Can someone more experienced than me, please help me with this?.
I have an AT&T Atrix. I tried flashing some Latin America radios to it, like Retail Brazil and Personal Argentina ones (sorry, I can't remember the radio version number). They flash fine, and I get full signal and UMTS connectivity, but I don't have internet access. Phone shows 3G connectivity in the status bar, but it won't upload nor download data.
The reason I want to use these radios its because they were developed to be used in my area.
I can't understand why these radios kill my internet connection when other radios like the 01.97.00R works with no issues.
So, please, can anyone help me to understand why I don't have internet access with these radios?. Is there any trick I can do to fix this issue?.
I'm using the stock 4.1.8.3 radio (N_01.77.15P) now since it seems to be the most stable.
Thanks in advance.
Bump.
Please people!. Topics like "Why my Atrix is black?" gets more replies than my questions.
I'm really dissapointed. This is the fifth time I ask a question and noone gives a damn.
Now you see why people post questions in the development forum.
This is the rhythm of the bump!.
Btw, why is the Atrix black?
Dude, you had it coming. Lol!

Don't worry, it was a joke afterall.
Whipon, did you get your atrix fixed?
Whipon, Lograste arreglarlo?
Sorry to ask the obvious, but did you got your Access Point Names correct?
AT&T branded phones will have to manually get the AP configuration when used outside of AT&Ts network.
Let me know!

My APN settings are fine. I've switched radios through RSD Lite lots of times, and my APN settings remain there. There's no need to modify them.
I've manually configured my APN when I flashed 4..1.8.3, and its correctly set up for my carrier. Using 01.87.00R or 01.97.00R radios, my data plan works perfectly. But when I tried to flash some LA radios like Personal Argentina or Retail Brazil, while the 3G icon is showed in the status bar, I have no internet connection.
So I was hoping someone with more experience could help me make these radios work with an AT&T Atrix. Current stock radio works fine, but my signal strength suddenly drops very often, and sometimes I have no data and I have to reboot the phone.
I've recently flashed Jokersax's unofficial cm9 to my phone .... i only receive 1x.
I decided to flash spleef's [MIiui.us]MIUI/ICS port [unlocked] and i am receiving the same problem.
Same issue with all roms flashed from Kitchen sink.
Same issue with Paranoid Android, which is what i'm currently running.
When i flash my Stock backup, i get 3G back.
My unlocked bootloader was suppose to only disable 4G so i know for a fact i am missing something or doing something wrong.
I did some searching and found that a specific Sprint business PRL MIGHT help. I am not sure how i would get this PRL file on to my phone because i cannot enter edit mode by using the ##MSL# from the dialer. I've already added the PRL file to my SD card.
Please go easy on me if this info is out there already... i do a LOT of research (hours and hours) but sometimes i just can't find it and i know that people love making others look like idiots which is why i say this. I've searched forums that seem related to my issue/ROM and found nothing. I searched them with the keyword "1x", which is how i found the possible fix with the business PRL.
Thanks in advance for all help.
It might not be a problem. The stock roms, all except peetr's 2.3.5 rom, will incorrectly register the 3G icon on the bar. Check the your phone's network status. If it says CDMA- EVDo rev. A, then it is a problem that it says 1X. if it says 1xRTT then its fine as its just 2G
Exactly what post above says, also to flash to PRL you can't simply put it on SD card and use dialer codes like you can some other devices, you have to use QPST to flash it. If your really interested on flashing it theres a tutorial floating around here on how to use it, I personally run the 01115 business PRL

Thanks for your quick response, i really appreciate that...
BUT, Settings>About Phone>Status> Reads that the Mobile Network Type is "1xRTT:6"
So based off what you said i should be at least 2G speeds regardless of the indicator .... But what about 3G? I am not always around WiFi and could really benefit from the use of it since i can no longer receive 4G =)
Thanks again in advance !

Like photon4glover said, if you're and change the selection, you'll stop force roaming on Verizon's 2g network that you're PRL forces you to. If you cant get a good Sprint signal and you're roaming anyway, I suggest you flash a different PRL like w0lf215 said so that you at least roam on their 3G network. However, you may be booted from Sprint for excessive roaming

Thanks for the responses.
I'm having a hard time understanding why I have to flash a business PRL to get this working properly on every single ROM except stock. I've flashed several phones before without having this issue.
My settings are set to "Home" as suggested. I do not want the possiblity of something happening and having to call and deal with sprint because of some roaming issue. No offense to all the Sprit lovers out there.. but hopefully flashing this business PRL will fix this issue.... I must admit, though... this phone is not as "user friendly" as the others that I've flashed and played around with.
I also have a problem with MMS so I'm thinking about using a different ROM.anyone recommend a good well rounded Rom that works out of the box?
Again, thanks for the input

So on the stock rom you're getting 3G Rev.A? I'm just curious since the only custom rom I know might do that is Jokers kitchen sink.

