Flashing original firmware - Xiaomi Mi A1 Questions & Answers

Hi, Can somebody tell me if its necessary to unlock the bootloader before flashing the official firmware. My device is not rooted and has a locked bootloader but as I wanted to flash the original firmware to refresh it, I was wondering if I can do it without unlocking the bootloader.
Thanks in advance.

Check this thread for EDL Mode https://forum.xda-developers.com/an.../guide-how-to-reboot-to-edl-fastboot-t3394292. Reboot to EDL Mode and flash using MI Flash Tool. This flashing not reuqires bootloader unlock.

Sorry but that is not correct, the A1 uses just fastboot, we don't use EDL.
Anyway just follow this guide

You just need to install miFlash or use fastboot commands if your more advanced, reboot to bootloader

[8/6/16] Unbrick RN3 from HS USB 900E with modified fastboot file

Found a way to reboot to edl mode from fastboot
All credits to @emuzychenko
1) Download modified fastboot file
2) Reboot your phone to fastboot
3) Double click on edl.cmd
4) You are on 9008/edl mode
5) Flash any fastboot image from Mi flash
You successfully unbricked your device
Hi
Try with that method also. It seams to work .
Next time I brick it again (trust me, it will happen) I will give those a try.
This is the solution www(dot)htcmania.com(/)showthread(dot)php?t=1163463
Cheked by me, the brick was to try to unlock the bootloader without the Xiaomi message.
Sorry for my english, bu ti hope to be helpful.
To restore the default Bootloader copy paste the emmc_appsboot.mbn from Fastboot Rom to the Adb foldee
and type command on cmd
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn
fastboot reboot
For those who have failed and stuck on "HS USB 900E" and the bootloader stick locked here is the solution :
1. Enter fastboot by holding vol down + power
2. Plug your RN3Pro to PC
2. Flash original bootloader from official fastboot firmware
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn
3. Type again :
fastboot reboot
and quickly hold volume up untuk it enter "sideload" mode
4. Install Mi PC Suite from this link en.miui.com/thread-225600-1-1.html
5. Let the Mi PC Suite download the latest chinese firmware, just sit and wait until it done
6. Lets Brick the beast again

Have you tested this method yourself? I think this is for people who bricked the device but had stock recovery inside, what about people who has twrp and bricked the device? Also I dont think you can flash anything through fastboot in locked bootloader
IT WORKS

Yes i did .. and its not allowing me to flash anything .. Getting Error Device is locked :/
failed bro, getting error device is locked using QFIL.:crying:
Guys, please mention the reason behind your device getting bricked too when you are reporting what worked and what didn't. Like whether during unlock bootloader process(without xiaomi's permission) or flashing custom ROM(most probably MIUI official updates) via twrp.

Go to service center. They will repair it

i've tried this myself. In HS USB 900E you can flash aboot through fastboot whether you stock recovery or twrp before bricked.
Rajdip said:
I have found few ways by which people may unbrick from HS USB 900E state without test point, but those guides are for other devices, needs thorough testing for Redmi note 3.
Tools needed:-
1) QPST http://www.androidbrick.com/downloa...qcn-for-lollipop-android-5-0-6-0-marshmallow/
2)Nubia tool studio https://drive.google.com/folderview?id=0BwtoIMKf470SRUxfdHA5cU14ZTQ#
Now follow these guides for reference,
1)http://www.androidbrick.com/ultimat...ide-snapdragons-are-unbrickable-qhsusb_dload/
2)http://www.androidbrick.com/unbrick...-you-have-the-right-kind-of-rom-qhsusb_dload/
Only people with hardbrick(900E) and locked bootloader can this test methods, Please try and leave your feedback, maybe we will find a way to unbrick without opening the phone and voiding warranty. Good Luck

