[Q] Flashing kernals and roms questions

I have a kernel that i found that i want to flash. When you flash a kernel, does it replace a flashed ROM or do they combine?
Also, when you flash anything (ROM or kernel) does it replace the stock ROM or does it take a spot next to it? Can you make several spots so there can be more than one ROM? What is wiping out a ROM? If you leave a ROM, can you save your setting so when you go back you don't have to start over again? Can you back up contacts,messages, and apps from stock ROM and extract the data to the new ROM?
I AM CONFUSED

1. No, they "combine"
2. It replaces it when you flash
3. Yes, but its more complicated than just flashing multiple roms. There is an app but it doesn't support Sensation.
4. Wiping a ROM is just that, wiping your phone of the ROM along with all your app,data and anything else on the phone(SD card not effected).
5. Umm. I don't understand your question completely but yes flashing a new ROM over an old ROM will preserve your data but you can flash a different rom and expect it to work. For example ARHD-->ARHD(updated) is OK but ARHD --> Insertcoin wont work.
6. Yes, its called titanium backup. Look it up.

thanks. after reading this, I stumbled on radios. what are radios?

Radio is what gives your phone signal. which version works best for you will depend on your location and carrier so you will just have to experiment. its generally advised that you flash the latest recommended version stated on the rom your using

The only thing I'd add is that for:
o If you leave a ROM, can you save your setting so when you go back you don't have to start over again?
You can do a Nandroid backup from CWM recovery, it takes a snapshot of the ROM, Kernel, Data,.. You can then play with other ROMs. Then at a later date restore the Nandroid backup from CWM and you're back at the earlier ROM.
It's extremely important that when you play with ROMs you backup a working version. It saves a lot of swearing when you lose a nice working system unintentionally. It's happened a couple of times to me and it's a bugger.

[Q] how to update a rom?

i looked through the forum and didn't find this exact question so i'm sorry if it's been posted before.
basically what i'm wondering is if i have a ROM installed, let's just say one of the new ICS ones, and a new release of that ROM comes out, is there a way to upgrade to the newer version without having to install all my apps and stuff again through titanium backup? i hope that makes sense. in other words, is installing a new version of a ROM that you are already using going to be the same process as flashing a new ROM entirely? that could get annoying with newer versions of ICS seemingly coming out twice a week.
thanks in advance!

It's recommended to wipe and reflash, but I just flash over top and if there's problems I resort to wiping. Clear cache and dalvik and just flash over top, your apps will still be there. But if you do it this way, you should not report any problems

Probably could have used search to find this. But typically, unless the dev say to full wipe, when an update comes out for the rom you are using you can flash the update over the older version without a full wipe. You are still required to clear cache/dalvik to do this. If anything that was working before does not work anymore after you have flashed the update over the older version, then you should go back and do a full wipe and flash the new version. I personally always full wipe when flashing a newer version.

It all depends on the ROM and what is updated. Seriously you have to go by what the DEV says in his thread. Some you can update without wiping and some you have to wipe. Others will automatically wipe for you. Best advice is to read the DEV's thread. They should all give you this info. And if you looked over the first few posts of his thread you really wouldn't be asking this question here.

Some mods have the cache/dalvik wipe built in, so just make sure you read through the thread for whatever mod you're trying. Wiping it twice won't hurt, but just wastes a little time.

I know that we have different method for rom installation but do you have any idea about RunnyDrOiD
Thanks

really? man. I'll make this very simple for you.
1. put rom on root of sdcard
2. boot into recovery
3. wipe data, cache, dalvik cache
4. install from sdcard the zip file
5. reboot.
almost all ROMs except for the PD98IMG.zip stock ROMs are flashed with the above method. Not all ROMs require a full wipe (data, cache, dalvik cahce) when upgrading within the same ROM but it is recommended to do so to avoid any issues. If you're switching between different ROMs, it is required to do a full wipe. Search my good man.

Nexus S 4G Root issues?

I've been playing around with a Nexus S 4G that I have lying around and never used, and I've ran into a few problems, but you've all been helpful. I rooted all my old EVO 4G's without any problem, but the other day I rooted my NS4G using a one click/simple root and downloaded ClockWorkMod etc. But now for some reason It seems like I've almost lost my root? Is that possible? I still have the little unlocked symbol when booting up.
I've searched this forum and Google and haven't found anything, which could possibly be because I don't know what to look for. I've never had this happen :/
Currently running the stock 2.3.7

Nobody? I just need a little help.

Did you flash a superuser.zip after you installed clockworkmod?

Now I just need to re figure out how to backup my stock rom on rom manager. I need to do that if I'm going to flash a custom rom onto my NS4G correct? I've never actually gone that far with my phones lol.

