Hi at all!
After yesterdays update over WiFi (don't know which exactly, but I think it's MiUI8 6.9.8) my Redmi Note 3 (Qualcomm, 32GB) wouldn't let me unlock the device neither with fingerprint nor pattern. Before I updated it was normally unlocking. Normally I use fingerprint, so at first I thought i forgot the pattern, but after several attempts the phone went into lock mode. I am 99% sure I know the right pattern, but it won't unlock.
I already read this guide: http://en.miui.com/thread-5684-1-1.html and tried this https://www.youtube.com/watch?v=NMAPEhH5z-8
But I have still several problems:
- USB debugging not enabled
- no recovery installed
- no root or open bootloader or anything like that
- no backup of all photos, which are on the phone itself and not on the SD card (I just came back from holidays)
- no cloud or similar backup
- Mi Pc Suite does not detect phone
- Google Device Manager states "Since Google has verified that a screen lock is already set, the password that you entered won't be needed." if I try the send a new lockscreen.
This method (with flash afterwards) could help me, I guess, but I still would loose everything: http://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
I have absolutely no idea how i can unlock my phone without loosing any data (especially the photos).
Please if anyone has an Idea, help me!
Same happened to me so I restored my backup, once the restore had finished I removed the finger print and pin number (I had read about this on the xiaomi Forum). Then did the update again and this time it was OK
sounds easy, how did you restore the backup?
Before restoring any backup, I suggest you hard restart your phone. long press the power button.
but if I make a Hard Reset I will loss everything on the phone.
Is there maybe a possibility to insert some sort of file or command via EDL mode, that USB debbuging will be enabled? http://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
No not the hard reset. I was talking about hard restart. The phone will just restart.
ahh I see, sorry my fault.
But nonetheless I din't made any backup ever with this phone.
same problem here
my phone redmi note 3(qualcomm 32gb) is also locked just yesterday ! it shows try again after 120 minutes and after the time completed it shows pattern and it will be locked again and shows the same dialouge after trying my correct password ! actually we shoud get forgot password option behind the emergency option ! please do give a reply to me if you find any solution it means a lot to me !
Well I am afraid I can't help you either... after searching for 2 days I found no solution and flashed my phone. so all data was lost...
I have Mi account and managed to unlock mi5s last year.
So now I try to unlock Redmi Note 3 Pro SD, it says my device not supported.
It's it true RN3P no longer can be unlock the official way?
Not really... I just re-unlocked mine yesterday. Try with China Dev rom. I was having issues with global dev and global stable. Unlocking just couldn't move ahead of 50%. But with China dev, the process was completed in less than two minutes on the very first attempt.

I'd add that the Kate version (Special Edition) doesn't have a China dev rom, and there are conflicting reports of unlocking with the newer roms. I couldn't get it to work with the current dev rom (forgot the exact version) and I just yesterday switched back to 6.7.14 and seem to had more luck. I'm still on my 'waiting period' of 72 hours though
The biggest hurdle for me was getting my Mi Account to bind with the newer versions (there's a specific option you need to set under 'developer options'), 6.7.14 doesn't have that & it seems not be a requirement (yet)

Oh okay my bad.... I just assumed you were talking about kenzo.
I guess i cant b really helpful in case of Kate.
I tried official unlock on global stable , Dev roms & was successful make sure to enable developer options hit allow bootloader to be unlocked ( device must be connected to a mi account & locate your device once ) & authorize USB debugging Also disable all screen lock , passwords ; keep device connected to internet switch to fastboot mode & unlock

