Cant access recovery/Opreating System - Galaxy S II Q&A, Help & Troubleshooting

my ROM is faulty and im trying to switch to another rom
but my home button is not working so i cant access the recovery
and when im trying to plug the phone to the computer im getting UNKOWN DEVICE ERROR
and because the unkown device i cant use the KEIS software to install another ROM
and ideas what can i do to solve the problem ?
thanks in advnace!

Hopper8's 'Odin troubleshooting' thread stickied in General, pay particular attention to the suggestions around connectivity (I.E phone/PC not recognising each other). these still apply to you even though you're attempting to use Kies (why you'd do this & not simply flash a stock rom manually with Odin I don't know, but, anyway...).

Help unbricking my 4.0/YP-G1

Yeah so I had some terrible luck today. I was flashing a stock rom with odin, and then my USB cable attached to my player got caught on something, thus causing my phone to fly in the air and the battery to fall out. Basically, bottom line is that my battery was removed while flashing something in Odin.
Now every time I turn my player on I get a picture of a cell phone on the left, attached to a computer on the right with a giant caution sign in between them. I can't seem to boot into recovery or download mode. Odin doesn't seem to recognize my player either. I'm worried my player is bricked for good, but if anyone could help me prove otherwise, that would be amazing. Thank you.
Edit: The symbol looks like this:

Thanks for the response. It turns out Odin wasn't recognizing my device because my USB cable wasn't plugged in all the way (genius, I know).
I flashed the stock tar though, and now I'm getting a bootloop. And yes, I made sure not to re-partition.
This is the stock package I used: http://forum.xda-developers.com/showpost.php?p=41424020&postcount=384
Never mind. I got it! Thanks for the help, simple as it was.

[Q] S2 stuck on warning sign, no download mode[i9100G]

Hello, I got an S2 phone from a friend with a problem, it boot-looped showing only the Model and logo(Where it says i9100G), I tried flashing some ICS stock firmware, it stuck on the NAND write line for a while then failed.
I tried entering Recovery mode before, but it didn't work, maybe I didn't try hard enough but I heard on other threads that deal with soft breaking that this might mean a problem with NAND r/w (Don't know much about this problem).
Anyway, after the NAND problem, the phone doesn't work as it used to, it now only shows one screen with a phone and PC icons(See attachment or link), with a warning sigh in the middle, I thought maybe Kies can handle it, but when I connect the phone while running kies it just keep on trying to connect to the phone and I don't think it will stop for a long while, so I can't use the help of the Kies emergency recovery for now.

Try to repeat the procedure, sometimes it might happen that odin get stuk, restart odin and get back to the download screen on your phone, you should be able to try again. If it keeps happening it might be that is the wrong version for your phone, I would suggest searching the original firmware on SamMobile and use odin to install that back.
Hopefully this helps, I'm no expert, just run into similar problems recently
