ICS Update screws up Recovery

[ilaifire]

This morning as I was heading out the door I looked at my phone and it told me there was a new update available. So when I got to work I made a nandroid backup, backed up all my apps, and installed ICS. It worked perfectly and exactly as I expected, also as I had guessed I no longer had root, well not a big problem I can just restore back to gingerbread I thought. I go into the bootloader and try entering recovery and all I get is a little android logo with an exclamation point. When I try reflashing a recovery image, adb and fastboot can't detect my phone while it is in the bootloader.
Both ADB and Fastboot can detect my phone while it is running normally, just not while it is in the bootloader. I've tried googleing the problem and tried several different solutions, but I can't seem to find anything that works.

Thanks,

First I would install PDANet on your computer. This usually irons out connection issues (drivers) between your computer and device.


Then yes, you will have to reinstall the CWM recovery. When you accepted the update it not only removed root but also replaced the custom recovery with stock recovery.

i tried and achieved root after the ota/official ics upgrade. when i reboot cwm doesn't stick! i had the same issue! i had to Restore To Stock/Unroot back to gb to get cwm to stick... the official ics is boring and only lasted six hours before i re-rooted!

I had tried installing PDANet, though I'm not sure if it worked. What I ended up doing to flash the recovery was to use the serial number you see at the top of the screen in the bootloader. For some reason neither ADB nor Fastboot had the device listed.
If anyone runs into the same problem:
fastboot -s xxxxxxxxxxx flash recovery recovery.img
