Any hope of unlocking bootloader on Pixel 4? - Google Pixel 4 ROMs, Kernels, Recoveries, & Other

I picked up a secondhand Pixel 4. The seller said that this phone was purchased directly from Google and the only services ever used with it were AT&T prepad and Google Fi, never under any contract. But when I do 'adb reboot bootloader' the device state says locked and the OEM unlock option is greyed out. I have read that some Pixels purchased from Google end up bootloader locked after using Verizon service. If that is the case, is there any hope of getting the bootloader unlocked? Or maybe it got locked by some other means that I'm not aware of. Is there any way to get a history of carriers used with the phone via the IMEI in order to get a better idea of what might be going on?
Also, when I run 'adb shell pm list features' I do notice these lines:
feature:com.verizon.hardware.telephony.ehrpd
feature:com.verizon.hardware.telephony.lte
Does this mean that this is a Verizon model phone? Seems strange that it would have Verizon packages for a Google model phone.

You must have a sim inserted and data turned on for OEM unlocking not to be greyed out. I took a clue I guess from others by inserting my AT&T sim (still greyed out), rebooted (still greyed out), turned on mobile data (still greyed out), and rebooted. Then there was the glorious OEM unlocking option available.
For other clueless people who might read this: I immediately connected my phone via usb to my laptop, shutdown the phone, and held the power and volume down buttons to get into fastboot mode. Then from a terminal on my laptop ran 'fastboot flashing unlock', and the phone gave me the option to unlock the bootloader. adb and fastboot were previously installed.
I have seen other people mention the OEM unlocking option becoming available on their carrier version Pixel phones after inserting a not yet activated sim from another carrier. The latest mention that I saw was here in post #3

Sell your phone, then buy again with oem unlcok on

Same with my pixel 4 xl, i purchased on second hand market. I check the phone imei offline without other carrier sim and it was an at&t set. However, the bootloader option was not grey out. I quickly, unlock the bootloader after that and installed lineage os 18. . No luck for those whom got greyed out.

Bypass Carrier Activation Moto E Lte

I just bought a Moto E 4G LTE that is prebranded US Cellular (no contract). (XT1526 with lollipop 5.0) I don't need to use this device as a phone and do not plan on activating a carrier at any point, but just want to use it connected to my home wifi.
The problem is that the device will not allow me to bypass or skip the activation screen, and gives me no home button or option to even connect to my wifi. My previous Moto E (KitKat) simply allowed me to skip the activation and use the device..this one just keeps calling USC to activate over and over and the only option I have is to call or power off.
I have been searching the web all night and still have not found a solution (which granted may be due to my lack of knowledge in this area in general, and hopefully the solution is obvious to someone more knowledgeable). I tried touching the corners + volume up, but it hasn't worked and I tried different combinations, perhaps I have the wrong corner-order?
Anyone who can help me get this thing to let me in would be greatly appreciated! Thank you in advance.
Anyone? Surely there is a way to get past this activation screen...I'm not completely tech-inept and can follow instructions if it's something I've never done. Would unlocking the phone get past it? Can I even unlock it without being able to get to the home screen? Please help!!
It might be a US Cellular-only thing, as both my Verizon Moto E2 and Moto-Unlocked E2 can skip through the setup process without a SIM by just hitting Next or Skip.

Keep in mind that you cannot unlock the bootloader in 5.1 until you get into the settings, activate the Developer Options (by tapping Build Number a bunch of times), and tick "Allow OEM Unlock".
If you cannot get into the settings at least once, you will not be able to install TWRP or flash anything.
What you need to do if you are stuck on the activation screen is wait 5-10 minutes while the activation runs and fails. After some time you will have the option to connect to wifi. After that you can get into the settings menu.

Good to know!
By the way I don't see a way in the menus to enable GSM/WCDMA. Do you know how to do that?

Download "Network" or "4G Switch" from the Play Store. Open, scroll down a little and look for "LTE/CDMA auto". Change that to "LTE/GSM auto".
If that doesn't work, you might need to do the same workaround that is needed for the Verizon model:

My daughter's put in her password incorrectly to many times and it erased all data and it says choose language then hit start so I do and it says phone activation please wait while we activate your new phone. This may take up to 5 minutes. Emergency calling will not be possible during the remainder of setup. It has been stuck on this page for a couple of hours. What do I do?

Turn off, remove the SIM, turn on.
@xtermmin. Thanks for the advice but didn't work at all. I use the phone overseas and had unlocked the sim tray to get to work with another carrier since I while ago (4 to 5 months ago) with this method (http://forum.xda-developers.com/moto-e-2015/general/how-to-verizon-moto-e-2015-gsm-network-t3098953).
As of the morning of today, upon turning the phone up, it didn't want to connect nor Wi-Fi neither GSM. I made a factory reset and right after the Verizon logo screen the phone get on the wizard screen for a few seconds (5 to 8 secs) and then leave me on the screen saying "Pleas wait, this may take a few minutes". When I read your comment thought that could be, but there is no change after been done.

