So I'm in Bangkok this week, and I have my unlocked stock rooted Infuse 4G with me and my Tru Mobile Roaming SIM won't connect to the right network because the stock rom points to the default AT&T roaming partners, and when I try to manually select a network the manual selection is greyed out.
I read somewhere on here that going into app SamServMode and selecting debug and Debug Screen and Phone Control and Network Control then select Manual it doesn't allow for selection.
The issue is the phone is preferring a different network than my SIM has a roaming agreement with, so I need to be able to manually select. Anyone know of a solution without changing roms?
Thanks!
Anyone? I bought a local DTAC sim and it works fine since DTAC is the official AT&T roaming partner the ROM allows hooking on to it, but still can't use non-DTAC sims as the rom doesn't allow manual network selection
Bump.
Can anyone help her?

So I'm heading home to the states in 24 hours... but I do think this is an interesting topic hopefully someone can assist with. Seems that even when unlocked, a carrrier cannot be manually selected, leaving roaming limited to the carriers att allows even when using another carriers global sim. Seems a limitation of stock rom but is the first time I've seen this on a phone.
Bella i've got the solution for you...
Flash the rogers modem..
The att modems have this feature lockedout, so any changes revert back.... I can confirm that the rogers modem gives full access to changing the network and it does stick....
Do so by pressing *#2263# with rogers modem.... You can then manually select the network to lock onto.

Nice! Wish I'd known this last week, hehe. Just walked in the door back home from my Tokyo flight, dohh.
So how do I get and flash the Rogers radio? And why does typing this bring back memories from Airplane! ???

Just flash via cwm and you will be good to go...

Do I need to install modded 3E recovery first, or just flash it from a stock rooted state in CWM?
I've not flashed a new radio before on this phone, so a step by step would be much appreciated.
Thanks!
Just out of curiosity do custom ROMs have this limitation?

Well I keep finding things that are limiting my experience with this phone. It's definitely been negative overall in comparison to my old Inspire 4g, which was so open, with many ROMs available, and none of the locked down attributes of this Infuse 4G.
So is it really the radio, or is it the ROM? And what are the upsides\downsides to flashing the Rogers ROM? I definitely need to be able to manually select my network, so if's become a non-issue, just need to know what the best way to accomplish it.
Advice\suggestions?
The limitations are built into the modem package.... Not the rom.
Right now the rogers modem performance (and when we say modem, we mean the modem software that tells the radio how to communicate with the network) is on par with the newest att modem with the only difference I can see it the being able to manually select any network.
Bella as for you, unless you rather use odin, to flash with clockworkmod you indeed need the modded 3e recovery and the I9000 version of cwm on your phone...

I installed mod'd 3e Recovery just fine, then flashed the radio posted above in this thread. Seems to have flashed fine, however the manual network selection is STILL greyed out. Any ideas as to why? Seems like another member who said the ROM (Stock AT&T Rooted) is responsible. Are you sure this isn't the case? Any idea as to why I can't manually select a network now?
Thanks!
Now with the Rogers Modem installed, when I go into Network Selection it still is greyed out and says "Default Setup" .. put in a foreign SIM that has both AT&T and T-Mobile USA provisioning allowed, and it doesn't let me select which to use.
:-(
Guess this doesn't resolve the issue. Anyone else have solution as to what I can do to get that Network Selection box available to use? This is the first phone I have ever owned that has disallowed access when I put in a foreign sim. It's getting really annoying dealing with Samsung's inadequacies between flashing and operational limitations, ugh. I would go back to HTC in a heartbeat if the Inspire 4G got better battery life. :-(

I seriously feel you on this one. And if there were good general alternatives on the market from other brands, but this year seems to be in the gutter across the board.

I'm just baffled. How is there not a solution that'll allow me to select the network I attach to? I'm not even an AT&T customer. I paid full price for my handset, it's fully unlocked, doesn't even have the AT&T radio anymore, yet I can't select the carrier in the carrier selection menu? I weep for the future of this country's wireless industry if the ATT\T-MO merger goes through.

Well, its called ATT-exclusive, almost a current flagship of a phone. I'd never buy it the way that you did, but I sincerely hope that you'll be able to iron this whole thing out.

