sm-n920t relocking via modem - T-Mobile Samsung Galaxy Note5

OK, this is going to sound weird but here goes. I know generally that once a phone is unlocked.. it stays that way. This is the first time I've ever experienced anything quite like this. I purchased a n920t used and unlocked.. once I tried the note 7 port, found bugs with different services crashing like "enhanced features".. I went to flash the n7 rom after a wipe. Didn't like that so decided to flash back the stock image.. the phone restarted saying it was Sim locked and to use the silly t-mobile app to u lock it. Well I'm in Canada, won't unlock or even try via WiFi and you must have a connection to their data network to try.. purchased a remote unlock service.. unlocked no problem. Played around trying to debug the note 7 port and tried a couple of older rom ports for the phone and relocated again. After I spoke with the tech that was unlocking my phone AGAIN.. he said that the new "remote unlocking" type phones unlock via the modem... long story short.. you have to be very careful that you don't load a locked or blocked modem via rom image or you will wind up relocking your phone.. at least that's been my experience. Of anyone else has had this type of problem with the new style of unlocking.. please chime in.. I would love to know how deep this problem goes and if this is going to be an ongoing problem if modem change is necessary.

[Q] Bought used, this is a very hard puzzle

Hey I bought a used Samsung Galaxy S 4G for $110, and wanted to make android apps.
I know a lot of programming stuff, but it doesn't seem to help me much to fix this phone.
OKAY THE LIST OF PROBLEMS/SYMPTOMS
-Doesn't register SIM cards, doesn't even notice them! I can't use the phone like this.
-Stuck in airplane mode if I put it in, requires factory reset to get out of.
-Back speaker for music doesn't work. Earbuds work.
-MicroUSB port is fine, charges, but usually won't show up on my computers. It gave me a "USB Malfunction" error two of the times.
-IMEI and baseband show up in phone as "Unknown."
-Voodoo lagfix is installed? My buddy said this phone isn't even supported.
WiFi, MicroSD and apps all work, it seems fine otherwise. Factory resets do not fix it! Even the power+volume buttons one, where I find the voodoo lagfix crap.
I bought it from a girl, and I think her derpbag boyfriend maybe flashed Vibrant's firmware or did something wrong to it. I might have been ripped off.
Can anyone help me out? Know what to do? I will appreciate it!
First thing you can do is follow the second link in my signature and flash with bootloaders. Missing IMIE is a problem only ODIA can fix.
How do I do this without my USB port connection option?

You said your USB works... just shows as an error. I give tips on how to help with this situation in the Guide.

YES You were right, I followed your guide and got the phone to do new things.
It asked me for a SIM card and I haven't put mine in, but the IMEI number is BACK and ready. I didn't flash bootloaders yet, but should I still?
The phone's speaker still doesn't work, maybe I can't save that.
I got lucky, I tried plugging it in maybe 10 times I finally got it in download mode, so that's awesome.
Should I flash bootloaders? And what is the next step to possibly fixing the speaker?
I will probably want to root then unlock to use for my AT&T. I won't get a data plan tacked on this way, right?

If you're already on Gingerbread (You can check by going into settings > about phone) then you don't need to flash bootloaders. If you're on Froyo, then yes flash the bootloaders.
If you want to unlock your phone, click on the "SGS4G Unlocker" link in my forum signature. It'll get you your unlock code, which you can use after you insert an AT&T sim into your phone.
I'm not sure whether they'll tack on the data plan, but if AT&T works like T-Mobile, they'll require customer authorization to add any features to your account.
Well hey AWESOME.
I did flash bootloaders, didn't notice any difference.
THEN I went and tried to unlock it, the sdcard could only be read and not read/write from the Terminal emulator.
So I rooted it even though the root checker said it was rooted, and I did somehow have "superuser" already installed.
Now I also unlocked it afterwards, and it's working with my SIM and phone contacts. I sent a text and it's too late to call anyone today, but I'm expecting it to work fine tomorrow.
Your guide was fantastically helpful and easy to follow. Thanks a lot man!
The back speaker doesn't seem to work still, but I'm still counting it as a victory.
I recommended flashing bootloaders as a precautionary measure. Yes - you were already rooted. Glad you are up and running.
Maybe you can try replacing the loudspeaker if you cannot get it to work:

As for the AT&T thing, they can't find out that you are using smart phone since they don't have T-Mobile's list of IMEIs, so they won't automatically charge you with a smartphone plan. Also, if you previously had a 3G data plan with that AT&T SIM card you are good. However, if you don't, you need to turn off packet data and roaming at Settings --> Wireless and Networks --> Mobile Networks.

