New User - Help with unlocking bootloader - please read - Xiaomi Redmi Note 4 Questions & Answers

Hello. First let me explain my situation.
So, today i bought a used Xiaomi Redmi Note 4 (SD)
I have a problem. I dont know if my phone is unlocked. When the phone is booting up, on the bottom it says unlocked, then it changes to powered by android.
Last year i had a Xiaomi Redmi 3 which i unlocked myself.
I downloaded the MiUnlock Tool from the official website, when i signed in it was authenticating my account with success (I dont know if i should ask for another permission for unlocking, as i already asked for permission for the Redmi 3 a year ago). When i clicked unlock, first time it went to 50% and it said with green Phone already unlocked. When i clicked unlock again it said unable to recognize phone error 1, or something similar to that, i did chech the drivers in the program, everything was fine. I tried that two more times, same problem.
In developer options in the 'MI unlock status' it already says 'unlocked'
The questions:
1.How do i chech if my bootloader is unlocked ?
2.If it is not unlocked, do i have to ask for permission from Xiaomi ? If so, how long is the waiting time (i heard that now its longer than before)
3. The phone is with Global MIUI firmware. Do i have to flash chinese developer firmware ? And for that does the bootloader to be unlocked, or its a step that has to be taken in order to unlock the bootloader ?
I searched on some subforums buts its been a long time since ive done this, so i thought i'd ask here.
Thanks in advance. Sorry for the long post, but i hope you'll read the whole thing.

1.It seems that your phone is already unlocked. You can check it like you already did; under developer options and startup.
2.I heard they gave up the 'permission to unlock' procedure. Not sure though. You only need to unlock bootloader when it is locked.
3.You should flash the global developer rom. Firmware is included. Although you can also flash the China version if you want.
I would flash the global developer through MiFlash tool and after that twrp and possibly some custom ROM if you want. When flashing custom roms, you should always check for the newest firmware before flashing and right after wipes flash that firmware before rom flash. https://www.google.com/amp/s/forum....nt/firmware-xiaomi-redmi-note-4-t3760917/amp/

Kate (International Version): TWRP/root/roms?

Hello, various posts say kenzo roms could be used on kate, but without modem files. Many users already tried flashing manually modified roms, bricking or having issues. Is there a full tutorial to how effectively:
- unlock bootloader (only unofficial way for what i understand...)
- root the phone (only flashing supersu via TWRP? what version of TWRP?)
- possibly modify existent kenzo roms to use them on kate (not only CM.... there are so many roms with various kernels too...are they working without problems on kate?)
so far i've been scouring the net for any possible guide, but there are really few to none specific for kate, and none answering clearly the previous questions....and i am sure i'm not alone as more and more people are buying right now the international version, and keep asking the same questions. Could somebody shed a light? thanks.
Following this thread. I bought international version and can't wait to flash CM

You need to unlock bootloader and then flash TWRP. Once that's done all you need to do is flash CM13, CM13Firmware, Opengapps ARM64 and modem file for Kate (NON-HLOS from fastboot of MIUI8 Kate). Also can flash latest SuperSU for root.
To flash modem once CM13 is installed boot fastboot and then enter:
fastboot flash modem NON-HLOS.bin

Is it possible to just install twrp and supersu and use miui roms?

I wish there was a TWRP specifically for "kate" though. Because TWRP will think "kate" is "kenzo" for now.
is its possible to unlock the Kate version on the official way? Because in the Guide from Xiaomi ist the Point "You must on China Dev Firmware" but this versions isnt available for the kate version?

Until today, no one confirmed to have had success with official unlock. Even though it should be possible to unlock with the Mi Flash Unlock tool on every ROM, it is very likely that it can only reliable unlock when using a Chinese Developer ROM, which doesn't exist for Kate.
Most people are getting an error message in the above utility, saying that the MI account in the phone and the one used in the utility don't match, even if they do.

You found my guide.
Is there any good reason to wait for a reliable way to officially unlock the bootloader? Or any downside to go with the unofficial unlock method?
I got my phone yesterday and just found out today I actually had the Kate version. I don't really plan on going back to MIUI and from what I understand, the official unlock method would only make it easier to switch back to MIUI. Is that right?
(It's not my first time playing with custom ROMs, I have flashed multiple roms / kernels in the past but I always owned Nexus phones and it was quit dummy proof on these phones.)

That's my understanding, yes. Interestingly, when I had a Kenzo and unlocked it officially, the bootloader got relocked whenever I flashed something like CM. With Kate (unofficially unlocked), the bootloader wasn't relocked after flashing CM. In that sense, unlocking it via unofficial means may be advantageous.

Thanks Pumpino!
I just followed your guide and successfully flashed CM 13 stable release without any issue.
It's only been a few minutes but everything seems to be working (much better than MIUI) so far.

