[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] 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!!!

[Q] Un root for samsung galaxy s running on android 2.2

Hi, I have a samsung galaxy s i9000 running on android 2.2 and I'm trying to find a solution to unroot it. I've rooted my device however there does not seem to be any solution to unroot a i9000 running on android 2.2
It seems that only the i9000 running on android 2.1 eclair is able to unroot and not 2.2. I would really appreciate it if anyone of you here could give me a solution or programme to unroot the i9000 on 2.2
PS: the one click fix programme of something like that only works for 2.1 eclair.
thanks alot.

What root ???
What ever you rooted with normally tells you how to unroot .
It seems that only the i9000 running on android 2.1 eclair is able to unroot and not 2.2
Unroot is a specific of the program you rooted with
I rooted 2.2 with Z4Root and unroot it with Z4Root .
jje

the reason I don't use z4root is becaise there is a trojan virus embedded in the file. Thays why I am trying to find an alternative to z4root on this forum. I want to find a way to root and unroot my fone on 2.2 without embedding a trojan into my phone and computer.

That's a false positive from the antivirus... it does that with that type of software and keygens
Sent from my GT-I9000 using XDA App

[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

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