Good day
I am currently in Venezuela and I just received a Moto X pure literally just get it out of the box. When I plug the SIM on the device recognized it I could receive SMS and Calls but no data, no 3G no H+, no 4g. I double checked the APN and nothing. So I look some Info and found this app from the store called "Network" which i think its just a shortcut to the *#*#numbers#*#* anyway below there was an option "lte/gsm/cdma auto (prl)" i change this to other options to try to force LTE but nothing worked. So going desperated press the three dots menu on top and click "select radio band" and by mistake selected USA Band. Inmediatly lost signal and now the decvice doesnt recognize the sim card anymore. I tried to go back to this menu (select radio band) but the only options i see are "USA Band Cellular and PCS" none of this working for me. I ll really appreciate any help you could bring me cause i dont have a phone to replace this one. I also ask the moderator to move this post if this is not the right place for it, I ve been seaching for help but there is just too much information concerning radios, modem, and bands that i can really understand.
My carrier here is Digitel working with this bands
LTE 1800
3G 900
Hopefully you unlocked the bootloader and made a backup before messing with such things. If not, factory reset is probably your best bet.
thanks for the reply
I just did a factory reset and still the same... could flashing a stock rom help with this?
Likely reflashing the firmware will put it back to where you originally had it. If it asks you for a password for anything, it should be all 0's (00000).

First off I've tried searching for a similar topic and couldn't find anything.
So here's my issue. I updated my SGS which I bought from a local O2 store here. Checked that is was indeed unlocked and went ahead to follow the instructions that can be seen here in the forums.
After installation, the language was set to an Eastern European locale, which conveniently was easy to change back to English.
I could not connect to any network, so did all the app installations via WiFi. It wasn't until early this morning when going to work that I noticed that I didn't have any DATA going through.
Checking on the settings, I now have the option to connect to CDMA networks, instead of the option to disable 3G (Only connect to 2G networks).
What do I do to get that option back?
Thanks in advance for your assistance.
You need to manually install your phone network details or AP (Access Point) details.
Firstly check you have any details entered.
Settings > Wireles and network > Mobile networks > Access Point Names
If you don't have any details in here then you need to find the information and put them manually in.
Other then this you can check your Network Mode the next entry below Access Point Names and select the mode you wish.
Mine is GSM/WCDMA auto.
Wish you luck with it.
That's the thing, there are APN's on there and all. It's just that the setting for 3G had now changed to CDMA. Is there a way to just flash the specific CSC and not affect the PDA & PHONE?

PDA must always be flashed. THe other two you can add if required.
WCDMA is the same thing just make the selection you want. No need to flash a different CSC. I'm using JM1 at present and it's WCDMA as it's from Europe but it doesn't effect the phones capability. It's just a name.
Thanks for the reply. So what you're saying is, even if it is saying WCDMA, it WILL connect to HSDPA? Flashing my phone now back to JM5. All other FW's I've tried just show WCDMA instead of 3G.
Eventually settled for JFF and 2G option is back. Now I have the problem of the APN's working. Off to weed through these forums again.
Different question, same problem unresolved. So my original problem is that I seem to have lost all data connectivity (apart from WiFi) after the very first FLASH. OH well. Thanks for your assistance Ancient_One.
WCDMA is not CDMA. It might be confusing a bit, but it's actually two different things. WCDMA is basically just another name for 3G.
(Well, it's a bit more complicated than that, but for the sake of simplicity, let's just leave it at that.)
Yes, WCDMA is 3G. It's not CDMA as used by Verizon and Sprint in the US (they just share some of the radio-level technology).
Thanks for clarifying the bits regarding WCDMA. My how things have changed. Anyway, I'm going back to JM5 and am hoping to get internet up and running. It is so annoying to not have everything working as they should, even after the APN's been added and all.
Much appreciated guys.
So I was playing around with my unlocked note nd I found a selection of bands nd I can select them but not sure yet if it does unable 1700 nd 2100 bands to work on wind mobile or tmobile any ideas ive the pictures
What code did you enter to find those options?
Note 1 had the same menu options.
It doesn't mean anything without actual support in the phone.
I assume, like the Note 1, if you turn those on your phone is going to reject your sim card.

Hi just peeked into this and was able to select 1700 band, go to comi bands and select 1700 wcdma and any other missing band and it will be selected. If it makes any difference i dont know since im in a good refarm area for tmobile.

