Yes. You would need to achieve a certain status on their forums in order for xiaomi to approve your unlock request. The most interesting part is that once approved, you would need to wait for their SMS containing the unlock code for you to actually unlock your device which may take 15 days or more according to the some of the users who tried unlocking.

Honestly, I could care less about xiaomi locking their system as long as they provide a way to unlock it without waiting for days.
[Xiaomi Mi 4C] person_x:
Exactly my thoughts... They could learn with HTC for example.
[Xiaomi Mi 4C] gxg:
yes, when you're active in en.MIUI forum, your status will raise with the nr. of posts, and time spent in forum.

Just take your time, read the threads in Mi4c area for example, reply within forum rules (at least say thanks, and dont spam) .. and you can raise your status in a matter of hours.
[Xiaomi Mi 4C] Logic_:
So for now, the only people affected will be the people that deliberately flashed this one dev build (perhaps not deliberately locked their bootloader in the process, but this can only be a manual flash from what I gather). So for now it suffices to stay informed of what builds would lock your bootloader and you can enjoy your unlocked phone without hassle, forever.

But I assume this dev build could soon enough transfer over into the latest stable, which people on stock builds in China would get OTA? (please correct me if I'm wrong here, I don't actually have the phone yet)

If so, that's a scary thought, manufacturers remotely locking down your phone.

It also seems like an unsustainable unlock process if they're moving towards a 100% locked userbase. I can't imagine this to persist very long into the future.
[Xiaomi Mi 4C] gxg:
Starting 6.1.14 Dev rom and probably future Stable rom, every update released by Xioami will lock your bootloader. Sad part is that you can unlock it only after 30 days passed since your last Unlock. = each and every 4 updates

Changing Miui forum ID will not work, as the unlocker will know that is not original account.

Basically if you lock your bootloader and you want new roms... you are stuck with your unique ID from forum...

IT is better for the one's who didn't updated to 6.1.14 to stay on their rom's, and users with Stable rom to update to Developer 6.1.7(11) rom..latest rom released without bootloader lock inside. This way they will avoid the next stable update who will lock the bootloader as well.

As far as I understood, it's an good rom with good battery life.

People with custom roms, and the guys from xiaomi.eu are working to solve the problem of future updates, removing the bootloader lock key.

is there any way to unlock bootloader in fastboot? I am in a boot loop and forgot to unlock oem previously
[Xiaomi Mi 4C] ice-it:
Only for the beta tester of Mi 3 W/C, Mi 4 3G/4G and Mi Note, i suppose
[Xiaomi Mi 4C] ice-it:
You can find the link to en.miui tutorial in the first post
[Xiaomi Mi 4C] ice-it:
you need to allow the unlock from developer options first, so as far as i know you're screwed...

maybe ask in the correct device section, cause the unlock procedure is different for Mi4c...
[Xiaomi Mi 4C] jonasb_dk:
Yes, but I think it's annoying that you need to be an active member of the MIUI's forum in order to "deserve" to be able to unlock the device. That said, the forum is pretty informative although a little messy ;)
[Xiaomi Mi 4C] Andiii:
May somebody please share the latest China Dev (rooted) fastboot image with an unlocked bootloader?

[Xiaomi Mi 4C] person_x:
I've read this from some user on MIUI forum before but I cannot find the post. Sorry again for taking the credit from someone but I believe this may be useful information for a lot of users.

For everyone which unfortunately is on 6.1.14 just download the stable ROM V7.0.16.0.LXKCNCI and flash it through the updater. The bootloader will then be unlocked. After just flash Cyanogen or MIUI from xiaomi.eu and run away from the official ROM :)
[Xiaomi Mi 4C] Ulver:
Here ya go, I uploaded it to my Google Drive. This is 6.1.7 China dev ROM.

[Xiaomi Mi 4C] johnHooke:
this sucks big time... i just ordered my mi4c on the 14'th this month... hope i dont get a locked device..chances are slim but one can only hope. anyway i was planing to go with cm or other custom roms so once rooted i wont even consider trying miui anymore...
[Xiaomi Mi 4C] Logic_:
I'm in the same boat man, bought it the 14th, 12 hours later this news gets out.

I think depending on your reseller you have a fairly good shot of getting it unlocked still, especially if it was shipped the same day.

If not, then hopefully what person_x read is true and you can flash an older stable build through the updater (so without having to unlock) to regain your unlocked bootloader. The hassle you're meant to go through to unlock is just unreasonable so there's no way this situation will persist for long. Either a solid workaround is found or miui budges.