You're welcome. I'm glad it went smoothly.
I've just edited my previous post, as "was" should have said "wasn't". ie. "With Kate (unofficially unlocked), the bootloader wasn't relocked after flashing CM."
Followed the guide and can't get the bootloader to unlock. Any ideas?
Downloaded the updated/modified emmc_appsboot.mbn, put it into the rom folder and flashed fine. Won't unlock.

I made a mistake at this part and it wouldn't allow me to unlock the bootloader. The guide to unlock the bootloader doesn't explicitly mention one important detail. In the screen where you have to allow USB debugging, you must also enable the option saying "Allow OEM unlock" or something like that. I didn't enable that option at first and in fastboot it would tell me I was not allowed to unlock the bootloader. So I had to reboot the phone normally, go through all the MIUI setup and finally re-enable USB Debugging and enable "Allow OEM unlock".

You sir are my hero! That was the issue. Many thanks.
One other question, when flashing the rom is it safe to put it on the SD card, or does it need to be on internal?

Good point, although on mine, "Allow OEM Unlocking" was enabled by default. I used the developer ROM. Is it possible that it's not enabled by default on the stable ROM?

Yes, totally safe. That's how I did it and that's also how I flashed multiple other Android devices using TWRP. Never had any issue putting the ROMs on the SD card.

I did use the stable ROM, so that could explain it.
Alright, another problem. TWRP (tried a few versions) is unable to mount and wipe any partitions... any ideas? =P
Edit "Cofface TWRP Fix" as linked in the guide boot loops me

Installing TWRP without unlocked BL

Hey guys, I have a xiaomi redmi note 3 pro kate running global developer version of miui 8.
I applied for permission of bootloader unlocking on the 30th of December. Ive been waiting for over 12 days and I'm still getting the notorious "couldnt verify device" . I have tried every single tips, tricks, methods thats available on numerous forum threads. None of them work. Don't bother suggesting me a "way" to unlock my bl thats "100% guranteed" cuz honestly i've given up hope. I dont want to unlock in the unofficial way either.
I read a thread here that says it's possible to flash twrp, root and flash all kinds of roms without unlocking the bl.
Could you guys maybe guide me through what i need to do to flash twrp and root? what do i need to do?And again, I have a kate.
yeah i want too flash root and stuff's without unlock bootloader, i have SD version of RN3, btw!

Per MI forum: Mi Unlock often fails despite having bootloader unlock permission.

I see tons of people complaining that the Mi Unlock fails at 50%. I had that too, but solved it (somewhat) after downloading and using a newer version of the Mi Unlock (version 2.3).
Although I get past the 50% mark, the Mi Unlock program fails after verifying phone. [I tried to put a picture of the result below but XDA bars me from this practice until after I have submitted 10 posts.] Since XDA bans me from posting a picture of the result, I will try to verbally illustrate:
The Mi Unlock process runs the entire course - 100% - and then gives me green check mark and says, "Verified". The next step the Mi Unlock program takes is to unlock the bootloader. However it is at this step the process fails. Instead of unlocking, I get a message saying "Couldn't Unlock." Under those words is the following message, "After 72 hours of trying to unlock this device".
Anyone even know what that is supposed to mean? Is that just chinglish? Or better still, how can I get my device unlocked?
I SEE TONS OF PEOPLE WITH THIS SAME PROBLEM! Anyone have any idea what is going wrong? How do I deal with it? Am I to assume the message is suggesting we wait that particular number of hours before we can make the thing unlock the bootloader? Anyone? This IS a question that plagues many in the MIUI forum! And after going back roughly 70 pages into the forum, I see no solution; no answers! Just the same complaint over and over again and again.
I tried the unlocker a few times afterward, over the course of the day, with the same result. However curiously, there is one change to the message. It now says, "After 63 hours of trying to unlock this device". Is this suggesting I have to wait and try it in 63 hours?
Again, I see this same complaint time and time again on the MIUI forum for this phone. Anyone have any idea how to handle this dilemma?
One last question: How do I change out my MIUI ROM (currently MIUI 8.6.8.18 Beta) to a developer ROM? Ultimately I want to install a custom RR Rom or some other custom ROM. But MIUI 8.6.8.18 is android 5.0 LL; and the new Custom ROMs available are using android 7.0. My understanding is I need at least an MIUI Dev Rom with android 6.0 MM on the phone before it will let me leap over to some other Custom ROM with android 7.0. [I tried it. And though everything worked perfectly, (got my device rooted, and installed ZCX TWRP, etc.), it just bootlooped after flashing in TWRP. I tried it with several Custom ROMs - Always with the same bootloop. After exhaustive reading in web forums, the suggestion out there seems to be that I have to go back and install a DEV Rom with android 6.0 MM; then free the bootloader again, reinstall SuperSU (or similar), and then TWRP, etc. , and finally I will be able to Flash to one of the new Custom Rom's that uses Android 7.0.]
With this objective in mind, I downloaded the Dev Rom to my phone (7.7.20 - which is the latest for this phone). However, the UPDATER app on the phone won't update from the MIUI 8.6.8.18 Beta to the MIUI 7.7.20 Global Dev Rom. I select it in the updater by browsing over to it, then click "OK", but nothing happens. Instead of installing the MIUI 7.7 Dev Rom, the app just says that there are no updates...
Any ideas? Thanks
Unlock fails
Hi,
did you find a solution to your unlock problem. I have exactly the same problem and found only lots of solution for other problem with unlock.
Oliver
Now the process of unlocking bootloader is quick.
I deleted my MI account & created a new one. So, applied for permissions again & unlocked in 5 mins after approval.

