Unable to get 4g to work - droid RAZR Maxx - xt912 CDMA - Motorola Droid RAZR

I’m a previously proud owner of a Droid Razr Maxx - xt912 CDMA version.
I followed Matt’s instructions on flashing the December JB leak with root. It worked great since January until recently…I’m not sure what happened but I lost the LTE part of my Baseband. Now I have can’t get 4G. I tried following someone’s instructions which included using RSD to flash an older ROM (was supposed to correct my baseband). …ended up bricking my Razr. I managed to restore to stock JB using matt’s “batman” utility using option 1….still missing LTE in my baseband.
I don’t even care about being rooted anymore, though it would be nice. I am just trying to restore my 4G. I live and work close to Boston and have always had strong 4G connectivity.
Steps taken
Did the *#*#4636#*#* and made sure my preferred network type is set to LTE/CDMA/EvDo/GSM/WCDMA
In My Mobile Network Settings I made sure my preferred network mode is set to LTE/CDMA
I did the *228 and *22899 and received on screen confirmation
I’m leading towards it not being setting related but the fact that I am missing the LTE portion of my radio as shown in my phone baseband version info below, however, I have not found a way to get the LTE back on the phone.
Does anyone have any ideas?
Any help would be greatly appreciated.
Current phone info:
System version
98.72.16.xt912
Android version
4.1.2
Baseband version
CDMA_N_05.21.00r

I have the same issue. Has anyone fixed the problem?

maybe try to flash a different 4.1.2
so you attempted to root it didnt work and knocked out your 4g? that sucks , did you try a factory reset ? maybe try to get another stock rom to run instead of matts? maybe thats part of it
any way i hope you get it working cheers.

GSM Problems: Help please.

Im having the most annoying problems with my photon
all used to work well, signal bars were great.
then one day i had a fail to boot message, so i flashed this SBF
http://forum.xda-developers.com/showthread.php?t=1202666
And nothings been the same. It seems my radio/baseband is messed up
I have it set to GSM Only as usual
but every now and then it just loses signal ( i think when it switches towers) and wont come back till i reset it. and other times itll switch to 'Automatic' and think its a CDMA phone.
And the most annoying part is most of the time ill have 'signal' but little do i know no text messages are getting to me. and no phone calls. and if i try a phone call it hangs up a second in. These problems are all intermittent, itll suddenly just work after time, then stop after time. I thought it was my SIM Card but all is functional 100% in a different phone. I hope i dont have a sudden hardware problem in the phone itself.
I tried flashing to old SBFs, factory resetting nothing works
Ofcourse I skip the handset activation at the beginning as im in canada (GSM) and i cant seem to 'factory reset' the radio or use any of those codes because im in Canada and it asks for a passcode that i dont have
if ANYONE knows nething i can do pelase help, because its looking like i have to ditch the photon
I flashed my phone with that too, but no network problem after that.
I guess you have tried already to flash again. I'm also on gsm only.

