Hi,
I had a few questions about kernels...hope someone can help me in answering these...
I am thinking of trying out the Netarchy kernel on my Nexus S, but i was just wondering is there anywhere I can download the stock kernel (so that if anything does go wrong i dont have to do a full nandroid restore?)
Also, when installing a new kernel does that wipe data (of course I will make a backup etc before installing it, but should all my settings and apps etc remain intact normally?)
what impact does an OTA update have if i am running a non stock kernel? so say i am using Netarchy's kernel, and google releases a new OTA update...will i still be able to install the update? If i do, will it revert to stock kernel?
Thanks in advance,

I'm not aware of anywhere that the stock kernel is available for download so doing a NANDroid backup is really your best option. If you have anything that deviates from stock (kernel, rom, theme, even just deleted stock apps) it will prevent you from being able to successfully update from an OTA.
You can find a lot of information about all the available kernels here just scroll down to the third post and you'll find the info.
Finally, just as a note of personal opinion, getting OTA updates is a little overrated. If you run a custom ROM, the OTAs will be included in those ROMs eventually so you won't have to worry about restoring a stock ROM just to get the updates.

Thanks for the quick answer. I had read that post before (it was actually how i came to discover kernels ). The reason why I was asking about the OTA is because I actually use the stock ROM but was just thinking about trying out the Netarchy kernel just to see what its all about. Hence if there is an OTA update, and i am running a different kernel to the stock, is the only way for me to incorporate the update by flashing the new stock rom and then reinstall the netarchy kernel?
Also, if i install it, do you know if it wipes data/apps?
Thanks

I apologize as I forgot to mention that part of your question, I'm sick with the flu and a little out of it on some cold medications lol. You only lose data and apps when flashing if you wipe the /data partition in mounts and storage and this is not required nor is it recommended when flashing a kernel. Sorry for answering out of order, but I thought I should clear that up first. As to the other question, you have it correct; you would need to flash the new update ROM and then flashing a new kernel.
I should also note that whenever you install a new ROM, you will need to reflash a custom kernel. This is because the vast majority of ROMs released include a kernel and when you flash them it will overwrite whatever kernel you currently have.
Finally, if you have any other questions you can always feel free to post them on that thread. I'm the one who wrote it and I check it often to try and answer questions as best and as quickly as I can. Happy flashing!
Are you using a custom ROM? Flashing CM7 has the stock kernel. There are probably other ones out there that includes stock kernel with them such as OTA.
Hi, I'm new to flashing ROM's and wanted to give this a try, but I had a few questions (I searched and read the wiki, but I didn't see these specific questions):
I have the Samsung Galaxy S2 Skyrocket on ATT. I'm rooted on Stock GB 2.3.6
1. I wanted to try flashing this ROM([ROM][CyanogenMod 9 (unofficial)][TeamChopsticks][Alpha 1 - 4/26]), Can I come from gingerbread if I follow the instructions in post 1? Or do I need to have an ICS leak installed first?
2. I assume I can revert back to my rooted-stock ROM by using CWM with my current restore point?
3. If I restore the backup from step-2, does it restore the original radio (the UCLA3 radio)? Or am I stuck with the new one? Any disadvantes to just leaving the new one installed?
4. When flashing the new radio, is it just like flashing a ROM in CWM?
5. How would I get all my apps back on the custom ROM? (I know the contacts are linked to the google cloud) I have titanium backup pro installed now, but I read something about not restoring the apps across different ROMs?
6. If I decide to go back to my stock ROM after looking at a few custom ROMs, would I be able to get the ATT OTA updates? (I know I'd need to un-root and un-freeze all the bloatware, but I assume installing the custom ROM's would trigger the flash counter?)
7. I keep hearing about the "yellow triangle" when the flash counter is triggered. Does it only happen at boot and go away after that? Or is it always there?
Thanks in advance!

