Default Cannot perma-flash custom recovery

Hey guys!

So I was helping my friend flash a ROM to his S2(G) but the problem is, after flashing the zip file for the recovery in the stock recovery as is recommended in the guides here, should I reboot, it once again reverts back to the stock recovery, and not the custom one.

Can someone please help?

Thanks again.

And please ask me for any more details if necessary.

That's because the partition layout on the I9100 is different to other phones; recovery is 'baked' into the kernel & not in a separate partition. So that's why when you flash a recovery independently, the recovery will revert to stock recovery (or whatever custom recovery the custom kernel you're currently running has) when you reboot.

You need to flash a custom kernel which will give you a rooted phone + permanent CWM; PhilZ seems to be easy (search for the thread).

If you want a specific CWM version, you'll need to flash a kernel that has it.
If it's important enough to cause you grief if it's lost, back it up. No excuses
Trolling for thanks is lame
Does Samsung's auto-brightness implementation crap drive you to self-harm ? A solution !

If you don't know how to recover if things go wrong, what are you doing flashing custom roms ?
