►►[AOSP] Official 4.4 - S4 Google Edition - v6.0-OTA - Feel the Experience of...

I've really wanted to use this ROM since v1 but it's been too buggy, due to the initial rom / kernel hiccups and then my own setup.

In case it's useful for anyone here's my method to get you to a stable install:

Modem:

I am on 3 in the UK and my recent modem for LTE / 4G is XXUEMK9 but I also believe there is a new boot loader (with KNOX), which I don't have or want. I had XXUBMEA on my 4.3 jelly bean ROM as well as the wifi fix, all flashed in ODIN. Flashed the MK9 modem but NOT the wifi fix for MK9 (I ran into audio issues initially when flashing the MK9 wifi fix)

Obviously you want to check what modem you need for your region etc. but I'd personally stay away from any updated wifi fix bins.

My ROM install:

1. Titanium Backup to save SMS and everything else of worth to ExternalSD

2. TWRP (2.5.3.1) for recovery: Wipe > Advanced Wipe > tick: dalvik, system, data, internal (make sure you have TWRP backups going to ExternalSD and that you have nothing of worth on internal), cache

3. Flash jamal's v5 ROM and then wipe dalvik cache at prompt. Reboot into recovery again and flash jamal's small v6 OTA

4. Boot to system, which takes a little longer the first time, setup as a new phone. Un-tick auto-restore backups.

5. Update Google Play (it'll update Google apps too) and then install Titanium Backup, restore SMS (KK4.4 wants you to set Titanium Backup as default SMS, say Yes, you can change after restore in Settings > Wireless > More...)

6. Your contacts should have sync'd and when you choose Hangouts, or whatever SMS app you want as default, you'll see your SMS

7. Install apps as needed and if so, restore data only from Titanium Backup

Everything works as it should for me. Been running a few hours and no reboots (see EDITS below), no FCs except on Google Play when installing loads of apps at the same time.

Note that Xposed installer doesn't work with ART (a replacement to dalvik in Developer Options) yet, so stick with dalvik.

Gravity Box works fine, pictures2sd and music2sd work fine (I kept the new Google Music settings as default, that is, store music to InternalSD and let the music2d module in Xposed handle the link to ExternalSD)

Can't think of anything else at the mo', only thing for me is the light grey toast notification for power options which I really don't get but I haven't looked deeper in the thread for any kind of fix, think there's a replace file fix but it's not pressing so not too bothered - see supervilllama's post here

jamal, thank you for the hard work you've done and for bringing us a pretty awesome and beautiful ROM, when installed from absolute scratch. Appreciate it.

EDIT: First phone call since building and a few mins in it reboots. Whoops. Not sure what it could be. Not having the wifi fix perhaps? Still kernel issues? Phoned again and no immediate reboot, talking for over 5mins

EDIT2: Had another random reboot when the phone was idle, screen off. After reading through some of the comments it looks like it could be trace remnants of faux's clock mod (which I used on my previous ROM)? However, I would have assumed things would be defaulted when doing a real clean install... either way, mpdecision off and ondemand set in governor in faux clock, no reboots for about 6 hours i think. also, incredible battery life so far...

EDIT3: Another reboot when idle...