MMS works out of the gate on the MIUI builds I do (latest is 2.6.29). Saw before that you were mentioning Spleef's MIUI...he's been doing AOKP and others for a couple months now. I'm doin MIUI solo now ( ) It's all good. The MMS issue you're probably having is due to an error in your apn-conf.xml file. It's edited correctly in most of the ICS roms except CM9.
If you're looking to do PRL, just flash skinny rev 1 or shadow rom, update your PRL, then flash back to an ICS rom.
It's not bad to work with...just gotta get to know it better. If you have any questions, PM me, and I'll help as best I can.
Hi Guys,
Quick question for you experts. I use my Rezound as a 3G device, because I am on Page Plus and not Verizon, so I am only looking for 3G Speeds here.
I am facing this issue:
I get full 3G data speeds on the Stock ROM and let's say the Vennasaur Sense 4 ROM, WITHOUT ANY SIM in the phone.
However, when do the same exact process to install Newt's XXX, I get NO DATA, until I pop a generic NON LTE 4G SIM, and then, I am only getting 1X Data speeds ...
Restoring back to Stock or Vennasaur gets me 3G again :/...
Now I know that most of you don't care or would know much about Page Plus and using a Rezound with it, but, can someone tell me some of the technical reasons or differences between the two ROMs I mentioned above, that might be causing this data inconsistency between them?
I am Rooted (Unlocked Bootloader), Stock Earliest GB Build, and when I flash any of the Sense 4 ROMs, I apply the GB Firmware update patch...
Any ideas guys? Thanks for all your help!
Maybe LTE was disabled?
Check network settings.
Thanks for your reply. LTE is supposed to be disabled, since Page Plus doesn't have 4G.
I think the key lies with the way the two ROMs telephony works? Venasaur doesn't need the SIM inside to make 3G work, while XXX doesn't get data, period, until I put a NON-VZW SIM and then I finally get 1X data...
I even tried writing the proper 3G keys using CDMA WS to the 9K port of the Rezound, but the settings are NOT sticking or saving. I want to do it manually, but the ##778# and the ##Program# menus ALSO don't work in the XXX ROM ...
I am sure someone has the right answers for this, please help guys! Thanks!
Not sure if this works. You can make a note of APN settings when you are on vanesaur and create a new APN on newt ROM with those settings. Sorry if this is completely irrelevant

After happily using my 'old' S4 on T-Mobile with HSPA+ since having the Note 3 as my primary line, I was naturally excited to update the baseband and unlock Band 4 LTE. However I noticed some caveats which I've now solved which will undoubtedly confuse everyone at some point.
Assuming you've got the correct APN for T-Mo (fast.t-mobile.com) and naturally install the SIM, if your phone is on global you will happily see working LTE but not so fast (no pun intended). If you call or text, it fails. If you quick check your About -Status in settings and look under network it will say say Unknown and not T-Mobile. Why? Essentially you're in LTE data only mode because by default the baseband is looking to connect to CDMA for everything else in the CDMA/LTE marriage that is Verizon unique, which obviously won't work here. The assumption otherwise is that you will only need GSM if traveling internationally so it never looks for LTE with GSM.
The quick easy fix is to drop out of Global back to the GSM/UMTS setting, which will bring everything back, network restored to T-Mobile, but now it won't use LTE again, lame.
Luckily there is a fix. Use the PhoneInfo app or however you prefer to get to the Testing App. Under device information change the dropdown to LTE/GSM (auto PRL). Toggle airplane mode or restart. When it comes up you should be on LTE and quick check settings again you'll see T-Mobile, and everything will work. So far this seems to hold pretty well.
EDIT: Note: This works for TW Roms. I have not had success in CM10.2. In CM I've only gotten LTE data (wrongly labeled Verizon) and nothing else. Doesn't even pick up my phone number regardless of settings used.
Can you send me the link to the TW rom you are using for this? Thanks!

Use this app, hit Device Information, and change the dropdown to LTE/GSM (auto PRL). Given the simplicity not sure you need much more of a walk through than that. A video would require a bunch of editing to blot out IMEI and phone #s.

I am using this app and it is great. When it works, it would show T-Mobile as Net. Op instead of Unknown. Only issue I am seeing is that 4G LTE signal is not so great over where I am at and once in a while it would drop to H+ and then get back to LTE. During that cycle, the Net. Op would become Unknown again. Wish there was a way to fix this permanently like tricky the SMS app to send GSM or whatever it is causing Net Ops to be unknown.

