i think i found my problem. there was a wrong " in the "RESIN_HOST_CONFIG_dtoverlay" from a copy error. once i removed them and then formatted, it looked like it updated.
it is now "RESIN_HOST_CONFIG_dtoverlay": "\"vc4-fkms-v3d\",\"dwc2\",\"dr_mode=host\"",
just wow, something so simple and if you didn’t ask me that question i would have never found it (it was 100% pure chance i review it after pasting the code).
Yes @tjb probably in your case the issue was related with the dtoverlay. Glad that you found it!
As you discovered… the dtoverlay must be separated as an array!
Let us know if we can help you more 
I enabled support and sent the link in DM. I was reading the logs but I still couldn’t solve it.
Hi @khtmhai5, welcome to the forums! Could you please share a bit more context about your issue? Are your services also not starting? Could you also share the output of the command journalctl --all -n 100 -u balena so we can take a look at the logs?
Thank you
Hi @khtmhai5 did you manage to get the logs as my colleague mentioned?
To do so you can open the HostOS terminal on your device in balenaCloud dashboard. You can get more info about journalctl on balena here.
