Hi guys i need some help from you guys and developers . As we have 4.3 roms ported to our device by very great developers but we all are facing data loss on these roms. when device screen goes off for few minutes and while making screen on i see no data connection on my device . Problem i came to understand that its a modem issue because 4.2.2 modems are not compatible with 4.3 software . my question is that can we safely flash modems from AT&T SAMSUNG GALAXY S4 OR I9505 devices . All roms and kernels of AT&Tand i9505 devices are compatible with our device. In past on my galaxy s2 T-mobile device i flashed modems from AT&T variant and they were working fine. may be this can resolve our data loss issue
Thanks for your help and advice ....
I believe that this time around the modems can't be flashed from different carriers correct me if I'm wrong

Not without breaking the phone, you are correct.
In past on my galaxy s2 T-mobile device i flashed modems from AT&T and verizon variant and they were working fine. It was the same issue when we upgraded . This was the solution to resolve data connectivity issue . And some developers also modified the modems to resolve the issues on Galaxy s2 to make them compatible .That's why i tried to share my past experience . But now we can not go ahead with this problem until we do not resolve this issue . we do not expect any update from T-mobile for our device in near future . only developers can help us to resolve hardware and software complexities .

Here is the deal, NONE of the custom zip file roms found here in XDA which we flash contain "MODEMS/RADIOS".
There is a good reason behind why they don't have modems. (brick at worst and soft brick at best if we flash modems)
The only firmwares/roms which contain MODEMS are those which we flash using ODIN, like stock roms which
are specifically designed for our M919 Tmobile Galaxy S4 phones and no other models.
These zipfile cwm/twrp flashable tmobile/at&t/i9505 roms for the most part can be interchangeable especially
if we flash a proper kernel for our specific phones but if you flash MODEMS you are just asking for a lot grief.
Good luck! (you just might need it)
I was just asking because it was possible . i was using galaxy note radio on galaxy s2 t-mobile SCH -T989
In this thread you can see galaxy note T879 radio for galaxy s2 and telus radio which was canadian variant and blaze 4g radio for galaxy s2
http://forum.xda-developers.com/showthread.php?t=1895400
I used galaxy note radio on galaxy s2 . i do not claim its my idea but i give credit to those developers who made it possible on galaxy s2 when it was upgraded from gingerbread to ics. i am not like others who steal others roms and claim their own .
I was seeking help from our developers to look into and tell us the possibilities.
T-Mobile devices support different LTE bands than other carriers and the i9505, which means our hardware is different, specifically the modem. Pretty much everything else is the same, which is why we can run other carrier roms. Radio comms are another beast though...not saying it couldn't work, but its much lower level than the OS/ROM is.

Hey, I would normally have started a threat in the proper subforum but it seems new users require 10 posts minimum
Has anyone with this rom encountered issues. everytime I reboot the phone, I end up having to wipe it which is somewhat annoying as you can imagine.
Also, yes i am a bit of a noob but i had successfully flashed my galaxy tab 2 10.1 with nowhere near as many problems as i am having with the s4.
note that this is a canadian model and that the baseband is I337MVLUAMG1. I see now that it stated I should be using the ATT baseband.
how do i go about flashing that?
i guess im alone in canada...
Hey everyone,
I'm definitley not a noob at flashing roms / rooting / unlocking , etc....Been flashing phones like crazy the last few years (s3,note2,htc one,nexus,etc)But I have one question that I cannot find the answer anywere.. I bought a T Mobile S4 which was blacklisted on T Mobile so I am using it on AT&T wtih full LTE.. Which Roms do I flash for this thing? Do I flash TMO roms or ATT roms, or does the kernal flash just matter? If this is a stupid question, sorrry! lol. Just don't want to brick this thing.
Thanks Guys.

Not trying to sound TOO condesending, but you haven't read much of anything in these forums if you couldn't find your answer to that. All variants of the S4 can flash each other's ROMs as long as you immediately flash a kernel for your specific device. You have a T-Mobile device so you will need kernels from this section; but you are free to use ROMs for the AT&T, Sprint, i9505, etc. Just don't flash anything via Odin that's not meant for your specific device, and don't flash anything at all meant for the Exynos version (i9500).

Yeah I know most ROMS support all Variants but I wasn't 100% sure. I must of been searching the wrong things....I was confused with the kernal flashing as well. I have always owned a Carrier Specific device and never have used an unlocked device thus far, so I was a bit confused . Thanks for Clarifying though! :good:
Infamous S4 ROM has an Aroma installer that will support multi carriers.
Look at the change log for more details.

How are you still using the blacklisted phone if it's blocked for tmobile? Thought the two carriers shared imeis?

I was going to say the same thing. If you're blacklisted on T-Mobile, you'll be blacklisted on AT&T. I have a blacklisted T-Mobile and any sim (even international) is blacklisted while in the US. However, in other countries, it works fine.
Hi,
Ive looked into flashing an AT&T rom on my Canadian n7105 LTE Note 2. I searched the forum and some people said they have flashed it no problem. Other roms only say for n7100 only...
I am positive on my old note2 i flashed an AT&T rom. Ended up dropping and breaking the phone so i bought a new one. I don't require to have LTE but i do need 3G data connection.
Can i Flash a MI6 ROM like Hurricane Rom on this thread:
http://forum.xda-developers.com/showthread.php?t=2467910
Thanks
That rom is for the n7100 if you flash it you will lose phone and data and be left with just a tablet. Afaik there are no stock based 4.3 roms for the n7105. Some of the American roms work on the n7105, there is a list somewhere

Is there such thing as a T-Mobile Samsung Galaxy S4 rom? My S4, I was debloating it and messed it up so my cousin helped me flash it with a different version of the S4 TouchWiz rom but I'm having problems with it (freezing, restarting, shut down). So here's to you hoping someone can help us with this.

See if sammobile.com has the stock firmware and if it does flash it in Odin
The SHG-M919 is the handset sold by T-mobile, by T-mobile. Under settings>more>about device the baseband version for T-mobile should be M919UVUAMDL. If this is the case, that you have a T-mobile handset.The back cover should also say T-mobile, unless it's been replaced.
That is a ATT baseband.. Interesting!
Well if you are brave flash T-Mobile stock and let us know how it goes!

Can you flash s6 edge Roms on s6 what will not work if it will work at all. Also T-Mobile Roms. Do they work on sprint? Possibly just a radio and kernel flash to get them working?
Bump. I'm currently on 920V (Verizon) where roms are interchangeable. Does anyone know if 920P follows the same suit?
Edit: Found my answer. For anyone who still has this question. They are interchangeable as long as you flash unikernel afterwards. However since 920P & 925P are compatible, it doesn't mean you can flash other roms (outside of Sprint) without the dev's verification. So keep checking OPs!
I installed 2 different tmobile roms to my g920p sprint thats gsm unlocked . But baseband is unknown and imei also. Have you had any luck getting a gsm rom on these cdma devices?
