Hi Neal

yes you can update the same!
Hello,
I have noticed something after following your procedure. I have updated my FW and Rooted to XXKG6 (and checked the version on my device and it is OK). However, after I have applied the Custom ROM, the version has become XXKG3. Is this Normal? Also, I didn’t see the “Exynos Extreme” Logo during start-up.
Thanks to give me a feedback.
yes its normal! as it has changed the start up logo!
Thanks for the reply.
I believe you have mis-understood me. Actually, I was expecting a change from the start-up Logo but I did not notice any change. Even the battery gauge on GSII has not changed. Only the marketplace got changed on my device.
Supposively, the start-up should show “Samsung Galaxy SII Exynos Extreme” right? For me it’s not. The same standard logo is showing during start-up.
Thanks for your feedback once again.
no, the start up logo will be the same across! its normal!
