[HELP] RN3 SD Unclock bootloader "Couldn't verify device" - Xiaomi Redmi Note 3 Questions & Answers

Hey guys,
I got my RN3 a month ago and since last 2 weeks i am trying to unlock the bootloader using the official method.
I had asked MI for permission and I got it within 3 days. Now since 2 week I am trying to unlock the bootloader but I keep getting the error on MIUnlock "Couldn't verify Device".
I am using the latest MIUnlock version.
I have searched extensively for a solution to the problem but unfortunately all the work arounds are not working for me.
I have tried it on the stock ROM that the phone came with.
The latest stable global ROM from MI V7.3.7.0. MIUI7
The beta global ROM from MI MIUI8
Same error everywhere. The process stops at 50%.
I am skeptical to try the unofficial method since it could brick my phone. But may go through with it if there is no other option.
Basically I want to root the phone and flash a CM13 ROM.
Please help me out
Thanks

Mine had said the same error failed at 50% - mine shipped with miui V7.3.6.0 (some vendor firmware I guess), here is what I did to fix it.
I have the redmi note 3 pro so this will apply only for the kenzo (snapdragon version)- I am not familiar with the mediatek one.
1. Install Xiao Mi Flash (beta) , then boot the phone into fast boot mode (from power off state - hold vol down + power until you see it say fast boot.), in Mi Flash at the bottom select clean all
2. extract the kenzo "fast boot" firmware
http://en.miui.com/a-234.html (find the firmware in the list)
IE:
Redmi Note 3 Qualcomm Latest Global Stable Version Fastboot
(kenzo_global_images_V7.3.7.0.LHOMIDD_20160523.0000.23_5.1_global)
3. Select the extracted firmware folder in the Mi Flash program, hook the phone up and you should see it in the list, then click flash to flash it.. (this will erase all data)
after it finishes let it boot up it might take 10-15 minutes, then you can try to unlock it again, at this point it should pass now verification and unlock officially. - after success let it reboot again and it might take another 10-15 minutes to finish up.
(this is because it clears the phone data so it has to re-optimize all the apps).
do at own risk it worked for me but due to all the various methods the vendors use to flash this phone who knows if it will work for everyone...

hello,
i am not able to use miflash(beta) due to some qualcomm driver error because i am on 32 bit system. Instead i am using miflash 2015 10.28.0 which have 3 options like flash all, flash all except storage ,flash all except data and storage.which one to choose?
look at the image i have attached for your reference

first I suggest installing the Mi PC Suite (just to get the correct drivers installed), then try XiaoMiFlash again
http://en.miui.com/thread-92720-1-1.html
here is the Xiao Mi Flash I used.
http://en.miui.com/thread-281979-1-1.html
MiFlashSetup-Beta.zip (29.53 MB, Downloads: 96818)

I had to link my phone first before the Unlock tool would work. So login into you Mi Account on the phone first.

I had the same problem because i hadnt installed the miui dev rom yet..

the only solution is flashing DEV ROM
it worked for me

help with xiaomi redmi 3 pro

Hi all:
I came to this forum in search for help with mi xiaomi redmi 3 pro.
I bought this phone a few weeks ago, and so far i'm really very happy with it, but unfortunately the rom installed has not my language completely, some parts are in PT/BR and aome in english.
So I would like to install the EU rom that has the full portuguese package included.I have already taken the first steps.Asked to xiaomi permission to unlock bootloader, which was already granted, but this step is my firs problem.I follwoed all the instructions connected the phone in FASTBOOT mode to the PC but whenever it reaches the 50% I get a message saying: "couldn't verify device-not connected to MI phone.try again"
Someone told that this is because I don't have the CHINA DEV installed, and this is my 2nd problem.I have downloaded the last china developer to my phone, I go to config-update-choose update package then I select the downloaded version, but then again I get the message error : can't verify update !!!
And this is it, i'm really blocked !! what to do ?? do I have to root my phone using something like KingoRoot and lose my warranty ??
PLease help me.
Modified bootloader
Try this modified bootloader and then flash xiaomi.eu ROM
sSo if I understood it right I have to do this:
Installation :
1. Unrooted device
- download file ido-TWRP-3.0.2.0-miflash.zip
- extract and flash using miflash in download mode
this will also install official TWRP 3.0.2.0 to the device
and next step I have to instal the xiaomi.eu rom. right ??
Ok after reading a lot I found that to do that I need a PC with a 64 bit windows (mine is 32 )
Besides that for any strange reason I can't onstall the drivers !!!

