SMG955N asks for unlock code after flashing a rom

I bought my Korean s8 plus new and everything worked great at first.
I rooted it, installed twrp and flashed renovate 3.0 on it. This week I decided to update to renovate 5 but after doing a full wipe to get everything working I ran into the issue of my phone asking for a sim unlock code.
I can restore my backup to renovate 3 and all is fine but if I wipe the phone or restore with Odin I get prompted for the unlock code. I'm using the phone on t mobile.
Any ideas on this?

That screen appears when your phone isnt unlocked for use in any other career, that's when you have to enter the unlock code for IMEI, but when shows PUK network lock code is when you entered a wrong imei unlock code many times... First... Put 12345678 or 11111111 to unlock the sim network PUK and it will ask again for the imei unlock code , if you don't have it.. You'll have to pay for it.
When a phone is attached to one specific career, if you put another sim that isn't from the native career.. It won't show anything.. That's when you have to change Rom in order to show that screen asking for the code.. That's how you unlock it.

The Korean smg955n is supposed to be unlocked.
It worked fine at first then all of a sudden started asking for unlock codes as well as the puk code which I got from t mobile.
For a sim unlocked and bootloader unlocked phone this thing is a pain in the butt to flash roms on...lol

I have a similar problem with Korean S8+ that was given to me by my nephews friend who was in OZ studying. There are no issues with sim lock or network lock or anything like that, but I think the reoccurring password request has to be somehow linked to a Korean carrier or previous owner or even possibly the IMEI? I have loaded combo software on it successfully but have tried every trick to get OEM unlock to show up and can’t, therefor I cannot root. I’ve even installed different firmware versions and still the same persistent password request in Korean is the first thing you see when the phone has loaded the new software??
Can anyone please tell me if they have encountered this type of thing before and if there is a way around it. All checks on blacklisting both internationally and local here in Australia comes up clean.
Look forward to some advice.... cheers

Same here

rip dude

Already tried dload method with a point version firmware? It should be your last chance to save the phone

You can also try to restore it with eRecovery. I remember when it happened to me, and it's quite scary when all stuff is locked, but that will do the trick.

I think you did it successfully, since there is no FRP lock on chinese oeminfo.

eRecovery + FF will fix most FRP lock issues. Setup FF proxy server and run eRecovery to download the package = a clean, working phone.

Both are the same procedures. After you're done with the ROM installation, your bootloader will be locked but FRP will be unlocked. Then you can unlock the bootloader again in fastboot (turn on OEM unlocking in settings/developer options).
*** Backup your data before doing this. This basically wipes everything and makes the phone brand new.

Will give this a shot in the morning

Here's what worked for me. Somehow my bootloader was relocked so I unlocked it, set up the device without any Google account and then flashed the TWRP and rooted it.

Relock bootloader

Hi everyone, I am selling my phone and would like to relock the phone and avoid having that message that appears every time I rebooot the phone..
Is it possiile to relock the phone without problems?
Could someone kindly show me how.
Thanks
Cheers

Make sure you flashed a full stock RUU first, just to make sure the software is absolutely original. Then you can do it via fastboot oem lock in download mode.

Hello friends,
I wanted to see if it worked.
I also want relock Bootloader. I have read that it can come to a software brick.
Thanks

what ever you do make sure you put on the original rom on, i made the mistake of doing it when I had a patched boot file and now it wont boot.
I'm not panicing just yet as from reading up I can just flash it using the SD card method. but i got to wait till I get home as i havent got a 16/32GB sd card with me.

Thank you.
just to be sure, this is what I need to do?
1. put an original RUU on your microSD card and rename it 2Q55IMG.zip. Then open the download mode and confirm the flashing.
2. then use "Fastboot OEM Lock" in download mode to lock the bootloader.
Did I understand it correctly?
Thanks

Yes, those instructions are correct.
Although I'm not entirely sure that will remove the message you're looking to remove but I might be wrong. Hopefully I am cause I intend to do the exact same thing as you.
Let me know how it goes

Thank you ,
But would be nice if someone could confirm, who has already done so with success ....

Can confirm this is the way to do it, but make sure you put a stock rom on first as it doesn't like it if your boot is patched.
The message is phone is RELOCKED after its all done

HELP!!!
Hello again,
I have a problem. I have the
2Q55IMG_IMAGINE_UHL_O80_SENSE10GP_HTC_Europe_1.30.401.2_Radio_sdm845-000201b-1807311356_release_528110_signed_2_4.zip
renamed 2Q55IMG.zip on the SD card and flashed. I have UHL (Single SIM) HTC_034.
Then i use "Fastboot OEM Lock" in download mode to lock the bootloader.
I confirm the query with Yes.
After that I have a bootloop, can't get out of it...
What can I do?

Did it boot into the rom before you tried to relock the bootloader. Also I wonder if the rom you used was to early. I used 1.53.401 when I did it. I assume that is the same rom for single / dual sim htc_034 models.
I would be getting a more uptodate rom and reflash again via sd card method

right, just download the 1.21.401.4 and try it...
Edit:
it worked with RUU 1.21401.4. Apparently the RUU 1.30.401.2 is faulty. ;o)

Which CID does it have?
Code:
(bootloader) cid: 0x00xx
use getvar all to find CID
Code:
fastboot getvar all

Just need to update to latest OTA and wait a bit.

Please update the device to the latest version and then initialize it.
You can then proceed with the setup online to activate it and get oem unlock working.

Thanks for asking. You need to have an active mobile data or internet for at least one week for the OEM unlock option become available in the developer settings.

72 hours in many cases, after connection to LTE or WiFi
Edit: Your CID should be good for unlocking, just have to wait.

After initializing the device, connect it to wifi and set it up again.
During the setup process, the device will be activated automatically.
After that, the oem unlock option will be enabled.
No matter how long you wait, the option will not be activated.

What do you mean with "set it up again"? I did a factory reset, but that doesn't help. (I didn't expect it to help, because what happens then is the same as what happens after you unbox it and turn it on.)

After a factory reset, you have to go through the setup to reactivate wifi if you don't have a sim card in it and reenable Dev Options.

I did that. So I still have to wait several days until the OEM unlock option is enabled?

I did update to the latest versiion, although I wonder why that is needed is you are going to do a factory after that.
Before and after the factory reset I hada working wifi connection.
The OEM unlock option is still unavailable. So I think I have to wait a few days, as others have mentioned.
It is strange, I never had to do that with my previous Moto's.

It's the new normal.

After factory reset, connect to the internet.

Question Have you unlocked it yet?

Hi I'm trying to unlock the bootloader, but when I log in to the Xiaomi Unlock Tool, I never received the verfication code that's supposed to be sent via a text messages to my linked US phone number. Other text messages went through fine so either XIaomi didn't send the code or my carrier (AT&T) blocked it. I tried a few other numbers and none worked. Did you guys need to receive the text message to verify your account when using the Unlock Tool? If yes, did you use a Chinese phone number or something else? A tried 4 different US numbers and none of them could receive Xiaomi sms. Thanks for your help!

Hi! How do I know when it's passed time enough to unlock it? Do I have to verify from time to time on the tool?

Sorry but I must be doing something wrong and different from the way I always did unlock bootloader. In Android 12, With Vol down + power the cell phone enters a different screen "Bootloader" that always allowed unlocking.
mi unlock software does not allow clicking the unlock button, fastboot devices and adb devices commands do not work in this mode.... How to unlock with these changes?

Run the unlock tool again, it will tell you how many hours left. Normally it tells you that 168 hours left at the first successful attempt, it also tells you do not logout miui account or try to login another account on your phone. Just be patient.
