I have flashed both Resurrection Remix and HavocOS to my phone, but in both roms I get no cell service or data, sometimes my sim isn't even detected at all, and in HavocOS my IMEI went blank a few times. When I go to mobile network settings in both roms, the app freezes. When I used *#*#4636#*#* the phone information tab was completely blank. I use a Verizon sim card and it works perfectly fine in stock OOS, but I was wondering if anyone found a workaround for the cell signal issue in custom roms. Backing up the apns-conf.xml file and restoring it has no effect, and restoring the modem and efs in TWRP doesn't work either.

Hi, I think I saw you commenting on this thread some months ago about custom ROMs too, right? Im trying to install a custom ROM to degoogle myself, but Im have some questions before doing so. I tried searching for some answers but there doesnt seem to be any custom roms that are supporting the GM 1925 variant even now :(

I was wondering after you install a custom ROM, do you lose dual sim functionality? Cause from what I know, this debrand to EU firmware essentially restores dual sim functionality from what I've read (but I havent tried it). Hence do normal 7 Pros (non-sprint/ t mobile) lose their dual sim functionality after installing a custom ROM, or is this solely a GM 1925 issue?

In addition, I also wanted to try out Lineage OS 17but I heard from OP that he didnt get it to work and Lineage OS 16freeze from time to time. Do you have any issues with Lineage OS if you've tried it?

Thanks in advance

Help on Converting Oneplus Indian to Global

I recently purchased oneplus and it turned out to be indian version.

Can someone guide me on converting oneplus indian version to global version.

I am not rooted and would keep it this way.
Reason for conversion is to remove Login to Oneplus from settings. Its very annoying. I trying flashing update file from oneplus canada and it still did not remove this.

Thank you

To install a 7 Pro (non-5G) ROM on the 7 Pro 5G:

Use this tool to extract the payload.bin from inside the rom.zip, use fastboot to manually flash each image

https://github.com/cyxx/extract_android_ota_payload

  • fastboot -w flash system system.img
  • fastboot flash vendor_b(/a) vendor.img
  • fastboot flash dtbo_b(/a) dtbo.img
  • fastboot flash boot_b(/a) boot.img
  • fastboot --disable-verity --disable-verification flash vbmera_b(/a) vbmeta.img
  • fastboot boot twrp.img
  • Mount /system and /vendor IN TWRP
  • adb pull /system/system/build.prop build.prop.system
  • adb pull /vendor/build.prop build.prop.vendor
  • Open each build.prop and change this line in both or whichever it appears:
  • Code:
    persist.radio.multisim.config=dsds
    to
  • Code:
    persist.radio.multisim.config=ssss
  • adb push build.prop.system /system/system/build.prop
  • adb push build.prop.vendor /vendor/build.prop
  • flash twrp from: https://dl.twrp.me/guacamole/twrp-installer-3.3.1-4-guacamole.zip.html
  • Reboot

Can't give you a 100% guarantee that every ROM will boot or function properly, but that is how I got Lineage 16 going somewhat well.
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.

Hoping to try this over the weekend, and tried a search but didn't find anything. Will this break Google Pay/safety net/Wear OS functions?

And just to confirm what I did find from searching here, this firmware will work with US Tmobile?

Not sure about t-mobile, if you read it tho it probably is correct. I know that I did this like 9 months ago and Ive still been going strong, (Sprint). Nothing has broken on my phone and I'm still able to access all the google features.

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?

    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.

    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.
