When flashing a kernel you need to wipe dalvik cache only. So to answer your question no you will lose nothing from system/app or data/app. The update must contain a new kernel in order to overwrite your existing one.

[Q] paranoid note user wanting to install paranoid android

if you read my last threads you will know i mashed my other note to pieces....
on my desire i would flash roms 3 each week without messing the phone up, so after messing up my note through formatting through cwm while on ics i am a little/lot scared about doing it again..
so i want a little help if you guys would be so kind :laugh:
i dont have the new phone with me right now, but this time i am going to learn how NOT to brake the phone before i start playing with it.
so could you please walk me through this, explain to me as you would explain to a child LOL
so as i understand it, i need to keep to gingerbread then root it, go into recovery and flash the rom from there? do i use the normal phone recovery to do this or do i have to install cwm?
i am a little worried about using cwm again tbh, or can i use mobile odin?
i want to know the easiest way, the most fool proof....
damn i was never this worried with my desire.
your probably thinking "if you are so scared then why bother" right? its just the phone is so damn laggy, even compared to my desire which was built by cave men
cheers for the help guys, asuming i get some ofcourse :fingers-crossed:
Start from a gingerbread rom, then fully root it and install clockworkmod, next boot into recovery(volume up+power+home button together). First flash paranoid android rom then flash gapps, lastly wipe data, cache partition and dalvik cache. Reboot and enjoy

Yes, you can flash from one of the supposedly known safe ics kernels to speed the process up BUT if you want to be 100% safe in flashing to any cm9, start with a gingerbread rom.

Cool thanks, I will just do that when the time comes then, for some reason this phone is no where near as laggy as the last one, and I have all my apps I had on the other device plus more....

Lol yeah...i only had the phone a fortnight......on contract whoops lol
So is it still okay to root through cwm and then use mobile odin? Are there any decent roms out yet that have decent s pen usage?

I also just received my note from samsung after bricking it with CWM. I am so afraid I might brick it again trying to install paranoid android since I have to wait nearly a month to have my phone back in case anything happen.
Just one question, as long as I'm on paranoid android, can I just format or factory reset my phone through settings or recovery or cwm safely? Thanks a lot.

If you want to install paranoid, its cm based which means no touchwizz apps will work on it as they need the touchwizz framework. That being said, s pen still works fine and there are plenty of alternatives to the s apps (papyrus, memo etc). Also I've read that one of the devs is working on getting the s apps onto cm9 somehow, but not sure who or how its going. Also the cm9 kernel included for the rom is safe from the superbrick bug as its has the cap wlerase command disabled.
PA has a slightly different installation to other roms. I would highly recommend first installing stock rootable gb, root it and install cwm. Once that's in place perform factory reset.
Then download paranoid and g apps and copy them to external SD card.
Then FROM CWM recovery, you flash pa first by "installing zip from SD card", then do the same for g apps straight afterwards.
If you have any fc's or issues, enter back into cwm recovery and wipe cache and dalvik.
Boom, ready to go for full on paranoia
Its a truly great rom, very customisable and as ics should be.

Thanks ST, so am I right in thinking if I go the cm route then I don't have to flash the kernel first. It will do it for me? So all I need to do is root it and get a safe kernel?
Is there a free mobile Odin app, I looked on the market but there is only the pro version...

The safe kernel is included in the pa rom, cm9 kernel. So long as you flash it from cwm in gb you're fine it installs it automatically.
Think mobile Odin is only a paid for app... well worth it though. Check the forum, chainfire usually releases free versions to xda community.

If you asked me. I like the stock firmware not cm9 paranoid. Because you will lose your S-Memo, S-Note and S-Planner and also your myfiles and also the MHL. All of this features are important for me. Paranoid is cool firmware but you will loose this apps...

Update rom

My first ROM on my N7 is paranoid android of course. I have the build from September 9 and the latest is now available (goomanager informs me). After I down load this zip, all I have to do is flash this new file in order to be up to date?

