Advice for fixing my radio (non-ICS related) - Motorola Droid RAZR

I currently am in London, so I used radicomm to unlock my international bands (thanks to help from cellzealot and jimmydafish.) This is pre-ICS OTA. I have 2 Razrs, and both are now working for voice and text using the O2 network in the UK.
My problem is that on one of the phones the radio will not pick up 3G data bands. And 2G is painfully slow (1000X slower than 3G.) The second phone works perfectly on 3G. I know it is a phone/radio issue, since when I swap sim cards the issue remains. Both phones worked fine in the US on 3G and LTE prior to he trip.
There must be some setting I changed that turned off the 3G in the first phone. I remember when I first put in the UK sim it picked up 3g, but by the time I finished messing with settings to get up to work it only picked up 2G. Again, the second phone I set up (once I knew what I was doing) works great with 3G.
I have checked:
1. Ensuring I have the correct APN.
2. Operator selection in Mobile Network Settings (shows only 2G options on bad phone, 2G and 3G options on good phone.)
3. Radiocomm 1877 setting is correct.
4. Radiocomm 850 and 441 are correct.
5. Preferred Network st at either WCDMA preferred or GSM only.
I think my initial problem stemmed from "Phone Info's" menu: Select Radio Band" where I selected USA GSM bands. That was a mistake, and cut off all data entirely until I reset Radiocomm 441 to 00FFFF, which got me back to 2G but not 3G.
Any suggestions, or should I just wait until I get back home and apply the ICS OTA, which will hopefully reset the radio?

I would recommend a factory reset/wipe, which will reset any changes made in the Phone Info menu. If that doesn't fix it, then reflashing the stock firmware and radio image will absolutely reset the device completely to a default configutation.
Then you can start over and reapply the NV edits and it should work like your second phone with all bands.

Thanks, I definitely appreciate all your help. I'm thinking that my next step is to try to side load ICS and see if that fixes the radio at the same time. If not I can use Matt's utility to go back to stock GB. I do hear a lot of people struggling with side loading and I'm not sure if the changes I've made could cause the OTA to fail.
I was just checking first to see if there might be a simpler solution such as fixing or flashing the radio... but it sounds like there is not.

Factory reset/data wipe is much simpler than any other option and is a recommended part of either flashing back to stock or running the update to ICS.
The changes you have made to the radio NVM via either RadioComm or the Phone Info menu will have no effect on your ability to update to the leaked ICS builds and any changes will be overwritten by the update when the radios are updated.
The ICS update will, in fact, have the same string in 1877 that we manually edited for GB. That's how it works and enables the full function of the radio.

[Solved] Radio?

Hi
OK, I have just received my Atrix, and am having trouble. Basically, it will not connect to mobile data.
It is an AT&T model, unlocked to all networks by the seller. I can make & receive phone calls (now I've found how to skip Blur setup), and have entered the correct APN settings, but it refuses to connect.
I am assuming this is a radio/frequency issue. Are there any radio images that can be used to correct this, so I can use this in the UK? On the Defy there is an app called "baseband switcher" which can install the correct info for you.
---------- SOLVED ----------
Just a quick edit to show this issue is fixed.
I am unsure what fixed it. I have performed most of my testing at work, and found that the issue here was a problem with my provider (they were doing maintenance in the area). But it didn't work at home either, initially. I have flashed several radios, modified pppd-ril.options and replaced libmoto-ril.so. Something out of these has fixed my issue.
If I get chance I will remove some of the mods to see if the issue comes back, and post the results here for anyone else who comes accross this problem.
By the way, this has only fixed the issue of no 2G data. 3G data on 900MHz is still unavailable, as far as I am aware. If anyone knows how to check which frequency is currently being used, I can check this further, otherwise I think this is the best we can hope for at the moment.
Hi
Does anyone know the answer to this?
Can I flash a UK/European radio on this (AT&T) Atrix? I have installed Aura, will this make a difference? Are there "fruitcakes" available for the radio, or must I use and SBF?
I have tried to research this through the site (and google) but I can find no definitive answers. All I think I need is a 900/1800/2100 baseband. I definately have the correct APN settings, and mobile data has worked while I've been out and about, but it is very patchy and I am not getting mobile data in places I know have good signal, and am noit getting 3G in places I used to.
I had this same problem on my Defy, and this was easily fixed using the Defy Baseband Switcher app. Selecting a UK baseband fixed all my issues then, so I expect the same now.
Please help
Thanks

