" I found that after I reflashed firmware L1657.6.08.06.00, it was possible to disable the Hisense Play Store, Browser, and some other built-in applications. So I took the following steps:
1) reflashing firmware L1657.6.08.06.00 that I downloading per my previous post
2) disabling and/or unstalling the Hisense applications where possible
3) upgrading the firmware through Settings
4) running back through @joygram's instructions in the OP
When disabling before step #3 above, it stayed disabled after the upgrade, even for the Hisense Play Store "
So now my Plans are to try with 6.08.06.00 and no i dont uninstal launcher. I have uninstall unknoun **** with unknoun name
Just be aware you might freeze apps that are essential and have to troubleshoot issues (or worse case, reformat if you brick the phone). E.g. I disabled apps found my eink button started to crash, but I was able to isolate the issue down to the floating navigation which I then reenabled.
