4G band not Working after rom change - Moto Maxx Q&A, Help & Troubleshooting

Hi all, I installed the nexus experience in my moto maxx XT1225 BR but the 4G signal went dead, 3G and 2G is working perfect and also everything else.
I did a full backup (just in case from the 5.02p) before and the 4G is working fine if I go back but the battery drain is just epic, with the original rom it last 8 hours and with the nexus experience 1,5 day.
Is there any way to extract the radio from a TPRW backup? Because I tried all the radios listed in here but can't get to work the 4G on custom rom
Thank you in advance to all.

You tried the radios listed in the CM12.1 thread, post #1?

same problem here, after installing CM 12.1 nightly and the new baseband, my 4G LTE stopped working. before when i was on cyanogen + 5.0.2 baseband, LTE was working fine except for GPS .

[Q] Not Getting Network on a Particular SIM

This is by far the strangest problem I'm facing with my Nexus S
I've two SIM cards from two different networks. one is GSM 900 and anothe is GSM 1800
Both the SIMs are perfectly ok and functioning very well in my Nokia X2.
But one of the SIMs (GSM 900) is not getting any network in my Nexus S.
Interestingly I've been using this very SIM (GSM 900) in my nexus for last one month.
Just to give a background, I'm facing this problem when I flashed the latest 2.3.7 stock ROM.
I tried flashing other ROMs aswell...Currenyly I'm on MIUI...but no Luck ! And Yes, the Other SIM is working absolutely fine with my Nexus and fine with both the ROMS !
Please Help !
If I'm not mistaken I believe 2.3.7 is an update for nexus s 4g models only and not GSM. That is a very good chance as to why your network doesn't work.

But it was Getting network. And My other SIM is getting network in that OS.
BTW, I've flashed a different ROM (MIUI)....No luck with the new ROM...
frequency base band problems perhaps ?
Yes, its Reading 1800 SIMs but not 900 SIMS.
all what you said so far indicates that the problem was caused by the new binary.
it seems the hardware is working fine.
what is the software version of your phone?
download an official version of Nexus S and you'll be fine.
tell me what you see in the "about phone"
Android Version: 2.3.5
Baseband Version: I9020XXKD1
Currently I'm in MIUI. Searching for the official version of 2.3.4

2.3.7 is for the cdma nexus s 4g not a GSM model. Try reflashing the correct radios for your phone.

I've tried Flashing Radios. But Yet its the same scenario !
Getting network with a GSM 1800 sim. Not with GSM 900 SIM (Unfortunately this is my official number)
Can anyone suggest the exact stock ROM for my sns. I tried to search here in XDA, but not finding the exact one.
the sticker in back says my SNS model is GT-I9020
Some files may stuck in /system partition when you flash something, and good idea is to format /system from CWM recovery (you can find it under mounts and storage section) and flash rooted flash rom from here - http://forum.xda-developers.com/showthread.php?t=1063664.
It's always a bad thing to flash something that is not meant for your device.
Formating /system before you flash stock rom. Hope that could fix your problem too, but I'm not sure . Just a suggestion ...

I've flashed this from Google
http://android.clients.google.com/p...206299fe6.signed-soju-ota-121341.da820629.zip
Now my about phone looks like this :
Androd Version : 2.3.6
Baseband: I9020AUCKF1
Build No. GRk39C
Yet, its not getting network.
Should I take it that I've lost my Nexus.
Thanks for you reply Tenhi.
I tried formating Everything ! and also Flashed the Stcok ROM (NSGSM-GRJ22-deodexed-KD1-rooted)
But no Luck.
Interestingly, today I found that the set is getting network in Some places, mostly where the network strength is very strong. And functioning very well with GSM 1900 carriers. But facing the problem with GSM 900 carriers only.
Isn't there anyway to get back to Factory Settings or something like this...?
Don't know what else to say. Apparently the NS4G 2.3.7 ROM changed something permanently, and you can't reverse it with flashing another ROM/Radio/Kernel. Unfortunately I don't have any more suggestions . Hope you will find a way to fix it ...
Yet to get a way to fix it.
Strange problem I'm in.
Now looking for a nandroid backup. (Downloading this http://forum.xda-developers.com/showthread.php?t=1059914)

At this point I'm loosing hope...