Hello
I'm interested at the answer too. I have bought AT&T version from US and imported it to Europe.
The problem for me is that I need Atrix to use 900MHz 3G. I can use 2100MHz 3G but when the 3G is build using 900MHz, Atrix is not able to use 3G, only Edge or GPRS. I have other phone with 900MHz/2100MHz support which I use to verify existence of 3G service.
I have tried with radio version N_01.95.00R which did not work with 900MHz. Just couple of minutes ago I installed N_01.100.00R (CWM zip), haven't yet tested it with 900MHz.
I have seen reports from users owning Atrix, that they have been able to activate 900MHz 3G support by installing N_01.95.00R or N_01.97.00R.
If N_01.100.00R does not work, I''ll try N_01.97.00R and after that I don't know what to try.

Thanks, that's more info than I've managed to glean from my research.
I'm also on a network which uses 900MHz for 3G (in some areas at least) so this may be my problem. I'm currently on baseband N_01.77.15P. If you wouldn't mind letting me know once you've checked I'll wait for you to report back about
N_01.100.00R.
By the way, does anyone know if there are these "fruitcake" things for radios, or do they have to be flashed from SBFs?
Just FYI, I got impatient, and work has been quiet, so I tried myself.
1.100.0R and 1.95.0R made no difference for me.
I also tried an international 1.97.0R SBF, and this gave me an error while flashing... was quite worried till I pulled the battery and it booted back up fine.
I just want to add, here, that if I manage to get 3G reception I can use it fine. However I don't get 3G in very many places, including ones which worked perfectly (full signal) on my Defy. Also, as soon as it tips over to 2G in these places, it shows the "G" icon but does not allow any traffic.
As I said, this is exact problem I had with my Defy when a ROM I installed changed the baseband to a US one from a UK one, and it was fixed as soon as I changed back. So "all" I need is a baseband which will install on my (BL unlocked, SIM unlocked, Rooted and ROMed) AT&T Atrix which is compatible with (O2) UK bands (specifically 900MHz for 2G & 3G and 2100MHZ for 3G only).
I tested with N_01.100.00R, but no success.
I don't know anything about "fruitcake", but I have installed new radio versions either from sbf with RSD Lite or from zip-files using CWM.
Where to find radio versions made for Europe/international use?
I have an AT&T Atrix in Germany, everything works out ok. Try following:
Go to http://forum.xda-developers.com/showthread.php?t=1163009 and flash the radio from there.
In your stock dialer, dial *#*#4636#*#*, choose Phone Information, Set preferred network type to "GSM auto (PRL)" or "GSM Only".
Before all that though, make sure you have the correct APN, it'd be a bummer if it's that simple..

Hi
Thanks. I have checked the APN settings so many times now that I could probably recite them by heart I have also installed an app which sets up the correct settings for me, so I'm pretty sure they are right. From *#*#4636#*#* network type is set to GSM auto, and "GSM disconnects" says "fail because Unknown Data Error".
Which radio from that post, BTW? The AT&T .91 one?

Yep, that's the one I'm using.
Try flashing that and see how it goes. Though data should work regardless older / newer radio; have you tried calling your provider?
Nup
Flashed the linked radio, and it made no difference.
By the way, I finally found where the "Select band" item was, it's in the 4636 menu, phone info, menu key, select band. This shows only USA.
I think I may try flashing the French fruitcake located here just to see if that fixes it. Orange France uses the same frequencies. I know it's stock, but I can try flashing a custom ROM after. I just want to get this thing working now...
Also, there is a post here which seems to suggest a method to fix it, but I am at work and it's too much hassle to set all that up here.
I tried to flash couple of international sbf's but none installed, sec_exception febe 35,35 was the problem.
Then I tried to install Bell radio from bellradiolatest.zip using CMW. Now I have version n_01.77.30s.qn, haven't tried 900MHz yet but 2100MHZ is working as it was with other versions.
4636 menu shows me also the USA Band, which is only option, cannot be changed.
After I have verified that this n_01.77.30s.qn ain't working, I'll try AT&T .91.
I'm using Cyanogenmod and prefer it, I just can't stand the original firmware or something based on original one. For example, week starts from Monday here, in CM I can choose it but US based firmwares week starts from sunday and cannot be changed.
I can confirm that flashing a French fruitcake doesn't work, results in flashing red led. Restored from backup, back to square one.
The Atrix from AT&T does not have the ability to utilise the WCDMA network on the 900Mhz band.

