Bootloader unlock failed

Hi guys...so i updated my phone to 2.3.4 then rooted it with the zergrush method.Now i'm trying to unlock my bootloader so that i can flash cyanogen mod.I followed all instructions from the cyanogen site but i'm getting this error...
(bootloader) Unlock phone requested
FAILED (remote: oem unlock failed!)
finished. total time: 0.000s
Does anyone know what this error means.

Are you 100% sure you can unlock yours? If you're sim locked then no you can't.

I'm not sim locked and i followed the instructions to the t from start to finish.I even got the unlock key twice to check if that was wrong but both keys were the same.

I did the unlock bootloader check and it confirmed i can unlock it.
All drivers installed and can connect in fastboot mode ie blue light.
Getvar command was good ie 0.3
But i still get that error.

You typing in the unlock key correctly? Not getting the O/0s confused?

Yeah there's no 0's or O's.No but if it wasn't factory unlocked would that cause this problem.

In cases like that I think you may have to pay some dude to get it unlocked. Try giving these forums a search. There's a link to the guy who does them someplace on here.

I might have to look into that...thanks for the help.Nice name by the way .

One more ? if i flash cwm without unlocking my bootloader would i still be able to flash custom roms.

As long as the custom rom runs on the stock kernel I think so. I've yet to try the Darkforest one. I couldn't get it to work when I was on stock kernel with a locked bootloader. So I wouldn't hold your breath on that one. I can message the results if I manage to get it to flash via CWM. Thanks for the compliment Just putting back in what I take out.

I think that thread for the pay service bootloader unlock was removed for some reason but he has a website now

Is your phone connected to your PC with the latest drivers in fastboot mode.
Make Sure YOU have MADE a TA Backup.

If your phone doesn't allow boot loader unlock, Your phone is probably network locked. Try unlocking phone from carrier. If it still doesn't allow, try reflashing firmware with Sony pcc

Mi Max not able to root

Hello sir
I have been trying to unlock bootloader of my mi max(qualcomm indian version) for some time. I already got the permission to unlock bootloader.
But i am not able to unlock it because of drivers problem. my device is not getting detected in MI UNLOCK TOOL although it is being detected in MI FLASH TOOL. What should i do please help me .. i am using the latest tools and latest drivers in my pc. Also i tried installing new windows 10 in both my pc and laptop but the same problem persists.
Thanks in advance..

Were you able to unlock bootloader ??
If yes then flash recovery twrp
Then

Sir, the process given to unlock bootloader on Mi.com or else supporting websites are not working at all.
How can we proceed further if this not happening ?

Wait for 3-4 day after receiving code from xiaomi.
As there servers are updated after 3-4 days. Sometimes may take more than a week..
Unlocking is different and rooting is different. Do not attempt to root without unlocking bootloader.

Is my Mi Mix 2 bricked? Bootloader accessible

Firts of all I give you a summary of what happened:
- Bought the Mi Mix 2 at Gearbest
- Either it came with the Global Beta Rom installed or I did it (don't know it anymore )
- Used the phone for several month with Global Beta
- Had some Bugs an wanted to change to Global Stable, that was when the problems began
- Downloaded the Global Stable ROM from Miui Site and installed it via the Update-App in Miui
- After installing (no Errors displayed) the phone booted up and had to activate the device
- After that I had to select Language and Region; As Region only China was selectable and after selecting it I got the boot loop
So I knew I installed ROMs via fastboot on my previous devices and tried that. But it is written that the Bootloader has to be unlocked.
I can't unlock the bootloader, because USB Debugging wasn't enabled and I did not connect the Phone to the Mi Developer Account .
So I am stuck now:
- Boot-Up => Bootlopp
- Fastboot flashing => locked Bootloader
- Unlocking Bootloader => Dev-Account not linked
Is there anythin i can do to recover the phone?
And I was wondering what have I done wrong that I got into the bootloop? As global bet was installed I thought I would be safe to go to Global Stable...

Is there anyone that can help me with this problem?
Do you need more information?
It would be great to know if there is a way to recover the phone or if it is bricked.

Thanks for your answer!
The problem is I can't unlock the bootloader, because I didn't bind the phone in the dev settings to my Mi-Account and after flashing and resetting the debug-mode isn't active either.

I still cant understand how u got stuck there ? sorry dude I hope somebody here will help u asap

I used to solve this problem by using MI FLASH. You can download the file,global or chinese version of the rom file,but the file must be in the fomat img Which can be downloaded from the official forum and then flash via miflash This is probably not a problem. Good luck.

If you have adb enabled, it's fixable easily with available tools. If not, you need to either disassemble the phone (and boot with contact points to force bootloader unlocked), or take it to a xiaomi store in HK or China (they can request Xiaomi CN to make a custom firmware for your device which can unlock bootloader without normal permissions - I had to do this for my Mi Mix 2 Special Edition, which can't really be disassembled without breaking the screen).

Don,t be that complicated.The mi flash tool can be used even if your device is stuck.but the flash rom file must be an img file. Forum of xiaomi He has to give and use mi flash tool latest version Compatible with windows.At least not support window xp. You try to study. It is easy to solve.But you will choose

I attached a sreenshot of the error I get in Mi Flash Tool.

The first time I didn't pass the same, but when I changed the new file,it passed. You try to change the file or use the Chainese file.

The file may not be complete.try again

I downloaded the chinese stable version to test. Now I do get another error when I want to flash.

At miflash status,it is already said that it cannot be deleted in lock status.

If you follow the steps that I have already recommended, do not go through. Would have to ask for help from xiaomi, let him unlock the wheel, which you must tell him why he will help You probably won't travel on your own because the mimix2 price is only $ 300.

Search "Unbrick Mi Mix 2 or EDL mode Mi Mix 2 at Google.
