Hey folks. Being the noob I am, I posted on here a few days ago asking how to go about rooting my phone. Well, thanks to some friendly advice (and DoomLord's easy rooting toolkit) I have been able to clear that hurdle. Now that my phone is rooted, I would really like to be able to take advantage of all that has to offer (overclocking, underclocking, better battery life, etc.). From what I've read on the interweb, I need to flash a custom kernel to do that. Before I jump into this task, I have a few questions:
1) Do I need to flash a custom rom to use a custom kernel?
2) I am on a small, regional cdma carrier. Would changing my kernel affect my baseband, causing me to lose data coverage, or even lose cell service entirely?
3) will doing these things cause me to lose all my apps?
Custom kernel are not available to flash, being that the boooader is locked; however, the stock kernel supports overclocking, undervolting, etc. so you need only download an overclocking app.

So just for the safety's sake, the stock kernel:
2.6.32.9-geadffa3

Will work with an app like setCPU for over/underclocking, undervolting, etc?
Also, could you tell me some good clocking settings for the droid/milestone x?
The stock kernel allows you to overclock using those apps. However, I think there have been some issues trying to overclock the X if you are running an ICS custom rom. I think I read that QuickClock was working, but I'm not positive.
As for OC settings, each phone will act a little differently. You just have to test them out and watch to make sure your phone continues to be stable. You can start out testing at 1080 or 1100 and take it from there.

Hey gang.
I'm waiting on my DZ arriving, looks like tomorrow now, and I have tried many roms with my current phone but I always end up going back to sense as I like it. The more I read about the DZ and the different roms, the more I'm thinking that I might not bother with roms and keep the stock.
Battery life is important to me however and the saving grace on my current phone has been setcpu. Obviously I'd need to root the DZ it to use it. I'm not too bothered with overclocking it really, however I do like to underclock it when the screen is off etc.
My question is, I know that you can only overclock on some kernels/roms that support it. But is it the same case with underclocking it? Or should I be able to underclock fine on stock?
Of course u need root. But u can use the stock rom with root than flash it with a kernel that u can under/overclock.

Can you recommend a kernel that will work ok with stock then?
A custom kernel may have different or more underclock stepping choices, but the stock kernel should underclock just fine once you are rooted.
Are DZ's shipping with Gingerbread nowadays? Kernel is dependent on Sense versus AOSP, and also Froyo versus Gingerbread. Godspeed kernel worked fine when I was on the DZ stock Froyo ROM.

Just use Search type in "Kernel" than u get all kernel Threads. I tried many kernels but now im using ILWT Kernel CM7 1.7.0 =)

