I am new to this and I found 3 ways to root my new SGS II:
1. using S2 root
2. using CF root
3. using superone click.
It seems that the no 1 way is the easiest.
Q1: Which is the safest one
Q2: Once I install an insecure kernel will I get updates via Kies
Q3: I have the folowing PDA: KF3, PHONE: KE7, CSK: KE1(COA). Should I use any specific CSC version or the generic stock would be enough (when I flash back the original kernel). This is something that I do not understand and I performed an extensive google search, but I am very confused. What is the relevance of CSC, as i see on this post http://forum.xda-developers.com/showthread.php?t=1075278 there are a lot original versions but mine (COA) is not among them. What to choose to flash back the stock version or my COA version.
Please help...
If you are flashing a kernel ignore csc version, that's not related, the easiest way is to flash the correct cf root kernel, in this case kf3, ignore the region code, then grab the correct stock kernel from that thread.
You don't need to put the stock kernel back, and if you do you will lose cmw recovery and the ability to use the cwm manager app that comes with cf root.
Csc is apn settings and bundled apps, generally you can use any rom with any csc but you can always manually put in your apn settings if they are missing

1- IMO CF root is the easiest. All are safe, my recommendation would be CF.
2- Kies updates have nothing to do with Kernels. As long as you are on Stock Official ROM's, you will receive updates.
3- Your firmware is KF3. CSC is region specific settings, like Keyboard language, APN's, SIM services etc etc. It's not that much important. I'd advice you to not change CSC anyway.
Regards.
If you are unsure about firmware and csc and only want to root then root with cf-root and dont touch anything else until you are sure about what your doing.The last thing you need to do is rush in and brick your phone.CF-Root is quick and easy.

heres a link for the root kernel and odin.Yourll find the zip file towards the bottom of the page.
i suppose you will need this CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4
from http://forum.xda-developers.com/showthread.php?t=1103399
After using this im not very clear if you need to flash anything after or not?
will you get the warning mark after rebooting?
You don't need CF-Kernel to root the phone now.
All you need is to just flash any rooted kernel.
I recommend using speedmod kernel by hardcore. Most people who flash to CF-Kernel are going to switch to something else anyways, so you might as well skip that extra step and go to the kernel that you would recommend best.
The easiest is to just download your favorite kernel, then flash it by using odin. DO NOT REPARTITION THE PHONE.

Yes, I get the yelow triangle. There is a way to get rid of it: flash the original kernel back. You will not loose root.
CF root
As I understand I should use the CF root way and flash the folowing CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4. I still have some questions:
1. Will I still get updates via Kies?
2. Will my phone be wiped after flashing this - I understand NO - right?
3. To remove the yellow triangle I should reflash the original kernel (XWKF3 Stock Kernel: http://www.multiupload.com/27Q9LQEB94) from here: http://forum.xda-developers.com/showthread.php?t=1075278 ?
Sorry for so many questions but as in my job I have to check twice before doing it.

Sorry for the ignorant question but what is the difference between speedmod kernel and cf-kernel?
If i understand this on simple terms CF-KERNEL is kept to a basic minimum?
where can we get the speedmod kernel?
[KERNEL] SpeedMod SGS2 [K1-T27 CWM4 CIFS ROOT]
Yes, CF-Kernel is pretty much the same as stock except that it has the stuff required for root, and addition of Clockwork Recovery and Clockwork Recovery Application.
Other kernels have tweaks such as overclocking, undervolting, and extras.
I don't recommend kernels that have overclocking or undervolting, but that's just my own preference.
I appreciate these features as I am in ninphetamine. With undervolting you're able to save battery. But as you said...these are personal preferences.
thank you so much for the info. Im particularly concerned with battery life hence choosing to root in the first place.

