Since my original post I have:
Flashed PhilZ-cwm6-XXLRK-XEU-2.7-signed kernel in stock recovery to get original root and safe kernel.
Flashed GL_HYDRACORE_v5-4_STD kernel because I thought that's what I needed for PA.
Flashed pa_n7000-2.51-24OCT2012-192916 and followed instructions from Hydracore thread which said to flash kernel after done flashing new ROM and gapps. However - PA would not boot after that. I also tried pa_n7000-2.52-29OKT2012-101254-Utacka this way. Same problem.
So I decided to flash pa_n7000-2.51-24OCT2012-192916 this time but without changing the kernel. Booted fine this time and my phone flys now! Way faster than Stock ICS 4.0.4. It's nuts that official ROMs, by comparison, are so slow.
So I'm trying to understand how to know which kernels will work with which ROMs. So I've been reading the various stickies and
this thread in particular - very carefully. And I see the part about "WARNING: Do NOT use the below listed kernels for any CM10 build dated October 3rd or newer because your system will not boot.". I assume this why I was having issues after flashing Hydracore immediately after PA? And if I'm understanding this right, I could use the new HydraCore v7 with this PA JB ROM I'm on now? Is that because of this new MALI driver?
I did an EFS Backup after I did the original PhilZ kernel install but I never did a Nandroid backup while I had stock ICS. Should I just do that on any functional ROM now to make sure I have a full working copy of something to get my phone restored if something goes haywire? Is that the idea?
Also a lot of people seem to recommend flashing ROMs using PC ODIN. Is this considered safer or less risky than using CWM?
ParanoidAndroid JB imilka build has been great - but I noticed a few annoying issues:
1. WiFi signal seemed a lot better in Stock ICS than it does with PA. My signal is always "Poor" in my bedroom and I'm not very far from the wireless router but when I'm in the living room - it's excellent. Is this to be expected or is there something I can do about that?
2. Audio issues - sometimes I have to play with the volume to get speaker phone working after hitting the on-screen toggle.
3. None of the Voice Input stuff works. It just says "Initializing" and then "I didn't catch that". Also described near the end of the PA thread but haven't seen anyone reply with a fix.
4. No timer/stopwatch built into clock app. Can someone recommend a good app?
5. When I change the Slider shortcuts under Settings->Interface->Lock screen, they don't save. It always go back to default - Camera, Google Search and Unlock options only.
6. Looking for a nicer clock widget. Can someone make a recommendation?
Just wanted to point out that I love that it automatically had the StraightTalk APN configured for me. I know you're probably thinking - yeah so? - but I'm relatively new to android ROMing - just been lurking for awhile - so it was a pleasant surprised.
Any help would be greatly appreciated.
