Redmi 4x unlock - Xiaomi Redmi 4X Questions & Answers

Hello,
As second phone I've got a Redmi 4X from my father. Phone cames with the China ROM, I would like to upload the Global ROM. In order to do this I've got to unlock the phone.
On Dev options, Mi Unlock Status function, I always stuck on the message "Don't disconnect from the network, sign out of your Mi Account, perform a factory rest, or erase system data. If you've already done any of the above, add your Mi Account again; otherwise, you won't be able to unlock your device."
I've try what the message says, no luck.
I suspect it's something blocked on the Xiaomi servers about this phone. Anyone can fix it?
Thank you!

I've solved putting the phone in EDL mode using the test points on the board.

is there anyway to unlock bootloader without permission on miui 10?

One of my friend has redmi note 3 kenzo
It would be very helpful if someone has a trick to unlock bootloader without permission.
I think there is no need of permission for old devices for unlocking bootloader.
One of my friend has Redmi note 4X and was able to unlocked without asking for permission.
even this worked for his Redmi 3S but with 72hours of waiting time.
Just logged in into Mi unlock tool with same account as in device and your friend should be able to unlock bootloader (maybe not right away but with several hours of waiting time)
Problem isn't that
Problem is :- He is not able to add his mi account from developer option for oem unlocking.
An error occur always.

Yes, right. Log in in Mi unlock tools on PC with the same account as in the phone and then connect phone in fastboot mode but first make sure oem unlock is enable and usb debugging is turned on. ignore the account log in in phone.
just give it try.

Log out of mi account in your phone, log in again, associate that account with your device then try unlocking the bootloader. Worked for me that way.

Don't be confused. Older devices are unlockable without even applying(i am saying this on my experience) i have unlocked two of my friends Redmi 3S and Redmi note 4X without even applying to xiaomi.
never devices needs to have permission to unlock and it takes time and request can get rejected if the it does not meet their conditions.
if you have old device such as more than a year or more.
Just download and install Mi flash tools and you are good to unlock but it still shows error of 50% or stuck at 99% so you'll have to unlock after remaining hours which will show on mi unlock tools.
I just used this method to unlock my Mi Max 2, Miui 10

Its most likely server error from xiaomi as it happens many times and almost everyone faced it whoever tried to unlock i guess.
Please try again later and if possible try and connect to different WiFi network before adding account.
Also you can just give it a try by enabling USB debugging, oem unlock turned on from developers options and then just turn off your device and boot into fastboot mode and try unlocking it, regardless of adding mi account.
You should also try some different versions of mi unlock tools(preferably older version).
As i have mentioned it worked without even adding account and it took 3 days to unlock as it was getting stuck at 50% or 99% and was asking to wait for 72 hours and later it unlocked in first try so this should work for you too.
There is unofficial way to unlock bootloader please search on XDA/YouTube or some other websites.

See. This is why you should flash WITHOUT locking BL in MiFlash, if something goes wrong u can do it again but if you have locked BL, then you probably need to use EDL

I wasn't able to solve any problem with the EDL point yet. Sorry to say that. Therefore, as Marcelsky said, don't lock your phone by flashing. Pay attention to the button in the Mi Flash. Otherwise may the phone stuck in the bootloop, or will not start and ..

K20 Pro bricked

Hi guys,
I have just read a previous post from "abdulmaalik1tt" about a problem after an accidental bootloader closing. I have a similar problem but in my case, I think it is harder.
I intentionally closed the bootloader after installing everything in my K20 Pro, but I didn't know that if it is closed by other one than the one who opened it, the phone will brick.
I tried to unlock again, but in 99% the app gives me an error, and ask me to change something in developer options. Obviously, I can't do so, because the phone doesn't boot.
I tried to use miflash but it gives me an error because the bootloader is now closed
Is there a way to unbrick my phone? Should I throw it away through the window?
Thank you in advance.
same case, you open the back, do test point method, if you Mi account is not EDL authorized, you can borrow, or call the guys that help many k20 pro user in XDA.
please help
do you get any solution to this case? i have the same issue.
I had the same problem. Sadly the only thing you can do yourself (it's also the fastest and cheapest option) is to open your smartphone, short the two EDL points on the motherboard to access the EDL mode, contact someone with an authorized Xiaomi account to input his username and password in the Mi Unlock tool (through Teamviewer) and enable you to install the stock Chinese firmware.
The only other option, sadly, which I didn't like at all, is to send it to a Xiaomi service point.
And all of this because the default option in the Mi Flash tool is "install and LOCK". Idiotic.
PM me if you need the contact of the guy with the authorized acc.
if you can boot in fastboot try unlock bootloader with miflash unlock but old version it work for me later unlock bootloader you can flash stock with miflash again
I am in same boat - fake global rom, flashed forgetting to set to Clean all only - so bootloader locked.
Seller is no reachable - so looks like this is my only way.
When you guys say 'short' these two pins - how did you do that? with a paperclip? and you mean from one pin to the other pin?
--Update for future reference of others---
My K20 Pro has been restored with help from the Russian contact provided on previous page - ask nicely, he is very busy so don't waste his time.
My experience was great, he was patient, we made appointment time over whatsapp, we have to try twice as i couldn't get into EDL mode (try a different pair of scissors or tweezers).
Once in EDL he logged into his mi account via my team viewer session and flashed the rom i has prepared (chinese original fastboot).
Right after flashing - had a bit of trouble booting up the first time, it didn't boot when pressing the power button (no usb cable), when i plug in USB cable - it showed 100% battery but also didn't boot. Had to play with disconnect then reconnect the battery THEN unplug cable. And it finally booted the first time.
Thank you guys!

