Sims not connecting

[mike777z]

Hey Stephen,

I have noticed an issue with my sims not connecting. I'm using DJA0230 running firmware 20.3.c.0389-MR20 and using the latest tch gui unhide (2023.12.21). Telstra sims work fine but any other carrier sim doesn't work. The sim seems to find signal and register but wwan doesn't come up. Based on the logs, it looks like netifd fails to bring up wwan. The sim will only come online after rebooting the device 10-15 times. I've rolled back the version of tch to 2023.05.16 which fixes the issue and allows the sim to come online on each reboot.

I can't see any reason why tch-gui-unhide would cause that problem. If anything, I would have thought that 2023.05.16 could have caused an issue, because I changed the way VoLTE was configured. Apart from that, there are very, very few configurations that tch-gui-unhide changes - what it does is provide the mechanism to change configuration yourself.

I assume you have configured the Mobile Operator and Profile correctly on both implementations?

Can you compare the configuration from both the working system and the non-working system? You would need to run the following command in each:

uci show | sort > $(transformer-cli get rpc.gui.UnhideVersion | cut -d' ' -f4).txt

and then once you have copied both .txt files from 2023.05.16 and 2023.12.21 to your PC, use something like WinMerge or an online file difference tool to find the differences between the 2 files.

Otherwise, I am going to have to try and replicate your environment on my test DJA0230. Can you tell me:

• Did you reset to factory defaults between upgrading/downgrading tch-gui-unhide?
  • If yes, did you use the reset-to-factory-defaults script and what options did you use?
• Did you run de-telstra? If yes:
  • Which version?
  • Did you re-run when changing tch-gui-unhide versions?
  • What options did you use?
• What options did you use when running tch-gui-unhide?

The problem will be that I don't have a non-Telstra SIM to check. I only have AldiMobile or Boost SIMs.
