Hello. I've just ordered my 1+3. I was overhyped, and today I was told it's not an European variant (A3003) but I assume it's Chinese one (A3000). If it's really the chinese variant, it's not really that bad because my country supports LTE Bands 1, 3, 7 and 20, so only 20 will be missing but it's still far from being spread here so... But if it's north american one then I will have big problem cause there is no 1800MHz support... I have big question - will I be able to flash all the ROMs on it without problems? Or my modem/IMEI or something will mess up upon trying to install for example CyanogenMod? Thanks in advance for the support
No you can flash all rom without changing any modems and radios.
You find every guide here on xda after unlocking and flashing twrp make efs backup first.

Hi XDA,
I am currently on a T-mobile contract, but I will move to a different country for business purposes.
I know how to do the device unlock (thanks to youtube), but I was just thinking of different issues that
might come across when using different GSM network.
my device is rooted, running custom rom with T-mobile radio.
my questions are:
1. even if i unlock my device, shouldnt i flash a different rom that is compatible to other networks? (different radio too?)
2. could i use the roms and radios that are used in international version?
if the process is more complicated than I am thinking, could someone light me up?
Thanks in advance.

Never flash anything from an international model as you will brick your device.
Hey folks. I'm really tempted to get the T-Mobile S4, have it unlocked so I can take it to AT&T but I know at some point I'll be doing custom roms and probably radio upgrades since they come out once in a while. But will doing any of that break the SIM unlock? The one I fear most is probably radio upgrades but I've never moved a phone to another carrier so don't know all of the implications. Roms I doubt will be an issue but anyone know or have previous experience? At worse I have to keep calling T-Mobile to get it unlocked again if radio upgrades mess it up but I'd rather not be calling them all the time and if it is a problem then maybe I need to rethink this a bit more.
No, when you unlock it, it will be permanently unlocked, even you restore to stock rom, flash any other rom, radios, recovery or anything to OS or software related.
Before you flash a rom, make sure to try it in another provider with the factory/stock version, so you can make sure that the phone is working fine since the beginning,
T-Mobile S4 (SGH-M919) has a lot to offer in connectivity such as LTE Bands 1/2/4/5/7/17; in HSPA+/UMTS: 850/AWS/1900/2100MHz and finally GSM: 850/900/1800/1900MHz, so it surely will work on the AT&T network.
While the AT&T S4 (SGH-I337) only has LTE: Bands 1/4/7/17; HSPA+/UMTS: 850/1900/2100MHz; GSM: 850/900/1800/1900MHz.
For unlocking your T-Mobile S4, here is the link to the new T-Mobile Unlocking Policies: http://support.t-mobile.com/docs/DOC-1588. I bought my new S4 recently and they declined to unlock it before the first 40 days (postpaid) and before the first 60 days (prepaid) and there are certain other requirements to comply.
Lucky for me I found a trick on this forum to unlock it without the subsidy code (since my requests were rejected), it worked flawlessly and even I restore or flash any stock or custom rom, the unlocked state stays permanently because it's based on the NV system, just don't mess up with the NV base system.
If you want a phone with full LTE bands coverage, go for the M919 and it's bootloader unlocked from factory unlike the AT&T version which is bootloader locked. So, you can't go wrong with this model.
In terms of performance, the international version I9500 (without LTE support) is faster than any other S4 with SnapDragon 600 processor, I tested it myself since I have both I9500 and M919, the I9500 is octa-core (4-core of 1.6, and 4-core of 1.2) but only 4-cores work at the same time, in order to have a better power management, but even works in 1.6, it's a little bit faster than the 1.9 from SD600, i noticed on the graphics performance too.
And custom roms and other mods will come thru time for this specific model, just be patience, I have my M919 working with a non-US carrier sim card and installed custom rom Wicked v2 and it's working fast and stable.
I hope this info help you to decide!
Cheers!