hello guys...
i was able to get my bootloader unlocked officially....
i tried everything mentioned online but no luck it always gave error to 50 % on the unlock tool and via oem unlocking it mentioned couldn't verify device....
this is what i did...
1st enable dev mode.... make sure you have oem unlocking (only 6.0 and above) enable also usb debugging...
download latest unlock tool ... en.miui.com/unlock
download minimal adb tool .... https://forum.xda-developers.com/showthread.php?t=2317790
make sure you have adb drive (usb driver)
also just be extra caution instal mi pc suite (though i did it without this)
connect your phone
open command prompt as an administrator
move to adb directory.... and type adb devices to check if your device is listed
the type .. adb reboot bootloader
phone will reboot to fastboot screen
type fastboot devices to check device is listed let this window open
open mi unlock tool.....
login it will verify if you have permission if it fails try again eventually it would
click on unlock it would show a warning
now the important part
as soon as you click yes on warning remove the usb cable...... and as soon as it reached 48-50 % (not more than that) reconnect the usb cable
hopefully it would work....
Thanks
Hello.
I've got a new phone in my hands, which is named Xiaomi Redmi Note 4X (Snapdragon one).
As always I've tried to unlock it because stock roms just sucks.
I wasn't able to unlock my phone with Mi Unlock after getting a positive answer to verification via request (stuck on 99%). I've later found here, that this could be caused by trying to unlock my phone on stock rom, updated to MIUI 9.1.2.5 (9. something, not sure about last digits). So I've learned few things, mostly on xda-dev, as well as my homegrown page about xiaomi phones (mostly from this link -> https://miuipolska.pl/forum/topic/9218-odblokowywanie-bootloadera-w-urządzeniach-xiaomi-poradnik/).
Since I cannot put phone in adb fastboot edl mode (it's being seen by pc and adb, after the command it just reset itself, instead of staying in edl mode), Mi Flash does not work in 2018 (not sure why they drop it), I've decided to use fastboot mode and miflash.
Problem is when I enter the program, plug in my phone in default fastboot mode and start the work, after 3-5 sec I get error 0xffffffff with an option "flash all".
My rom (newest version of rom, taken from this link -> http://en.miui.com/a-234.html) is unpacked twice (to version with "images" folder), I've set it on my C:/ drive in catalogs without any blank spaces between the letters (these things made by clicking space button).
My phone is successfully connected with my mi account (I'm using it since I've got Mi Band2, so it is not so fresh).
My MiCloud synchro is online and up to date. I cannot make verification of that account, however (I'm not a bloody Chinese and I just do not understand their letters and language), but when I checked my account on PC, I've got 100 points (max) for security.
My phone, mail address and phone number are all known to our Chinese friends.
Debugging USB is also not a problem since I've double checked all of that.
I also tick the option for changing bootloader or OEM (somewhere over there in dev options). I even get extra permissions for debugging, that requires triple clicking "ok", due to the danger of being tricked by some skilled hax0rz.
I even deleted my extra security unlocking (both fingerprint and X letter made from dots) to make sure fastboot unlocking will work (this could have been the case in some...cases, as mentioned here -> https://forum.xda-developers.com/redmi-note-4/help/bootloader-unlocked-99-stuck-progress-t3651303).
What else could I do to make sure my phone will be finally unlocked and rooted? I cannot do it with a locked phone, I cannot install TWRP on a locked phone (which prevents from getting root access). To get an unlocked phone, I need to install custom rom. To get a custom rom I need to install it via fastboot. Since I cannot do so, I'm stuck (if I understand it correctly).
I've checked *.txt file in a main rom folder, it's said "mido", and given version is 8.1.2.5 from 25th of January 2018.
Thank You for any kind of help, I've tried to download it for the second time (somehow, the names of the archives are different, but I'm not sure if that could be the case).
Also, this information might be needed – my phone is Redmi Note 4X 4/64, so I cannot use rom for 3+32GB, which is listed there also.

How long has it been since you applied for permissions? I've had the same problem (stuck at 99%) but i casually waited. If it has been more than 3 weeks then try applying again. There isn't any workaround other than using mi unlock.
What do you mean that xiaomi dropped mi unlock?

I've been waiting for...24 hours? Maybe some more. At first, I even gave them a wrong model of my phone (lol), then I've tried for the second and third. For some reason, when I changed my Xiaomi account name to my full name and surname with "_" sign, they refuse to request to go through. But with only my name (I've assumed that there are so f...ing many Rafals on the entire world, they wouldn't know which one is it) it went well and I get the code really quick (less than 24h).
I've read somewhere yesterday (don't remember now) that Mi Suite (which could be used for older phones) is no longer supported. It failed to seen my phone with stock rom, updated via OTA to MIUI 9.2.1.0 NCFMIEK, says that I need to upgrade my phone (lol x2). But mi unlock works fine, apart from that 0xffffffff error. If I've typed about Mi Unlock that it sucks, it was my mistake.
Also, I've noticed, that pack changed since yesterday and devs added new pack from 1st of Feb. It also came with a different name, so maybe that was the reason why I was confused.
OR, now that I'm thinking – I'm not able to properly use MiFlash, since less than 48 hours passed by since my last 99% try on Mi Unlock? Could it be the case, when I do not need to log in in first application?