I'll probably give the miui ROM a shot, I've not seen it in action since v1. Chances are the reseller flashed the EU rom as well so I might give it a week or so at least.
[Xiaomi Mi 4C] Finners:
Where did you buy from?
[Xiaomi Mi 4C] Logic_:
minideal.net because it was simply the cheapest.

We'll see how shipping goes, I'm not super confident about the company but luckily Paypal allows you to take those risks. And it's all the same hardware so for now it's a waiting game to see how I get it and what's on the phone.
[Xiaomi Mi 4C] cowithgun:
Unlock via installing the stable ROM will work. I have tested it. I am now on CM13. Everything work fine, GPS, Camera, etc. Overall snappiness improved, right out of the box.

Previously, with MIUI 7, I have to disable so many packages, Mi Accounts sync, configure thermal-engine-8992.conf, switch and tweak CPU Governor, etc, just to get it working the way I want.

No more. Just switch to CM13. :good:
[Xiaomi Mi 4C] johnHooke:
Thats what people say. I would not update in your shoes. :D

Pffff i didn't know about minideal... I ordered from gearbest... I will wait a lot more to arrive... And the price is just a little more than what i payed...
[Xiaomi Mi 4C] Logic_:
What pushed me over to minideal was that they bundle with a tempered glass protector and case and also the option to bundle with the nilkin hard case was cheaper than the other combo's I saw (it might be cheaper ordered separately somewhere else but not enough to warrant the extra hassle). Because I read the back can feel a bit slidey I had my mind set on this case, which is supposed to have a good grip.

I also just found minideal, so I don't know about shipping. Seems like people on average say it's pretty fast for free shipping. But tracking so far is taking a long time to show up, which isn't a very good sign. See what they say on monday..

[Xiaomi Mi 4C] gxg:
Nu trebuie sa-ti faci probleme! Do not worry!

Your phone will come with some old ROM. Immediately after you receive it, flash TWRP, then any xiaomi.eu Roms for libra and you are away from danger! Just don't flash any official updates.

Please read above... same apply's to you too!

depending what rom you have. Smiui will take xiaomi.eu rom's as base. But it's better not to mess them. Just denny the update.
[Xiaomi Mi 4C] :
will the locking bootloaders apply to redmi note 2

is this for global or CN ROM

is this for stable or developer ROM

and what about s MIUI ROM- will they also lock bootloaders?
[Xiaomi Mi 4C] Logic_:
Pretty much all your questions are in the first sentence of the first post.

For now that's the only rom they released that does that.

No other rom developer would release a version that locks your bootloader.
[Xiaomi Mi 4C] :
The same method will be ported on other Mi devices gradually.

from their site

so seems like their "knox"........
[Xiaomi Mi 4C] Logic_:
Yes it seems like this marks a change in policy for them. Locking bootloaders makes sense for manufacturers, it protects the from liability from people damaging the phones.

Whether or not they listen to their users and provide easier and better ways to unlock remains to be seen. Also for how fast they implement this in other roms.
[Xiaomi Mi 4C] :
so can one hope that sMIUI roms (which seem to be based on CN developer and stable MIUI) will avoid the lock bootloader issue?

(reminds me of the days when we worried about knoxed bootloaders at samsung.

have not had a samsung in some time wonder how that issue is going.........................)
[Xiaomi Mi 4C] LineArc:
what about the google play services, I mean international roms, will we still be able to run that.
[Xiaomi Mi 4C] gxg:
There is no international ROM. Not officially. Not for Mi4c.

All the rom's who have more than China and English language inside are made by 3rd party enthusiasts and fan sites.

If you use Smiui (based on Xiaomi.eu rom's) you will not Lock your bootloader.

For any other rom's, please head's up to respective developer page and seek for yourself if that respective rom will lock your bootloader or not.

AGAIN:

Xiaomi. eu managed to remove the lock in the last 6.1.14. Same to S-MIUI who use xiaomi.eu as base for their rom.

For future..we don't know what will happen.

But for the moment .. ask Trice.. flash once!
[Xiaomi Mi 4C] :
so will this ROM Author: MIUI Official TeamVersion: V7.1.1.0.LHMMICK (MIUI7) be one of those that locks the bootloader?

from what i understand this is L (lollipop) HM (most likely code for Redmi Note 2/Hermes) MI (global as versus CN China) ROM but official MIUI/

(have not figured out the CK yet.................)
[Xiaomi Mi 4C] Logic_:
No man, they haven't started locking bootloaders on the Note 2 since you last asked today.

If you do go downloading the official rom somewhere in the future, then it's worth carefully reading up on before flashing.

Hi guys

After whole day fighting with install recovery ( one time was TWRP one time was MIUI). When i finally had TWRP touch was not working....

