There is a very good write up on how to root 2.1 by craigcrawfore, i know his same post is on droidforums.net and also modaco.
heres the link, worked for me, on my uk milestone with 2.1
http://android.modaco.com/content/m...m/308422/milestone-2-1-update-and-root-guide/
cheers for this craig, im sure ive seen you on xda before.
Does rooting voids warranty? A noob question though.
Kinda...legally, the dont have a leg to stand on if the fault isnt related to the root, but overclocking etc could result in hardware failier due to root. There should be an unrooting method or else get an official update package from moto (RUU sorta thing) if you wanna take take your device back
Thanks for the quick reply. My device is getting hotter even with underclocked 550MHz. As u said overclocking on this device had more chances of hardware failure. Ok if i find any package to unroot n get me back to stock, i will try rooting.
If I root my milestone and motorola releases FROYO update, am I be able to update to FROYO without any problem? or Do I need to come back to stock n then update?
I will load the 2.1 sbf file or the 2.0 or even 2.0.1 version. Then do the ota updates.
The unroot method would be download rsd lite and then load a sbf file.
Easy and under 5 mins! U will be completely factory reset at this stage.
So Froyo is supposed to come out in September.
I'm debating rooting my phone now but keeping the stock rom.
Will there be issues upgrading to Froyo when Samsung makes it available?
Will I have unroot, etc?
Thanks.

Anything we tell you would be a guess...
I guess better questions would be:
Does anyone plan on doing anything special when the update comes out?
Do they expect things to work smoothly?
Do you plan to unroot, upgrade and re-root?
Thanks.
As far as I'm aware, rooting 2.1 on the Galaxy S is as simple as installing a few files which allow you to run things as root, no horrible kernel hacks or such necessary. This means that unrooting is just a matter of deleting those files.
So that, combined with the way that installing 2.2 would wipe the device anyway, means I'm really not worried about installing anything new on a rooted device. It's easy to unroot 2.1 if you want to, anyway.
Hi all, I hope you're not all tired of another noob posting up how-to questions. I come from a pretty solid background of writing modified firmware packages Motorola and Blackberry units, and writing custom themes for them both, so I am a bit familiar with the processes involved in rooting. Android is an entirely new beast though. I love it already, but I've also identified some things I'd love to be able to change. I've been reading everything I can in these forums for the past week, and I think I might be nearly ready to start diving into the root world. Yes, I've used the search a LOT Before I do root though, I wonder if you all might be able to add some insight into a few questions I haven't found the answers to thus far:
My rooting goals: remove the AT&T bloatware, possibly do a lag fix, and above all, do it the safest way possible. Baby steps first for me.
1) Rooting methods: Should I do the manual way, I found in that pdf guide on this site, the "GalaxyS_One-Click_Root_All_Models.zip" method, the mystery "update.zip" folder method, or the "one click root lag fix" method? Which is the safest and most tried and true for Stock 2.1 f/w, Baseband I897UCJH7? Also, what would be the best method to use if I wanted later to unroot?
2) Lag fixes: I've read that lag fixes can cause major problems when trying to undo them later on. Is there a lag fix that works well that is safer than others to load that can be removed easily? Are lag fixes even worth it?
3) Odin3: Am I correct in assuming that since I have JH7 that the most recent version of Odin is not capable of fully restoring my phone back to stock? I've been seeing posts from many people say that even using Odin, their phones get stuck during the revert process and cannot get back to stock. This is probably my biggest concern of all, in case I brick my phone. I've done that a LOT of times with Motorolas, and it's not a bit of fun trying to restore them.
Thanks very much in advance. Best wishes to all
The first piece of advice I have is make sure you have a cappi that you can get into recovery and download modes via the button combinations - if you can do this then you will be able to recover to a working configuration from just about any situation.
second, make sure you want to do this, because as you can get back to a "stock configuration" once you begin applying lag fixes or custom roms you will not likely be ever able to get back to your own stock configuration.
As for which rooting method - I have used and update zip and ryanza OCLF to root. Both of these methods are easy to unroot - at least until you begin applying lag fixes and/or custom roms.
If you are sure you want to move forward and root the very first thing you should do after rooting before you do any lag fixes or remove any bloat is get clockwork rom manager. Learn how to use rom manager and make a full nandroid backup of your phone before you do anything. If you have a good nandroid backup saved in a safe location then you can use this to get back as close as possible as you can to your own stock configuration later on.
Oden3 will get you back to a stock jf6 configuration. This will not be your stock configuration, but it is a working stock configuration.
Lag fixes do improve the lag in the file system some. However, before you play with any of them educate yourself as much as you can about the particular one you are going to try and use. I have applied both OCLF and voodoo and have been able to remove both of them. But if you don't follow the steps correctly you can have problems - after all with the lag fixes you are reformatting part or all of your data partition where the os is residing which is inherently risky. You can easily lose data and even soft brick your phone forcing you to use Oden3 to get back to a working state.
Lastly, I am running Cognition 2.2 beta 5 very successfully - and I do recommend it for anyone that has entered the rabbit hole of modifying this phone. And with my current config my phone is running so well that the lag fix is not needed for me anyway. My phone is running smooth and fast.
P.S. Just make sure you are not going to have any major regrets if things go wrong before you do anything at all, because any and all of these steps have some amount of risk associated with them. Make sure you are prepared for dealing with voiding your warranty and even though it is hard to brick this phone, it could still happen so be ready for that too should it happen.
i would agree, go with cognition 2.2. i only had my captivate for a day, and found it very easy to get it installed without any hassle.
Thanks for the info all. I've read about Cognition a fair bit and was wondering if I ought to go for it. What are the differences between it and the standrd Froyo leak?
A more pressing question: If I went to Cognition 2.2, would I be able to easily get the official release OTA and install it normally when/if it becomes available? Are there step-by-step guides out there for getting that release onto and off of the phone? I'd hate to get Cognition on there and find out that i couldn't easily get it back to a state where I could get the full deal on there. I've read some horror stories about just that lately...

If you are wanting to get OTA updates then I wouldn't even root your phone - while it is possible to still get OTA's after rooting, once you begin modding (lag fix, or custom rom) you oare increasing making your phone less and les compatible with any OTA available.
NOTE: I personally will not ever apply an OTA myself - but rather will wait for someone else to create a custom mod of any OTA feature I like - them donate that dev a few dollars and use their mod.
Im getting my cap this Friday, I was going to post the same thing OP. Looks like cog 2.2 is the way to go when i get it.
I've been doing a lot of reading regarding rooting the Nexus one and unlocking the bootloader etc. I wish not to unlock the bootloader at this stage (as you can't lock it again, and the fact that i'm gonna be playing around with my dad's phone and wouldnt want anything to happen to that)
Right now, the phone has stock 2.3.4 installed, which I believe needs to be downgraded to be rooted.
So I downloaded the FRG83 release.
Now is the following right/possible:
Flash the phone with FRG83 by going into the phone's recovery - so the phone is downgraded
Root the phone using the superoneclick method
Now the phone is rooted and I can flash it with any custom ROM eg, CyanogenMod 7 etc..?
Sorry if this has been covered earlier, however I tried my best to read as much as I could, however there were always a few more steps involved in the process which I thought could be left out
So would the above process be okay?
Thanks
You have to use the PASSIMG.ZIP method to downgrade.
I would just read the WIKI
http://forum.xda-developers.com/wik...des_&_Tutorials#Unroot_.2F_Restore_your_Nexus
Read the wiki. You said you been doing a lot of reading but still do not know how to root/downgrade from 2.3.4. That makes no sense.
The steps are there for a reason.
You don't know what you're doing but come to conclusion that you can skip/leave out steps. That is flat out stupid.
Thanks
Thanks baseballfanz Yeah I've read the wiki and I was going to use the PASSIMG method, hence downloaded the FRG83 file, but somewhere else I had read that you had to flash it to froyo then back upto gingerbread :/ hence was a bit confused.
The problem is there are too many threads about it. And there are a few tiny differences in all.
So I guess I have to flash down to froyo and then use superoneclick.
And after that, I can just flash any ROM from the forum?
Alubundy2010, mate I did read it all and understood it. However I still had a few questions. If you didnt wanna help, it would've been best to keep your mouth shut.
Thanks
It is clear you did not and still don't understand it.
Yeah probably not, hence why I posted asking for help in the first place. Just spent an hour trying to do it, but stuck at froyo for now till I do an official OTA update tmrw morning and have a stock unrooted phone, cus I honestly don't have the balls to brick my dad's phone. So not rooting till I'm 100% sure of what I'm doing.
Thanks a lot for all the amazing the help.
Wiki clearly says:
"Gingerbread 2.3.4 can be rooted only when downgraded to 2.3.3 or to Froyo, using PASSIMG method, which will wipe the phone"
And the link is given - landing you on the same page, a bit upwards. The link contains EVERYTHING needed to downgrade.
Moreover, the following sentence points you to a VERY simple guide, which says: when you downgrade, you root. Without any additional steps. And from that point you do whatever you want.
The main guideline of XDA should say - "if you don't know what you're doing - stay away from rooting until you do". Obviously you don't, and you don't seem willing to learn by reading the proper guides, even when pointed to.
And just to make sure you got it: you can't root the latest OS version. Which means, if you downgrade and wait for the OTA to upgrade you back to the latest version, you'll finish (again) without the ability to root, and this time also without the ability to downgrade. Not quite smart, yes? If you want to avoid unlocking the bootloader, that is.
Now that the phone is running froyo you can root.
You should also have gotten the ota notification basically as soon as the phone finished booting.

Oh well thanks for the help guys, and I did actually do all the reading that was required.
Oh and I also rooted the phone when it was on Froyo through the manual superboot process.
Is it possible to go back to the official at&t 2.2 update? I need to for a warranty exchange. If anyone could help, I would really appreciate it.

do not use the 3 button fix in that on gingerbread you will hard brick the device.
Okay. I'm rather noobish. What do I need to do to get back to stock? If there's a step-by-step I missed, I'm sorry. I do appreciate all the help.

Last question about this. I rooted using the fugu method for 2.3.3/4 and now i need to unroot because of data connectivity issues. Is there a special way to go about doing this?
Super one click its has an option for unroot.

why do you think root is causing data connectivity issues?
Because when I don't run my captivate with root, I get my 3g everywhere i normally can. I'm not sure why this happens, but on 2.2 stock I just lose it after a few hours of having root on, and since I was already rooted, it was instantly gone. I wish i knew why that happened on 2.2. But I am back on stock 2.2 and unrooted, just gotta wait for warranty crap now.

this doesnt make any sense. rooting doesnt change your network at all.
I understand that, but for some reason I don't get data connectivity when I am running root. Weird, I know.

Sequence is not causation. The two are 100% unrelated.
I'm runnin Pinnacle 1.3, but my wife's Cappy is stock but rooted, and her cell gets constant 3g. It must be something else.
I have to not that it only happened when it was 2.2, on the higher versions no problem.