Never heard of a carrier disabling a network they already have, but why would you be worried?
That sucks!
Anyway, the reason I was wonderring is that I cannot get a 2G data connection either. I have been told now on another forum that this is not the case, and I should be getting 2G data. So it seems the phone cannot even make a 2G data connection at 900MHZ (this network only does 2G at 900MHz, 3G is at 900/2100MHz). In *#*#4636#*#* it shows DcAtivatingState for ages, then goes inactive with "Unknown Data Error".
When I can get a 3G signal it is fine.

Could you type the whole thing out? Also, check your apn settings
I am absolutely certain the APN settings are correct, I have checked them over and over, set them using an app, and verified against my previous phone as well.
State: Dc ActivatingState is connecting to [ApnSettingV2] giffgaff data, 1357, 23410, giffgaff.comm , , , , , -1, true, -1, 0, 0, *, IP, IP

It sits at that for a long time, then goes to

I have also just had a reply on my operator's forum from another user who says he had exactly the same problem with this phone.
Now it's just gone into DcActiveState, and says the connection is available. However, nothing gets through. It reckons it's sending and receiving PPP packets, but I can't ping anything, can't nslookup, and obviously can't browse.
Just tried with my old phone, and everything looks the same (when restricted to 2G only), and it operates perfectly. So it is the phone. I checked the APN settings again, before you ask, and they are identical between devices.
I did read something about the stock AT&T firmware blocking other APNs, but that can't be what's happenning here, can it? I mean, it works fine when it can get 3G.
Right, this is getting irritating.
I just flashed a stock 2.3.4 fruit cake to see if that helped. I added my APN settings, and couldn't connect. Set it in WCDMA only and it got a weak HSPA signal, went through Blur setup. Tried again on GSM auto and no joy, even when it hits DcActivatedState nothing gets through.
I am absolutely certain it is not the APN settings. I am sure they would not even allow 3G access if they were wrong, but with a 3G signal it works perfectly. But on GPRS (in several places, miles apart so on different cells) I can get not data connection.

Enabling 2G data connection purposely on the Photon

I feel really stupid for asking this, but here goes. I have a Photon, just got one of the T-Mobile SIM cards, activated it with the $30/month unlimited web+text+100 minutes talk time thing and I'm wondering - for my own purposes, mind you - how to purposely enable only 2G data on the Photon, if at all possible.
Now, at the moment I'm running the stock 2.3.4 ROM, unlocked and rooted so I could install the KDDI radio, and my T-Mobile speeds are consistently in the 5-6 Mbps range which is more than acceptable and I have zero issues with that service at the moment.
Having said that, and again for my own purposes, is there a specific way to get the 3G data connection switched to straight 2G/EDGE mode directly on this thing? I will be moving over to cybik's CM7 ROM here shortly and I can't recall (when I ran it a few days ago) if there's an option in the Mobile networks menu to switch from 2G to 3G. I was able to see the T-Mobile 2G network under the secondary menu as an available network, and I selected it but it still appears to be 3G.
Guess I'll play around with it some more, maybe there's a toggle on Google Play or something, just thought I'd toss the question out since I can't seem to locate such a toggle myself. DOH!!!
Update:
Installed that CM7 from cybik and it does have a menu toggle to directly enable 2G mode, works fine here for me (140-180 Kbps consistent, works great for streaming audio which I listen to frequently, iHeartRadio and a bunch of different police scanners online from RadioReference using Scanner Radio Pro). But I'm still wondering if it's possible to enable that with the stock 2.3.4 ROM directly, if anyone can offer any info, thanks.

It is for the atrix, but should be similar for stock.
Also you are correct CM7 has those settings allowed by default.
Also you can set the mode in the *#*#4636#*#* menu. Under phone information > CDMA Only = 2G ; EvDO only = 3G
Also: be careful editing the settings in the *#*#4636#*#* menu under the stock rom. It did it once and locked my phone on GSM and had to SBF to restore CDMA. Dunno why it did that but I have seen others have the same issue. IIRC i didn't even enable GSM it just happened when I entered the phone information menu.

I put cyanogenmod and now i dont have 3g.