Flashing a carrier rom from stock

Hi,
I'm currently on the latest stock ROM (SM-920F - MMB29k.G920FXXU5DQA7)
I'm in the UK and am looking at moving from Tesco Mobile to Three as I don't get any signal in my house and want to use WiFi calling.
The only way to get native wifi calling is to have bought the phone from the carrier (ie to have their ROMinstalled) so I'm thinking of flashing my phone with the three ROM, the problem is I don't want to lock my phone so that it will only accept a three sim.
Can anyone confirm where how the sim lock is activated? Is it done in the ROM or do they do something over ADB to lock the sim?
Bump
Don't think it would lock your device because I thought of doing the opposite years back. I thought if I flashed an unlocked rom my phone would be unlocked, it wasn't. So an educated guess would say you will be fine. But then again I'm not 100%. Try it, you could always flash back.

OEM Unlocking Grayed out on non-VZW Pixel 2.

Hi!
I originally bought an unlocked phone from Google and I had zero issues unlocking the bootloader, rooting, etc. I was issued a warranty replacement for an unrelated issue.
I inserted my VZW sim and booted up this new phone. I was able to check the OEM unlocking slider and enter my pin. When I rebooted to fastboot and tried to unlock, I was unsuccessful. Booting back into android showed the OEM unlocking option grayed out.
What gives? What can I try?
Thanks!
*Edit: Also worth noting - If I do a factory reset, the OEM unlocking option will be enabled already. If you try to unlock it in fastboot, it will fail. Rebooting again results in it being grayed out again.

So, it came with the latest build then, or did you update via OTA?
Something to try: factory reset, turn it off, remove the SIM card, and give it another shot without connecting to wifi and skipping all the setup stuff. It's a long shot, but worth a try.

It came with something older, but it wasn't working with that either.
I tried the factory reset thing with no sim, but still on WiFi. The settings app kept crashung.
It seems like the VZW sim somehow permenantly locked my phone. I've done like 5 resets, and sometimes the OEM unlock slider is already off, sometimes it lets me toggle it back and forth. No matter what happens, after running the fastboot command (and failing), it will be grayed out. Rinse and repeat.
Have you called google with your IMEI number to confirm that it isn't a Verizon phone?
I just returned an Amazon refurbished Pixel 2 for this reason. They claimed it was factory unlocked, but I contacted Google who informed me that it was actually a Verizon phone that had probably had been unlocked for different carriers during the refurbishing process. I am exchanging it for another. They are not able to check the phone before it is delivered to me, so I am just going to hope I get a non-Verizon one this time or try the exploit mentioned on the forums immediately before connecting to WiFi or Cellular data.

The only other thing I can suggest is to sideload that same build's OTA without the SIM in. That might get rid of any changes that the Verizon SIM may have made, as it will format everything before it installs. If that works, do everything you want to (root, recovery, kernel) before putting the SIM back in. That's all I can think of doing.

All of Verizon's phones are carrier unlocked from the factory, and have been for quite some time. But, as far as being bl unlockable, that's a whole nother animal. Definitely good advice to check the IMEI with Google. Verizon can also do that for you, and it might be faster. I thought of that too, but it was my understanding that warranty claims we're filled with brand new units, but repairs potentially got you a refurbished one, so I ruled that out. I've been wrong before :silly:

I opened a chat window with Google, and they confirmed that it is in fact an unlocked device. He also had me "screen share" so he could see the problem. So far, no resolution. I sideloaded the current OTA twice, to make sure it was in the a and b slots. Then I tried setting up the phone without a sim or wifi, which didn't work. I also tried wifi with no sim, that didn't work either.
If I try the fastboot flashing unlock command, when I boot up, the OEM unlocking option will be grayed out. Any time I boot up from a factory reset, the OEM unlocking option is already selected on.

