I have just bought an SGS2 to replace my HTC Desire.
I rooted it using SuperOneClick. It seemed to work, I can run apps requiring root now.
But the very first thing I want to do is make a nandroid backup of the phone in it's out of box state (or as close to). Is it possible?
On Desire you had to root first, then install a custom recovery such as CWM, and then do a nandroid backup from there. So I guess I will have to install CWM. But googling tells me that on the SGS2 I have to replace the entire kernel to get a new recovery, is that right? And how do I do that?
If the only way to make a nandroid backup is to install a new kernel, I guess the backup will contain the new kernel. Is it possible to go back to the out of box state with the original kernel and original recovery and no root etc.?

Flash em via Odin and you'll have CWM take a backup and you are good to flash any custom ROM
Just take note what your stock firmware and kernel is and if you ever need to send off to Samsung you can just flash back to stock using intratechs stock rom thread

Hello everyone,
I have SGS2 with latest stock firmware (XWKI4) for my region.
Now, I would like to start playing with it with roms and such (yes, I already have Jig just as safety net), however I would like to creat as close as possible original configuration.
Now, I have rooted the phone with zergRush by Doomlord sucessfully and made efs backup as well as kernel image backup via HC-kTool. (This is kernel image backup right?) This way I presume I got pretty much untouched kernel image except rooting, right?
What now I would like to do is to make ROM backup and install some recovery. I know that Clockwork that comes with Rom Manager isnt exactly the same as Chainfires CW that comes with CF-Root and I know that Chainfires CW is optimized for Samsung phones (not to mention that they are not compatible with each other).
I guess my question would be is above that I did make sense, and shall I install CW from ROM Backup or get some CF-Root kernel with CW? I mean what do I lose with each solution, or any other advice how to complete ROM backup so that I can recover it if something, God forbid(knock on the wood), gets fishy?
Cheers

If you take some time and search different threads in xda developers forum, you will find many user posting statements not to use ROM manager.
As I do not use ROM manager at all, I did not read the whole posts. That's why I do not exactly know, what the issues are about ROM manager.
(Incompatibility with many ROMs and kernels, but there must be more issues.)
I am using CWM Manager app (included in Chainfire's CF-Root kernel) or CWM5 recovery mode to create a complete system / nandroid backup.
So, in case of an emergency I only have to flash a kernel containing CWM5 recovery and restore my last system backup.
Just to be on the "safe" side, I also copied my efs folder to my external sd card.
And all my apps (+ app data) are under Titanium Backup control.
So, I recommend to use plain CWM recovery backup.
If you are not sure about ROM manager, please search the forums and make up your own mind.
Good luck !
So basically, I can instead of Rom Manager install DarkyROM2 Tool, flash some kernel with CWM support e.g. Hellcat, CF-Root, and boot to recovery and make backup of current rom(with higher compatibility), right?
Sorry if this is obvious, but I have just started with this kind of tweaks...
Hello everyone,
I'm just about to go out of my mind, haha. I've successfully rooted my phone and I am interested in installing a new, custom ROM. However, I want to be 100% sure that I am not leading myself into the path of bricking. I have a couple questions that I think are basic enough, but haven't found an answer to anywhere online.
1.) Do I need a specific kernel and/or firmware in order to install a custom ROM?
2.) These are my specs for my phone
Android 2.3.3
Baseband: I9100DXKI1
Kernel: I9100DXKI2
Looking at my specs, will I be able to install this rom: http://forum.xda-developers.com/showthread.php?t=1198334 ?
Will any other ROM work for my phone? Now that it is rooted, am I freely able to install any ROM using clockworkmod or odin without having to change the kernels?
I'm very new to this and I'm hoping somoone can help me out with this.
Thanks a ton in advance!
Just rooting is not enough to install custom rom. You need to install clockworkmod recovery either through rom manager or flash a custom kernel which has CWM.
You can flash any kernel compatible with your device (for example, you cannot flash I9100G kernel/firmware on I9100 model).
You can get a lot of information here at xda. All the developers here are very friendly and co-operative.
You're good to go. Backup apps and some data using Titanium backup and/or My Backup Pro or something like those. Then boot into recovery, make a nandroid backup (can be found in the recovery menu), and flash the rom of your choice. You can flash any rom you like, just don't forget to wipe! This is also an option in recovery, wipe data/factory reset. You can also wipe dalvik-cache (found under 'advanced'). Have fun flashing!
Thanks for filling me in guys. I do have CWM installed on the phone, so I'll back up and try to flash. We'll see if I don't brick the phone somehow, haha.