Hi, first i feel your pain and can associate with you, had similar problem with unlocking bootloader. I had stuck 99% issue.
Try few things, wait at least 5 - 7 days to try again(i know, waiting is pain in a** but you need to do that). When you get approved for unlocking its unfortunately doesn't mean you can immediately unlock you need to wait few more days to be "recorded" on xiaomi severs.
Meantime, have logged mi account, feel up all details in miui account info section in your phone. Enable micloud, make sync atleast once sms/calendar/ call history etc. Make atleast one complete system backups into micloud.
Also crucial part is to have mi "find device" features enabled on your phone, you can freely disable after when you succeed with unlocking.
Log into your micloud on pc(not on phone browser), be careful where you log in, you need to login into English micloud site if you made miui English account.
When you are logged in go to find device feature on site, check if you can see own phone on theirs micloud map.
Check on micloud if you have maybe more devices linked, if you wish you can remove other phones and live only your redmi note 4.
After atleast 5 days, try again but this time, do crucial steps: find device enabled, go to miui English site, log into account, on main page near "unlock" section is "download" section, click and download mi unlock tool.
Stay loged into miui site on pc, run unlock tool and try again.
I had issue with unlocking, after doing all of this managed to finally unlock bootloader.
In short:
You need to wait few more days(5 atleast). Fill all details in miui account on phone and do also on miui site/forum account.
Sync your phone, make backups on micloud.
Enable mi cloud find my device service on phone.
Check if debugging mode is enabled and oem unlock turned on.
Remove pin/pattern lock and fingerprints unlocking feature.
Be logged in on mi account on phone, also on pc browser.
Try to unlock it.
Ok, so after this cool reply I've got two more things to consider:
1. Checking that locate my device feature – done. I've got this option enabled on my RN4X, but I've not checked it on my pc. Now it's done, and I'm remembered (I hope so) on the page with localization feature.
2. Being logged on pc page when unlocking using Mi Unlock. Isn't the logging in this app enough?
Also, one more thing – how do I check, how much time I need to wait before next unlocking try? Mi Unlock does not show that (amount of hours, that can be seen on unsuccessful attempt). And I do not want to screw something up. Quick checking my account for permissions to unlock has been done successfully since no errors were shown.
E: I've already added my account (with mobile transfer and wi-fi at the same time, so it has to be sent!) on programming options, under the "Mi lock status" or something like that. I don't think that spamming this option will change anything.

1. Have it enabled till you successfully unlock bootloader. Please, check if you can see your device on micloud map. Also check how many devices are linked to that micloud account.
2. Not 100% sure do you need to be online in both, but it helped me.
No need to spam that "mi lock status" button.
Don't forget to make some system backup on micloud and aditional sms/call history etc.
Also fill up account details on your phone under "mi account" section.
About time to pass, so you can try mi unlock tool, isn't define... Unfortunately there you can't be sure when you will be in chance to successfully unlock bootloader... That's xiaomi philosophy, they don't want procedure to be easy and smooth ride.
Some rule of thumbs is to wait atleast 7 to 10 days... I tried after 5 days again.
I hope this info's helped a little.

Yes it is. I've seen myself on map in pinpoint location, so they got it right. There's only one device (RN4X), so no need to be bothered.
I've already made a backup and trying to have everything as much up to date as possible. Most likely I'll end up with few hours of configuration anyway (due to highly custom apps of mine, I just dislike things like default gallery, default music player, default homescreen etc).
On my phone everything is fulfilled (apart from verification, but I'm not a Chinese and I will not be able 2D so. I'm not gonna give them my ID scan (they didn't recognise it anyway, so xD) or my account (they say that it's not supported anyway)).
Now I just need to wait 2 more days, since there might be 72 hours delay (according to this site -> https://miuipolska.pl/forum/topic/9218-odblokowywanie-bootloadera-w-urządzeniach-xiaomi-poradnik/, point 6.5. and "quote" box) between getting permissions and actually being able to do anything.
Not sure, why Chinese are doing such weird things with their stuff. Even UMI C Note (which has next to nothing support on internet) or QCONG C1391 (I'm gonna root it soon) are much easier to bypass. Even with Mediatek. I don't get it, but if I bought it, I'll have to live with it, right?
I'll most likely come back on Monday to try it harder again. I also knew now, that MiFlash is backup option, in case of my phone being dead. Knowing my skill and troubles with android phones since old LG GT540 I might need that knowledge later (hope not, but still). I actually never made a proper flash from the begging until the end in first try with guides. RN4X is just another example of that xD.
I'll post my next results there soon.

Agree, xiaomi complicating things to the maximum and they aren't alone. Most popular excuse is that locked bootloader = secure device, but i like to have choice to have less secure but complete control on product which i payed.
Forgot to say, someone also mentioned that you leave phone on and connected to Internet when you run mi unlock tool and signing into account on mi tool and then you connect phone into pc usb port when tool ask you.
Whish you luck with it and you're welcome to post how it went after.