Huh?
a) I'm able to use it just fine, why would you never buy it without contract? That makes no sense.
b) How are you having trouble unlocking it? It's the easiest unlock of any phone ever made. Doesn't get any more simple. Takes 10 seconds.
Hey I was just wondering if it was possible to unlock a Skyrocket then flash a Tmobile radio and receive H+ data speeds. How would I go about doing it? Which radio would you suggest? Thanks.
Nobody? Theretically it could be done but I just want someone to confirm for me.
After unlocking phone someone tried running t-mobile sim and he said only edge but he did not flash t989 radio so idk. If i can unlock it for free i will try it and let you know.

I have an opportunity to get my hands on one of these phones very soon. I have a HTC HD2 on T-mobile's network. If it is not a bother, could you verify this? I wouldn'' want to be responsible for you bricking your phone, but I would be most appreciative for the information on it's possibilty if you know what you are doing.
It is unlocked.
What do you need me to verify?? I m confused !
Because you can run t**** on i727 with edge network plus you can flash t989 radios on i727 i done that before but not with t**** sim card.

its not possible because t-mobile radios for skyrocket dont exist, so you can't flash an other radio for tmobile as it wont work and you migh just end up screwing your phone. tmobile sucks man, change to anything else.......if you like good hardware that it
Yes they exist what you talking about!! YOu can flash them. Here you can dload and flash it through cwm.

HSPA+ will not work with the Skyrocket no matter if a radio exists or not. The simple reason is that supported H+ frequencies are 1700 for download and 2100mhz for upload and skyrocket only goes 1900mhz and 2100mhz. So unless you are able to enable the 1700mhz frequency, 4G or 3G will not work with the skyrocket! Edge is the only frequency that will

Its already been proven that the SR has the 1700/2100 bands, just not enabled in software. Its why we can flash their modems and it works perfectly fine.

I'll be travelling to the states next week and will flash either the Telus or Tmobile radio to use Tmobile's prepaid plans. If no one's replied back to you by then, I'll let you know what I find.
However, there are already reported success of people with SR and the Telus radio using the phone on Canada's 1700 AWS network (Wind).. so pretty sure it'll work. Flashing the radio is safe as well, I've already done it once.
Well make sure you do nandroid before flashing that t989 radio. Plus he wants to know how it will run with tmobile sim card and t989 radio on unlocked phone.

Thanks I appreciate it
OK, I'm in Orlando now and got the T-Mobile prepaid plan...I flashed the T-Mobile vk1 radio and for some reason, I can't connect to any data. I wasn't even able to go into the mobile network settings screen to see the apn settings. Got a msg to insert a sim card to access services...
I then flashed the telus radio and got 3g right away. Speeds are pretty pathetic tho...only 2m down...maybe I'm just too spoiled by lte
Anyways, it's been a long tiring day so I won't do anymore testing right now..maybe tmr I'll try the other kl1 T-Mobile radio.

