I was previously rooted and even after disabling root I could not do the OTA (it kept giving me a status error 7). After researching I decided to use ODIN to try and restore to a stock ROM for the upgrade.
I initially tried to use CI605_I605VRLJB_I605VRALJB_CL414933_HWID04_HW_Rev0406_low_ship_user as the firmware, but it caused my device to go into a firmware upgrade error.
I then used I605VRUEMJ9_I605VZWEMJ9_I605VRUEMJ9_HOME which got me back to stock 4.2, I OTA'd to 4.3, and using a previously downloaded OTA copy of 4.4.2 I booted into recovery mode and manually installed the OTA.
Since going to 4.4.2 (and I noticed it in 4.3) the Google Play store seems to load EXTREMELY slowly. I have Frontier FiOS and speed testing the connection shows a minimum of 25/11.36 Mbps for my connection. 4G does not appear to work so well either.
Could I have messed something up? I do not know why my stuff is working so slowly...
I tested speeds using SpeedOf.Me (website version) and got results of .5-1Mbps DOWN and .5Mbps or less UP. This is regardless of using wifi or 4G. I tested Wifi on my PC and got more than 10Mbps.