I had one Stock ROM backup (2.3.3). I flashed it today. Which updated the Radio to KB3 also.
But the problem persisted. Then I took the offcial update to 2.3.4 using the push update.
Yet the problem is not fixed. Not getting any clue on what happened !
I've tried two different operators who run GSM 900 and its not getting network with them.
But There is no problem with GSM 1800 operators. Its running smoothly with GSM 1800 SIM.
Alhamdulillah, the problem has been solved.
A OTA update to 2.3.6 has solved the problem for me.
First I flashed 2.3.3, just after flashing it prompted for a update to 2.3.4 and a day after it prompted for a update to 2.3.6.
Which eventually solved the problem
Thanks for your help guys.

[Q] Motorola Xoom CyanogenMod 11

Hello,
i am trying to get Cyanogenmod 11.1 working on my Motorola Xoom US 4G Lte. I was able to get this installed and working great with the exception of my mobile data is not working. can you someone point me in the right direction to get this working or maybe recomend a rom that has 4G Lte working and is stable?
thank you
I think the OmniRom equivalent MAY have data working, but I'm not 100% on that (I use the wifi only version). Best to check out the thread.

[Q] Moto G update 4.4.3 problem WiFi

Good day dear users, first of all sorry for the bad English, I'm Venezuelan translating with Google translator.
My problem is that my Moto actualize G 16GB GSM Global purchased on Amazon and sent to Venezuela. Before the 4.4.2 upgrade the WiFi worked perfectly fine, but with this update 4.4.3 WiFi constantly drops every 5 seconds so I this next to the router, and routers and tested two different brands and the problem continues, I a hard reset and the problem continues, are able to stabilize a bit after about 5 times placed in airplane mode, it bothers me a bit since this problem and wanted to know if anyone happens if you open a solution that does not go back to 4.4.2 since the performance of the battery if this better in 4.4.3.
Also I know about 10 other users in Venezuela Moto G happens the same problem after upgrading.
Greetings and thanks, it's my first post in this great forum so sorry if I have any errors in the post or is not the correct area.
Go to adv wireless config and untick avoid bad connection, i was having the same problem with WiFi, after that no WiFi drops for me

Hey man. Well if that problem happens to us in Venezuela with Moto G of North American is the one I have and yet still can not find solution, and it really is quite annoying to have to return to the previous ROM, I'm in search of some solution but nothing that I find .
Well im from Venezuela too, bought my phone on Amazon and is working fine with 4.4.3, also is unlocked, rooted and with custom recovery, one thing i did was flash the 4.4.2 firmware first (had installed faux kernel and philz recovery) then update to 4.4.3, had the WiFi drop problem 2 times, after disabling the avoid bad connection thing, no more problem and my Phone is working fine with wifi

Well then, I got to go back to 4.4.2 and all problems are resolved, a shame really, I hope this motorola resolved soon.

May provide some clarity!
Someone have made a wipe dalvik?
Flash any WiFi modules?
Happening to me aswell but can't say if it is due to different region/modules or due to the 4.4.3 update. I flashed GPE on my brazilian firmware and stayed on it for like 40 minutes, everything was fine. Wifi started dropping after I went to PA 4.4 RC1 and can't manage to reconnect without going on the modem and restart it from there, a reboot on the phone doesn't help.
Any ideas?

[GPS ISSUE] HTC One M8 VZW - & CM12 based ROMs

First of all, this issue isn't just gonna get fixed by flashing a Sense-based ROM, then going back to CM12. This goes deeper than that...it seems to be working fine for guys running the same ROM with TMO and other carriers.
What does anyone know about GPS not being able to communicate with GPS satellites when running most CM12 ROMs with Verizon's 4.4.4 firmware on your M8? Could this be kernel related? Is it that Verizon 4.4.4 firmware (CDMA) is conflicting with something? Any input would be appreciated. Thanks!
same issue on Sprint m8

That does fix the issue for a lot of people and is recommended across devices when trying to get a GPS lock on an aosp Rom (example: vzw note 2) also, some people have to do it a couple times before it works. If it still isn't working for you you can try a clean flash to stock sense get the lock etc, and then copy gps.conf from /system/etc, restore your bAckup of cm12 and paste it in the same place (back up the original first), set perms to 644, reboot and hope for the best

Just so I said it, I've got the same issue on the sprint version.
Lost GPS
I did as you suggested and tried Skyfire. The gps worked But no service or mobile data (waa waa). I made a copy of the ect/gps file and replaced it once I flashed back CM 12. Un fortunatly that didn't do the trick. Thanks for the suggestion though.