Hey everyone,
First post, n00b question - please be gentle.
First, I'll start with a positive. I have come from using an iPhone, and I was quiet comfortable with jailbreaking and cydia. I now have a Samsung Galaxy S 2 / II (GT-I9100T). I am from Australia, and on the Telstra network. Whoever is in the same boat would know it is quiet an adjustment, but you can root! (if you wanted to know).
I followed this persons 3 part guide and with sucess:
I cannot post the link but it is on YouTube and the video title is:
How To Root The Samsung Galaxy S II - Part 1
How To Root The Samsung Galaxy S II - Part 2
How To Root The Samsung Galaxy S II - Part 3
Username is mattj101101
I had Android 2.3.3 installed.
Second part is a question, is there any debranding roms / kernals that is ok for the GT-I9100T? I have tried the *#272*IMEI# but it only had 'Preconfig - TEL'
My phones info:
PDA: 19100TDVKF4
PHONE: I9100TDVKF2
CSC: I9100TTELFK3
My Kernal version, after the root is 2.6.35.7-I9100XWKDD-CL161513root<insertATsymbol>DELL103 #2
Hopefully with these answers I can help other fellow people out with this particular model (that are sold in Australia). Also if someone has the stock Telstra rom for re-flashing (if needed for warrenty) please point me in the right direction.
Thank-you.
Hey,
Ive got the GT-I9100T from Vodafone (both can run on the telstra bandwidth now ) and have had no issues flashing most roms. Only thing you may notice is the new modems aren't as good as the stock ones you currently have, so you may need to reflash the original modem through odin to get the best support.
Before you do flash though, make sure you back up your /efs folder, it contains the bin files for your IMEI for your phone, and people have reported flashing a rom can change that, so beware! also, before you do flash, try find the stock telstra rom for your phone incase you need to reflash. There are a few threads about it all, so good luck
The i9100T can use i9100 roms, but it will change the product code to i9100.
Easiest way to root is using CF-root, match the part of the version number in bold "PDA: 19100TDVKF4"
My phones info:
PDA: The rom/kernel
PHONE: The modem/radio, responsable for signal quality and speed, you dont need to match this to rom version, and the best way to find a good one is to test different ones.
CSC: APN settings and bundles apps, no need to match this, but if you do chose to all you may have todo is enter your APN settings for internet and MMS manually.
You can flash any rom onto any SGS2 via odin, see this guide, that will debrand etc.
Also, you rooted using a very old insecure kernel, people have had random reboots with that one, I suggest you flash back your stock kernel (you will keep root) or flash a version of cf-root (you will gain clockworkmod recovery, a way to flash roms/etc from your phone, and nandroid, a whole phone backup system, like snapshots)
I would recommend flashing DarkyRom2 on your S2. Runs fast, stable and great battery life. It roots your phone as well and changes your kernel to SuperCore which has a lot of optimisations.
Instructions:
Since you're not rooted (stock firmware/kernel)
1. Flash SuperCore_1.7.tar with Odin (put in PDA and do NOT tick repartition)
2. Get DarkyROM2 Tool and Superuser from market
3. Upload DarkyROM2_XXKH3_Base_R2.zip to SD-Card (INTERNAL)
4. Open DarkyROM2 tool. Accept SuperUser access request notification (this confirms you are rooted.
4. Under the DarkyRom tab, be sure "Wipe User data" is selected AND "INSTALL MODEM" is NOT SELECTED. (this will wipe everything from your phone but keep your stock KF4 modem. Any other modem causes signal problems for our I-9100T. )
5. No need to select "Install Kernel" Since SuperCore 1.7 is already installed.
5. Go back to the General Tab and use "Flash/Install File from SDCARD" to browse to and install DarkyROM2_XXKH3_Base_R2.zip
6. Wait for the phone to reboot and flash the new firmware
Get the files here:
http://www.darkyrom.com/community/index.php?threads/rom-cwm-sgs2-darkyrom2-kh3-base.4950/
I modified the instructions given on that link and posted it above for you since it's a little different for our I-9100T phones.

Interestingly, I just purchased a SGS2 here in Thailand (I'm also an Aussie) and the model of the phone is GT-I9100T.
Unfortunately I cannot seem to find a KL2 kernel for CF-Root to patch it with... any suggestions?
Also, the site that held all the OEM kernels (MultiUpload) for download is now showing a "Shut down by the FBI" logo : )
As long as you're certain you've got a I9100T, use the KL1 CFRoot kernel. Will work fine.

My phone details are as follows:
Model: GT-I9100T
Android: 2.3.6
Baseband: I9100TDCKL1
Kernel: 2.6.35.7-I9100TDCKL2-CL767350 [email protected]#2
Build: GINGERBREAD.DCKL2
This is not an Aussie phone such as the Telstra I9100T that I see spoken about.
I purchased this phone here in Thailand 3 days ago and I have a few questions.
1. Is there a way to backup the original kernel before rooting?
2. Will the KL1 kernal make me lose things such as Thai language options etc?
3. Any way to restore the KL2 kernel in the future?
Thanks for taking the time to reply!