I ended up blocking the bootloader accidentally giving my k20 pro when changing the rom, but when passing the rom by edl, the device does not turn on in any way, when passing the Chinese rom I have to block the bootloader?
Worth Checking out he thread, maybe older mi unlock can remove the bootloader flag for you ? cheers

Bricked Redmi K20 Pro, stuck in Recovery Bootloop

After trying all kinds of roms from here, I decided to go back to basics and flash a global stable ROM.
In the Mi Flash software I forgot to check the "Clean All" button, and left the default(I don't know why this is the default) "Clean All and lock"
Now, I'm stuck in a recovery(can go to fastboot as well) bootloop, can't even turn it off unless the battery dies. It says at the bottom : "This MIUI version can't be installed on this device"
I'm unable to flash it again using mi flash, unable to unlock it again as it gives me a weird chinese error, that translated, it think it says : "This phone has been used by account 622****418, by looking for phone lock"
Unable to boot into EDL, tried with a deep flash cable(seems it is not supported anymore)
I didn't open it, as I still have warranty(just bought it 3 weeks ago).
USB Debugging and OEM unlock are off as it was just flashed so it has default values.
The account on it is mine, but apparently mi Unlock is not recognizing it. My Mi account has different digits and I have permission to unlock the bootloader since last year.
Is there any way that I can go around this ?
I'm thankful for any advice that you have, guys...
Your device is most likely permanently bricked - when the bootloader is locked with a global ROM on a Chinese Xiaomi phone, nothing can be done to fix it - except one thing.
Are you sure you're booting into EDL mode correctly? I think you need to short two points on the main PCB while plugging in a USB cable. Xiaomi has a proprietary implementation of EDL mode - IIRC you need special Xiaomi software and a Mi account with the appropriate permissions (you can beg Xiaomi for permission on the Mi forums, or buy a working account from someone online). In EDL mode, you can re-flash the China ROM and recover the device.
Most likely, that's what I'll have to do, but I wanted to consume every chance and tutorial online before I remove the Back glass...SO it's Service Center or Test Point with auth accounts, which it's hard to get. I rather pay. Just wanted to make sure that it's bricked from my perspective, like I can't do anything to fix it from my end. Thanks
There is nothing you can do, the bootloader is now locked and you are on a rom that's not matching.
I used the Russian tech reported in one of the other threads about bricked k20 pro, costed me $20 and I needed to open up the phone, and do test point edl which were all easy and well worth it to save the $650 AUD I paid for the phone.
https://forum.xda-developers.com/k20-pro/help/destroyed-error-fastboot-locked-t3946012/page6
just add him on whatsapp and be nice to the tech and he will help you. I saw other posts if you ask him like an ass then he will ignore you.
I definitely don't want to open the phone. If it comes to that, I rather pay someone to do everything with proper tools and software.
You know, try to get in touch with xiaomi support. Explain The case and maybe they unlock it for you from there.

Did you find any solution without edl method? Cause currently I'm facing the same problem.
The only solution here is to go into EDL Mode, if you dont have an authorized mi account, I recommend s-unlock.com they have an automated service and their own tool to flash your phone, go check them out. If you have doubt opening the phone, it isnt hard. Just use playing card first and dont remove it, then find an old credit card to continue further gently.

