SIM Unlock Reset by HTCDev Bootloader Unlock

Basically, I have an ATT branded M7 that should have been carrier unlocked. First thing I did was complete the HTCdev unlock to install TWRP and supersu. I completed a SIM swap from a mini-SIM to the micro-SIM for this phone and it is asking for the network password which the provider is telling means that it is not carrier unlocked? Could the HTCdev unlock caused this? Seems like the SIM unlock is in a different area of the boot loader that requires s-off so I think no. Need to contact the eBay seller but anyone have any other suggestions? Is S-off and unlock the only option for a permanent SIM unlock?

Bootloader unlock and s-off are not related to sim-unlock. You probably got scammed by the seller, but sim-lock can be removed easily using a sim-unlock code which you can buy online (for really cheap). So it might not worth wasting your time contacting the seller.
There is another method to sim-unlock that require s-off(sieempi)
Sim-unlock is permanent even if you unlocl/relock bootloader or if you turn security on/off (s-on/s-off)

Thanks for confirming. Is there anyway to determine if it has been hardlocked?

what are you talking about? Hardlocked?

Something about if an incorrect code 10 times there's another layer of locks (found AT&T page that references PUK and PUK2 codes). Are those different than the carrier lock we're discussing? Found a cheap code on eBay. Ordered it, will find out shortly I guess.

AFAIK (I'm not an expert on this) PUK codes are used to unlock the device when a wrong PIN was entered to many times in an attempt to access the device. PUK (Pin Unblock Key = Personal Identification number unblock Key) locks the device on a lower level or/and the sim card can become locked (preventing access to data stored on the card) but this have nothing to do with sim-lock that are locking your phone to a specific carrier.
Im not even sure if PUK is still used, ppl just reset their PIN using their google account or they are performing factory reset....
purchase the sim-unlock code, insert the new sim card, enter the code when prompted.

Thanks for the explanation. I did manage to test the new SIM in another phone and it worked and another known good SIM resulted in the same error (new info since OP). Maybe I should have paid more for 15 minute service... ?

Purchased unlock code did the trick.

Wrong Imei

So i bought an at&t XT1097 from ebay and it came with sim locked, i tried to unlock it with no succes via at&t because they told me the imei was not in their database.
After looking at the imei displayed on the box i found out it wasnt the same displaying at the phone (i checked this imei and this was the original imei). So now what should i do? I have my moto x rooted and bootloader unlocked still i dont know if i should just return the phone since i live in Chile and bought on the USA, or try to upload the correct imei.

well as far as i know if it was att variant, then bootloader should not be unlocked, as att isnt allowing it, your device seems too be from a diffrent carrier, i guess xt1097 is not only own by att, retail ca, retail brazil and many others carriers also use xt1097. search by the imei might be you find something help full, and also check sim tray, it contains the original imei also.. you can also check imei from bootloader, just boot into bootloader and press volume down and select barcodes from the menu by pressing volume up. last thing you can do is RMA

It IS an at&t variant, i just unlocked the bootloader via sunshine. The sim tray doesnt contain the imei either and in the bootloader barcodes it shows the IMEI that im unable to unlock.
What is RMA?

The barcode imei is what the real imei is.. Box imei might be different, so if you have unlockbootloader and imei is not on database have you tried 3rd party unlock providers? I got mine in 3$ from unlockbase.. Give it a try.

Ive tried to unlock it via 3rd party, where most of them refunded me claiming that they couldnt get the unlock code. Its all so weird since now at&t says i cant ask for the unlock code since its attached to an account (previously they said it wasnt from at&t), and now i asked for the owner to try and get me the code.
I really hope i can get the code, im using a really bad phone right now.
Thanks for the help!

Seems suspicious. Is it possible the phone is stolen and has had the IMEI changed?

OEM Unlocking Greyed Out?

Perhaps I am just misremembering, but on NBD90Z, if your bootloader is already unlocked, should the developer option for OEM Unlocking be available or greyed out? Mine is greyed out (Pic attached) and only becomes available if I flash a 6.x ROM.
Tinfoil hat backgrounder....
I recently wanted to verify my carrier unlocked status on my Nexus 6. I popped in the Verizon SIM from my recently purchased Pixel, which worked fine. I'm now worried that however Verizon is able to force OEM lock onto the Pixel has now been set on my N6 and if I relock I will be unable to unlock.

@mattfrazer,
Yes the option is grayed out on 7.0 if your bootloader is already unlocked. I'm on Fi, my bootloader is unlocked, and it's grayed out on my N6.

No carrier to my knowledge can force lock a bootloader. Once you fastboot oem unlock it, it will stay that way till you pass the fastboot oem lock command.

