Check the firmware of the lineage as long as it doesn't over wright the modemst1 and 2 then it should be unlocked
My phone was purchased used off eBay. It said it was unlocked for any carrier. I receive it and popped in my at&t gophone sim. All was fine.
Until...I updated to 8.1. all of a sudden my sim card read invalid. Because it was a Sprint Variant.
Thankfully I fixed it.
I unlocked my bootloader, and installed TWRP, flashed Android Pie and rooted and things are fine now.
However, we had a new ISP installed yesterday and for some reason the 2.4 GHz will not work on my phone. The 5ghz works fine and the 2.4 works on every other device in the house.
Did not have this problem with the old ISP (at&t)
I've cleared my network settings and all that. I'm scared to factory reset as I don't want to go back to possibly having my sim card not work and the wifi issue not be fixed anyway.
Any ideas what it could be?

Read back through the thread im pretty sure someone found out rooting messed up the wifi and they fixed it i think
My wifi has always worked even with being rooted. My wifi still works other places and still works with my old ISP router (they haven't shut it off yet) it's only the new ISP wifi. (the 2.4ghz, the 5ghz works fine). And the 2.4 GHz works on every single device in my house. I'll search through the thread and see if I can find an answer. Thank you.
Quick question, still paying for my Sprint S8+ and it will not be paid off till Aug, I am traveling overseas in March, will using a 3rd party to unlock the phone (unable to payoff early now as I am a furloughed FED at the moment) cause any problems, i.e. not work when im back stateside and back on Sprints network. Thanks.
So I'm thinking about buying a ph-1 if I use this method to unlock the phone does it get ota direct from essential or would I still be at the mercy of sprint? Also do custom roms work on sprint version the same as the open version?
If you are unable to complete the unlock tool with your current Pie version, downgrade to 7.1.1 (check out the link in post 631) and run the tool again.
I was getting a 'no command' error using the tool on the April 2019 OTA. Doing the above fixed the issue.

Hey i have seen this error myself i still dont know whats causing it but the solution is to hold power then press volume up button that will get you to recovery mode and wipe data factory reset and reboot the device and continue on with the process. i think it might be a bug with the new update unlocking bootloader.
Could someone please re-upload the unlock tool? The download link on Google Drive isn't working any more.
Sorry my drive was getting full and i didn't think anyone still wanted it

Could someone please help me? I ran the unlock tool and got a few errors about not being able to write to a critical partition, but the script advanced sufficiently to ask me to enable usb debugging after the factory reset. However I have lost touch screen ability and have no way to get past the setup screen.
Any ideas? My phone was on a recent Pie build before I tried to unlock it.
I did just read a suggestion to run flashall.bat, but the phone did get downgraded to 7.1 and I need to go back into Settings to enable usb debugging again. I have no touchscreen working. Help?

