It should only be about 5MB, it's just the stock kernel you need (i.e. the second BVKJ4 link).

Oh, it's finished downloading and I see when extracted it's actually just that one file.

Here we go, fingers crossed...

I saw your post just in time. I have downloaded the stock one, at 5.1mb.

I could have made another horrible mistake if I'd gone ahead with things. I will now attempt to flash the 8mb Kernel_I9100BVKJ4.tar.md5 file from that archive I've just downloaded (the 5mb one).

Have I missed anything?

I don't think so. Just make sure you follow the instructions from Intratech's thread linked earlier, specifically Flashing Firmware with Odin.

Well, flashing that stock kernel has done wonders. Thank you so very, very much!

I will try to find the thread where I was reading about this zergrush exploit working on this phone. I can only assume I'd read it and read this one after and put the two together by mistake. I don't particularly understand the whole thing which is why I liked the idea of this exploit as it keeps things stock.

I will see if I can find that thread and read it carefully.

I think I'll call it a night now, and get to bed. Thanks again.

You're probably still rooted, since zergRush did its thing earlier, and flashing a kernel shouldn't have changed that. The only thing you did wrong was using a CF-Root kernel (zImage) for a different device. If you'd have used one for the right device, it should have worked fine.

I'm not sure how I'd check for root. I don't have that superuser program available as an app.

You could try running an app which requires root and see if it works, but if you don't see the Superuser app, it seems unlikely it will. Anyway, if you're still feeling up to it, the simplest way to root (in my opinion) is using the same exploit you tried earlier, but from a different thread (and it doesn't come with the risks of using the wrong kernel ;))

Takes about 3 minutes.

I think I've found thread I was reading earlier today...

What part did the ZergRush affect, if not the kernel? If I use this version, with the correct zImage file if I can find it, then I should be ok second time around.

lol.. the joy of cross posting!

I was going to go to bed but now you've made me want to finish what I started.

Please work....
