Question How to relock Bootloader properly? - OnePlus Nord CE 5G

Hi!
I have a OnePlus Nord CE 5G smartphone. A few days ago, I thought of rooting my device and install TWRP custom Recovery. After I rooted it, my phone couldn't update.
So I decided to remove TWRP, Root and Relock bootloader. But after I relocked, and it restarted, it wont boot and showed "Your Device is Corrupt and will not boot".
Then I somehow unlocked it again, unbricked and got my phone back.
So please, send me a solution to relock bootloader properly.
Thanks!

Relock bootloader after flash Global Rom

I bought a Xiaomi mi 8 in a Xiaomi Shop in Shanghai. If I try to relock the bootloader I always get stuck booting on the recovery mode. Besides, I can not flash anything (supersu, xposed...) because I always end in bootloop; in both cases it is a softbrick
Can anybody help me?
If you have a mi8 Chinese box you aren't allowed to flash global ROM and lock bootloader.
And is there any way to fix it? Writing to Xiaomi, waiting X time...?
Thanks for your reply!
There are literally, more than a few hundred threads about not relocking. You modified your phone without reading up, no sympathy here. Your phone is dead if it is not global version. Gone. Paperweight. All the best to you

Hey! Nice to meet you and thanks for your kind answer. This placer is better thanks to people like you.
By the way,my mobile works perfectly. I relocked the bootloader more than once and I just needed to unblocked to solve it. About reading the posts, If you had read you would have realized that what interests me is simply to know if I can re-block the bootloader.
Who taught you to help people in forums that have problems and is probably having a bad time? Hitler?

You can check out official xiaomi forum to see a way. However the official way posted there including open up the device & tinkering with the EDL mode, which is really too much of a hassle :/

Are you having a modern Xiaomi device? How can you relock bootloader without sending it to bootloop?

Better now, at least you're helping to find the information. And you are right, I should read more before doing anything; in fact, I read a lot but you know, internet is so big and it's no difficult to get lost in that information sea (even more if you're a noob in the area). I'll do it better next time.
Have a good day.

I bought it a couple of weeks ago. And no, I cannot relock it without sending it to bootloop.
The thing went like that: I unlocked the bootloader, I flashed the global ROM, I relocked the bootloader and I fell into recovery bootloop. So I entered on fastboot mode, I unblocked the bootloader again (with the Xiaomi tool), I went to fastboot again and I reflashed the global ROM.
The bootloader have to be open to allow the global ROM work. I don't know why I have avoided the brick, but this is what I've done at least twice.

Well if it bootloops the first time after you relocked it, it'll bootloop again & again. Was there any time after relocking did your phone boot properly? If not, you didn't avoid anything. As far as I understand, boot loop = soft brick.
And this is what I found on MIUI official forum:

If I read it right, your device goes into bootloop when installing a Global ROM version and trying to block the bootloader. Probably your device is a Chinese version, which should only have the bootloader locked running a China ROM.
Otherwise, it will be bootloop.

True that. Any Chinese devices running global will get (soft)bricked
Yeah, I was asking is you know the way to lock a chinese phone in global rom. Maybe in the future or with MIUI 10
Is it possible to enter EDL mode via opening your device and connecting the dots to enter 9008 Mode and than use QFIL (Qualcomm_Flash_Image_Loader) to restore the software, instead of going with the MiFlashTool and a needed EDL authorized account?

This is still too early to know, because development is still slow.

Actually these are excellent news, I had never read about a case like this. We knew that if the bootloader was unlocked by the seller and you locked it flashing a global rom (being a Chinese phone) you would get a brick only repairable through testpoint and using an authorized account. But I had never read about doing the same whith the bootloader unlocked by the user and I didn't know if it would be possible to unlock it again. So now we know this :
- Chinese unlocked by the seller -> brick locking while flashing global -> impossible to unlock and edl needed
- Chinese unlocked by the owner -> brick locking while flashing global -> ability to re-unlock and flash normally
I had some questions now :
1.- Did you have to wait to unlock the bootloader the first time? (360hrs, 720hrs.. You know)
2.- Did you have to wait when unlocking after the brick or was it instantly unlocked?
Thanks in advance!

