[Q] No more able to root the SGS (official Froyo - Z4Root)

Hi all,
my problem is that Z4Root doesn't work any more. It seems to work... reboot the phone... and nothing change.
This happen after I've unrooted the phone and a friend of mine applied the root procedure from OCLF.
I wiped all more than one time but Z4Root and SuperOneClick also doesn't work.
Any idea to solve this? If I flash an Eclair official ROM I'll be able to update it to Froyo via Kies?
Thanks in advance.

[Q] unrooting issues

hey all,
im having some issues with unrooting my I9000
i had a rooted 2.1 eclair device wich i updated to 2.2 now i cant root or unroot it anymore. tried aplying the update.zip wich gave me signature verification error and the one click root/unroot doenst even do anything (unless startup then)
do i need to reset the original firmware back again or is there a solution ?

Did you root it again after you get 2.2? that's why you wanna unroot?? My understanding is that once you flash the firmware, the root is gone too.

nope my phone was rooted when i updated it but after the update apps said that it wasnt rooted anymore, so i tried rooting it again, that didnt work and the kernel version says root so that why i want to unroot, i want root 2.2

solved
installed SuperOneClick root and it worked thanks anyways

[Q] How to undo froyo 2.2 upgrade

Hi everyone,
I have upgraded my Samsung Galaxy S GT-I9000 from Eclair 2.1 to Froyo 2.2 via Samsung Kies. I have used Ryan's Z4root to root it which was success. Everything was fine until here. When I tried to fix the lag using the update.zip, it failed saying 'file verification failed' (somthing of this sort). I chekced on different forums and found that there isn't any update.zip file to fix lag on 2.2 (am I right?).
If there is one, could someone point me in that direction. If there isn't, how can I undo 2.2 and rollback to 2.1 so that I can root it and fix the lag.
Please ask if you need any further details regarding my phone or the process I used to root and fix the lag.
Thanks in advance.

Superoneclick worked for me on 2.2 and 2.2.1 if you just need to root the phone.

Thanks for your reply but I have already rooted my 2.2. What I am looking is for a lag fix solution on my 2.2 or rolling back to 2.1 where there are loads of easy lag fix solutions.

head over to the android dev subforum, look for any of the lagfix kernels.
Alternatively use cf-root which will allow you to use 2e recovery and thereby apply your update.zip

Do you know which 2.2 firmware you flashed? Was it jk3 or jk4? This sounds like a recovery version issue and not all solutions support every version of firmware.

Ryan's Z4root to root
+ Ryans OCLF for lag fix works for me .

Any lagfix that can be installed as an app should be ok. You'll still be prevented from applying anything via the update.zip method until you resolve the recovery "issue".

My current 2.2 firmware is JP3. This is what is showing after I updated to 2.2 via Kies.

Yes!!!
Ryan's Root and OCLF worked for me aswell.
Rooting worked fine on the first go but lag fix resulted in a black screen on my galaxy. As I had an external SD card in my phone, I removed it out and ran the lag fix again. It worked this time!!!

Desktop app that seems to work with EVERY firmware version I've tried.
Alternatively, flash one of the custom kernels from the i9000 dev forum. For example, I've flashed SpeedMod which includes root as well as the recovery fix.

Yeah, I met the same problem, once I upgraded to official 2.2.1 JPY. Unfortunately, since Z4root doesn't work anymore, there is no easy way to root it without computer.
Seems like super one click is the best option so far.
Plus, you might be aware as well, adfree can't support i9000 2.2.1. :-(

Thank you, with SuperOneClick it worked .
I'm Root again.

I could not get SuperOneClick working on my Dutch SGS. I regained root on 2.2.1 with CF-Root-XX_XEU_JPY-v1.3-BusyBox-1.17.1.
Just pushed it in using Odin, no problems so far.

[Q] z4Root gone wrong!

Hi you whizzkids,
I tried to get my SGS rooted with z4Root.
Went well the first time. After some time my SGS said "memopry full""
What i did? Back to factory settings (was that a mistake?)
For some reason i am now unrooted and i can't get it back on, z4Root will not finish
My SGS is JPP and FROYO 2.2.1 is installed.
Someone with an idee would be great.
Thanks in advance
Ruud

you cannot use z4Root with 2.2.1
you need to use either CF root or Super Once Click root.
