[Xoom Q&A, Help & Troubleshooting] ArakniD:
Same issue here.

My misc partition ended up with some N_01.3... CDMA reference inside it.. where it should have been the N_01..83P UMTS..

I believe this was from a US 3g image I loaded... bye bye 3g..

tried the SBFs, the 3.1 telstra w/ baseband updater (which goes through to 100%.. but still no 3g)

fastboot getvar all reports all the correct baseband versions..

still no love..

using the mdm6600 control interface, I can even get the chip into its bootloader mode..

I tried the EOS ICS image for shiz n gigles..

I reset my device by loading on the standard 3.0.1 firmware, then loaded on the universal rooting patch..

went into the recovery mode, the one supplied for the tesltra device... ok this looks weird!

and my getvar all returns

now this is clearly wrong.. baseband-2? I have no 4g upgrade?

no real stranger here... my misc partition now contains "ltedc_u_03.6f.00" inside it.. instead of my previous correct version.

so now it looks like i've overwritten my device even more :)

I have a copy of my brothers xoom which is working just fine.. and that misc partition contains the correct information.. I did copy this in before attempting a standard image again.. before the ICS trial tonight.. still no love!
