i9508 is the China Mobile model of Galaxy S4, which supports GSM and TD-SCDMA.
A group of people made a custom ROM to enable WCDMA on i9508.
Seems i9508's got both WCDMA and TD-SCDMA support, and WCDMA is disabled by firmware.
However, people also report that they see "i9505" on those i9508 they buy. So, maybe i9508 is just a software-modified i9505 on which WCDMA and LTE is disabled.
So, anyone knows if i9505 also has both WCDMA and TD-SCDMA on it?
P.S.

Yes, I9508 = I9505 + custom firmware
As far as I know, Snapdragon 600 supports WCDMA/TD-SCDMA/LTE, and someone said it can be hacked via *#1111#

What I am looking forward to is unlocking TD-SCDMA on the coming Galaxy S4 with Stock Android.
And it's also DUOS!

100% sure this will be possible?
My next phone needs to be TD-SCDMA enabled, have all gapps (so not a chinese version) and hopefully stock Android.

I have, and I can't find an answer to my question on the page, it just says;
There’s another Chinese model, the I9508, which is a single-SIM Galaxy S4 with a Snapdragon 600 chipset. This one is China specific and differs from the I9505 in its TD-SCDMA support (the 3G tech in China).

Will it be possible to enable TD-SCDMA on any i9505, and specifically on the the stock android S4?

Some people tried to raise money to buy 2 i9505s for the development. However, it doesn't seem promising. Only a few people donated, so the total amount will hardly reach the target. On the other hand, ROM makers already built ROMs for i9508 which enables the phone to use WCDMA instead of TD-SCDMA.
So there is no proof that an i9505 could support TD with some software level hack, even though the two models share the same hardware (or almost the same, i don't know).
So, for now, the only choice for TD seems to be i9508. I believe the CM-based ROMs for i9508 are coming soon (maybe they already built one).
They did.
Guys, I have a GT-I9508 and flashed into custom rom via Touchwiz UI and everything works very well. Once I used to have some wifi and bluetooth issues but I solved it with latest official rom.
Here is what I've done:
1) I flashed the GT-I9508's software with the latest official rom. (This updates the baseband of the device which means wifi and bluetooth connection issues are gone)
2) I flashed Omega v42.1 Android 5.0.1 Based on firmware XXUHOF2 ( which you can find it here: http://forum.xda-developers.com/showthread.php?t=2253528 )
Now, I have GT-I9505's rom runs on GT-I9508 without any restrictions even Google Products.
Regards.

I'm assuming yes, since it's all the same hardware but I just want to make sure prior to posting something from this section, or should I just stick to the T-Mobile forum variant (I have a 900T)? I was able to flash things on the T-Mo HTC One just fine from the international versions, is this the same?
I'm still curious because i want to try the X note rom on my US tmobile phone, anyone know?
Ok well to answer my own question the ROM does work, the only thing that does NOT work is the WiFi which I'm assuming is just a kernel issue. Any help would be great. thanks
I am trying to find solid answers on this before I do it, but can't find any evidence it will work, and without issue. I just want to gain my T-Mobile wifi calling, and be able to use IPv6, but the ROM that my Note 3 came with, does not allow any of this (APN protocol is perma-greyed out and of course no wifi calling).
So here's what I have: Mexican N900W8
The ROM I want to flash: N900T for T-Mobile. Stock ROM.
Can I just simply use Odin and just flash it without rooting or anything since both are stock ROMs? Or do I still need to root it?
Also, if it will just flash right over, will my phone identify itself as a N900T and get over the air updates for T-Mobile, or will it ID itself as a N900W8 still, and possibly have future update problems?
Lastly, will all the other hardware work fine without issue? Wifi (most important obviously), NFC, etc?
Thanks.
I tried looking for this kind of cross flash but could not find anything whatsoever concrete that re-assures me this will work.
I would really like an answer for this.
Can I cross flash a stock ROM or not, and in this case N900T to N900W8 without any wifi issues?

You can flash 900T ROMS on the W8, however, not via Odin. Has to be done via Custom Recovery and you still have to flash the W8 kernel for it to work. - Essentially yes, You have to root, but I don't think you can get your T-Mobile WiFi calling unless you have an actual N900T.