But ok i think finally i install Smiui rom but i didin't know with version i should chose thats why i install the same with i have rom that's mean LXKCNCI.

Now my question is: can i update via OTA that rom becouse i see is something avaiable....

But im worry about bootloader :confused:

[Xiaomi Mi 4C] Logic_:
No, that's the official rom being pushed. You'll be in some trouble if you flash that over smiui. I don't know if you can disable the updater app or anything (not had the chance to try yet), but smiui never comes ota.

Just keep an eye on their page for new roms if you're interested and you can dirty flash those versions incrementally, normally without issue. Backups are always smart before any flash though.
[Xiaomi Mi 4C] miguelAr52:

That works until you flash a new buid of sMiui, then you have to repeat the same procedure
[Xiaomi Mi 4C] qtotter:
hi guys,

i ordered a mi4c recently, and am learning a bit about this phone while waiting for the package to come.

what i don't understand in reading this thread is, only burning a recent dev rom will lock the bootloader or burning a recent stable rom also will lock the bootloader?? as for locked bootloader, can you still run "fastboot boot xxx.img" command in bootloader mode?

i am looking at updater-script in the full rom now. can you stay unlocked if you comment-out the following two lines in updater-script when burning a new dev rom?

package_extract_file("firmware-update/sbl1.mbn", "/dev/block/bootdevice/by-name/sbl1");

package_extract_file("firmware-update/sbl1.mbn", "/dev/block/bootdevice/by-name/sbl1bak");

thanks.
[Xiaomi Mi 4C] leledumbo:
DON'T do that! MIUI requires Updater app to be exist and alive. Otherwise, upon next reboot you will be kept asked for account and password but your connectivity is disabled which means a deadlock.
[Xiaomi Mi 4C] Logic_:
For now only the official dev roms come locked, but this will soon enough carry over into stable. The safest is to stay away from official and go with smiui or xiaomi.eu roms, if you want stock experience. Locked bootloader won't let you execute commands.

Removing those lines will likely cause the flash to fail, unsure what effect they'll have on locking process.
[Xiaomi Mi 4C] miguelAr52:
ok. thanks you.

luckily, as i don't not know enough about freezing apps, and don't know what else is affected when i uninstall a system application, i only disabled the notifications
[Xiaomi Mi 4C] Prettygrim:
please look at the link below and see if anyone can offer a solution to me, please? i got this particular link via ice-it, so many tnx for that. my predicament is described pretty much in the link

http://xdaforums.com/mi-4c/general/miui-eu-weekly-builds-t3236773/page7#post64948736

i would be most grateful if a solution is found and if there is, i am able to follow it. i also wanted to know how to stop auto updating, because even though i was of the opinion that i had turned that off, the damn phone went ahead and updated both last week and this week anyhow!!

i have downloaded the rom from the link on the first post. what method was used to get it flashed on to the phone, please? having given the problems i am having, i doubt if it'll work, but worth a try. tnx for that
[Xiaomi Mi 4C] qtotter:
Thanks for the info. I'm thinking about burning cm12.1 or cm13 on mi4c right after receiving the device, but I'd like to update radio first before burning a custom ROM. Unlike Nexus, Mi ROMs look complicated...
[Xiaomi Mi 4C] Prettygrim:
well, i tried to get the rom above and a couple of others on to the phone, but absolutely no luck at all! what is also annoying is that i cant even get into recovery option of the phone either, so this legitimate function of the phone has been shut/removed or something. i fail to see what good this is doing. i am so cross with Xiaomi. i'll never purchase another of their phones. they used the 'unlocked' in the adverts to please geeks when it pleased a lot more than those people but then force a rom to install that removes the 'unlocked' option. i think i stated earlier that i thought i had turned off the auto update feature, but i obviously hadn't because the update had been pulled down without me telling it too and as soon as i rebooted the phone, it was installed and messing things up. people should have the option of whether to download and install new roms, especially when a function is removed by the maker. the excuse used for doing this is 'to secure data, to ensure that no one can get into the phone who shouldn't be able to. crap excuses on there behalf trying to justify what they have done and there are other options for people to use to protect themselves anyway!not impressed with the way customers have been treated at all!!

as for using the smiui or xiaomi.eu roms that's fine if you can get one on the phone to start with and stop the phone from auto updating in the first place!

tnx for trying people. if a solution is found, i would be most grateful for a heads up

[Xiaomi Mi 4C] Pumpino:
I've got the Redmi Note 3, so my bootloader has always been locked. I applied for it to be unlocked 11 days ago. Does anyone know how long it's taking now?

