[CLOSED] My BOOTLOADER is locked and I cannot flash firmware - Moto G4 Plus Questions & Answers

Hi, recently I realized that my device has the bootloader locked and I cannot flash the firmware through Fastboot Flash Mode (Secure). When I try to unlock it taking in mind the Motorola site instructions and entering the fastboot oem get_unlock_data command it throws me this error:
(bootloader) Unlock data:
(bootloader) read datablock error
(bootloader) Failed
OKAY [ 0.040s]
finished. total time: 0.041s
I lost my IMEI and I don't know if that's interfering when trying to unlock bootloader. Can someone please tell me what's happening?
Thx for reading.

[SOLVED] Moto G Unlock Bootloader "Password incorrect" ISSUE RESOLVED

Hi guys,
IMPORTANT ***
- THIS TUTORIAL IS ONLY FOR PHONES THAT HAS BEEN UPGRADED TO ANDROID 4.4.4 ONLY DO NOT FLASH IN ANDROID RUNNING 4.4.2 -
I was trying to unlock the bootloader of my Moto G from Boost;
I completed the process according to motorola's website .
And at the moment of running the code | fastboot oem unlock [UNIQUE DEVICE 20 DIGITS KEY] | the result was | "Password Incorrect" | : that was because I had upgraded the Android Version 4.4.2 to 4.4.4 before unlocking the bootloader, There was no way how to fix it. I last the entire day looking for a solution and at the end of the day I found this tutorial provided by Motorola.
AND IT DID WORK FOR ME
Here you have all you need to fix the "PASSWORD INCORRECT" ISSUE:
Download the .zip file on this link
https://forums.motorola.com/files/51c3cbf839/G_4.4.4.BL_Fix.zip
Extract it and you will find two folders, select the one that say | G_4.4.4.BL_Fix | inside you will find different Word files, select the one called READMEFIRST.rtf |That's the motorola tutorial for the Password Incorrect issue|
BEFORE FOLLOWING THAT TUTORIAL FROM MOTOROLA
Make sure you have the files motoboot.img and motoboot_41.5_testdrive.img into the same directory that you're running the adb codes [ in my case it was Platform Tools ]
and as the tutorial says it might give errors as is not identifying the password as correct but just ignore them.
:good: :good: Good Luck, :good: :good:

Your device is corrupt and cannot be trusted and may not work - ZB601KL

Hello, anyone can help me with this error? "your device is corrupt and cannot be trusted and may not work properly." This is after I updated my phone from Oreo to Pie.
I tried to follow the steps from an XDA forum (https://forum.xda-developers.com/asu...upted-t3937991), When I checked the Verity Mode settings using the command fastboot oem device-info I see that it is set to FALSE.
But when I tried to run the command : adb reboot "dm-verity enforcing" or fastboot reboot "dm-verity enforcing" I am getting an error message saying : fastboot: usage: unknown reboot target dm-verity enforcing
I attached a screenshot of the error message.. I am not sure what are the next steps for me.. I need some help please...

Instead of opening another thread you should've posted this in the thread you followed. It'll be much more helpful. Also try using USB 2.0 port instead of 3.0 and with the latest drivers.
@[email protected] THREAD CLOSED! @ all interested in the subject, please follow this already existing thread, where the OP posted before this thread was created and where the OP got his problem solved.

HTC U Ultra stuck in bootloop...Can you experts verify the STEPS to solve the issue?

So, my HTC U Ultra got stuck in bootloop just 3 days after warranty ended(tough luck level : 100).
My phone runs on everything stock and no root.
I press all the buttons when powered off and it goes into bootloader mode. It displays options to boot into recovery mode, boot into download mode and power down, all of which(except power down) gets device into bootloop again.
THE PRIORITY OF GOALS IS : DATA RECOVERY > PHONE BOOTING AND WORKING PROPERLY AGAIN
I did a little research and figured out some sort of procedure by putting bits and pieces together :
1. Download ADB/Fastboot toolkit || universal driver from koush github // I have HTC Sync manager installed as well || twrp custom recovery image for htc u ultra || new ruu from htc support for rom update.
2. Now I put my phone into fastboot mode (since it doesn't show up on adb devices), connect to pc using usb.
3. I type in cmd : "fastboot devices" --> My device shows up there --> Again in cmd : "fastboot boot recovery mytwrp.img" --> the twrp boots into my phone
I was able to put this many steps together and after the last step, i have an abstract idea of what to do :
Enable USB Debugging using twrp recovery --> Use ADB Pull Command to get my all my data from phone to pc --> Use adb wipe the old Firmware (Not sure which command) --> Use adb again to flash new RUU (again not sure how, I've got an .exe file as RUU || should I get it in zip or img or any other format ? || Please help on this too) --> Finally Boot and hopefully everything turns out smooth and secure.
CAN YOU EXPERTS HELP ME TO PUT TOGETHER REMAINING STEPS (AND MODIFY ERRORS, IF ANY, OF EXISTING STEPS ) OF THIS PROCEDURE...???
