Hi, I have already rooted and unlocked my bootloader then proceeded to flash a custom ROM. I want to try out a different ROM so do I have to re-do the whole root and unlock bootloader process ? I know its just flash one simple zip file in recovery but the reason I ask is my phone got soft bricked last time around.

Once it's unlocked you don't need to do it again unless you intentionally re-lock it or get a new phone.
Also be careful if you somehow get vzw OTA pushed to your phone (sometimes happens without you knowing it) it will lock your bootloader again and when you go to flash it will say something about taking your phone to verizon. Don't panic as most people do all you have to do is unlock again and everything will be fine
Hello everyone.
I live in Brazil and I bought at the Aliexpress MI4C Xiaomi. I haven't received it yet, but I've already started researching ways to use it with another ROM than the original. The seller sends the device with google apps and multilanguage option. So, he makes some modification in the ROM, and says to not update the ROM officially on Xiaomi servers.
I see a lot of complaints about the Chinese bloatwares in ROM and so I wanted to install one that was good, but nothing with applications in Chinese or unnecessary ones.
My question is: in this case the bootloader is already unlocked?
In the meantime, I sent my request for unlocking bootloader to Xiaomi and received the SMS containing a link. As soon as I get the cellphone I intend to do the procedure. There is a risk of bricking the phone?
I’ll do appreciate good links with how-to and good ROM to daily use.
Thank you.
The seller shipping a modified ROM and telling you not to update the official would suggest your bootloader will not be locked. For now only flashing the latest official China dev builds will lock your bootloader.
Getting pre-approved for unlocking couldn't hurt though I guess.. just in case. You might need to have a working Xiaomi framework in your ROM to register your phone once though. If your ROM does not have the xiaomi services, I would suggest either Xiaomi.eu or sMiUI as a ROM, both are pretty much stock MIUI with some chinese bloat trimmed.
But most likely you will not need to unlock your bootloader anyway. You will need to check your bootloader through adb anyway before doing the steps to flashing a new ROM. You will best be flashing your recovery through adb, the instructions can be found through most ROM pages or simply searching TWRP Mi 4C. The command to check if it's unlocked is
Code:
fastboot oem device-info
A very extensive directory can be found in the INDEX thread, first in this forum.

you cannot check the bootloader locked or not by that way. My phone when checking this, gets the input "bootloader unlocked: false" but I can flash other recovery freely.
in his case, he is using a modified rom, it means his bootloader is not yet unlocked. Right now, if he wants to come back to chinese rom, he should use Mi flash to flash his phone. If he wants other rom like CM13, he should download the latest TWRP and the rom, put the rom into his phone storage. Then try to go to fastboot to flash the recovery, then go to the recovery and flash the rom.

Ah, that might be incorrectly reporting indeed. In any case when trying to flash recovery, if you're locked it'll simply fail and won't be harmful.
But why would you think his bootloader is not unlocked? If he's using a modified rom, it was probably flashed through fastboot or a custom recovery, both require the bootloader to be unlocked.
But even if he was not on a modified rom, stock Mi 4c have always come bootloader unlocked. Someone would have to have gone out of their way to lock the bootloader and I doubt any reseller would do that, they would risk a lot of refunds from angry customers.
I strongly advise against using miflash to flash any official rom unless you have no choice, since then there's a chance you WILL lock your bootloader. For now only dev builds are locking it, but the next stable release might very well too.
The first step should be to flash TWRP
The second step to stay away from Official China build
The third step to keep away from Official China build
The fourth st...
^ sorry my bad.... I was not focused. Actually I mean his bootloader is unlocked .
The safest way is flashing via computer, using mi flash or flash twrp image. You are right
1. Ur phone not lock bootloader
2. U can flash custom recovery...(TWRP)
3. "MUST" Stay away from official MIUI ROM
4. Flash whatever u want...sMiui, CM13, etc,etc
5. Remember Point No.3
***Btw, download official Fastboot ROM and keep it to ur drive, for just in case if u want to sell it again
Hello. Thank you all. I just received my phone. Great, btw. I'll read again and again all instructions and try. Thanks again!

Even as a last resort to getting your phone working if you did something wrong, please don't install the newer official roms, it's the mistake I did this weekend now I have a locked phone with a rom that has force-closes everywhere and absolutely no way back.

yes, or the safer way is always flash the latest chinese rom via miflash. twrp does not like Chinese roms