Hello. I have an unlocked i717 and i have Claro Argentina.
In stock rom, i puted *#2263# and changed gsm to 850/1900 and worked fine.
Now in cyanogen 10.0 i have no 3g, no internet.
I have tried putting *#2263# and it doesnt work anymore.
I have tried chaging apn and, doesn't work anyway.
What can i do ? How can i acces to the same panel that i entered before with *#2263# to change bands?
Thanks
APN must be input exactly the same as the previous APN.
Also, it must be saved prior to leaving the setup screen, or it will be lost.
If the APN is correct, your signal will return ...g
I know that. Apn is ok.
Also in standard rom i DIDN'T have 3g until i change bands to gps 850 /1900 by the *#2263# mode (with same APN), problem is that now with cyanogenmode that *#2263# dont work anymore, and i cant change bands to 850/1900.
UODATE: If i put "Use only 2g networks" works fine.
Your input code is obviously a carrier function...
And if your current rom will not support the code change, then the obvious choice would be a return to the previous rom.
I dont know what rom you had before, but if manual entry of the APN fails, and the carrier code fails also,
You are likely missing the associated RIL's that accompany the radio baseband.
And in order to restore the radio interface libraries, you will need to restore your previous build, (it contains the RIL's)...
Or use a compatible, NON-AOSP build.
Cyanogenmod does not contain the libraries that were issued in your stock rom .....g

Sory im new to android, and i dont understand very well.
I know that the input code is a carrier function, what i don't really understand if why i i put automatic mode internet doesnt work. By the way, internet doesnt work but the icon of "3g" and "h" is there...
I know that i can return to the previous rom, but i would prefer to have android 4.1, default version is 4.0.4, and i also like cyanogen futures.
My before rom, was the samsung rom ATT, original.
I don't know whar RIL's are.
What is an NON-AOSP build?
Is there anyway i can use cyanogenmod ? If not, is there any other rom (non default) that i can use?
Thanks
AOSP stands for "android open source project "...
It is pure android software , that lacks the "skin" or theme that is applied from Samsung.
It also means that some dependent software may also be missing. RIL's for example...
Ril's ...or radio interface libraries, are carrier added software that allow your radio..(transmitter chip) to communicate with your network , or other networks around the world.
And if they are missing, will break function with their respective carriers.
My first impression was that you are missing these files that are present in a stock rom, but not present in an AOSP build.
And that is a possible cause for your data issues.
But your saying that you do see the 3g, and H icons ??
This tells me that your device does see the network, but takes us back again to the APN settings, or the RIL'S..
Having voice service, but no data, would indicate a bad APN....but you said it's correct, and I believe you.
Of course, you have data enabled ??
I'm not doubting ....just making sure.
3g and H icons are a good sign....but the carrier is not seeing the device on the data side..
And this can be caused by a number of issues.
APN's and Ril's ....
Then we move to much more in depth causes..like device ID numbers missing, and carrier lockouts.
I don't think we are at those levels, and feel that we need to test the rom theory.
If you are willing to revert to the factory rom, we can then verify your current rom as the issue. And if the problem persists...we look deeper.
If the stock rom fixes the problem ....we'll find a suitable rom that won't break functionality for you ....g
Edit: very late here , and I'll be logged off for tonight, but will be back in the morning and continue to help you if needed...g

In fact, "3g" and H icons are showed. There were also showed in stock rom and i had the same problem before changing gsm bands by putting the code. (3g icon but not internet). When putting the code and selecting first option (auto), 3g still doesnt worked, i had to change to manual select of gsm 850/1900.
Thats why i think there is a band problem. Because is exactly the same problem that i have now with cyanoged, that the one i haved with default rom before selecting manually 850/1900. Problem here, is i think cyanogen doesn't have an option to select manually the bands.
APN im sure is fine, cause i have checked all, (that was also the first i do in stock rom).
About devices ID number, once, when i pluged the phone to the pc, win 7 says that "the id number of the hardware was wrong" or something like that. I reinstalled drivers, and problem solved, i don't know if could be something of that.... (i still don't think so, because in stock version i had the same problem, as i have written).
I know that stock rom will work (only if i put manually the gsm bands).
So what should i do? Reset to factory rom and loose cyanogen ? (I prefer cyanogen, but if there is no solution to my problem....),
Thanks
PD: Also like i said, if i select 2g network only, icon shows "E", and i have internet.
Settings/wireless and networks/more/mobile network.....
You will find the manual network switch for cyanogenmod.
We have it for ATT also, but the network restricts us so it won't work. But should work for you.
I'm running CM9.1.0 stable ...
Also ....your radio baseband should not have changed by flashing cm, as the rom does not contain the radio image.
I would not flash a different radio image, as yours hasn't changed ....g
Yesterday night i have tried again with stock rom,
I noticed that in gsm 850/1900 shows "E" = 2g, the sane as cyanogen, If i change to wcdma 1900, it shows 4g and doesnt work, SOOO, i put another SIM of other company, and works perfectly fine in 4g.I ve called today to my company, and they told me that there was a problem with the antenna.
Finally, there was no problem in the cellphone, and i can use cyanogenmod, unique problem is beacuse of CLARO that is a fu****** ****.
Thank you
Glad to hear the good news ....
Happy flashing ....g
Yeah, lots of places use the 850 band. Especially where towers are far apart. Low frequency waves travel farther. Is Voda or Orange an option?