im thinking my phones radio is physically crapping out.. ah.
Perhaps that SBF borks GSM usage? Have you tried one of the very first SBF's that have been put out?
i tried 154_5, and 198_6, not sure if they are 'official', but both have this problem.
do u know of any other ones, or of some factory rom
id try those deblurred custom roms, but they have this wierd bug of not showing signal bars with GSM, aka no matter how good my signal is, the signal bar will always show 0 in those roms
I have been searching for crazy for the past week becuase i have had the same issue.
UMTS 3G radio stopped working, but i have not been able to find any 154 sbf files to flash.
I have to keep GSM mode only, and my battery life is terrible. Battery dies after 7 hours with NO usage. The only thing i have not tried, after flashing all kinds of software, is doing a nandroid backup on another Photon and flashing it on my phone. Will try it right now ad report back.
thats a good idea, especially if the nandroid u take is from a STOCK completely untouched Photon, i just wanna go back to how it was when i first got it
let me know how it works out! so we can upload it
i have the 154 sbf if u wanna try it:
http://www.multiupload.com/FNZKNV0T3G
ps: try flashing a rom from the dev section like that 'Home Base' one, i will try later
THANK YOU! I have been trying like crazy to find the 154 one. Im flashing the nandroid backup, but im doing it over the advanced settings, sine the /boot folder is giving me an error while checking "MD5 sums". It says error while flashing boot image. All other folders restore ok. I´ll post back.
ps. I´ve flashed HomeBase and Alien rom and apparently they do not touch the basebands.
considering that sbf that broke it for me is an official sprint update, it means sprint/motorola messed it up, knowingly or unknowingly, should we make it clear to them (to matt on those moto forums). not many users probably use gsm w sprint/photon so the problem isnt wide spread
i think the one that was working for me was soemthing even before 154, i cant remember if i updated my photon once, 194 is the third OTA right?
Im not very sure, but i work for Sprint, so i´ll check it out tomorrow and let you know.
Anyways, my friend with the Photon, the one i used for a nandroid backup does not have any issues connecting to 3G Gsm networks. It is very odd indeed.
[Edit] My friend´s Photon and mine do not have the same baseband version after the nandroid backup, so i guess it doesnt touch it. We need to figure out a way to get the sbf for the baseband,
whats ur baseband version?
ill check mine
if u work for sprint thats a bonus, dig around tomorrow!
my baseband is n_01.28.05s.fk i am currently doing an OTA update that has been ongoing for a week. im still only at 23%. so there may be a newer version.

[Q] [Help][Stock AT&T 2.3.4 Build 4.5.91]No network after *#*#4636#*#* > USA Band

[Q] [Help][Stock AT&T 2.3.4 Build 4.5.91]No network after *#*#4636#*#* > USA Band
Hi guys! Plz help.
I have AT&T Motorola Atrix 4G. Its SIM Unlocked and Bootloader Unlocked as well.
System version: 4.5.91.MB860.ATT.en.US
Android version: 2.3.4
I am using this mobile phone in India and had no problem at all with 2G and 3G networks.
Today I was going through *#*#4636#*#* > Phone Information > Menu > Select radio band > and selected USA Band accidentally. Thereafter I have no GSM network. I tried manual searching of networks and did a Erase data/factory reset in CWM recovery but had no luck. I tried to restore an earlier backup also but due to MD5 Sum Mismatch error I couldn't do it.
Please help me getting my mobile working again. Is there something which can reset radio frequencies of the phone? Any idea what should I do now?
Thanks you so much for your help.
Hey there!
I had same issue a while ago and didn't have unlocked bootloader back then.
I simply re-flashed stock firmware from this thread and everything worked fine. If you do this then make sure you chose right one (For you first one should be right), If you downgrade to 2.2.x you will hard brick your device. Just keep that in mind.
By the way now I'm using [CM7 ROM][24/12] --> Neutrino ROM 1.4-S <-- [53mb] and there in settings you can choose whatever band you like unlike in stock AT&T firmware from *#*#4636#*#* you can chose only USA Band. There must be other roms what support this feature too.
I'm sure there are other ways to fix this issue but this is from my expierence.
Good luck!
PS I did that in first week when I had Atrix and it was my first android device. I managed to fix it, I'm sure you will fix it too

