Really need some help - Xiaomi Mi 4C

I have applied to be able to unlock my boot loader time and time again, and i don't think its gonna happen.
Is anyone kind enough to let me use their Mi account if their Mi account can unlock phones bootloaders? I wont take your account or anything. Just need to use it to unlock my bootloader

You can unlock your bootloader without getting official permission.
Sorry I'm too lazy to find out the exact tutorial, but as far as I remember it works like this: Use Mi software on PC to flash an old version of MiUI ROM (that was published before bootloader was locked), then you can flash custom recovery and do whatever you want with it.

It's this: http://forum.xda-developers.com/mi-4c/general/guide-unlocking-mi4c-bl-verification-t3336779

Device bootloader locked but can't boot

I have a chinese Device, loaded with a global rom.
I decided to "fastboot oem lock" the phone, now it won't boot anymore, saying that I can't use the current MIUI version.
I tried unlocking it again, but I have no linked account, and I can't find a way to flash the Chinese ROM as I always get an error, probably due to locked bootloader.
What can I do?
Unlock your device and usei tool with fastboot rom.
I cannot unlock it, it asks me to use an user associated with the device, but I never associated one and now I can't do it.
Your best bet might be to contact Xiaomi directly. BTW, what where you doing since it's unlocked but won't boot?

[Help] I bricked my device

So, I ****ed up.
TL;DR: My device is locked with no way to unlock it.
Got it today, wanted to flash a ROM. So I install TWRP, all fine. I reset everything, also format, then of course my zip on internal storage is gone too. So I put it on a SD card and reboot the phone to recovery again. But I can't, because after wiping it just shows "system destroyed" or something. So I panic. Then I realize I can flash stock ROM via MI flash tool, do that, install TWRP again. But I still can't flash because the version is too low. So I decide to flash stock again, do an update and try again. But this time I forgot to turn off "clean and lock" in the MI flash tool. So now the bootloader is locked and no stock ROM is installed. So I try to use the MI unlock flash tool, add phone to account, but no, because I didn't sign it at first it won't let me unlock because "your account isn't associated with this device". And now I can't do anything.
Is there anything I can do now apart from this testpoint method? I don't really wanna take the back off, I'm afraid of breaking it. Also the next Xiami store is like 800km from me and I don't wanna send it back cause it already took 2 months here and I paid 60 euros to customs.
I would really appreciate any help you could offer me. Thanks in advance!

1. did u officially unlock bootloader?
2. can u access fastboot?
3. did u remove mi account after unlocking bootloader?
4. But this time I forgot to turn off "clean and lock" in the MI flash tool. So now the bootloader is locked and no stock ROM is installed
did you complete the flash process in MiFlash-Tool? or while flashing u plugged out usb?
If you have selected clean all & lock then your phone have booted to os, i think you locked the bootloader before flashing because bootloader lock command runs after firmware installation is complete

1. The bootloader was already unlocked as I got it.
2. I can boot into fastboot mode
3. I skipped adding it in the first place cause I never really wanted to use the stock software, it's too china for me
4. I flashed after wiping in TWRP, it "completed", as it didn't show completion but the phone rebooted to stock recovery and stayed there, displaying "this MIUI version can't be installed" or something like that.

That may be true, but maybe that's cause it didn't succeed in installing MIUI this time, see other comment to where it is now

since your phone is not associated with a mi account, u might need customer care support.
u said bootloader was already unlocked.
if u bought a used phone ask the original user for mi id+pass to unlock bootloader again

Ok since you have reached point where only a service centre visit can unlock it, I suggest you use an authorised account! I believe there are people online who accept payment in return for unlocking the bootloader (I have no idea how to find them tho, sorry)
These accounts are rare and are used by service centres to unlock bootloaders and stuff..and which TWRP did you even use? Use Peter's, the official one is **** and doesn't support decryption.

U should buy a deep flash cable or u may make it at home.(search on youtube). Clean flash stock fastboot rom from mi flash in edl (emergency download mode). It will flash successfully. Then set up a mi account ( may be cratate a new one to unlock the bl). Then give try to mi unlock tool.
Note - suggest to buy a deep flash cabel instead for home made.
U may done flashing in edl mode only because bl is locked now.
A year ago i also forget to deselect clean and lock option and locked my bl accidently but i used above method and get success.

Actually while flashing it locks the bootloader after complete installation is done, so might be you first locked the bootloader you can check the script in fastboot rom

So I tried this, and it did not work either with edl mode, it is still asking me for my account, which isn't affiliated with that device.

