it is locked bootloader, dont flash file via it
when i try flash via mi flash:
+fastboot mode: echo missmatching
+ edl mode: laptop can detect device, but mi flash is not show
every can help me repair phone or simply is change bootloader? thank you so much

help me

Try to another miflash for example 2016.08.30 or 2016.04.01
You must flash it in edl mode if bootloader is locked .
And if you had unlocked bootloader officially you can try to unlock it again by miunlock . If success then you can flash in fastboot

Now i need re unlock bootloader?

Your boot loader has locked are you able to boot to miui if yes then unlock officially (create new miui account send request to unlock) otherwise unlock unofficial
If you have backup of efs then do not fear to
Use this guide
It worked for me.

which miflash do you have ? What devices manager shows when you connect your phone ? There should be - Qualcomm hs-usb qdloader 9008 .
If not reinstall drivers . Follow this guide

need help unbricking my phone

hey there!
i need some help here please!
i was trying to unlock my bootloader (using this guide) and it went all fine till step 17 (command "fastboot oem unlock-go"), it said i got no permission for unlocking. and now i'm stuck here. the only thing that works is fastboot mode. from there i can switch to adb using the reboot-to-edl-patch, but then i'm stuck again. device-manager shows device as usual (ports COM & LPT) and the red light is blinking, but command "adb devices" replies an empty list. tried "adb kill-server", replugging phone, rebooting computer, still the same.
so what can i do now?
thanks for helping!
Hi. You can install a fastboot rom in edl-mode with mi flash. I recomend a developer rom for this action. Then you can try the unofficial unlock from the start, but i recomend the official unlock.

sorry, forgot to say that miflash does not show the device after i selected the rom. i need to do something before i can flash via edl-mode. but what?
Make sure that you have the correct drivers installed on a 64bit machine, with driver signature off. And you cant get adb device list from there, so thats normal. Try to install the 7.1.8 fastboot rom that should work.
Well even m in a same situation.... as u said ur mobile is giving u red led blinks.. ..
And in device Manger ur fone is showed as Qualcomm 900E instead of 9008 and that's the reason adb couldn't list ur device
All u need to do is do a Google search - xiaomi deep flash cable

phone is showed as showed as Qualcomm 9008, and meanwhile i'm able to flash fastboot-rom again. still can't unlock though
AnF replies: FAILED: <remote: oem unlock is not allowed>
finished. total time: 0.016s
drivers are installed correctly, i'm working in signature-off-mode.
tried 7.1.8 rom, can't unlock that either..
maybe a stupid question, but anyway: phone had miui version 8 before i started trying to unlock.. is something wrong with that?
thanks for helping!

There is no problem with miui 8. You just have to follow the steps from this post: [Tips and Tutorials] Redmi Note 3 [ SnapDragon ] - Unlock the BEAST in Seconds!!! . Just google it, because i cant post links here... Make a efs partition backup before you proceed! With a bad flash you can lose your IMEI like lots on the forum did... I would say to unlock your phone with the official unlock. Good luck!

tried that, but no success in unlocking. same reply as mentoined above (FAILED: <remote: oem unlock is not allowed>)
is there any other rom i could try to flash? not to unlock the bootloader afterwards, but to just unbrick my phone?
I would recomend to install a global developer rom for now. And unlock your bootloader with the official method.
---------- Post added at 07:13 PM ---------- Previous post was at 07:09 PM ----------
Just install a developer ROM like you did before. Then you can decide what to do next. I would recommend to unlock your bootloader officially if you want custom ROMs on your phone.
good news: i finally managed to unbrick it!
flashing the fastboot 7.1.8 rom, and then flashing the original emmc_appsboot.mbn file via fastboot:
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn
fastboot reboot
during reboot holding volume-up + power and starting mi pc suite
..and suddenly it's unbricked!
so happy right now!
Glad to hear that.

