thanks.. will try

well, I tried it and I tried flashing the stock radio as well, but nothing worked. earlier today I was getting aldi almost everywhere and now I'm not

I thought changing that setting doesn't work for our phones? If it did we wouldn't need an lte toggle.

Have you Tryed removing all apns except the lte one?
I flashed a Rom and had the same issue flashed to a new Rom based off stock and that was the only apn listed and voila it worked so I wonder if that is why?

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.

Try using this code *#*#197328640#*#*

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

That's what I figured but I have an unlocked RAT (I727RUXLF3) on AT&T and I still can't get it to switch to 2G on CM 9.1..

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..

Ok I am now SIM unlocked and Rat Unlocked and it STILL won't toggle over. Any Ideas?

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
the att modem does strange things with network selection. It works for me when I dont use automatic network selection

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:

that's not for sim or carrier unlocking, that's for bootloader
if you use a different rom like cm10 you can use sim, or maybe in stock you can still use a different sim aswell
iv used a att sim and it works, did you switch your phone to GSM or GLOBAL mode

are you running stock TouchWiz or something else

I believe you need to be on one of the JellyBean leaks to enable GSM or Global mode.

I Didn't. Change. The Mod how. Can I do it.? What leak would you recommended? thank you. For reply

what Rom or leak is a good one. Please help
Thank you

Leak #4 was just released, but there are lots of custom ROMs built on it. It is your personal decision what you want to run on your phone.
http://forum.xda-developers.com/forumdisplay.php?f=1672
Read up in this forum if you are looking for ROMs. If you don't know what your doing, read the guides at the top and start learning.

i would suggest http://forum.xda-developers.com/showthread.php?t=1832070 CleanROM v5, its not up to the latest leak i beleve but it keeps the touchwiz feel and you really loses no functionality. and yes it has gsm and global mode. i can confirm that because i time to time use a at&t sim card

Stupid question, but is VZW's SGS3 carrier locked requiring an unlock code from VZW? Or if the phone is running a global ready ROM, can I simply put in another (GSM) carrier's SIM card?
Thanks!

[Q] Rogers/Fido software help

Sorry if somebody's covered this but I am on Rogers Canada and ordered a razr hd lte, but it shipped with Fido software. I had an old koodo phone that I reflashed once and it booted up with Telus software, and did not work on the network, but after finding a hidden code for it I was able to select Koodo, and it rebooted with Koodo software and worked fine. I was wondering if this phone has an option like that and if anybody knows what it is. I was assuming there might be because the rogers/fido software seems to be the same.
Thanks for any help

Mine was a Rogers phone but as soon as I stuck my fido Sim in it switched to Rogers

Factory reset the phone then reboot. When you're setting it up you should then get the popup to setup the phone based on your SIM

LTE on custom Roms?

Hey guys,
I recently rooted my phone and installed paranoid android 4.0 beta onto it. Everything works properly but I can't get LTE reception at all. I have tried forcing the phone to only connect to LTE through using *#*#4636#*#* and all I am getting is no service|rogers. I have tried this on other Roms(omnirom) but to no avail. Can someone explain why I am not getting LTE reception in an area I should be getting it?
Much thanks ?
BTW if it helps I live Toronto and I'm with Rogers

Most likely it is your APN settings if LTE was working on stock and you have not flashed a new radio. Unfortunately, Rogers' site has not been updated with correct APN settings for devices past 4.2 : http://www.rogers.com/web/support/wireless/android-customize/1363?setLanguage=en
Those MIGHT work, but somethings can change between updates and being in the US, I've no way to help check. I believe the main issue is the APN has to have this: ltemobile.apn
Found this for the N4, which I am assuming the APNs will be similar, if not the same: http://www.thegadgetmasters.com/2012/11/23/how-to-nexus-4-has-lte-how-to-enable-4g-lte-on-nexus-4/
Good luck.

Yup the APN was the issue thanks!
