[q] [sim unlock] question about unlocking sim while on custom rom - Galaxy S 5 Q&A, Help & Troubleshooting

Hey Guys,
I have a BELL Samsung G5 - G900W8 locked to BELL running CyanogenMOD 12 custom ROM... I seen posts from a year or so back saying that at that point in time you CANNOT unlock your SIM service for any other carrier. Just wondering if this still is the case....
I have my phone customized the way I like it, so I do not want to flash back to a stock ROM and have to do the process all over again (Unless there is a way to save my current ROM, run a STOCK ROM in the background to put in the UNLOCK CODE (IF THIS IS EVEN POSSIBLE))....
Lets see if I can get some good news today!
Thanks in advance

best bet i'd say, buy your unlock code then try it with while under your current rom, if it doesn't work, you surely can backup your rom and flash a stock rom to do it then restore your custom rom.

[Q] changing stock roms

Hi there. I have a Telus Samsung Galaxy S4. I recently unlocked the phone so i can switch to rogers, i was wondering if it is at all possible to replace my telus stock rom with a rogers stock rom.
I'm pretty new to this whole rom flashing situation and i'm concerned about bricking my phone. but on the other hand i wouldn't mind getting rid of my telus apps and getting the rogers ones.
i understand that rooting my phone will allow me to delete apps and what not, but i'm not really sure how to start with all this.

[Q] put stock rom back on s4

I purchased a galaxy s4 off the internet of course.. it is model SGH-M919V and Sasktel is the original carrier. The problem is that it doesn't recognize any simms even ones that doesn't work. i was going to unlock it but the unlock menu doesn't come up with different simms, and the device status is customer.. so from what i have read it is rooted in all likely. so i wanted to put the original rom back on the phone and unroot it. what rom shoudl i use.. and where would i get it..

S4 i9505 Orange need to flash US AT&T rom

Hello!
I bought my mom an inexpensive S4 and it came with Orange wireless service provider and it's in French out for the box.
It's having some problem suck as MMS issues and all that, not to mention it's just being a pain in the butt to work with.
I want to flash the stock AT&T ROM to it ASAP so she will stop yelling at me about it, but I can't seem to find a copy around here. Maybe I'm just looking in the wrong areas, but I would appreciate some help locating it, thanks!
Also, it's been a while since I have done any ROM changes, so maybe showing me how they do it now would be helpful as well, thanks.

