[Q] Rooting Froyo JPO

Hi, just got my SGS back from being repaired. been flashed to JPO which is what i was doing when i bricked it. Fixed under warranty so all good there. Now i wanna root it again but confused about it with 2.2 , seemed easier under 2.1
Oh and the good news is I now got 3 button reset which i never had before. Yay for me.

I just installed z4root from the market and it rooted my phone in no time, just had to enable usb debugging when the app asked me to, and it restarted once...
Running froyo.xwjpa (French firmware)
Sent from my GT-I9000 using XDA App

[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!!!