The MIUI forums don't tend to promote useful discussion, and there's no Note 3 forum on xda (why is that?). Maybe someone could answer some questions for me.

Does flashing twrp and supersu to root require an unlocked bootloader, or is it only recommended due to the risk of soft-bricking?

Will having twrp installed prevent the successful installation of OTA updates? If so, can full dev ROMs or updates be flashed in TWRP?

I mainly want root to reduce the DPI.
[Xiaomi Mi 4C] qtotter:
For flashing twrp, the bootloader needs to be unlocked. For rooting your device, it is not mandatory.
[Xiaomi Mi 4C] Pumpino:
Thanks. Is there a safe method of rooting the Note 3 without having twrp?
[Xiaomi Mi 4C] qtotter:
I was talking generally. Rooting on an locked device defers from a device to device. Just google.

hi. is it still safe to flash dev rom 6.1.7 ? hope it will not lock bootloader. just got my mi4c today. i want to flash dev rom for root acces and then twrp. thx

LE: nevermind. i followed the tutorial here http://www.beritahuaja.com/2015/10/how-to-root-xiaomi-mi4c.html?en

worked fast and smooth . :D root and TS CM13 .

thx for all the info i found here guys
[Xiaomi Mi 4C] Logic_:
Yeah I also didn't need to flash a dev build to get root. The unlocked bootloader it comes with just lets you push a recovery through adb, the default way. I had read many times that you needed to flash a dev rom first but once you get twrp on there you're good to go :D

For what it's worth mine took quite some time to arrive as well.

It came with most Chinese apps removed and full language support. Honestly it seemed like a perfectly good functional rom, charging on it even seemed markedly faster, but that's hard to tell. But it had a weird build number, one you won't find much info about and some link it to spyware, so after looking through it a bit I decided to flash the stock rom.

Most importantly, it came with the default recovery and bootloader unlocked, which makes flashing new images simple as ever.
[Xiaomi Mi 4C] johnHooke:
Mine took 16 days to arrive but it has worth the wait . also had a strange miui number, like 55.11.99, so i changed it imediately. i like it till now. i am testing cm12.1 . cm13 didn't work for me.
[Xiaomi Mi 4C] ice-it:
Unlocking procedure now in English, check the first post...
[Xiaomi Mi 4C] qtotter:
There are so many people who try dev ROMs only for rooting the device...

Anyway, Xiaomi might release OTA updates for stable ROMs with locked bootloader in the future as well. Personally, I guess the possibility is high.

People who want to keep unlocked bootloader should stay away from official ROMs and install xiaomi.eu ROMs or other custom ROMs such as cm.

Most companies expect users to use their devices as shipped from factory or officially updated. Not many companies recommend users void warranties. As for this case of Xiaomi locking bootloader, they should have announced widely before proceeding this policy change.

Glad this mess happened before my mi4c arrives although I'm sorry for the guys who got their bootloader locked by accident.

Watching on miui.com forum, it looks like many people even with diamond status are rejected for unlocking approval after waiting for weeks. I applied for approval just in case, but my chances will be really little...
[Xiaomi Mi 4C] Pumpino:
Mine was rejected, and there's no way of re-applying. I won't be buying Xiaomi again.

"No soup for you. Come back one year!"
[Xiaomi Mi 4C] qtotter:
A bootloader unlock tool for redmi note 3 was developed (because of mtk?) in xiaomi.eu. We might have a chance??

Anyway, you can apply for approval again later. I'm sure Xiaomi would change the process if many skilled users complain a lot and stop buying their products in the future. HTC did a similar thing, and we all know what has happened to HTC...

just wanted to update you all.

i received a txt message this morning at about 11:30. the message had been sent at 18:00 on 30/Jan. it told me that i had been given permission to unlock the bootloader on my Mi-4c! i was very happy until i read that the permission was only valid for 1 day! anyhow, i went ahead and successfully unlocked it. that was when the issues started. i couldn't get into the phones settings to alter anything and i had got no keypad. this is something i reported after enforced update 6.1.21. anyway, after pulling a bit more hair out, i found that i had done a backup of the phone before the lock happened, and had forgotten. just as well, because the phone is now working as at least it was prior to the lock. the downside is that it is an official rom, miui_MI4c_5.12.31_5d6537a0b8_5.1.zip. i really want to get an eu miui unofficial rom on to the phone to remove any possibility of getting locked out again. which rom is recommended and what is the procedure for installing it safely?

would welcome ahy help

TIA

If you wanna stay in Miui you can use sMiui or Xiaomi.eu Miui, both don't lock your booatloader and can be flashed through TWRP