By the sound of it our hardware just don't have the bands but yet we can select them kinda strange but if you could try using tmobile sim let use know what happens
I was able to do this also, with the leaked XXDLJ2 FW (4.1.2) - I tried with earlier FW before and couldn';t get into the menu - could be total noob error though...
Remove SIM card first.
Then power up Phone, dial #*197328640*
Select: DEBUG/PHONE CONTROL/NETWORK CONTROL/SELECT WCDMA BANDS
from there, it seems you can select ALL, or add the bands you want. (I'm on TMO USA so I selected 1700/1900/2100)
Now, what I don't know is...once you re-insert the SIM ( and you have to power cycle to do that) does the TMO SIM override the changes I just made? I have very weak 4G near my house so I cannot check if 4G is working or not.
CORRECTION: Forget what I said about removing SIM card !!! I was able to access the menu with the SIM inserted, and it looks like my settings are holding ( there's an asterisk next to the WCDMA bands I chose). This is promising!
I did this on a stock rom and after rebooting settings stay the same. Cant tell if itll make any difference since im at work and dont get good coverage. Will report as soon as i can and im on tmobile california
Sadly, it appears that any other setting than Automatic will disable WCDMA altogether - I sat in my car for 20 minutes right under a cell tower tryin to make it work, but was stuck on Edge...as soon as I selected AUTO, my phone jumped to H+ ...and it was on the 1900 Band since the 1700 band is automatically unchecked when switching to Auto. Oh well...gotta wait for the damn TMo refarm then.
The TMUS reframe is killin' me. Neither my house or work are in a reframed area. However, there are several points on my commute that are reframed, and I did have a chance to eat dinner in one. Holy moly is HSPA+ fast! EDGE is virtually useless with these devices.

you can select mulit bands that way you dont have to use auto as it does turn em off ,i used the last selection it lets you select what you want
Sorry to check in late but with these changes I notice that my signal sticks to 2g and barely wants to switch to H or H+. Maybe when Im off work Im gonna try to select all wcdma band and switch to wcdma only in network mode. when selecting network mode i notice it changes all the settings in the service menu.

that's what I've been doing - COMBI BANDS, and add GSM 850/900/1800/1900 and WCDMA 1700/1900/2100.
But it didn't work for me, phone remains stuck on EDGE -
I dont think this does much only put me in Edge mode or no data at all. Its weird that theres an option for it. So ya no luck here...
Dear All,
I've bought a RAZR M in the states a few weeks ago and was using it with net10 after unlocking the device for other carriers than VZW. I found the instructions on XDA (http://forum.xda-developers.com/showthread.php?t=2166542) and it worked like a charm.
Two days ago I went back home to Germany and in joyful anticipation i popped my german O2 sim into the phone. To my surprise the phone did not connect to the O2 network. Since I've read about Germanese experience with O2 in Germany (http://forum.xda-developers.com/showthread.php?t=2017987) I was positive it'll work. However, when I set the network mode to "GSM/UMTS" and try to select a network manually, the list of available networks is empty (see screenshot).
@Germanese: Am I missing something?
I continued fiddling with the parameters available in the hidden radio menu (dialing *#*#4636#*#*), tried all options on the "preferred network type" parameter and changed the radio band from "USA band" to "Cellular". Still no connection.
Then I've proceeded with unlocking the bootloader and installing CM 10.1 to check if I get a few more options. Surprisingly in CM 10.1 I wasn't even able to choose a network provider manually, the option simply doesn't exist. In the hidden radio menu (which can be accessed in the same way as in the stock system) on the other hand the list of radio bands looked slightly different: I was offered to choose between US band, Japan band and two other options (can't exactly remember what it was and already reverted back to stock), while for all of them the actual frequencies were displayed. It caught my attention right away that there wasn't an option for a 2100Mhz band (which is the frequency all German carriers use). Needless to say I didn't get it working on CM 10.1 either.
Anyone can point me in the right direction?! Maybe flashing the AU radio from xt905 firmware? Although Germanese pointed out it works just fine with stock ROM?
Any help is super appreciated!!!
All the best!
Henry
Dear Henry,
My Girl is actively using Razr M (Verizon Model) In Germany Munich.
The stock Rom works but has very Poor signal as you see yourself.
We got her working nicely with the Australian Radio.
The other way was to modify some codes with the RadioCom But not advisable if this is your first run.
So yes the best thing to do is to do the AU Radio Flash Mod.
Hope this helps...
Thanks for the fast reply! Do you have a link to the RadioComm Mods you're talking about? I've used RadioComm for the "00" NV tweak to get the phone working with net10 in the US - so I have a little experience
Wooohoooo!
AU radio is working! What a hike
Can't say anything about data for now as I don't have a data plan activated yet. However, signal strength is good and call quality is absolutely fine.
Cheers
Henry
data working, but only egde/gsm
Dear All,
Got myself a data plan with O2 two weeks ago and it works on EDGE/GSM. However, I can't use UMTS/CDMA network.
@Germanese: How did you configure your girlfriends phone to make 3G work?
The NV value @8322 is still 00 - the factory reset I performed after changing it didn't have any impact on this setting. I've tried to change the preferred network type in the *#*#4636#*#* menu without any success. The radio band selection holds only one option: GSM/UMTS band.
Any other ideas?
Thanks
Cheers
Henry