All you have to do is reboot into recovery, wipe cache, wipe dalvik cache, flash the ROM, flash gapps, then reboot. Always wipe caches and re-flash gapps when you flash an update to a ROM.
Sent from my Paranoid Nexus 7
So if I'm understanding you correctly, after I wipe the caches... reinstall the rom and then put the latest version of gapps? (Just like you did to get the rom working in the first place?)

Yes. I don't know if you did this before you installed paranoid android, but it's a good idea to do do a full wipe/factory reset when you switch ROMs.
Once you're on a particular ROM, you only need to wipe caches before you flash the update and gapps.
Sorry if that was confusing

How to upgrade Android version when on custom ROM

So all right, I thought that when a newer version of Android came out and I am for example on CM10.1, I can update the android version and ROM by flashing a new bootloader and baseband, then flash the ROM and Gapps you want.
But today I read about someone who didn't accomplish to install a 4.2.2 ROM when he was on 4.2.1 so he installed factory image.
Can someone now please tell me what you need to do, so I am prepared when KLP arrives.
Thanks in advance!

Best advice I can give you is to learn fastboot. You can download images from Google once released and manually flash each thing that you want to update. You just unzip the files and fastboot flash them to your phone.

I think I am misunderstood.
I meant how to upgrade android version if going from a custom rom to another custom rom.
So for example CM10.1 Android 4.2.2 and going to Xenon HD Android 5.0
Thats possible right?

Most developers list instruction on how to install from different custom roms in the install method if they differ (example post#2 in http://forum.xda-developers.com/showthread.php?t=2075444). If not, you could post in the thread of the custom rom to see if there are any special steps for that rom. I would advise reading through the first few posts of the custom rom to make double sure they didn't explain how to first.

Why do you prefer that even of you install the same file? But the answer on my question is that I can install a 5.0 ROM if I just flash the new bootloader and baseband?
Thank you for helping me!
Yes, as I answered that earlier
As for why I prefer fastboot - I always like to do everything manually. I then know I'VE done things right as an updater-script in a CWM ZIP file could be wrong/corrupt. It's a safety thing. Plus, once it's done it's done so I wouldn't have to do it again unless I wanted to downgrade Android to 4.x

But with CWM you also have to flash once I think? Because you dont flash it on a ROM, but before a ROM so the baseband and bootloader will last untill you install another I think?

Fastboot flashing is permanent - once flashed you don't have to do it again. A CWM ZIP can do the same but I, personally, DO NOT LIKE DOING IT THAT WAY. I don't know what else you want me to say?
Do what YOU want to do

Yeah but CM11 (or whatever it may be called) wont be ready as yes as Android 5.0 comes out, and I may use the stock ROM the first day it comes out, which I will flash in CWM so I wanted to know if I needed to do something else.

Stock rom rooted issues

Hey guys I have recently rooted my Nexus 4 and left the stock rom on it. Now a few days later I am experiencing issues mainly with apps that change settings, like juicedefender or a cpu speed app.
I have done some research and according to juicedefender error log it shows I need to have busybox or I should have CyanogenMod.
Ok i hav 3 questions
1. Will installing busy box cause me to lose any data?
2. I know installing CyanogenMod ROM will clear all my data is there a way for me to backup need for speed and bad piggies?
3. Is there a way for me to keep my stock rom and fix these problems?
Sent from my Nexus 4 using xda app-developers app
Since you're rooted all you need to do for backups is download Titanium Backup and use that to keep all of your data.

You will probably want to start with a stable release before jumping into a nightly. Nightly build aren't really known for stability.

To update cm all you need to do is download new rom, boot to recovery, flash rom and gapps, wipe cache, reboot. Of course this only applies if the rom base hasn't changed, which is infrequent.

If you are going to flash cm for the first time a wipe is required. Usually wipes aren't required when flashing a newer version of a Rom.
But will it wipe data automatically? No. Wiping data is an option you have to confirm in recovery.
Is that what you are asking?
