Hey there,
I wanted to install twrp on my google nexus 5x.
Therefore I've unlocked the bootloader, entered fastboot mode and flashed the new recovery file.
I did this with adb fastboot tool.
No errors occured during the process, but after restarting the bootloader and entering the recovery mode, twr opens for a few seconds
and then gets closed again. Now I get an errormessage everytime (device software can't be checked... please lock bootloader) and I'm unable to do anything in the twr menu because it keeps getting closed
over and over again.
Now I can't even start my phone "normally" and can't get a connection with adb (no results when using: adb devices )
Some Bootmenu informations:
FASTBOOT MODE
PRODUCT_NAME - bullhead
.
.
.
SECURE BOOT - enabled
DEVICE STATE - unlocked
Does anyone know how to fix this issue?
Have you tried relocking the bootloader?

Hi all, yesterday I updated the bootloader of my OnePlus X and today I accidentally rebooted it into fastboot mode, when I tried to reboot the device it started a bootloop. Now I can't even boot into recovery but only in fastboot. I also tried to flash TWRP with command prompt but it says that the device isn't unlocked (strange i'm sure it was till yesterday) so I tried to unlock it with "fastboot oem unlock" but it says that oem unlock is disabled. Please help me
To unbrick your phone use this
You can then update to 3.1.3 Stock with the default bootloader.
You need to enable OEM-unlock in the developer-settings else patching the new bootloader may lock it again had the same problem.

Thank you! It worked
Hi,
First I bricked my phone. Then I flashed the official stock rom using the SP Flash Tool. Then I started the phone and went directly to the build number and tapped it 7x. That made me a developer. Next I enabled USB developer options and enabled OEM bootloader unlocking. Then I connect my device to my Windows PC and start adb
Code:
adb reboot bootloader
That brings me into fastboot. There I use this command to unlock my bootloader:
Code:
fastboot oem unlock
After that I have tried two options:
Flashing twrp using
Code:
fastboot flash recovery x12-twrp.img
Which ends in a twrp bootloop. I guess because the cache was not wiped.
Using adb to reboot
Code:
fastboot reboot
. This however starts the rebootprocess and shows the Android man shortly - I guess that is wehere the cache is wiped - but then when I'm in the OS again everything is gone. It's like a factory reset. I can start over again by making myself a developer --> enable USB-developer options and allwo OEM bootlaoder unlock etc.
What am I doing wrong? I want to see the twrp screen on my phone. What should I do?
Many thanks for your help.
I installed the android 10 update bit suddently when i rebooted it got on bootloop. I tried to go recovery and format it but it dodnt worked. Tried using mi flash but nothing happens. There is any way that i can unlock bootloader? (Cant boot and unlock oem)
Use the following codes on the adb after entering fastboot mode
First enter fastboot mode by pressing power and volume down until fastboot mode starts(about 10 sec)
Then enter the code
1) fastboot flashing unlock ( press enter)
2)fastboot --set-active=a (press enter)
Then run mi flash tool. Your phone should start.
Doesn´t work because the phone is locked and i can´t unlock it because don´t boot. That´s the problem.
Claim warranty!

Since your bootloader is locked and this loop occurred while officially updating you could claim the warranty and they will fix your phone for you.
Is it possible to install twrp recovery and root using magisk in this phone or not possible because of mediatek processor?

Orange state in realme 7 when bootloader unlocked but unable to use fastboot.
I have unlocked my realme 7 bootloader with in-depth test built for realme 6 pro. It is working. But now after unlocking the phone factory resets itself and when trying to go into fastboot mode with ADB command ADB reboot bootloader the fastboot verify check fails all the time. So how to go into fastboot mode after bootloader unlock. This issue never happened when I start in-depth test after permissions. It's very strange that even after unlocking the phone is not booting into fastboot mode while giving error in verification. Guys can anyone knows how to solve this. Please reply asap.

I think your adb driver not working please install adb driver reinstall and verfiy fails problem solve, thanks
No no adb driver is working and tested on other devices. I think the problem is with smartphone serial key ( It shows serial key mismatch and therefore fastboot unlock verify fail in fastboot mode).
To Root you phone:-
Download your device boot image > download magisk manager > patch your device boot image > go to fastboot mode > type in command >fastboot --disable-verity--disable-verification > flash vbmeta (fastboot flash vbmeta (put your vbmeta path here) > flash magisk patched image (fastboot flash boot (put your patched file path here) now reboot your phone it will be rooted if on First boot it didn't then reboot your device
Hello I have a xiaomi mi mix 3 5g that I never removed the bootloader on, as it had the stock EU firmware on. It has recently been updated to to MIUI12. however the battery went low and went all weird and now constantly reboots.
I can get to fastboot by holding down the power and volume down, I have also tried a wipe device by holding down the power and up. From what I have read I i cant re-install fastboot firmware without and unlocked bootloader. (can someone confirm that this is correct) as its not clear.
***I have now confirmed this I have tried to install firmware using xiaomi flash tool and fails with the following
"Error: erasing boot Failed remote erase is not allowed in locked state. so this confirms it.
Also I cant unlock the bootloader as it wont boot. Does any body have any idea of what I can do with this phone? any help would be apprciated
thanks
The error I get when trying the mi unlock tool
Couldn't Unlock
Please add your account in MIUI;s Settings > Developer options > Mi Unlock Status
Seems the update miserably failed, Android OS got corrupted. My suggestion: Re-flash phone's Stock ROM ( phone's battery should be fully charged ! ).
To keep you updated:
FASTBOOT is a program used to manipulate ( list, install, erase ) the non-volatile memory such as flash filesystem partitions on devices that adhere to the fastboot protocol, via a USB connection from a host computer. It requires that the device be started in a boot loader mode ( AKA fastboot mode ) with the fastboot protocol enabled.
Take note that fastboot ( the fastboot daemon ) is integral part of phone's bootloader.

How do I re-flash stock rom when the bootlloader is not unlocked.
I have already tried Xiaomi's flash tool and it when flashing the stock ROM and get the following error
"Error: erasing boot Failed remote erase is not allowed in locked state"
Are there any methods of flashing a stock rom with a locked bootloader ?

I have already tried that method When I flash using the flash tool I get the error "Error: erasing boot Failed remote erase is not allowed in locked state" My bootloader is not unlocked is this method supposed to be work with a locked bootloader. Bit of chicken and egg situation. I cant unlock the bootloader as I cant boot the device and I cant reflash software as I don't have an unlocked bootloader.
AFAIK you always are allowed to flash an original firmware image without unlocking the phone's bootloader.
If you can access the device by means of ADB try to flash the Stock ROM via ADB:
Code:
adb devices
adb reboot sideload
adb sideload <LOCATION_OF_STOCK_ROM_ZIP_FILE_HERE>
C:\adb>adb devices
List of devices attached
f625af1 sideload
C:\adb>adb sideload miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip
loading: 'miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip'
* cannot read 'miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip' *
@sivhead
Try this:
Rename the file to rom.zip and then start "adb sideload rom.zip"

I also thought its worth mentioning that I have never registered the device with mi connect
Also enable usb debugging is not enabled.
aqnd THe bootloader is locked .
Man I wish I would have unlocked the bootloader when I got it and put a custom rom on. then I wouldnt be in this situation. how ironic that I wanted to keep it stock
so I am at a loose end
