Hello,
This is a newbie question. Is it possible to convert Cricket Samsung Galaxy S4 SCH-R970C to a TMobile version of S4. I know Cricket uses CDMA and Tmobile uses GSM but someone told me that S4 is the same device and only software is different between carriers. Can someone let me know if this is even possible?
thanks

The guy at cricket told me they use a different type sim card so I don't know if it's possible

I believe it is safe to assume you may add t-mobile elements software wise but the radios are different the cricket version is CDMA and T-mobile runs off of GSM which is completely different technology, so compatibility is a no go its litterally two different devices at that point, may be able to flash to sprint or verizon that works with cdma but even that im not too sure with
Hope that helps

why don't you just decompile a Tmobile ROM and just take the system.img.ext4 and recompile it? I did that to a USCC stock ROM and flashed it over to my Sprint L720 and it works perfectly.

no bueno homie
you cannot use the T-mo version on CKT, or vice-versa
This is an old thread I know,.
Is there anymore information on this? I have read it can be done.
From cricket to t-mobile galaxy s4
cricket galaxy s4 schr970c
I would love to take this phone to a different carrier. I realize that the cdma is an issue but there had to be another carrier that I can switch to. Does any one know how I can switch carriers using this same phone?
Yeah, i have the same question as this. Would i risk bricking my phone if i tried loading a tmobile rom and modem to my cricket phone?
Bumping this older thread cuz I see no resolution and I have a similar question...
In my research I found this thread: http://forum.xda-developers.com/showthread.php?t=2409392
-The OP flashed an i9505 rom onto his R970C cricket GS4, but apparently he found it doesn't alter the modem/radio firmware, and THAT is what is different in our Cricket phones.
However, I personally am looking NOT to use this phone on a GSM network (T-mobile)..but on a CDMA (ideally Page Plus/VZW)..for that it would seem the radio is the same! -And actually I found this quote on a different forum (cricket user one):
"Cricket Galaxy S4(SCH-r970c) uses MDM9615M RF chip which includes GSM functionality which is the same chip found on Verizon Galaxy S4(SCH-i545)
Anyone try flashing a VZW firmware and also VZW modem firmware? -risk to brick it I'm sure..but, then again..maybe it just works!

Where can I find modems. For sch-r970c the old ones.

Aloha brother!
I haven't done that in a long time. If you are interested in it, let me know. It's a little bit more complicated to do especially with the bringing of Samsung Knox but I feel I can try my best to help. If you still need my help, reply to this and I'll offer as much help as I can. Making far balls is easy; but getting them to be applied with correct settings is a pain the the you know what.

R970c in others networks

I recently got an S5 from Cricket/AIO. Was wondering if it was the same as the AT&T version because I wanted to root and put a custom ROM onto it.

Most of us have no direct experience with Cricket because it's not a natiomal carrier. It's only an option for a limited number of US zip codes.
Looking at the specs, starting with the model number - SM-G900AZKZAIO strongly suggest that it's just a rebranded ATT 900A model. And sure enough the specs say that your phone uses all of the same frequency bands.
So the overwhelming chances are that it's ATT compatible in all significant aspects.

Just picked one of these up on Black Friday. Care to share your experience with custom roms for this model? Did the Roms/root for the Att variant work okay? Thanks in advance!

I would be very interested to know as well and thank you for starting this thread. Looking at the settings I see the USB TETHERING and WIFI TETHERING is completely missing from the settings altogether. Thats one main reason I want to root so I can actually use my data outside of the phone. Plus the boot animation is Cricket branded. So its not just a relabeled AT&T phone. The model number also ends in 900AZ not 900A like the AT&T version. The kernel is NE7 thought.
I also found this thread:
http://forum.xda-developers.com/galaxy-s5/help/flashing-sm-g900az-galaxy-s5-cricket-t2863858
Lets move on to that thread.
Hello, I have a Galaxy S5 from cricket. Samsung-SM-G900AZ with a 5.0 Android Version. Can someone help me root it?
I've successfully rooted and installed the unified blisspop from here on my 900az. It was a long time ago. I think I had to use odin...
---------- Post added at 12:46 AM ---------- Previous post was at 12:45 AM ----------
Get all the perks of ATT coverage but with an unlocked bootloader.
Was looking at the unified rom section to see if it's worth to go ahead and root my phone as I've held off. Got really lost quickly with all these abbreviations. kltexx,kltelra,kltetmo,kltecan,klteatt,klteub,klte acg,kltedcm,klte. So many. I know mine is kltetmo as I have a TMO S5. Does that limit my rom choices to ONLY kltetmo or would i be able to flash a klte build? I know i wouldn't want to flash a klteatt and such but what about just klte?
thanks!
the same as that question. How can everyone help me?
How can i distinguish kltexx,kltelra,kltetmo,kltecan,klteatt,klteub,klte acg,kltedcm,klte?????
You can use klte ROMs on your T-mobile which is international LTE (900F) since both are GSM.
Can anyone help me with my model s5(SM-G900R7) are there any roms out that I can flash I'm kinda new to this
Ok so I am trying to change my unlocked T-Mobile Samsung Galaxy S5 into the AT&T version. I don't want a customer ROM. I have unlocked the T-Mobile phone with T-Mobile. Now I want to use it with ATT. yes I know I can just drop the SIM card in but this is not for me, and I need it to look just like the ATT version. This is so I can give it to my mother -in-law, not for any devious purposes but because it is the easier way to go for her to handle it.
The T-Mobile phone has 4.4.2 on it. It is unmolested. Just stock. I have looked over some forums and some post but not really seen the step by step guide. I have downloaded the Stock firmware of the phone for ATT but when I used Odin to try and flash it, it fails. I am guessing I need root access or something like that. Can anyone confirm this? Can anyone tell me how to do this?
Thank you!
So does no one know how to do this? am I asking the impossible? it cannot be that hard? Anyone point me in the right direction?
Hi all -
I posted this question on CM forums - they suggest I also try here - I have a Cricket Galaxy S4 - post AT&T buyout. It is a GSM/LTE phone using CM11 and a Cricket SIM card. I was wondering if I am limited to CM11, or if I wanted to upgrade to CM13, would I just use the current jlfteatt builds? Anyone out there in a similar situation?
Thanks!

What's the exact phone model?
Since it already has CM11 you should also be able to get CM13 on it.
Both the "about phone" and sticker behind the battery say SGH-I337. Sorry for being noobish about it, but is that what you are referring to? I know the S4s cell in different flavors, but otherwise I just think it is the garden variety S4. I guess my main concern is all the talk about the basebsnd versions. Mine doesn't match exactly, but not sure if that is just about rooting the phone. I am of the same mindset that it should work if I have 11, but I can't afford to brick my phone just from a time perspective (never mind money as well ) but I want the shiny upgrade sooooo badly....?
Thanks!

There's nothing you can do about the basebands and bootloader. If you update them your device might get locked and no custom roms or root can flashed anymore.
Sincthe the phone already has CM11 I assume it isn't locked. So just flash a newer recovery (TWRP) and flash CM13.
