Would love to know how this phone is being used on T-Mobile. I have a sim unlocked Sprint GM1925 and T-Mobile says it is incompatible and will not activate on their service.
 
Why do we need to change persist.radio.multisim.config from double sim card to single sim card? After all, someone has already written that a 5g device can work with two sim cards with the correct firmware.
There isn't dual sim working on the device. People have tried just simply changing ssss to dsds and it doesn't work. Custom roms also need to be ported in such way or the modem breaks.
I was wondering if anyone else has gotten the android 11 update. I know its been out for a bit, but its not available for my 5G EU converted phone yet. Anyone else have this problem?
Android 11 isn't out yet but should be in a couple months
I'm using a GM1925 will there be any problem if I use this?
You shouldn't have problems if you follow the instructions and have the right drivers.

(Sorry for the late response)

The OnePlus 7 Pro 5G doesn't support dual sim and probably never will. It's been almost 2 years since the device came out and we haven't found a way to enable it.
 
I am just reading through here now since I just picked up a refurbed phone and I would really like some confirmation on this. If you can please clarify whether or not this works on the Sprint 1925 version with TWRP installed as I would really like to get off the stock rom and open up the device to other rom exploration. Your instructions related to this so far stated:

"Edit metadata to

pre-device=OnePlus7ProNR

It'll flash

Change dsds to ssss in vendor/build.prop

Extract 'rotation.zip' files to storage then place in root with file explorer in recovery.

Then run sh s.sh in terminal in recovery"

I am assuming that this is required to flash the modem on the device, but this process seems somewhat hazy to me. Can we flash any rom, then do the above to reinstall the 5g modem drivers? Can anyone add a bit more details to above description? Does this only work after flashing the European rom, or does it work just having the bootloader unlocked with twrp? Is there any other particular clarification required to truly liberate this device?
 
Decided to check back in and see if there was any updates here. Thanks for the info. How do you find this stuff out? I can never seem to find it. I feel like our 5g EU variants have been left in the dust :(, the OP7pro is already on like 11.0.8 or something
I've done extensive digging on XDA, Reddit and on Telegram. I'm betting it'll get it later this month (probably not) or in September because the device has bimonthly updates.

I don't think it'll be this month because OOS 11 is still hella buggy for the 7 Pro and on my 7 Pro has battery drain and had the resizing bug. My 7 Pro 5G on OOS 10.0.12 is really stable though

    To go back to Sprint stock use this:

    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:
      https://github.com/edgd1er/voenabler/archive/master.zip

      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://forum.xda-developers.com/on...otloader-unlock-sprint-oneplus-7-pro-t4042145

    Follow these steps in order or you will have to MSM restore to stock and try again

    1. Run TWRPadb.bat first
    2. Format Data after the successful flashing of TWRPadb.bat
    3. Reboot bootloader
    4. Run fastbootimages.bat
    5. Reboot



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

    Download the conversion tool HERE
    CONVERSION INSTRUCITONS:

    1. Unplug and power off the phone COMPLETELY
    2. Open the MSM download tool
    3. Uncheck SHA256 check
    4. Connect your USB cable to your PC
    5. Hold Volume DOWN and UP at the same time.
    6. While holding those keys, insert the USB.
    7. Keep holding those keys, click 'Enum' in the tool.
    8. Click start.
    9. Wait about 5-10 minutes, setup over Wifi, OTA to 10, PROFIT!

    It went smooth like butter

    Using this unlocked Virgin Mobile variant on T-Mobile and the process went beautifully. No signal until the EU ota completed. And 5G works for me as well. Now rooted using the Renovate 12.3 rom and all is good. Thanks for this tool. Honestly this device is way more versatile than other flagships.

    A. 
    So far my experience with cross flashing to the international 10 ROM has not been a positive one, when it done successfully boot, I am typically left without touch, or mobile radio function.