It seems to me that this is not so, as some members still manage. However, since they did not add their personal Account to the developer options, they were not able to unlock the device again because they did not have the account associated with the device. It seems to be something related to different cases.
What can be recommended is that the devices unlocked by the seller, return to Chinese ROM more stable, and have your bootloader blocked. By then, the user requests to unblock the bootloader regardless of the time they have to wait. Thus making everything safer, in the case of possible bricks in the future.

Have you ever heard of read about somebody doing that? Because I think there's still the doubt about the unlocking method used by the sellers, whether they do a regular unlock with an account or they patch the boot in any way which could cause problems locking the bootloader.

[Q & A] help Xiaomi Mi 8 won't boot

Firstly I want to thank every one here
I want to clarify for the first that the phone was already unlocked when I bought it. All go well until the day of doing this stupidity
I put the version 8.9.20 it got stuck (this miui version can't be installed on this device __1st attachment) but when I wanted to return to 10.0.20 with fastboot it tells me locked phone I managed to update to 8.10.25 with another tool but I was still stuck with this screen (1st attachment)
So I thought I need to unlock it I launch the unlocking tool he announces this message (current account is not bound to this device __2nd attachment)
Conclusion phone that has not done yet a month with totally unusable I was so happy with this phone that I could not return to iPhone.
Please find me a solution dear friends
My mi account id is 144253908
My Device is Xiaomi Mi 8 Global version bought from Gearbest
Do you have an unlocked bootloader? Flashing different rom, like you had installed on your phone (global, xiaomi.eu) need unlocked bootloader and twrp recovery. Or, if you had opened bootloader, and you flashed with Mitool, then you should unmark befor flashing the flash and lock option, cos ist closing your bootloader and bricking your device. Also have the last time xiaomi devices antirollback. For more info have a look in forum!Its already thread about this!

Realme In-Depth test

Hello Everyone,
I have been using Oneplus phones from a long time and I found it pretty straight forward to just do "fastboot oem unlock" and you are good to go.
Now from what I understand, in case of realme, you have to sideload an realme provided apk and request for In-Depth test which if approved, you'll be allowed unlock your bootloader. I think they (realme) are pushing our serial number and carrier info to their servers to see if you should be allowed to unlock bootloader.
I do not plan to unlock my bootloader right now but I am concerned if realme's servers went down in future or if they stopped providing support for our device in coming year, how would I unlock my device ?
Can I initiate In-Depth test now and actually unlock bootloader later ?
i did it, you never know it might vanish and if you procrastinate, and option vanishes you will kick yourself research for yourself but this thread claims you can re-lock so read it CAREFULLY https://forum.xda-developers.com/realme-x2-pro/how-to/guide-unlocking-bootloader-to-getting-t4010189
fears kill dreams!
who knows what happend to realme or oppo in future or their servers!
X2PRO is 4g device, maximum we may use for next 24-36 months before going to 5g or different device!
i immediately unlock the bootloader, (got approval in 5 mins)
yes you can relock but i don't plan to, (but thats me)
moreover same goes xiaomi, sony also! (the server thing) they monitor what devices are getting unlocked!
Thanks for your replies guys. I understand that I should unlock while I can.
Point is I don't want to do it right now because I am somewhat satisfied with what RUI has to offer. Plus I don't want that safety net headache right now.
I want the option to unlock later lets say when Realme X2 Pro's update support ends and I want to flash Android 12 (when it comes)
My question is, if I get approval and not unlock it, will this approval be retained even after updates and system wipes ? So that I can unlock it later without approval

You can just unlock the bootloader and keep everything stock unrooted. That's what I first did back when I got the phone. There's no harm, other than losing widevine L1, I think.
Got it, thanks.
My original question remains unanswered though.
I'm decompiling realme's in-depth apk to understand what it does when you are approved for bootloader unlock. Will update here if I find anything interesting
if you want to go to android 12 later just follow that thread i showed and relock it and go stock and update

Hello everyone 👋

I have come across many forums in the past but finally decided to create an account and be part of this community. I had a Huawei p8 lite 2017 and now own an Oppo A91, both phones are anti-modding so to speak. The Huawei had the bootloader locked and to unlock it I needed a code to get from a site that I had to enter via fastboot. The Oppo on the other hand has just the fastboot mode locked. But I'm not one to stop right away and I found out on XDA about a tool called MTKClient that allowed me to unlock this phone and so after a while I decided to bring a TWRP for this phone since there are a lot of fake and generic guides online where none give you a working recovery.
