I wanted to root for a while, just looking for a rom that looks and feels stock, but has better battery and all..
well I followed
watch?v=-hPSrzRqtX4&feature=player_detailpage (cannot post link as I'm new)
and successfully got to supra rom.. well I don't like the vanilla 5 screen non sense homescreen, though I do like the crt visuals lol...
Anyways, I can't even use my wifi, it just says error, and I NEED wifi, I use it at home non-stop as I have horrible service.
Well I tried to switch to viperRom - I did the reset in bootloader, then full wipe, then cache and all that..
well, once I installed the viperRom .zip, I started my phone and its just the same as before... I can't switch roms! I know this is prolly some nooby thing I don't understand but I've been searching all night and just want to get everything working and need to sleep haha
any help GREATLY APPRECIATED
What do you mean about not being able to switch roms?

I figured out that I was trying to flash to viperRom using only the update
I'm now on viper, with stock kernel and still cannot get wifi to work, any ideas? Any searching turns up kernel issues, and to revert to stock.. well I'm on stock kernel

unless you're having hardware wifi issues, which the best way to determine would be through running a stock rom and stock kernel, my guess is you have a kernel and rom mismatch issue.
the way htc has their kernels compiled includes two things: kernel and modules.
the modules include a wifi module.
if you flash a kernel and then load a rom, chances are the rom might overwrite either the kernel, the kernel modules, or both.
the best way to avoid this scenario is to flash the rom first and then flash the kernel. the kernel flash will load the kernel itself and its modules. i.e. if you're on a rom you want to stay with now, flash the kernel again and then wifi should work.
hope that helps!
Thank you, o figured this out myself, but you were right lol I was using 2.3.3 roms on 2.3.4

Just moved from iPhone to i777, wanted to get ICS, but eneded up bricking my first phone by installing something meant for i9000. At that time I didn’t know Galaxy S2 has variants, just searched for S2 and got burned. My fault…..should have understood better.
I want to do it right this time so I have been reading about i777, ROMs, kernels, CWM.
I want to put SHOStock or CM9 ROM.
I know where these ROMs are and how to flash them using CWM.
But that’s where my confusion starts, that there are just too many sources and options and I don’t know which one is right.
So please advise.
How do I root?
Using this? It has multiple options
http://forum.xda-developers.com/showthread.php?p=18576627#post18576627
or this ?

Which kernel to use
The one mentioned in SHOStock thread #3 post the Cherry Picker Kernel for i777 or Entorpy? Siayh
How do I get CWM on these, isn’t recovery part of the kernel or do I flash It separately or may be use ROM Manager, once rooted.
Modem? What does it do? Is it for phone or wi-fi and how do I know which one to use.
My phone’s data

Here's what you need to do:
1. Use Odin to flash stock UCKH7 with Root, available here. Be aware that doing this will require a full wipe, so do what you can to back up your sms/mms/contacts and other data. READ EVERY STEP CAREFULLY. Do not flash a kernel with Odin.
2. Now that you have root access, download Mobile Odin from the Play Store. Use it to flash either Entropy's DD or Siyah. This will install CWM Recovery.
3. Boot into CWM Recovery and make a nandroid backup.
4. Use CWM to flash SHOStock or CM9.
First of all thanks for responding.......
Is there a relation between which ROM will work with which Kernel, I may be wrong but I got the impression, depending on which ROM you are putting, you should have a kernel that supports it.
Also it seems like, ShoStock has its own variation of entropy, named cherry picker.
Thanks.......

Sometimes there is, but it seems like most of the ICS kernels are interchangeable. Just try out each kernel for a few days...once you have CWM, switching kernels is no big deal. When switching kernels, though, it's always wise to flash jivy's Kernel Cleaning Script just before flashing a new kernel.
Can you use CWM to flash kernels as well ? I thought they always have to be done using ODIN.
May be I underestimated CWM, I thought it was for ROMs and zips only.

u can use mobile odin or cwm but its just a matter of preference you just had to use mobile odin at first to acquire a cwm enabled kernel but pretty much you can flash everything in cwm as long as its specified to be cwm flashable zip kernels roms and modems and such
edit: the free mobile odin only lets you flash kernels btw its the premium version that lets you do everything without going to recovery
hope to help

You don't seem to have a firm grasp on all this. Maybe you should do some more reading before going further...
Anyway, here's a brief explanation:
A kernel is the underlying core of the operating system; it is how the OS interacts with the hardware.
A rom (the proper term is actually firmware, but nobody uses it) is basically the whole user interface; it's the part of the OS you see. When you flash a rom, you're flashing everything, including a kernel.
Like I said before, you never want to flash a custom kernel using Odin. Doing so will trip the phone's flash counter, and this will show up if you ever have to take the phone in for warranty stuff.
The reason it's ok to use Odin to flash the stock with root package is that it comes with the stock kernel, not a custom one. Basically, once you're rooted, you shouldn't touch Odin again unless its to recover from a brick. Basically everything else can be done in CWM.
Yes I am still reading & trying to get a grip on it.
So first I will root it, then flash kernel using Mobil Odin
Then get in CWM mode ad flash ROM, which will come with the kernel i.e. cherrypicker kernel and modem I need.
Yes one part I have understood very well is that use CWM as much as one can to avoid committing mistakes by flashing something that doesn't belong.
Sorry for asking so many qs., I wish I could understand this faster.....
Thanks again........

