You're close!
Looks like you're using
ES File Explorer, so that's good...here's what I think you should try:
- extract the files from the
421-BrowserProviderProxy.zip file somewhere (i.e., on your SD card, like I believe you've already done)
- if you haven't already enabled
ES File Explorer's root browser function, then do this:
- press the menu (three vertical dots on the lower right of the screen)
- select Settings
- scroll to the bottom of the Settings screen
- select "Root settings"
- make sure "Root Explorer" is enabled
- check the "Mount File System" checkbox to remount the / and /system filesystems are writable (this will allow you to place the files from the 421-BrowserProviderProxy.zip file into the /system/app folder)
- press the back key until you're back to the file navigation screen
- next, navigate the folder where you've extracted the two files from the
421-BrowserProviderProxy.zip file
- press the
multi-select icon at the top of the screen on ES File Explorer's tool/function bar (four little blue squares with check marks on three of them)
- single-click the two files,
BrowserProviderProxy.apk and
BrowserProviderProxy.odex (the file names should change color after selected)
- press the
Copy icon on the toolbar
- now that you've copied the files, navigate to the
/system/app folder
- finally, click the
Paste icon on the toolbar to insert (paste) your new files (you might be presented with a pop-up warning asking if you want to overwrite--select okay)
Let me know if that makes sense.
Thanks!
