[HELP]Lost 3g after flashing over factory image after LTE upgrade

[mmayhew]

Many others are having this same issue with no resolution. See threads at the bottom of this post.

I received my Xoom back after the LTE upgrade and confirmed it was 3.2.2. Like a freaking idiot, instead of Rooting the factory installed 3.2.2 image, I just flashed Solarnz's 3.2.2 ROM assuming it was basically the same thing. At that moment, I lost 3g connectivity and have not been able to gain it back.

I noticed that under "Wireless & networks -> Mobile networks -> System Select" I have Automatic or Home. Before wiping the factory image, I had "LTE/CDMA" options which the instructions specifcally mentioned.

I'm very confused because AxeMachine confirmed that he DID have the LTE/CDMA option when flashing one of the same images I tried. See here

*Yes, 3g was working with the factory image
*No, I did not do a nandroid (I know, I know...)

Images I've flashed:
[ROM/UPDATE] Android Honeycomb 3.2.2 - Stock & Rooted.
The nandroid short/y posted here
The image AxeMachine posted here
3.2.2 "PIlot" image posted by AxeMachine
I've also re-locked, went back to 3.0.1 and upgraded via OTAs to 3.2 but don't get prompted for any further updates.

Yes, I always fastboot -w (wipe userdata and cache) unless the image comes with a userdata partition.

Like many others, I've spent an hour on the phone with VZW support and confirmed it's not an issue with my area or account.

This is the behavior:
*The radio works and detects the Verizon Wireless network.
*Activation succeeds
*After disabling/enabling Mobile Data, Mobile Status says 'Connecting' but then changes to 'Disconnected' after a few seconds.
*In this logcat you can see it disconnecting, reason=null xoom_3g_issues - Pastebin.com

Below are posts from people having the same problem as me. I have PM'd most of them and confirmed no one has found a solution:

Re: [HELP]Lost 3g after flashing over factory image after LTE upg

I did almost the same thing you did, just this morning in fact, and I'm currently sitting at the 3.2 (with no updates available) and no options for LTE/CDMA under system select.

I should of just been content with what I had, no i don't have either!

Thanks in advanced to anyone who can figure it out.

I am in worse shape... but I have basically the same problem

I am stuck at 3.0 build HRI39 and OTA updates are failing... (wifi working, 4G radio unrecognized)

AC is a failboat for help anymore...
