how to connect to 4G after root?

Hi,
I followed this thread and rooted my Xoom successfully
http://forum.xda-developers.com/showthread.php?t=1242241
Before I rooted I was on the 4G network, now I can't get on the 4g network. I cannot even get on the 3g network. I have Data enabled under mobile network settings and I activated my device.
Any ideas on how to connect again? Wifi works.
Is it possible I wiped the 4g upgrade off the xoom by rooting? thanks

Pull your sim with power on. It will give a msg, then put it back in and reboot. Make sure wifi is off too.

Hi thanks for the reply
I did this and didn't get any message. I pulled it and now rebooted it. Still no luck
edit: to make it more clear it says no internet connection but the signal fluctuates and it says i have 3.2.1 is that the problem? I think 4g+ is 3.2.2 but even my 3g isnt working

I fixed the problem
I tried using the 3G method to root it after it was unrooted because of the 4g method. That didn't work so I flashed the oem boot.img file. That was the 3.2.1 file when I was supposed to use the 3.2.2 one that Motorola just released about a week ago
I went back and used the oem boot.img file this time 3.2.2 and it worked.

[Q] lost wifi overnight while sleeping running cm11

Ok guys. Flashed cm11 3 days ago and everything has been working great. Woke up this morning and i get no wifi signal. Wifi is on but it picks up no wifi signals. I am in a spot where there are 5 to 6 wifi always available and none are showing. Any guesss as to why I no longer receive wifi signals into my phone? I was hoping just maybe switching from dalvik to art would fix the solution but it did not. I am hoping this is just a simple fix. I guess i could just reflash cm11.

reflashing cm11 did not fix issue. when refreshing wifi i get : WPS has failed error.......

Try updating your build. If that doesn't work then I would do a clean flash of a "Stable build".

lost root that was the issue
My issue was not the wifi it was i lost root updating to 11.0. I tried using super su to get my root back and when i did it caused me to lose wifi. It did not get my root back either. I can reflash with factory reset and get everythign working like it should, but root is gone. Flashing the newest super user does not fix the issue. I think my only option to get root is to go back to factory and re-root and then start from scratch.

No wi-fi on sspence 11-23
I also lost Wi-Fi on sspencer10's 11-23 build. I am using ART. Restoring 11-21 build brought it back, but I am waiting for new build to try again.

WPS Failed
I've never had WiFi on CM 11 and did a clean wipe to fix it on an earlier nightly. Even the Snapshot build did not fix it for me.
Is there any fix out there?

My Oneplus is very peculiarly dropping network when try to call

I am very perplexed by this very peculiar problem which apparently no one has
I bought my OPO here in UK, it arrived swiftly and i could not be happier. But wait, curiosity killed cat( in this case me) I was able to use my OPO regularly but i did a mistake and saw coloros posted on oneplus development and gone ahead and installed it via fastboot.
Next day reverted back to CM11S via fastboot.
Now the whole time my EE sim was in the phone. One day morning i can't able to make calls, as soon as I try to call nice 4g signal goes completely down and phone give message that no mobile network.
I tried vodafone and O2 sim which sim to work nicely but now no network all.
I got new EE sim, and voila again comes back network after factory reset. I try to make a call and again the same thing; network goes out completey.
Please help.
I have already put the request with paypal requesting refund, now I don't know what will happen
But in meanwhile if there is something I can do please let me know, also some senior members can explain why is this happening

Try installing the latest radio/modem. Download the latest OTA here, then extract the file called NON-HLOS.bin.
Reboot into fastboot, do fastboot flash modem path/to/NON-HLOS.bin, reboot, and see if that helps.
Your network problems are probably because you still have the ColorOS radio image.

Try setting it to WCDMA Preferred, or LTE/GSM (Auto PRL) which is what I use... it doesn't completely solve the problem for me but it helps in most areas.

I agree with him. It seems like your phone is getting 4G signal but since the OPO does not have Voice over LTE (VoLTE), your phone is forced to go back into 3G mode in order to make the phone call. Set it to LTE/GSM (Auto PRL) as what hashim said and it should fix your problem. Your phone is probably on 4G only mode.

The same thing happened to me on Fido in Canada. I side loaded the 30O update and went back to 25R. When I reverted I was not able to accept any calls or texts. My phone would get the com.android.phone force stop error. I tried deleting the data from the phone, contacts, and Sim Toolkit apps but ultimately had to do a factory reset from recovery to fix the issue. Lost all my progress on Final Fantasy VI too..

Guys I love xda community my problem is solved

Many thanks man
I got it sorted with your method. I tried this also before but on windows 8.1 machine but no luck. This time I tried with another cable and on Mac so this time it worked. I was on verge of returning the phone.

[help] no signal after update to 5.0.1

Hi all!
i have XT1033 Model of moto G.
I converted it to GPE for months, OTA to 4.4.4 and everything is fine.
Yesterday, i got the notification that OTA 5.0.1 is avaible. Of course, i pressed "install and reboot"
I got stuck at logo Google, then i solved it by flashing GPT.bin. Phone boots fine now
But the problem is my moto G lost signal. it still recognizes Sim card because when i re-insert Sim card, it asks me to reboot the phone.
I checked baseband, it is fine ( not unknown).
So how could i do to take my signal back
Please help me! Thks all!

anyone ??

Why removing? This can be helpful for other users.

I had te same, tried all reflashing and even back to 4.4.4. But the solution was very simple for me, i just needed to select the network again. (network operators)

5.1 WiFi dropping?

Never had this problem before on the previous versions. But I have now noticed that occasionally it would drop and disconnect for no apparent reason!

I'm assuming your stock unrooted? How did you update? ota? Fastboot? Does it do it for all WiFi or just one? You can try forgetting the network and reconnecting and make sure your WiFi connection is good. Is it doing it on any other devices? You can flash factory images and have a fresh install.

Think it's a Lollipop bug.
