I have the Docomo version of the Galaxy S, SC-02B running 2.2.1 OMKA5 build. I have rooted the phone via Superoneclick. I have read through many posts but I have not really found a solid process or even if it is possible to get 2e recovery and CWM without having sim card or modem troubles.
Also, to my knowledge custom kernel and rom flashing cause similar issues. I would really like to do more with my phone, so if anyone has had stable success could you please post your method?

Follow this link if your not a Japanese reader use Google translate http://komugi.net/archives/2011/03/07104838.php
Thank you, I appreciate the response. I can read Japanese I will check it out and get to testing it out. I am surprised for the SC-02B being most popular phone in Japan, from what I have noticed not too many ppl are really doing much past rooting
Boo, he/she is basically confirming the same issues that the users on this forum encountered with their s-02b's.... Summarized from him other than getting 2e recovery on the phone, it does nothing
Actually you can have clockwork it is just inconvinient because it takes two steps to get to clockwork instead of one. Once you have 2e just download rom manager and your off and running. I'm doing nanodriod backups almost everyday so I can recover after I've failed to make a theme work or screwed up the phone in some other way. The big problem is their are no Japanese developers work on our phone and the other dev's are reluctant to develop for a platform that they don't have to test on.
According to that link the person said Rom manager didn't work...
If it does, than be able to make nandroid backups would definitely help me out a lot. Did you use his method to get 2e recovery, or another?
I used a different method but the results are the same. Can't find the link to the one I used. When he says it doesn't work I think he means that ROM manager doesn't boot directly into clockwork it boots into recovery and then you have to apply an update zip that puts you into clockwork the very first time you do it doesn't work and you have to apply it a second time. This is clearly explained somewhere deep in the ROM manager thread.
In his post shows clockwork running and mentions how long it takes to do the backup if your running OCLF.
Thanks for helpful information.

Good evening,
I usually use Windows Mobile devices so very new to Android, but my girlfriend has recently purchased a Galaxy S from Three. I have tried looking in the FAQ's but there is that much information I am feeling a little confused and dont want to go bricking a £380 phone.
Anyway, the phone has Three's customisation on it and it's not good to put it simply and I am wanting to return the phone to stock ROM or possibly a custom ROM.
The phone is currently running Android 2.2 as it updated when we first got it using the Samsung Klies.
Please can some of you offer advise on where to start with this as I presume I will need a backup of the ROM currently installed.
I've tested the 3 button download mode and that works fine.
Many thanks.
Well with the 3br you can pretty much do anything I would probably flash different kernel which has 2e recovery either speedmod or cf root then install rom manager and from within that app install cwm this enables you to flash custom roms preferably jpy 2.2.1 or just use odin to flash roms that are available from samfirmware again id recommend jpy.
It is worth reading everything you can before you start rather than posting in panic if it goes wrong. You can also break the three button as many have discovered lately to their loss. It is always a risk. So make sure you know wha your doing before you start and remember her warranty will probably be voided by doing any flash.
Hello,
I read most of the guide but couldn't find certain answers there nor by search, but apologies if I missed them elsewhere.
1) I'm happy with my SGS, I always used stock ROMs and am now on 2.2.1. I'd like to get root access and leave the rest as it is, however.
Is there any way to get root access with the stock 2.2.1 ROM without switching to a completely different ROM (as said, I like the stock ROM and don't feel like changing the layout, features and all that come with a new ROM)?
I saw that superoneclick thread but apparently it didn't work for everyone and questions are usually not answered there if people run into trouble so I didn't dare that yet.
2) Still a bit confused about the 2 modes. Do I need recovery mode to work? Or will download mode do to flash (if I have to) and rescue/fix my phone if something goes wrong?
My 3 combo button never worked so I bought a JIG dongle on ebay which gets my phone into download mode at least, but I still have no recovery mode yet that's why I'm asking.
Thanks!
There's an app called Quick Boot which will allow you to get into recovery mode but you need to have phone rooted.
Note though that Froyo uses 3e and I've tried to use update zips, wont take without going down to 2e recovery.

Warning etc I take no resposibility if you break something etc
First of all fix your 3 button for recovery, there should be some guides around here.
1. Try that superoneclick you posted the link to. If it wont work it wont work... But it will.
2. Recovery you need only if you want to tinker with the rom a little more and to do nice stuffs like backup. Or for a recovery
Oh and I am on stock rom + custom kernel + another modem and happy with it.
First I was rooted and the rest was as it is and I rooted with the super one click root . Dont forget USB debugging on. Once you root though I think wont be long till you start customizing a little . Good start is a nice good custom kernel
If you want to stick with stock you could try these stock roms which come pre-rooted, zip-aligned and deodexed (making them smoother and allowing the application of themes).

To fix the three button combo have a read of this thread. The OP of this one is really helpful if you're not sure what to do. I had to do this and it was the most nerve racking thing i've done to my phone as if this screws up you'll be sending it for repair.