Couple of things. Remember as I started with the baseband in i545 when on LTE really wants to use CDMA as the default so when it's searching it's not going to obtain GSM as instantaneous As it otherwise would. Don't see any specific way of that getting patched ever as we're going against the grain of how it's typically supposed to be used. If you are on a fringy area for it, you may be better off just leaving LTE off, H+ speeds are practically the same anyway. Tmo is only using 3-5mhz channels for band 4 as they use other channels too so for us it's not going to be superfast like Verizon on average anyway.
My phone is in Global mode, I have fast LTE internet and calls/texting works just fine. I am using a Verizon S4 with MJ7 and a T-Mobile simcard. No need to change anything except the APN and switch to Global.

yep, cant really install anything on MJ7 since there is no official root even, so yeah, bone stock. Fastest I have gotten the internet to be was 25-26mbps download which isnt great, but for a cellphone is more than enough lol
So maybe the MK7 bootloader fixes this SMS issue...
How is this holding on for u ? I got it to work one time with hyperom and I restarted and it doesn't want to work. I did however get it working completely on a mj7 ROM and gummy kikat ROM. Weird.

so using the 4.4 gummy rom you were able to connect to LTE / HSPA+ networks easily? And SMS / MMS worked just fine? Upon trying with the MJ7 update, non-rooted, I could only connect to Edge services under the GSM profile. Using global would barely warrant the HSPA band.

Are you actually getting "LTE" or reframed 4G?
please school me how to change apn.
well let me give you a trick, flash an i9505 rom which you can find them here http://forum.xda-developers.com/galaxy-s4/i9505-develop
then flash any verizon kernel (because if you just flash an at&t or t-mob rom it wont reboot it will say triangle and not authorized verizon software)
dont forget to update your baseband to lastest then you can enjoy LTE (and fast) without any problems.
if you get and prop. issues while flashing international roms just change the "updater-script" first line to :
assert(getprop("ro.product.device") == "jfltevzw" || getprop("ro.build.product") == "jfltevzw"
then you can flash anything you want.
Here is how I did it

Running a rooted stock MK2.
any ideas?
My friend purchased a G900T that was broken for parts, which needed a new screen. Upon replacing the screen, the phone was functional, but he discovered that the IMEI number had been blacklisted on T-Mobile's network. We unlocked the phone to use it on ATT, and the device works fine on the ATT network, with the exception of mobile data. No matter what steps we have taken, putting in custom APN settings, we have not been able to get data to function.
Does anybody have any suggestions as to what might be causing these issues?
Thanks a lot in advance! :good:
Have you tried to flash an AT&T ROM & AT&T Modem?
Or are you still running T-Mobile ROM & Modem?
Still running the stock Tmobile rom and modem. I thought about switching to ATT rom and modem, but I wasn't sure if that would brick the phone or if it should just work with the stock Tmobile modem. Can I just flash an ATT rom?
Just make a Nandroid beforehand.
T-Mobile S5 comes w an unlocked boot loader so you shouldn't have any problem. You put in an AT&T SIM card right?
You do not want to flash AT&T firmware on a Tmobile phone unless you are looking to brick it. You can however flash ROM's from Unified S5 threads (900F, 900T etc.) that are open to multiple model phones.
So if I flashed one of the unified roms, would that change the modem at all? I was thinking that it wouldn't be part of the package. Would just flashing an att modem be a terrible idea? I am using an Att sim card. Thanks for the ideas so far!
No, do not flash an att modem or ROM on a tmo device. It won't work, and it is not meant to work.
Does your subscription have an active smartphone data plan?
Are you getting any data connection (E, 3G, or 4G)_and you're not able to jump on the LTE or just no data at all?
If the answers to above questions are yes, there are a few more things att checks for before authenticating data use on a device.
These fields need to look exactly like this:
ro.product.model=SAMSUNG-SM-G900A
ro.product.name=klteuc
ro.product.device=klteatt
ro.build.product=klteatt
This information lives in the build.prop file of your android OS and you're gonna have to look up how to back up and edit this file. Start off here http://forum.xda-developers.com/showthread.php?t=1948558 and keep on reading. I kbow this is exciting and you want to make it work quickly but it is not so simple. So reading and researching are your best friends.
Best of luck,

Okay, thanks for the info! We are just plain not getting any data at all, and the user does have an active data plan with ATT. MMS messages are not even able to be sent or received. So in this instance, do you think modifying the build.prop to match the example you gave me would resolve the issue? I'm pretty comfortable working with the build.prop on the device and just working the the Android OS in general so that should not be a problem.
So I guess checking the APN settings won't be a bad idea:
