Hello (I have nothing)
This is to discuss Sprint porting with data/ Introducing myself/ A few questions
Please don't reject this (my) project. I will reject my project if I find out it's impossible or absolutely not worth it.. Please also don't tell me to just do it, I would need more research time.
Of course this would be great. Any request for Sprint support posted in other models Rom sections get rejected quickly. But it's been done. Not with this phone, but anyway...
About me:
I had built an AOSP Rom for A Virgin Mobile HTC Desire 816.. And coded A few Apps, so I know A bit around the Android system. Different hardware, I know. With that phone I could just flash A universal APN fix that fixed mobile network when using any rom for any world model. There are close to 20 or more variants. I'd like to create A flashable fix like this. Virgin Mobile uses the Sprint Network.
I have A github (same username), and A fast ((can use over 500GB RAM!)) Microsoft Azure remote server (Ubuntu Server, Windows, free for me) which I use for development which I may be able to "donate" access to for A few people.
I'm new to Knox systems
A few questions:
It's really that secure?!?! I can't even directly "sudo" in A rooted Linux install on the S6 edge. I've been searching the internet everyday for A Samsung Pay workaround/alternative use for the magstripe. But I highly doubt Samsung will open an SDK/API for the Magstripe.
This is possible right, simple porting procedure? Though I've been unsucessful with porting since Lollipop.
You can flash and boot apparently any rom for an S6 using A sprint kernel as well. Just it doesn't know what the SIM card is.
I would like to link porting resourses such as [Guides] from the Galaxy S5, S4 for reference.
For now I will check on gsmarena.com for the supported bands and whether they are GSM/CDMA of the different models.
Anyone working on this, knows what to change, or has more resources than incompatible guides please let me know. If there's any enthusiasts on this subject.
Not much is happening with the S6 not even with AOSP teams. I see that all the news was the way to go and NOT root it because people want Samsung Pay.
I've actually tried flashing a G925F rom. It booted etc. But it showed baseband unknown so I changed some system files etc. but it still shows baseband unknown. All other things were working perfectly.
There isn't a whole lot involved in porting for the s6. But From what I understand, the issue with porting to sprint is with how many files sprint has places carrier specific files into. I was planning to do a port from sprint to other carriers for Dazed and I after full oh1 builds are completed.

Actually the real problem is reading sprint period with the s6..will not read anything sprint whatsoever
Modem, data, efs, iccid anything. Ive been porting roms for sometime. Not happening here

I had taken advice from A site which I was sure would work, but didn't.
Backup partitions efs, modem, carrier, everything that seemed to be storing "carrier stuff" to restore IMEI. Then restored the partitions in the G925F ROM. Using TWRP and the Partitions Backup app by wanam.
Interesting that when flashing Sprint ROMs that are based on A previous build/baseband version, the latest OH1 baseband version shows within those roms.
When using global s6 roms, baseband version shows whatever that rom is for.
Any files in the system noticable that are required to replace? Then change where the port rom looks.
Also the sprint basebands are in OTA's. I'll check those out by comparing update tars. Maybe they're found more easily.
But when flashing G9250 roms (Hong Kong/China) basebands shows and it works fine except making calls (can't talk or hear the person).

did LTE work?
I live in europe so the sprint s6 bands are not supported but I think it will support 4g/lte in the usa.

You were saying the Europe S6 is similar to the China version?
I had starting looking for Hong Kong Roms to flash to my Sprint one. Lol.
A quick search showed that the European model is the G295F, or at least similar. No?
Apparently no bands are the same accept us cdma carriers https://en.m.wikipedia.org/wiki/List_of_LTE_networks
No, I mean the sprint g925p is similair to the g9250 from china. If you flash a g9250 rom it'll find the baseband etc. And no the g925f is not similair to the g925p nor the g9250.
Why doesn't' someone contact a developer like @AntaresOne or @Alucard24. @AntaresOne is the maintainer for International CM 12.1 on the Galaxy S4. He is also the developer of the Optimized CM 12.1 builds. The optimized builds run on any carrier variant of the S4. One ROM, all variants! @Alucard24 is the kernel developer for same. They would both have tremendous knowledge into carrier independence.
I know AOSP, but should be useful.
I had gotten no futher on this.
The steps I had taken were moving any Sprint CSC files into other roms, as well as following porting guides dealing with gsm->cdma porting, and the other way of moving system apps/files from other roms into Renegade ending up with force closes or not booting.
Also A popular kernel for those Roms, Arter kernel had become less and less likely to work. It booted with no data at first, now it doesn't boot.
Sorry that was just A lot of file picking and I'm not good with xml and everything else.