If removing the SIM doesn't allow you to get past the activation screen, then it sounds like something on your ROM might have corrupted or something. Have you tried reflashing the stock firmware?

I'm trying getting it done with this guide (http://forum.xda-developers.com/mot...e-restore-moto-e-2015-stock-firmware-t3044936), but can do anything after putting the phone on fastboot. BTW, I think before doing the factory reset the phone had an update (a security patch of may or april). IDK how it installed but well now I'm stuck there.
My screen present me this:

Dunno, you'd probably have better luck asking in one of the stock-flashing topics in the General forum.

Moto E4 Easily bypass Verizon activation
Remove the phones sim card. Thats it. Its that easy. The phone then allows you to do the typical android / moto setup.

This solution worked for me on my Moto Z Droid. I removed the SIM card after starting the activation process (phone ON). The phone went immediately to the wifi log in screen and I was all set! Thanks!

Debrand Huawei Y650-L01

Hi everyone,
I have recently bought a locked Huawei Y600-L01 (3 Ireland) because I was desperately in need of a phone (my own became hard-bricked without any reason apparently ). It worked only with a 3 Ireland sim I had bought previously, but not with my own Italian sim card. Since the phone asked me the unlock code and I didn't know it (I didn't even know it was a thing, since my previous phone was bought unlocked), I simply inserted my sim code ten times and successfully locked the sim on the phone.
Now, when I insert the Italian sim on the phone, it simply says that the sim is locked (despite not being actually locked, since I tried that sim on another phone and it worked perfectly).
As you may now think, I need this phone to be unbranded. The instruction for that phone are really hard to find, though.
While I installed successfully a stock Huawei V100R001C577B040 firmware version + kernel (phone still locked anyway), I can't seem to unlock the bootloader in order to unbrand the phone (at least that's what I understood it has to be done... or not? ).
I tried both with adb/fastboot and DC Unlocker
1 - adb successfully sees the device. If I type first adb reboot bootloader the phone gets stuck on the first boot screen without actually entering the fastboot mode. If I type fastboot oem unlock in this state it says that the operation has failed because the phone is locked.
The only way to turn back to normal is to remove the battery, wait some seconds and then put it back into the phone.
If I don't try to enter in bootloader mode and I just type fastboot oem unlock, <waiting for device> appears and nothing else happens.
I also tried fastboot -w, but <waiting for device> appeared even in that case.
I tried to apply for the code from the Huawei site, but a) when I dial *#*#1357946#*#* for the product number it doesn't appear anything and b) when I tried the Huawei Product ID generator no ID generated would work.
2 - DC Unlocker doesn't even recognize the phone
What should I do?
PS: I would rather not pay for the unlock code, and I also need to use the "locked" sim on the Huawei phone
_______________________________________________
EDIT: Phone can also go back to normal mode by typing fastboot reboot on PC

*Expert needed* OEM Unlock button not available, grayed out

I can't re enable the OEM unlock button. It says I have to connect to the internet or contact my carrier. I've read that it could be an security feature and I needed to wait 7 days for it to activate. I waited for 8 days, but nothing changed.
My phone is a Moto G6 plus, I had a custom rom on and just wanted to return to stock, but I mistakenly sent the command "fastboot oem lock" in terminal.
Can someone give me some help?

Bricked > MSM > Oem unlock toggled off and greyed..?

I bricked my device... Didnt flash both partitions I believe? Regardless after I unbricked using msm 2028 variant my oem unloick is now toggled off and greyed. Not quite sure if this might have been thew cause but I broke my screen ribbon cable connected on the logic board so I went to ebay to get a replacement. It came sim locked but with a unlocked bootloader. Before I tried flashing a custom ROM I rooted and unlocked my network without using the app provided by carrier (So device still shows locked in settings and APP but if I insert any sim the phone will read and activate on the network no issues) I flashed a custom rom and the network lock still shows locked but any sim card works HOWEVER OEM unlocking is now toggled off and greyed so I can not do anything with the bootloader and since I replaced the logic board I have a different IMEI than before and my old unlock.bin does not work. Is there a way to be able to activate oem unlocking again?
Go to your carrier, let them know. Inform of them of the new IMEI.
I swear there was another thread that used one of the debloat scripts from another O+ fone (the 7?) and axing one of the system packages enabled it (on other models, incl the N10 5G)... never tried it myself tho.