The solution is here:
download the required files from the given link: [50mb]
https://mega.nz/#!1NhDTQoR!cP7vrchwswOfj3oHQ5saZ2d0JkcmunEn5pqyOcpZDoE
INSTRUCTIONS: [redmi note 3]
1. Get into fastboot mode. Charge the phone first. Hold the power button and the volume down button simultaenously.
2. If you can open your current rom, open developer options by clicking on the build no several times in the about phone menu in settings. and select allow oem unlocking and usb debugging.
3. if not leave it... go on and connect your phone to the PC while in fastboot mode.
BUT, before that: open Command prompt on your PC. (search it on the search box). right click on it and open it in administrator mode.
type in: bcdedit /set testsigning on
hit enter and restart your pc
(this is imp.)
4. open the zip file and extract the contents. open the boot edl mode folder and click the edl.bat file. allow it to run.
5. now screen will turn black, do not disturb it. Now flash the twrp by running flash twrp.bat from the 'flash TWRP' folder.
6. Now go to Unlock folder and run the unlock bootloader.bat file.
your phone will boot into the TWRP recovery mode automatically.
if it opens in chineese you select every tab and find the globe icon.
if the globe icon is found on any of the tab select it and change the language to ENGLISH.
wipe your system from the wipe tab:
Now download the latest CM13 SNAPSHOT BUILD ROM FOR YOUR REDMI:
https://download.cyanogenmod.org/get/kenzo-snapshot.zip
and GAPPS:
http://opengapps.org/?api=6.0&variant=mini
do select the arm 64 version and mini one.
download from your pc and copy it to micro sd card. enter this card into you phone and go to mount in twrp.
mount the micro sd card storage.
select the zip file on the micro sd card from the install tab on twrp and flash it.
now go back and flash open gapps zip file.
now REBOOT to system. everything will work fine....

You won't be able to unlock bootloader even if you have unlock code because of FRP. The only option is to use the DC Phoenix which uses some kind of backdoor - belive me, been there done that.
OK but maybe I can try... obtained my Serial via DC Phoenix... now only need the Product Idea when Dialing *#*#1357946#*#*. .... anybody can tell me please? :3

Not possible, you'll again need some program to directly read the bootloader code. What happened to your old one, it's always the same ?

I tried to Unlock via DCPhoenix (Bought for 20 €)... it sayed it got unlocked but FRP is still locked..

In Fastboot..

Yes... restore via it doesn't work.. "Your device is not supported" Error when using rescue mode.
So I think the main problem is now I can't do anything on fastboot because Bootloader is relocked (Also OEM-Unlock isnt activated in [email protected]).... So I think the only thing I can restore my 400€ Phone is to backdoor unlock it.... DC-Phoenix without success. any ideas from the real pros? Would pay 50€ if your method would work to restore my phone :/
Rommco05 said:
No no, just for drivers for communicating phone and pc. I think is some way how push imgs without unlocked bootloader

Your device is hard bricked, you cannot access EDL when bootloader is locked. You have to bring your device via nearest Xiaomi service center. I think you will pay for a fee.

Did you use the latest Mi Unlocker? Did you install all available drivers for your device? Can you provide a screenshot in the Mi Unlocker and censor your Mi ID and other account details.

So does your PC have a Ryzen processor? And does it have only USB3 ports? If the answer to any of those questions is yes, that's your problem. Get a 4 port USB 2 hub and connect thru that. Use an Intel processor PC. Elle find an AMD PC that doesn't have a Ryzen processor.

Points to ponder to unlock bootloader of Poco F1
1) After taking permission from developer option>Mi unlcok status; wait for minimum 3 days.
2) Desable driver signature in windows 10 before installing any driver.
3) Check in the device manger that the android bootloader driver must be from Xiaomi inc.
4) Turn off any antivirus including Window defender if any in your PC
5) While in fastboot mode update the driver manually to save .inf file. This is must. If you fail to save .inf file for drivers then the drivers are not installed properly even if your phone shows in device manager. Remember that.
6) Now your are good to go.
Keeping MIUI account "signed in" ;MI cloud showing only one device i.e. Poco F1 and find device must be ON before trying to unlock bootloader.

What happened?

Today my son came to me with a Xiaomi Mi A3, it was in fastboot mode so I thought to press volume down key and power key, but it went straight back to fastboot mode. I asked him what he had done and he told me he had tried to root his phone. I went to my laptop and installed adb and looked at it and somehow he had locked everything, bootloader and critical. Is there any way I can fix this?

Requirements :
adb drivers installed
Mi Flash Tool
Your device's fastboot rom
Procedure :
Put your phone in fastboot mode
Connect your phone with pc
Make sure adb drivers are installed
Open Mi flash tool application in your pc
Select the fastboot rom folder of your device
Choose "clean all" option from the bottom - DO NOT CHOOSE "CLEAN ALL AND LOCK"
And click flash
Here's a video for visual reference (sorry it's in hindi) - https://youtu.be/rJePUW8Xczw
Hope you make it, Best of luck !
And by the way, after that I think you should install a custom rom like Pixel Experience or EvolutionX because default stock android kinda sucks.

I've been using Pixel Experience, but there have been a lot of random rebooting that have made me flash A10 stock again.
If you happen to use EvolutionX, are you having reboot issues or anything like that?
Thank you, preliminary!

You need to use EDL mode, for which you need an authorized Mi Account - either use one of the paid online services or visit a service center.
