As I mentioned in my other thread, I have a second hand US SGP 5.0. I really want to try some other ROMs but I want to create an image of my current setup just in case something happens. I've read that CWM can make full Nandroid backups so is there a way I can install CWM without flashing to a new ROM to make the backup of my current setup? I only see threads for new ROMs that include CWM but not a thread just for CWM.
Alternatively, if anyone can suggest a way to make a full image of my current setup without the need to flash anything, that would work as well.
Thanks!
CWM is included in custom kernels. just make sure to flash the CORRECT kernel with odin and u shall be fine
So just to clarify I can flash a custom kernel without flashing a new ROM?
Can I still hang onto the hope of being able to just install CWM without flashing anything? I would really prefer to make a full Nandroid backup of my current working setup before exploring new ROMs.
Thanks!
Yes you can flash just a kernel with odin. There is a way to install cmw without a custom rom or kernel but the galaxy player is a rather shunned device so sadly not for us.
I'd recommend flashing terrasilent, and if anything goes wrong theres stocks on this forum you can flash back to.

He have a 5.0 so depending from his device region, he would have to flash either rj's or entropy daily driver.

Is it ok to flash a custom kernel on top of another custom kernel?
Sent from my GT-I9100 using xda premium
You dont need to revert on the original one before flash another custom. But you need to format dalvik cache and cache in recovery before flashing or you probably have a bootloop.
I suggest to make a backup of the rom in recovery, so If something goes wrong you can enter recovery and have the latest known working rom back in 2 minutes.
Please note flashing kernels always have a very small chance to corrupt your efs partition, its suggested to backup your efs folder before start play with roms and kernels. How to backup the efs, use the search tool of the forum

Thanks for that. I know how to backup efs. Can i just use nitrality instead of ADB? To flash ROMs does it need to be in a specific firmware like sgsl or is it ok to have different firmware from the base of a custom rom?

I know my english sux sry:
Depends on the kernel but usually it is listed in the kernel thread the how to (odin or clockworkmod), clockworkmode is already on your phone if you rooted it with cf-root.
Now, to enter clockworkmod recovery, just push volume up + home + power button until the S2 bootlogo appears, then wait few seconds.
About the kernel type, i always flashed any kernel despite of my baseband, the difference is not so big.
if something is not working, you can always youse the nandroid backup (the backup done with the recovery cwm (up+home+power) and get back to the previous rom with previous kernel.
Im not really in the kernel "how to" someone else can prolly give you more detailed info, but as for me, i flashed ninphetamine 2.05 and 2.1.3 in cwm and it worked.
But.. as always, the kernel developers got a how to install in their kernel thread, so just read those and be sure about if you need odin or clockworkmod, if you are not sure, DONT flash anything until you are sure on how to proceed or wich system to use for flashing, better keep an old kernel with a working phone than have a brick to hold the papers
PS: also almost all the roms on the S2 forum are flashable with the clockworkmod, only few (like the lite'ning) are flashable with odin.
Again, i know im boring, dont proceed if you are not sure, better ask 10 times instead brick your phone

Yes not a problem flash as per the custom kernel instructions .
Kernel can be changed within an individual firmware or custom rom .

Thanks for the reply guys. Coming back to my second question. What if i have KF1 and the rom i want to flash has a base of KI3, should i flash to stock KI3 first before flashing the custom rom or is it ok to flash a KI3 custom rom without flashing first to stock KI3?
Sent from my GT-I9100 using xda premium
The custom rom first, the kernel after.
I got the habbit to boot succesfully at least once the custom rom. If everything is ok i then flash the kernel. Better do 1 task at time.
You can decide to try the rom without change the kernel..and try a different one if you experience battery drain or other problems.

If i am on KH3 and want to flash a custom rom based on KI4 then i would flash stock KI4 and KI4 root first .
Custom rom flashed i will often try a different kernel later .

from my experience
I have found that when i upgraded rom from gingerbread to ics that most custom kernals work with these roms ie now running with xxlpw ics (from gingerbread) with xwlp7 kernal. from what i have read on other posts and threads i could swap kernal to siya or any other as the mega good developers have made them (hotswappable) interchangeable as previous reply said swapping kernal might give you better battery or solve overheat probs.
Eg iwas running darkys rom with siya kernal v?something my phone rocketed temp in short time so i swapped kernal for an up to date one (could have used older one) it solved problem.
Anyone feel free to correct explination im still learning too lol

