Default [GT-I9505][GUIDE] Updating FoxHound ROM 3.3 to 3.4 Diamond Dogs

Ideally I'd like to post this in the appropriate ROM threat, but as I've only just signed up, I only have limited access.
Rather than keep this info to myself, I thought this may be useful to others out there....

Original ROM thread: http://forum.xda-developers.com/show....php?t=2303239

Updating from 3.3 to 3.4 required quite a bit of reading and making notes to minimise the chance of having problems.
These were the steps I took for a successful install...

Pre Update
Backup backup backup!
Titanium backup, SMS Backup+, Whatsapp, Google contacts, etc...

ROM Update
Download Rom and copy to phone memory
Reboot in Recovery
Wipe Cache and Dalvik Cache
Wipe data if coming from another Rom (optional)
Select Zip and install / Flash Rom
Wipe Cache and Dalvik Cache
Ignore message to fix Root and Recovery
Boot and configure

Modem Update
Update the modem to either: MKE or MJ8
Download from: http://forum.xda-developers.com/show....php?t=2192025

Reboot in download mode
Use Odin v3.04
Load MODEM
Click Start - Flash modem
Reboot once again into Download Mode using (Vol Down plus Home button combination)
Flash Modem once more (You might need to install it twice for it to work.)
Once done,unplug then reboot device manually.
If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.

Problems: Phone freezes and sometimes reboots / Slow motion causes reboot
FAUX kernel solve the problems.
Use this and choose the kernel you like to flash.

Post Update
Following the above steps, I was able to successfully keep almost all the data and settings.
The additional main things I needed to do were:
- Reactivate/install Xposed Installer if you were previously using this.
- SMS Backup+ for restoring text messages.

Other Apps Installed
Having just moved over from an iPhone, these are a few apps I found useful:
NiLS notification - I use the widget on first page after unlocking
DigiCal - Calendar app and Weekly Agenda widget
Google Keep - For notes
Tasks: Astrid To-Do List Clone - My task list with repeat reminders

Problems (?)
Nothing major so far. Battery life has been great!
The only thing I would like to do is work out how to change/disable the default call screen image


Thank you for an amazing ROM! I look forward to the next update.

I hope you've found this useful... and if anyone has any tips/advise, please share!
