Some of you may think this method sucks, but coming from a few WM devices prior to ERIS, this does work. I did the manual update, so did some others. The rest of the community opted for OTA. I did one more step though...wiped device after manual update. I'll provide instructions, but first let me explain why.

When reflashing any device, some data does not get deleted properly or even thoroughly. On my TP1 and TP2 I always (and it was recommended) performed a hard reset (wipe). Yes, this restores your phone to factory settings and you will have to set it all back up again. No you will not have to do the update again. You can try it and see if your issues are still there or you can deal with the issues. I skipped this step one time (TP2) and paid the price after setting everything up. I was experiencing all sorts of issues, but after wiping all issues were non-existent. Like I already said, all the issues that I've read about I am not experiencing.

To perform a wipe:
Turn off phone
Press and HOLD Volume Down, Talk and End
Select (highlight) RECOVERY with the Volume Down Button and press the END button
Phone will reboot and you will see a screen with an image of an explanation mark
Press and hold HOME button and press END button
A menu will appear in blue
Using the trackball, select the option to wipe device and follow the onscreen directions
When this is done, your phone will reboot.

If you do do this, atleast play with it for a few minutes after you have done the initial setup. In other words, if you were experiencing keyboard lag while typing start up something you can type in. So on, so forth. If everything works for you then install your apps. If after installing your apps you start experiencing issues again, then it is obviously and issue with the app(s).

Last minute note:
NO this will not harm your device. You are simply putting the phone back to factory settings.