AT&T ROMs cannot be installed on your phone. Odin will reject it at best, and you could hard brick the S4.
Unlock the phone by using the service menu exploit, RegionLock Away, or by purchasing an unlock code. Once the S4 is unlocked, you can install an unbranded firmware in place of the Orange-branded firmware. Keep in mind that this phone will never get LTE in the states as the frequencies are different.
Yes, I was made aware of the no 4G, no LTE issue with using a European phone by the guy who didn't know what he was doing when he programmed in the wrong APN settings at the AT&T corporate store...
Supposedly, the company I bought it off said this phone was unlocked already, so what then? It's been about 2 years since I did anything with ROMs, so I might be a little out of the know about the new stuff, thanks.
If it's already unlocked, then you can install any I9505 stock ROM you want. Download this ROM from Sammobile and follow the instructions on that page to install it. It's UK firmware so at the language prompt it will default to English. Be aware that you may have to flash the ROM twice before the S4's wireless radios function properly.
If everything goes as expected the APN should be automatically set. If not there are tutorials all over the place on adding an APN.
EDIT: Download the drivers from Samsung's website if not included in the Odin download on Sammobile. You'll need to have them installed for Odin to function.
Thanks. Now, how can I check to make sure this one is unlocked? Service mode is weird, because I had to do the Q followed by 0000 in key input to get it to give me the menu...
Put your Mom's AT&T SIM into the phone. If it asks for an unlock code then the S4 is still carrier locked.
Oh, okay. It's been working for like 2 months like this, lol.
Aren't there still a few carriers that aren't blocked for other regions? I just want to be sure, absolutely. I just want to know if there's another way to check.
Since it was Orange by origin (and those guys tend to lock stuff) I would say you would NOT be able to run AT&T on it as well (Orange ONLY lock - not really region lock)
When you say AT&T works I would assume previous owner already did what was needed and unlocked this device.
Sounds solid, thanks a bunch, fellas.
I just really wish there were a touchwiz ROM from AT&T for this particular model...
No, no you don't. If anything, you have it far easier by not having AT&T firmware. Unless of course you happen to LIKE encrypted (i.e. locked) bootloaders. AT&T and Verizon lock their bootloaders, which makes the simple things like rooting, bloatware removal, and custom ROMs far more difficult, and in some cases bordering on the impossible.
Your Mom may not give a damn, but by not having to deal with the headache of a locked bootloader you've made your life easier.
I've dealt with several so-called finished custom roms, such as the likes of such as Cyanogenmod and others, and lets just say they aren't quite as solid as the stuff that the phone comes with.
There's always something that doesn't work like it's supposed to or some important app that won't work somehow. Last time, I went with a stock rom, custom recovery (I like TWRP) and rooted the device and it ran just like I wanted. SO yeah, I'd like to use a stock touchwiz rom for the US if it's available somewhere.
I understand not wanting to toss a custom ROM on the phone, but that wasn't the point of my post. The ROM I prompted you to download several posts upthread is a stock Touchwiz ROM. In fact, up until this morning it was the same ROM I was using on my O2 I9505 that I'm using here in the US. As the I9505 is not available and never will be available from a carrier in the United States, there will never be a US ROM available for this phone. The ROM I had you download, unlike the AT&T ROM, has no carrier branding of any kind, no carrier bloatware, and no locked bootloader. As a result, you don't have the carrier meddling around with the ROM and making the experience worse by having crud added.
My point is, bluntly, that you're far better off now than you would be with an AT&T device. So, hopefully, now that you got everything sorted out your Mom can enjoy the phone.

S5 AT&T help

Hello guys, I'm posting this for first time.
My girlfriend is having a Samsung S5 from AT&T and I want to root it as she told me system apps from AT&T are taking too much space on her phone and so I was thinking can I flash any custom rom on it?
As I see the AT&T thread separate, I want to ask some things
Does Network provider has to do something with it ?
I can flash custom rom on her phone or not?
And same odin thing works ? Like unlocking bootloader and fishing custom recovery
I have never rooted any Samsung phone ever
I'm having a oneplus and HTC.
If anyone can tell me what all do I need to do, I would appreciate it a lot .
Att version has locked bootloader .... Root is possible and there a few roms but they are all based off the stock rom just tweaked a bit ...

You should consider two things:
1. ATT phone may be sim-locked (locked to their network), but it has nothing to do with custom firmware. This problem may be solved more or less easily.
2. ATT phone (SM-G900A) does have a locked bootloader. This is a real problem.
That's why you're limited to touchwiz-based ROMs and stock kernels.
This means, in it's turn, that you cannot have root on 6.0 and above, you cannot have custom recovery, LOS, etc.
If it was my device and I was going to use it as a smartphone (to communicate with others) on a GSM network, I'd install this ROM in unrooted variant and the latest firmware (boot, modem, kernel).

It's been over 2 years for her phone, unlocking bootloader won't be an issue ( we can unlock it right?) . And she will be using AT&T only because she is using family plan.
If you dare saying the real problem is locked bootloader then we can just unlock it , or I understood it wrong

I believe that the following thread may help you out with this. It's S5 AT&T device specific.

Revert SM-G900M to trade in with Samsung

I have a SM-G900M, which I've installed a custom ROM g900mubu1cpc4 couple of years ago. Now I'm trading it in to Samsung for to get credit towards a newer phone. I see a lot of stock ROMs available, and not sure which one to choose to revert the changes that I don't remember
Is there any way to figure out which country stock ROM was originally on it? I've read technically it doesn't matter, but since it's going back to Samsung, I want to be precise.
Can someone remind me what else I need to revert the phone beside the ROM? I remember something about locking/unlocking the bootloader, but not sure if ROM would take care of everything.
Thanks!
