Pros and Cons of ROM's from other variants - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

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.

decision to buy htc one developer edition

hey guys .i just pre-ordered htc one developer edition.what do you think i get the benefits purchasing the developer edition instead of at&t version.
do you think it works with at&t and t-mobile lte networks ?
will i get the software upgrades first like the international version ?
normally the at&t version device get upgrades very late compared to the international version devices.i always wanted to buy a device which works on every kind of gsm networks(hspa+,4g and lte ) in usa and internationally(3g,4g and lte).and which gets the software upgrades right on time .i thought this would be the one .
someone clarify me the choice i made was right

If you want non bloated att software, possibly faster updates, and bootloader unlockable.
Lte will work for both networks.
Updates will probably be quicker due to the fact that there is NO carrier testing. So updates should be fast as the international version.
Sure why not!
There is an entire thread dedicated to this. The dev edition had an unlocked bootloader and SIM. It will only function on AT&T correctly at the moment, but later this year tmobile should have enough of their lte and refarmed hspa network up for it to work properly on there.

The benefit of the Developer Edition is the unlocked bootloader (allows you to use custom ROM), and the unlocked sim (which ATT won't unlock for you even if you buy outright).
Since it is a non-branded handset, it should allow you to upgrade your software like the international version, although this is not as important if you use custom ROMs (since Custom ROMs usually updates as new software is released).
The Developer Edition will work perfectly with AT&T for HSPA and LTE as it is identical besides the branding and unlocked status. It will likely work with T-Mobile's LTE when it's ready but will not work with the 1700mhz HSPA+ network. It may however work in areas where T-Mobile uses 850/1900 frequency (Not everywhere at the moment)
So in terms of advantage over ATT version, the Developer Edition is much much better as it allows you to use customs ROMs (since you are here asking the question, I would assume custom ROM is something you would like to use). SIM unlock is not important to everyone as most will stay with the network anyways, but the lack of custom ROM ability flat out makes it the less desired version.

Well, you asked the questions and I answered them for you (the differences should be black and white for you). Whether or not if it's the right decision is up to you.
32gb or 64GB? Worth the extra cash?

Hi:
I know this thread is about the dev edition but I was wondering if there's any other difference between the 32gb and 64gb dev edition? I know the dev edition has unlocked bootloader, but couldn't we achieve the same thing on the 32gb unlocked edition using this method (htcdev), or am I wrong? Thanks for your help :fingers-crossed:

Yes, it can be unlocked via HTC Dev. Only the AT&T branded devices will be blocked.
Edit: according to your post title, you're asking if dev edition is worth the extra money? YES. Not even $100 more for double the storage.
You can unlock yes. Your getting a extra 32 GB basically

So the dev version doesn't have custom roms, or very little custom roms? If so why would that be? I love flashing roms, but this would be a real bummer.
Nevermind...I read it incorrectly. The Dev version does have custom roms. How are the custom roms different on a dev phone than lets say the sprint version?

The Sprint version of the phone has different hardware as it is a CDMA phone, not a GSM phone. You could potentially brick your phone by flashing ROMS that aren't for your specific device. Stick to this forum for your mods and ROMS/kernels.
Make sure that you install a recovery (CWM or TWRP, both located in the Original Android Development section), which is necessary before you begin to flash anything. Again, ONLY FLASH MODS FOR OUR DEVICE FROM THIS FORUM
this might not the right place to ask this, but does anyone know if HTC will be releasing a developer edition in black?

[Q] 900V options

Hello!
This might seems a little strange but I can't seem to find a straight forward answer. So everything I read, talks about the 900V being restricted due to it's boot loaded being locked and there are very few options with choosing ROM's. Is this common:
1) I have the 900V and i have safestrap 3.75 and Alliance Rom 2 with NE9 kernel, currently not in the states and i'm able to use a different sim card. It is using a 3G carrier vs Version LTE, my phone still says sim locked to Verzion but i'm connected to the current SIM card and pulling data off of it. I did not think this was possible with Verzions choke hold on everything.
2) Am i truly limited on what ROM's i can load on my phone? I feel like having safe strap i should be able to install more ROMs than the few options listed on here.
3) I enjoy the Alliance ROM a lot, any recommendations on what ROMs i should experiment and might enjoy. And can i install them with safestrap?
Thank you all for your time!
All Verizon phones are unlocked but the bootloader is locked. This means only stock ROMs will work, and they've locked out most other carrier's LTE bands.
stick to Verizon development thread and try all of them there.

Flashing Non Verizon Roms (i.e., from unified development roms), possible?

Hi Guys:
I don't want any Verizon related software on my phone, since I am using a different SIM. Am I restricted to flashing only the roms located in this forum for my S5? Or can I flash any of the Cyanogen or unified roms to my phone?
Anyone?
Is your phone unlocked? Or do you have the retail version? I'm just going to make the safe assumption that you bought the retail variant, therefore your answer is NO.
If you have the Dev version then have at it...
No one with a dev phone would need to ask. So no
Great thanks guys. Yeah it is a retail version not dev version. Damn that sucks.. whenever I dial *611 it still goes to the Verizon customer service line. I can't seem to change that even after uninstalling and freezing as much of the Verizon stuff on the phone. Any ideas
Buy a nexus!

Other S7E Roms for Tmobile variant

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!

T Mobile One Plus 6T Unlocked and Bootloader unlockef

I'm just having a really hard time finding an answer. I just had a OnePlus 6T T Mobile edition find it's way to me. It's carrier unlocked and Bootloader unlocked and it's running the latest T Mobile version 10 OOS. Since the bootloader is unlocked, can I just flash the latest non T Mobile OOS Android 10 version to it? In other words the US 6T edition? Or must I use the international version? I'm really confused and sure this has to be answered somewhere but just can't find it. Can anyone help and point me in the right direction? I have lots of experience flashing ROMs, but this one has me stumped at this point. Thanks.
I'm no expert... lol, but based on what I do know, I believe these are your steps...
So I'd take a look at this post-
[T-Mobile / Guide] - Full SIM and Bootloader Unlock + Root for locked devices
Background: I am writing this short guide for people like me that want all the info about the T-Mobile 6T unlock capabilities. None of this is my work. I wanted to have a central thread where T-Mobile users can discuss the T-Mobile specifics of...
forum.xda-developers.com
Follow Step 4, and then from that point allow the ROM to update via OTAs. The MSMDownloadTools are basically a fix-all, but set you back in time update-wise.
I do not believe there's a full TMo ROM for the latest updates, but once again, I could be wrong.
You could also use the International Version if you want, that is what I am running now, but if you want root access, I believe getting 11 working has some extra steps/workarounds (so i'm still on 10)
I initially changed to International because of quicker security updates and it works fine, no issues to complain about, but my wife (on TMo stock) seems to get better signal than I do in more rural areas.

Thanks for the input. I have seen all those threads, but the main purpose there was for people who did not want to wait for the SIM unlock. That got them past that and also got them so they were able to unlock the bootloader. I already have an unlocked SIM and unlocked bootloader. So I know I could load up lineageos if I wanted to without doing anything special. I would think I should be able to use TWRP to put the International version on using TWRP. And maybe the US version. But that may not be the case.
It just seems like any work on this device stopped after the above. Of course once you are bootloader unlocked, there may not be need for much more and people may just move on to other ROMs.
Thanks.

The more I search, I guess that it appears there are some privileged partitions. This method you mention gets around that irrespective of the SIM and Bootloader being unlocked already.... Sigh....
