ENABLE 5G

  Dial: *#*#4636#*#*
  phone information
  Enable DSDS: toggle off and then back on
  reboot

---------------------------------------------
ENABLE DUAL SIM

  If DSDS setting unavailable:

  local term app w/root:
    su -c "setprop persist.radio.multisim.config dsds"

  or from pc:
    adb setprop persist.radio.multisim.config dsds

  or factory reset (lose all data)

  or possibly, install new firmware via newflasher (answer Y to keep user data)
  most data is preserved but new firmware includes persist files and maybe that resets this setting

----------------------------------------------
ENABLE VoWIFI, VoLTE, VoNR:

Install Shizuku, Pixel IMS

Shizuku
  start for rooted devices
  authorize app, Pixel IMS

Pixel IMS
  Gear (carrier Sim-1)
  enable VoLTE, VoNR, VoWIFI, LTE+

May uninstall Shizuku and Pixel IMS as long as SIM doesn't change.
Settings survive reboots but are lost any time the SIM changes.

-----------------------------------------------

eSIM:

  Dual-sim version of phone has no e-sim support, but e-sim cards work.

  5ber sim card with either 5ber App or OpenEUICC Magisk module

-----------------------------------------------

Delete system apps:
(really just disables, but more thoroughly than normal)

  Get Magisk & root

  Most apps:
    De-Bloater app from fdroid

  LinkedIn & Facebook:
    adb shell
    $ su -
    # pm uninstall --user 0 com.facebook.katana
    # pm uninstall --user 0 com.linkedin.android

experiments


Possible way to edit a system fs?:
unsin oem.sin  (example)
mount oem.img /mnt, modify, umount /mnt
- but what about verity? signing? -
fastboot flash ?partition_name? oem.img
in this case possibly
fastboot flash oem_a oem.img
or
fastboot flash oem_b oem.img


disable verity:
  Does not work. "Your device is corrupt" boot loop.
  newflasher fixes.
  No data loss but must re-do DSDS off-on regain 5G, re-flash magisk patched init_boot to regain root.