I try to flash it buy theree method already, EDL is unsuccessful it need an authorize account; Miflash Tool Pro, flash recovery rom it shows " Couldn't verify, looks like current ROM's network carrier type is different from that in the Recovery package..."
V10.3.8.0 and 10.3.10.0 got the same result; the third try is actually the XiaoMi adb method, someone is success to save their redmi note 5 by that...but as i try it on N7 pro it fail...!
Just wonder this N7 pro is brick by ARB already? any suggestion at all guys?

Have you tried to unlock using mi unlock?
If the devices was unlocked officially, you should be able to unlock again immediately without asking for the permission.

how we can unlock phone without test point?
Does anyone know how to solve this problem?
Hello. first of all you have to remove the back to be able to put the phone in edl mode. then you need to find someone with an account authorized to install a rom stock china for which you will have to pay. I paid $ 15. then you will need to associate the phone with your me account and unlock the bootloader. nothing else works. for a month I lost my nights trying dozens. until I paid everything was in vain. or you have the option of an authorized service, but I am convinced that it will cost you more. success.

If you're able to access to EDL mode, you should be able to flash using QFIL tools instead of MiFlash. Something like this

[PayPal Reward] GM1915 Converted International; Root/TWRP Questions [SOLVED]

I posted a thread on this, commented on a couple other threads, posted on Reddit, and I simply cannot get straight answers across the board. All the feedback I'm getting is different. I am willing to PayPal friends and family $5 to the first person that can answer my questions with links to sources just so I can ensure the information I'm getting is correct. I haven't rooted a phone since my 1st Gen Moto X so I'm out of the loop, but have a understanding of everything.
I have a GM1915 OnePlus 7 Pro that is T-Mobile SIM unlocked. I followed the tutorials HERE and HERE to flash the global firmware and all went well. Only issue I had was my SIM was being detected but no service, so I did an OTA update to 10.0.3 and my service is working fine now. Here are where my questions begin:
1. Now that I have installed the international firmware I don't need to get a bootloader unlock from T-Mobile/OnePlus, correct? I can just use the OEM unlock option and unlock via fastboot?
I have had people tell me I am good to enable OEM unlocking and use fastboot oem unlock, others have told me I still need to request a unlock, others tell me to downgrade to SP3. I just need a straightforward answer: Can I use OEM unlocking or do I need to request an unlock from OnePlus?
2. I know bootloader/root can sometimes cause certain applications to not function, but I've also read Magisk has a setting to correct this. I'm mainly just concerned with Google Pay, is there a method for it to still function with root?
Again, I've had some people tell me I can't use Google Pay, Netflix, or anything like that at all, others tell me Magisk Hide and SafetyNet will fix this issue. I also had an individual state "However, recent changes coming might thwart this.". Again, can I use Google Pay or can't I?
3. Part of me would actually like to use the phone stock for a week or so to see if I even feel like I need root access. I am currently on OS 10.0.3, if I update to the newest OS (looks like 10.3.1 is the newest) will I still be able to root with Magisk and flash TWRP? I would assume yes since you can do an OTA update and keep Magisk, but I just wanted to verify.
So if I update to 10.3.1 can I still follow the same tutorial listed under question 1 and it will work? Doesn't the most recent version of TWRP/Magisk support 10.3.1? Or will I need to use MSM and go back to 9.5.X (can't remember the exact version, but it's the OS it puts you on when you follow the steps for international firmware flashing)? Can I even go back to 9.5.X after updating to 10.3.1? I see release notes for TWRP that state is now have Android Q support but I just want to ensure it's compatibile with 10.3.1 or whatever the newest OS is.

I know regardless my phone is going to get wiped, I just want to be prepared on what I need to do if I decide to root.
I don't need links to tutorials, there are plenty of them and I understand how flashing TWRP and Magisk works, I just need my above questions answered with sources. I have searched around for a couple days and cannot get straight forward answers for any of these. First to answer every question with sources I'll send $5 PayPal.

