Thank you for posting this! The only thing is the directions are not clear.Ok. I reset my phone back to stock, took notes.
I'm on 986u1. Android 10 ui2.5 magisk patched.
Remove your simcard before you flash your phone. You don't want it to pick a carrier yet.
Start with root folder. Vendor. Default.prop
Change active sim from 1 to 2
And ss to dsds
Go next into optics. Go into wwd carrier , customer.xml scroll down and change esim from false to true
Go into network.xml and add the same line csc feature ril support esim true.......
Change any other settings you wish to activate like real time net speed call recording etc...
Next find your carriers folder and copy the omc and any other files except customer.xml and network.xml , move those into wwd folder but rename the ones already in there or delete them which ever you want to do
Next. Rename the folder of your carrier to anything you want. Then rename the wwd folder to the name of your carrier. In my case I'm t-mobile. So the tmb I names to t1 and wwd to TMB.
Go to prison and swap names of folders in same fashion
Go into where your modem firmware and in oem file change xxxxxxxxxx....la/ss....to xxxxxx./dsds/...
Then go into imei folder and set the carrier from xaa to whatever it you use
Thats quick and dirty of it.
Power off phone after you modify files. Insert sim card and power back on,
After it loads you should now have sim manager under connection settings, when you first boot it will ask you to search for mobile plan
Can you please explain a few things?
1. "And ss to dsds" - Where exactly I need to change ss to dsds?
I couldnt find those strings in default.prop pr build.prop
2. WWD carrier is some Chinese carrier, do I have to use WWD or it could be done in own carrier? TMB?
3. There is no eSim string in customer.xml in WWD
4. "Go into where your modem firmware and in oem file change xxxxxxxxxx....la/ss....to xxxxxx./dsds/"
Do I leave the string with SS in in oem_hw.txt and add a second string with DSDS like on your screenshot or r replace it?
Thanks again for your hard work!