Hello dear XDA Community,
I have an american Nexus 6P (used with Verizon) which is currently used with a Russian cell carrier "MegaFon"
I had troubles with connecting to their LTE, for some reason my phone just wouldn't connect to the LTE and only stick to HSPA or HSPA+ even though an iPhone near me gets LTE signal just fine, the SIM card is fine in the other phone as well. So I started messing with my phone to find if I could fix it, first I started with going back to full stock, that didn't help, the phone still only accepted HSPA signal. Then I tried multiple ROMs and Stock Images but the issue of not connecting to LTE persisted. Then I found out about *#*#4636#*#* menu (aka Phone Info menu) and I started messing with it, which again did not do any good until I hit the menu button and pressed Select Radio Band (P.S. please don't mess with those settings) where I tried selecting all 3 different "GSM/UMTS" Bands. I tried USA band, Band mode 6 and Band mode 7, but this just broke down my signal completely, I cannot connect back to the carrier network no matter what I did. I've tried factory resetting, flashing radio img's, flashing stock/custom. NOTHING HAD HELPED/WORKED
I'm now stuck with a phone that doesn't work at all, and I'm on business trip so I'm just pulling out my hair for messing with those settings in the first place.
Does anybody know a possible fix to this? How could I go back to what I had before even though I tried all kinds of forms of factory resetting the phone
I really beg for your guys' help
Thank You
EDIT: Found this http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347 gonna try that right now
EDIT2: That modified ROM helped! But I still don't get 4G
Have you tried removing the SIM card, rebooting the phone, then going into the Phone info menu and setting the preferred network type to LTE/GSM auto (PRL)? Maybe afterr another reboot with the SIM inserted the phone will connect.
Also check the APN settings -- they might have changed.

I think I've tried it, I'll give it another try after seeing if flashing this one ROM where you can select Auto Band in 4636 menu that I linked in the edit would work.
APN settings were fine.
Thanks
EDIT: That ROM helped! But I still don't get 4G
Looks like the post you linked should do the trick. Good luck!
code in Huawei *#*#4636#*#*
I have the same problem. My Huawei is Portuguese and the sms work and the internet to but no signal radio. Wen I dial a number tells me no radio found. Can somebody help me? Thanks
Hi guys...
Could really use some help here...
I was facing some issues with my 4g network... So I went to the *#*#4636#*#* menu and turned off radio etc...
I usually did this when my 4g network would give me problems.
However last time I had some time in my hand and decided to see what other options are there. SO I went to the Radio Band option and I don't remember what I chose but ever since then my phone can detect only 4g on either sim. No 3g no 2g.
I went to the radio band menu again and have tried selecting all options but nothing seems to work... I get USA band and then BAND MODE 31,32, 33 all the way up to 42...
Please help me...
I am new to posting in the forum. So I can't figure out how to attach images.

i had this problem i was also playing with the radio bands in the service menu follow these steps and surely you will get 2g coverage.
1. make sim 1 and as primary and then open service menu by *#*#4636#*#*.
and then select radio bands from top right corner and select radio band 42
2. now switch the sim cards in the sim slot and repeat the whole process from step 1 surely you will signals on both sim.
