I was wondering if there was a way to change either
The phones name (jfltetmo) to jfltexx in a simple way (i can do it by flashing roms but that cause me to flash one rom to install another.
Or
Change the roms supported device list to add jfltetmo
Dose anyone know of any way to do this?
Edit build.prop to match the jfltexx values.
I wouldn't recommend it. The jfletmo is a CMDA device, the jfltexx is a GSM device.
While they have the same hardware, CMDA devices use different bands to connect to a network. If the rom is not compatible with your model it means that it doesn't have those bands included.
Force flashing it might break your network connection. Meaning you will not have any at all. Not phone calls, no sms, no mobile internet etc.
I think the jfltetmo is a T-Mobile device which also works with gsm frequencies.

To flash a custom rom to the device, you can edit the updater script to include the tmo.

Thanks, but this id not something im doing lightly. You sedi know a few roms which need a different device name to flash because tmo s4 died long ago
This is for roms such as wizcyan (wich wirk on tmo) just needs another name for it to work.
And as far as flashing goes the i9505 is the device i need yo change to but alot use the xx

I was just wondering which roms allow for using a Verizon sim and a gsm domestic sim such as tmobile used with ease? If there are any does this mean that these roms have the radio edit in them ? Thanks !

Most of them should allow for it. I know dhacker29's latest CM10.1 and ParanoidAndroid builds work fine after making a small build.prop change and adding the APN that you need. The radio edit to enable domestic GSM support is done to the radio partition, not the system partition, so the ROM does not have anything to do with it. As long as you don't overwrite the radio partition by doing an OTA update, RSDLite restoration, etc., you will always have domestic GSM networks unlocked.
most of the aosp roms have a gsm fix for them, i use aokp with a net10 sim with no issue
A friend of mine got a Sprint S4 but he wishes to use it with a GSM Carrier.
First couple things I noted are:
1) No SIM Card Contact Management, had to use an App to copy all to phone
2) Cannot find GSM APN settings to manually enter
Is it possible to flash a stock International i9500 ROM over this to alleviate the issues with using a mainly CDMA version?

I do not believe you can flash an international ROM to this phone unless you want a pretty paperweight. But there are some tutorials to unlock your SIM to be able to use on other carriers, here is where I'd start. However if he's on a Knox bootloader I think the chance is next to zero for using it on GSM because you have to 'go back' to MDC to do some required stuff.
If he wanted to use a gs4 on a GSM network he should have gotten a GSM version not a CDMA

It is actually already unlocked as he can use Voice etc just a bit tricky to get the APN settings to work for 3G...
With the S5 devices with the eMMC 15 chip to aquire an unlocked bootloader, which ROM's from other variants would they be able to use without issues. Just trying to get a thread going for users and Dev's to share their opinions for others to gain knowledge from. Along with Pro's and Con's and 'how to's'. Happy ROM'n
T-Mobile variant seems to be the most supported ROM-wise. It's not locked down to 5.0 TW ROM's like the G900V (Verizon Variant).
The Verizon variant is the most locked down.
That is the question and for any helpful users to post.. Which T-Mobile, Sprint, AT&T(if any) and other variant ROM's can we "safely" install on our device. And what are the Pro's and Con's and the fixes(if any).... i guess this is more like a R&D thread to where everyone can post anything that may be helpful to people having questions of which ROM is suitable since we're now new to the unlocked bootloader and hoping more(the eMMC 11's) will be able to be unlocked as well. I'm pretty new as far as setting up a "guide" type thread. But as info is passed out, I'll try to update the thread for information of the ROM's and Pro's and Con's about them.

