Missing network type setting? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

It seems on everybody elses phones in the settings under mobile networks they have a "2g only" setting. Mine just doesnt have it, why? Anyway i can get it back or force 2g/3g because I dont even live close to a 4g or LTE area and only have 3g and the fact LTE is on searching for a connection is wasting my battery.

Att skyrocket does not have this feature......but pleanty of custom roms do.

Any that will work on stock kernel? And will it trip the counter or whatever? I've never flashed a rom before.

Are you rooted? Flashing roms through CWM doesn't trip the counter.

Installed rogers Rom on my i897 have you?

so I just installed the Stock rogers Rom on My i897 and will be running some gps tests. so far all the normal stuff works, locked on 10 satellites in about 20 seconds after deleting gps data. was able to root with CL's superoneclick without too much trouble. anyone else with similar experience. Maybe we can compare Jupiter files?
where did u get the rom i wanna try it.

This should be the Rogers 2.1 modem file if you want to give it a try.

Yes mobile AP and sideloading work by default. I just checked mobile ap and works fine.
okay. that's good... i have downloaded rom posted above... any other precautions? 3button mode working after reflashing rogers firmware?
Does the Rogers Captivate have HSUPA??
NO it doesn't
only galaxy s AFAIK support HSUPA are with european modem, but with it you can't call (if you place eu modem in us phone)
"okay. that's good... i have downloaded rom posted above... any other precautions? 3button mode working after reflashing rogers firmware"
Make sure you back up your EFS folder. just as a precaution. this stores information about your product code and emei unlock code ect. this is very difficult to recreate.

There is an issue with the 850 band using an HSUPA modem.bin, but there's a wor-around for that. It doesn't prevent you from making calls.
apparently is does, noone can't hear you and you can't hear anyone...
thats odd, I just made a call on mine and it worked fine.

Installing CM9 on skyrocket will allow to choose 2G/3G network?

I have brought an unlocked version skyrocket from at&t. Since I stay in India, we don't have a 4G and it's shame to say not even full 3G coverage here as of yet.
My question is when I move into 3G coverage area I see 4G instead of 3G and I feel battery drains quite fast during data usage under 3G (or 4G for phone). So I heard in Roger version of skyrocket and some custom roms allow switching off 4G completely ( 4G/LTE/HSPA+). So does cyanogenmod 9 allow such feature to disable 4G connectivity which is not there on at&t rom? Anybody who has already flashed CM9 on at&t skyrocket can reply so I can root this device and go for CM9 or other stable that allows such feature.
Thanks.

Where in India..? How did u manage to get carrier signals... I struggled a lot to get the signals, I had to flash stock ics uclf6.. may b d radio in it was the thing did it...
Into the topic,.. yes u can switch 2g/3g... you don't need to root ur phone... u can flash a recovèry using Odin.. then flash the custom rom... u get root if the rom is pre rooted... if not u can flash su... I'm using sky ics now but I'm unable to switch network mode.. people say it might b radio prob..
Pls post back if u succeed with cm9..
Thank u..

Yes, CM9 allows it. I'm on TeamChopsticks' CM9 and the option to switch is available in the Wireless and Networks setting.
However, do understand that you need a RAT unlocked radio. That's actually what allows you to switch to 2G on the skyrocket -- having a RAT unlocked radio. You can find a list of radios in this thread.
Hi!
That's what I was about to say: if I understood correctly what I read, having a ROM that allows you to choose between network modes (LTE/HSPA/GSM) is not sufficient. Your radio should also be unlocked -- like Rogers' radio. Changing the settings in your ROM when you use a locked radio -- like AT&T's radio -- would have no effect.
I've tried using this feature in CM9 and it doesn't seem to work. It was noted on their list of problems but I don't know if it was ever resolved. I have an unlocked RAT and I still can't get it to work right. Somewhat annoying because during the day I'd like to have it to save battery, but basically I gave up on trying to get it to work.

Sorry that doesn't seem to work. That may only work in Touchwiz based OSes, but in CM9 it's not doing anything.
Reported this belongs in q&a or the developers thread itself not in the general section.

