I just got my s4 yesterday and rooted via cf auto root. It's a 720t with nc6. Is it okay to flash nea roms or do I need to install a nea modem then flash a nea rom? I'm sure I'll lose spark but I'm okay with that.
[Sprint Samsung Galaxy S 4 General] daniel4653:
you haven't read, I can tell. read and search through this thread and then come back to your question if it has not been answered.
[Sprint Samsung Galaxy S 4 General] td030981:
I thought the roms come with modems. Lol!
[Sprint Samsung Galaxy S 4 General] scottypeterson:
From what I understand, I can't install roms that were made for a 720 because then it's possible I wouldn't have spark or could possibly brick my phone. I realize most roms are not compatible with the 720t because they are built for the 720 but I haven't found a thread showing if nea is for the 720 or 720t or what other firmware versions were made for the 720t or if I can use the nc6 modem that Is stock on my phone and install a nea based rom and it not brick my phone. Sorry I really have been reading and the answer might be right in front of me and if there's a specific thread you recommend me reading then I would take that advise too. Thanks
[Sprint Samsung Galaxy S 4 General] td030981:
Some L720 roms work. I had installed a rom ....... can't remember the name of it. Started with the letter V. But yeah it was made for L720. All the roms we are installing are. There are no roms for the L720T. But I did a odin back to stock NFA and took all the updates and I was on nc6. My play store wasn't working so I nandroid back to NFA 4.4.2. Say all that to say look at how my phone is setup now. Don't know how or why it did that but all works fine.

Build number and modem are two different builds
[Sprint Samsung Galaxy S 4 General] frukyyy:
You cannot use 720 modems for 720T, period. Spark is LTE in steroids so if your phone can do Triband you will reach the speeds even with 720 rom but you will not see the spark spinning sun. What you lose with 720 ROM is the WiFi calling.

Great ROM that I'm using now is the C-Rom V7.
[Sprint Samsung Galaxy S 4 General] scottypeterson:
Okay thanks for the response. I'm currently running Negalite Wondex 4.4.2 rom with no issues at all. C-Rom works great for the 720t as well but I tried installing the Super S4 rom and i didn't get any service at all. My signal bars had a red X thru them. Tried re downloading and installing again but i got the same problem. Weird that one 4.4.2 rom meant for the 720 will work on the 720t but another wont..

[Sprint Samsung Galaxy S 4 General] bryguy9021:
Ive put a dozen roms on my phone. 720 roms work fine on 720t which i have. However i do not have spark service here in ohio.. Also check the unified section which supports all sgs4s..im currently running sokp and its the bees ankles. Twrp for recovery
[Sprint Samsung Galaxy S 4 General] conflikt:
What tw rom that has a lot of gs5 features in it and is updated still that works for the L720T? ? Thanks, also what about a custom kernel? I'm rooted and still stock as I'm scared to jack my phone up. Would rather have stock rooted then a bunch of non working features.
[Sprint Samsung Galaxy S 4 General] bryguy9021:
I know nothing of stock and loathe tw... Tried every aosp rom on xda and been rocking sokp exclusivly... However it breaks surfing while talking.. I dont use any samsung apps so i dont knoe if they would work or not if u backed them up. Really overall you gain more features leaving tw but it depends on how you use your phone... What features are mandatory for you?

The only Rom I get to work on 720T is C-Rom 7.1 and that has some issues where it says digital roaming sometimes. It didnt seem to be as good a connection for LTE as stock rom and it dropped to 3G more often.

I had Sacs V3 rom working good with all working stable but then the tethering/hotspot would just stop working for no reason. I was using ktoonez kernel. If it wasnt for that I would have left that rom on. Still Im happy with C-rom as it has nice eye candy.

Is there any other custom rom that works with 720T that is "fully" stable? I need wifi hotspot working.
[Sprint Samsung Galaxy S 4 General] negativzeroe:
No because our phone sucks. Its the spark that you notice the drop on. Because there isn't any development for the T but regular 720 roms work, just lose spark and it says digital roaming. Next time around I'm getting a nexus and being done with all these proprietary bootloaders and different variants. And I'm sick of the connections issues I have no matter the ROM.
[Sprint Samsung Galaxy S 4 General] scottypeterson:
I have the 720t spark version and most roms work for my phone. I'm currently running SuperS4. The spark feature is still there on most roms but the Spark icon is just missing since the rom was not developed with the spark icon in mind. Although the newest SuperS4 does have the spark icon.
[Sprint Samsung Galaxy S 4 General] scottypeterson:
I'm using TWRP recovery with no problems at all. Negalite and C-Rom work great for me as well. I've never had a permissions fail issue. Maybe try re-downloading it or check your MD5 sum.
[Sprint Samsung Galaxy S 4 General] td030981:
Ok Scotty thanks. I'm using Philz recovery. I may have to use the one u have. I want to try that super s4. It sounds cool.
[Sprint Samsung Galaxy S 4 General] scottypeterson:
Yeah it's a good rom but I get the best speed and battery life with C-Rom which is what i went back to this morning. Might be different for you though
[Sprint Samsung Galaxy S 4 General] bryguy9021:
Sokp stable and hotspot works. Digital roaming is just a bug in many roms. Does not effect speed. Changing carrier name gets r8d of it. Doesnt matter our phones are spark at all. Im not in a spark area but have se3n tons of posts confirming spark speeds in various asop 4oms. Ive ran sokp mostly for my daily and my connection to lte is perfect. Rarely drops to 3g when i get in elevator. T9ggle airplane m9de restores 8t. Never drop calls or have any unexplained connection issues. Im on latest firmware and prls and st7ff were updated a month ago

I've personally tested the following ROMs and they all work. These are all the latest 4.4.4 unified builds.

BeanStalk ROM

SlimKat ROM

PacMan ROM

Mahdi ROM (says digital roaming instead if sprint but works perfectly)

I've also tried several other unified builds but don't remember all if them. I'm my experience I've had no problems with the 720t other than a few ROMs saying their roaming instead of the actual sprint network.

But if I could recommend a ROM I would highly recommend BeanStalk ROM. It's completely stable and has just about every possible customization baked right into the ROM including xposed installer. If your one who just keeps the ROM stock or only likes to customize a little than SlimKat is always a rock solid ROM with exceptional support and almost perfect code. The dev is quite a programmer his code is spotless and SlimRoms has several of their own flashable mods and add-ons. SlimRoms also has their own website with all their firmware and software available for download.

Hopefully somebody can clear this up for me so I can get to my flashing ways. I just picked up my L720T today, came from an S3. As long as I keep the stock modem, I can flash any L720 ROM and still get spark speeds in a Spark market, but will lose the notification, correct? I honestly don't see any reason why I wouldn't. I've really wanted to mess around with AOSP and AOKP roms but ran into a ton of roaming issues on the S3. There's a lot of things pushing me towards the S4, and I really want to keep it.

[Sprint Samsung Galaxy S 4 General] JerryGNYC:
I don't know for sure, but I'd be quite suprised to see an AOSP ROM support a vendor/proprietary service like that. Though I do remember on my EVO that some AOSP ROMs had to use compiled binarys taken from the stock firmware to have certain things work properly. Think that was for the WiFI drivers...

And with any AOSP ROM I tried on either EVO, voice quality was always worse than a mod'ed ROM based on a stock HTC ROM.

You can not do this. Android ROMs have no "Live CD" mode. What ROM Manager does is download the ROM for you and then reboot and run an OpenRecovery script to install the ROM, IIRC.