12Thanx to Alu_Potato for nice directions. I have simplified this even more. No need to flash modem files seperately.
Take SIM out.
Pre-Reqs
1. Install Windows Device Driver for Essential Phone from here: https://storage.googleapis.com/essential-static/Essential-PH1-WindowsDrivers.exe
2. Install ADB/Fastboot from here: https://androidfilehost.com/?fid=746010030569952951
3. Download my Minimal ADB Fastboot folder, unzip, it includes unzipped build NMK24B & official 8.1beta & platform tools: https://drive.google.com/open?id=1pyOlQvkSGQWfrFHot_-avWnLee9r2jGR
3b. Put entire contents of my minimal adb folder (keeping things looking identical) into your Minimal ADB folder, located under Programs. Overwrite if asked.
5. Go to settings in your phone>about phone> and tap build number 7x to unlock developer mode.
5a. Go into developer mode and turn on OEM unlock and USB debugging.
The Process
1. Connect the phone to the computer.
2. Authorize the computer for USB debugging on your phone.
3. Turn phone off. Hold volume down and power simultaneously, until you enter Fastboot Mode.
4. Go inside your new Minimal ADB folder (in programs), hold shift key and right click (away from items, in white space) select "Open command..."
4b run "fastboot flashing unlock"
6. When the phone reboots go through the setup and redo pre-req #5
7. Repeat step 3.
8. Run "fastboot flashing unlock_critical"
9. Repeat steps 6 and 7.
10. Open Minimal ADB program folder. (Your phone is in Fastboot Mode). Now run the "flashall" file (not flashall.sh) by just double clicking the file. Will reboot when done. Scripts and commands are generating/running.
****Not taking flash? Restart bootloader (vol up), Try again****
10b. You have just flashed NMK24B.
11. Repeat step 6.
12. Repeat step 3.
12b. Hit volume up key until it says "Recovery mode" select power key. You now see a dead Android with his belly open. Next step.
13. Hold down the power button for a two seconds (keep holding) then press the volume-up button one time. When the menu appears, select Apply update from ADB.
13b. Open command line in your minimal adb folder. Run "adb devices" See that its recognized.
13c. Now sideload install by running - adb sideload "location of the Android 8.1 Beta zip" - Important: the quotation marks around the file location need to be there for this to work.
14a. Find location name by going into Minimal ADB folder. Right click PH1-OTA.zip, select properties, select security tab. *File Path is there at the top next to "object name"
14b. Type adb sideload "
14c. Then paste your file name (that you highlighted and copied) and add another " hit enter.
Go thru setup, connect via wifi, phone accepts sim!
***********Connect to WiFi & UPDATE TO OFFICIAL OREO BEFORE LOCKING BOOTLOADER************
Locking Bootloader after taking ota update:
1. Redo step 9 of "The Process"
2. Open command line in your Minimal ADB folder. Run "fastboot flashing lock"
That's all11This process came from hypnz, so give him the credit. Here is a step by step for anyone that needs it. I may have missed some steps with all of the re-enabling of developer options and USB Debugging. Basically, do that every time the phone is erased.
1 Enable Developer Options
2 Enable USB Debugging
3 Enable OEM Unlocking
4 Reboot into bootloader
a. adb reboot bootloader
5 Unlock bootloader
a. fastboot flashing unlock
6 Reboot
7 Copy Magisk to phone
8 ReEnable Developer Options
9 Enable USB Debugging
10 Reboot into bootloader
11 Flash TWRP
a. fastboot flash boot NMI81C-TWRP.img
12 Reboot phone
13 Reboot into recovery
a. adb reboot recovery
14 Install Magisk
15 Reboot phone
16 Install Partition Backup and Restore from PlayStore
17 Backup partitions
18 Copy backups to computer
19 Reboot to bootloader
a. adb reboot bootloader
20 Flash new modemst files
a. fastboot flash modemst1 modemst1.img
b. fastboot flash modemst2 modemst2.img
21 Reboot phone
Stop here if you want to stay rooted and with an unlocked bootloader.
22 Reboot to bootloader
a. adb reboot bootloader
23 Run flashall.bat
24 After reboot enable Developer Options
25 Enable USB Debugging
26 Reboot to bootloader
a. adb reboot bootloader
27 Lock bootloader
a. fastboot flashing lock
Here is a link to my dropbox with all of the files.

If anyone sees a mistake or missed step let me know and I will edit this message.9I have a few ideas about a possible unlock for the Sprint variant of the Essential Phone.
Summary:
Basically, it revolves around modifying the value of an item in the nv-data partition that contains the sim lock status.
This method is based on:
https://xdaforums.com/moto-x/genera...int-xt1056-t2825155/post54338871#post54338871
Possible Solution:
1. Getting a backup of the nv-data from a locked Sprint phone and an unlocked Sprint phone,
2. Comparing the items from my locked phone and another locked phone and finding the items that have same value
3. Comparing the items found in step two to the items from the unlocked sprint phone and possibly finding an item that is different.
4. Writing the value of the found item to a locked phone and seeing if it becomes unlocked.
How you can help make this solution a reality:
We need backed up nv-data from at least one locked and one unlocked sprint phone, here is how you can back it up.
1. Open the dialer and input the secret code *#*#3424#*#*
2. On this screen enter 000000 and tap confirm (very great for us that essential left the default msl value).
3. On this screen check the diagnostic mode and close the app.
4. Download and extract the nv-data reader on a PC [url]http://phonegeek.us/NV-items_reader_writer.rar[/URL]
5. Connect your phone, in device manager, a new Qualcomm device should appear.
6. Run the program, in the top bar: select the com port (it should be shown in device manager), check both of the boxes in the top bar, and click connect.
7. Now in the top bar click read, if the log says "Log message: > SPC is correct. Phone unlocked" you have done everything correctly so far. (The unlocked part has nothing to do with the SIM lock status)
8. Under "Range (Dec):" enter 0 to 07300 and click read (07233 seems to be the last useful value but a little buffer is good)
9. Save the file with any name you like and send me a private message with it.6
I was able to get this to work. Apparently you need to be on a build that allows you to flash the modemst partitions. Read what I did below.
This phone was running the latest 8.1 beta, and I would get stuck at "Flashing is not allowed for modem partitions" after unlocking the bootloader, and running the fastboot flashing unlock_critical command. I did go though the process to root with magisk so I could back up the modem partitions, which I think is a good idea. I grabbed the modemst files from jashenberner's dropbox.
I was able to flash the modemst files by first flashing the NMK24B factory image via fastboot.
This build is toward the bottom of this page: https://www.essential.com/developer/current-builds
Then I sideloaded the lastest beta build via recovery found here: https://www.essential.com/developer/beta-builds
After installing the beta I used this guide to install magisk:
https://xdaforums.com/essential-phone/how-to/guide-rooting-essential-ph-1-magisk-t3701976
I'm now using T-Mobile with the latest 8.1 beta on a "locked" Sprint PH-1. I can confirm that WiFi works fine as well.
Let me know if you have any other questions.5