Well obviously you wont, all you can do with flashing a wrong rom is getting boot loop, you can always restore your previous rom via nandroid backup. Happy flashing
First of all, I'm not a noob.
Secondly, I've already rooted my phone using the Framaroot method. (OS is JB 4.2.2)
Now now, i want to backup my stock recovery and my stock ROM.
I know i can backup my stock ROM using CWM recovery, but if i do that, i will lose my stock recovery.
So first i have to backup my recovery somehow, and then i can install CWM recovery and then use any custom ROM i want.
So, just tell me the quickest way to do that.
Pathathic forum
So now it's confirmed. This is the most useless forum ever made. This is not the first time i have asked here for help, and this is not the first time i haven't been helped here.
F*** this ****. I'm never visiting this s***** website again.
Would the following work as a way to try out, for example Cyanogenmod 10. I am currently running a 4.1.2 install (pretty much stock just rooted/cwm via Philz as per the tutorial). I have a complete backup made via Philz recovery of this rom along with the kernel (which I believe is still stock from that) and efs.
1) Install a custom kernel (eg. dorimanx 9.x?) via the Philz recovery.
2) Install cm-10.2-20140102-NIGHTLY-i9100.zip.
3) To return to the original rom, reflash the original kernel (with whatever CWM is included in dorimanx) - then reflash the backed up rom via the same recovery?
I hope this is clear enough a question.
I believe you have to flash a stock rom through Odin, to return to complete stock. Just flashing a stock kernel isn't enough, and is surely not going to work (so don't do it).There are also tutorials how to remove the yellow triangle afterwards.
Please correct me if I'm wrong

This is the part I'm most unsure of. Ideally I'm trying to figure out the process that lets me go from CM10.2 (and whatever recovery) to the point I am running the backed up rom rooted with PhilZ-cwm6-XWLSW-XEU-5.06.1-signed.zip again. Very confused on how to do so.

Topher,
If you have rooted and cwm via philz, you already have a modified kernel installed. I believe the philz-cwm6 should be as close to stock kernel with the CWM incorporated. You don't need to add another kernel, because it will be replaced when you install the custom ROM. You should just be able to flash the cm10.2 via philz or via odin. You can then flash the dormanix kernel if you want - can't comment on that kernel - or if it has cwm included.
I would also suggest that you consider backing up you /efs folder (one with you imei information etc) prior to flashing any custom roms. People have been using hcKtool to do the backups and also an actual copy as well.
Depending on the custom rom, you may have connection problems with your network. So you may want to consider keeping a copy of your modem.bin file from your stock rom handy in case you need to flash onto the custom rom.
If you want to go back to stock, then you just need to flash the stock rom - you can check sammobile website for your stock rom or use the backup that you made.
I should point out that I have yet to do any of the above - I gathered this from reading the forums. Some more experienced forum users can add corrections. I rooted my phone a couple of months ago and now considering installing custom rom in the next couple of months.
Thanks.
if u flash a custom rom (cm10.2 for example), it already included kernel as well. so if u want to try out other custom kernel, i can flash it after you are done flashing a custom rom but make sure it is compatible with your android version. (u cant use custom kernel that not support android 4.3 with a custom rom running android 4.3)
Hello,
So lately I've been have some troubles with my phone and I decided to try and flash with a new ROM and see if that helps.
I've been reading on the forums some of the guides, FAQ, and read about some ROMs but I'm still a bit unsure of the entire process.
Currently using GT-I9300, 4.1.2 OS, stock.
Backup:
1. Do I need to flash a custom recovery tool (CWM/TWRG) to create an image backup? Should I just root with Odin and then use Titanium?
2. Do these backup my EFS partition or should I back that up separately?
3. Do I need to root my phone with Odin to be able to flash custom recovery tool/backup my EFS?
ROM/Kernel flashing:
1. Since I'm a newbie to this and there seems to be a ton of ROM options, could you recommend on a stable CM based 4.3 ROM I could use?
2. I haven't seen a stock 4.4.4 for GT-I9300, is it stable to use?
I'm sorry If I've asked something thousands have asked before, I couldn't find a clear answer in a decent amount of time.
Thanks for the help!

Backup
(1) Titanium only backs up apps and data it does not do a full (Nandroid backup Google it) Root with cf autoroot http://forum.xda-developers.com/showthread.php?t=1980683 and then flash a custom recovery (choice is yours cwm,Twrp,PhilZ flash with Odin)
(2) Yes some custom recoveries back up efs PhilZ does I think twrp does not sure about cwm ( I don't think it does maybe wrong on that) nandroid backups don't backup your efs do this separately
(3) Technically you don't need root to flash a recovery but if you want to backup anything in recovery then you need to root.You will only need to root your phone once if you are intending to flash custom roms (so that you can backup) because root is included in custom roms.
IMPORTANT! You must backup your efs once you have flashed a custom recovery especially coming from 4.1.2. and keep multiple copies on phone and pc!
Rom/Kernel flashing
(1) We cannot recommend roms it is against XDA rules
(2) Their is no stock 4.4.4 roms last release was 4.3 anything else is a custom/port of 4.4
Thanks for your help, that cleared up a few things.
I ended up using samsung galaxy S3 toolkit (which is amazing btw) to root & load insecure boot image, flash custom recovery img and backup everything on my phone.
I'm now ready to flash my first custom ROM
Again, thanks a bunch