First of all, could Google confirm whether your device was new, or refurbished? The second thing I would ask of Verizon is, whether the IMEI of your device has been registered to their network before you received it. I know it's a Google phone, but the previous owner, if refurbished, might have applied a VZW update from Google, rather than a global stock image or OTA, thinking that it would be a good thing. Then, realizing that they screwed up, relocked it and tried their best to return it to stock and send it back for replacement under whatever guise they chose. That's my best guess as of now.
My P2 came from VZW with the Dec patch, and the bl unlock wasn't greyed out. Didn't really matter because I could use the exploit out of the box without toggling it. But, once I unlocked it, the toggle went grey, and the phone still remains unlocked, even after the April factory image update (skipped Feb and Mar).
In summary, if your device is truly stock Google, you shouldn't be having these issues, which is a valid reason for a replacement. If it isn't, you have a valid reason for yet another replacement, refurbished or not, that IS stock Google. Press the issue...you paid a lot of money for it!

I spoke with Verizon. The only time this phone has been used on their network is when it was activated on my account a few days ago. Google says it's unlocked. I'm still waiting for their response. My current theory is that it some how got locked when it recognized the verizon sim, but I really can be sure.

Seems like I heard in the past that even play store pixel devices had to be bootloader unlocked prior to jumping on Verizon's network as it was making devices non bootloader unlockable.
So in other words, if your phone was on the vzw network prior unlocking the bootloader regardless if it is a play store pixel, you might be hosed... rma
Having the same issue, I bought this phone and it works on ATT's network but i cannot unlock the bootloader. Kind of strange. oem unlock is greyed out. Ive reset it 10 times. trying after every update connecting to the internet and not from sept 2017 all the way to latest update. nothing changed the adb unlock command just says unable to unlock

if you are on Sep 2017 update, dont worry about OEM unlock.
Side load the jan update, and unlock the bootloader.

If it's a truly a Google phone, you can put any SIM in it you want to and the unlock slider will be available. Putting a Verizon SIM in it won't lock it down. I've unlocked mine and a couple others for other people. All of them had a Verizon SIM in them at the time and the unlock slider was still available. If it's a Google phone (or supposed to be) and you've already tried factory resetting it, your best bet is to RMA it. Something isn't right with it.
I have the same problem - phone unlocked but needed warranty replacement, can't unlock the warranty replacement due to exactly the same behavior where the option is greyed out, and even if I flash an image and turn the option on, I still can't do a fastboot flashing unlock and trying to do so greys out the option again.
However, I am not even on Verizon. I've tried with a T-Mobile SIM and with no SIM. So the Verizon SIM is probably not even the issue.
Google couldn't figure it out and sent me a second warranty replacement phone... which has the same issue.
Hello there. Experiencing the same issue. It's clearly a software problem. I have a Google Store, non Verizon, and I have RMA'ed it twice and both units CAN't be OEM unlocked. It's clearly a software problem because:
On factory reset OEM unlock options shows up and can be toggled
But when you go to fastboot, issuing 'fastboot flashing unlock' will return an error saying it's not allowed to be unlocked
On the next reboot OEM unlock toggle is now disabled. Only way to get it back is through factory reset with wifi connection, but that brings us back to 1 and the cycle repeats.
I guess it's pointless to RMA the device again. Reading here other people are experiencing the same problem. None of the devices have ever been on Verizon and are straight out from Google Store.
Despite it clearly being a software problem, Google is sending me a 4th phone now. It's obvious they don't know what's going on.

Please help me with my pixel multiple issues ,WiFi problems and Oem unlock issue

So a few weeks ago I bought a pixel for my son from someone local. It was very cheap and my son was using it for school using his mobile data. Today I have then tried to use the phone as I await for delivery of another handset and am faced with some issues. First the phone won’t connect to the WiFi. It’s currently running Android 8.1.0 May security patch and no matter what WiFi wont connect. At times it will say saved network but won’t connect. I have tried to reset the phone but alas no luck. The other issue is that phone is sim unlocked and can use my ee and 3uk SIM cards but the oem option states “connect to the internet or contact your carrier”. Unfortunately I cannot get the person who sold me the phone and all I remember is he told me he bought it from Very UK. Any suggestions please to fix this?. I as under the impression only phones which are sim locked have locked bootloader and also any ideas on how to fix my WiFi thanks.