Firstly I can't give you a reputable source, and I don't want any money. I actually recently bought a Renewed Oneplus 7 Pro from amazon when it was 420, its the Black 8GB 256GB T-Mobile GM1915 model. So here is what I found out , and currently running Ill post some pics to show you
1. If you followed the guides above exactly and everything went smoothly your pefectly fine to use OEM Unlock, it basically installs a version of the firmware that doesn't check for a boot loader unlock token. I had originally requested one as well than found this nifty guide and it worked amazingly.
2. Yes it will work perfectly fine with Magisk, just use the Hide Magisk , it will resintall under a new name. Than you can even go further and use magisk hide to hide it from each app independently. As for google pay I have mine setup and it worked fine. I haven't actually been able to go into store and use it as we are very closed off in home now, but It allowed me to add my card fine, verify with my bank and all that good stuff. As for netflix yes it will work but since you unlocked bootloader you lose the Widevine DRM L1 certification and thus can't watch in HDR anymore. It still works fine though and honestly looks alright to me.
3. I had updated my T-Mobile OS all the way to latest version forget what it was at the moment, and than I did the tutorial to unlock the bootloader and flash twrp/magisk/rom. It worked out perfectly fine so you should be fine as well. What I would do is use the tutorial above unlock bootloader, because that version of the OS doesn't check for unlock token, than flash a stock Global rom 10.3.2 is avaliable now. and enjoy it for awhile and when your ready install a custom rom and magisk.
I'll add some pictures of things you asked about. Sadly I can't show my model number in system due to rom but i showed it connected to my pc.

When you say this, did you update your firmware OTA on the T-Mobile firmware, or the Global/International firmware using OTA? I don't want to skip any incremental updates and cause issues so I might update using OTA to the newest it provides than use Oxygen Updater to get to 10.3.2. As long as I can be on the newest firmware and still unlock my bootloader and flash TWRP I'm fine. I mainly got this phone because it ticks every feature box I want and it can be rooted, but I'm up for using it stock for a while to see if I even want root.
Edit: I reread you post and think I looked over something about unlocking the bootloader. So the specific version of the firmware you flash to to swap to the international firmware doesn't require an unlock token, so if I wanted to use the OEM unlock I'd need to be back on that version, but if I wanted to unlock after I update to 10.3.2 I'd need to request a token. Am I understanding that correctly?

It was the T-Mobile firmware. 10.0.3 version. I had done it before I was even thinking about unlocking bootloader and flashing. Than when I saw the custom ROMS + Kernels where you can gain massive performance gains or optimize battery like mad I was sold on it. Plus the ugly t-mobile boot screens annoyed me. It is an amazing phone and prices can be had at its a steal. Also their is a TWRP that lets you dual boot and use shared data partition. So you could have one boot as a custom ROM, and another as stock and have the data shared in a common partition. Get a little of both ^_^
Like I have two profiles and one is more performance / battery Optimized
This other was more for fun on seeing how far I can push scores I am bored during this lockdown lol

You know I am honestly not sure on this part, I did the bootloader unlock right after I followed that tutorial with the MSM tool. I am pretty sure its just the t-mobile firmware that blocks you from doing OEM unlock with out token. Not the global. But one way to find out be enable OEM unlock in developer settings, and run the fastboot oem unlock cmd. See if it works. If not you have your answere and will have to go back to other version. If you want you can always relock bootloader. I would test this but as I've already unlocked , re-locking and unlocking probably not give proper answer. But if you want I can install 10.3.3 lock bootloader and try to unlock it again lol.
EDIT: a test in sues.

You know I am honestly not sure on this part, I did the bootloader unlock right after I followed that tutorial with the MSM tool. I am pretty sure its just the t-mobile firmware that blocks you from doing OEM unlock with out token. Not the global.

So I tried fastboot oem unlock after updating to 10.3.1 and it asked me if I wanted to unlock without prompting for an unlock token. I didn't choose the option to unlock, I kept it locked, but I think if I can get that far I should be able to unlock without a token on 10.3.1

I can confirm now officially. After locking my bootloader, using MSM tool to go back to T-Mobile updating to 10.0.3 and trying to unlock bootloader it wouldn't work as I thought.
When using the MSM tool to go to international version and updating all the way to 10.3.2, it worked perfectly fine. So you can be on global rom and not worry about being able to unlock bootloader later due to updates Very awesome can get on global rom and not compromise bootloader so can have all security in place

You are the GOAT. Not only does this help me but hopefully some other members of the community that wish to update and try stock before unlocking the bootloader.

If you follow the main guide on xda exactly you're going be fine. Once on global your essentially done because than you can flash a twrp through fastboot and install any rom, kernel you want. As well as magisk. The most important part is that msm guide. Now if you want to be more official get an unlock token and do it the regular way through fastboot with the unlock token. It took about a week in a half to get mine. But the msm guide works perfectly. Also I've gotten my device stuck in multiple fastboot loops and stuff their is always a way back.

