I have a quick question.
I flashed the franco kernel using franco's app, and also made a backup of my stock kernel using the same app before flashing.
If i decide to revert back to stock kernel, all i'll have to do is flash the stock kernel backup, right? It won't mess anything up?

I'm actually getting ready to flash Franco's Rom now, I figured since the kernel is in the boot image, and if I make a backup with TWRP (doing full since I want to keep my latest changes). Then if I don't like it I can just restore only the boot image portion of it assuming everything else remains the same.

I'm thinking of flashing Trinity kernel on my Nexus 7. If I have troubles after flashing the Trinity kernel and want to revert back to my present kernel do I restore a nandroid backup or is there something else I have to do to get present kernel back? Am currently running CM 10.1 jb 4.2.1 on my Nexus 7. Any input would be greatly appreciated. Thanks.
Just do a dirty flash (flash CM10.1 again without factory reset, just wipe cache and dalvik). Your kernel will be overwritten.

yup, thats the easiest way. but you dont have to wipe anything, not even dalvik or cache. you can always extract the boot.img from the cm rom and flash it via fastboot too.
Thanks simms. I'm still trying to figure everything out just got my Nexus for Christmas.

Ive read that franco has a ramdisk of his own, how do I apply a new kernel without problems if I will try a different one (say motley kernel)?

Flashed Trinity kernel on my Nexus 7 and it is great. Am running CM 10.1 JB 4.2.1 latest nightly and so far everything is working awesome. Thanks for everyones input. Thanks to morfic for a wonderful kernel. Boom! Freak out now.
Hi Everyone,
I have stock rom with franco kernel. Yesterday I reverted back to stock kernel and noticed that it lags now when I wake it from the unlock screen. I did a factory reset, but the lag is still there. This was never there when I had it from the begining. Should I flash the factory image?? Can the backup stock kernel get corrupted?

Try _motley's reset kernel, it restores other files that may have been changed too

after using franco kernel, you have to reflash your rom then kernel. franco kernel hides tweaks inits ramdisk. flashing another kernel on top will not change this ramdisk, so you have to flash your rom first(no wiping anything).
As I stated above...can I just fastboot then flash the factory image??

absolutely. then youll need to reroot. its MUCH easier to flash a rooted stock(thats what im guessing you are using) rom though.

You can fastboot flash the OEM boot.img; I'm guessing you fastbooted Franco's kernel?
http://forum.xda-developers.com/attachment.php?attachmentid=&d=1361814949
Flash this reset kernel which has the INITFRAMS.
all will be ok.
You don't have to reflash the whole phone.

I suppose I can...however....I currently have a chromebook (ARM)...dunno if I can use fastboot with it. I wanted a solution I could do straight on my phone, like, flashing CWM recovery, then downloading the stock (rooted, CWM flashable) ROM...and flashing it.

Could you clarify this for me, If in the future I need to do it? So, after leaving franco kernel, i.e. If I'm using franco kernel and wanna go back to completely stock again; before flashing stock I'll need to re-flash the current rom that I'm using, to re-flash the rom's kernel and this way replace the ramdisk to the stock from rom? If I'm wrong, please correct me; you guys are awesome!

yes, kinda. reflashing your rom will replace francos ramdisk. all the other kernels use anykernel, so dont have ramdisk included. generally, its only after using franco kernel do you want to do this, the other kernels you can flash right over each other. anykernel kernels grab the available ramdisk. theres plenty of stock/aosp rooted roms here on xda, any of them should work for you.
So, my stock nandroid backup has failed me. I am on Slimbean right now and I like it, but I would like to flash back to stock until all the kinks are worked out. How can I get back to stock touchwiz? I'm not exactly sure what a deodexed ROM is, but it is my understanding that Wallet does not work on one so I would like to be on a ROM that allows wallet.

You could either use Odin to flash the stock rom and be back at square 1, unrooted. Or you could flash crawrj's odexed rooted rom, and Google wallet works on that. Just read up on disabling SEAndroid so you don't get the nag.

That is just what I was reading now. I'm probably going to flash that. I do understand it doesn't come with a kernal, so if I'm on Slimbean can I just wipe and flash the odexed rom over that kernal? If not, how do I get the stock kernal back to flash over?

Good point. Flash Shabbys custom kernel, it's linked in that same thread (crawjr's). So wipe, flash odexed rooted rom, flash kernel. You will need to freeze that SEAndroid app though, don't forget about that.

Alright, so I can flash both at the same time? Also, how do I freeze the app? Just disable it in the settings?

I used titanium backup to freeze it. You need the pro version to do that though
EDIT: Someone just informed me that the app is in the system/app directory, and is called KNOXAgent.apk. So I supposed you could try deleting/renaming that to disable it without using Titanium backup.

And yes, flash the rom and then kernel in the same recovery session. You currently have an aosp kernel, so I'd doubt it boots if you tried to boot before flashing the kernel.

I guess you don't need a backup, you can easily extract it from the stock rom and the flash it back

No need to backup before flashing to Franco Kernel? If so how i extract the stock one later if I'll need it?

You download the stock rom zip from Google's site where the images are stored. Then you extract the zip and as far as I know there's the stock boot.img inside. Then you can simply flash it

I want to try another kernel.
Can I then restore the stock one using nandroid, or will I have to flash the stock rom again?

I think it will restore the stock kernel as it gets the device into its previous state completely.