1) Doubt it. And the only link for DCKL2/Thailand in Intra's official firmware thread is dead as it was MegaUpload, and he more than likely won't have a backup (you could always ask him tho). Search around elsewhere online, you might find a copy of this kernel somewhere.
2) I don't know for certain, but I don't think so. I would have thought something like language would be more firmware-related.
3) Refer to 1) I don't see why you'd need to ? In order to get warranty service from Samsung, all you'd need to do is flash the most recent firmware available for your phone (for all they know you could easily have got this from an OTA update via Kies), do a factory reset/make sure there's no apps left on your phone that could tip off whomever repairs it that the phone was rooted, and use a jig to reset the flash counter. Obviously there are no rolled gold guarantees with getting warranty service once you've voided same by rooting the phone/running non-stock firmware firmware on it, tho.

I was just worried it might stop future updates to ICS or similar via Kies.
At least I think I've managed to find another copy of the latest kernal on a site other than MegaUpload...
It's at 50% and counting : )
3) Refer to 1) I don't see why you'd need to ? In order to get warranty service
Running a CFRoot kernel over stock firmware should still allow you to receive OTA updates via Kies. If you find it doesn't, simply use Checkfus (search for it on here), it allows you to find/download the latest firmware for your phone/country that you'd normally get via Kies.
Really ? Cool Might wanna post a linky to your source over in Intra's thread. I'm sure there will be other people who might need it at some stage.

Ok so would you believe...
I ran the guide from Intra.
Installed an insecure ROM and then ran SuperOneClick and was rooted.

Yeah, if you flash an original (unrooted) kernel over your rooted kernel you'll lose root.
There's a procedure for removing the yellow warning triangle at boot in the CFRoot thread & also retaining root, but I found it too fiddly when I first rooted my phone so I simply bought a jig & did it that way.
I can't speak for anything to do with SuperOneClick as I've never used it.

As I said, I have no idea whatsoever about anything to do with SuperOneClick. If you want a rooted phone minus the yellow warning triangle at boot without fiddling around, root it with a CFRoot kernel, buy a $3 jig from eBay, done.
So far as Kies not working, you could try uninstalling/reinstalling Kies, or simply use Checkfus as I've said previously. Me, I'd use Checkfus. Quick, easy & like the paragraph above, no fiddling around.
Edit to add - Yes, obviously Kies won't work if you're running an "insecure rom" as per your post above. I presume you mean a custom rom you found somewhere on here or elsewhere ? One of my earlier posts did say Kies should (not always) work if you're running a rooted kernel over a stock Samsung rom. If you're running a non-stock rom Kies won't work.

Ditch Kies there is a better alternative out there. MyphoneExplore, do a seach via google. You'll also need to get the app client software from the android market. I use it to synch my work Outlook Calendar to my phone. You can also back up your contacts, sms and call records.

Edit: I tried CF-Root KL3 (wanted KL2) and it seems fine so far.
I have root and everything else seems the same (Thai language support etc.)
I'll keep you posted : )
Thanks for taking the time to deal with my issues!
Hope I can do the same for some others on this Forum in the future.
I'd not heard of Checkfus so I'll give that a try, thanks : )
There's no CF-Root to match my phone exactly but I guess there's nothing to lose now by trying something close : P
I ordered the jig almost a week before getting the phone but it seems the postage to Thailand is sloooow.
I'm running a stock ROM and unrooted but Kies is still misbehaving.

Something may have borked so far as the CSC goes (which tells Kies, the Market, etc where you are). I did say you should be able to use Kies, you're not the first person to have problems with it after rooting
Personally speaking, I've never used Kies & almost certainly won't use it. Ever. Custom roms/kernels are a piece of you know what to flash via CWRecovery (or Odin for that matter), and official firmware updates are easy to get with Checkfus & flash via Odin if I ever have to go down that path for warranty purposes or whatever.
Kies is a truly awful piece of software

