I know the Samsung- Fascinate, Mesmerize and showcase are all very similar that is why I am also posting here. My phone build and specs are updated in my signature. I know where to go for rooting it and I know the deal with flashing.
I also know that EC01 was a radio update but mine is EC04? Maybe it's a local thing from my carrier?
I do have a couple questions about carrier settings and such.
I am on a CDMA EvDo.rev.A network and I know my carrier partners with Verizon down south.
What problems might I run into when flashing other ROM's:
Will flashing a ROM mess with anything my carrier needs to keep me connected to the network? If so what?
Will i be able to flash a ROM from either of the three forums for the three phones listed above?
Thank you!
I have to use the backup and restore APN app to keep data with GCI
Okay so I'm currently running an ATT rom and radio combo. I want to first fully understand the difference between the two. I'm really unsure as to what the difference is and which one is better for what?
My next question is that if I am to switch from ATT to Rogers, do I just simply flash the new Radio and thats it? I've heard elsewhere that u must dial #*2.....something something and mess with the APN settings once u flash a rogers radio. What are the exact steps?
Also is it true that in order to get the capabilities to turn OFF LTE, I MUST switch to Rogers because it is "RAT Unlocked"?
Im having terrible service because I am in an LTE test site and I really want to turn it off and save myself the headaches from constant loss of data and reception.
I apologize for any repeated questions; I'm just trying to learn. I've attached my current build.
Thanks in advanced for any help.
I think yes roms are interchange but not all radios...and yes Rogers radio is RAT unlocked so you can disable LTE...which you can't do with att radios

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 Everyone,
I am about to get an I727 (Galaxy S2 Skyrocket) online. I want to give it to my wife so she can have a reliable phone.
After getting it network unlocked, can I use it with T-Mobile, especially WiFi Calling (I guess I need Stock T-Mobile rom?)
I just want to make sure T-Mobile's Galaxy S2 is identical to AT&T's I727 Skyrocket, and network compatible.
Thanks in advance to those who care to reply.
I did a little bit of searching both here and online (after finally getting the model numbers of T-Mobile and AT&T) the result is they work, but data will not work with each other's networks. So unless I want to use them as 2G devices, and spend a good deal of time trying to root them, 727 won't fully work on T-Mobile network.
Flash a T-Mobile radio. Read this sticky thread.

Rooting is easy. Read the sticky threads and you'll have no problems. Just make sure you read the sticky's fully.

I have a rooted and unlocked at&t skyrocket on jellybean 4.1.2 with very slow speeds, so I tried flashing the radios UCMC1 and UXUMA7 through cwm and nothing has changed. After messing with the APN settings a little my data is no longer working. It shows the bars but I can't get a connection. I have broken my back googling and searching forums on this matter but I can't seem to figure this out.
I just flashed the radio UVLI1 in the hopes that I wouldn't have to post this but now my bars are gone and have been replaced with a slashed circle. Any help please?
Edit: I flashed back to UCMC1 with the bars showing but still no data. Also, I just realized this should be in the Q&A but don't know how to delete the thread so I could post there instead.
1st , Welcome to xda
2nd , it is good that you're aware that it's the wrong place to ask , it should be in the Q and A section here :
http://forum.xda-developers.com/forumdisplay.php?f=1401
3rd , you have to know what T-Mobile is using in your area ,
If LTE is rolled out , UCMC1 should work perfectly fine , since stock Skyrocket radios use 1700/2100 AWS bands for LTE (use this apn : fast.t-mobile.com)
If not , try one of the those radios :
Blaze 4G
Hercules T989
Or Galaxy Note T-Mobile (not so sure about this one) ...
Use this apn : epc.t-mobile.com
Search for those radio zips and make sure they are Jelly Bean compatible radio , or else they will not work with stock Skyrocket JB rom ... Always be careful when messing with radio , it can corrupt your device IMEI and/or brick it , make sure the radio you use is safe when used with Skyrocket..
Hope that helps...
And by the way , there are tons of infos on the stikies you should look at here

Thanks for the suggested radios. And apologies for that double post in the Q&A, I thought this thread would be locked/deleted because of the sticky in this section.
I figured out that changing the APN type was what caused me to lose the edge data, because I had changed it from default,supl,mms to internet + mms since I had seen that in another thread. Changing it back restored the edge.
By the way, I had obtained the aforementioned radios from here.

I tried flashing the Bell I757 from this thread http://forum.xda-developers.com/showthread.php?t=2312596 but again no change in speed. I also tried flashing the UVMB1 Blaze radio from http://goo.im/devs/Void_Dweller/T769-UVMB1_modem.zip and I'm still on edge. Am I missing something here? Thanks again.
Set a new APN as :
Name : T-Mobile
APN : epc.t-mobile.com
Leave everything else and hit menu, save.
Select this APN
And you didn't answer about what service T-Mobile is providing in your area... If UCMC1,I757MUGMC3 or blaze radios didn't get you to at least 3G speeds then you have a problem somewhere else...

I did as you said with the APN but it seems l do not get any connection at all despite the bars being present, so I have to have the APN type at the bottom as default,supl,mms for the data to work.
I checked T-Mobile's website and it looks like I'm in the area with 2G with some spotty "satisfactory" signal strength areas. I would think that even with 2G that I'd get more than 0.04 Mbps download and 0.03 Mbps upload according to the speedtest app. Is there nothing I can do?
Asking somebody who's using T-Mobile in your area (a neighbor or a colleague) is better than just relying on the T-Mobile coverage map... And if you're sure that your area only gets 2G , use the stock JB UCMC1 radio and live happily with the 0.04 mb down you're getting... I would look to another carrier in such a case...

Ok, my only concern is that when I do change to another carrier in the future, would I experience slower data or data problems since I've already flashed a different radio? Would I have to flash back to the original one? I'm looking at this radio here for the original: http://forum.xda-developers.com/showthread.php?p=20157930
Thanks.
Man that's very basic stuff of course you can always flash whatever you want, including radios...
Having the skyrocket you're ofcourse limited to the 2 gsm networks in the states, T-Mobile or att (and their mvno's like Straighttalk, red pocket or such)... If T-Mobile is not good around you ,you have no choice other than at&t and in such a case flash the latest stock radio at that moment.. Now it's the ucmc1.. Use this link

[RADIO][UCMC1] For I727/I727R [09-APR-2013]
You're lucky not to be flamed for those basic questions, but be careful next time, there are really awful members around here who have no basic attitude or respect what so ever....
OP, i noticed that going into the carrier settings and manually choosing at&t instead of automatic has fixed this for me using a t-mobile straight talk connection....see if it works for you
I am using the at&t skyrocket on tmobile as well and find the samsung note modem to work the best leaving the apn settings alone.

Also make sure you check data roaming.