Seems like you've bought a Verizon locked phone. Those phones has locked bootloaders and recently there was a tutorial on how to unlock those bootloaders. So it can't be done on the traditional way. Here's the tutorial: https://www.google.se/amp/s/forum.x...unlock-bootloader-verizon-pixel-t3796030/amp/
You say you're running may security patch see if there's an update first to June. The non Verizon phones got that already on Monday.
Another thing you could try is to do a factory reset and don't restore any backups at all. Because some backups tries to restore previously remembered wifi. So try that and connect to the wifi. If all this doesn't work then you could try to enroll into Android P beta and see if that fixes it. If that doesn't work then it's an hardware defect. If you cannot get a hold of the person who sold you it then I'm sorry to say that's probably why he sold it to you cheap as he probably knew about the problems it was having. I personally would try to get a hold of him first.

Bootloader unlock has nothing to do with carrier. If you could use 3 UK Sim then you're fine. Unlocking bootloader is only needed to flash custom ROM with some exceptions. Are you able to turn on WiFi and see your wifi but not able to connect or does it not turn on at all?

Hi thanks WiFi can be turned on but it won’t connect. At times it says connected and just saves the network. Mobile data is working fine so completely lost, and now trying to flash the P beta.
Just tried android p and same issue. WiFi will try and connect and just end up with saved but it won’t actually connect. Any other ideas please?

Have you tried pressing the wifi name and then press forget and try to put in the wifi password again. Is it the same issue on all wifi? Like at home, school, friends home or only at home? If it happens everywhere then I don't have any more ideas. My thought would be that it's a hardware defect. Is there no chance of getting hold of the previous owner?

They would probably only need the IMEI number, but if it's out of warranty they'll refer you to a repair center. Wish you all the best and hope that they'll be able to fix it. Let us know what Google says if you do contact them. Keep us updated please.

Thanks will update you as soon as I have spoken to them. The person I bought it from did say it was only bought last year from Very UK and it also looks mint. Has anyone had any dealings with Google RMA with phones without receipt?

I just bootloader unlocked a Verizon branded Pixel 3 - how is this possible??