[Q] VZW Google Edition ROM 5.9 NO LTE

Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.

Should Rezound show signal bars with no SIM card?

Here's the deal, I bought my Rezound in 2012 and flashed it to PagePlus Cellular using CDMA WS.
I've used it and it's been fine, running CM10 most of the time. I just bought a Evo 4G LTE and switched to that. So I RUU'd my Rezound, and it says a SIM card is required, etc.. but there are no signal bars.
I go into About Phone > Network >
and Operater name is "Unknown," signal strength is "0", service state is "out of service."
Now, the question is, is that normal? Does the phone need a sim card to connect to verizon towers?
I don't want to sell it while it's not working. I did call up Verizon and they said the ESN was clear for activation though.
So if I sell it and the new user puts in a SIM card, will it clear up all the signal issues? Or have I done the RUU incorrectly? [I did it a couple times because it didn't work the first time (the SD card method, then I did fastboot method)]
Thank you!
That is not normal behavior and you may need to do some more work before you sell it.
Make sure all related network settings are correct for Verizon instead of GSM under Settings > Mobile Network menu.
Try entering on the stock dialer *#*#4636#*#* to access the hidden testing menu as well for the phone radio and verify it is on CDMA. If that code doesn't work on the dialer try it via an app like "Hidden Menus" or even "Battery Monitor Widget" by 3C (click "Tests" icon > Phone information from main page of app.)
Background: I broke off of my Verizon contract six months in and used my phone as a WiFi-only device (VoIP and internet texting apps) for the longest time. While I typically hid my signal icon and ran the phone in Airplane mode with WiFi toggled back on, I would occasionally turn my radio on to resync time and date to the cellular network. With no SIM in it clearly was syncing off Verizon CDMA signal still; I simply wasn't fully activated on the network any longer.
I just made the StraightTalk AT&T SIM card plunge the past couple of weeks and did an NV edit in CDMA WS as well, all alright on GSM. I am on the stock global ICS ROM at the moment, one I know could sync time on CDMA before. However, I cannot get the phone to switch off of GSM even in the hidden testing menu, even without SIM in... Likely has to do with the NV edits I made, and perhaps that may be your case too.
You *could* repurpose the sale as a GSM enabled unit... If it was even set up and working well as such. But due to the current technical issues of getting GSM mobile data above 2G I'd suggest to get it fixed and working back on stock CDMA for the consumer's sake if you can. Again AFAIK It should pick up a CDMA signal even without active service or the Verizon LTE SIM in, did so for over a year lol.

in the mobile network, I have it set to "CDMA / LTE" but I tried "CDMA only" and "Global" but none worked.
*#*#4636#*#* didn't work in stock dialer, it just disappeared when I finished typing it.
then I downloaded Hidden Menu, found *#*#4636#*#* in the list, tapped it, and it did nothing. I did some other ones and they did do something. I found htc diag mode, the same one I used to program it originally. I clicked read, and the phone number and min were blank. so I went to the prl and tried flashing a verizon prl file, then rebooted, and still nothing.
I'm going to try to RUU again and hope that solves it.
Update
I RUU'ed again, but still no luck..
Can anyone confirm whether or not, say you got a Rezound out of the box never activated, would you need a SIM card to get the signal initiated? I'm thinking either that's the case and my phone just needs a sim card to jump start it, or my rezound is toast.