So does it work in Sky-ICS? Im on AT&T so if I am going to install the rom for the first time what radio would I use?
Yes, I have rooted my new skyrocket with cwm touch recovery and flashed CM9 Stable version and it seems to working perfectly for me. .
Let me know if you face any problem and if you are from India. Will try to help if I could :beer:

I know it works on my ROM (EMBRYO) always had this feature since I travel to India it works perfect. You need to be SIM unlocked and a RAT unlocked RADIO (like any Rogers RADIO NOT ATT)..

You mean I need to unlock my phone in order to get this to work? I didn't have to fully unlock my Nexus 1 to do it. Is it different with the Skyrocket?
No you have to use a rogers radio rat unlocked isn't the same as unlocking the phone

Huh? I guess I must have worded it differently. You need to be SIM Unlocked AND have a RAT Unlocked radio, to change the preferred network mode (at least on I727)...sigh..

odin to rogers stock flash rogers stock ics modem first. Then root and install cm9.
If that doesn;t work try the same process just use rogers gb

I tried doing the ODIN with the Rogers ROM and it kept failing. I had to then install a custom recovery and then flash CM9.1 and it still didn't work. Before trying this I tried another ROM (Embryo) to see if that could toggle and it couldn't either. :crying:

Hey Omario. Did you're other rom says 4g? I was a little dissapointed to find out that doesn't mean jack cause att lies about 4g. It really isn't lte.

Hit the coverage button to make sure you have it in your area?
If you do? Maybe try the lte switch app in the playstore, and mess with the APN a little more.

@grim yes I always do clean wipes
@suburadroid(or however u spell it) I know that they lie I actually enjoy seeing my signal up....but even with this I have every thing set... It just acts like I have no mobile network anymore I had to call att and have them activate lte last time this happened but that was right when I got the phone
Update : I guess for twenty mins my phone wanted to act up than start being normal again..... Thanks for the responses though!

Sprint LTE

I have a new N5 and its unlocked and rooted. I get LTE just fine on the stock rom but when I flash any custom roms, LTE doesn't work. Even when I restore my backed up EFS on the custom rom, LTE still doesn't work. Anytime I nandroid back to my stock rom, LTE works fine. Any ideas or help will be appreciated.

Did you flash Sprint software? It could be the APN.
What sprint software? forgive me im new to this. I did make a backup of my apn of my stock rom and restored it when i flashed a custom rom, but it didn't make a difference.

I think there's some extra APKs you need to add to custom ROMs.
I fixed the issue. I unrooted and returned my phone back to stock. Then I found a sprint. Zip that you flash with custom roms and that worked.

Its a zip to flash after roms that sets the correct APN settings for sprint. I can't remember the thread I found it in though. But it was for the same issue I was having with my LTE/3g switching.

The reason I am searching through posts is this: my 3G works fine. But when it kicks over to LTE... Nothing happens... In a minute or two I may get 4 mbs or something pretty good and then nothing again. I need it to actually work. My wife has the same issue on her S4 and she is stock. It switches over to LTE.... Nothing. I have LTE off mostly. Steady slow 3g is better than no progress on LTE.
update profile
Should provide the correct settings in the custom Roms assuming the creator added the update profile features. I know cm does

I have the LG G3 on a custom Rom for Tmobile. I'm switching over to At&t tomorrow and taking the phone with me. Can I just install a stock based rom over my tmobile stock rom or do I need to follow a method. Please and thank you for any support or point in the right direction.
Its Rooted with TWRP installed already.

Yeah the rim does not affect the carrier. Why where you running a D851 rom on a D850? Wifi calling?
Sent from my iPhone using Tapatalk
You dont really need to do anything as TM and ATT use the same LTE bands and share IMEI databsae info. I had a TM note3 that I used on ATT until I got a G3. The ATT sim will register you on the network and you'll want to make sure you have the correct APN settings ( The ATT store can do it while your there or can tell you what's needed) The only issue I had was the TM modem didn't always get great signal and wouldn't place calls in some areas. Not sure of G3 but ATT modem wouldn't flash on my note 3 via odin or otherwise... Cheers!