[HELP] How Do I Unlock Bootloader without a Firmware

Hello.
Long story short:
I have a OnePlus2, I can boot in Fastboot mode and my PC does recignize the fastboot device.
fastboot oem device-info says that Bootloader is locked and when I try to unlock (fastboot oem unlock) it states "okay" but cannot boot into system because there is none installed. -> Bootloop
I cannot boot into recovery nor install a recovery due to the locked bootloader.
My Question:
Is there a way to unlock the bootloader in fastboot and/or install a boot.img?
I am happy for any help that I get.
Have a good day/night
SoulSnatcher
No, but why you don't have system?
You have stock recovery download official signed full zip and flash it. Recovery.
Also unbrick guide using the one you need Qualcomm drivers

A2017G How to relock bootloader on Nougat B10

I came back from LOS 16.0. Flashed A2017G_B10_NOUGAT_FULL_EDL in EDL but there's a warning that my bootloader is locked. I wanted to relock it but the warning prevents me from entering bootloader or fastboot (or maybe they are not even present....). Next I flashed A2017U_FASTBOOT_UNLOCK_EDL in MiFlash but it did not do anything. It flashed OK but I still cannot access fastboot. Should I flash some marshmallow rom? Thanks in advance.
I have the same problem. Cannot enter fastboot mode on Nougat ROM.
Ok I found the way usin Axon 7 Toolkit
1. Set the Android version to 7 using option 13
2. Perform unlock bootloader
Following instruction Axon & Tookit gives you EDL image of the proper fastboot partition giving the possibility to enter fastboot mode
then fasboot oem lock
I wanted to say thanks that works, but apparently my phone is bricked now - it hangs on green ZTE logo. PC recognizes it as DFU. Cannot enter EDL either. I guess I look for some guide how to recover from this situation
Managed to fix that. Somehow I was able to enter fastboot. It said my bootloader was locked so i flashed TWRP and from TWRP using ADB installed stock Nougat rom

Trying to re-lock the bootloader

I have a A2017U that I just downgraded to B35 using this guide: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413
I want to lock the bootloader to stop the annoying boot warning but can't get into fastboot when using AXON7TOOLKIT.
I tried flashing A2017U_FASTBOOT_UNLOCK_EDL (downloaded from https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128) through miFlash but I still can't get into the bootloader.
What can I do?
EDIT: Thanks everyone! I used the toolkit to unlock the bootloader again, then locked it. For some reason I couldn't access the bootloader even though i got the bootloader ulocked warning.

You only want to lock it because of the boot warning? There are flashables to get rid of that... I dom't know which exact files there are for stock B35 or Oreo but there are some going around.
hell you could even go custom and use the splash bootstack if you wanted.
If you want to lock anyways, you have to get an A2017U B19 package and flash it via EDL Tool (or MiFlash). Right after that you'll have fastboot. enable oem unlocking then enter fastboot and issue fastboot oem lock and you're done. But it's way too overkill if you want to just get rid of the 5 sec screen

you need to flash original stock rom for your device trough edl. (rom your device came from factory,marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!
You need a locked bootloader to get rid of the warning message ( dont flash any mod package that claims it delete the warning page)

The phone does not enter fastboot / bootloader mode

Hi everyone,
I am the owner of an A2017G, unlocked bootloader.
I tried them all, but all of them and I can't get into fastboot / bootloader mode.
Ihave flash rom via MIFLASH and AXON7 EDL TOOL using rom Nougat and Oreo, but the result is always the same !!!
Do you have any ideas to help me, perpetuate?
Thank you.
Use miflash and flash unlock bootloader image by Turkdev, even in oreo it will give you fastboot menu.
I did this 3 days ago to relock my bootloader
Use this tutorial:
https://forum.xda-developers.com/axon-7/how-to/guide-unlock-bootloader-easily-t3704595
The reason you lose your fastboot menu because you unlock BL with another image (using Axon 7 EDL tool perhaps), but if you do unlock with turkdev image in tutorial, your fastboot menu will stay there