Hello!
i have an Verizon s-off M8, My question is if is possible to convert (change CID/MID) in to a HTC Europe (with a last firmware). I use it only in gsm band. it is possible?!
Nope, as it's a CDMA device not GSM

Sorry to ask this like a month later, but I had a similar question as the OP. Why wouldn't it be possible if I only wanted to use my phone in Europe on the GSM bands? I've been using it with a ROM for the international phones and it works fine. But I was also wondering if I could flash the newest firmware and 4.4.3 upgrade to use some of the newer ROMs for the international versions, like ARHD 10.2.

HI! Can you give me more details? I've just received the verizon variant (bought from an online store) in Europe.. I would like to "convert" it to international version so I could get official updates from HTC via OTA. IS that possible?

I don't think you can convert it over to the international edition, although I could be wrong, since some of the partitions, firmware, and actual hardware (like the CDMA receiver) are different. Given how buggy just some of the ROMs are with the int'l kernel built in, I would be worried about bricking the phone trying to actually convert it to be able to receive OTAs.
What you can do check out some of the ROMs that let you pick which variant to install. After you boot that up once, you'll probably need to reflash the stock VZW kernel (or read around and see if Verizon users got other kernels to work with the ROM). It's kind of trial and error. A lot of times I ended up without wifi or service until I found a kernel that worked.
For updates, (this part sucks) you'll have to wait for the Verizon phones to receive them in the US. Someone usually makes a set a files you can flash since we can't get the OTAs for VZW here and a lot of people don't want to go through the hassle of going back to close to stock to get them. Make a backup, flash those, and go on your way!
But, you'll have to follow the updates and such for VZW phones and then just use a ROM to make it like an int'l versions.
I've been running the int'l version of Paranoid Android and before that ARHD and it's been fine. I used venom and I think n8 before that but it would only install the VZW version so I had to use ROM Cleaner and take out a lot of crap. The roaming triangles were annoying enough that I gave up on venom even though I like the ROM.

THanks for the reply. I think I will return it back.. I wanted a stock experience (eg: when HTC launch an update I DONT Need to wait for verizon to release an update).
I paid lots of money (~700$) for a contract free phone and got a branded phone (not sim-locked by branded is enough) . What a sh*t situation.

Oh God, I assumed you got a Verizon one because it was cheap. I picked mine up in the US for $150 so I don't care so much about having to wait since I saved so much money. If you paid full price I would definitely return it and get an int'l one instead!

Nope, the problem is that I wanted the 32 GB version and most of the online shops had only the 16 GB one. Maybe there is no international 32gb htc one m8..
PS: the retailer's product page (cel.ro) doesn't say anything regarding branding, even the photos are of a htc one m8 unbranded phone.
I am a bit late here. Can i flash a European custom rom on verizon M8? I want to completely get rid of verizon bloatware/services . If yes then while installing custom rom in aroma can i select WWE instead of verizon?? Summary of my question is can i use a WWE European custom rom on version M8??

You should only use custom ROMs that specifically support the Verizon variant. If the option is given in AROMA for carrier version (and VZN is one of those), its got nothing to do with what carrier/region you are located in, but refers to the version M8 you have, which is still Verizon. But you should check the specific ROM thread for details, comments by VZN version users, etc. as devs don't always setup AROMA the same way.
This thread is really old (almost 2 years) and we know a lot more now. FYI, I know its not what you specifically asked, but the topic of the thread is converting to Euro version by flashing firmware, RUU etc. And quite simply and frankly, do not attempt to flash Euro firmware, RUU, or change the CID/MID to do so. Flashing Euro firmware on the VZN variant will result in a radio brick, and the damage may be permanent!
I've searched and can't find a specific answer on compatibility on ROMs and the different carrier versions of the Fire Phone. It's late so maybe I just picked bad combos in my searches.
1. a. Will it brick an AT&T phone if you install the international ROM (or vice versa)?
b. If it doesn't brick is it effectively turn into an international variant (or vice versa)?
2. Are the CM11/SlimKat ROMs ok to install on any variant (AT&T and/or International)?
3. Are the CM11/SlimKat ROMs ok to install on any size variant (32GB or 64GB)?
I know some phones it's OK and some phones brick when you install other variant ROMs so I just want to confirm before I buy an AT&T version. I also know some ROM's have to re partition the device and I wouldn't want to lose 32GB. I apologize if these have been answered but I can't find them tonight.

