There are so many people who have flashed dev ROMs ONLY for rooting their mi4c and got bootloader locked.
Stop flashing dev ROMs unless you know what you are doing.
Even with stable ROMs, you can root it with SuperSU using TWRP! If you wanna use dev ROMs without getting bootloader locked, google "eu xiaomi mi4c rom"!!

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.
Hi.
I'm right now on TS CM 13.1 and I want to try the RR. But I didn't unlock the bootloader officially, so I need to do it properly now so I won't end with an locked bootloader.
While I'm waiting for the approval... can I just flash the latest China dev ROM with my current recovery? Or should I flash it from fastboot?
Thank you.
Since you have a custom recovery, try Xiaomi.eu or miGlobe, though be careful as I think latest versions (Android 7) will lock the bootloader. To be safe, I'd flash an older version with Android 5.1 for now.
You can't try RR 5.8.1 based on Android 7.1 as it requires lollipop bootloader.
Or you can flash 6.12.22 and then update to any Nougat Miui Rom available on Xiaomi.eu. This is done via Updater app.

I didn't realise there was a previous RR version with lollipop bootloader.
I already got the SMS with the approval from Xiaomi. I though it would take long. So, if get that right, I should first flash an older Android 5.1.1 Dev ROM and than update it with the Updater app to the latest version with 7.1 . This will lock the bootloader and than I can unlock it officially.
If I do it from from fastboot I can flash directly the latest 7.1 dev ROM, right?
Thank you guys. I always messed around with ROM's with my old GNex, but this Miui stuff confuses me a bit.
No need. Just go in TWRP and see the RR N thread there is a link to nougat blobs. Install that and then install newer TWRP that works with nougat (see android development). I think at this point you'd have to unlock bootloader. Then install room normally
But, as I read in the RR N thread, after I flash those blobs I'll end up with a locked bootloader if I previously unlocked it unofficially. As I did.
And, at least I think, I can only unlock it again from an official ROM. That's why I want to flash Miui.

Whether you have unlocked your device officially or not, it will still lock your bootloader. The key here is if you have the permission to unlock it. If not, then don't proceed. You can officially unlock your bootloader after 5 business days upon receiving the SMS.
Ok. I do have the permission. And can I unlock the bootloader right away with mi flash unlock on a custom ROM or do I need the official miui ROM?
Worked for me with no OS, so I assume you do not need miui.

After you flash the blobs, the bootloader will be locked. Unlock it via Mi Flash. Then flash a Nougat compatible TWRP and you're good to go in flashing Nougat RR.
Hey guys I use a nexus 5x and many people told me that my phone is extremely suited for custom ROMS and it will improve my experience.
1) So I was wondering as to how to flash a custom rom.
2) And my most important question is do I need to root my device to flash a custom ROM and custom recovery or is unlocking bootloader enough.
3) Also if I unlock the bootloader but don't root the device what more can I do with my device.
Any help will be appreciated. Thanks.

1.For flashing a custom rom bootloader must be unlocked and custom recovery is also required
2.this thing depends on you... You can even use a custom rom without root access.many roms doesn't give root access by default..but
3.root access depends upon rom... Many roms comes pre rooted and many doesn't...root access is not permanent...

Thanks buddy. Could you do me another favour and recommend a few non root ROMs which improves battery or gives high amount of customization options
Its my personal opinion you dont need to avoid root access... I am not a nexus 5x user so i cnat suggest a specifc rom..i used custom roms in op2 and op3t so according to that experience i will suggest you lineage, ressuruction remix, mokee, paranoid, dirty unicorn... Moke is battery efficient rom...

I am trying to avoid root because the last time I rooted my Galaxy s3 things were bad after a month. I started to get these apps on the device automatically that were vulgar and also had to deal with a few other problems. Even after I formatted the device , things did not change.
Hello! I'm trying to unlock the bootloader of my OPPO A57 device. With it not running on official Android, but a fork called ColorOS, Fastboot is disabled. I've tried multiple things and have already bricked my device once due to stupidity. I can flash an unofficial TWRP with it but how would I unlock the bootloader so that the custom recovery doesn't cause issues?

These days manufacturers are assholes because if bootloader is locked you're pretty much ****ed. Unless the manufacturer offers a way to do it on their official website, there is nothing you can do. The only real thing you can do is not buy a phone with locked bootloader.

Software: Android 8.0
Build number: 41.3.B.1.197
Status: Not rooted/Bootloader locked
Bootloader unlock allowed: No
Hi, I want to ask if my device here could potentially flash a global rom or any other stock rom variants that could enable me to unlock the bootloader. If can, I want to know which roms are allowed to be bootloader unlocked. I personally dont care if things will be buggy and wont work because as soon as I flash the roms I would quickly flash twrp and flash my chosen custom rom (If I could..and thats one thing again to ask. Can I flash any custom roms posted on XDA to my phone...?). As to why I'm asking this question is that I'm looking to boost my devices performance,latest android version(if possible),prolong battery,resolve heat issues and resolve the terrible wifi signal (keeps disconnecting and poor reception). I hope I've given enough information for this and sorry for the multiple questions asked.:laugh:
Same with my Xperia Z1 but still can't unlock the bootloader if bootloader unlock allowed say NO
yes. you can flash global rom via using sony flash tool
working fine..but bootloader unlock status still says NO
but flashing global rom makes more useful..
