Easiest way to rooted stock 2.3.6 on SGS2 is to root 2.3.4 and then upgrade

---

I've seen a few questions on the forum asking how to root a 2.3.6 SGS2.

DooMLoRD's Easy Rooting Toolkit was a very easy way to root, without having to flash insecure kernels and all of that, and was great if the goal was just a rooted stock device. It was perfect for me, as all I wanted was AdFree, Titanium and OpenVPN on my device.

Unfortunately, the exploit the Easy Rooting Toolkit used seems to have been fixed in the SGS2 2.3.6 firmware and the toolkit doesn't work any more (see, for example, here).

Before I upgraded from 2.3.4 I prepared myself to mess around with ODIN to get root back after upgrading.

Imagine my delight after upgrading (via OTA), that I still had root without doing anything at all!

So it looks as if upgrading a rooted 2.3.4 stock firmware to 2.3.6 results in a rooted stock 2.3.6 firmware (for I9100XWLA4, at least).

Which means that the easiest way to get to a rooted stock 2.3.6 SGS2 is to root it using DooMLoRD's toolkit before upgrading.

Sorry if this is obvious and, if not, hope someone finds it useful.

not everyone can update or have the option to update OTA!

whats so hard about using ODIN to update then flash CF-ROOT?!

Hi

Nice to hear - I'm on 2.3.5 Nordic and expect an 2.3.6 update before ICS arrives

But also a bit strange that you keept ROOT!
Other attempts using zergRush Exploit on 2.3.6 have failed as far as I know.
Could it have to do with the fact that you updated through OTA and not KIES?

OTAs just replace things that changed - KIES does what is effectively a full Odin flash.