Yeah no problem. I would suggest that you wait a while before doing this. Read through all the stickies and guides to can find, and get more familiar with everything. Then after a couple days, go for it.

You don't need any more of a guide than that. Don't worry about breaking wifi, that isn't a problem on any of the popular roms.
If you want a Samsung based ICS rom that works really well, I suggest ShoStock2. If you want an AOSP based rom, most people suggest AOKP. I haven't tried it personally.

You're wifi won't go away in the first place.
I figured this will be asked before long. I read some of the long thread on upping to stock 4.0.3 but didn't see any definitive answers.
Here is my situation. I've had my phone for six months on stock 2.3.6 using Entropy's rooted package. Honestly, right now I don't want to run any custom ROMs. I may run CM9 once a final version comes out, but I don't want to bother with the nightly builds. I haven't had any problems with the stock firmware.
So, the other day I lost my phone. Fortunately I had an upgrade, so I got another SGS2. I again loaded Entropy's rooted package, and then upgraded to stock ICS from there. Everything went fine with the upgrade, but I lost root (not surprised). Is there any way currently to root 4.0.3 and keep the stock kernel and ROM?
I mainly want root to enable wifi tethering, which I tend to use often.
At this time, I don't know of any way to root the stock UCLE5 without replacing the kernel.

Ok, thanks for that. Apparently FoxFi enables wifi tethering without root. I'm sure someone will have a rooted package soon. I look forward to a final CM9 release.

You could go back to entropy's rooted GB package and then do as mattdm suggests...havent tried it though.
I have rooted stock LE5 with LE5 kernel but it does involve flashing the SGH-I777CWM recovery kernel, temporarily flashing a 3.x.x kernel to get root injected to the LE5 system, then some file manipulation/repackaging to include the LE5 zimage and flash again, and then pushing the recovery .img (or use rom manager app) to make it all happen...not a simple process if you've never done it but in my case it was worth it.

hey it's not that much really..and if you've already flashed LE5 and set it up, going back to stock takes a few steps in and of itself. This is just a well thought out, calculated, then executed process not some "mess" as you refer to. So...if you're bold enough to use more than three brain cells...including the ones that tell you to show some couth when you post! ...
then by all means use them and try your own method to root...as I have.

You have to have a rooted phone to flash kernels. The Cubed kernel is a modified kernel for root users that gives you the ability to overclock your phone, better battery life and such. It is not the one that came with the DNA, the DNA is the stock kernel from the factory. Don't go by the numbers you see because they are 2 totally different kernels for totally different reasons...

This is the stock kernel but just modified to be able to write to the system while booted. It basically is the stock kernel and will work exactly like the stock kernel does. To switch kernels, just do what you did before when you installed the kernel you're on now. Just make sure you flash the correct module zip in recovery after you flash it.

So starting yesterday my droid dna has been stuck in a boot loop. I just bought it about 5 days ago.
It was rooted and running supercharged HTC sense rom and stock kernal.
I tried everything I could find online.
I relocked bootloader and restored rom using the RUU exe that everyone links, I re-unlocked installed the rom again to see if that would work and it allowed maybe 2 full boots out of 100+ tries occasionally it booted up and had several crashes on the supercharged that included the custom AC!D sound mod adn the UI would lock up if I tried to make or answer a call. I tried re-restoring with the RUU. all fastboot commands worked fine with no error on restoring the bootloader and recovery etc.
NOTHING is working. Please help for the love of my brand new droid dna which has already boot looped...
Have you tried just restoring from your backup? The one you made before flashing the rom
And just curious. Did you dirty flash it? What recovery are you using?

There's a discussion in that thread about the developer including the kernel in the rom, doing that won't flash the kernel. It doesn't look like the instructions were updated to reflect that. Try Supercharged Hatka, made by the same developer along with Mustafa.
I managed to get it to boot up as stock with a 2nd relocking using fastboot oem lock and the RUU.exe. Haven't had any issues yet. I will see if anything goes wrong. Made a few calls and restored off gmail account.
Now that you got it running don't use that Rom this time, try Supercharged Hatka or Viper.

Maybe. There are so many boot.img files floating around things get mixed up and sometimes you forget what kernel you're running until you look at the About phone menu. It would be nice if they could be named appropriately.

Yours looks stock. Covxx said he put DSBs kernel in the rom but it has to be flashed separately to apply it, therefore DSBs kernel is not flashed and you remain on the stock kernel. Dsb has his name in the kernel version when you look at About Phone.