Thank you sir. This is what I feared-hopefully the other radio serves you better.
So no update on how the radio worked?
I have a Galaxy S II running the UCLE2 ICS Leak, I love the phone but there are many times I'm in a area with a real weak LTE Signal but a great HSPA Signal and times I'm in a 2G Only Area.
I know that the AT&T Modem is Locked so you can't switch off LTE or set it to 2G Only, If I got the Unlock code would that also remove the Rat lock? if not can you use a Rogers Radio on a AT&T Rom?
Thanks
No removing the sim lock will not help i believe the only radio that is unlocked is the rogers KJ7. Not sure what rom your using but some have a selection in the network screen i am using ChimeraVsSkyrocket_Beta2 and it has that option sorry i was trying to get you a screen shot but the usual buttons are not working
So is it safe to flash the rogers radio with me being the AT&T Radio?
If I flash the Rogers Radio with the AT&T APN's Should everything work as normal?
And If I decided to go back to UCLE2 Radio is it you like your basic flash with CWM or would I need to do the Samsung 1 Click to restore the phone to stock?
Thanks so much for your help
Rogers radio will work with att... though signal and speeds will be different. maybe better, maybe worse. its different for everyone.
and it will only work if the rom you are using has the option in it. such as a rogers rom or some other custom roms.
and flashing back to ucle is through cwm. exact same as when you flash the rogers radio...
i'd try the new rogers radio if i were you. it should be RAT unlocked. i get drastically better signal over every other radio (though i am a rogers user).
you may need to switch roms though. if thats the case i'd advise using the chimera rom. since its confirmed to have it. (not very many AT&T roms do.)
The latest rogers modem works with SKY ICS. I flashed it but the signal sucked so I went back to ULALC4(Best for me). Not sure if this is what your looking for but theres an options in your wireless network settings that allows you to use only your 2G networks. Actally has a sub title the suggests it saves battery. Might wanna check it out.
Sorry if this has been posted somewhere else but I did a bunch of searching and couldn't find anything that explained what I'm looking for. Just got the Skyrocket and I'm trying to disable the LTE. 4G is awesome but I'd like to conserve my battery as much as possible and I don't need the super awesome speeds when the phone is just sitting my pocket while I'm at work. I've looked at a few different ROMs, both ICS and JB, and with the stock radio (UCLI3) I can't tick the check box for 'Use 2G Networks Only'. It checks then unchecks and then grays out. I tried a few different radios too, UCLL3, UCLK4, UXLF3, and a radio for Bell for the I757 that I suddenly can't find the info for. All of them work and give me 4G just none of them work with my ROMs to let me use just EDGE.
So far the ROMs I've tried is the new Dirty Unicorn JB ROM, AOKP ICS, and CM9.1 which I believe is also ICS. What am I missing? The last phone I used I didn't have to mess with any radios so this is all new to me. In short, what radio do I need to make this work with the ROMs I've already tried or can I get a recommendation on a ROM/Radio setup that accomplishes this? I'd prefer a ROM that is AOSP since I'm not really a fan of TouchWiz (It just doesn't feel right for some reason).
Did you try going in settings to mobile network click on mobile network mode and change the setting to gsm only? That should give you up to hspa and hspa+ for data speeds. As for using just EDGE I can't help you with that...sorry.

I believe the UXLF3 Radio is RAT Unlocked and that's the one I'm using now with Cyanogenmod 9.1 and I managed to get it to use 2G only. Not sure why it wasn't working with AOKP which is also ICS. I'm not sure if there are any RAT Unlocked radios for Jellybean yet but now that I've got it working I'm afraid to try any other ROMs lol
All this radio stuff is still making cross eyed though. I feel like someone needs to do a really good write up explaining it because it's not easy to wrap your head around if you've never had to mess with it.
Hi
I just bought an unlocked i727 (AT&T Skyrocket). In addition to unlocking it, the previous owner also modded the phone to work on AWS bands (HSDPA 1700/2100). I was all impressed by this feat, but now that I come to XDA, I find all the guy probably really did is flash the radio, which probably both unlocked the phone and enabled AWS (explained here: http://forum.xda-developers.com/showthread.php?t=2029650). Currently in "About phone", the Build Number is IMM76D.UCLF6 and the Baseband version says unknown.
The phone is running stock Android 4.0.4 (ICS), and I want to put on the latest CM10.1 stable build, but when I go to this page, it says I need a Jelly Bean radio: http://www.teamchopsticks.org/p/cm101-release-notes2.html
So now I'm worried that if I choose the wrong radio, I'll no longer have AWS bands, which I need since those are the only bands my carrier (Mobilicity) uses. Can someone please tell me which of the radios listed on the teamchopsticks blog I should use to keep the AWS bands on CM10? I'm guessing its the T-mobile version (UVMC6)...?
Thanks!
Edit: Alternatively, could I just install CM9 and leave the current radio as is? I don't really care if I have the latest android version, I just want to get rid of the stock AT&T rom and its associated bloatware.