Ohh man, yes mi suite is really like (un)useful, i mean it never detected my device. Well it's been only 48 hours? Wait man, just wait. Xiaomi sent me a Chinese email with the dl link of mi unlock in 3 days, but the actual server sided permission, (without which you get stuck at 99%) came to me after a week. And I just noticed it when i like casually thought that, let's see if it works. Andds BAMMM it did. When the permission is granted it is 35-50-75-90-99-100% with no pause at all. So the thing is wait. Check out some guides till then, so you can prepare yourself to make mido the ultimate device lol

Do You mean chinese language mail to your mail connected with mi account? I didn't get that one yet, I didn't even get any permission other than sms.
It starts to look like one of these memes in web, which said "OP will surely delivered, I'll just wait", together with skeleton in front of the PC.

Once again, my mistake – got it two days back, before I even started "fun". I'll try to unlock using MiUnlock again on Monday.
I've tried again quickly this time, just to see if any of that "wait a bit longer" is true.
It is done. My phone is unlocked. I can also still unlock my phone with my finger (not always works as I desire, but it's a big step forward compared to UMI C Note), also "find my device" doesn't seem to bother me with texts such as "oh no, you have unlocked the phone, we cannot help you anymore, blahblahblah". Not sure why Chinese typed warning about it, when it still seems to be working just fine.
This topic is as good as closed then.
Thank You kindly for help, not for the first time my lack of patience gave me (not so hard, but still) hard time.
Now it's time to get some fun with TWRP, root and might as well new rom (because now I can).
hi!
after reading all related post in this forum and searching google for ages, i am still not able to unlock my z5c's bootloader. it is not a lack of skills or know-how - i have successfully unlocked my z1c and z3c - but this one simply does not unlock.
i have tried both windows and linux, used shell and flashtool, all drivers properly installed, phone is correctly recognized, bootloader unlock is positive, oem unlock and usb-debugging are activated, phone is in fastboot but i still end up with error "command did not succeed". flashtool additionally shows "oem unlock not activated?". it is, but doesn't seem to have any effect.
i also tried to include the .txt file with the unlockcode into flashtools filestructure: flashtool does something but can't finish the unlock proccess and my phone is not resetting.
i even tried those one-click unlocker without success.
and there is something fishy about this phone: three month ago i got it brandnew from a vendor in china via ebay and first thing i did was connecting it to the pc companion to upgrade the firmware which was 5.1 and it told me, firmware was up to date... so i tried the repair option and it told me "that due to it's prototype status it can only be upgraded from certain ips" - although the phone does not show any hints of being a prototype, neither software- nor hardwarewise and even if it was, it wouldn't prevent the bootloader from being unlocked (afaik).

Hmm... Possibly not the solution but have you tried enabling "Unknown Sources" as well?
Another thing is - you can try flashing a later version of the firmware with Flashtool - one that is common. Afaik there are some versions that have trouble unlocking. Try flashing something like Nordic Unbranded, boot it up, make the settings again.
P.S. Flashing does NOT remove the old leftover firmware - it just writes on top. So you should format the partitions (/system, /data, /cache, /dalvik-cache) before flashing in order to start clean.
when i couldn't upgrade the firmware via pc-companion i used flashtool to flash 7.1.1 (some german version) which i kept ever since. so flashing a different firmware before unlocking is something worth trying? i thought of this as well but never actually tried it because i was just too lazy going though all the setup process again if the attempt failed just like the others... but i'll give it a try then!
and thanks for the input!
Hy,
For me i had to make two steps :
- Flash a non-branded firmware from Xperifirm
- Network unlock it (actually for me it unlocked automatically at the end of the warranty ). This step it is critical (as i was informed in the Sony store)
Then the normal cmd command through adb worked fine.
Basically for me the network lock / warranty was the issue that prevented me to unlock the bootloader
thank you very much for your Input! but there is no network lock...
what i was going to do was flashing a different firmware and try again - and there is something else i didn't think of: the usb2 connector of my mainboard is blocked by an infrared device to power up my pc by voice command via alexa and a harmony hub. and to still be able to use the front usb ports of my case i connected them with an adapter cable to a free usb3 socket on the mainboard…
so it might have been the firmware, the usb2 port on a usb3 socket or prototype-status that caused the trouble - but i'll never know cause basically i'll give up on that phone since more issues occured… i contacted the vendor yesterday and it seems i'll get a full refund!
i now got my hands on a shiny new galaxy s7 and hopefully i'll experience the joys of oreo 8.1 and lineage 15.1 anywhere soon without the hazzle!
thanks again for your help and regards,
andi