I understand that. My worry was not that lock would be force enabled, but that the option would not "ungrey" if I were to choose to lock the bootloader on my N6 again. Either I hadn't paid close enough attention post 7.0 upgrade, or hadn't gone through the 2 step unlock process since running 6.x to notice the option greys out if your bootloader is unlocked on 7.0. I must not be the only one as the description under the option is changed in 7.1 to say "Bootloader is already unlocked" instead of "Allow the bootloader to be unlocked"
Thanks again to you both.

there are 2 possibilities . 1 : your bootloader is already unlocked(check it by going to fastboot) 2: turn on USB debugging ON
im sure your bootloader is already unlocked
cheers

Thats a good question. I have been away from VZW for a while now but did they have an N6 branded to them? if so, did they removed bootloader unlock like they do with HTC phones branded to them? if you did buy one from google or a non branded N6 carriers have zero control over it so in theory you can lock and unlock the bootloader at any time regardless of the carrier you are using for cell service. I personally never had to go back so i never noticed the greyed out option.
But thanks for pointing this out.

It is gray if you are already unlocked so you dont hit that before you fastboot lock if you are relocking. Doing the slider first can be bad. It was a changed in N.

No, there wasn't a VZW branded N6. In the US, only AT&T had a branded N6, and FWIW it was carrier locked to AT&T. Usual rigmarole to get it SIM unlocked. This version had an unlockable bootloader, just like the Google Play Store version.

So we can simply lock it again, without having to tick it or anything?

Yes there was. Vzw was the last of the major carriers to pick it up though.

Question Is Unlocked the same as Unlocked Bootloader?

Okay, I recognize this is a stupid question, but because I don't see an answer I'll go ahead and look stupid by asking it. I have the SM-G998U1 (Snapdragon US) and I purchased an "Unlocked" version, which I know means it's not tied to a specific carrier. However, as others have said, there is no "OEM Unlocking" option available in the US devices, I presume that the unlocked bootloader is different than "unlocked" in terms of the carrier, right?
I'd like to root my phone and be able to switch ROMs, but I need to be able to enable "OEM Unlocking" before that's possible, right?

correct.
an unlocked bootloader will allow root/rom.
that is completely different from carrier unlocking, which just ties the device to a specific carrier and has nothing to do with root/rom.

Thanks, I appreciate the clarification.

Given the issues the new Samsung devices are having even if you can root give at least a few months under factory warranty to make sure it's ok... or risk picking up the full repair tab.

Ok, another question about the missing OEM. How can I get into bootloader mode if OEM is missing...? Is it locked out...? Every time I click "enter" for Bootloader it simply reboots back to normal mode and I do have my S21 plugged into my laptop. What am I missing?

Need Help with bootloader unlock

I bought a new Pixel 4 xl when I tried to set it up, it gave me a notification " Your device is managed by your admin". I tried to enable OEM unlock but it was grayed out. I updated it to Android 12 beta I don't see the notification anymore but still can't enable OEM unlock nor even unlock the bootloader.
I want to unlock the bootloader is there any way to do it?
The phone is carrier unlocked it accepts every SIM card on both Physical and esim.
Thanks in advance.

Are you sure it's not an unlocked Verizon or T-Mo 4XL? They can be carrier unlocked but still be bootloader locked and I'm not sure if there's any way to tell by the model nbumber or IMEI.

Hmm there is the IMEI will have VXN on it or the serial number will probably show it and such has it
It probably lies in the about phone settings

Just as an aside, I got my 4 XL from T-Mo when they had a sale and couldn't get the bootloader unlocked, but the Soli chip went bad under warranty, so when I sent it back to Google, they sent me an unlocked (both carrier and bootloader unlocked) replacement.

So oem unlock is disabled?
Have you tried resetting the phone?

No, I started with a T-Mo oem locked, but Google sent me back an oem unlocked replacement.
My Soli chip went bad after just a month or two.

Try resetting the phone then check that setting
Could be that google had some type of admin on that is preventing OEM unlocking

Because you are BL locked the only two things you can try are a factory reset from recovery, and flashing a full OTA from recovery via adb. If that doesn't work, I'd be trying to get my money back.
Since your IMEI is permanently stored in a school or company database, the admin error will likely return when the device phones home (at first boot when wi-fi is enabled) and from the sounds of it, a policy has been set to prevent bootloader unlocking. That phone may be new to you but it is likely black market.

Now I understand the problem. I have tried the reset option and full OTA update in Android 12 the error isn't here anymore but OEM unlocking can't be enabled.

Yep. Looks like you were ripped off and will never see the full benefits of having an unlocked phone. Since it was "new" I would be getting my money back.

Oh thank God I came to know this before I buy the phone for myself. The problem is actually happening in my Uncle's phone.

Might have the Verizon variation
