after i typed the last command (fastboot reboot )the phone wont start up again its like dead no light or anything is showing i connect it to a pc i hear the usb sound but nothing appear
i tried typing adb devices but nothing is showing
is the rom i install is bad or somthing and how do i fix it and turn it on at least into fastboot
Unsuccessful rebooting 7+ times was supposed to switch phone to use another of A/B slots with previously booting system.
If phone is unlocked, u can try to switch A/B slots via fastboot or temporary booting into TWRP.
If phone is locked, search for TestPont/EDL flashing guide.

I'm stuck at an issue that I've never seen before and need some assistance. I flashed invictrix 8.1.0 not to long ago and then installed an updated version of the rom through the rom's updater. It went through the automated flashing of the updated version and now I'm stuck in a recovery that seems to be stock, but it's not the stock version I am accustomed to seeing. I can not do anything in this recovery. I have used adb to do things before, but now adb and fastboot seem to get stuck at waiting for device errors or error:device not found even though adb devices and fastboot devices brings up the phone being connected. I now can no longer boot into the phone as I did a hard reset while my phone was operational.
Have you tried booting straight into fastboot mode by holding down Power+Vol Up until it reboots? And then see if you can use fastboot on your PC to flash TWRP again.
Also, all those error messages. Did you at some point reformat the cache partition as f2fs? It's supposed to be ext4..
I can boot into fastboot. The computer recognizes the phone through fastboot devices and adb devices. However, issuing a command through fastboot results in a waiting for device message. Maybe I need to find a more suitable adb. The one I’ve been using is the 15 second adb that only installs the google driver and the adb. I never formatted anything. I’m not sure what to do at this point.
I would use an unbrick guide and start from scratch.
Is there one you'd recommend ? I'm using this one :
https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306
Yes, I also used it in the past and everything was ok.
So i followed this guide to root my Mi A2 "theandroidsoul (insert dot here) com/xiaomi-mi-a2-root/"
It went all fine but the phone was still not rooted. So i thought maybe get the newest Magisk.zip wich i put on the phone.
So I went back to step 11. to install the new version with TWRP but it didnt go to TWRP although i held the volume up butten and then used the command "fastboot reboot" and then it weent into bootloop
so i Guess i am stuck on my Partition A (in my case) where i installed TWRP but i cant shut the phone dont to get into fastboot and ADB says Error: no device Found".
I Need Help plssss :crying:
If you cant go to fastboot then you need open up phone and use testpoint to force edl mode
But before that hold volume down and power for 10-15 sec to force fastboot
The battery is drained now, i tried to plug it in to the wall and boot into fastboot right away, i saw the fastboot screen for a splitsec but it cut off because it had not enough charge, so i left it plugged in and tried to go to fastboot constantly till the phone had enough charge to hold the boot, i was in fastboot for about 1 minute or so (my plan was to charge it in fastboot mode, leave it like that and then go to the pc to change the active partition back, but the pc didnt recognise the phone) but after that it startet bootlooping again while it was in fastboot.
Could i try to got to TWRP with "volume up + power button" ? and change the active partition in there?

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
Hi I have a problem where my pc does not detect my unlocked device in fastboot. This is a problem because I tried to update from global V10.3.3.0 to miui 11 but that did not work probably because there is not the right recovery on the device. So I can not get into the recovery and I can not get into the system this would of course be no problem because I can get into fastboot but my computer wont detect my device. How can I get my 9t pro to be detected in fastboot?
My device is unlocked. I did all that some time ago and it says so when I try to boot into system or recovery.
USB debugging is on. Idk if that is still there because I did try to update the system to miui11 but it was not detecting my phone in fastboot even before I did that update.
When I connected my phone to my computer when the system still worked I could use "adb devices" and that worked
I could also transfer files and stuff when my phone was connected to my laptop
So only when in fastboot my unlocked device is not detected if it was I could get back up there.
I really hope that this is some driver problem or something. Please help
Edit:
So at this point magically the system worked again! But I still can not use fastboot
I seem to have this problem:

SOLVED
Hi there.
I had my couple's mobile rooted with Magisk and MIUI Global 10.3. Once wanted to update twrp and the issues began. Actually the mobile isn't rooted but with unlocked bootloader, apparently.
I list the issues down below:
1) Trying to install twrp with fastboot by CMD, pressing enter after the command the cursor just blinks and nothing happens. At first it showed "waiting for device", so I installed adb drivers and the mobile appeared in Device Manager. It run once up to "sending 'recovery'" but not farther. The mobile was connected in fastboot mode indeed as well as in usb debugging but couldn't activate oem unlock as it stated it as unlocked and the option was dimmed.
2) Tried to unlock the mobile with Miflash_unlock and the phone was recognized, but the tool checked the device up to 50% and then showed that it Couldn't verify the device.
3) Then I tried to make a backup of the user data and doing a Hard Reset from settings. It went forward up to reboot, so I did, then it entered in fastboot mode for a few seconds and it powered off. Rebooted the phone and it was up and running as if nothing happened. So I cannot make a hard reset.
4) I can't enter the recovery too. If pressing volume - and power on it enters in fastboot mode. With volume + and power on it does the same With recovery enter tools isn't possible either. It seems as it's been corrupted.
5) I've just tried to flash the Global_8.0 rom with MiFlash 2019.12.6.0 and on the progress line it says "echo Mismatching image and device" How? I'm sure its a Mi Mix 2 'chiron' Rom, so... Anyway, I start to flash and the tool seems to progress but it never ends. So I disconnect the phone, reboot, and it keeps untouched running as before, OMG
6) On top of that I can't update android by OTA, as it gets downloaded, then reboot, then enters fastboot mode and after few seconds it powers off as before, and powering it on afterwards shows that it couldn't be updated
So I don't know what to do next. However, the mobile runs apparently ok.
May someone lend me a hand, please?
Thank you.
SOLVED: The Xiaomi Mi MIX 2 is up and running with the last firmware installed. The issue was that, as I build a new PC lately, I connected the phone in fastboot mode to the front USB ports, which are 3.0 version, and you need a 2.0 USB port at most, causing errors in MiUnlock and MiFlash.
