I have scoured the internet looking for an answer to this question but no such luck. Nobody seems to have ever asked/wondered about it. I've seen the guide here about modding the sgs5 to work with virtually any carrier but I assume that applies to US phones. So my question is, could it theoretically be possible to mod a Japanese S5 to work on a US carrier like Verizon, etc? If so, would it work the same way as modding a US one? The problem I see is that the Japanese S5 has a completely different model number than a US S5 but I don't know if that means the tech is different or not.
The reason I ask is because I moved to the US and still have my Japanese phone, but I want to change to a US carrier. The thing is, I have a lot of apps that I paid for and would like to keep them if I can and they aren't available from the US app store nor compatible with US phones. If this is completely impossible I'll take the loss but I thought I'd ask first. :3
I could break down and switch to apple as it's not region specific but I loathe that idea. DX

Hey guys,
I've researched this topic for about a year now and it's hopeless to wait for official sources to do anything about it.
I am looking to be able to do Videocalls over GSM. This means the call does not waste data. This is available in some Samsung phones that sport TouchWiz.
I know it's not a big thing in the US (apparently it doesn't exist), but in Europe, there are plenty of carriers that offer this functionality FOR FREE with many plans simply because it is hardly used. I'd LOVE to be able to do videocalls without having to pay a dime for it, or at least use what is already part of my plan.
I know I'm not the only one wanting this, but I'd like to offer a bounty for anyone who can implement a working, stable version of this functionality to AOSP, but preferably, CyanogenMod. I'm sure I'm not the only one open to donating to this feature, question is, is anyone going to take it?
Hope to hear from all!
Let me apologize for how horribly informed about phones I am even though my study is in a related industry (I'm a computer science undergrad), but I just don't understand all the different terms well enough to draw any proper conclusions as I research my way on getting a Galaxy S4. (I will be getting the Fido S4...so I'm guessing the i337?)
So let me get this straight:
Rooting gives you root access, as with any *-nux systems. So it means you'll have full control of your phone.
And as far as I can tell, only some variants of the S4 are root-able at the moment
Bootloader (lock/unlock) is whether or not you can put in a new (custom) firmware or not.
And so far, it looks like most variants are locked in terms of the bootloader.
Unlocking, I'm guessing in most occasions mean SIM-unlocked right?
What I don't understand is if a device is rooted and flashed with a new ROM. Does that effectively also unlock the sim lock?
Sorry for the weird questions and I know it doesn't seem like it's really S4 related, but I'll be getting an S4 soon so I thought it'll be a good idea to ask in here. More to the point, I'm worried about what it takes for me to get my new phone to the most potential. One thing I'm most concerned about is the SIM lock because there is a good chance I'll be traveling with this phone.
Thanks in advance for any answers.
Maybe it's a stupid question to many, but... I have the chance to order a 32gb korean version of the S4 off Taobao.com, and since I live in China it's quite convenient. The only issue I have is that I refuse to use an android phone without rooting it, and I've been a happy Wanam user for a long time on my S3.
The taobao seller states that 16gb ROMs CANNOT be used for 32gb models AT ALL, but I know better than blindly trusting ignorant Chinese vendors who usually don't know what they are talking about (personal experience).
It does not matter whether it's 9500, 9505 or whatever, this seller has all the models (even 9508 dual sim), I just want to understand if SIZE is a problem or not... Will I be able to just simply root it, and keep using the stock ROM at least? Or maybe I'll even be able to install ANY 16gb ROM of my choice? Or none of the above???
Thanks!
P.S. I searched the S4 forums but found no reference at all to this question...

As long as you're flashing a i9505 ROM to an i9505-like(aka U.S. Carriers variants) device, and an i9500 ROM to an i9500-like device, you'll be just fine. Don't try to flash unlike devices(i.e. i9505 to i9500) though. Best case scenario, the flash will fail. Worst case, you'll brick the device.
Internal storage capacity has never, to my knowledge, had anything to do with what you could or could not flash.