As radical said, you can flash it using custom recovery.
It will show up as N900T instead of N900W8, but you can change this using "build prop editor" from the Play Store.
You will not get any OTA from T-mobile, custom ROMs don't get official OTAs.
I went and got a N900T then from T-Mobile. Have a N900W8 for sale now.
Will the i9505 stuff work on the SPH-L720T? It's the branded Sprint version of the i9505 and I don't want to brick the damn thing. If there is anything I need to know, now would be a good time to tell me. I will point out that I have the 4G version (I think that's the only version made for this model anyway) and it is unlocked to work on all networks. Will I loose that if I flash a custom ROM?
Secondly, I am looking for a ROM that is as close to the stock experience as possible but doesn't have all the issues of stock! But with fixed stagefright issues, the widget draw on Touchwiz UI, and better power saving features.
Thirdly, recovery: what is the best one to use? I was thinking TWRP since I already have experience with that. Do I also need to match up an Odin version for my device?
I think that's about it for now. Thank's for the help!
If the code was jfltexx, it's safe to flash. Just check the ROM's thread for any special guides if available.
For stock-based, no idea. I don't have an I9505.

Thanks. Where do I find the code to tell?
On any I9505 development thread with jfltexx on their supported device list.

It's a rebranded I9505. They have identical hardware.
Your phone has a tri-band something. I don't know what it does, but it seems to be carrier related. That's the only difference between the normal SPH-L720, I9505 and your model.
There seems to be a problem that is common to all marshmallow ROMs, on N900T and possibly also
other versions: once GPS locks, it immediately unlocks again, to lock again, unlock again, and so on.
(I find it easiest to see with the app GPS test - but flashing can be seen on other programs, too)
I've seen it described on Phronesis 6.0.1 (see, for example post 4869), Darklord N7 port (in this thread they seem to be using the app GPS location tracker, which seems to solve the problem, but use battery).
So, my questions are:
Does anyone have GPS working correctly on marshmallow with N900T?
Does this problem occur with any other Note 3 version?
What are possible causes of the problem? Kernel? Modem? How to debug it?
Maybe the problem is with modem version? I have OL1.
I'll try to collect info into this post...
Possible solutions:
This solution on darklord's N7 modifies etc/gps.conf.
This post reports good results with the app GOS location tracker.
This post from AryaMod reports good results with custom gps.conf. Though this post says that the app GPS test still has lock problems.
This post claims the problem is solved by adding "CAPABILITIES=0x11" and hashing out ON_DEMAND.
I tried the CAPABILITIES=0x11 solution on "TouchWiz Marshmallow for Note 3 (V4)", and Arya, and still got flashing GPS lock.
I tried the new "Darklord with all fixes, gps fixed", and GPS still has a problem.

I think this is not a problem specific to N900T, which is why I'm asking here to try to see what devices have the problem... On the various marshmallow ROM threads I don't have the impression that it is a problem just for N900T.
But I have one.
I understand. I have a Note 3 running a stock ROM so I can't offer any possible solutions. Good luck in your search.
Maybe the problem is with the Modem version? N900T has a fairly old modem, whereas N9005 have newer versions. Maybe those that have newer versions installed have no problem, but older ones do, or vice versa? Please report what modem version you have...
I am on n900w8 and I have the same problem. I've tried n900t roms n9005 roms ive tried changing the firmware on my note to a older and newer canadian version. I noticed this problem starting on 6.0.1 never noticed it elsewhere. Its a real bumer.

Im using n9005 on phronesis 6.0.1 n7 port v4.1. Tested on latest modem with lsskernel 3.5ux and 3.8 ux with no hit... only get gps location but cant navigate as no glonass satellite fix... anyone has same issue?
Modem should not be a problem as GPS is on kernel .
Modem or wiFi does give A_GPS .
if you read the forums you will see many models saying GPS does not work on MM .
Fixes are many and varied .
Problem appears to be the simple fact that its a port .
Me N9005 custom rom various and never had a GPS problem .