[Advice/Tip's] Unlocking BL/Flashing recovery/1rst custom ROM [Redmi 3S]

From my hard time unlocking Bootloader and flashing recovery until first custom ROM of 3s, I'll share some advice
- If stuck on 50% at BL unlock, >use chinese dev rom (I used this: "land_images_V7.5.1.0.MALCNDE_20160629.0000.25_6.0_cn">MiFlash has different names but it's all the same program, and if you wanna flash something, you have to run the .bat of the extracted ROM first! >And then start the MiFlash Prog. >sign into your MI account at the dev rom in your phone >activate 'find device' and all other account options there which you can tick there at login >stop account sync of the rom and start it again >go to i.miui.com and sign in >RETRY
Custom Recovery & custom ROM
- Flashing the Chinese TWRP will cause bootloop to the dev rom ! And you likely cannot boot into recovery by just a button combo, so just reboot the recovery >using recovery< once, after you had confirmed to make changes on system (at startup of recovery) >> And keep your ROM plus Gapps on your SDCARD as you cannot access the recovery easily, if not by >fastboot reflash< or working ROM (using 'reboot recovery' in it, later) ! Do not flash Gapps after you booted the ROM already, as this will cause Gapps to fail!
Enjoy~

Is it mandatory to use china dev ROM? I am on global dev. Checked the ROM zip, it contain recovery img. Its just inaccessible due to locked bootloader.

you must use this exact rom, at least this was the one i was using. and there is a guide where it says how to flash it with miflash but i lost the link. "land_images_V7.5.1.0.MALCNDE_20160629.0000.25_6.0_cn_e5777810ad" from en.miui.com
and yes, afaik you do have to flash this rom with miflash that's mandatory. chinese dev rom is must.
HOnest Solution...
Honest Solution..
If you got Permission for unlocking just wait for 6 to 10 days after getting the permission..
No matter which rom u are on..
You will unlock successfully.. Just follow the process of i.mi.com.
Well i was also facing the same issue, what really helped me here is,
1. Removed MI Account after getting unlocking permissions,
2. Re-Added MI Account by using the mobile no. (Logging in using Mobile no. is mandatory)
3. Located the phone from i.mi.com (find device option)
4. Switched off the phone and booted into fastboot mode.
5. Opened MI Unlock and logged in here from Mobile No. and unlocked.
Got success.

unlocked boot loader successfully . I got code week ago and i had same problem stopped at 50%.
Finally i decided to install Chinese developer rom but for last time i thought let me try unlocking again with global rom. Fortunately it was a success.
Suggestion:
- allow unlock bootloader option in developer setting.
-when ever u try unlocking.Try login with phone number ,email id and mi account code.(three try every day)
-do the same with three acc in i.mi.com(locate your phone.)
-remove finger print security.(remove security)
-And have some patients. It will get unlocked when xiomi update their database.
-i got two different codes with my email id and phone no. I don't know why i have only one account in mi.com.But if it shows u"u need to apply for unlock code "again then get it.
really frustating.
I was really surprised that I got the permission for unlocking the bootloader just 30 min after applying for request. But got stuck at 50%. Tried all solutions. I'm getting that "Current account is different from the account info on the device". Somebody please help. It's already two weeks since I got the permission. Also tried internet on/off method but no use.

1. Try removing other devices from your Mi Account for the moment, add them later if you want.
2. It takes a week or so to update your information on the Indian Xiaomi servers.
3. Make sure you're using the same account in which you got the permissions to unlock and the same account is logged-in in your Mi Account app.
4. Enable Developer options and tick "Allow OEM unlock"
Personally, I waited for 6 days after getting permissions. I was also getting stuck at 50% with a few error messages but after waiting, the unlock was successful.
I had tried a lot of things that included, switching internet on/off, factory resetting MIUI, trying multiple times, reinstalling drivers, maybe I flashed the fastboot ROM too, a few times. But after all of that, few guys suggested me to wait for a week or so, so that my device's information may be updated with my account, I did that and got it unlocked after a couple of days without any problem.

It's been 14 days since I got permission. I'm not able to flash a fastboot rom because my phone is not entering to EDL mode(It's just booting to android instead). However
"I'll try again"

You need to get into fastboot mode, turn off and press volume down and power to get into fastboot

[an all fix for bootloader unlocking issues] on 3s/prime/3x

Please kindly refer to the thread and read the details steps and instructions because it seems like everyone is trying to hit the unlock procedure without knowing that the stable(global) version of the ROM is not apt for the official or any unofficial unlock procedure !
PLEASE MAKE SURE YOU HAVE DISABLED DRIVER SIGNATURE VERIFICATION IN YOUR SYSTEM.
Unlocking Bootloader Procedure:
1. Download zip file (recovery file) of OFFICIAL MIUI China developer ROM for your device :
http://bigota.d.miui.com/6.12.8/miui_HM3SGlobal_6.12.8_b00ffce744_6.0.zip
Please don't get confused with the link as it's indeed a Developer ROM by 'global' in between the link and not the Global stable ROM, you can check it yourself.
Other ROM would not work. Then put it into phone storage. Go to Updater app, press the three dot on upper right corner, and select 'Choose update package'. Choose the zip file you just put in phone storage. The update will wipe all user data, please make backup beforehand.
2. Log into the Mi account which has acquired unlocking permission on your device. Make sure it's the same with the account you sent your request. It's recommended to connect to the Internet for Mi account to sync
3. Turn off your device, press the Power button and Volume - button at the same time to enter bootloader mode
4. Log into the unlocking tool on PC with the same Mi account. Connect the device with the PC using USB cable
5. Press 'Unlock'. The unlocking process will complete in about 10 seconds
For those who already bricked your devices you may using Mi PC SUITE to reflash your device.You are advised to download it to install necessary files (ADB and so on) .
Hi... as far as i know.. you need to be on the same rom from which you have applied for bootloader unlock..
i bought new redmi 3s last week.. and same day applied for unlock... and when going through different threads.. lot of people saying that we need to be in developer rom or Chinese rom to unlock boot loader..so i downloaded global developer and installed it..
with in 2 days i got confirmation from xiaomi that i have permission for unlock.. to my bad.. every time i tried to unlock boot loader its stuck at 50% with current device information is different error..
so finally decided to downgrade to the same version from which i applied for unlocking.. so tried Deep flash cable method to put phone in qualcom loader to bypass bootloader... and installed same global stable version.. after successfully installing stable version tried unlocking.. and voila... bootloader unlocked with in 10 Seconds...without any hitch...
So if you want to unlock bootloader... wait for atleast 7 days after you get confirmation message from xiaomi...

