just wanted to check a few things before installing jelly bean on galaxy s (still on stock froyo) on my friends phone

1. Is is safe to directly flash cm10.1 straight from froyo?? or is it necessary to flash ics /gb
2. do the instructions on cyanogenmod work for installing (it says no need to root)

1.) Best to do this:
2.3.6 GB (root) -> ICS -> JB

That way you don't lose your IMEI (which causes no signal)

2.) You do need to root because you need a custom recovery in order to flash custom roms.

You need to upgrade to Gingerbread 2.3.6 first and after that CM 9 and finally CM 10 (This is the best way) , As long as you have CWM, you can flash ICS or Jbean from your SD card

so visit My Android Collections and use i9000 Upgrade or Downgrade to GingerBread 2.3.6 ROM JVU + Root with a 512 Pit File (repartition Ticked) Ideal base for upgrading to ICS and J.Bean

This package already has root and CWM

But first save all your important files ( Backup sms,contacts etc) including your efs folder. as you may never know what can happen when Flashing.

any guides you may need look in My Guides and manuals

if you already know how to use Odin3 and flash a ROM, all guides will lead you to the same destination. I think the downloaded ROM already has a guide, just remember when you want to flash, charge your phone, kill kies and never disconnect flashing process.

"CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.tar"