I mean, I'm not complaining. But I was incredibly surprised! I bought the phone BRAND NEW AND SEALED, from the current sale on woot ($170), and yet was still intending on returning it after I realized I had bought a Verizon variant, albeit carrier unlocked. Yeah, it's only the 64gb version, but I literally just bought this for testing, and as a backup. Actually bought a P3 from a friend that was in decent condition. A really close, trusted friend too, but unfortunately it just happened that about a month later the battery started exhibiting the dreaded behavior indicating it was starting to fail, so I decided to pull the trigger on the sale, not realizing it was a Verizon model. I went into much more detail about it in my post on Slickdeals: https://slickdeals.net/forums/showpost.php?p=146850461&postcount=127
It's also pink, but I'm putting on the Mint colored Spigen Neo Hybrid case on it anyway
So anyway, from all my collective knowledge about Pixels, and plenty of knowledge about (and hate towards) certain US carriers locking down devices, I wasn't expecting to be able to bootloader unlock this phone. Luckily I decided to open the box anyway and see if the OEM unlocking toggle was greyed out (which is what I fully expected!)... And it wasn't!? I still expected something, anything, to go wrong, but no, it actually successfully unlocked the bootloader (proceeded to factory reset as usual, etc)!! Unfortunately, it seems that the eSIM is still locked up and disabled, but like I said, for my usages as a simple dev'ing, testing, and/or backup phone, the eSIM isn't really important to me.
Don't think it matters, but I did this immediately upon opening the brand new phone, and it was on firmware PQ3A.190505.002 (May 2019, Pie). I mentioned it in my SD post, but the IMEI does start with 35, and checking it through Verizon's prepaid check system also indicated it as Verizon branded. I know that historically (on older Pixels, not even the 3, iirc), there was a [anecdotal] workaround where some owners would pop out the VZW SIM card before ever turning on the phone and they could then unlock the bootloader. Crazier for me is that I didn't even bother pulling out the VZW SIM card the phone came with before turning it on.
The only thing I can think, is that (and my memory here is foggy about the anecdotal posts) maybe when people were buying the phones from Verizon, those phones were actually turned on with then-active SIM cards, thus allowing them to "phone home" and permanently lock up the bootloader, at some point before ultimately shipping to the buyers. However, as these brand new Pixel 3's being sold are just leftover old, albeit brand new and factory sealed, stock, they were never turned on, whether at all or with active VZW SIM cards, at any point. When I initially turned on this new phone earlier today, since I left in the VZW SIM card included with the phone, I got a message pop up saying something along the lines of "we couldn't activate the device" or whatever.
So anyway, I wanted to say all of this because I'm always fascinated by flukes like this, where someone (me in this case!) is able to bootloader unlock a phone that should otherwise be completely unable to do so... Also attaching screenshots to show that it is indeed a Verizon branded Pixel 3 with the bootloader now unlocked. Note that it now shows current April 2021 firmware installed, but like I mentioned before it shipped with May 2019 installed from the factory, and I updated the firmware after unlocking the bootloader immediately after opening. Is there any explanation to this? Did I just get incredibly lucky? Does my theory in the previous paragraph possibly make sense? Or is there already a known explanation somehow and I just was completely unaware (and if so please let me know)?
final note: pics look like phone's screen is fuzzy because I haven't even removed the factory plastic wrap yet, lol. amazon glass screen protectors come tomorrow!
EDIT: LMAO! The listing on Woot now says in big bold letters, "The bootloader is LOCKED on these phones". Pretty sure it didn't say that when I bought it, so must be a lot of people complaining about it and trying to return! Not sure how I was able to do it though still... even if I couldn't, I would have just cited the lack of eSIM as my reason for return. Fully Unlocked != eSIM Neutered, lol.
Should I buy one to try to get an OEM unlock version?
Hey, i5lee8bit
I was poking around and saw this. I ordered one of these from the woot sale. SHould be arriving in the next day or so. Mine is the 128 GB version.
I'm down to try your process and see if I am able to have success too.
What method did you use to unlock the bootloader?

First of all, I would remove the SIM card before you ever turn it on, just in case. I didn't bother and it still worked, but just in case that somehow allows it to "phone home" and lock itself up.
I just did "fastboot flashing unlock" from bootloader.
Just skip through setup, connect to wifi, enable developer options, and check (hopefully) OEM unlocking toggle is not greyed out. Enable the OEM unlock toggle, reboot to bootloader. While phone is booted to bootloader, connect to PC (or another Magisk rooted Android device with adb / fastboot module installed), and use command "fastboot flashing unlock" without quotes. Should hopefully prompt you to confirm unlock bootloader / wipe data.
To reboot to bootloader, either shut off and then power on while holding volume down, or enable adb debugging and send command "adb reboot bootloader" without quotes from command line / terminal.
I saw that deal you mentioned, haha. Are you a SD user / browser? I think the deal popped up this morning or something. If it's indeed brand new and sealed, hopefully it works! Best of luck, I hope you manage to get the bl unlocked!
Thanks for the direction. Haven't done a root on a phone in a long time.
Indeed, I am a Slicker ha. Over there I am @Skullk. The name was taken here so I used an alternate. Been a long time lurker on these forums.
This was the Slickdeal https://slickdeals.net/f/14972183-google-pixel-3-128gb-not-pink-199-99-with-free-shipping-on-woot
I received the phone yesterday. Made sure no SIM installed. Battery was completely dead, that makes sense though as these are some older stock.
Hope to have some time this weekend to give it a try. I'll report back with my findings.
Cheers!
Dude! It totally worked!!
I feel like we got something here. Maybe since the phones batteries were completely dead for a while in stock? Or just starting with a fresh phone on whatever exact version these are out of stock.
Are you sure theyre not Google phones
that were jus set up with Verizon in their former lives?

