From the logs it looks like the app updated correctly. @amit can you please clarify what is the issue?

Sep 12 11:54:47.061223 firestick-e6d8e21c5f1a041e local0.info pkgmgrd[937]: 13070 I pkgmgr-install-handler:[PackageInstallRequestHandler.cpp:2080] Completed installing package token 13066_webappkepler_armv7 status: 'Operation completed successfully '

If you think the issue is similar to package not updating, as your older package had higher version number, have you tried this https://community.amazondeveloper.com/t/installation-failure-on-kepler-device-with-customized-package-id/12147/9?u=vikrant_gimonkar1

Hi @Vikrant_Gimonkar1

I tried it with the same version, but the app never loads—it just keeps trying to start and then crashes.So i have no luck launching the app now
i also tried com.MYORGNAME.kepler.main ( still it fails to launch )

Version in package.json = “version”: “1.1.0”,
in menifest.toml = version = “1.1.0”

I see below in vscode putput**