How To Guide Motorola G Power 5G 2023 root guide

Currently, RSA does not support XT2311-3 for unknown reason. However, I found a ROM for Tracfone, but the boot works with unlocked version.
Download: https://www.androidfilehost.com/?fid=10620683726822053015
MD5 60f8e629cbe7e969923c07538d6c3c7c
Bootloader unlock required. However, VPN disappeared after bootloader unlocked. You have to set up user account if you need VPN
Note: your phone is wiped during bootloader unlock process. Since RSA does not work with this phone at this time, you may not be able to rescue if something goes wrong.
Note: Titanium Backup does not work with Android 13. You need Swift Backup (pay $2.5 a year to use your choice of cloud service)
You should do it before initial setup. Wi-Fi connection and/or data connection needed for Magisk. Transfer the boot.img downloaded to your phone and patch it with Magisk, and transfer the patched boot back to host computer.
Now reboot the phone to bootloader or fastbootd
Code:
adb reboot fastboot
Flash patched boot
Code:
fastboot flash boot
Press space once, drag-and-drop the patched_boot onto command window, and press enter.
Post process:
Install the following as modules and you should install Fox's Magisk Module Manager
ADB fastboot
shamiko (you can setup Deny List but you don't have to enable because shamiko takes care of it)
Universal SafetyNet Fix 2.4.0
Systemless host within Magisk
liboemcrypo disabler is not required as it plays Netflix fine after these modules added, and it appears L1 on mine (good)
You can complete setup after root is done. Make sure you add Play Store and Play Services into Deny List as well as any app can detect root
How do you unlock the bootloader on this phone? When I copy & paste my device ID into the Motorola bootloader unlock page and click on "Can my device be unlocked" button, I get a message saying, "Your device does not qualify for bootloader unlocking".

Did you purchase your phone through Motorola directly?
I originally ordered a Moto G Stylus 5g (2023) from Amazon and tried several times to get the Motorola site to issue an unlock code. When I tried factory resetting this phone, I got a ROM not found error so I am returning this phone to Amazon. I then ordered a Moto G Power 5G (2023) directly from Motorola. My first attempt at getting an unlock code failed but I kept trying and finally was able to get through the process and now have the unlock code (sent via email).
When I tried to use fastboot to unlock the bootloader, I received this message "Check 'Allow OEM Unlock' in Android Settings > Developer Options". I have factory reset the Moto G Power 5g (2023) and am hoping the OEM Unlock option will be enabled soon. (If anyone has any 'tricks' on getting this Developer option enabled, please chime in)
If it helps, I used instructions from here: https://www.hardreset.info/devices/.../bootloader-moto-unlock-lenovo-motorola-root/
(They have a download for MFASTBOOT, which I did use but I am thinking the old FASTBOOT would work as well)

I got mine from Best Buy
Now there's a workaround for missing VPN
Get App Ops from Play Store and add sui (zygisk) module on Magisk
Check the list on App Ops and allow VPN on app needed
Moreover, Netflix works after USNF @Displax mod added, added Play Store and Play Services in Deny List, and Shamiko module added.
Mine shows L1 and Netflix (and cable TV app) work

I bought mine at Best Buy, but that shouldn't make any difference. It's the unlocked version for use on any carrier, so it should be bootloader unlockable.
I enabled Developer Options, but I noticed that "OEM Unlocking" is grayed out. When trying to Google this and find out why, I came upon a Lenovo forum where people were asking the exact same thing, and Lenovo's response was that the phone needs an Internet or Wi-Fi connection for 7 days before the "OEM Unlocking" option will become available(?!).
Now, I'm wondering if that's what's going on here, and why I'm getting the message that my phone isn't eligible for bootloader unlocking. I guess I'll see in a few days, LOL!

I know this is weird.
Mine takes 7 days and it's on internet/SIM active
Back then my situation was more difficult because even RSA was not ready for the phone (it says not supported). I needed boot.img for rooting
I think I'm on day 2 of waiting... It's only on WiFi as I need the SIM for my old phone. Kind of frustrating that it's not a more immediate result/change.
Yesterday was 7 days from when I bought my Moto G Power 5G, and I checked it this morning - lo and behold, OEM Unlocking is available!
I don't understand the reasoning/desire behind Lenovo's wanting to impose this 7 day waiting period, but it is what it is. Time to {hopefully!} go unlock my bootloader.

What a pain in the a$$!! I had to keep trying over and over before it would work. It worked the first or second time (gave me the option to get an unlock code), but I forgot to put it in bootloader mode, so I got an error. Then, I had to try multiple times before it would give me another chance to get the unlock code (kept telling me my device wasn't eligible for unlock). Finally got it unlocked, and then rooted!