I'll just point out this thread was dead since Sept 30 before you posted...
Hi!
I'm a total noob. This is my first android phone. I've read everything about rooting, and I'd like to install a custom rom, but I'd like to save the stock rom/kernel first. I've found this topic: http://forum.xda-developers.com/showthread.php?t=1075278
I don't really know if these are what I need. Also, I have an xwkf3 device, but it's slightly branded for hungarian T-mobile (the browser has a different name and icon, and it also had every network setting by default).
So, basically I either need someone to tell me which one to download, or better yet, how to create a backup of the whole thing.
Yet again, I'm sorry for asking something probably really stupid. I've tried to google it many times, but I failed to find an answer. Thanks for everyone in advance.
Are you rooted already? If so just boot into ClockworkMod recovery (cwm) and then navigate to backup. (navigate using volume buttons and use home to select)

Here is the kernel rooting thread.
http://forum.xda-developers.com/showthread.php?t=1103399
Dial *#1234# into the phone dialer to find out what firmware you have installed.
Root using chainfires method and make a full backup via CWM.
Flash away. But make sure the Rom/firmware is for your device. Eg i9100 international.
Good luck.

I'm not rooted yet. If I understood everything correctly, the safe kernel is the same for branded/unbranded devices, and only the rom is different?
I'm currently downloading both secure and insecure kernels. After rooting, can I revert back to the secure one to install custom roms?
BTW, thank you for your quick answer

I'm not positive but I think if you are rooted and install a stock kernel (without root) you will lose root and won't be able to flash custom roms or make Backups. Its really easy to root, just find the appropriate insecure kernel, flash it with Odin, make backup, and then try new roms!

Don't flash back to stock kernel.
Use a jig if you want to get rid of the yellow triangle.
Edit: after flashing one of the cfroot kernels make sure you can get into CWM recovery mode. Vol up+power+home
If you can then you're ok to follow the instructions of the Rom you want to flash.

Thank you. One last question, if I may. Some of the roms I'd try use different kernels, then mine. If I install one of those, and want to revert the phone to factory rom, and kernel, should I root it again with an insecure kernel according to the rom, or one according to my device's current, factory rom?
You will probably find that the Rom kernel will be rooted and have CWM. Just check in the 1st post or 2 of the roms thread.
If you use CWM and make a backup of your stock Rom, after you root now but before you flash any other Rom, you can restore with CWM to get back to stock firmware.

To fully return to stock you have to flash a stock rom and stock kernel from Odin. The rom that you want to back up will be a stock rom but it will be rooted because of the rooted kernel. So yea, flashing stock firmware and kernel is the only way to get back to fully stock.

But if I restore my backup rom, and flash it with an original kernel, it would be unrooted, and basically the phoen would be just as it is right now. Is that right?

hi i have the same problem i want to root my gt 2 p5110 but i have to come back at the original values before june and can't loos the warranty....can you help me?
Sorry for being a bit dumb, I used to be on XDA all the time when I had my x10 but that's some time ago now!
I want to flash an original unbranded uk 2.3 ROM on to my phone. No tweaks, rooting etc
Can someone please help me find one or link me to the relevant thread?
And once I've got the ROM what do I need to do? With the x10 it was a simple case of place the zip on the sd, boot into xrecovery and flash. Is it the same with the GS2?
Curious as to why you'd want to put a 2.3 GB rom on your phone ? Anyhoo, have a look at this thread. If you find links don't work, note the details of the firmware you want & search Samfirmware.com for it.
Want to install unbranded GB so I can get the official ICS update via Kies. That would work - right?
Yep. If you install 'correct' stock rom for your region it should give you the correct CSC for your country & you should be able to get Kies updates. If it doesn't work, you can always grab ICS stock roms from here/elsewhere & flash them manually.

Just a tad confused as there's so many ROMs to choose from!
I've installed Clockwork Mod, is it now just a case of find the correct ROM, stick it on the SD card and boot the phone in recovery?
Doubt you'll find many stock roms that are CWM flashable.
The majority (all ?) are Odin flashable, because people tend to go back to stock to either get a 'clean slate' they can then install custom roms/kernels over if they've had problems, or if they're sending the phone in for warranty service/replacement.
Right, so gotta work out how to use Odin....cheers!
So that means that custom ROMs can be flashed using CWM?
Sent from my GT-I9100 using xda premium
Many (most) custom roms are CWM flashable. Some also have Odin flashable versions.
That's what makes trying custom roms so easy, you backup your existing rom in CWM, flash the rom you want to try, if you don't like it you restore your backup & go back to your previous setup. All in a matter of minutes.