1) if you're a newb I wouldn't recommend flashing alpha versions of anything
2)You can revert back
3)No, flash a ginger radio before restoring
4)Yes, wipe cache/dalvik cache
5)You can restore apps accross the same OS, but I never do
6)Yes, if you're on official software. It wont trigger unless you flash with odin or sometimes a custom kernel like cm will trigger it. No big deal, we have a counter reset.
7)only at boot, we have counter reset, so no worries
Wow, that was a quick reply! Thanks.
Sorry if I'm dense, I just wanted to clarify two things before proceeding.
Re 1: I also saw another ROM I wanted to try, I guess I'll do that one ([ROM]SKY ICS--- 4.2D-9). Thanks for the heads up.
Re 3: From your response, am I correct to understand I can't use an ICS radio with GB? (it just wont work? or there's no advantage to keeping it?)
Re 5: Same OS meaning inside GB based ROMs or ICS based ROMs? If I go from stock GB to custom ICS, I need to re-download each app individually?

1) very good choice, I run it and it is outstanding.
3)they will have a RIL mismatch. You can use them by deleting the system folder out of it, but I would just use the la3 radio and flash that before the rom. After a full wipe, of course.
5)Right, it ensures everything will be clean and run right.
Thanks to everyone on this board - last night I rooted my device, unlocked the bootloader, installed CWM, backed up my stock ROM, and installed CleanROM 3 Lite (which is excellent btw!). My first time doing this, so it was very helpful having all the FAQs and instructions.
On to my question: now that I am running a custom ROM, what happens if there is a newer ROM released? Do I simply re-flash that specific ROM, the same way I installed CleanROM 3 Lite?
If so, it sounds like I lose all my apps/settings... is there some way to keep that across ROMs?
Thanks!

yes. And unless the developer says not to, you can USUALLY skip wiping /data when upgrading to the newer version of that developer's ROM.
As for keeping apps, get Titanium Backup. worth paying for.
If you are going to upgrade to the next cleanrom release, you should be fine...just flash the next release and your apps and info should be fine.
Should you choose to switch to another rom, it is typically recommended that you wipe the phone first, in which case you will lose your apps and info, so make sure everything is backed up.
The problem with keeping apps and settings across different roms is that there can be "compatibility" problems.
That makes a lot of sense, thank you guys. I thought that flashing a ROM automatically wiped everything - but I realize now that's not the case.
I will check out Titanium Backup as well.

Actually, sometimes it does. Recently some Devs are adding Aroma Installer to their ROMS. It only works on touch recoveries (I believe). I am using TWRP and it works great. It backs up your info, lets you choose different options you want for your rom (modifications, different choice of apps, look and feel, sense or senseless, etc), flashes the rom, then restores your info automatically.
Is there a way to update phone without losing root.. Galaxy s3 to (sprint). Running wicked sensations v2.1. Currently got lj7. :good: Thank you and have a great day.
Not too sure but I think the safest way is to go back to stock rom & unroot, then update youre phone & then root again, the rooting process only takes about 5-10mins anyway. Cant really see why you would wanna go back to stock rom after being rooted & running a modded rom? But hey hope this helps & if so press the thanks button :thumbup:

I dont want to go back to stock.. Just wanted the update.. There is no way i would ever go back to stock. I love the rom i am currently running.. Thank you for your insight though.. I know freeza has a couple of updates up.. Just don't know which one to do. The odexed or the deoxed one..
If youre just asking about updating youre custom rom.... just make a backup via youre recovery mode, wipe cache, wipe dev cache, wipe/factory reset, then flash the rom, test it & if you are not happy, reapply youre backup? :thumbup:

Flashing
No my custom rom rom is up to date with the newest release. Was referring to the kernel or whatever it is that is being pushed by samsung. When it switched to jellybean 4.1 it was lj7. Which is what i have.. Since then it has updated to 4.1.2 with mb6 and just recently mb1. The newest contains the multi view addon.. This is through google as well.. Anyway it is the samsung firmware, not my custom rom firmware.
I tried to flash the latest stock rom for an SM-T111 device using Odin
the device is on the latest stock rom already, but had problems with apps and wifi connection stability, after flashing the problems were gone but the user data is still there (all the apps, accounts, settings and even homescreen icons and gadgets)
When flashing I expected a clean and fresh rom from the start, but that didn't happen and the only difference is that the problems were gone.
Is this normal for this device or for Samsung in general?, or did I do something wrong?, Am I missing something here?, and what if I want to downgrade to an older stock rom? what should I do to have a clean and fresh start?
Thanks
