I see that the device encounter problems like bootloops if I don't wipe cache.
Why wiping cache is required when flashing a kernel on HOX? What's unique about this device (or the method using fastboot)? Maybe a state encoded in bootloader?
This step is not required on other devices such as Xperia P or Samsung Galaxy Note 10.1.

Wiping cache get rid of "previous" stuff stored on phone. It may cause issues, especially if you going from stock ROM to custom and vice versa...

I know that... ROM yes, but Kernel?
The other day I was talking to a kernel guy at note 10.1 forums, he implied that there is no need to clear cache partition when flashing Kernels. And I told him it is needed for HOX.
Now I wanted to know what's the difference? We don't wipe cache for Kernels on GT-N8000.

You can flash kernels without wiping cache. Most of the time it works. But sometimes it encounters some problems.

For me causes boot loops.
EDIT: Why would it cause bootloops?
Sent from my GT-N8000 using Tapatalk HD
Because different kernels have different things stored so i am most sure u will have issues if u UV or OC had issues myself

I was just surprised about it, because a kernel guy told me that. He had a kernel with UV and OC interface. Why would he say such thing?
Sent from my GT-N8000 using Tapatalk HD
The app data in the cache is specific to the previous kernel. It's not always necessary to wipe it, especially if it's just an updated kernel, but good practice to do it anyway to prevent possible bootloops/app force closes.

As the title states, is it possible to flash a different Rom without having to reinstall apps?

Titanium backup is still the simplest and proven way to restoring previously backedup apps. And data is retained intact also.
You can also try backup/restore tool in rom cleaner thread by Patric.

I have done it with a few roms, just wiping the caches only. Make a backup first and try it.

Wipe cache and dalvik cache and you should be good to go. Make a titanium backup first of your apps and a nandroid. So if you encounter any problems you can either revert back to beta 2 or do a clean flash.

I did a superwipe+ext4...but that's just me. But anyways back to my point. B3 is a huge step up from B2 IMO. So smooth! Its been my DD since it came out. Check it out!

Everytime I reboot phone it says "Android is upgrading system". I understant that after you flash something it will do that. However this is happening on every re-boot. I am using TWRP2.2.2.0, running XquizitV32, Blue ICS modV3, inverted google now and Xquizit Honey comb battery mod.
If someone would be so kind to give me some info, would much aprreciated.
thanx in advance.
Not sure if it would matter, but do you have triangleaway and set to run after every restart?

It is just rebuilding caches. It's not a problem.

Dont know why it happens but it shouldn't. Its rebuilding dalvik every reboot. Maybe a script left behind somewhere?
Try clearing dalvik and cache in recovery and see if that helps.

Change to a different kernel.

It also happens when you fix permissions using cwm. Same Rom
That's not normal for every boot but it might be for this Rom. Good question.

That actually makes a little sense. It may be that the system didnt odex completely or correctly and is trying to deodex everything to correct what it sees as a problem.
I cant remember which it is right now but there is a setting in your build.prop that can tell the system to check for errors every boot and may trigger the deodexing process. I think its something like dexopt-flag=m=y
Prob not that one but itll be similar and related to dexopt.
Ill try to look it up later when I get home if no one else chimes in.

Sent from my SGH-I747 using xda app-developers app
Did you do a full wipe before flashing? It sounds like you have conflicting software running the processor crazy. In any case i would do a full wipe and reinstall the ROM again, if the problem persists then your phone may not like that particular ROM.

Try downloading romtoolbox lite (link at bottom) from the market and going to the second tab with cpu manager. Having downloaded these roms before some people set the minimum cpu really high to boost the benchmarks of their rom. If its high turn it down. It might help. Don't forget to slap that thanks button

Nope, actually it's the other way around, it doesn't support cm10, only cm10.1
I'm not sure why it doesn't work for you, maybe it's because of the new Mali drivers used in cm10.1?

So what can I do to get around this when I install it simply boot loops without logo. Thanks

That would be because Perseus doesn't support AOSP/CM based ROMs. It says so right there in the OP.

Note 2 kernel uses boot.img , other devices uses zimage file..they are different..so make sure what you flash has boot.img NOT zimage.
