Hi guys.
I am a newcomer,so go easy please.
I have spent the last few weeks researching all things root to do with my galaxy s2,I am pretty much ready to go but I am unsure about what is installed on my phone.
I got the phone second hand, it has superuser and this works for things like greenify etc, so I assume the phone is rooted, but when I boot into recovery there is no clockworkmod or anything like it.
So then I dug deeper and read warnings about trying to install clockworkmod with custom kernels etc.
How do I know what method was used for rooting, and what type of kernel I have?
Basically I want to nandroid backup before I start tinkering.
Model is GT-i9100 4.1.2 Kernel 3.0.31 - 889555.
Thanks for your time, I don't want to brick my phone on my first venture!

Flash philz kernel tar with Odin or zip in stock recovery. That will root and give you cwm recovery :thumbup: but do read about it first. Don't just flash any old thing. Read read and read some more.
Thanks, I have read lots, not as easy as I was hoping. I might practice on my old htc desire first!
Easy way is to flash the zip as an update in stock recovery. Reboot system and you're done. Make sure you put the philz kernel zip on ext sd card not int sd.

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
Ok guys heres the deal....i recently got a samsung fascinate from my sister cause I couldnt mod my inc any more. ok so....i got the phone rooted. i have su perm. i downloaded rom manager and installed it. now heres my problem. i can preform a backup no problem, but when i go to restore that backup it boots into clockwordmod and begins and then get an error about erasing boot img. or something like that. can tell exactly if i get some help from this. also cant install custom roms like i can with my incredible. i know it can be done cause i see roms and all for this phone. can someone please please help me.
Thats because cwm3 will not perform nandroid restores on stock roms. You need to flash cwm 2.5.1.x red recovery. Its the best recovery imo for any bml(touchwiz) rom. Go over to my guide in general section and you cand find cwm 2.5 in section 2&5. Oh and ditch rom manager...manually install cwm via odin!
If you're coming from an incredible, also keep in mind you don't have to be rooted to flash roms either, you just have to have a custom recovery. There aren't really any modifications like rooting procedures, S-OFF, etc, required for rom flashing, just odin a recovery and flash your selected rom.
Hey there, I'm trying to root my S3 and a first step I wanted to make a nandroid backup, so i downloaded Odin and I used it to install recovery-clockwork-touch-6.0.1.0-i9300 onto my device, i rebooted into the recovery screen and I found myself in the stock recovery menu.
So i tried it once more, to no change in my situation, so I looked through the forums for a while and I found a thread by mskip about installing CWM and thankfully it had this
Stock Recovery being reflashed after a reboot?
There is an auto recovery restore system on stock roms that will reflash the Stock Recovery on a Stock Rom. If the restore files are renamed then CWM Recovery should not be overwritten after a reboot.
You need to be rooted and then delete or rename the following files:
Quote:
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
You can then flash recovery without it being overwritten.
You can also do all this through the S3 ToolKit
**All credit goes to to Koush and anyone else responsible for ClockworkMod**

My problem being that I can't rename said files bacause my phone isn't rooted and the S3 toolkit requires rooting to do backups and such, and I can't root it because (unless I misunderstood) I need CWM installed.
So my question is : What can I do now? Can I root my phone in any other way ? Is there a way to get past this Stock recovery screen onto CWM?
Already thanks for reading and sorry for it being this long
Also I have a Samsung Galaxy S3 GT-I9300 I have Android 4.1.1 And I run Windows 7 on my PC
Ok, so I looked around a bit and I just rooted it without a backup, it seemed safe enough.
Root went well, I backed up right after just in case.
Use cf root and flash via Odin that will give you root and flash cwm. Then you can continue with your nandroid backup. All though you can do the full root procedure using that toolkit, its one of the options. Hope I could help
Sent From My Omega'd Galaxy S3 ...
First the specs. Samsung Galaxy s2 GT-9100 running Android 4.1.2 Build XWLSH Kernal 3.0.31-889555
Need a touch of help here. Finally had the nerve to root the GS2 on the weekend and clean out all the crud not required... so far so good
Had no success in attempts to install CWM Recovery through ROM Manager (Recovery setup > ClockworkMod Recovery > Galaxy S2 i9100 > "does not have an officially supported...."). Also found the Recovery builds on the official site but no guides whatsoever as to how to install... oh so helpful
Finally came across a guide at galaxys2root[dot]com on installing recovery from download mode using Odin. Ran through the process and ended up stuck at boot with no way of proceeding. After a panic session, was able to recover from back-up (thank god I backed up the ROM and all data before attempting to install CWM recovery). Now I'm right back where I started with no idea how to go replacing the stock recovery.
Can someone please shine some light on the situation? At a complete loss as to how to get the CWM Recovery on the phone without bricking it.
Cheers in advance
1) Don't use Rom Manager. At all. Uninstall it. It will break recovery & cause bootloop eventually if you continue to use it.
2) Thread stickied near the top of Q&A has all the info you need. Essentially, any CWM you flash independent of the kernel will only persist until the next reboot. Reason being recovery is baked into the kernel on the S2 & isn't a separate partition like other phones. So you flash a custom kernel, you end up with rooted phone + permanent CWM.

A huge thankyou for pointing me in the right direction. I had since the original post found Mobile Odin (invested in the pro version) and installed the CWM Recovery from the their site... only for it to revert back to stock recover screen At least now I know why.
After much hunting around - I notice the stickied posts don't make it easy to find the correct kernel for for the AU i9100 - I found the PhilZ cmw6 kernel build.... used Mobile Odin to flash and all is now rosy.
Now question.... I was under the impression that ROM Manager was required as an install with CWM. I use Online Nandroid Backup to create full ROM/Data backups and trying out Nandroid Manager for selective recovery.... is that all I need then now that CWM is successfully installed in recovery?
Cheers again
Can't speak to those products as I've never used them, but Rom Manager & the S2 is a big no no. Doing nandroid backups, which is essentially a 'snapshot' of your phone at the time you make it, by simply booting into CWRecovery & also backing up apps/app settings with Titanium has always done the job for me.
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
