Accidentally Locked the bootloader with the custom rom installed

So I installed a custom rom in my new k20 pro lately, and accidentally locked the device after installed the custom rom inside. Now, my device is refusing to open the new rom and stuck in redmi recovery mode. It said that "this MIUI version cant be installed on this device". I tried to unlock the phone again, but xiaomi said that it takes at least 30 days to unlock a new device. Im kinda sad and confused about this, please help.

How did you lock the bootloader with custom ROM installed?

Did you try to flash custom rom using miflash?

Hi! I have the same issue on my Xiaomi Mi 11 Pro (It was Chinese) but it came unlocked with xiaomi.eu rom.
After i installed a global rom, and google wallet nfc pay did not work, so i thought okay i will lock it then so maybe wallet would accept it, (with the eu rom it worked before) so i put the device in fastboot and used fastboot oem lock on cmd...
And from then it stucks on miui recovery 5.0 screen, and says, this miui version can't be installed on this device...
I might not enabled oem unlocking before i shut if off, but i added it to my mi account so i dont know if after a week i can maybe unlock it. But i think the other possible solution would be to sideload the original chinese stock rom, which is for M2102K1AC, Mi 11 pro, codename mars, but i couldn't find it anywhere... If someone can upload a link to it, that would be a huge help! Or any idea! thx!

HI! i got a mi 11 pro 1 year ago, and it was offically chinese, but it came unlocked with Xiaomi.eu firmware, but i could't update it via the updater app, so i searched and found the global star version and just flashed it, everything worked, only now google pay nfc didnt work, it said that its probably because of the unlocked bootloader, so i got to fastboot and in cmd i sent fastboot oem lock, and since then my phone is stuck in miui recovery 5.0 screen and says that i cannot run this firmware on the device, i tried to unlock it but failed, maybe after a week, but i think that i didnt turn on oem unlocking on the phone itself before this... So im just hoping that after a week unlocking could be done... Or my other idea is, that i could install the original chinese rom with sideload, because i managed to install another global version on it since, but the result is still the same, the only problem is that i cannot find literally anywhere a mars codenamed firmware...

Anyone who might have the same situation, i found a simple, but effective solution, not sure if it works on every xiaomi device, but i will write down the steps here:
You need to use XiaomiADB, here is the download link and the description for how to use it -> https://xiaomiui.net/how-to-use-xiaomiadb-8044/ (if the page is not available, then feel free to msg me!)
For xiaomi adb, you need to go to 3rd option on the miui recovery screen, NOT THE FASTBOOT
So basically i went through the steps to “xiaomiadb sideload_miui <filename>”
And I tried to install a rom, BUT IT DIDNT ACCEPT IT!
The message was:
ERROR: This rom cannot be installed, server code -> 2001, server message -> Can't install unofficial rom
after trying 4 times all the same and: Installation of this rom via stock recovery is not allowed by Xiaomi
Says Installation failed, and then i just decided to download another rom so i PLUGGED OUT THE PHONE right after this, and went to another room to connect to wired network, to download and try a different rom... when i came back, to all my surprise, the phone was turned on, so i went to the setting dev ops and enabled bootloader unlocking, linked it to my account enabled adb and everything that is needed to flash another rom later, so then i rebooted and again, miui recovery 5.0 screen, but now i enabled unlocking, so i put the phone in fastboot, and tried MI UNLOCKER TOOL again, now it says: Please unlock 168 hours later. And do not add your account in MIUI again, otherwise you will wait from scratch.
So that means, after 7 days i wll be able to unlock it, until then, i can turn it on with the above method, in short try to sideload (copy and install) a rom to it, and then after it failed, plug it out and just wait like 10-20 maybe 30 seconds and bam your device is normally booted... I hope it helps to some of you, (i have been searching for the solution for almost a week, my other option was to pay someone who can MAYBE do it or send the phone back to china and pay the repairs, so im really happy with this method! If it helps to you, please reply so i and the others will know that it worked! Have a nice day!

Question Camera won't focus

Hey everyone. I'm hoping you can help me out
I have a mi 11 running 12.5
The main camera will not focus on it.
I had this problem before, and doing a reset fixed it, but now it is permanently not focusing.
I don't know if I'm SOL or if there is something that can be done
Even if I try manual focusing it doesn't do anything

Try to download" MIUI hidden settings" in AppStore
With that u can calibrate ur camera

On mine calibration always failed

Try to wipe the cache of the camera app

If you can, just try other rom like MIUI dev version or MIUI eu.
Or just flash latest MIUI rom again via fastboot and pray for good luck.

I want to install MIUI EU rom but I can't seem to get MIUI Unlock to ever recognize my phone being connected to try to unlock it.
This is like the 8th Mi phone I've had since the Mi 8 and I've never had this problem

Try using the original cable that came with the Mi 11 and avoid plugging it into usb hubs

I remember i had once this issue with my pixel 3. i just dropped my phone on a book for not damaged it, it was my lens that was blocked.