Woohoo! Back a while ago, when I was still on AT&T, I was researching Pixel 4 series and saw that bootloader was indeed unlockable once SIM is unlocked (like Apple, SIM unlock is controlled on Google's side servers, but once whitelisted, not only unlocks the SIM but also "flags" the OEM unlock toggle to be allowed as well - unfortunately not the case for Verizon Pixels). Unfortunately I had problems with AT&T and eventually bought a factory (Google store) Pixel 4 XL and switched to Xfinity Mobile. Anyway, during all that research, I also saw that some Verizon Pixel 4 / 4 XL phones (iirc) were able to be bootloader unlocked as well. There were a few theories, one of which (again, iirc) applied to older gen Pixels - this particular one being that as long as the phones were never turned on with a Verizon SIM inserted, they could be bootloader unlocked (some theories suggesting doing factory reset gymnastics and stuff). But this didn't work for everyone (actually, it didn't work for the overwhelming majority of people - a lot of people suspecting lies / hoax / misunderstanding). But now I'm starting to think this theory may hold some water, though. Perhaps when you buy phones from Verizon, they're doing something on their end that essentially processes your account info to the IMEI of the phone you bought, somewhere in the backends of their systems. That, or maybe they're doing something with the SIM cards to set up for your account and turning on the phone once before shipping to you (I have no idea, I've never been a VZW customer). Either way, the phone's IMEI gets to "phone home" to Verizon thus locking the bootloader.
But since we're buying these old stock, never touched, never processed / activated into their system, completely factory sealed Pixel 3 / 3 XL phones that are total virgins to Verizon's systems (other than being preinstalled with a VZW SIM card), maybe that's why we can unlock the bootloaders. I don't think it has anything to do with the exact firmware versions they shipped with. I believe I remember seeing people on SD having bootloader unlocked on various firmware levels. Hard to say which thread(s), because the deal popped up so many times in the last few months, but I definitely remember seeing scattered preloaded firmware versions being bootloader unlocked.
Another theory had to do with a mistake on Google's end. Some people got lucky, some people got EXTREMELY unlucky. Some phones were manufactured and branded for the wrong carrier. For example, a phone manufactured for Tracfone ended up being locked to Verizon (not sure of the specific carriers and whether vice versa but you get the idea). But some people would get a phone that should have been bootloader locked down (OEM unlock toggle disabled) but still be able to do so. Not sure if the latter is related at all to how we're able to unlock these, but I doubt it. These were very small batches that got mixed up in manufacturing. Right now, we're seeing definitely Verizon locked phones, old stock, that all seem to be able to be bootloader unlocked. I really do suspect that there is a "phone home" process when initially setting up the phone that seals the deal with ending up with a permanently unlockable bootloader.
Now, an interesting experiment (that I wouldn't wish for anyone to try to be honest, lol) would be to have someone buy one of these old stock, brand new Pixel 3 Verizon phones, and initially turn it on WITH AN ACTIVE VZW SIM CARD INSTALLED. See if that permanently locks the bootloader. If not, maybe Verizon's side only perma-locks these phones up to a certain date (like their activation server sends some sort of command to permanently lock the bootloader, but that behavior of their activation server is only active during a certain lifespan of the device)? Either way, it would be interesting if smarter people could somehow use this information to come up with an exploit to bypass the initial bootloader locking mechanism, whatever it may be, and allow bootloader locking on future Verizon Pixel variants (though you'd likely be screwed once it's perma-locked).
On an alternate note, I absolutely hate that these carriers are screwing us, the end consumers and ultimate OWNERS of the device, for no damn legit reason. Ok, I can somewhat understand that they want to prevent modifications to the device to use their network (and by understand, I mean BARELY understand). But once the phone reaches end of life, ALLOW US TO UNLOCK THE DAMN BOOTLOADERS!! Otherwise, they should automatically chop off the sale price in half to whatever is the best current price from another vendor. F|_|CK Verizon and AT&T!

