pulled from slimkat for nexus 5. its working now but its sadly not old browser from 4.3 but zoom works good now.
install works if you follow Ti2's guide
after succesfully Browser installed, then install BookmarksSyncAdapter-blackhand1001.apk for enable sync bookmarks. choose it in your settings enable sync browser and reboot
This worked for me:
1. Rename BrowserProviderProxy.apk in /system/app (I just added .bak)
2. Reboot for step 1 to take effect
3. Push Browser.apk to /system/app & set permissions to chmod 644
Don't get all too excited though, it's like they rushed it out - address bar doesn't hide, some advanced setting FC the browser, zooming is crappp & most important to me: it does not have textflow
