To go back to Sprint stock use this:

Sprint Restore:

Crossflashing to European 5G (GM1920):

Outdated method (REQUIRED BOOTLOADER UNLOCK):

Pie

(to set APNs on Sprint, go to *#*#4636#*#* and set the network mode to "LTE/CDMA/UMTS auto (PRL)" , then set your APNs and reboot.)

Input Sprint APNs:

Name: Sprint LTE

APN: x.ispsn

MMSC: http://mms.sprintpcs.com

MMS proxy: oap7.sprintpcs.com

MMS port: 80

APN type: default,mms,supl,hipri,ims,cbs,ia

Protocol/Roaming Protocol: IPv4/IPv6

Flash this in Magisk to enable VoLTE on Sprint:

If you update to a newer Pie build, you will need to reflash your modem from Sprint, here's a link: http://www.mediafire.com/file/x5g69dx5q64tibk/modem.img/file

OTA updates are fully functional.

The missing information in "About Phone" is normal and does not affect the function of the phone.

If Sprint is your carrier and you update to 10, you will lose APN access for the time being. (Though, humorously, the modem has been unified as of 10 and doesn't need to be reflashed after 10)

10

(Not recommend for Sprint users right now, as there are issues with APNs, GSM/NON SPRINT CARRIERS ARE FINE!)

*Modem has been unified so, you don't need to reflash the Sprint modem after update as of 10.0.4*

Aside from any potential Google SafetyNet updates that break SafetyPatch., this build works perfectly.

"About Phone" is still missing information.

How to flash (applies to conversion and stock restore):

Unlock your bootloader as per:

https://xdaforums.com/oneplus-7-pro/how-to/bootloader-unlock-sprint-oneplus-7-pro-t4042145

NEW LOCKED BOOTLOADER METHOD: 04/07/2020 (FULL SAFETYNET PASS):