Hi, guys
I've been looking for any major differences between the SM-G920I vs SM-G920F. I'm aware there are some differences regarding the frequency bands but appart from that I don't think there are things to set them appart - is that right?
For instance, would it be possible to flash a 920F rom into a 920I withouth issues? If there is a difference is the bands, perhaps the Modem would underperform in comparison to its actual original rom.
Thanks in advance

I too feel the sane but is there anyone who has tried so?
Sent from my SM-G920I using XDA Free mobile app
ive very much been wondering the same thing as ive been wanting to put the alliance rom and framework onto my Galaxy S6 920I but ive only seen support for the 920F model so ive held off from trying it.
Ever bothered to ask the ROM chef? They know the differences in the stock ROMs simply because one has certain files that the other may or may not have. The more active developers here often have separate threads for those having issues with their ROM, and for bug submissions. Drop by the AllianceROM thread with your questions, but please do some reading and don't post unless you can't find an answer for what you're asking...
Since the galaxy s6 edge has the exynos 7420 cpu does that mean international roms will work on US carriers? just have to change the APNs?

I have been wondering the same thing. Have you gotten any further with this?
I'm in South America and would like to flash an INT ROM hoping to get LTE working here. LTE Band where I am right now is 1900 mhz. Would flashing an INT ROM "unlock" the phone for that? Are there other "consequences" that one should be aware of when flashing an official International ROM? Any comment on this is appreciated :good:

no i haven't found any information on it sadly :/
Im searching information about too. I tried install some 925F roms then flash 925p kernels but no luck. GPS not working, data/voice not working, even no mobile operator setting in setup.
You would need more than just download and flash!!! You need to port libs, xmls, framework, apps etc to make it compatible with Sprint
Anyway of getting a sprint compatability zip?

Thanks for the info. In my case I don't need to make it compatible with Sprint since I'm in South America. Any suggestions on how to flash an official International G925 Rom?
I think that will happens only when somebody write unified kernel for F/I/*/*/*/and P version of this phone. I researched this and found that noone from kernel makers want not do this. In nearby thread one programmer offer to try modified bootloader for 925p (to be able rollback to 5.0.2). He can't even find testers(. No one want brick their phones.

S6 G920F roms on S6 G920P?
Dear users
I would like to have S6 International roms on my S6 Sprint but I can't,
is there a compatibility for sprint file to fix the other touch screen and other processor (exynos and snapdragon)?
Please, can anyone reply if you know it?
PS: Sorry for my English, it's not good.
I'm trying to flash Sprints N920P with any international unbranded firmware. phone is rooted, TWRP already installed and OEM unlocked.
Tried to flash N920CXXU1AOI3_N920COXE1AOI3_SER with odin but failed.
could you please give me any advise? There should be a solution because its hardware is same for every region or carrier.
best regards,
Zaza

Not sure why you would want to do this. If you can get the phone unlocked then whats the point?

Hmm not sure about the theme store but you don't need to use an international rom. You can use a Sprint rom. Although all Note 5's are essentially the same (there might be some variants with differences), the kernel might be different for each. I would stick with the Sprint rom. Maybe try some of the roms posted in the development section to see if the theme store would work on those roms.

nope. i have flashed "sprint" custom rom!
Thing about sprint is...it has its own network. So unlocking it is not the same as tmobile and other networks. Example 1, sprint unlocked only works on sprinit network and other networks by sprint. Example 2, any other company, tmobile, verizion, unlocked can work with a different sim card, internationally. If you put a different sim card in the sprint phone it wont work for some reason, but any nonesprint phone it does if unlocked
This is not true. The N920P can be unlocked and used on domestic GSM carriers. I'm currently using the N920P on straight talk (ATT) with LTE on stock/rooted rom.

