So, in my endless mod hunting, over on other carrier forums, people seem to be using alot of different carrier ROMs, by downloading, flashing as normal, then right after, flashing a loki patched kernel. Then modifying the APN to fix the connectivity issues if they arise...
Just wondering if anybody has had the guts to try on a VZW version yet, and if so, how did it go???

Try different modems (If your phone isn't rooted, I suggest you do so to make this easy). Could also easily be a carrier-side issue as it is more than half the time (even tho people automatically assume it's a phone-side problem).

Okay so should root my phone and try different modems?
I never had that problem before and now suddenly it comes and goes.

If you're absolutely sure it isn't a carrier/network issue, yeah. That's what I do if my connectivity was dropping out like that. Try modems bundled with stock roms released by your carrier first. If none of those work, try modems bundled with stock roms released by other carriers in your country. And if you're still having problems after trying those, test any other modem you can get your hands on (there are dozens).
I'd be surprised if one bundled with a stock rom your carrier released doesn't help tho, you'd expect your carrier to fully test roms when they release them, and hope they've ensured the modem bundled with the rom would work for most people using their network most of the time & in most places they have coverage.
Edit - Reason I suggested you root your phone to do this is, it's much easier to flash CWM flashable modems via CWRecovery than it is to flash them via Odin, especially if you end up needing to test a bunch of them. You don't absolutely have to root your phone to do this, but yeah, it could save you a bunch of time potentially.
Extra edit - Might want to also try a clean install of stock if trying modems doesn't work.

An app that will work to do what? No one is talking about any apps here. A modem is not an app. As MistahBungle posted above, a modem is a file which is flashable in CWM or via Odin. Nothing to do with an app doing anything.
In my travels around the threads (here and other sites) I saw a signature for an individual with the SCH-I545 and the modem he had listed was MK8...... which is an international modem I believe. I didn't think anything of it at the time and now I can't seem to find that sig anywhere.
Just wondering this. Did some research and did not find anything solid. Speaking only of the modem... could one flash via Odin the modem.bin files from one of these builds MK8 or MKE? I would guess you would need to make sure it supports CDMA/LTE....
Anyone know for sure?
TIA

I thought this had been asked and answered in another thread, but since you bumped
You've got the problem right. There's several models of the Galaxy S4. They cover different bands and use different modulation types.
I think the I545 has a different radio chip from other S4 models, but even if not, flashing non-CDMA modem firmware is going to break CDMA. Since Verizon is known to do nutty stuff like forcing SMS/MMS to go over CDMA even if LTE is active, who knows what will fail?
Worst case is that you'll brick the phone.
That being said, I don't think the bootloader would refuse to allow you to downgrade the modem firmware back to MJ7, so there's probably a way to recover if it doesn't go well. Notice "probably". Unless you think there's some real value in the MK8/MKE modem, I wouldn't risk it.
I was wondering if there was a way to flash AT&T ROM to work on the verizon model. I know how to flash international Roms but not AT&T.
For example, currently I am running Echoe 32.1 (International version), but when I try to flash Goldenfinger (AT&T) my phone calls work but I get no SMS or data.
Any help is appreciated!
Thanks!
Someone with ROM building (from source or porting) experience can better explain this, but the simplest answer is that because the frequencies that AT&T and T-Mobile operate on differ from those of Verizon and Sprint (typically). So the ROM you are trying to use has different radio drivers for frequencies your phone doesn't use, which results in most or all your antennas to not function. I know that at the very least you need to modify the ROM to utilize the Verizon radios. There may also be some system configurations to be altered in the install of the ROM so it's instructed to use the right frequencies, though a more qualified individual will need to verify that.
Hope that gives you a general idea.

This patch can be used to flash roms from international and other carriers. It has an aroma installer allowing to decide how much Verizon stuff you want to install, anywhere from just the APN's to the full phone & messaging apk's. Read the OP and thread to understand which patch to use and how to use it.

Thank you for the help! But I tried the patch you suggested on two different AT&T ROMs, and I didn't have any luck. It works on international version ROMs, but not AT&T..
And I just realized I forgot to put in the OP that im on Safestrap

Yeah, unfortunately things have been weird with that patch lately. It's a mix of the dev not having time to update while everything has been getting significant updates pretty quickly and lost user interest overall. I've used that patch with AT&T roms before, but admittedly not since Jelly Bean. It should theoretically work still, but there's other variables you have to consider. All I can say is that if you're really interested in running one of those roms, read through the patch thread to see what particular aroma settings and additional zips, etc. people are using to get those roms to boot.
And Safestrap users can use that patch too. I would PM @shindiggity for assistance. He seems like a helpful guy and he uses that patch on Safestrap.

Thank you for all your help! Im gonna PM him and read through the thread and if and when I find a solution, I will post it here.
I've flashed Goldfinger and it does work. These are the steps that I do. Flash rom, patch,signal bar fix, modules and finally SU. In the patch I select minimal and everything else I leave pre selected. First boot does take a couple minutes. Let me know if that works.

I'm planning on flashing my mom's phone to a custom ROM tomorrow, she's tired of all the AT&T crap that's gumming up her phone. It was originally locked to AT&T, but we've gotten the unlock from them, so it's unlocked now and on T-Mobile. Is there going to be any issues putting a custom ROM on it? Will it still be unlocked when I'm done? Any special steps I need to be aware of?
Thanks!

I am simply suggesting you search the forums and do lots of research first. These i717 forums are the best. I'm not on T-MO but I believe there are posts specific to it relating to which rom to flash, rooting procedures, etc. The "Super Everything" thread is always a great place to start.
If your Mom wants stable without issues, stick to a stock based ROM. Custom Roms come with brilliant perks but are not created for your individual phone's hardware like a stock ROM and may suffer in some (specific) ways. Good luck and have fun.

Thanks for the advice, but I want to go ahead with a newer ROM. They've abandonded it on ICS and I think she would benefit from going up to KitKat. Worst case, I flash it back down to stock.
I searched about the unlock, and didn't find anything.

FWIW a search of this forum gives results stating that you must unlock from stock. ( Standard exclaimer: your device may be different, etc.) I believe you can flash custom after that. Most people here have flashed dozens of ROMs on this device, myself included, but we are not all on the same carrier, etc.

I've been using the ZVC modem without actual problems, but i remember the 3G and 4G data being more stable, WiFi faster at connecting, and the GPS fixing faster.
Just to clear things up can anyone confirm if:
- The modem impacts any/all of these things? If so, which ones and why?
- The best modem to use for a Marshmallow ROM?
Notes: I rooted from ZV4 and have been using the supplied modem zips from @engine95. I also update my PRL regularly.

And there in lies the problem.
We aren't able to use KK modems on Lollipop. So I'm surprised we can use Lollipop modems on marshmallow.
Some say all the L modems are the same. But they definitely work differently. ZVC seeming to be the best for most.
It's easy enough to flash and change modems. Just update profile/prl each time afterwards.
The rpm,tz partitions make it even more confusing. ZV4 ones seeming to be best. They can be flashed along with the modem also. But any other than ZV4 seem to cause random reboots and freezes.
Remember, our bootloader isn't truely unlocked. So the way we update doesn't include all the upgraded partitions. We only update modem, kernel, ROM. Rpm,tz partitions are optional.
That's probably also why people are having issues because they are rooting ZV8-C and get all the other partitions which don't work well for us. But to each his own.
I tried rooting ZVC and had to many issues. Went back to ZV4, and everything works as it should.
I haven't tried M yet and probably won't until it's official. Or not. I'm fine with L. So I can't really answer any of your other questions.