Thanks a lot to all of you for your answers!
Had my first successful flash today (3 button combo mode) and will now take a more in depth look at rooting etc.
So far, I feel more comfortable to try a rooted stock kernel maybe instead of superoneclick.
However, if I had to unroot for any reason, how can I do that if I flashed the kernel?
The way I understood about ROMs and Kernels is that ROMs already contain kernels. So flashing a stock ROM would get me back to a stock kernel and the phone would be unrooted again?
you can also just flash a kernel and root such as cfroot or speedmod..

To un-root you can just flash a stock ROM (look in the general section to find them).
If you like stock ROMS then like the person above stated you can just flash a pure stock ROM then flash a new kernel (i.e. speedmod, voodoo etc.).
Good to hear the 3-button flash worked for you, now it is very difficult to brick your phone as you should always have the 3-button download mode which enables flashing with Odin.
Just be careful when picking a stock ROM, especially if its new, to check if it includes a new bootloader!!
Thanks all again!
and good on you for being sensible enough to get a jig.....best fiver I spent in ages. Every time I flashed back to an early stock it trashed my bootloader.
no worries about flashing now

Mate if you just want a simple to apply root access I would just use Z4root... its not used so much anymore but it works well and can be installed by just installing the app(can't be obtained from android market, internet only)..
Link: http://forum.xda-developers.com/showthread.php?t=833953
otherwise you can just use Odin to flash CF-Root ( I do this all the time on stock firmware and works perfectly every time).

I used z4root on 2.2 but afaik z4root no longer works with 2.2.1.
I did flash the CF Kernel now and quite happy with it so far.
By the way, is it a bad idea trying to flash with Odin if the phone is connected via a USB hub instead of connecting it to the direct usb port? Each flashing failed on the 1st attempt (worked on the 2nd), no matter what I flashed so far. Some searching here indicates a hub is not recommended.
If that's the case, why is that not mentioned in all those read-me-first guides (or maybe I missed it somewhere)? Not every first-flash user will have a JIG at hand.
You're right you should have the USB cable plugged into a USB port on the motherboard (not a port in your pc case or a hub) for the least chance of flash failure.
Not sure why though tbh, I think it may have something to do with the Samsung USB drivers that get installed with Kies being a bit flaky.
Hi,
I've been reading and searching here and on other forums for a while now and there seems to be no answer.
Got my new Orange branded SGS I9000, tried rooting using z4, which took ages then did the vibrate hang thing and rebooted the phone, unrooted. I assumed the z4 exploit was patched out in froyo. A few minutes on XDA and I succeeded rooting with SuperOneClick. Backed up efs, Installed ROM manager, tried and failed to install CWM.
It seems that in order to be able to install CWM (or any kernel/rom updates really), I need to go back to 2e recovery.
Multiple threads discuss this exact issue and many users report success in downgrading to 2e recovery using Chainfire's CF-Root. The thing is, that thread (http://forum.xda-developers.com/showthread.php?t=788108) does not have a xxJPC version.
It's very frustrating. In order to be able to safely play around with interesting roms and perhaps solve my nerve shattering lag issue, I need to do a nandroid backup, which requires CWM or a similar recovery, which are all signed using an old signature thus requires stock 2e recovery, which requires a JPC CF-Root, which.. does not exist
Is there anything I can do to go back to 2e?
Ever since I rooted the phone feels much more laggy. There's a frequent keyboard lag and booting takes about 7 minutes till the homescreens fully appear
According to everything I read here, just about any of the newer roms will most likely fix the lag. Even voodoo on it's own should do wonders, right? I just need help getting to a proper 2e recovery to be able to get there. Curse samsung for adding yet another hurdle on the way to freedom.
Suggestions or insight of any kind would be greatly appreciated.
There are other kernels that include 2e recovery like speedmod.
Will 3e let me install speedmod just like that? Is it signed differently than CF-Root?
Thanks for the unexpectedly quick response!
I have a friend that want's to flash a custom ROM to his captivate. He has it rooted but hasn't done anything else.
I said I would install CM7 or something on it for him. I had a Droid and Droid2 and am now on a Thunderbolt. So rooting and flashing ROMs aren't new to me. But, as with all three of my phones, things are a little different on the Captivate.
I see there's this Odin thing and I think no permanent clockwork recovery? How do you install ROMs on the Captivate? I see there's a new CW that doesn't need what ever Odin is. He's on the stock kernel and everything. So do I just boot into recovery and flash the clockwork update.zip and then flash normally through CW?
Also, being as he doesn't know how to do any of this, which is the most stable and bugless ROM that everyone uses. He won't know how to flash something else, so I need something that is as close to 100% as possible, speedy, and close to, if not ASOP.
Thanks
Hello,
Please post in Q/A as this is not a development topic. Suggest mod move the post.
I suggest that your buddy do some reading. Are you going to be there to hold his hand every day if something goes wrong with his flash? Tell him to educate himself. And if flashing is not new to you and your 3 phones, you should know what section a question like this goes in, is it "android development" related?
Sent from the frozen tundra known as Canada.
Most stable rom I have ever used is firefly 3.0. But your friend should see u do it and at least know how u did it to his phone. And yes from stock just do the clockwork mod update.zip and then flash through clockwork mod, there is a little more involved in flashing cm7 and it is not the most stable rom anyways. Good luck and I hope u take my advice on firefly you won't be dissapionted
The flashing procedure will vary depending on what ROM you want to run.
CM7/MIUI have their own set of procedures.
Flashing a Froyo based ROM you'll have to flash CWM 2.X then the ROM
Flashing a Gingerbread based ROM you'll have to flash the updated Gingerbread bootloaders first via Odin then flash the Kernel or CWM 3.X or higher, then the ROM.
Post in question section plz
I advice you to start flashing a not complicated rom (2.2) , once you get the hang of it then you go advance.
Moved to proper forum.
Odin is a program that is ran in the computer to flash a rom, bootloaders, and kernel at once. For it to work your phone has to be in download mode. Clockwork works with rom manager in the app store, some roms have it in the kernal.
Sorry, the forums I used before all root related things, including questions, went in the Root section. I thought Q&A was for non-root/development questions.
Thanks a lot Dustin, Kyuta, and bassplayer for the information.
I am going to show him how to do it. But I'm not going to hold his hand every time. That's why I wanted something stable where he wouldn't have to flash something else to get functionality that was missing.
Hi Everyone,
I bought ROM Manager Premium v4.5.0.1, in order to do a Nandroid backup on my I896 running stock I896UXJL1.
I ran "Flash ClockworkMod Recovery", and it said my Current Recovery 2.5.1.2 was the same as the Latest Recovery. So far so good.
Then I ran "Backup Current ROM." Instead of doing a backup, it rebooted my phone into Recovery "3e" every time. I tried it many times and got the same result.
This is so confusing. For whatever reason the app decides to boot my phone into recovery instead of doing the backup, I would expect it to at least go into CWM Recovery instead of the stock 3e.
Questions:
1. Has any of you gotten rebooted when you try to do a Nandroid backup?
2. Has any of you gotten rebooted into stock recovery even when CWM is installed?
Thanks.
KK
In general ROM manager is trash for SGS. Don't bother with them. I would say find a kernel with CWM cooked in it but JL1 is a rogers only and I don't know any for that.