How you did it?
I used idoneapps for the unlock (works great, kudos to those guys) .You will have to make NV changes for LTE (directions are on this site). You also need two APN's (one with LTE as bearer). Network Mode needs to be GSM/WCDMA/LTE. Handcent with manual APN for MMS keeps from having to reboot nearly everytime you receive an MMS as well.

NV edits can be found http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455 . You do not need the storage patch for this device, obviously.
I'm about to pull the trigger on buying the S7 and (thanks to this forum) have researched the (T-mobile) "carrier" version with SnapDragon processor vs. the International non-carrier version with Exynos processor. Seems like the latter is generally preferred, with 2 drawbacks:
1) Not compatible with T-Mobile's wifi calling;
2) No VOLTE
My only remaining questions are:
1) It seems as though with most unlocked / non-carrier smartphone models, custom ROMs are usually made available that enable carrier-specific features, but it seems like no such ROMs have yet been developed and widely circulated to enable T-Mobile's wifi calling or VOLTE. Is it typically just a matter of WHEN, rather than IF, such ROMs usually get into circulation? IOW, even though I'll be without those features on the Exynos S7 for now, can I buy the phone with confidence that in the not too distant future there SHOULD be a ROM to enable these? (Wifi calling is actually rather important to me since my gf's apt is a dead zone.)
2) Can someone ELI5 VOLTE to me? I'm still note entirely sure what it is / does, and want to evaluate how much I should care if my Exynos S7 doesn't support this...
Exynos does support volte. I am using it and it works fine.

It works now. I do super man rom. Search that thread how to do it. You have to flash zto csc then boot then flash TMB csc. Then Switch a couple toggles.
I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I have done this and I lost WIFI calling and VOLTE. I'm very happy with it so far.

I just did this today went from TMB locked one to unlocked (For a family member) mine is unlocked. All went well no problems at all. Just download the U1 Firmware you want to flash and for CSC use home_csc (In ODin) so you can keep your data and probably the wifi calling feature too ( i did that all features are intact). Use the Odin and firmware from Ota and non Ota thread . Enjoy

What did you gain that made it worth it for you? Also, I'm on a Locked ATT/Firstnet Ultra and am wondering if flashing to an Unlocked Firmware would give me more control of my device.

If your on FirstNet I recommend that you stay on ATT branded software, I'm not sure if band 14 will work properly for you if you are on unlocked software. Thank you for your service!

You can get VoLTE back, but yeah, WiFi calling is not gonna happen.

The thread is for T-Mobile, but most of it works with AT&T devices as well.

I flashed the U1 firmware (ATJ3) onto my AT&T Note Ultra, then flashed the Home CSC from the AT&T U firmware. I have VoLTE and WiFi calling.
Help!
Hello all, I have a Note 20 Ultra 5g that is unlocked and I'm looking to flash the original ATT firmware for this device.
Having this unlocked version on Firstnet has been nothing but problems and I don't have access to band 14 or wifi calling.
I see this thread is a little old but if anyone could help me out or send me in the right direction I would greatly appreciate it!
I have rooted some of my older phones several several years ago so I think I could pick this back up pretty quickly. I know over the years things seem to get easier and have probably changed quite a bit since I've last done something like this.
Thanks in advance!

My comment was made before we were able to change IMS settings directly.
You can get it all now. VoLTE, WiFI Calling, RCS, Video calling...

AT&T hasn't released any "official" firmware for the Note 20 series.
Since Samsung firmware is multi CSC, just flash any firmware with the same build number as the AT&T variant and use your AT&T SIM card.
Go to this thread https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/
Make sure you know what device you have, U or U1. Then grab the appropriate version.
Fir AT&T U devices, N986USQU2DUCA or N986USQU2DUCA will work.
For AT&T U1 devices, N986U1UEU2DUCB is the most recent version.
