Stock AT&T GB, boot loop

---

Last night my wife's S2 battery died. When she plugged it in it comes up with the Samsung Galaxy SII splash screen, then black and then the splash screen again. We let it charge overnight and the charge looks fine. When I tried again this morning to turn the phone on I get the same results.

So I thought I'd be able to get into download mode and flash the stock ROM with Odin. I'm able to get into download mode, but now the problem is when I hook it to my PC via USB I'm getting an Unknown Device error. I've tried to reinstall the driver itself, un-installed/re-installed Kies and the drivers...still no luck. I've also went into device manager and uninstalled the unknown device, rebooted and as soon as I reconnect the phone I get the same message. I've even used a toothbrush to clean the micro USB port, just in case.

I'm sure if I can get this to connect properly via USB I should be able to get the phone back up and running.

Any ideas?

Try to reboot into Recovery and then Wipe data/factory reset and Reboot.
Or wipe cache first, then try to reboot. And if a no go, then wipe data, reboot.

Her phone is stock/unrooted.

Probably sent from the bathroom.

No prob. Hold volume + & - together with Power button until it reboots and u see the Samsung Galaxy S II screen, then release all buttons.
Navigate in the recovery up and down with volume buttons and select what u want with the power key.

Oh, I didn't even try that. I rooted my skyrocket and putCWM recovery on it. I didn't know there was a recovery by default that I could boot into.

Thanks, I'll give it a go.

So I tried the cache first/rebooted, then did the factory reset/reboot. Now I'm back to the Samsung loop again. Plus now if I try to go to recovery I get 'Deleting Cryption Meta Data', then it goes back to the loop.

Man I hope that phone wasn't on stock ICS...

When u said stock, i was thinkin GB.

You're right, it's GB...it's in the title.

Whew !! Good !! Because u do not want to do a wipe data from the Stock ICS Kernel.

Anyway, it looks like u r gonna need to get into Download Mode and Odin or Heimdall back to a Stock Firmware. Not sure why ur pc isn't recognizing ur phone though...Did u reboot ur pc after the uninstall of the drivers, then try and reinstall ? (<---see in ur OP that u did)... And connnect to a usb port in the back of the pc, not a hub. Try a different micro usb/usb cable.

And see this post about the "Deleting Cryption Meta Data'" .... http://forum.xda-developers.com/show...53&postcount=7

Yeah, I've tried it all. Even a different PC.

The phone is still under warranty, and I think that's going to be the route I'm going to have to take. Just hoped to avoid it because it'll take 6 days or something to get a replacement from AT&T.