Hi mm166,
Thank you so much for your reply and I do think a re-flash only can fix my mobile. Since I have Bootloader Unlocked so I think I can't use SBF method to flash stock 2.3.4 and I can only go for fruitcakes. I am now downloading ATT 2.3.4 Build 4.5.91 fruitcake and I hope it will fix my mobile
I am woundering if flashing ATT radio .91 from following link will reset the files responsible for holding network settings and can fix my mobile ... but I am not sure so can't go for it
http://forum.xda-developers.com/showthread.php?t=1163009
Update:
I just flashed "2.3.4 System and Boot NO Webtop (Updated Newest Script)" fruitcake after Clear Data/Cache/Factory Reset but still no network
I think I have lost my mobile just because of accidentally setting to USA Band.
Any help please!!!!!
Well, I'm still newbie on Android devices. I'm not very long with Android device but I'll try give you few advices. Keep in mind that I could be somewhere wrong:
I think new script: [Batch/Script] MFBSR - Moto-Fastboot: Stock Restore could help. Worth trying. Fruitcake didn't restore everything.
I used RSD SBF flash and I think it doesn't matter if bootloader is unlocked or not (maybe someone could confirm that?) if you flash same firmware but that's somewhat risky (better don't try this). But I did that and everything worked great.
Other way to fix network issue could be flashing custom rom. For example this. I added screenshot from settings. Edit: No, I think I'm wrong. That's not right thing.
Solved!!!
Hi mm166, thank you so much for your reply
Before reading your message I did a trick and it worked for me. I just flashed ATT Basband/Radio N_01.77.36P FruitCake through Rom Racer's CWM and after reboot my phone was able to find network as it should be
Since my phone's BL was unlocked so I was not supposed to try SBF flashing to prevent it from hard brick. And, just flashing Stock ROM FruitCake was not resetting its radio settings i guess ... and flashing particularly above mentioned radio files just replaced the older one and once again my Atrix started to breath
I hope this may work for other guys too who are facing same kinda problem of not getting network after accidentally setting the radio to USA Band. But a Full Wipe/Factory Rest/Data/Cash/Dalvik Cache Wipe is needed.

[Q] CM9 Unofficialy

If there is already a thread for this then sorry but i couldnt find any....
Was wondering if anyone has tried using it or is using it.reason asking is because im having a radio issue with it.it connects to 3g at first then i either wind up losing data connection or losing signal alltogether even tho im in a full signal area.It really does this when coming off wifi.
I have tried using airplane mode and that seems to help to a point but most of the time i wind up having to reboot it inorder to get my signal and data back.Is anyone else having this issue or ran it and had the issue? is there a fix for it or something i need to do on my end to stop this?
I am currently using J.Y.Daddy's GSM patched CM9 (17/05/12 build). I personally have not had any issues regarding the radio, and my connectivity for both 3g and wifi has been fine.
I think this is a fairly common problem for some people, so perhaps you can try asking in this thread here: http://forum.xda-developers.com/showthread.php?t=1552166
I think we should get as much info as we can about all handsets that have this problem, then keep an eye out for any commmon elements that could be the cause.
I am using a XT910 (Asia.retail stock rom on purchase...unsure as to HK region or other as I lost that nandroid backup after a corrupt drive), I have updated my fastboot file to the most recent Asia.retail I could find (the non HK one from memory), and I live in Australia (in case that matters).
Which fastboot are you using, and GSM or CDMA?
Hope I can help.
Im using cdma....stock rooted verizon with bootsrap touch....

Hmm, ok, as we do not have the XT912 in my country, I may not actually be the best for advice here.
I have a feeling that the majority of the radio issues are with the CDMA phones. If you are on stock rooted, then I think it is safe to say that the fastboot files won't be the issue here. Where abouts did you get your copy of CM9? Is it from the site itself, or here on the forums?
Only other thing I can think of is that I think I vaguely remember reading somewhere that the razr bootstrapper app was causing some problems with some users.
Have you heard of/tried using SafeStrap as an alternative? IIRC it is another version of a reboot recovery which is exclusive to the Verizon XT912 and many people who reported issues after flashing roms with bootstrap did not encounter the same errors with SafeStrap.
When I get home from TAFE I will try to find the links where I got this information from and provide some more help! CM9 is a fantastic rom which I cannot recommend enough, so let's try and figure this out!
Yes i have originally used safe strap v1.9..i have the same problem with aokp.ive wiped 4 times before install n still same problem.
Could it be not wiping enough or right places cause when i had my sgII there was a custom wipe zip inorder to properly wipe the areas needed.they had said cwm had caused issues while using factory wipe data/cache...
Alot of people didnt know cm9 was even avalible.i love cm9 personally.have used it since my hd2 days...i know there is a patch to make cdma roms on gsm i wonder if there would be able to have a patch for gsm to cdma?
I have installed from stock rooted, eclipse,black ice....have tried everything i know of....miss my cm9

