How to Unlock Bootloader? Phone with Unofficial ROM - Xiaomi Redmi Note 4 Questions & Answers

Hello guys, i really need some help here. I bought RN4 with unofficial Global rom, i already have asked for bootloader unlock permission and waiting, but i read that i cannot do it if i have unofficial rom so i tryied to install the developer official china rom but i failed. I tried with the chinese MiSuite in recovery mode, the programm goes to start the install of the downloaded rom (China Developer official from xiaomi site) but it appears an error before even start (in chineese, i cannot tell what it says) and it is like Retry or Cancel (of course Retry does nothing) can anyone help me? Thank you very much.

This one is for Mediatek I guess what about SD any ideas?

If the phone has an unofficial ROM, then it means that the bootloader is already unlocked. You can pass to an official ROM just by following this guide.
If the bootloader is locked, you can unlock following this guide (that is valid for all Xiaomi phone with locked bootloader).

Bootloader Unlock [SD Version] [Official or Unofficial] [MIUI8]

Hi!
I installed MIUI8 Dev Rom and would like to stay cause I tried several AOSP and CM Roms but I simply prefer using MIUI now.
Now I found this DEV Rom and it fits my needs as it is now.
And for sure Im facing some probs now bye unlocking BL again and rooting the phone again:
1. When I try officially to unlock, and this happens since I got my phone, I visit the Unlock page of MI. I put my Account information to login and normally I should end up on a page to beg for unlock comfirmation. Instead Im always getting an error page with chinese stuff... so official Unlock is not possible. And I tried this a felt 1000 times now.
2. Last Time I did unofficial unlock. Now. Im installing MIUI8 by fastboot and MIFlash tool. So i cant flash MIUI7 to unlock and flash back without locking again. So - how could I unlock after installing MIUI8 ???
Plz - some helf would be great, and plz forgive my poor english, im german
Thx,
Andreas

Hi herecomesmaggi, I already received an SMS with the permission to unlock the device.
I had read in Xiaomi forum that this is fixed by installing the chinesse dev rom, but that rom is only for MTK devices, is there a chinesse dev rom for kate/special edition?
Regards

First of all lemme clear this, chinese dev rom and global dev rom are same with only diffrence of languages(chinese rom has only english and chinese) and google apps.
I faced the same problem while unlocking my bootloader. it unlocked after 8 days of getting message. You wanna try other methods so be it, but i know for sure it takes a week after message is sent.
My advice - just wait it out . if any partition or so gets messed up, you will end up having problems in custom roms like others.. fp , camera, imei problems...

Wait atleast 2 weeks then try to unlock bootloader officially, same problem was with me when I was trying to unlock my "kenzo" device, but when after 2 weeks I tried it to unlock by official method it's successfully unlocked.
When I unlocked it my phone was on MIUI Global Stable 8.1.10.
If you can't wait and want to unlock it urgently then follow the unofficial method, link provided below.

Dont do unofficial Method.. I had same exact message..wait out a week
There is an easy way to know if your device can be unlocked or not
If your device details are shown correctly, INCLUDES MIUI version, under your Avatar on MIUI forum it means the device is detected properly and the bootloader will be successfully unlocked
If there is no details of your device under your Avatar, the unlocking proccess will fail
Have a look here it might assist you.....

I'll wait a couple of days, then try again (tried today and failed again). If not, im going to unlock it via unofficial method.
Regards, keep you updated XDA

Could not find the original method i used, but have just found it again, I managed to officially unlock after suffering several 50% failures using method 2 in the following link, I managed it with global stable installed as supplied with the phone.
http://en.miui.com/thread-434406-1-1.html
I used this method on my newly bought Kate device: https://forum.xda-developers.com/redmi-note-3/how-to/method-to-flash-twrp-recovery-unlock-t3473294
Works great! Rooted and installed xposed with locked bootloader. Now i can wait patiently for my official unlock code.

this one works for me;
Go to settings>developer options>mi unlock status> and press "add account and device"
after this you can try to unlock bootloader again.

If the bootloader is locked I think nothing can be done (maybe opening the device and wire it to a PC, using special software could fix it).

There's a very easy way to bypass Android lock screen but you need twrp for that, means unlocked bootloader.

How you got play store in chinese rom? Just usual install of the framework apk?
And how to root?
unlock bootloader and enable usb debugging and use the application in the below link for TWRP and then install Magisk for root.

Gcam working for Nubia Z20 below link. (May be working for other Nubia mobiles too)
Transfer the attached config file to /GCam/Configs/
then import through gcam app for proper functioning
Everything works including Night sight.

I agree on the sub forum,I just ordered one and am surprised their is not a sub-forum for the Z20
It would be interesting to see how developing goes for this device before i order it so please open a sub .
AOD
Always on display does not seem to be working "screensaver" is not showing up when phone is laid down.
Next to that in game space the animation on the back end of the phone starts but stops in like 2 seconds.
Any suggestions?
Global rom
Anyone got a Global Phone can help me make the package Global Rom? I'm really tired when using CN Rom.
P/s: Mod please make own-sub for Z20.
Can anyone confirm if the bootloader is unlockable on the global variants aka EU or US?

Yes, this method does work to temporarily unlock the bootloader on the US version. It will relock on reboot, I'm assuming due the factory recovery.
Still no sub-forum?
