Unlocked bootloader. (Oem unlock) now my pixel so won t recognize sim.

So I followed instructions on how to unlock bootloader on my pixel xl. And now I'm unable to connect to my network. I put the sim card in and it doesn't recognize it. I've tried multiple times to restart phone with no luck. So I did this last night and the only solution was to hard reset the phone once more. But that untenable that oem unlock function! So I unlocked it once more just now and I'm in the same situation! Should I proceed by unlocking oem and than do a hard reset? I'm not really sure how to proceed from here if someone could give me some insight i would really really appreciate it!!!

Are you saying that it isn't recognizing your SIM, and saying there is no SIM inserted, or are you saying that it's simply not applying the right APN settings and so you can't get cellular data and such
hi , its easy , just remove your sim card , and flash the phone again
Once you OEM unlock your phone a hard reset should not relock your phone. The only way your phone should relock is by using issuing the command OEM lock or OEM flashing lock.
There is an issue with some phones and systems where the "allow OEM unlocking" check box will come unchecked, this doesn't mean the phone is relocked though.
I got it figured out thanks! Now I'm just trying to install twrp but I'm not having much luck lol

You have to boot to TWRP from fastboot with the TWRP image file and then flash TWRP from within that recovery.

After 7 days still no OEM Unlock option

After 7 days of not turning off the device there is no OEM Unlock option running SD S9 Sprint. As I type, update time: 170:26. Any clues on why the option has not appeared mahalos
edit: so I've did some research and no oem unlock option for snapdragons is because their being locked down sad to say.
Cuz us is locked u can wait Months it still will not show up

Easier Way To OEM Unlock Via Fastboot?

This is potentially a MUCH easier way to OEM Unlock the S9.
I bought my S9 and waited the 7 days,did the unlock and accidentally let it wipe and reboot, so I had to wait the 7 days again. I tried the date manipulation trick and it never worked. Flashing a new bootloader wouldn't work.
Then I saw that Fastboot had an OEM unlock command, so I tried that, but it said it failed.
But then today, the 7 days were up again, and oem unlock finally appeared in my dev options again, and behold, OEM Unlock was already true!
I'm going to try flashing twrp and rooting later today, but I thought someone who may not want to wait 7 days could try this and see if even though it "fails" the bootloader may unlock anyway!
Assuming you have Fastboot and the proper USB drivers etc. Also assuming the device is not modified from its factory state etc.
Steps to attempt:
1. Turn off the phone.
2. Hold vol up, bixby, and power (to go into Fastboot)
3. From a command prompt enter: fastboot oem unlock
4. It will say it failed.
5. Attempt flashing the recovery of your choice via: fastboot flash recovery <recovery file>
Let people know in the comments whether this works!
Did this method work for your....

SM-960F/DS.
But I just got the "Only Official released binaries are allowed to be flashed" message, so I might get to try this method again myself, lol.
How exactly are you able to run fastboot commands when this is a samsung?? Odin is fastboot replacement and there is no way to make it recognize Fastboot. Please enlighten

Well, I just got the lock screen freeze and had to force a reboot, and when I did, I couldn't flash anything recovery or rom via Odin, so I tried using fastboot again to oem unlock, and it fastboot didn't even see it connected, so what you're saying makes sense.
Is it possible I used ADB instead? Does ADB have an oem unlock command as well? Or maybe the factory reset after the first toggle didn't set OEM lock like it normally does?
I'm not sure what I did, but OEM unlock was definitely toggled on once the option appeared. I'm going to play around with it a bit more.
On a side note, when I go into download mode, it still says OEM LOCK: off, but still won't let me flash unofficial bins. Would the RMM Prenormal have something to do with that?

That makes sense with what I found last night in another thread. I think I used an old version of the rmm Mesa bypass too, so we'll see what happens. In another 5 days...
This will not work. The large majority of Samsung devices (exceptions being the Galaxy Nexus and Nexus S) don't support Fastboot and there isn't any way to unlock the device using ADB.
The reason why your "OEM unlock" switch was already toggled was because, even after the data wipe, it doesn't reset. Your device stays OEM unlocked, but isn't RMM unlocked until the 7 day timer has passed -- so your bootloader stays locked until the RMM timer passes.
Fun fact: you can flash the "combination" firmware to your device and immediately enable OEM unlock, but you'll have to flash the normal firmware back and let the RMM lock timer pass still. You won't have to wipe your device that way.

This is the first time I've seen a clear explanation off all of this. Thank you for that!
What do I need to flash a combination firmware? Anda what is this combination?
Ps: sorry my english I am Brasilian. He...he..

I'm not familiar with it, but I assume he's talking about this: https://forum.xda-developers.com/ga...ollection-combination-rom-samsung-s9-t3782737
There are a couple other threads about it in the S9 forum.

So I kept the device on for 155 hours, and the oem option appeared again, so I booted into download mode: RMM prenormal (oem lock off still). When I started it back up, the oem option was gone again (still is). Does the 7 day period have to be without turning the device off?

Lol, so I'm at 182 hours uptime, but the OEM option isn't in dev options...do I risk going to download mode to see RMM status?

The above information was clear and helpful, but one query with respect to my case.
I have an Samsung S7 edge (SM-G935FD), i have flashed custom ROM successfully, but due to some reason I need to go back to my Stock ROM and I was able to do successfully.
The question is, seems still my OEM is unlocked even after stock ROM, will the OEM lock will happen automatically after 7 days, or is there any way to lock back manually.
Thanks in Advance
Samsung doesn´t have fastboot , it uses some kind of own mode only accessible via Odin. I prefer this way.
Also you have Prenormal state , this is some kind of security blocking by Knox, happened to me and had to wait 7 days.

Will appear within 5-7 days since you flashed stock ROM.

Bootloader Unlock SM-G960U

I'm going to keep this short and sweet. I have a Sprint S9 SM-G960U and its activation locked and been factory reset. My friend gave me his old phone after he upgraded because he forgot the lock code and does not remember what google account was used to unlock the device after it was reset from the factory reset boot menu.
Is it possible to unlock the bootloader...if thats even needed, root the device, and flash a custom rom to get around this?

AFAIK there is no reliable rooting / bootloader unlocking method available
Same question for a european SM-G960U (Snapdragon), where no "OEM unlock" option is available in Developers options.
I've just factory reset it, and am currently waiting for the tedious 7-day uptime period to pass, but am I keeping my hopes too up ??
Please share your results and whether or not it was successful. Thanks!
Well, no luck : no unlock option appeared, and the owner decided to get their device back, so I sadly don't have any result to contribue.

Bummer!!!

Shows OEM unlocked but not in fast boot mode.

Not sure what is going on here. I have a Pixel 3XL that let's me click the OEM unlock. When I restart the phone it still says it's shows the OEM is unlocked, but it shows it's locked in fastboot mode and will not let me flash a recovery image. It's a new phone and I have not put a SIM card in it yet. anyone been through this and found a solution?
If I had read the Wiki more closely I would have seen that I was only allowing the OEM to be unlock. The unlocking took place in another step.
Check it out I got the same thing. I just got a replacement 3XL last week and it's allowing me to unlock it are you saying it's not going to work if I try to unlock the bootloader because I have my original 3xl still and it's grayed out.. don't answer me either I'm surprised you didn't answer me you got the same s*** going that I do ?
