Samsung Galaxy S2 message "Firmware Upgrade Encountered an issue" and won't boot up

[heathervet]

I was informed that I needed a firmware upgrade when I plugged my phone into my pc, so I spent all this time backing everything up first (thankfully), and then proceeded as directed. Right at the end of the 30+ min upgrade, it said it couldn't proceed (can't recall the exact wording), and told me to remove the battery, then replace it, then try the upgrade again. When I did this, the phone said "Firmware upgrade encountered a issue. Please select recovery mode in Kies and try again". However, the pc cannot seem to connect to the phone now, and I'm about to lose my mind. I am on call this weekend and need this phone back up and running asap. I tried the battery/sim card removal, and I tried holding the volume up and the volume down key while pressing and holding the on/off button, and then releasing the on/off button while holding the volume up/down buttons, but nothing. Please please help!

note: all F-bombs have been removed from this message, but they were in there...

Hi Heather - welcome to the forum. If you're still experiencing problems with your phone, do what Ollie suggested and provide us with your carrier and what country you're located in. That's a starting point for him diagnosing the problem and giving you a solution.

Hello! Are you familiar with Odin?

AT&T has two versions of the S2. Which one do you have?

Firmware Upgrade Encountered An Issue.....with the Yellow Triangle with Caution Sign

No, Odin does not require root. It is a software that is used to flash firmware, modems, and kernels onto your phone.

Odin mode is the proper mode...

I will link you to the proper firmware and instructions.

Here is your firmware. Download it and unzip it one time using 7zip or WinRar to a place you can easily find: Hotfile.com: One click file hosting: I777UCLE5_I777ATTLE5_ATT.zip

Download Odin 1.85 and unzip it once as well: http://forum.xda-developers.com/atta...3&d=1304094576

Then follow these instructions:
Firmware upgrade encountered an issue. Please select recovery in Kies and try again