That would be my same guess, although the seller was adamant to the fact that it won't absolutely work (he even declared that he tried himself...). Though I agree with you, I'll wait for some concrete proof, when 32 and 64 gb versions will be more widely available, or at least until someone comes out with a first-person experience of this.
Anyway, thanks

I don't want to call the guy out... but that seller has some very funny ideas; likely he was trying to flash unlike devices. If you want further feedback, I'd suggest posting this question over in the AT&T forums since the 32gb is more widely released. Further, from my past experiences, I've successfully flashed ROMs intended for the Developer Edition(64gb) of the HTC One onto my 32gb.
Let's say, hypothetically, he's correct--the developers who create the ROMs would be required to, perhaps not by forum rules but more so out of "I'm not responsible if you do this," declare their ROMs only usable by certain phones with certain storage capacities?
I will applaud you for taking your time, reading, and doing research before jumping into the fray. Is this your first phone you've rooted?

Not at all, I rooted my first HTC Legend years ago, then my current S3,and so on. Happy user of Wanamlite ROM on my current S3 at the moment. Anyway, I guess our idea is correct. Not to belittle the vendor's experience, but in MY experience PRC people can be quite often very ignorant, or appear so at the very least, and declare the impossibility of an action or a request just to avoid any sort of responsibility in case the crap hits the fan... Think it as a sort of "ultimate disclaimer": I told you not to do it, so if you try and break it it's your problem.
After saying all this, I guess I'm in no rush since my S3 is still working like a charm after more than one year, I'm just exploring the S4 alley since I bough a SUPERCOOL Nolan bluetooth helmet for my bike, I use 2 sim cards at the same time (1 personal=S3, 1 work=HTClegend) and the HTC Legend's bluetooth is sort of fried So I was looking for a way to upgrade things.
I'll follow your suggestion and try to post in the AT&T section as well.
Thanks!
Hey everyone -
Apologies if this has been asked before, but a simple search didn't turn up results. Verizon (surprise surprise) is already lagging behind on firmware updates. For those of us who are S-Off, unlocked, and on custom ROMs, is it possible to flash an updated firmware (such as 1.80.617.1) and still use our phones? Or are we stuck on Verizon's release cycle for firmware updates?
EDIT - I meant to post this in the Questions & Answers section, my apologies. If any mods want to move it, please feel free.

we're stuck on verizon's firmware. i use viper and the software is updated to the latest release, just not using the eu/intl firmware.

If you are on Verizon you should be using Verizon firmware. Just because a version number is different doesn't mean it's ahead. They are different forks tested and tweaked for entirely different networks.

But does that hold true when flashing the Verizon radio behind the other firmware?(not challenging your statement here, just asking a variation of the OP question)
I think that is the main thing people want to know when this topic comes up. I've seen the question and information on it scattered in pieces across multiple threads, but never fully answered by being backed with a report by someone who did it.
So you don't think I am one of those that just sits back to let someone else do the work - I am willing to try such a thing by flashing the US unlocked or Europe FW followed by the VZW radio you pulled, but would need a little guidance in terms of how to provide feedback. Test signal before/after? I know from Viper thread loss of camera is something to watch out for. Any other specific items/parameters to check before/after? Since Viper just did a re-base, I have been searching and debating between those two FW anyway. First the Euro to match the ROM, then the US because they have the ROM flashing on all FW out at the moment.

So here's the thing... you will see unlocked users who simply flashed the radio complain they often get stuck on 3g/1x. You will see the posts about the camera loss. You will see things about loss of volte. The firmware is always optimized for the rom/carrier for which it was written. They won't include vzw fixes in unlocked firmware since that phone isn't targeted for use on the vzw network.
Between the rom and the firmware it's really just a different fork altogether. They aren't mean to be used without each other as a dependency.
Euro firmware will likely have some odd wifi side effects for some folks as they use different bands over there.

