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.

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..

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:

Here are cwm zips for the radios we have available at this time(that work). These will work for both the AT&T Skyrocket and the Rogers Skyrocket, take your pick I will be updating this thread as new radios become available. Please do not ask for the Japanese SC03DDCMKK3 radio, it does not work properly with our device.
Included in these zips:
mdm.bin
amss.bin
RIL
How To Flash:
Install with clockworkmod like you would any other zip.
I have tested these myself, as well as others on IRC and they have worked fine. I am not responsible if something goes wrong for you.

Thanks for doing this!!! I ended up going out after work so didn't get to it like I planned. If you don't mind I'll just link to this thread but you'll probably be stick-ied too. TA.

After much testing, the current selection of radios seem to offer no difference in performance, the major difference is that the Rogers radio is RAT unrestricted vs. RAT restricted AT&T radio, which allows you to type "*#2263#" in the dialer and set the phone to 2g only, 3g only, 4g only, etc.

FIXED IT! Apparently taking out my SIM card and putting it back in fixed it.
I'm running KK1 and can dd a partition if that's what you need. PM me or message me on irondust(lart).
Hey, noob question but whats the point of flashing this radio lol? Does this actually allow you to use the radio that the skyrocket was supposed to come with but doesnt have an app for?
These are the firmware that control the Cellular Radio, DSP (Digital Signal Processor) and various bootloaders, not the FM radio that may or may not be part of our bluetooth chipset
BTW, AT&T 2.3.6 KK1 radio coming up shortly courtesy of lart, I'm just packaging it up now
Thanks for the fast apply, I appreciate it =) I wish we could get the radio to work on the phone if it really is built in
Did anyone take close up photos of our motherboard yet?
There are various FM radio drivers contained in the kernel, but all of them are disabled @ stock config. No idea if the chip is actually present or not, or if it is, if it's physically wired to the headphone jack (FM radio uses headphone cord as antenna generally speaking)
Close up pics of the motherboard would tell us if it's there or not
I just tried out the rogers radio (I am on ATT) and I was getting extremely low data speeds on EDGE, UMTS, and HSPA+ (10kBps) (tried both phone and PTA apns). Making calls worked fine though.
Flashed the radio and am playing around with the bands using 2263, looks like I can force EDGE by selecting GSM (I assume we should select the 850/1900 for AT&T) and can force hspa by selecting the WCDMA)
How would I force it into 3G only mode, (UMTS?)
Sorry if this has been asked before but how do i access network mode? i believe i used *#3367* or something like that in GB. but i have aokp milestone 6 atm and that dont work anymore... maybe he number is wrong?
I want to set LTE only or maybe LTE/3G only and no 2G/Edge.

Good day people
Im a newb when it comes to radios...
i have rooted / unlocked and installed the cyanogen superlite JB Rom
which i love
Now i'm in canada and traveling to the states in about 2 weeks and i have a prepaid sim cad but its not activated
i have traveled to the states before and used the t-mobile pay by the day plan but could never get any better than 2g connectivity because i have the stock rogers radio...
after doing some reading i have learned that i need to flash another radio... i have flashed different roms etc so i know i can do it...
but im unsure of a few things.
is there a radio that is universal? which will give me 4g / lte on rogers and t-mobile so i dont have to flash when i get off the plane?
if not what are some radios that will work with JB and give me 4G connectivity with T-mobile?
also what radio would i want to revert back to stock rogers / att radio?
i know everyone one says try different ones but im in a different country so i would like to have everything ready to go as soon as i land...
Thanks
Rom...
I am not sure about that specific Rom, but I know with the Official Team Chopsticks version - they list UVLE1 as the radio.
I know that some Roms have modified radios/kernels so check with the Rom Dev for which one he recommends as he knows what he has baked into the rom...
If you are really scared about it, download several and have them handy on your SD card and when you get here you can simple try several and see if one yields better connection speeds for you.
As far as reverting for ATT/Rogers I believe UCLI3 is the latest but might not be the best for your area... UCLF6 was our previous radio and I get good results with both..
Just make sure you make a GOOD nandroid backup and try them all....
Good luck!
tmo uses a different frequency than rogers/att, so the tmo compatible radio has to be flashed, to my knowledge noone modified a rogers/att radio to work with tmo's 3g 4g, im not sure they have lte, theres a few threads on which tmo radio works well with the skyrocket, and remember to add the tmo's apn. need ics radios to work with jb roms. read the links below

I am also in Canada, have had great luck using the T-Mobile card, but unfortunately not with getting my speed up. I did try downloading several different radios and flashing them while in the US.
Unfortunately it went from 2g data to no data or reception whatsoever. So I restored to my nandroid backup and continued on with 2g.
Just wondered though, did you say ics radios are compatible with jellybean? I've been wanting to make the jump to jellybean on Rogers, but wasn't sure if I'd lose my Lte speeds. Any help would be appreciated, thanks.

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

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!
