Mistakenly posted this over in the I9100 forum first.

I tried to root an S2 with ODIN and siyah. Afterwards it worked but I noticed that the splash screen showed I9100 (I used the I777 file). Anyway, I later realized that the guy i bought it from had left stuff on it (he reset without wiping). I decided to wipe it and now it won't go past the splash screen and won't go into download mode that I can tell.

I was told in the other forum that I will most likely require a jig to get it to work. Considering I can't even root the thing right, I will probably buy one instead of making one. Does it matter what model of S2 it is on the jig? I see some that say I9100 but not I777. I just want to make sure if i order one I get the right thing.

What did you try to get it to download mode?
To get into Download Mode, I held down the down volume, the home button and the power button. The splash screen comes up but just goes blank after that. I'm afraid I may be out of luck.

Thanks for any suggestions you can give - i feel sick about this whole situation!

You should read the stickies... You're doing it wrong.

Volume up and down plus power. Leave USB disconnected.

Everything is explained in the stickies.... Read them

The sticky I am looking at doesn't coincide with what you are saying, which may be why I am confused. The guide says:

Boot into download mode by this method:

With the phone powered off, plug in the usb cable while holding the vol up + vol down buttons (but not the power button).
When the warning screen appears, press Volume up to continue into download mode.
Which is not giving me a dang thing. Doing your method or any other method only gives me the splash screen then black again.

Sorry. Volume up down and power is for recovery. Volume up down and plug in usb is download. The only way this would have changed on your device is if you flashed primary or secondary bootloader from the i9100

But based on what you said before is that you were following the i9100 method to get into the different recovery and download mode, since the i777 doesn't have a physical home button like the i9100

Well, I followed a video from galaxys2rootdotcom that said it was for I777 and the file I used said I777 but after doing it, the splash screen said I9100. If I hold down the powerbutton and or other buttons while it is not plugged in, I get the splash screen with the exclamation then it goes off. If I try it while it is plugged in, I get a grey battery icon. Sounds like best bet is a jig?

Check out my signature and download the adb portable from one of my previous posts.

It has a reboot download mode batch file that should be able to help you out.

Sounds like your battery is extremely drained. Try leaving it in the phone overnight and then use the wall charger in the morning.

Red - that was my initial thought but it was fine before I did the wipe and I did try charging it some. Also, when I did the wipe, it was plugged in, which makes it odd that it would die. I'll certainly give it a try.

One thing I noticed at home that I had not seen here (it was too bright to notice) was that it does indeed seem to be stuck in a loop. The screen flashes a little brighter every few seconds before going dim again. At this point, it doesn't seem that I have much option but to wait to try to use the jig to get it in download more *fingers crossed*, and then swear to never get advice from rooting from anywhere but here.