Hi All,
I'm getting my SII tomorrow on the O2 UK network.
I've read the "[17.08.2011][CF-Root v4.1] KE2/7/8, KF1/2/3/4, KG1/2/3/5/6/7, KH1/3 - su+bb+CWM4" thread and feel confident in rooting the new device and fully understand the point of rooting, however I have a few Q's.
"Firmware" and "Kernel" are completely different entities?
i.e the kernel is the operation system between the software and hardware?
and the Firmware is what as opposed to the kernel?
Is the "XWKDD_insecure.tar" a generic kernel just to gain root access?
I want to leave the "branded O2" Firmware as is and just want root access.
So am I correct to assume the following!!
Using ODIN and super one click 2.1.1 and the correct "Kernel" dependent upon the information from "About" I can flash the kernel, super one click and have root access with O2 branding intact?
Would I then need to re-flash a stock kernel to have the phone like out of the box?
Hope someone can clarify...
Thank You
Find out which kernel matches your's and then flash it using odin. You need to reflash the secured kernel in order to remove the yellow triangle at boot. If you have an USB Jig this step is optional

Kernel is the core between OS and Hardware .
Firmware is the whole package kernel OS modem android aps etc .

Modified yes XWKDD is well out of date

Well i would just follow the instructions in the CWM and root post dont see superonclick involved in that .Oh i see you are using the method that states on page one it has been replaced is now defunct .

So basically all I need is the correct CF-Root Kernel and odin and all is good..

Hi everyone,
Im getting a sgs2 next week (finally), and want to pimp it up as soon as it is in my hands. I wanna check with you guys if I understood everything right, since this is gonna be my first android phone.
Let say I choose to flash with the latest original firmare, that would be XXKI4 or XXKI8. I get it here.
I also want it rooted. So Im supposed to flash XXKI4 first, then root it using S2 Root v1.5.1 or CF-Root 4.4 but, which one? S2 Root requires the phone to be flashed with an "insecure kernel" prior rooting. Do i need the insecure kernel from XXKI4, or from my previous firmware? After the rooting, i need to reflash the secure kernel (cause its safer and removes a yellow triangle)? So if I understand, each firmware has a kernel. To be root, you need the kernel to be unsecured.
And about the flash counter... are the latest firmwares coming (ironicly) with the old bootloader, and that means the counter won't be raised o easily set to zero afterwards?
So first i need to flash the firmware i want, then secure kernel of that one, then root, and then secure back?
Lots ob doubts, thanks for your time
I recommend CF-Root even if also SOC works well.
This because CF-Root is one step and done, while SOC asks multiple steps, and the not experienced android users got more chances to screw up and end up with a semi/full briked phone.
Read carefully the CF-Root instructions, dont forget anything in the instructions and in about 20 seconds you have your phone rooted.
Be sure to have installed Samsung KIES (this install the official samsung drivers) but to NOT have it running in background when you use odin (kill the kies process tree), because kies dosnt like ODIN and it blocks it at half flashing (with chance of semibrick the phone).
Also DONT ever never use Rom Manager, SII is not compatible with rom manager, a lot of ppl got semi/full briked phone by using it.
No need to use insecure/secure kernels with cf-root (that's why, only 1 step).
About the original firmwares, the ones in Intratech thread if im not wrong (can be, i didnt really checked deep) are with old bootloader, so yes, you can go back to 0 with a usb jig.
Another and last thing, be sure you have the 9100 international, NOT the AT&T or the 9100G/M that need other files to work.

Just in addition to rembrandtlnx's good and correct reply:
1. Read the first post of Intratech's thread => http://forum.xda-developers.com/showthread.php?t=1075278.
Please read the whole post and take your time to understand it.
2. Do the steps described there to flash XXKI4 to your phone.
It is non-wipe version with old bootloader (as Intratech said ... it's true).
And this will never increase the counter, as it count only custom or insecure kernels (such as CF-Root).
3. If you want to root your phone, the easiest way to do is to flash the corresponding CF-Root kernel, which is XXKI4 v4.4.
Please stick to Chainfire's description of his first post in his thread => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root.
This will increase the counter and give you the yellow triangle when booting your phone.
4. If you want to get rid of the yellow triangle, please read Chainfire's guide in his second post.
This will not increase the counter any more, as you will flash the original / stock kernel and use CWM to re-flash the CF-Root kernel (zImage file).
5. To reset the counter, rembrandtlnx told you how to do it.
I don't bother about the counter. It's just a number on my phone.
Good luck, and don't forget to backup all important data on your phone before flashing !
Hi,
I am with AT&T in the US and recently bought the Galaxy S2. My device happens to be a French version. My firmware is
PDA: KG1 / PHONE: KG1 / CSC: KG2 (XEF). It's 2.3.3.
I'm not happy with my HSPA+ data connection. While streaming online radio in moving car, it would cut out and constantly buffer. Seems like the data stream is not reconnecting quickly enough whenever there's handoff. This has never happened in my old webOS Pre Plus. The streaming on the same route that I drive daily on the Pre Plus was never an issue.
I don't want to mess with flashing to a different ROM (yet), but is it possible to just replace/flash the baseband only? Perhaps I can try the official ATT baseband? I did a search and am overwhelmed with the amount of info on XDA. I appreciate you help. Thank you.