So can we back up just a bit to where I believe this all stems from - Is the HTC 10 truly a single-hardware phone? Therein, making all "variants" manifested only by which firmware is flashed? Is that true globally? If not, is that true for all in a particular "zone"(Europe, Asia, US, etc.)?
Ok, with the Euro FW the issues are apparent, given different standards not only for cellular, but also the camera and wi-fi vary from those here in the US. Even if one were to flash a US carrier radio, the camera and wi-fi issues could still pop up. Moving on from that consideration.
For US unlocked, there should be no standards issue, correct? Assuming hardware is the same for atleast all US carriers, what besides the radios would differ between carriers when not running stock ROMs?
Obviously there would be issues when on stock ROMs due to custom apps, features, etc. that would break not only when running different non-stock FW, but also when running one carrier's stock ROM on another carrier's network. All that is ill-advised and goes back to you only recommending stock FW.
Thanks for discussing this. I do not question your advise at all, I just want to explore the what and why of it all to put it all in one place. Thanks for humoring me and my questions!

Hardware wise most are the same. And you are right about me recommending firmware that matches your carrier. That aside, my experience has been like this....
I have been asked a couple times to try to fully convert a phone from one carrier to another. On the 10, we know that unlocked<->verizon works and we thought it would since HTC gave them the same MID (different CIDs though). On the m9, I have attempted to fully convert a verizon m9 to an ATT model. The RUU flashes everything BUT tp and one or two other ones. It boots up fine (att death star and all)... but it will never boot to recovery and never load TWRP when flashed. There's something about the overall partition structure that makes it different.
On the rom/firmware front.... Verizon and HTC do very specific testing for firmware/OS releases. They do this not only to ensure optimal performance for the user, but also to make sure that the phone itself doesn't cause issues on the network itself. As the manager of an engineering team for a huge US based ISP, I can tell you that firmware of devices CAN and DOES impact the network stability from time to time. I'm not talking about capacity issues, I'm talking about your phone making a phone call and causing a network card back at the CO/Tower/ETC reset. It does happen.
Lastly, I measure things by what you gain. What would gain by flashing unlocked or EU firmware images onto a phone on the verizon network? An increase in number version? As much as I see people who change their aboot do so to avoid red text, it always surprised me to see a VZW phone with a third X.X.401.X number on their bootloader indicating non-vzw firmware. There's a new piece of fun around since the m9 and present on the 10. If you manage to get an aboot on your phone doesnt match your firmware and you reboot the phone you will be stuck in bootloader with no access to download/recovery and often OS. The only fix is to manually flash each firmware image / partition file by name manually and it must match the aboot for it to work. So that's another reason to not go and mix and match because to be honest... most people don't make it beyond the panic moment of that. That phone gets returned and added to the reasons verizon makes it more difficult going forward.

There's my 2 cents
Hello all I've been out of the phone modding game for about 4 years and just picked up a w8 model and like the phone though sad to see no cm.
I've been browsing the site and had a few questions about modding my phone.. Several roms specifically say it supports w8 while others just say 935F.. is there really additional code to support the w8 or the rom just hasn't been verified by the developer?
Also several roms say to install the latest bootloader and modem but the link only takes you to the 935F versions.. I already have the latest update from Wind in Canada which ends in API1 is this good enough or do I need to flash a different downloaded version and if so can someone point me in the right direction for the Wind files..
One last thing.. I see a lot of people discussing flashing a csc.. but not sure what that is. I assume it's local carrier settings or something but how often is it needed? And does it only need to be done with certain roms or if there are certain issues.
I've only really used HTC and Nexus phones previously so don't wanna brick this pretty new toy as I bought it second hand and don't have warranty.
Also.. probably not the place to ask but what roms do you guys prefer that supports w8? I'm looking for something fast debloated and lots of customization.. haven't really seen the N7 so not sure about new UX.. I've usually gone cm all the way so used to default android..
Thanks for any info/advice/recommendations
I can't believe this question isn't answered. All samsung line with a pile of unecessary variations is confusing. I just picked up the phone and have no idea, while it should be same cpu=same rom