Yes, glad someone else noticed it too. Yes I had trouble for a lot of days with developer ROM after getting permission a week back but no luck.
PS: Disabling Driver Signature Verification is paramount in this process.

Xiaomi different versions LOL + "current account is not bound to this device!' error

Xiaomi different versions LOL + "current account is not bound to this device!' error
I finally found out there are looooooooooads of Redmi types, unbelievable!
Maybe Xiaomi should minimize their offer, I thought I had a Redmi Note 3, but I finally found out it's a
Xiaomi Redmi 3 IDO (3A) Snapdragon LOL
I ordered one for my daughter, and now I see it's actually a Redmi Note 3 (bit more expensive and different at the back).
==> So i'm busy checking out how to flash, I got the official sms to unlock the locked bootloader and the first part goes to 100%, but theb I have another error : "Current account is not bound to this device!"
I'll guess some more errors will follow seen this long & difficult process
I dowloaded the latest miui_MI6Global_7.8.10_024aaf1afd_7.1 of this week, but now I need to get rid of that error & locked bootloader.
Do I need to flash an old beta rom first or something to get rid if this error message ?
Nice to see a fellow Belgian here
I am a bit confused. You are trying to flash your Redmi 3 (ido)?
Because the ROM you say you've downloaded is one for Xiaomi Mi 6...
Could you provide some information (screenshot of your 'about phone' with the current installed MIUI ROM etc?)
When I unlocked my ido's bootloader last year, I flashed the Chinese developer ROM using MiFlash, coming from a fake vendor ROM via EDL mode. Then in China dev ROM I unlocked the bootloader using MiUnlock.
After that I flashed TWRP (flash lazyscript before booting into the system or change to custom ROM immediatly because dm-verity is a b****).
I believe in recent ROMs, EDL mode was blocked by Xiaomi.
About the error: make sure you log in to the unlock tool with the same account as you are logged in to on your phone (the account with unlock permission). Then go to "developer options - Mi Unlock status" and make sure your account has been bound to the device there.
USB-debugging should be enabled, as well as OEM-unlock.
I do not know when you received the unlock code, but it is possible you'll have to wait a week or so. A lot of people have found that it suddenly works after a few days of waiting.
If you cannot switch to a developer ROM due to locked EDL mode, you should be able to flash your ido with locked bootloader using xiaomitool. http://en.miui.com/thread-835254-1-1.html
With this tool you can switch between MIUI ROMs on a locked bootloader.
I don't see any reason on why you download Mi 6 (sagit) recovery ROM instead of Redmi 3 (or Redmi Note 3 if it's what you're talking about) one. For "Current account is not bound to this device" error, wait for at least a week after you bind your Mi account with your phone before unlocking.
Good luck.
Sent from my Redmi 3 using XDA Labs
Haha greetz to Belgium too Yes I was a long time since I checked the latest roms / Xiaomi phone versions
Now I have a rooted stable MIU9 V9.2.2.0 Laicnek and looking for the best battery saving Kernell, hope I can flash this simply with TWRP as everything is installed allready
What do I need to choose again in the options to flash a Kernell only ?
Otherwise the Lineos 15 with the latest Oreo (if there is an official version 15 already, as I see only a beta 2)

EDL Authorization

Hello I need help with my Note 5. Downloaded latest global rom and mi flash tool.. entered edl mode with test point and i got a proplem saying "Only nop and sig tag can be recevied before authentication.".... now i assume i need authorized mi account to flash the rom but i dont have one and i see no way of getting one. I am currently on fake rom on a global version of the phone (the one with dual camera xiaomi note 5)
What i want right now is to flash any rom that can request for bootloader unlocking since in this fake rom that is disabled and my loader is locked..
any help?
This forum is for Redmi 5 Plus / Note 5 (India).
Please go there and ask for help for your problem:
https://forum.xda-developers.com/redmi-note-5-pro
Best regards,
skrubxgt
Use EDL mode if your device bricked and it works only with designated rom, china to china and global to global because in this case your bootloader is locked. And before proceeding flashing thru EDL, you have to prepare eveything properly, such as disabling driver signature enforcement and installing correct driver (QD Loader 900D)
So, have you prepared and done all those things properly? 2 days ago I just flashed my device thru EDL due to failure flashing and now my baby is waking up