As to the last post .
I have custom GB rom and want to try but not buy ICS custom rom .
Nandroid backup of full existing GB rom and all apps and settings via CWM recovery .
Flash ICS custom rom via CWM recovery test it make a nandroid backup also .
Boot CWM recovery and go back to the exact GB settup and i can even restore the ICS rom again .

Hell everyone,
I have a couple of questions regarding the installation of custom roms.
Does anyone know why there is a requirement to first flash stock firmware before flashing a custom rom in sola?
kernel, rom, recovery, all come with the custom rom, so why is that? (my main device is a nexus so this requirement is very odd for me)
On a second note, if you do a nandroid backup say of cm9 FXP205, and go to whatever other rom, do you need to flash stock again before restoring the nandroid, or you just hit recovery and restore?
thanx and forgive my ignorance on this matter

For the first question
We always ask to flash stock ftf for two reasons
Firstly to get modules and certain dependencies from the stock rom ( thats why in cwm first rom is flashed and then system is wiped and not vice versa)
If u dun do that u will get installation aborted in cwm
Second question m nt sure coz I never restored trans rom nandroid
Bt bt bt.... Since we usually have nandroid backups of upto 1gb, I DUN THINK flashing stock would be a requirement
If m wrong plz correct me
Nandroid backup
For your second question, i have used nandroid backup in x10 mini pro to restore custom rom and saw no issues.
But in my xperia P sometimes I noticed that nandroid restore does not restore the custom bootscreen!!! But if you used advanced restore and restored every partition one by one issue seems to have fixed. So am not quite sure about the nandroid restore.
Thanks for the replies. However, any required modules/dependencies could be passed along with the custom rom, as it happens in other phones? What makes Sony phones unique in this aspect?

You are correct that the modules and others can be passed on through but that will increase the size of rom.So stock based roms can use the files already left behind by the stock ftf and hence there would be no need to include these module/dependencies files in the flashable zip.
Also stock based roms do not need to have kernel file as the stock firmware's kernel is already present on the phone,again reducing size.
The presence of locked bootloader makes sony phones special(although there are htc and motorola also).
In brief when u are going to install a rom that uses custom kernel,you need to have bootloader unlocked,so that custom kernel(not signed by sony)
can be installed e.g CM9.On the other hand if you have locked bootloader,you can't use custom kernel based roms and use stock based roms only e.g pulak's ultimate sola rom.
Hope this helps.
Dear all,
The official latest CWM release for i9100 is v5.8.3.1 (see www.clockworkmod.com). Is there an official (or fully working version) of CWM 6.0.3.x for the i9100? For e.g. T-Mobile there is a release available. Can I use this as well?
for now, I can also flash Philz kernel to get CWM v6.0.3.2, but I first want to have a separate CWM version installed. Thanks for help.

I'm also trying to install/flash latest cwm without being part of any kernel / mod. Did you have any luck with that?
Philz IS stock kernel.....no tweaks, no mods......other than CWM and root.......afaik.....if you want a (cwm + root) stock phone, philz will give you that.......
My Wife says I'm a phone geek.....
I'd have to agree.....
I don't see why I should install a kernel, even stock, when only recovery partition needs changing. In most phones there are flashable files through adb, or similar ways, to install cwm. Will it work through rom manager app?
I'm not sure about just CWM on its own. It probably does exist. Just needed to jump in quick.... DO NOT use ROM manager on an i9100. Sure-fire way to screw things up /brick.
Ps. Keith is right, the only thing different about PhilZ kernel is recovery and it's rooted. Nothing else is changed.
Sent from a galaxy far, far away
And when you add the fact that it can be flashed using the stock recovery.........
It doesn't get any easier, safer or straightforward than that. No disrespect intended, but I can't see the problem with doing it this way.......
My Wife says I'm a phone geek.....
I'd have to agree.....
You really are trying to make this as difficult as possible for yourself, aren't you ?
Take the good advice you've been given; particularly the bit about staying away from Rom Manager unless you want to find out why you don't use it with the SGS2 the hard way.
Will do that... however, I'll try to make a flashable zip (with stock recovery) of latest cwm alone, and will report back... just in case someone wants it in the future.
