4G/LTE Problem with CM 10.2 topic

Hoping to find some help here. I have searched the web and no definitive answer. I was running CM 10.1.3 on my Razr Maxx for a long while. Just flashed to CM 10.2 with Android 4.3. Since flashing, I no longer get a 4g icon for my signal, I get LTE. In addiiton, the LTE signal fades in and out and most times the bars are white which I have found out means I'm not synced with Google servers. I have played with the APN options to no avail. Is anyone familiar with this problem? Is there a fix? Thanks for any help you can provide.

[Q] Updating for Dummies (Xoom 4G/LTE) topic

Hi smart people,

Can anyone point me to a thread written in laymen terms, UPDATING FOR DUMMIES with step by step instructions?

I bought an un-rooted Xoom 4G/LTE in great condition off ebay. It has ICS 4.0 and I was told by the seller that it doesn't receive OTA updates, and that I could manually install them. Thinking, hey I am a techy girl, no problem!

Every 10 minutes it is prompting me to do a 4.1.2 update, but it won't work. I'm stuck and wan't updates, AT LEAST Jelly Bean, but of course KitKat would be amazing (however that may be way beyond my abilities). I have spent the past couple weeks on the Android forums, trying to teach myself where to begin. All this rooting/un-rooting, kernel talk has my head spinning and I am a little scared of permanently destroying my tablet.


In case it matters, here is what I know about my tablet:
mz600
Kernal 2.6.39.4-g42a0480
android-build@vpbs1 #1
Build number IMM76l

I am out of contract, but it is connected to Verizon 4G/Lte network


Thank you for your help,
April