froyo wasnt so damn kenel picky. any froyo kernel will work.
Doesn't work with any ROM
I've tried ROM manager after flashing KH3 and KJ3, and the "Reboot into Recovery" still doesn't work. I get the triangle-exclaimation-droid screen with nothing else, and it stays that way until I use the 3-button reboot.
Since the app can't even perform one of the more basic functions, I am afraid to let it do anything else. I wish I hadn't paid for the premium version.
ROM manager doesn't work on Gingerbread..... Rom manager isn't very good for Samsung phones

Stop what you are doing and read. ROM Manager sucks basically. Very few people on here actually use it. If you keep just throwing things at your phone though without knowing what you are doing you are going to end up with a shiny, expensive, paperweight. Then you get to spend upwards of 50$ getting that fixed. So please, for me, the forum, and your phone just read. Or at very least ask a directed, detailed question. As in: my phone is here, im trying to get to there, this is what im doing and this is where and how its failing.
Flashing using an app
I actually did weeks of reading before flashing my phone for the first time. I got scared by potential problems such as USB interruptions.
This is where I am at: I've been using mostly Odin to flash. I have successfully flashed KH3 and then KJ3 (with KF1 bootloaders and Boog's kernel); however, I am still nervous each time I do anything.
This is where I hope (or used to hope) to get to: I keep looking for a way to minimize the probability of human errors and technical hiccups. (It's a habit I've picked up while working as a software manager.)
I went for ROM Manager because the same developer wrote CWM. I do appreciate you guys sharing your opinion of the app's effectiveness with the SGS. I only wish I had been warned sooner (ideally by the app's developer).
Find ODIN packages that don't inlcude bootloaders. That will only minimize your risk to soft bricks wich can be recovered with a jig that are easy to make and only cost ~ $10 if you choose to buy them. I personally use KH3 as my "stock" setting when I need to flash to stock. I use Cezar's KH3 .tar that doesn't include them but there are atleast 1 1 click around.
CWM for Captivate Gingerbread UCKJ2
Sorry in advance for the noob question. I have read many posts but can't find my answer. I've installed the leaked gingerbread rom from Samsung called uckj2. I was trying to change the modem by flashing a zip file using clockworkmod recovery. I've heard the way to do it is by using a kernel that already has cockworkmod already baked in. Which kernel should I use?
Thanks in advance
KJ2 have 3 kernels that should work. Corn kernek, Samurai and Boog's kernel.