You can't unlock the operator lock with a radio. You need both a specific radio and a specific firmware.
AWS support is not a special feature that can be enabled, afaik it's a standard function of this phone.
The Radios made specifically for this phone (Rogers & AT&T) should have full AWS support, I don't know about the others.
Also the TeamChopsticks site is mighty dated.
You should check out the official threads in General and Development.
Also these links are always good to have:

Hmmm... well do you know if its true that CM10 requires a "Jelly Bean Radio"?
Or am I better off just loading CM9? That way I shouldn't have to modify the radio, right?

You could try flashing CM9, then it might even say in what radio you have.
Yes, CM10 requires a Jellybean radio.
If you flash the Rogers radio in my signature or the AT&T radio you'll still have AWS and it won't relock your phone.
There's really no reason not to flash a JB radio and CM10.1.. you're not losing out on anything by doing it.

AWS band in HSDPA (or HSPA+) is not enabled in at&t or Roger's radios,since those 2 networks don't use it for HSDPA.. It's used for LTE (700,1700/2100)
AWS 1700/2100 band in HSDPA can be enabled by flashing T-Mobile blaze JB radio...It should work on cm10.1 since it is a JB radio...
So I spent pretty much all of yesterday reading up on the subject. Since we were under a tornado watch all day anyways, I really had nothing else to do!
After a while, I found the "secret codes" (listed here: http://forum.xda-developers.com/showthread.php?t=1492700), and punched in *#1234#. This told me that my radio was "T769-UVLB7", which I believe is the 4th one from the bottom on this page: http://forum.xda-developers.com/showthread.php?t=1895400, ie the Blaze radio. That would make sense because it gels with my Android version (4.0.4). Anyways, googling that radio eventually led me to this link: http://forum.xda-developers.com/showthread.php?t=1507825 which had a ton of useful information. So thats the radio mystery solved.
From the same info screen, I could see that my ROM was i727-UCLF6, a somewhat outdated stock ICS rom. So now I know what my phone's current status is in case I need to bring it back because my other combinations don't work for some reason.
So I think I've decided to go with the Pacman JB rom (http://forum.xda-developers.com/showthread.php?t=2178402) and if it doesn't work with my current radio, I'll first try the updated Blaze radio, UVMB1, listed third in that same list I linked to above. If that doesn't work, I'll try the others in that list until I get a combination that does (probably starting with UCMC1). I'm also considering the Jedi Mind Trick T989 rom (http://forum.xda-developers.com/showthread.php?t=1818305). I'll post results when I have them!
Thanks for the help everyone!

So what you're saying is: AWS for LTE is enabled in Rogers and AT&T, but, it's disabled for HSPA by default.
I was under the impression that 2100 is used for 3G/HSPA by default eitherway, but you're saying it's not?

Didn't notice any difference after flashing Blaze LB7 radio. Vodafone has 2100 for 3G/HSPA. Already had full signal with RUXUMA7 and it was still full with LB7 and speed was the same (3.7Mbit down/2.6Mbit up)..

I would recommend you do more reading and reading before you mess with the radio flashing
Good luck

AWS (Advanced Wireless Service) protocol uses the 2100 for downlink
and the 1700 for uplink..
http://en.m.wikipedia.org/wiki/Advanced_Wireless_Services
The skyrocket has the 2100 in 3G and LTE
but 1700 is not enabled in 3G
Hence the AWS band (UMTS band 4) is not supported in 3G

Thank you for explaining this, I didn't know all the specifics.
You are correct, the Blaze radio disables LTE and enables AWS.
As you can see here 1700 is not in use in Europe. So the Blaze JB radio is of no use to me.
So in the end, the Pacman JB 4.2.2 ROM worked without a hitch. I did not have to flash the radio at all, it is still working as before.
Baseband still shows up as unknown (the nifty secret codes no longer work), and kernel is now 3.0.72 cyanogenmod.
The phone's working greatI love it when a plan comes together!
What speeds do you get currently on speed test app ?
If your goal is a rom with no bloatware you can debloate a stock tw one...Personally I can never live with cm camera...
At the moment, only about 1.5 MBps, but I am not in a good service area. Even so, everything seems to load quickly.
My only complaints so far would be the ROM itself... already crashed a couple of times, and it has a bizarre way of connecting to the computer (no USB storage mode).