Once you follow this you will be off TMobile stock and on global stock. Here you can choose to unlock bootloader or not. You don't need to root and install twrp to be on global rom. Just basically do the msm guide than. Update through the oxygen updater app to latest.

strange all you really need do is hook it up to pc, enable usb debugging which u've done. type adb reboot edl, wait for it and have msm open and it should connect. My only thing to suggest would be try another cable or another port on the pc. sometimes i've also noticed fastboot can be odd for me and I have to reboot the computer for it to notice my phone . I'd suggest try those things. Did you check your system model and see if it was the 1915 model with the GM31CB?
dont know if you got it or not but heres link to the commands https://droidfeats.com/unlock-bootloader-oneplus-7-pro-t-mobile/

Bricked Mi Mix3

Hello all, I was stuck in recovery for some time and non of instructions were working for me, so I decide to flash stock rom via Mi Flash Tool.
I downloaded MiFlash20191206 and extract it I downloaded Xiaomi_Mi_Mix_3_V10.2.1.0.PEEMIXM_20190118.0000.00_Global_9.0_XFT ROM and extract it, run Mi Flash, put the phone to fastboot. But when I flashed device I wrongly choose clean_all_lock. So I ended up with a locked bootloader. And when tried to boot MIUI I receive message:
"This MIUI version can't be installed on this device"
So naturally, I tried to unlock bootloader with MiFlash unlock. Downloaded miflash_unlock-en-3.5.1108.44, extract it and run.
Login with my Mi Account and tried to unlock but ended up with the message:
"Please add your account in miui settings -> developer options -> mi unlock status"
Which would be easy to do but as I am not able to boot MIUI I am not able to go to settings.
So did I finally bricked my phone or is there some hope?
I haven't found myself in this predicament (I almost did, but interrupted the flash before it finished to stop the lock). You could try to fastboot the (assuming its a CN device) CN files over the top with it locked. It *should* allow that even if the BL is locked. Then you should be able to boot up, go through the unlock process again. I would see if you can find an older thread where someone did this, or see if you can find one in the Mix2s forums for advice. I know people have had this problem before and been able to fix it.
So in the end I solved it by going to local MiPoint and guys there were able to flash CN rom even with locked bootloader.
I asked them if they have authorized account, but they use some third party software. They did want to tell which, but I get some info that it is paid software and cost around 200 USD and also that they used Miracle xiaomi tool before for this, but now servers are busy and it's not usable anymore.
Any idea what's new software?

Bricked completely, need advice if it is possible to recover.

Hi everyone, to add some background I am fairly familiar with flashing this device as I have had it for 3 years and have done a lot of tinkering with it. However this does not mean I am good, and I have definitely soft bricked this phone a lot over the years, but today I think I finally hard bricked it.
Basically, I was using stock MIUI but with TWRP recovery and wanted to add my card to Google Pay, however it said my device was not secure (or something) so I thought it must be because I don't have fully stock MIUI. So I decided to see some way to return the stock recovery, and after doing 5 minutes of research I saw that I could flash the stock ROM and then through fastboot run "fastboot oem lock" which would reset it to stock. However I definitely did something wrong because after rebooting into recovery it says "The system has been destroyed, Press power button to shutdown", and the phone will not boot normally anymore.
You might now suggest that I should unlock my bootloader again through Mi account, but the problem is that I wasn't logged into my Mi account, so I think this is impossible. I have tried running "fastboot oem unlock", but that obviously returns an error when I tried.
Is there any hope to recover this device or is it gone forever? I would appreciate any advice. If you need more info please just ask.
Thanks!

Do u have stock mi recovery on it?

Thanks for responding, I will try this as soon as I can get a different phone to receive the SMS for the Mi account. As for the recovery, I'm not really sure what exactly it is because as I said, when I try to boot recovery it just says, "The system has been destroyed".
Hi, I've found that tutorial, but for other Redmi model, still maybe helpful:

this is not helpful since u have locked bootloader, video is fake, it is just flashing fastboot rom by cmd nothing else.
Had this same problem a few months ago, just try to unlock the phone again using mi unlock. After unlocking quickly install a custom recovery and you should be good.
Thanks for the suggestions guys, I'm in the process of trying to unlock with mi unlock however it says my account is suspended when I try to log in, I will be trying to recover it but I hope it will not cause any issues with unlocking the phone if I change the phone number as part of the recovery process.
Hello again, it would seem that I will not be able to unlock the Mi account that I used to unlock the device originally so I think I am out of options unfortunately. I will look into buying a new phone.