100% definitely Verizon branded. They're factory sealed, and come with a preinstalled Verizon SIM card. Also the IMEI starts with 35, and (unfortunately) the eSIM is locked and unusable. Like I posted in the OP, the box shows it's a Verizon locked variant.
Worked for me!
Hi, I too bought pixel 3 64gb from woot last week, I started the setup as well without taking the included sim card out. After completing setup, I can verify that OEM unlocking is not grayed out.
I am very noob to custom roms, but definitely interested in trying out the custom rom when the official support ends, Is there anything else I should do before popping in my Visible sim card in it, so that the bootloader stays unlock.
Thanks, long story short this worked for me too.
I ordered my pixel 3 from woot on june 7th when it clearly said "The bootloader is LOCKED on these phones." and got it today. I removed the sim card before turning it on, skipped most of the setup including WIFI, enabled developer options, and the "OEM unlocking" option was greyed out . Then I found a post about it needing to have internet access to enable that option - sure enough I connected to wifi and the option was live! I guess I should have mimicked your procedure exactly.
I then followed the instructions from here: https://android.gadgethacks.com/how-to/unlock-bootloader-your-pixel-3-3-xl-beginners-guide-0189128/
and the rest of the process completed successfully.
So, you did not do any special thing but just enabled Developer Options and the bootloader unlock was not grey? But mine was grey when I enabled Developer Options.

I didn't do anything else. It was greyed out right after I enabled developer options but after I connected to WIFI for the first time and went back into that menu it was active.

It's a little confusing, your question. Did you read the posts from the beginning? I mean the OP **specifies** exactly what he did... so when you say 'you did nothing special'... He says exactly what he did, would u call it 'special'?
it's impossible to answer your question, he did exactly what he said he did, what more do you want to know?

His posts are long, so I am not sure I got it correctly or not, but it seems that all he did was just enabling developer mode and ran "fastboot flashing unlock" in the bootloader mode. But that is a regular method that Google should have disallowed to work on a bootloader-locked device, so I wondered if there were some other "special" hacking-ish thing he did.
I thought I had tried that, but it was a long time ago, so just to be sure, I did that again now, and all I got was
"FAILED (remote: 'flashing unlock is not allowed')
fastboot: error: Command failed
Thanks to the OP, think I got the last one from woot. Did exactly as this post described and sure enough, oem unlock not grayed out.
It seems, as others have said, that when vzw disables oem unlock is when they 'set the phone up' for you at the store, or maybe simply when it connects to the vzw network with their sim.
I've unlocked and fb flashed to latest A11 non - verizon firmware, relocked bootloader, and am still able to unlock if I want.
Google sure does make it a lot easier to flash new firmware using fastboot. Especially compared to LG and lgup (only on windows), and patched dll's so u can crossflash, and one dll version for this, and another for that... meh.
Google even gives you an shell script that works with Linux Awesome!

Registered just to thank you for this. Bought a Pixel 3 from a B+H sale for my wife (who was really looking forward to her new phone) - we're in Canada, so thought I was screwed. Took awhile to get the USB drivers set up properly, but she's now got her new phone.
Thank you! It worked for me too for two Pixel 3 phones, one from B&H (software version PD1A.180720.031) and one from Woot (software version PQ1A.181105.017.A1). Here are the steps I followed (with android platform tools including adb and fastboot already installed):
1. Removed verizon sim card (just in case) before powering on
2. Powered on and skipped through Google setup
3. Connected to my T-Mobile tethered wifi instead of Verizon Fios home wifi (just in case)
4. Enable developer options, wait for "OEM Unlocking" to become not-greyed-out (requires wifi)
5. Enable USB debugging in developer options
6. Issue `adb reboot bootloader` from PC (or shutdown and use hardware keys)
7. Issue `fastboot flashing unlock` from PC
8. execute `flash-all.sh` from the official stock pixel 3 factory image zip from here: <https://developers.google.com/android/images#blueline>
a. This gets rid of Verizon's firmware completely
9. Wait for it to complete, reboot into bootloader
10. Issue `fastboot flashing lock` (erases user data) to re-lock bootloader
11. Booted normally and setup. OEM Unlocking is still available in developer options if I want it in the future.

So we don't need to download the blueline images that say Verizon and can just use the latest 11.0.0 (RQ3A.210705.001, Jul 2021) image instead?
I haven't done this forever, is there still a need for TWRP if we are sticking with the stock rom, unlocking the bootloader and installing Magisk?
