Chrome is the stock browser now and Google is totally doing away with the AOSP browser. Some of you are not too fond of the mobile Chrome browser, and would much rather just have your AOSP stock browser back. There is now a method for installing this browser over Kit Kat 4.4.2. The sad news is that while you will be able to install the browser flash will still not be supported with this browser. Also bookmark sync will not work.
How To Install Stock AOSP Browser:
1. Download the signedbrowser.apk and place in your it in your phone's internal or external storage
2. Go to settings/security settings/ check unknown sources box
3. Use a root browser and navigate to system/apps and install Browser ProviderProxy.apk (you will get installation failed message which is normal)
4. Reboot device manually
5. Navigate to the downloaded file and install signedbrowser.apk
6. uncheck unknown sources from settings/security
7. Profit!
