[R&D] Porting G925F or any (version) Roms to Sprint.

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.

Thanks. I noticed that some roms here http://bbs.gfan.com/forum.php?mod=forumdisplay&fid=1619&filter=typeid&typeid=12037 claim to support the G925P sprint. I haven't tested yet but plan to. They could possibly have everything working.

How To flash N920P with international firmware version?

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

seeking for the same solutioN!

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.

Hey insane howd you get 4g? On att?and are there any good roms for sprint note 5 with att

You should just flash a rom with custom recovery. odin to hit or miss for me unless I'm going complete stock

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.

930U on other US variants, but what about on F?

So I've seen that it's possible to flash the US firmware between the carrier firmware and US international firmware (U). I'm wondering how that is possible since there were problems with the S6 international variants flashing US carrier firmware onto the phones. Does the U use the Snapdragon processor and that's what allows it to be flashed?
The reason I ask is because I know someone with the S6 international (G920I) on T-mobile and wishes to enable WiFi Calling but they don't have that option. I know that this isn't the S6 forum but I noticed people flashing U firmware onto their carrier branded phones and vise versa and figured that those who figured it out would have some understanding as to how it works. I just want to expand my knowledge of why he can't seem to find a solution even though there seems to be some compatibility there.
Thanks for the replies.

Well, it could be possible.. But since this is the forum for the international version of the s7, I think you might have better luck asking that same at the US s7 forums.

G955FXXU1AQH3 unlocked, bloatware grabage problem.

Hey fella's, and ladies. I just got my G955F, bought inside of the US off of the same person I usually go through. Turns out It's a UK model that came with Vodafone bloatware and shows 4G instead of LTE (even though it IS LTE). Is there a US variant? And if so can I flash the phone with any G955F variant software using odin? So I guess I'm asking, what is the best, and purest firmware if I am in the US. I have T-Mobile and I'm in Cali. Thanks ahead. (Sorry, but I posted this in the S8 section originally, like a dumb-dumb)
Also, could I flash with G955U unlocked firmware?

http://updato.com/firmware-archive-select-model?exact=1&q=SM-G955F
Here you can download the US ROM and use Odin to flash - these are official ROM's so Knox will not be tripped

NO
You CANNOT flash a G955U rom to a G955F device
It will definately soft brick or even hard brick your device
You can flash this rom ( https://www.sammobile.com/firmwares/galaxy-s8/SM-G955F/EUR/download/G955FXXU1AQH3/184528/ )
No bloatware, multilang and fast updates.

DON'T GIVE WRONG INFORMATION!!!
If you don't know what you talking about, then say nothing!
You CAN'T flash G955U FW to a G955F
Do you know the difference between the G955U & G955F?
If you did, than you would have known the answer!!!

Got it. Couldn't find any US firmware on that page. Part of my question about the US firmware, or multilang firmware comes from the fact that Walmart sells G955F's. I would imagine whatever firmware is on there would be what I would want. Just don't know what that is.
-Thanks for all the replies so far. If I can't figure out what firmware comes on the US Walmart G955F phone, I suppose I will go with the variant listed above.
-Also, will VoLTE work on the multilang rom? Or is there a rom that works with T-Mobile and VoLTE? And if anyone is wondering, I wanted to Exynos variant, that's why I didn't buy G955U.

Hi guys, I've just got a G955F as an upgrade from Vodafone UK with lots of their bloatware. Can I flash any other firmware over it without tripping Knox or invalidating the warranty? I'm in the UK btw.

Flashing My Note 20 Ultra 5g N9860(BRI) with SM-N986U1 firmware

Hi,
I was wondering if its possible to flash US unlocked firmware onto the unlocked dual sim Taiwanese variant of the Note 20 Ultra 5G (SM-N9860).
There are certain features like Samsung pay that is somewhat limited for me because its still shows the region as Taiwan.
Of course I don't want to brick my phone but wanted to see my options in terms of changing the region to a US version.
Also, just to confirm, there is no way for this 5G variant to get 5G with US carriers, correct?
Thanks

SAme question here.. can anyone help please? also can anyone help in this issue:
I am living in UK, have note 20 ultra 986U1. all 5g Bands are not active, on android 11 (UI3.1) there was a way to access to service menu and enable all 5bands. and I was using the 5G here. now, I updated, and that can not reach seavice menu to enable right 5G band. anyone has any idea what should I do? even I can not flash with UK rom, as UK rom is for Exynos, but mine is snapdragon. any other idea maybe? or other rom that works with my phone and also enabled 5G bands?
do you think if I just change the CSC , my problem will solve? if yes, which CSC I must flash and how?