Please can you provide the exact steps you have taken?
IMHO this would help users like me who did follow the instructions to unlock the bootloader and run into this problem.
I did run into the problem, "After 72 hours of trying to unlock this device", even that I followed the instructions:
Create a Mi acoount (with my phone nr.)
Apply for unlocking, with giving reason
wait for confirmation sms
download unlocking tool
on the phone: activate dev options, switch on usb debugging, OEM unlocking and bind phone to Mi account in "Mi Unlock Status"
reboot phone in fastboot mode
run Mi Unlock prog on PC and log in
when prompted connect phone
The Mi unlocking tool stopped after verifying (green hock) at "Unlocking" with a red cross and show then "After 72 hours of trying to unlock this device".
I do not see where I went wrong...
IMHO this is a f***ed up process of unlocking the bootloader and Xiaomi should work on this.
I haven't read the post, but you don't need to unlock bootloader to root or flash custom roms

Hi,
As far as I know unfortunately if you want to install a custom rom you need to replace the Xiaomi recovery with a custom one, like twrp. In order to do that you need to unlock the bootloader first. Then you can flash the custom recovery with the command "fastboot flash recovery twrp-x.x.x-x-mido.img" for the Redmi Note 4 SD for example.

how? Any link to steps? I have currently resurrection remix 5.7.4 with OFFICIALLY unlocked bootloader, but it's useless because all new ROMs require new firmware and I don't have anymore access to my Xiaomi account which had granted bootloader permission, would like to move from marshmallow to Oreo, but that would require flashing me MIUI, relock bootloader and I will get stuck there and don't wanna apply anymore for official unlock, it's PITA

bootloader unlocked again

Hi
I unlock my note 3 bootloader by officially few days back and flashed twrp to install custom rom. Today I try to install miui 9 in same method I used to install custom rom but my phone is dead now and the bootloader is unlocked again. So i went to unlock tool and try to unlock it again but it shows I can't unlock it before 30 days. Now what should I do how will I fix this. This is my only phone ? please help me
Flash a fastboot rom in EDL mode to restore it to working order.
Once the rom is installed properly and you have the same account details as before on the device, you should be able to unlock the same device without waiting 30 days.
The update to MIUI 9 probably locked the bootloader again.
ok, let me make 1 person very happy before new years. this dude looks like he needs a quick fix before new years. here it is.

I cannot unlock my Redmi Note 3 Pro Bootloader

I cannot unlock my bootloader for some reason now. I had applied for permission around a year and a half back, I got the permissions, unlocked the bootloader and flashed a lot of ROMS. When I flashed MIUI through fastboot, the bootloader got locked again. Now I want to try some ROMS, but I cannot unlock the bootloader. It goes all the way till 99 percentage and it then gives the message 'Current Account cannot unlock this device'. I have permissions and everything because when I go to the mi unlock site I'm directed to the download page, not to the application page. Also, when I try to bind the account to my phone in Mi Unlock status in developer options, it keeps saying 'Couldnt Verify, wait a minute or two and try again'. I've waited for a day and it still doesn't work. I only have one sim card in my phone(the one which I used to get permission) but still it keeps saying the same message again and again.
Please help!
Regards.
Hello. Though I never had the problem (was on NOS rom before I messed something and had to flash miui rom via fastboot and relocked bl, I easily reunlock again using official method like the first time).
Before unlocking, make sure your phone are locked by using cmd "fastboot oem device info" or something like that I forgot. And your phone developer option have allow oem unlocking ticked on. Make sure your phone mi account logged in and of course matched with the one on your pc/laptop. Have good usb cable, drivers, and stable internet. Also you can try unlocking using another version of miui rom (the one you used for the first unlocking).
Don't know if those helps though.
I had the same problem for almost 2 months, asked on the miui forum and nobody helped so i just unlocked it unofficially, works great! On RR N now!
Same
I have the same problem, and also I know a lot of people with it. It seems that xiaomi has banned the unlock tool I don't know why...

Yeah its not an issue with all devices, I do have colleagues who have managed to unlock it officially, but still its a problem for a lot of people.
I have the exact same problem. Stuck at 99 when trying to re unlock, on both miui 8 and 9. I didnt bother trying to unlock with developer roms, just used the method to flash twrp without bl unlock. All good now on nos 8.
I'm happy with flash twrp only without unlocking bootloader since I got root access anyway
Why are you people trying to unlock bootloader when it's not even necessary on our phone? Just look on the forums a little bit more and you won't struggle anymore trying to unlock.