So it turns out that it may noit have been the ROM after all, but GO Launcher. Everytime I get a new phone, I get sucked in by GO Launcher's sexy looks, but the result is always the same: lagginess and crashes. After switching to Apex launcher, things seem to have settled down.
In terms of the radio, I did some more traveling around today and I would have to say that reception is not as good as it is on my AWS Nexus S, so I might try some different radios after all. Just want to confirm though that if I use an i727 radio (like UCMC1) instead of a T989 radio (like the Blaze radio), I will no longer have access to AWS. Is that right?
Right now I'm thinking UVMB1 from here might be the first stop: http://forum.xda-developers.com/showthread.php?t=1895400
If you ask me , TW stock debloated and tweaked by me is my and always be my rom ...
For the reception, if you have to have the best reception for a network that uses AWS 1700/2100mhz bands for HSDPA/HSPA+ , the skyrocket is not your phone...Or you have to live with issues every now and then...
That's why your nexus s(the T version) has better reception it's a device with native 1700/2100 band support...
Try some other T mobile radios from the blaze,Hercules or galaxy note 1 (remeber you have to use jellybean radios with any jeallybean based rom) and see what gives you best reception, but again don't expect miracles...
Or another note, try a stock jb uvmc6 rom (flash a skyrocket kernel for the roation problem) and uvmc6 radio or another T-Mobile radio as a combo if it is better regarding general network performance...
Edit: answering your question,yes ..skyrocket or Roger's modem will not have 1700/2100 AWS HSPA connectivity...And that "first stop" was my first advice for you...UVMB1 radio...

Hey mahanddeem,
Thanks again for the help. Even after removing Go Launcher, I'm still getting a few random reboots/shutdowns per day - enough to annoy me. I did some searching and found out about the sticky button issue, but I have a feeling thats not my problem. Usually when the phone shuts down on its own, I have to remove the battery before the phone will turn on again. I'm not completely discounting the possibility that I have a sticky button, it just seems odd that the solution involves pulling the battery. That makes it seem more like a software/Rom issue to me, so I'm thinking of going back to a TW-based rom, but I don't want to restore my original stock with all its extra bloat-ware. All that to say that I was hoping you could tell me which de-bloated TW Rom you are using. I've found Embryo, which looks interesting: http://forum.xda-developers.com/showthread.php?t=2074328. Is that what you have?

Thanks for the suggestion. I'm trying to avoid a full stock ROM, mostly because of the bloatware and branding (I can't stand seeing a corporate logo every time I start my phone!) - this is basically the reason I put a custom ROM on in the first place - plus the extra control of course. If this is the only thing that will stop my phone from randomly rebooting and shutting down though, then I'll have to consider it. Hopefully the stripped down TW version that you recommend will help though.

Heh heh true enough I still haven't tried flashing anything - I'm still educating myself. The last thing I want to do is start something I can't recover from!

I take it you don't know how to root a stock Rom and delete the bloatware yourself?
Sent from my SAMSUNG-SGH-I727 using Tapatalk 4 Beta
I'm pretty sure I could root it, that much seems within my limited skill set. But first determining HOW to remove the bloatware, and then WHICH things I can safely remove... That I'm not sure of. Besides, if there are already ROM's out there that have done this, why would I duplicate the effort? I'm all in favour of doing things just so I can learn how to do them, but the fact is I have other things I need to do with my time besides fiddling with my phone (family, work, motorbike.... and seemingly endless friggin yardwork!)

It's very simple, there are plenty of ways to remove bloat, plenty of guides to do it, and charts that show what things are and if you should remove them.
Embryo would be a nightmare for you. Read the thread. If you don't have the time to research and learn, you should not be flashing things on your phone.

Do your researches, it's not gonna happen that anyone here would put a long extensive guide for you so you can "take a look" at it during your coffee time...
Everybody here is learning everyday from others' posts, problems and discussions...So either you put some effort into learning or nobody's gonna spoon feed you..
As a clue , look at Mohan deodexed stock UCMC1,flash,root,start freezing apps that you know you'll not use...Then using any root explorer you can permanently uninstall system apps...And by the way you can use a custom boot animation even on stock,search for how to...