You will need to root it to be able to install different modems using CWM recovery or you can use Odin to do it with out root if you can find modem packaged for Odin, as for the AT&T modem while it will work okay for data your call quality will be terrible so it is not really an option for an international version SGS2.
jhernand1102 - Thanks for your quick reply! I've done some flashing before on other devices, so I'm not totally unfamiliar with the process. So it is possible to install a different modem without completely flashing to a different ROM? I see that you're in the US. Can you suggest a modem? What do you use?

Yes, it is possible to flash another modem file to your phone.
The easiest way of doing so is to flash it as zip file via CWM.
But you can also flash the modem.bin file (extract the zip file first) via Odin (in PHONE section).
Here are two links to the latest modem files:
1. => http://forum.xda-developers.com/showthread.php?t=1277593&highlight=Modem+XXKI3
But you need CWM to flash this Modem zip files.
2. => http://forum.xda-developers.com/showpost.php?p=17967764&postcount=5
Same here, but you can extract the Modem.bin file out of the zip file and flash it using (Phone section in) Odin.
Good luck!

Thanks It_ler. I think your links were truncated, and as a result, it's not coming up. I have Odin on my computer. In your view, is it better to use Odin or CWM?
JackTheMan18 - I don't have issues with voice calls on ATT, but it's the HSPA+ connection when streaming is what I'm not happy about.

Sorry about the truncated links - now repaired.
Searched myself in this forum and while copying&pasting ... something went wrong.
I don't have a personal prefer ... Odin or CWM ?!
If your phone is rooted and you already have CWM, it is the easiest way to flash modem zip file using CWM.
As I am running on CF-Root kernel which has installed CWM Manager app, I would flash the modem zip file using CWM.
But normally, I choose my ROM and modem and CSC before flashing ... and then I flash all the files I want together at once via Odin.
So, it's up to you !

It_ler - Thank you so much! You've been incredibly helpful! Since you are so knowledgeable, I hope you might be able to answer this follow up question. As I indicated, I'm stuck on the French 2.3.3 ROM.
1. Can I just flash a 2.3.4 or 2.3.5 stock ROM without rooting but using ODIN? Will that be a clean wipe or will it just upgrade and keep all my app and settings?
2. Will doing so prevent Kies from offering me future updates? I don't care about CSC, in fact, half the French customizations on my unit don't work here in the US. My first SGS2 unit that was defective was an UK version (I assume so because it came installed with the BBC app).
3. What's a good stock ROM to put on?
You are awesome!

I thought that you already knew about the basics, but here they are:
a) To get familiar with flashing ROMs / kernels / etc., find official firmwares, stock kernels, etc. and to learn the "manual" rooting method, read the first post of Intratech's thread => http://forum.xda-developers.com/showthread.php?t=1075278.
Official firmwares are in the second post, and Frankenstein versions (which can be combined with any other modem and/or CSC) are in the third post.
Every ROM is non-wipe - except Intratech has explicitly written that it is a "wipe" version.
Flashing is by using Odin and does not require root.
But Intratech has added a Quick Rooting Guide, just in case you need it.
b) To find the easiest way of rooting, please stick to Chainfire's CF-Root thread => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root.
There you learn to root your phone and get ClockWorkMod (CWM) Manager app with CWM recovery mode, system backup&recovery feature, flashing other kernels and zip files, etc..
Nothing to bother. I just flashed CF-Root kernel because it is so easy and I wanted to be able to backup my system.
Now I can answer your questions:
1. Yes, stick to Intratech's description and use a non-wipe ROM to flash using Odin (PDA section).
2. As KIES will only recognize and update official/stock ROMs available in/for your region, flashing any other ROM or kernel will prevent KIES from doing so.
But I don't care too. Flashing with Odin is very easy, fast and as stable as the ROM you are flashing.
I stick to the official/stock ROMs provided by Intratech - they have always doing fine for me.
3. I recommend the latest Frankenstein ROM, which is actually XWKJ1 (which I am running now).
It is Android 2.3.5, good balance between performance and battery life, excellent modem (XXKI3) and you can combine it with any other modem or CSC for your region and/or provider.
Just put this ROM in PDA, your modem in PHONE and your CSC in CSC section of Odin and flash all at once.
If you will find the descriptions and/or files helpful, please remember to push the Thanks button for Intratech and Chainfire, as they both do a great job for all of us.
Wow! It_ler - thank you for all the great info! Just a quick question. Does XWKJ1 have any issues. For example, does google video chat still work?

