Yellow triangle after trying to root

J

Hi, I tried to root my phone, but when it reloaded there is just a yellow triangle on the start up screen, and won't start. I have tried a few things, put it back into download mode, and tried to flash a stock rom. But, I am now worried, as I don't think that I actually enabled USB debugging before I started it all. Will this affect me un bricking my phone?
Below is what odin said after trying to fix it.

Welcome to the forums James, glad to have you aboard :)

Hopefully i can try and assist you with the issue you are having today!

If you can tell me the model of your device and what version of android it is running that will certainly help!

USB Debugging will not allow you to root your device...If you made a backup i would suggest to just restore that back onto your device.

Thanks for joining hope this helps :)
 
It's a samsung Galaxy S2 GT-i9100. I had ICS 4.0.3 on it before, but wasn't offcial, I had already rooted it succesfully before. Should I be trying to now flash an original kernel to it, or a stock rom? If so, please could you give me a link for which one to use. I am with T-MOBILE UK. Hope that helps. Can't believe I forgot to enable USB debugging. I hope I can get it working again.

Thank you
 
Hi, have looked on there. Do I need to just download the stock rom and kernel for T Mobile UK for my phone? I did try, by multiupload is saying the files don't exist because they infringed copyright?
 
Just reading something else, saying to update firmware, you need to enable usb debugging, which I stupidly forgot to do. This being so, how can I update firmware on phone, to get it working again?
Thanks
 
When I try to install stock roms, I get this report on odin

Hello and welcome to Android Forums james198320!

If you are trying to root your device then you need to read and carefully follow the instructions in posts #1 and #2 in, "Rooting Galaxy S2 - Dummies Guide".

If you are trying to flash stock Samsung, un-rooted, firmware, just follow the instructions in post #1, here, under the heading, "My firmware is not eligible for ICS yet but I want it now!".
