Ok I was also stuck at 50% like everyone else, what I did was, I flashed the "Latest China Developer" ROM

YOU WILL NEED
1-China developer ROM (choose Redmi 4 Prime Latest China Developer Version Fastboot File Download)http://en.miui.com/a-234.html
2-MiFlash http://xiaomitips.com/download-in-progress/?dlm-dp-dl=1474

Just follow the steps on the website, I'm gonna put them here anyway:
1)Install MiFlash on your PC
2)Fastboot your phone Turn off the device. Then Press the Volume DOWN key and the Power button at the same time (bunny with a hat) and after that, connect the device to the PC via a micro USB cable
3)Open the file you downloaded (it should be a .tgz) with winrar/winzip/7zip
4)Extract the file inside it (it should be a .tar) to any folder
5)Extract the folder inside the .tar it should be something like "markw_images_7.3.30_20170330.0000.00_6.0_cn"
6)It should look like this http://i.imgur.com/N6PYADk.png
7)Now run MiFlash has an admin and paste the directory of the markw_images_7.3.30_20170330.0000.00_6.0_cn folder like so: http://en.miui.com/static/article/innerimg/tongyong/tongyong-3-3.jpg
8)Hit refresh, select flash_all.bat at the bottom and click flash http://en.miui.com/static/article/innerimg/tongyong/tongyong3-4.jpg
9)Once flash is finished a chinese button shall appear, click it and reboot your device (It's first boot so it should take alot of time, mine took 10min)
10)Just try to unlock bootloader now :)

TL;DR: Flash china dev rom http://en.miui.com/a-234.html

I got the message that Binding time is too short. How to solve?

I got that message also with the latest version of the unlock tool, downloaded straight from Xiaomi's website (v. 2.2 or something). Then I tried v. 1.0 downloaded from here and it went through. 1.0 version was chinese letters only, but only couple of buttons to click in the same places as the english one (v. 2.2), so it doesn't really matter.

Yesterday I got 52 hours and today 32 hours. I think that I'll wait just one more day to see if I can unlock. But can you send me the link to download this version of mi unlock?

Greetings all,

Finally unlocked my bootloader since December when i got the phone, i didn't have much access to a windows pc... anyway, needed to ask again for unlock permissions, in half an hour got them, downloaded the mi unlock from the miui site and connected the phone to the computer and voilá, it just worked "first" time.

Thanks for the info all these months ;)

I've tried everything to unlock the bootloader of my new Redmi 4. I received unlocking permission today, but I always get stuck at 50%. It reports that the details are different, but they're not. I logged into the unlocking tool and the phone using the phone number, enabled Find My Device and successfully located it, enabled OEM unlocking, enabled ADB when the phone was booted, etc. It's so frustrating. I'm running the latest dev ROM.

Edit: Do you need to have a sim card in the phone?

Edit 2: On my third computer and third Mi account, it worked. Don't ask me how.
i did the same as you mentioned to unlock my redmi 4. tried the latest official unlock tool and the one mentioned here, still the unlocker says " current account is not bound to this device" error.
does anyone has a fix for this?

    Okay so me and probably others have/had problems with unlocking your Xiaomi Redmi 4 Prime.
    These are simple steps to succes.

    what is needed: Redmi 4 pro, ADB drivers

    1. Sign to Xiaomi and apply for unlocking http://en.miui.com/unlock/
    It is important to add correct data.

    2. Connect to your Mi account on the device and enable Find Device option under Xaiomi cloud
    if it is done correctly u will be able to find ur device at https://i.mi.com/

    3 Wait for permission u will receive SMS message.

    4. When permission is aquired and device is connected to Mi Cloud we have to try to unlock the device.

    5 . Download Mi Unlock software ( added to post up there )

    6 .Enable developer settings
    System info -> couple of clicks on MiUi version
    Back - > more settings -> developer settings - > Enable OEM unlock

    7. Reboot to fastboot ( Vol down + power ) till some (russian?) bunny appears

    8. Perform unlock from Mi Unlocker and press
    Left button
    enter Login(email) and password to mi account
    Connect the phone and press the button !

    9 Reboot. You should be done Congrats !

    You can install miui global now or any other rom. to Perform you have to :
    1. Boot to fastboot
    2.Download Brigudav Recovery https://forum.xda-developers.com/redmi-4-prime/development/recovery-twrp-3-1-1-2-brigudav-t3656372
    3.connect the phone
    4. in console window type: fastboot flash recovery RECOVERYNAME.img
    5.Boot to recovery and install the rom

    Happy flashing !

    Hi
    I have recently purchased a Redmi 4 Prime phone that came with the vendor rom and I wanted to flash the latest china dev rom, but am stuck in bootloop. cant enter DL mode, but fastboot is OK. unfortunately none of the adb commads work, the phone is recognized under "fastboot devices" but not under "adb devices". I have tried the fastboot2edl v2 method but is goes straight into bootloop. can you please suggest what to do and help me out?

    Try to turn it off and press volume down + up and power until the LED flashes red and connect USB - it should be recognized as Qualcomm ******

    If not, then build your own deep flash cable or order one on ebay or something... - with that u can reach the DL mode on nearly every Qualcomm device

    Then why you say in the unnofficial way this "Warning do not flash xiaomi.eu global or any other unofficial rom this way !".
    It's something new what you say?

    Yes, 4pda patched bootloader appeared after fastboot oem unlock-go solution.
