally

Sorry mate, have no further ideas.
Hello
I have a clean untouched redmi9 MIUI global 12.5.5 android 11
I have not even used it before.
I tried to enter fastboot mode by enabling developer options oem unlocking
also USB debugging on
Then I power off and I press volume down + power key
Phone just vibrates and restarts does not enter fastboot. If I quickly remove hands while vibrating it gets stuck on vibrating until i hard press power again. I can never enter fastboot mode even though I tried a lot of times. I downloaded the ADB tools and used .\adb.exe reboot bootloader. Phone vibrates for around 6-7s then restarts.
How do I enter fastboot mode it should not be this hard!
Hi
You are using the wrong command
type
adb reboot bootloder