Well now that we have an unlockable bootloader... Well, that has to go to AT&T now
To my knowledge, most variants use a generic G900F rom, because those carriers strictly use GSM bands. Verizon and AT&T use CDMA bands, which aren't fully supported in these roms. @jrkruse has released patches (thanks ) that will help with compatibility, but I think these are confined to 5.X at the moment.
I **think** there may be some modifications made to Verizon & AT&T roms regarding firmware, but I can't be sure. It seemed there was more than just CDMA support in the zips provided by JrKruse.
When flashing a G900F rom (should be safe) without patching, you'll probably only have glitchy and cutting out 4G/LTE, with no calling or SMS. Some modifications of the APN settings can maybe help a little, not much. The use of third-party texting apps has been shown to provide some support, but not complete.
Of course, all of this is just based on my strange reasoning, I could be completely wrong on some parts.
Besides cell services, these roms will work fine. Quite fast, too.
As I have stated in the other thread, if a rom is 6.0 and not touchwiz as long as it has a dev build it will boot and work without much more than verifying the apns. 6.0 Touchwiz is simply a no go, just dont try it. It is not worth the headache to get it to work.
I know cm, aokp, aicp, and Resurrection remix all have dev builds there is a couple of others that I think but havent really looked.
@camcorder123 ATT doesnt use cdma technology, they were just dicks and locked the bootloader like Verizon.
@limeaide Oops, you're right about ATT. Sure, a dev build will be easy to run, the problem is that nobody makes them. We've got a few ported but no official developers (from what I know) are actively developing for the phone. That'll probably start up sometime soon but until then we need to find a way to make the generic roms work.
Upon further research, I think it's gonna be a *tad* harder to get G900F roms to work than I thought. The reason only LTE works is because the LTE standard requires a sim card, so there's no problem in getting the phone to read the card and connect to the tower. But, CDMA is separate from the LTE standard - each phone is whitelisted on Verizon's servers (I'm assuming with the IMEI number) and does not need a sim card to access voice and SMS. This is unlike GSM, where everything is through the sim.
So I dunno, we might be stuck for a while. I wouldn't flash roms made for variants other than the KLTE edition, it might be the same outcome even though they may support CDMA.
So I have the Tmobile S7E, and from what I gather all we have is a engineer kernel that allows a Jacky version of root that come with a lot of problems.
With this tho it seem we are able to flash different Roms. With the tmobile sub not very active and having virtually no Roms, my question is, can we use say Verizon or ATT Roms on the tmobile variant? All I would have to do is change APN settings and flash the correct radio?
I've been out of the game for a few years with an iPhone and want to make sure what I can and can't do before bricking my device.
Any guidance will be appreciated, thanks!
Hello everyone so this my history I'm on T-Mobile Network and I have a Verizon v20 unlock phone everything working good just the internet is slowly so I searched about how to enable bands (I can't find something clear ) on Verizon v20 to make it work on TMobile (full LTE ) its this possible ? Is there some mode or something the really work (Unlock bands) like I said already searched but I can't find something really clear
Note : I have just H sign allway on like other user experiment jus show 4g lte for a minute
Thanks on advance
If I understand you correctly, perhaps you need to set up an APN for T-Mobile. It'll be under Settings->Networks->More->Mobile Networks->AccessPoint Names.

Well I already have the TMobile APN and I trying to figure how to get lte because I have only H icon and no Lte (speed) so what the asking is if is possible activide TMobile band like 7 , 12 etc ... Thanks for your reply ?
Well, you came from Verizon CDMA and T-Mobile is GSM. As long as you've got the proper values in the T-Mobile APN (and you got your sim from T-Mobile), I'm not aware of anything else you can do. Could be wrong, though.
Good Luck!

Thanks I'll keeping searching if I find something I'll post here but if someone have a information about how to making work (unlock frequency's band ) more than welcome ?
The ONLY way I could is to flash another carrier or us996 custom rom. The vs995 rom apparently forces the phone to connect to Verizon towers and bands only. Can't edit in any secret menus, nothing, that's the only way I could. Tip, if you want to use wifi calling, flash a custom stock TMobile room not us996
Interesting so there is a way to flash us996 (Spring correct ?) rom on V995 ? Anyone know what's the safe way if is possible ? ?

Flashing a tmobile rom on a nontmobile phone is a great way to brick. Best case it won't boot and lets you flash back, though it could trip ARB as well making it impossible to roll back. The kernel uses a different security key than the other models.
Has anyone tried flashing a Non.Hlos.Bin from which-ever carrier you are wanting to use?
I don't own this phone, I just by chance took a look at this thread.
Yes of course you would need the correct APN. But you may also may need to flash the modem file from the carrier you are wanting to use. ( It can be extracted)
Another option is using QPST.
With QPST you can change the IMEI, add bands, repair a bricked phone, flash a rom etc. These are just suggestions for things to try. Again, I do not have this phone.
Old thread I know, but if you or others have this problem, have you tried using the LG hidden menu (accessed using dial screen)?
*#546368#*996#
If you have the 996 version, just copy & paste. Otherwise, just change 996 to what model you have.
Field Test > Modem Settings > LTE Band Selection
Select the band you want to use/test, then wait a few seconds for it to register. Your signal will drop for a moment, then should show 4GLTE, if you selected the correct one. There may be more than one that works, but one may be more congested.
You should find a list of available bands for your carrier, before messing around.
Also, do not mess with other settings, or you could really screw up your phone I know from experience.