Now to wait 3 more days before I can unlock
I can't seem to find a stock 12.5 chinese rom on the MIUI site to try flashing through Fastboot

Not needed. I came from Global and a friend from EEA ROM and both work fine. Just don't re-do the procedure again before the timer runs out, otherwise you need to wait again.
Just wait for the timer to run out, unlock your phone and use the latest fastboot-ROM from Xiaomi.eu

Welp... finally got the bootloader unlocked, flashed back to 12.0 instead of 12.5 and it's still borked
Guess it's time to throw this on eBay and see what I can get with a wonky camera

Question Freezes and Restarts

Hi Guys,
i am experiencing random freezes and weird restarts for about 4 weeks now. Sometimes the MI Logo shows not in the middle but on random locations on the screen and it is not necessary to do the pin input. Did anyone have the same experience? This is the Reason to try and unlock the bootloader.
Greetings

And you have?
Rooted?

Bone stock?
Magisk?
Aosp?
Xiaomi eu? Beta? Stable?
While its not nice that you have experienced some issues the technology is no there yet...we cant read minds or/and predict outcome
Please provide us with something we can work on and i am sure we will do our best.... But standard advice would be factory reset as nr1.
Take care and best of luck

I have almost the same symptoms with Mi11 global version Miui 12.5 locked bootloader , the phone freezes and the screen flickers, but no problem appears on the bootloader or the recovery, the strangest thing is that when I use the PUBG mobile games everything works normal, I tried several ROMs but the problem persists

Too bad. Sometimes adb also gives error that partition a does not have enough size

adb???? flash using miflash. or another tool. this error mean u have damaged partions table. if you follow the guides u dont recive any error. works fine for miui 12.5.2 and any other version. but i think u didnt follow the guides with attention.

My phone is the Chinese version（Redmi Note 10 5G and Redmi Note 11 SE
）, but miui global version also brushed, some of the old firmware can be brushed, you can enter the desktop, but part of the existence of 4G5G signal is weak, or even no signal, some have a signal but no sound to call. So brush the correct miui firmware is important
His problem is mainly manifested in the GSI problem.

Redmi Note 9 - How do I restore my IMEI? I don't have a backup of my nvram/nvdata but I have the numbers.

How do I write IMEI along with baseband version back to my phone? I really don't want to risk bricking it again, that's enough stress for me in the past two days
I heard that I can only flash IMEI 2 back to it, and if I want flashing IMEI 1 as well I'd need to install a custom rom on the phone. So if that's a solution I'd love if someone could help me with it. MIUI 13 is slow and laggy af (which is the reason I bricked the phone in the first place, to install a better ROM).
But here's something, when I flash the phone's firmware through fastboot, issues start to rise (as per my experience with it so far), but through SP Flash Tool, it's alright. So I'd love to know if installing custom ROMs using the tool would be alright, if not then if recovery is required or if fastboot is fit for the job. If that's an issue I'd love if someone could give me advice when it comes to it.
Old post 1: (not my current situation)
"Long story short, I bricked the phone and after months, I've finally been able to repair it (downgraded from MIUI 13 to MIUI 11), but I lost my IMEI. I have the phone's two IMEI numbers, but I could not find any tool to help me write it to the phone. Either that, or I don't know whether the phone should be turned on or off, or if there's any special mode that's required for that matter.
Help would really be appreciated."
Old post 2:
"It happened after manually installing engineering ROM on it, now I can only doubt it's BROM mode that's working and nothing else, but I'm not sure. SP Flash Tool doesn't want to work with the phone since I want to flash the stock rom back. I really need help please."

The reason why my phone broke in the first place was due to flashing a misc.bin file after following a YouTube tutorial. It was part of a process to download twrp on the phone unofficially. Since then I started looking for ways to fix it until I finally found a post that had to do with fixing nvdata corruption (which was the error I had prior to fixing the phone) which helped.
So yeah, I don't think I can trust flashing ROMs on my phone as much as before, but I'll still try the engineering ROM thing.

Yep, it doesn't show up as it's name or "Android", it shows up as MediaTek USB Port (COM3), that's why I doubted it to be in BROM mode.

I always recommend a NV Backup before messing up with your own device, that's all I know.
Download the file attached here but remember you can fix only second IMEI using this method. Please don't try to fix both IMEI or NV Data will be corrupted again.

The guy in the video is using MIUI 12, I have MIUI 13. I don't know if that's an issue but someone in the comments said something about MIUI or so. I'm not a professional but many times when I see tutorials they're very specific with the MIUI version.
Also, I'm not sure how to back up nv data, do I use mtkclient or is it somewhere in the attachment you sent me?
And one more thing, my phone's baseband version is unknown, could that affect the process?

The phone keeps rebooting when connecting it to Maui META. Like it shows META MODE at the bottom of the screen but then it turns off. Now it's bootlooping. I guess I'll have to flash MIUI on it again. At least I still have access to fastboot and recovery.
Update: NV Data corrupted after flashing MIUI, but I got a solution that hopefully works.
Update 2: After flashing MIUI 11 (along with some other nvdata and nvram files, i think they're just empty), it works now and the error is gone. But as I said IMEI issue's still there. Maybe I would need engineering ROM for this one? Although it bricked my phone before.
Also, the phone started bootlooping before attempting the Maui META thing, so maybe it's either the manual formatting of partitions or the files I flashed on it.