It hasn't arrived yet, it's advertised as Froyo but we'll find out in the next few days.
As long as the stock kernel underclocks fine, as I said, I don't care about overclocking. If it doesn't work right then I'll get to custom romming it.
Just loaded rooted stock 3.2 and would like to overclock. I'm having problems trying to use SetCPU though. How do I raise the clock? I don't get a menu option on the notification bar.
If you're rooted with stock 3.2, you will need to flash a kernel that allows overclocking at different frequencies and voltages. All the cpu apps do not physically do the overclock, they only control it.
Oh, that's a shame. Custom roms always seem to have a bug or two that spoil the whole experience
I guess I was just confused because I have a DROIDX that is stock rooted and can be overclocked.
EDIT: Nevermind, noob in training here; confusing ROM and kernel. Will go flash Thors kernel now.
Okay, so I read many new threads daily regarding how to root, about custom ROMs and everything so I thought I would just start this thread where we all could share what all we know. Something like FAQs for SGN. Without further delay, let's start.
1. What is rooting? Is it dangerous?
A. “Rooting” your device means obtaining “superuser” rights and permissions to your Android phone. When rooted, the user can run various apps that require root permissions to run and also, it allows the user to install custom ROMs or to flash various kernels, overclocking or underclocking the device etc.
Rooting is NOT dangerous. There are guides available here on XDA on how to root and they are pretty easy, straightforward and risk free.
The only disadvantage of rooting is that it voids your warranty but you can easily unroot your phone to get the warranty back.
2. How to root?
A. Pretty easy! Dr Ketan has created this very very simple guide on how to root. You can find it here.
http://forum.xda-developers.com/showthread.php?t=1329360
Don't forget to thank him!
Easiest method in my opinion is to flash a pre rooted stock ROM through PC Odin.
3. How do I unroot?
It's mentioned in the guide above.
4. What is recovery?
A. Recovery refers to the dedicated, bootable partition that has the recovery console installed. A combination of key presses will boot your phone to recovery, where you can find tools to help repair (recover) your installation as well as install official OS updates. Now because Android is open and has the recovery source code available, building a customized version with more and different options is relatively easy as well.
5. ClockWorkMod Recovery??? How do I install it?
A. CWM, as it is generally called, is a custom recovery for Android. It offers many more options than those offered by the stock recovery and it's generally used to flash custom ROMs.
Installing CWM on your phone is dead simple. Again, thanks to Dr Ketan for his awesome guide. Here you go.
http://forum.xda-developers.com/showthread.php?t=1329360
6. What is a custom ROM?
A. A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc - everything you need to operate the device, except it's customized by someone in some way.
Since Android is open source, developers are free to pick up the stock ROMs and modify them the way they like. As simple as that!
7. So how do I decide which is the best custom ROM?
A. There in no best custom ROM as such. Different ROMs have different advantages and disadvantages. Some give you incredible speed, some give you battery, some are better looking and so on. You have to decide what works best for you.
8. Do I really need to install a custom ROM or is stock good enough?
A. Ask yourself! Personally, I feel stock is crap. Also, there are many ROMs that offer stock experience whilst removing everything that makes the stock ROM crap.
9. Can I brick my phone while installing custom ROMs?
A. Yes and no. While it's pretty hard to actually brick a phone, it's possible. Use the CORRECT files and follow the steps as mentioned by the developer. But, as I said, it's highly unlikely that you'll end up with a bricked phone.
10. Okay, so I am ready to install a custom ROM. I know the risks and everything. How do I install it?
A. First of all, you need your phone to be rooted and you also need to have a recovery, like CWM. Now, different ROMs have difference installation procedures so I advice you to just read their respective threads thoroughly, know more about the ROM, decide if it's good enough and follow what the developer says. Use the CORRECT files.
Also, whatever you do, make sure you make backups of your current system through CWM. If ever something goes wrong, these backups will help you restore to your previous system.
Go on, it should all be easy!
Edit: Do not make Nandroid backups in CWM when on LPY, LPF, i9220 repack or other unsafe kernels. There's a very high risk of bricking your phone. Read the stickies!
11. What is Overclocking/Underclocking?
A. Simply put, overclocking is the process of increasing the clock frequency of your phone's processor. Underclocking is decreasing the frequency. It basically makes the processor run faster/slower according to what you set it for.
12. Risks of OC?
A.
Overclocking reduces the lifespan of the hardware of your phone.
It's possible to incurr permanent damage to the phone's compenets by OC.
Overclocking voids the warranty of your phone, but rooting has already done that!
13. Should I overclock?
A. Personally I think there is no use of OC except to fry off your processor and get higher quadrant score (which doesn't mean anything really!). With all these phones with fast processors, OC is less necessary.
14. How to overclock?
A. You need a kernel that supports overclocking. Like franco's kernel supports OC I think. Then you need an application (like SetCPU, No Frills CPU etc) to OC your device. Sometimes, OC options are built into a custom ROM as well.
15. I've had enough of rooting and custom ROMs. I need to go back. What do I do?
A. The easiest way to go back to stock ROM is to just simply flash any of the unrooted stock ROMs through PC Odin. As simple as that. Refer to Dr Ketan's guide for this.
16. What is an unsafe kernel?
A. Most stock ICS kernels are affected by the emmc bug, popularly known as the brick bug. The official CM9 kernels and some new other kernels are although free from this.
17. F***! I am on an unsafe kernel. What to do?
A. You should actually firstly know what not to do and than what to do. DO NOT wipe data in CWM, DO NOT factory reset your phone through either recovery or the Settings Menu and DO NOT delete big files from your internal or maybe even external memory. This heavy R/W operations triggers the brick bug and most often leaves the phone as useful as a paperweight.
Now, what should you be doing? If you're not gonna do any of the above, you're most probably as safe as those on a safe kernel. If you wanna get rid of this emmc bug altogether, you have to firstly go back to GB, use PC Odin method as stated above and then flash any of the new ROMs with safe kernels, read the dev section.
18. I wiped my data previously on an unsafe kernel and now my phone wouldn't boot up. I tried going back to stock GB with the PC Odin method but I'm stuck at "factoryfys.img". OMG! I can't even breathe now.. HELP!!!!
A. Superbrick. Yes, that's the word. Unfortunately, your phone is now bricked and only Samsung could help you now. Or if you're comfortable you can read and watch the DIY guides to replace the affected parts (motherboard).
So, this is all what I could think of at the moment. If you have any more Q&A that could help others, do add them!
Hope this helps..
Good one bro! It should help most of the folks out there! And quench many repeated questions
Thanks man!

I am a burnt newbie. I tried to install a ROM from RootGalaxyNote that seemed perfect. A week later, after getting it back from MobileTechVideo and a full JTAG repair, I laid back on everything. Then I ran across Philz. Love what this guy does. Rooted the kernel MobileTech installed, and installed the Rom I'm using now, SweetROM V2.5. Hope this posts as I am 7 away from being able to talk to the"Big Boys".
Choosing a Kernal for your phone
I looked through PhilZ-cwm6 - Safe Stock Based Kernel but couldn't find anything that matches my kernal version. I honestly do not know where to ask so I hope you don't mind me asking you for your help. What kernal version do I download if this is my phone details:
Model number:

Android version:
4.1.2
Baseband version:
N7000WELSA
Kernel version:

Hi, i'm a little bit scared about modifying it. Is there a real big difference in performance between the stock rom and a custom with a kernel at stock frequencies? And i've seen a lot of methods about unlocking/rooting it, but i am scared if i brick it... Is there a 100% safe method to unlock and root it? And i've heard about a problem with the buggy stock recovery, will i have this problem if i flash cwm?
Sorry for the huge number of questions and for my bad english
Sent from my Nexus 7 using xda app-developers app
Personally I found that there is not a great deal of difference between stock ROM and many of the custom ROMs out there. For me it is more to do with having the freedom to get tore into the tablet.
There is never a 100% guarantee that yo won't mess up when rooting and installing custom software, however the vast majority of users on here have managed to do it safely with the tools available.
If you are going down the path of rooting and customs, may I suggest you give the team EOS ROM a try coupled with Franco kernel. They work together like a dream. Also paranoid android ROM for something different . Though I found it to be a little slow for my liking.
Finally clemsyns elite kernel if you want crazy performance, but it does eat the battery
Sent from my Nexus 7 using Tapatalk 2
Rooting is quite painless and reasonably safe if you follow the directions closely. The one click rooting methods, elsewhere in this forum...work well.
Myself, I prefer the stock rom. The custom roms might offer better performance, but can be buggy at times. although. I do switch back and forth to try them out. Remember, these roms
are all works in progress, so do not be surprised if something does not work the way you think
it should.
Thanks for the answers. I'm thinking about only rooting it. Will i receive the ota for a new update?
Sent from my Nexus 7 using xda app-developers app
As long as you keep the stock recovery you can keep doing ota updates
Sent from my HTC One X using xda app-developers app
In my experience, OTA never worked to well.. but there are ways around it, for example... backing up your apps, then load a fresh updated factory image. then just restore your apps..
Titanium backup is one such app, but there are others .
So far no matter what I try I cant brick it oh I can get it stuck but theres always a way to fix it. And like some others here I have tried I believe every ROM out there. Not one really stands out "different" for ME then any other. Nexus root toolkit is by far the easiest to use for me. If your into battery life so far Stock wins hands down.
Unlocking and rooting the Nexus is really simple and pretty much foolproof. I'll admit there isn't that much of a difference between stock and custom ROMs because the N7 with JB is already a beast. I just like custom ROMs because you have the ability to make it faster if you want to (I have my CPU over clocked by 500 MHz and my GPU over clocked by 300 MHz thanks to clemsyn's elite kernel) the only reasons why I wanted to put a custom ROM on this was because I missed the 3 in 1 shutdown menu and the ability to remove the notification shae toggles, other than that I don't mess with much because JB is already buttery smooth. Gone are the days when you have to root, OC and install custom ROMs just to get good performance out of your device like I had to do with the OG droid.
I would definitely at least root the device for the time being. Aside from some customization options in a few custom ROMs I actually really enjoy stock on my N7... I would also take a look at ... http://forum.xda-developers.com/showthread.php?t=1905961 once you have it all ready to go... I found it made an improvement to my Wifi and GPS by a fair bit, no custom rom needed.
Hi all! I have my Nexus 4 unlocked, rooted, and running cyanogenmod 10.1, with TWRP as my recovery image.
I recently stumbled upon this custom kernel
https://plus.google.com/107979589566958860409/posts/9VtBVHP67Hg
It helps with the saturation problems with the Nexus 4, and I highly recommend it. I am, however, really trying to squeeze as much battery life as possible out of this device, and I am very interested in flashing the franco kernel, but I don't want to loose my improved screen colors. Is there any way to get the combined features of the franco kernel and this saturation kernel? Also I have heard about the faux kernel that lets you mess with the screen settings (gamma, etc) yourself, and apparently that one lets you overclock, though I'm not interested in overclocking. The franco kernel undervolts your processor, and it makes your processor only use 2 cores on the home screen, which apparently saves alot of battery life and that, to me, makes alot of sense.
Anyway, I was wondering if there was some way I could flash both of these kernels, or combine their features, or maybe there is a kernel with both of these benefits?
Thanks!
P.S. My friend got a nexus 4 and I compared my screen to his, and mine definitely looked significantly better.
Flash fauxes kernel

I've been using franco and am pretty pleased with it so far (only had the phone for 6 days), which I also used to use on my Galaxy Nexus.
The gamma tuning really makes the screen look a whole better too.
kernel risks
Hey Guys, thought I would ask a question related to kernels in this thread rather than start a new thread.
I'm not sure why I'm worried about flashing a kernel but I am. Probably because my phone is so new.
My question.......In reality, flashing a kernel probably presents the same risk as flashing a new rom, correct? I've just read some harrowing threads and do not want to even come close to bricking my device.
Thanks for any input!

In order to flash a kernel, put it on your device, reboot into recovery, wipe your dalvik cache and your cache. Then install the zip and reboot. I did this for the saturation kernel, and just now for the franco kernel ad it worked out great. I don't know what might cause people's devices to brick, but in theory that shoudnt happen.
For the record I installed the franco kernel and bought the franco app. So far it seems good.

I've been flashing ROMs, kernels, etc, for 3 years and have yet to brick a device [knock on wood]. Just take your time and be sure of what you're doing and you should be fine.