I did not recognize any issue yet.
But Google Talk is without Video chat.
You can replace it with a leaked Talk app with Video chat enabled.
Just have a look here => http://www.redmondpie.com/how-to-install-google-talk-1.3-with-video-chat-on-any-android-phone-root-only/
But you have to use CWM recovery mode to install it.
I did not use ROM-Manager as described, I used CWM Manager (of CF-Root) to install it.
Please remember to wipe cache partition and dalvik cache as described.
And make a system backup before ... Just in case ...
Good luck!

I was able to install XXKI3 radio. It didn't make a difference. Turns out that I needed to disable fast dormancy. The data connection seems more stable. I will have to test it out further on Monday. In regards to Frankensteinrom XWKJ1, is it already rooted?
If I discover problem on my end with that Frankensteinrom, can I flash back to official ROM without wipe? Thanks!

Neither official nor Frankenstein versions are rooted.
If you want to Root, follow the instructions of Intratech or Chainfire to do so.
You can flash back to an Official ROM.
If you want to flash without wipe, you have to use a non-wipe version.
So, no problem with most of the versions from Intratech's thread.

Hello,
After reading a lot and asking for advice/thoughts/suggestions, I have decided to root my phone to install a new kernel on stock firmware to attain better battery life and performance. I like the stability of stock roms, and it was pointed out to me that any other rom will be unstable to some extent (here: http://forum.xda-developers.com/showthread.php?p=21354863#post21354863)
First, my phone info:
Model: GT-I9100
Android Version: 2.3.4
Baseband Version: I9100XXKI1
Kernel Version: 2.6.35.7-I9100XWKI4-CL575468
[email protected] #2
Build number: GINGERBREAD.XWKI4
At this point I think I will flash this firmware:
Code:
XILA2
Firmware info
PDA:XILA2
PHONE: XWKI1
Date: 12/01/2012
Android 2.3.6
ITV (Italy):http://www.multiupload.com/DCYIJJ47I5
XILA2 Stock Kernel: http://www.multiupload.com/U7GK3FPHXF
Password: i[email protected]
Source: http://forum.xda-developers.com/showthread.php?t=1075278
And I will also flash whichever is the most updated version of SpeedMod
Question 1) Is this possible?
Yes. ~MistahBungle
Question 2) Would this be stable, as claimed by http://forum.xda-developers.com/showpost.php?p=21493150&postcount=14
yes ~MistahBungle
Question 3) Is there anything special about the country specific versions of the firmware on http://forum.xda-developers.com/showthread.php?t=1075278 ?
I.E. I am in Russia, so do I have to install the Russian one? Or can I install XX, etc.
(question was also asked here: http://forum.xda-developers.com/showpost.php?p=21564834&postcount=1)
no~MistahBungle
4) Is there any way to save the apps I have now before rooting?
Not really before rooting, use speedmod to root your current rom then use titanium backup to backup *USER* apps ~veyka
5) Speedmod says that it includes root. Does that mean that I can just, using odin, skip the step for CF root, and install speedmod?
Yes ~http://touristinparadise.blogspot.com/2010/11/samsung-galaxy-s-how-to-install.html
6) Should I flash XILA2 first or Speedmod first?
Speedmod
6b) If I flash speedmod first to get root, then XILA2, do I loose SM?
when you flash the rom it will come with its own kernel, that will replace speedmod, just flash speedmod again over the top, you wont lose the rom ~veyka
7) At the end of the process below, will I still have the yellow triangle (theoretically?)
Yes, easiest way to get rid of it and keep speedmod/CWM is to buy a USB jig. ~veyka
8) On the Intratech thread, as quoted in the code box above, there are 2 links for the firmware. What is the difference? I asked the question on that thread, but have not gotten a response yet. Search is down.
2nd is full firmware
9) Where can I get ADB codes to use for zergRush?
Kies ~It_ler
10) At what points along this crazy process should I be wiping what?
If I am going to flash the kernel and/or firmware, I understand that there are many steps to take which have been outlined 100 times. I would like to list them below to make sure I have them right. If I make a mistake, can someone please comment to let me know?
1) Root phone using ZergRush
2) Nandroid Backup
3) I understand that I need to backup my EFS folder, which I plan on doing using ktool
http://forum.xda-developers.com/showthread.php?t=1314719
4) Download Mobile Odin
5) Backup userapps using Ti
6) Use smsbackup+ to backup sms to gmail (doesnt need root but useful app anyway)
7) Flash XILA2 using EverRoot on Mobile Odin
8) Flash SpeedMod on MO
9) nandroid backup again
I appreciate your help and time. Any helpful answer gets “thanks”!
1) Yes.
2) Yes. Absolutely. No reason why it wouldn't be "stable", tho obviously your experience with any given rom/kernel may vary/differ from my experience of same.
3) No
4) The best backup solution for non-rooted phones I could find was MyBackup Pro, but in all honesty you're unlikely to have anything go wrong rooting your phone with CF Root. Best way to go would be to root your phone, then backup using Ti/do a Nandroid backup in CW Recovery before you do anything else, then flash any rom/kernel you want after that. This will give you a backup of your phone pretty much in its "original state" (minus your original kernel tho, obviously) you can go back to if you do find you have problems installing a new rom/if the rom doesn't work as well as you want it to.
You've done well with the steps you've outlined to get to where you want to go, they're very well planned/thought out If you follow those, I'd be surprised if you have any problems.
Edit - bit more detail
Thank you very much!
I just read that speedmod automatically installs root. I assume this means that I can use odin install speedmod on an unrooted phone?
If so, where does that leave my EFS folder?
Edit: Yes I can.
Might want to ask that one on the Speedmod thread. I used Speedmod briefly a while back but my phone was already rooted so I have no idea. I would have thought the first page of the thread would be pretty clear about any instructions.
The EFS thing is pretty simple, root your phone & use Hellcat's kTool to make a backup, store a copy of the backup on your external SD card & a copy on your PC/elsewhere.

Why did you switch from speedmod?
Doesn't work with CM/Miui There weren't enough pluses with the other roms I'd tried w/Speedmod to warrant sticking with the kernel. So I went back to Miui w/Siyah.

Ok, nearly everything is said.
Just a "small" additional suggestion:
There is a description of how to get rid of yellow triangle after flashing an insecure kernel in Intratech's first post of his Official Firmware thread, in Chainfire's second post of his CF-Root thread, and there is another way of preventing the yellow triangle and the incrementation of the binary counter (other than using a USB Jig):
As you still have XWKI4 stock ROM, you are able to root your phone using the zergRush exploit. (You can find a short description in Intratech's first post of his Official Firmware thread and a link to the corresponding zergRush thread.)
Then you can buy (Chainfire's) Mobile Odin from the Market.
Using the paid version of Mobile Odin and having a rooted phone, you are able to flash stock ROMs (such as XILA2) with the EverRoot option, which allows you to remain root - without the yellow triangle and without an incremented binary counter.
With Mobile Odin you can easily flash custom kernels (such as SpeedMod) as well, after flashing the stock ROM you want to have (XILA2).
Good luck and don't forget to make a backup (as soon as you have rooted your phone) !
That will cost about the same as me getting a jig, and i dont have to worry about it getting lost in the mail
On the intratech thread there are 2 links for la2, which one should I be flashing?

Feel free to use a USB Jig - as long as you have the old bootloader.
I recommend to flash Frankenstein ROMs, as they are same as stock ROMs (with old bootloader) and build to be combined with any Modem and/or CSC file.

If you have the samsung phone drivers installed, you have the adb drivers, if not there is a copy in my 4shared (link in my sig, 4icon)

How do I do a nandroid backup without having cw?
so i did something stupid, i think. so far i dont see any lasting damage, i dont think.
i went into the market and installed rom manager, then flashed clockwork mod, then went to do a backup but it failed because it couldnt find an update or something. i just rebooted, and my phone turned on, looks fine. how can i a) get rid of that, and b) backup my phone?

Uninstall rom manager first, it was what caused the problem,
sgs2 does not like or is incompatible with certain functions of rom manager.
download and flash this file using odin for cwm standalone.
Old - 4.0.1.5: http://www.multiupload.com/GEXTWB05E0 (md5: aa3929770791364ddfdc8ca23db2203f)
then go into cwm and make a back up.
