*#*#4636#*#* then Phone Information -> Set preferred network type. Choose :

NR/LTE/TDSCDMA/CDMA/EvDo/GSM/WCDMA

Or

NR/LTE/TDSCDMA/GSM/WCDMA

try this first
Obeid, I wonder if you can help me, my OP 9 pro, no longer has ability to recieve 5G from the time I installed the OS 12, C47 build. Before with the OS 11 I could with by using *#*#4636#*#* key. Any help would be grateful

Anyone have any idea for 8T, I try every method, but every time I come to ''choose device in PDC'' step, I cannot see/find device.
I'm not sure where is the problem

It worked fine for my on Android 11 using this method here and thank you for that, until the OTA Android 12.47 completely forgot about device will be wiped. But anyhow tried partial root with Magisk(LoadedSuccessfully) and load apk's from there no go, tried file manager also allow "install from unknown sources" no go, still searching around the device is currently on Android 12.47 and another OTA just rolled out again..smh But I did not accept it..
Any luck installing apk's would greatly appreciate, searched on xda did not find too much info on this pop-up notification images on conflicting packages.
The method on here worked flawless for me on Android 11, thanks!

    First of all, apologies for asking such basic questions.

    I have done something similar to this procedure on a 5 and a 6 previously, but now I am the proud owner of a 9 pro europe variant and would like to enable VOLTE as per your instructions.
    where do I find th apk's listed on your instructions list?
    What version of PDC is needed, I have one installed from 1 year ago is it the same one?
    latest qpst with pdc

    Thank you so much!
    I am still not able to complete the full procedure though.
    After step 11, the shell accepts the command but when I load pdc the phone does not show up in pdc.
    I used the pdv version in the attachment. Any ideas on why this is happening?
    try install latest qualcomm drivers
