Are you talkin about the unrooting section of this thread?
http://forum.xda-developers.com/showthread.php?t=1088494

you need to flash a recovery via fastboot, go into recovery and wipe the phone, flash the latest cyanogenmod, and flash the latest gapps.
there are a bunch of guides in the nexus s general forums, and in the development forums.

See this is why I hate one click root methods. When something goes wrong you don't know how to fix it.
Flash a recovery using fastboot. Then wipe data factory reset, wipe cache, wipe dalvic cache. Mount storage and transfer the rom you want to flash. Then choose install from zip. Then reboot and you should be up a d running.

Skyrocket stuck on startup after flashing rom

I just flashed the MXH Superlite rom (http://forum.xda-developers.com/showthread.php?t=1525638&page=43) as per the instructions onto my skyrocket i727. Wiped it, cleared dalvik cache and formatted the system. Installed the recommended modem followed by the rom, and the phone was stuck on the Samsung startup screen. I've recovered using a backup, but I really want to install this rom. Whats the problem here?

Try booting into cwm and re wipe and reinstall, try just the rom this time

Your best bet is review the MHX-SUPERLITE thread in the Development section... and ask there. This rom is on my "next to flash" list as well...

I flashed it on a friends sr no issues but it progressively got slower and crawled after first reboot it was odd.

You need to wipe everything a couple times before flashing on these phones and sometimes install 2-3 times too
Wipe data, cache partition, and delvik 3x's each and install twice or something

I've never once installed multiple times multiple wipes yes but multiple installs????

[Q] Stuck on "Performing factory data reset"

I removed the ICS build and use ODIN to return back to stock build.
Still having some problem so i did a data reset. It keep getting stuck there and i already done it three times.
Any suggestions?

So you flashed GB stock.tar through Odin? Do you mean factory/data reset in clockwork recovery? Flashing back to stock should take away your root so you would have to flash CWM again, make a nandroid backup, and flash superuser zip again.
What problems where you having before and after the ICS build?
Explain a bit further exactly what you did.

I installed STOCK Tar using ODIN.
It is booting up fine except i keep getting errors like "android.process.acore" has stopped unexpectedly. Most of the android apps is not working, like phone, contacts, calendars, etc.
I try to do a factory reset and it keep stopping halfway and hangs.

Your going to have to flash the kj2 modem. I had the same problem. I saw that the ucalc4 was still there, its on its own partition so it doesn't get changed when you flash stock tar. What I did...
1. Flash cwm in Odin
2. Boot into cwm (do backup)
3. Flash kj2 modem (I did it twice)
4. Reboot
5. Check baseband (should be uckj2)
This made the FC's go away. It seemed to me that the stock tar doesn't like that baseband, I can't explain why though. Didn't make sense to me but I fixed it. Also I found the ICS leak doesn't like stock recovery. Fyi

Little bit lost here.
I already flash it twice using ODIN and using the uckj2 build.

Build is one thing, baseband is different. When you flash stock your build will be uckj2, you say your on it. OK good. Now check your baseband, will probably still be the ICS baseband ucalc4, that is your modem. You need to flash the uckj2 modem in cwm. http://forum.xda-developers.com/showthread.php?p=20157930
Once you flash that your baseband will be uckj2. That should fix your fc's. Did for me. If not, you may need to try something else which I will explain if need be that will clean things up.

OK. What you need to do then is clean things up. There are two ways that I use but I prefer #1.
1. Flash darkside superwipe in cwm. Do a battery pull. Go into Odin and flash k0nanes tar.
OR
2. Flash stock recovery. Wipe data/factory reset. Do a battery pull. Go into Odin and flash k0nanes tar.
Then you can cwm, root, flash anything you want.

Everything is fine now.

Glad to hear that. I swear by darkside between ROMS.

Yah....Darkside.Wipe is killer. Glad to hear your back in action. It is confusing at first getting OS version, kernel, and modem all strait. It is a good learning experience.
Sent from my SAMSUNG-SGH-I727 using xda premium

basically those fc's were becuz the partition table needs to be reset after flashing ics to go back to gb. Darkside does this.

I would just go back to 5.8. It's much better for me. Plus it works far better for ics builds. But yeah, you can use your buttons again for that old ass version you got now

Can you get back to recovery to flash a new ROM?
I have flashed many ROMS recently to try them out and also had a similar issue with one or two of them.
On my Note 2 I hold power, home and volume up to cycle power and get back to recovery and simply flash a new ROM, presto...

everytime i.flash a rom. i format everything. it might be you flashed a corupt file. redownload reflash

Not sure what is going on but here is how I flash a ROM from recovery and so far so good.
Copy rom file to external sd card in phone.
Do a full factory wipe, cache and dalvik.
Install rom.
Install Gapps if necessary or desired.
Wipe cache and dalvik again.
Reboot
Note that some roms will give you a recommended list of what to wipe if doing a new install or upgrade of that rom, if such instructions exist its best to follow those instead but the above has worked for me for a while now.

That's what is advised to do before flashing a completely different ROM anyway by some. From recovery, flash the ROM again, and if the ROM is not corrupted (check md5 or whatever comes with it), you should be good to go.

-wipe dalvik cache
-format /system
-install superuser
-install PA 3.99
-install GApps 4.3
-reboot system
-let sit for 10-15 minutes
-set up with wizard
everything is fine from here until i go to restart, it makes it to the first Samsung screen, then just sits black screened. no problem rebooting to recovery. will not boot again until i re-do all steps above. problem persists. Anyone? Bueller?

Once or twice while doing this a million times, when I went to reboot system from CWM it said superuser was not installed, so I just added that to the process to keep that from popping up again.

Skip the superuser step or do it last. Use a newer recovery. Wipes...flash rom..flash gapps..reboot...let it sit for a bit...set up your phone. If you find you are not rooted..then boot to recovery and flash superuser. You're doing all the wipes then trying to flash root files without an OS. And...if you have been flashing for a while and flashing alot...maybe its time to Odin back to stock. Read what Vincom posted as well as his other stickies.