I have the exact same question 1, I wouldn't call it "international", just unlocked version I guess
Bump, such easy question should be easy to answer and kind of important

1.a. No.
Source: I installed the UK, US AT&T and US GSM unlocked firmware on my device (T-Mobile netlocked, Germany).
Every Fire Phone works with all variants in general (there are ofc. different pre-installed TTS languages, WiFi channel support differs, etc.)
1.b. As Jose-MXL mentioned, unlocked (as in neutral) describes it a bit better.
The US ''GSM unlocked'' firmware has multi language support, just like the other versions, so you're not stuck with English language.
Again, some WiFi channels won't work, e.g. channel 13 in Germany, because it's based on US standards.
The fimware doesn't affect netlock, ofc. If your device was netlocked before, it will stay locked. If it was unlocked with a code before, it will stay unlocked.
2. Yes, as far as we know.
ggow only mentioned v. 4.6.1 because this was the (latest) tested version at the time. People reported successful installation on 4.6.1, 4.6.3 and 4.6.4 variants.
3. Yes.
Only the system partition is affected when installing SlimKat / CM11 (sorry, just describing it very briefly ^^).
As you know from stock Fire OS, the internal storage and media storage share the remaining storage space, so nothing will change on that partition.
Ok so I really y need your help guys!
I've asked this question a few times in the past about other phones I ended up not keeping, but I'm now intent on making this work.
I'll keep it simple: can I flash a Canadian CSC on a Global phone? Will this brick the phone?
I don't quite fully understand how the CSC relates to everything else, but the times I tried I couldn't get the CSC to change. Plus I'm concerned because I have a dual sim model (which doesn't exist in Canada) that is Exynos, where the Canadian model is a SD.
Through my reading I think it could work but I don't want to have a $1000 paperweight in the end, but I'm have piss-poor reception, Samsung Pay doesn't work, VoLTE doesn't work, I can't block phrases in SMS and the list goes on. I want to try this to see if it helps anything... Failing this I may cut my losses, sell the phone half-price and just get a non-Samsung device; I'm getting so aggravated at this it's not even funny.
Thanks!
PS: if you are wondering why I didn't buy a Canadian phone to start with, let's say it's a complicated answer but can be summed up by the dual SIM cards.
A CSC defines that carrier settings of the phone. As long as you use official Samsung firmware and do it properly it will not brick your phone. Look at sammobile first to see if Canada has a stock firmware. However, doing this will mean all data is lost, are you flashing carrier based firmware or your country's global software?
I just did a search and on the S8 there was no difference between the single sim and dual sim softwares and on GSM arena it classes them as the same. Do you the have snapdragon or exynos version?

I don't mind data loss, I have back ups and really not much on the phone anyway. Canada has stock firmwares for each carrier, so to answer your question, carrier based. But my huge deal here is the different configuration between what is available here and what I have: I surely can't flash the entire firmware based on a canadian phone... I would lose my dual SIM and surely the difference processors would brick the device. But I'm not really sure if I can mix and match, i.e. pick a CSC for my carrier and everything else (PDA), and if I can, what do I chose?!
See where I'm at... because I can't flash the entire firmware I think I'm s.o.l.
I'm afraid the situation isn't that good for you.... I am assuming you have the Exynos varient since I cant see a dual sim version of the snapdragon variation which means no Canadian firmware is available for your device at all. Since I'm in the United Kingdom we usually swap our CSCs with ease but it appears if you didn't buy the snapdragon version your out of luck at least for now. I'm sorry I couldn't be of more help you could sell and get the Canadian version but you won't be able to dual sim or get another phone I left from the S6 to oneplus and had a really good exprenice but that was on the 3T so I'm not sure what they are like now
Again sorry I couldn't have been more help:crying:
