Yeah, that power & home button shortcut didn't work for me...Otherwise, experiencing the same issues
I have an unlocked S2 that I was attempting to upgrade the firmware to ICS via Kies on a PC. Everything looked good bu at around 85% progress in the installation or downloading process of the update, it froze.
Stuck on the 'Firmware upgrade encountered an issue. Please select recovery mode in kies & try again.'
I can't get it to change from this screen and I can't upgrade or reset the phone. I attempted the reset with the hold, vol. down & power buttons pressed but it brought me to the rooting option screen. I could choose to root or reset but resetting brought be back to the frozen screen I mentioned. I've restarted the phone (removing battery) and kies but nothing works.
Am I only left with trying to root the device or can I somehow manage to get back on the upgrade track (Which I prefer)?
I've gathered from elsewhere that my best option is to flash the firmware...I have a Mac 10.6.8 and I saw somewhere that Heimdall supposedly works well in place of Odin...I downloaded what appeared to be the correct ICS firmware for my country and carrier although when I tried to have the md5 file load into the Heimdall program, I received an error message about it being malformed...Moreover, I am unclear as to how to locate the PIT file that is mentioned in the guide