After removing the back of my phone and fixing it with the help of an awesome dude from Japan found on whatsapp...I tried to unlock my bootloader again, and realised that the account I had in my phone was not the one that I was entering on miUnlock. I couldn't see that because the error message at 99% was in trad Chinese.
Maybe it would've worked if I knew that. If you go into Fastboot and try to unlock it, what message do you get?

Cannot unlock bootloader - chinese error message

Hi,
I've bought the Mi 9T Pro on Amazon.
So far, everything works fine besides the fact that I get an error message in chinese while using the Mi flash unlocker to unlock the bootloader.
Mi account logged in. Since I don't have a nano-sim yet for my main number I've used my spare card to activate it.
Anyone fluent in chinese what might be missing here?

The message says that the device has been locked via the MI find my device service. Is the number your account? If so, you will have to unlock your device first via find my device.

Oh someone can read it.
Any idea how or where I can remove that completely?
Edit: the number is not my primary under which I've registered my other Mi devices. But I've used it once to unlock my dad's Mi Mix 3, which is also registered with my Mi account.

If the displayed account is your account, you should be able to just head to i.mi.com and unblock your own device. If it's someone else's account number, that means someone has marked it stolen or otherwise locked.
Alright, after cutting my sim I continued. After updating the MiUi Flasher I get now errors in English.
New error: "Current account is not bound to this device. Enable it under dev options -> Mi Unlock status."
I did exactly that - I inserted the sim, went to this options, and ticked link to account. fter that I got a message "linked successfully". In fastboot mode in the flasher I get the same exact error again. The phone does not seem to be recognized by the Mi account and is thus not listed in the Mi cloud.
Any ideas what went wrong and how to fix it?

Log in to the Mi Flash Tool using the phone number of the SIM that's in the phone and was used to register the phone for unlocking (when you go to developer settings, unlock status)
This normally happens because the phone number wasn't registered on your Mi account before starting the unlock process.
That was the error, ty very much. I did always login with my email. After the phone number it did show a timer.
PS: a whole week now? No idea why they prolong it each time...

Might have been due to an older version of the Mi flash tool. After I updated it, it was in english. Maybe the older version did not have support for the global Mi 9T and thought I have a chinese K20 Pro.

Error when trying to login to mi unlock tool

Hello, i wanted to unlock my xiaomi redmi 8's bootloader because i wanna install root on it. I completely understand the risks and im willing to unlock it. I don't care if it takes months for xiaomi to approve my mi account. So, when i tried logging in into mi unlock tool with my mi account, first thing i noticed is that its quite slow. Anyway i entered my details when i was at the account login page, and then a few seconds later the page turned white. At first i thought it was just simply loading however after i checked the logs, i see this message: WARNING: account loading error: -188. Ive done some research why it isnt working. They suggested that i should disable my antivirus and run the tool with administrator priviliges. However that didnt help either. Ive also noticed that after i clicked add account and device in mi unlock state, (i enabled mobile data and turned off wifi) it said my mi account had been added. However when i exit out of mi unlock state and go back it says to add my account again. I dont know if thats intentional or not. If somebody can help me i'd gladly appreciate it.
if youve failed unlocking it, your phone is still safely under guarantee, have no fear (IMHO)
i remembered ~2Y ago when i tried unlocking it i was also sent in a loop. i followed the usual guides and all and was also reverified on my phone and PC again. sometimes the mi server can be buggy, and we had to wait for a bit.
make sure your phones SIM 1 (in the middle) has both SMS and data kuota available, as thats how they verify your device and account. IIRC 1 SMS to their servers, and 1 verification data from network to your phone.
I haven't gotten to unlock my device yet. So far i'm at the logging in into mi unlock tool stage. And also yes, i have all of those things that you mentioned.
yep it looks like youre stumped after waiting a day. for references, which guide are you following? does windows and ADB|fastboot detect your phone and driver?
usually an account is verified after a few days when creating a new xiaomi account, and 1 week after using the phone.
from what i remembered that most guides dont state is that my friend told me to locate my device first via i.mi.com first. after locating the device in normal system mode, follow the usual steps. as i said i too remembered how buggy mi unlock can be. hopefully others can also chime in.
my mi unlock tools an ancient 4.5.514.47, newer versions should be preferred for security|bugfixes, but im just saying i unlocked it with that version in case it might help.
Yes mi unlock tool detects my device in fastboot mode. I'm following a tutorial on youtube.
Good news, i managed to unlock and root my phone! I guess i was just lucky because i tried logging from day to day and i finally got it to work.