Don't flash the latest chinese rom.
No.
The only scenario where you would want to use miflash to flash a chinese rom would be as a last resort to flash the fastboot version of V7.1.6.0.LXKCNCK to restore your phone. Any later version will lock your bootloader.
If you don't care about locking your bootloader and the arduous process of unlocking it, you're easier off just taking all the latest updates OTA via the updater.
Hello everyone. Thanks for the help. In fact my bootloader was unlocked. I flashed twrp 3.0.0.3 and flashed the CM13 teamluminial, Android 6.0.1. Excellent. Thank you.
Hi!
Same scenario here..
I will receive Mi 4c with the Bootloader Unlocked, Rooted and the Multilanguage ROM.
But I have already received from Xiaomi after my request also the number for the official unlock procedure but now I'm a bit confused..
Do I have to unlock the bootloader once and for good with the official way?
Because I've read that the unofficial way isn't so secure in long term.
Do I have to install from the Updater the latest Cina Dev ROM and after that to proceed with the official unlock? Or it is better to use the Fastboot ROM?
Please could some one tell me in any case what to do ?
Thanks !
If you don't flash something that will lock your BL, no need to Unlock.
Ok first I must check the status of the bootloader to be sure that it is unlocked (via cmd control or cpu-z)
And after that can I choose an unofficial weekly miui.eu international ROM and install it?
Can I download and also update every week via Updater this ROM without issues?
At the moment my problem with flashing is that I don't have my pc (the one I have now runs win xp) and I don't want to stuck with the eventually malware or fully spammed modified rom of the reseller..
Which options do I have?

TWRP works perfectly. The backup is simply stored in your internal storage。
im on android 6.0.1 official want to downgrade to lolipop to flash CM 12
and notficition of app like facebook and whatsapp not appered counter or number a notifiction
I believe you need to downgrade to lp before you can unlock the bootloader and install twrp.

how to downgrade and what is the unlock boot loader ?
and when i bought phone what is the default ? that boot loader is locked ?
You may be able to use the Panasonic Eluga software to downgrade to lp.
You must unlock the bootloader to install twrp and cm.
Some info here: http://forum.xda-developers.com/idol-3/development/tool-tools-idol-3-5-5-4-7-t3441781
When flashing anything to any phone, things can go wrong; therefore, I suggest that you familiarize yourself with flashing and be ready in case of disaster.

You can't flash twrp unless the bootloader is unlocked. The bootloader cannot be unlocked on MM, only LP.

Hello everyone!
I bought a mi 4c from gearbest which came with a custom\unofficial possibly full bloatware rom, because of this i decided to install the last version of miui for mi 4c from xiaomi.eu! To do this i had to unlock my bootloader, yes my bootloader was looked because before i thought about xiaomi.eu rom, i had installed the lastest stable chinese rom by using the rom updater which i think that it looked the bootloader when i did this. I don't know if the bootloader was looked or not while i had that custom rom on the phone because i did not check it.
So my bootloader was looked and i wanted to install TWR to install the xiaomi.eu rom because of the international support and because of google services and play store which i had tried to install in the chinese stable rom but i had failed miserably to do so! So i want to install TWR but i did not want to wait for the sms with the code to unlock my phone because i had read people complaining that the code takes a long time to arrive and etc! So to solve my problem i used this unofficial way to unlock my bootloader -> http://en.miui.com/thread-247961-1-1.html <- which worked and i got my bootloader unlock, installed TWR and the lasted xiaomi.eu rom for mi 4c
/\ I regret using the unofficial method to unlock my phone, because two days later o got the sms with the code Haste is the enemy of perfection!
But now i want to go back to stable chinese rom because my phone is overheating and throttling a lot and also the GPS works really bad which it did not on the chinese rom!
Now for the doubts:
1 - If i use Fastboot + Miflash to flash the last stable chinese rom, is there the risk of bricking my phone? Because of the way i had unlocked my bootloader i mean?
2 - Is there way to lock the bootloader again, so i can unlock it the right way? I mean using mi unlock and the code that i've received? It will make any difference using the official way in relation to the unofficial way, it will be worth it i mean?
1. only risk is you have a power blackout
2. you can, fastboot oem lock
Hi! Please I really need your experience
I will receive my new Mi 4c with the Bootloader Unlocked from the re seller , Rooted and with Multi language ROM.
Do I have to unlock the bootloader with the official method (which means flashing Cina Dev ROM -to re lock the bootloader- and go on with the Xiaomi's code procedure..) or it is possible to get all things done as soon I get my device by choosing an unofficial weekly miui.eu international ROM and install it normally from the Updater app but also be able to update it every week via Updater without issues?
My problem with flashing is that I don't have my laptop and the one I have now runs win xp.

1. i suppose no, it will only brick if you have TWRP recovery flashed to recovery partition. My workaround is to never flash TWRP in the first place, but boot to TWRP from Fastboot every time i want to flash something. definitely a hassle but should be guaranteed to work. Never tried though, i am fine with CM ROM and unlocked bootloader.
2. If i read correctly, the latest dev ROM will lock the bootloader back. So if you want to unlock, you must flash the old MIUI version as suggested in the unofficial unlock method again.

you can unlock via unofficial method. Win XP should be able to flash it. CMIIW though
Thanks but it's not necessary anymore ..I've changed the Mi4c with Mi4.
Hello every one. I have a c2105 from Vodafone and I'm convinced that there's no option to unlock my bootloader, but recently, I found two videos on Youtube which show a software that can unlock it when it says "NOT Allowed"...

Has anyone tried one of these softwares and has it a chance to succeed ? :fingers-crossed:
Thank you :laugh:

Flash recovery to boot via fastboot and flash rom and after that flash boot from that rom
There is a way to install a cwm while BL locked. Although in order to flash a custom ROM you need to find a good one and one for BL locked (which there aren't many at the moment)
Can we install rom without unlocking bl
