[Q] Nexus S 4g official ICS problems

---

So I know there are various other threads similar to this out there, but none of them have solved my problem so here it goes. Yesterday, I restored back to my Official 2.3.7 from CM9. I had heard the the official ICS had come out and wanted to do a proper update from stock rom. So I did this and the tried to update, but the update failed half way through. Since then, I haven't been able to connect to usb and I haven't had a cell signal. Does anyone know what the problem is and how to fix it?
Edit: So now I tried, stupidly, to just reformat everything. I'm sure you could see how that was a problem because now I'm stuck in bootloader or clockworkMod Recovery unable to install any operating system whatsoever...

go into clockworkmod

Clean Installing Roms:

1) format /system /data /cache /boot
2) wipe dalvik cache
3) flash rom and gapps
4) Boot up for the first time and it should work
5) Optional: Only do this after you booted up once. Flash the kernel.

Updating Roms and Kernels:

Wipe Dalvik Cache and Cache before updating

That should solve it. make sure you wipe ALL of those.