[Q] Cannot connect to any 4G Signal

Hi,
I recently upgraded my ROM to HyperDrive which has been working great. I have attached an image of my specs... During the last few months I've seen my phone connect more and more to 3G instead of 4G, now just recently my phone no longer connects to any 4G at all even if I'm right next to the tower. Does any one have any ideas? I'm thinking it could be a localized problem with perhaps some of the towers, but I want to check everything on my end.
Also I was thinking about upgrading my Radio to see if that might help, my question is based on the information that I've provided with the attached image should I be able to upgrade my radio without having to wipe any data, or loose root? I've also wanted to upgrade to HyperDrive 10.2 but if I upgrade will that wipe my data too?
Thanks for your help!
p.s I have Verizon

Check your mobile network settings.should be able to dirty flash 10.2 and not loose your settings. But you could always use tibu then restore.

[Q] Razr XT912 on PP with working LTE, no voice/sms

I'm a new member here, I have done extensive search on this issue and have not found a solution yet.
My phone is Droid Razr Maxx XT912 that was flashed to PagePlus 3G months ago. I used a thread on Howard Forums that details the process for flashing various Droids to PP 3G.
It worked great, no problems. Last week I installed CyanogenMod 11 and it still worked good. Yesterday my PP LTE SIM arrived and I began the process of getting it to work on 4G. Settings in Mobile Network Settings are as follows: CDMA Subscription is set to RUIM/SIM, and Preferred Network Mode is set to Global(CDMA/EvDo/LTE/GSM/WCDMA. I tried a few of the modes, with same results.
The issue is that LTE works great, but I have no voice or SMS. MMS works fine. I have been back and forth with PP support, they programmed it for 4G and they say everything is correct on their end, which it probably is.
Is there an obvious setting I'm missing here? Again it is running CM11 with SafeStrap. Installing CM would have fully erased the 3G flash and settings, is that correct?
Thank you!

Installing CM has nothing to do with the flash, I think your best bet for it to work is to uninstall everything including safestrap, boot into fastboot, and RSD It to this: http://rootzwiki.com/topic/13566-how-to-droid-razr-return-to-stock/ This is the only known way to restore the 3g settings you flashed the onto the device. Make sure you download this update: http://sbf.droid-developers.org/download.php?device=9&file=156 and not the Blur_Version.98.72.165.XT912.Verizon.en.US update, because the latter has no way of rooting it. Sadly, the only way to get your phone to work is to wipe it completely. Good luck!:good:
Thanks for the reply. I decided to try that about an hour ago, figured out how to uninstall safestrap, then used RDS Lite to flash the stock ROM (it was the same one you linked to). Now voice, sms, and 4G data are working flawlessly. The only drawback is that I'm back to the unrooted stock ROM. If I would install CM11 now, should it stay working or was there an issue with CM? I am assuming the 3G flash had affected files that are not part of the ROM?

CyanogenMod ROM has nothing to do with the service. You should be fine installing CM. If you need a root tool, use this: http://forum.xda-developers.com/droid-razr/development/droid-razr-utility-xt913-jellybean-t2861798 and install safestrap, and then install the ROM of your choice. It doesn't matter if it is Stock Slot or Slot 1 etc., it should work fine.:good:
It was just the leftovers of the previous 3G flash that caused the original problems.
I got my PagePlus 3G flashed XT912 onto PP 4G LTE with no problems by flashing the phone back to stock with RSD Lite and the .165 update. I then (after activating the LTE sim with PP) rooted, installed Safestrap, and installed Axxionkat. The one thing to check on any rom is in Settings>Data>Network>CDMA+LTE/EvDo.
