Samsung Galaxy S2 HD LTE SGH-I757M Root and Modem Flashing? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hello everyone,
My friend (who isn't very experienced with android) wants me to root his Bell Galaxy S2 HD LTE SGH-I757M. The only thread I found about this phone is this: http://forum.xda-developers.com/showthread.php?t=1740188 . My main question though is, Can this phone be converted to work with T-mobile network frequencies like the Skyrocket? I'm assuming that the modems from the T989 and the I727 will work on the SGH-I757M? Any input is greatly appreciated.
thanks

Any one know anything about this phone?

I'm actually looking for these same answers. If i find anything out I will post an update and I hope you will return the favor.

Just searched "i757m" and found this thread at the top of the results.. easy as pie...

that doesnt have anything to do with unlocking the aws bands....

Well, it's just a start as the OP has linked other useful threads in his signature and in post#3. I guess you can PM the OP and/or post in the Q/A section as it seems all i727M discussions are posted on the i9100 board.

I found information on changing the modem, as for unlocking all I had to resort to purchasing an an unlock code.
PM me if you need help rooting and changing modem or anything like that.

Changing Modem on i757m to work with wind mobile or t-mobile
Hello,
Wondering if you can help guide/instruct me on how to change/install a t-mobile modem on my i757m.
Would like to make it work on Wind Mobile or Mobilicity. I did some research and found that t-mobile's samsung note 879's modem can be flashed on my i757m. I tried flashing that modem in ODIN but keep getting fail.
Would you be able to assist me?
Thanks.

Zips aren't flashed in Odin. You flash them in recovery. Do some more reading before you brick your phone

Samsung i757m
Hello and thanks for your reply.
I'm fairly new to Android, switched over from blackberry couple months ago.
Do I have to root the phone before flashing the radio/modem or just flash the zip file in recovery mode through SD card?
Also my i757M is on gingerbread right now, would it make a difference if I flash the modem from t879 from t-mobile?
Please, any help would be appreciated.
Thanks again.

I'd learn how to use odin and then find the ics rom for your device and flash it. Then worry about the modem.

Ok Great. I did upgrade to ICS over the air update. Now how do I change the modem on this device and put the t-mobile t879 modem on this.

You have twrp or cwm on your phone? Download the modem zip file to your phone. Then flash it with twrp or cwm. You can wipe the caches first if you want but not necessary

Hi brelliebrown
Here's a tutorial on rooting with cwm recovery and here's one stockbased custom rom and here's CM10.
Good Luck :good:

You would just wipe cache and dalvik cache and flash the radio in cwm. You can flash the radio twice to make sure it sticks.

[Q] Extracting radio/modem from GB2.3.5

Hello, my wife and I both have SGH-I727 (ATT)..they are both unlocked. I use ATT she uses Straight Talk wireless. I have GB 2.3.5 (UCKJ2), she has ICS.
The radio/modem/gps on ICS sucks. In GB is just fantastic. I want to extract the radio from my device, then either CWM apply it from a zip file to her or via ODIN.
How can I do this?
I did find the ATT UCKJ2 modem/radio which on some forum which I was able to apply to her phone via CWM, but the code was apparently locked to ATT and therefore Straight Talk Wireless did not work.
I would therefore like to try to extract it from my phone and apply it to hers.
I have searched and searched but have not found a way to do this. Any help will be greatly appreciated.
THanks!
Have you checked if the apn is the same for the phone that works and the one that doesn't? You may have to manually input the apn.

jd...thanks for the reply...after I flashed the UCKJ2 ATT radio from a thread I found here, I did not check the APN settings. Maybe I did not make it very clear but my ATT SGH-I727 (GB 2.3.5) was not used at all to flashed the Straight Talk (ST) one (ICS). That is what I am trying to do. However,
if you are saying that flashing a new radio may change the target phone APN settings, understood. I can try to flash again (I restored everything back from a CWM backup I had taken before the flashing) and then check the APN settings after the flash to make sure they are still there and correct.
thanks!

I wasn't very clear either. Flash the radio you want to try but then make sure the apn matches the carrier you want to be on.

Hi jd,..I checked the APN settings after flashing the UCKJ2 radio on found on XDA and as I suspected when I hit APN, it told me NO SIM INSERTED error message. That tells me that the radio I flashed was indeed locked to AT&T. So, again here is what I am trying to do
Device 1 Device 2
SGH-I727 Unlocked SGH-I727 Unlocked
Rooted Rooted
CWM Installed CWM Installed
Carrier ATT Carrier Straight Talk Wireless
GB 2.3.5 UCKJ2 ICS 4.0.4 UCLF6

I want to extract just the radio/modem from Device 1, put it on a zip file and flash it onto device #2.
How can I do that?

I may be wrong, but I don't believe any of the radios are locked to att. It's the phone that is locked. If you got a no sim error it was probably a bad radio flash. If you look for vincoms one stop sticky in the development forum you'll find links to all sorts of radios.

[Q] How to update baseband/radio/modem

Hi everyone,
My verizon galaxy s3 right now has a baseband of I535VRLHE.
First I was wondering which baseband is most recent, I have heard of MB1, MF1, etc. I know where to get these software updates but I have not found out how to actually update the baseband. Right now, I am jumping between many roms but as of this moment I am on an unofficial cm 10.1 build. They suggest getting on MF1 modem, but I really have no idea how do it.
Thanks for the help,
PS: I looked for quite a while so please don't tell me to keep looking or something like that.

Do I need to wipe anything for flashing it? Also, its ok to flash baseband updates with a custom rom installed?
And these will make my radios stronger, and thus my signal stronger?\

theres really no answer to pt3
What modem do you guys suggest flashing to. Right now I am on I535VRLHE and by my understanding that is extremely outdated. So just to make sure again no wiping anything, no formatting, no anything? And I should be flashing an update in either twrp or cwm? I know these questions sound stupid when I said I flash roms daily, but I really do not want to risk bricking my beloved s3 hahaha.
Thanks for taking your time to help me.
from what i understand the modem that works best for you will depend mostly on location. they might get better as they update, but i get teh same signal on the latest as I did on a modem from a few updates ago.
you can download the all in one packages here
http://rootzwiki.com/topic/34053-firmware-vrbmf1-modemrpmtzsbl-verizon-sgs3-sch-i535/
reboot into recovery, then flash, reboot back to the ROM. if youre worried, make a backup. things can always go wrong i guess.
Ok thank you again, another question haha sorry. http://forum.xda-developers.com/showthread.php?t=1788313&page=6 In this thread, the first few pages say to flash via odin and what not none of them confirm being able to flash through recovery. Have you ever flashed a radio through recovery?
Also what advantages does an AIO have compared to just the modem.

Go to sammobile.com. You will need to register to download but you can go to top left, check your firmware version. You may need to know what your original csc was but that should be just a request away.
Download the file it gives and flash with ODIN.
This should fix your problem but then again, no promises...

I have a similar request. I bought my US Cellular Note used and it already had CM 10.2 installed. I would like to return it to stock, but when i went to Sammobile.com and registered, it did not list our US Cellular Note's firmware. I was told by other users that there was no way to return to stock on our Note's. I was able to locate a Stock rom for the Verizon version of the Note (SCH-i925) and was wondering if it would work on our's (SCH-i925u)?
Any help is appreciated!