Okay lol hold on so just go make sure you
1. Unlocked the bootloader right?
2. Flashed a custom recovery (clockworkmod)?
3. Flashed superuser for root access?
4. Now you have a stock rooted ROM?
If you have/did all that then yeah you could backup your stock rooted ROM, you don't need to back it up but its helpful just incase you mess something you could always restore it to start all over
And you could backup any ROM you install incase you didn't know, just remember when you install different ROMS make sure to do a proper full wipe which includes data/factory reset/wiping DALVIK cache, and formatting system and boot in the "mount" option in CWM. And now I think your good lol

Unlocked Bootloader? If I boot in fastboot it says Unlocked. Is this what you mean?
I have ClockWorkMod, but I haven't done anything with it.
I have superuser from the root
and I was working with a stock ROM the whole time....
I think I'm ok lol
So I'll back up my ROM, and flash a Nightly CM9? And back that up as well? Just perform a factory data reset before doing so, right?

Yeah if it says unlocked your good to go. The super user.zip you first flashed won't be needed once you flash different ROMS, it was only needed for stock because you didn't install a ROM you just unlocked the boot loader and super user just gave you root access that didn't come with stock.
Yeah backup your stock ROM JUST in case you encounter a boot loop so you can just restore and start over, you don't need to back up CM9 that's completely your choice if you want . Its convenient though if you like CM9 but still like to flash other ROMS that way you can just go back if you miss CM9 without doing the whole setup process.
And a full wipe is
Data/factory reset
Then wipe dalvik under "advanced"
Then wipe system and boot under the "mount" option in CWM

I'm not sure if I'm supposed to post links to videos or not. But I'm in love with some of the features this guy has on his NS4G
https://www.youtube.com/watch?v=IKdyAm3CgHc
He said it was a nightly etc.
The hidden status bar and bottom menu hidden is amazing. I also like the inverted G-Mail and Facebook. Is this all separate from the Nightly ROM?

Is it OK to Falsh CM9 on top of Stock I727UCLF6_I727ATTLF6_ATT

Hello all,
I have Samsung Galaxy S2 Skyrocket and i am currently on I727UCLF6 stock firmware I727UCLF6_I727ATTLF6_ATT, my question
Is it OK to Falsh CM9 on top of Stock I727UCLF6_I727ATTLF6_ATT?
If yes should i flash the nightly cm-9-20120721-NIGHTLY-skyrocket.zip or cm-9.0.0-RC2-skyrocket.zip is better?
Thank you

Have you done any of that reading we suggested you do? Flashing CM9 on top of stock without wiping the cache and Dalvik and doing a factory wipe will turn your phone into a brick, which you seem to be intent on doing. Seriously, if you have to ask a question like, "Can I flash a new ROM on top of my existing stock?", you're not ready to flash ROMs.
Read, learn and understand before doing, or you will brick, and you will find little sympathy here.

After the nightmare i had before when i lost my signal, MAN i did a lot of reading!!!1
I have successfully flashed my phone to cm-9.0.0-RC2-skyrocket.zip but before that i did some wiping as the following:
1- Wipe data/factory reset (Three times)
2- Wipe cache partition (Three times)
3- from mount & storage, format system (Three times)
4-Wipe Dalvik cache (Three times)

All the wiping really isn't necessary. Flash the rom, then modems if needed, then one factory reset and reboot. That's it.

Probably the UVLE1 modems from the T989 ics release.

or you could just follow the instructions the dev almost always posts along with the rom...
anyway, if the dev does not post instructions for some reason then just default to:
1) make a nandroid
2) wipe data/factory reset
3) wipe cache
4) wipe dalvik cache
5) flash rom and gapps if necessary
6) reboot
you obviously still do not understand what it means to flash roms, so until you do, just follow the directions EXACTLY as the dev posts them.
also, i would not recommend flashing a new rom before wiping then wiping afterward, sounds like a pretty dirty install

I don't want to end up loosing signal like what happened to me before Man it was a night mare...
OK I got the cm-9.0.0-RC2-skyrocket.zip ROM installed, so now what do you guys suggest for
radio + kernel combination along with the above ROM to get 3g/4g on my unlocked i727 using a Tmobile sim?

[Q] Flashing new kernel but keep current rom?

I have looked all over and there have been some people that have said how to flash a new kernel, and how it is basically exactly like flashing a rom and don't go into it any further.
Plus it seems like the only people i can find that even mention flashing a new kernel are also making a guide to flash a new rom, so keep the settings form an old rom aren't an issue for them or the people reading those guides.
I have found a rom that I like and want to stick with it, but what I am wondering, is if I want to test out different kernels for potential battery saving abilities, will I have to go through the same process in CWM of wiping the cache/dalvick cach/format system and stuff like that, or can I just flash the new kernel the same way I can flash a baseband, without changing any settings or worry about it deleting anything I have done?
I just don't want to go around *assuming* anything because last time I did that I had to spend 50 bucks on a JTAG
Thanks!

I only use KTkernel and.....
wipe cache
wipe dalvik
install kernel from ext sd or sd
wipe cache
wipe dalvik
fix permissions
rebooot

And just make sure they are TW if you are running a TW rom and AOSP if you are on that type of rom. And have a backup in case something goes wrong.
I have been flashing kernels on two different phones and have never had a problem. Just read and make sure you are doing it right.

Some people say you should wipe cache + dalvik before flashing a kernel, but that's questionable if you really have to. I simply flash and reboot, never experience problems. And definitely make sure it's meant for TW or AOSP, depending on which you are running.
