So I am looking to get a smartphone. Never really had one, and I am looking to get an android phone. In the end, I think from what I have researched, to get a SR, on the TMobile prepaid network (I am not a fan of contracts and paying too much for what I need. I would mainly need data, and the TMo prepaid seems to work out the best). So I want to make sure I got all the steps covered.
So from what I gathered, in order to get a SR on TMo, I will have to root it, unlock it, then install a TMo radio to get TMo's 3/4g network.
So the steps I need to take are:
Make a backup of the stock phone (or find the Stock Rom) just in case anything goes wrong? I think this is called Nandroid backup? I am not sure how to make a backup myself though? I believe I can just Clockwork Recovery?
Root the phone (is the root permament? Or do I need to do it everytime I restore the backup/stock ROM?)
Install Custom ROM (I am probably going to either install CyanogenMod or Sky ICS).
I found instructions on CM here: http://wiki[.]cyanogenmod[.]com/wiki/Samsung_Galaxy_S_II_(AT%26T):_Full_Update_Guide
For Sky ICS, I was going to use: http://www[.]traemcneely[.]com/2011/12/27/install-custom-rom-at-ciq-removed-short-review-instructions/
Unlock phone. Is this temporary? Do I need to get a new unlock code everytime I change ROMs, etc?
Install Modem ... I do not quite understand how to do this. I found a list of radios that is supposed to work in the i727: http://forum.xda-developers.com/showthread.php?t=1426001 I think I get the SR Series Rogers KJ7 modem. But I am not sure how to flash the radio only?
Am I missing any steps? I want to be sure I got everything I need to do this. I haven't bought the phone yet, but I am researching everything before I get the phone.
Alot of the information I got from: http://forum.xda-developers.com/showthread.php?t=1383464 I was going to Root it by zergRush.
Also, I was wondering if I should wait for the new SoC chip from Samsung to be released? I read that the Exynos 4212 will be released in new phones soon (rumored to be in the SGS2+ in next week's Mobile World Congress) and that the new Exynos chip will support LTE? Where as now, the SGS2 SR LTE is the qualcomm chip.
And the reason I was thinking LTE was that if I didn't like TMo and its 3g/4g network, I could then try out AT&T and their LTE network. I am in LV where they have the LTE and TMo's 4g network.
But anyways, if I am missing a step or doing it in the wrong order, any help would be appreciated!
Wow, I'm impressed. I wish all noobs did this much research before flashing a phone, instead if doing it wrong, bricking it, and the. asking why lol. Your plan will work, u can flash the tmobile radio in cwm, same as u did the rom, skyics is fine, and u only have to unlock phone once. Little tip though, once u flash and root and all that jazz, in wireless settings set mobile networks to gsm/hsdpa only, no lte. This will help battery
You will need CWM before you can make nandroid backup and flashing roms.

Guide will help with rooting or flashing custom rom right away (which should be rooted already).
Radio is also flashed through cwm just like custom rom.
Hi all,
I hope you can help me with the following:
Recently I bought an unlocked galaxy express i437 (the phone is originally from AT&T) and I am able to use it with other carriers with no problems but there is no way to change the technology (there is no "network mode" menu). Searching around, I found that it can be changed manually with code *#2263# and going through the sub-menus which is a pain to do.
I was thinking in rooting this phone and install CM10.2 in hopes of getting the network mode available directly from the settings screen but before I try that I need to know if the phone will remain SIM-unlock as it currently is or if there is a risk of having it bound to AT&T after the rooting process.
Thanks in advance.

hey guys new to the site....i was hoping somebody could help me... i have been trying to flash my phone at a cell phone shop but they were not able to do it. The owner tells me my phone is not remembering the flash when it boots back up...He has also tried rooting my s4 and it is still doing the same thing. They tell me it might be a motherboard issue. what do you guys think
Hello Xda, I am new to posting, but I am legit stuck on this and i require help so hopefully I can here. I own a US Cellular Galaxy S4 sch-r970 running stock (flashed stock) 4.3 flashed to Ntelos using CDMA workshop. Its not running 3g (damn 1x) but i hope to soon resolve that with prls updates. But before i can do this i need to find a way to root with ruining the flash (basically no flash rooting with odin or custom boot menu :'(... ). I have already tried framaroot (they don't support 4.3 with aragorn or gandalf....) and i wanna try kingo but they won't give me a straight answer of weather or not their application is compatible with flashed phones. So to put it simply i wanna root my phone and if there is no way not to ruin the flash can i keep root and reflash??? plus if anybody can help me with the prls because my phone everytime 1x is turned on/off the phone calls *228 and i know i need to update the prls.... sooooo yea if anybody can please help i would appriciate it very much. Thanks.
G'day everyone,
I have installed a few custom roms as I have found out that I can't get 4G (LTE) at all as the preferred network.
However when I go back to stock I can get 4G on my phone.
I have spoken to a friend of mine who is on the same network running one of custom roms I tried and has 4G (LTE)
Was hoping someone might be able to help me
Btw I don't have battery saver on either
Cheers!
I have also tried to update the radio to 4.4.4 and also tried 4.4.2 just to see if anything happens however I still unable to get 4G unless I'm on stock.
This has me baffled and still hope someone might be able to help me
Did you download the latest and correct APN for LTE?
Hi,
I recently brought over my SM-G920A from ATT to T-mobile. I cannot get the ATT phone to recognize the existence of the Signal Booster--which works great on T-Moble phones--so I cannot connect to it. I have been a few rounds with others here that have walked me through the attempt to flash this phone with T-Mobile baseband load and it simply will not work. The phone is unlocked and is using the following load:
baseband G920AUCS7ERC1
BUILD NRD90M G920AUCS7ERC1
I have dev mode unlocked and have no idea what to set those settings at or what they were originally, I attempted to flash SM-GO-G920T onto it but it will not take because there is no current bootloader that can overwrite the ATT version.
So, I'm about to go back and flash the old software back on here.
But, I would really like to see if anyone has any ideas that can help me either get this phone to recognize the T-Mobile 4G-LTE signal booster or help me figure out how to get this phone to accept the SM-G920A load all together.
I would like to thank everyone in advance for your time. Please help.
Thanks and have a great day!
