SIM Unlock S4 i337m or flash firmware? Changing Carriers - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi all, I searched for a bit but couldn't find a direct answer to the question.
I bought a used Telus phone from a friend.
I have a Virgin mobile account and SIM.
If I want to put the phone on Virgin, can I just download and flash the firmware from sammobile.com for Virgin or will the phone still be on Telus?
Note, I did look into the frequencies, etc and all looks to be fine on the hardware front.
Thanks so very much.

SGS I9000M from Canada...

Hi guys!
My brother in law sent me this phone last week (I am in Croatia, Europe) from Canada but SIM card can't work on my network, it's locked on Virgin Mobile.
I did some searching on this forum and longer I search it is more confusing for me so please, if anyone can help and give me right directions for what to do with that.
I'd like to root it, SIM unlock it maybe do some ROM flash if it's possible...
What do you recommend me to do?
Best regards to all and thank you for your answer.
To unlock, you need to be rooted first.
To root, just flash something from the development section, most ROMs there are already rooted. After you flash a rooted ROM on your phone, you will need to pull a file from your phone to edit. Follow the instructions in this thread to SIM unlock your phone.
Your phone is the I9000M but it will work with all the I9000 firmware
thank you very much for your answer.
I've just rooted it with SuperOneClick app and unlocked it with Galaxy S Unlock.
Is it possible that phone looks a little bit slower after rooted?
I need to remove my brother in law's google account now because I don't know his password.
Any Virgin Mobile branded firmware is going to be slow, rooted or not.
As long as your mobile provider in Croatia supports 850mhz/1900mhz then the i9000m will work fine. Head over to the development section, download a ICS rom (I prefer CNA personally), flash a modem more suited to your cell providers, and you're all set.
If you need more info, tell us who your cell provider is.

my cell provider is Tomato, that's something like cheap brand of VIPnet, it's 900 MHz network.
I have to wait a little bit for flashing ROM, it took mi a little more than 10 days just to root and unlock it.

[Q] galaxy s4 gt-19500 compatibility with wind(Canada)

I bought Samsung Galaxy s4 Gt-19500 with Android version 4.2.2 out of Canada. The phone is sim unlocked. My original plan was to get a plan back in Canada and use it there. I found out that it was compatible with Rogers, Fido, and all the carriers who have a band 2600. Wind, Mobilicity, and the cheaper carriers is 1700/2100 and my phone does not work with there sim cards. I searched online and found this link:
http://forum.xda-developers.com/showthread.php?t=2291589 which is also with xda-developers but the download links on the bottom, downloaded 77zip which crashed the computer twice and also downloaded lots other programs with out permission. Is there any way to make it work with wind?
I don't need it to work with Rogers, Bell, Fido, or any other carrier after.
Much appreciated- Tyler
Hello i am sorry to tell you that the GT-i9500 does not have the chip needed to run on the wind net work (T-mobile in USA) the chip you would need is a qualcom chip the only international version that has that chi[ is the LTE variant of your phone GT-i9505 and no you cant swap chips nor can you flash a modem and get rid of that file that is crashing your PC if it does what it claims it does than its a lie and most likely a virus sorry for the bad news but my uncle had the same problem and thats why i have some experience with the phone i recommend you sell that one and buy the GT-i9505 or the T-Mobile SGH-M919 i personally have the T-Mobile version and no complaints just the bloatware but i flashed a rom and no more bloatware
Best Of Luck

[Q] Do I need to unlock to use BTU firmware?

I recently purchased a Galaxy S4 i9505 on EE from Carphone Warehouse, and flashed the 5.0.1 BTU firmware. After I did that I then read I'd need to be carrier unlocked, but I tried calling and receiving calls and messages and using 4g and it worked fine. I also saw some posts about flashing modems. Anyway I'm really confused about what I need to do; should I try and unlock or not. Thanks everyone for your help.
The BTU firmware has no carrier branding, which means it has no carrier logos or bloatware included in it. Other than the lack of carrier doodads, it's the same firmware. You shouldn't need to flash a modem as you already have the latest, from when you installed the BTU ROM. However, the S4 would need to be unlocked for use on any carrier if your SIM isn't an EE SIM. But, you either have an EE SIM, in which case you don't need to worry about it, or the S4 was unlocked by the store that sold it, in which case you don't need to worry about it.
TL;DR: Don't touch the ROM. Don't worry too much about the SIM because you can make calls and use data. You don't need to flash a modem.

S4 i9507 Flashing + CSC

So my S6 had an unfortunate trip in the lake, and I'm going to resort to my sisters old S4 (I owned one too, but I totalled it).
Mine was rooted and had GPE loaded on it.
My old model was an i9505 and noticed that my sisters is a i9507 which is a strange variant (assuming its 4G+).
Anyway, when she had it, the phone constantly overheated and would constantly reboot. We returned for repair many times, each time showing no signs of issue.
What I would like to know is;
Would i9505 roms suit this phone? Or would I have to make do with stock.
And secondly, I am with telstra and the S4 is with virgin (OPS). Is it as simple as flashing a i9507 ROM from telsra on it, or do I have to do something else? This is for the CSC of course.
Is the phone sim unlocked? I recommend sim unlocking the phone before flashing any ROMs, especially custom ROMs as the unlock code needs to be entered using a stock Samsung dialler.
CSC doesn't really matter if the phone is sim unlocked.
Stock firmware is here: http://www.sammobile.com/firmwares/database/GT-I9507/

Hmm stock firmware is only 5.0.1 and not for the carrier that I want. It's been so long since I've modded (since I've had stock S6 since I bought it). Can I change the CSC on that rom, or would it be locked to Optus.
Anyway I've put in my Telstra sim and it seems to work for the moment, picking up the telstra network and changing the APN's to telstras (maybe there is a CSC in the phone for TEL too?).
Just would like to know now if I'm able to use a GEL or AOSP rom for the i9505.
Thanks for the response.
The firmware should not matter. The CSC files are a customization of app for a particular carrier. There are 3 carriers in Canada (Rogers, Bell, Telus) for the s4 and I can cross-flash the firmware with no problems. I would be surprised if the phone can't work with Telstra if it is unlocked.
According to these specs, the 9507 uses a snapdragon 600 chip which is the chip used in the i337m and 9505: http://www.gsmarena.com/samsung_i9507_galaxy_s4_with_s600_spotted_in_glbench-news-6571.php

Understanding flashing

Hi guys,
Just bought a galaxy s5 from my uncle who worked in Canada, the phone was locked to Telus Canada I unlocked it through unlockBase which was superfast and easy.. I have now really started using this phone and have now realised that the date format is different to what I usually use, I have done some research and found that an update stopped the ability to change it to prevent blackmarket sales or whatever.. I was thinking can I just flash a uk rom on the phone or not? But will it relock the phone? Also will rooting the phone enable me to change it? Although I don't wanna root because my online banking app won't work or WhatsApp?
Thanks in advance guys

This is definitely one of the strangest reasons for rooting...
But since it's a Telus phone its definitely a G900W8. You can cross flash all and only G900w8 firmwares so i.e. you can flash Rogers on bell, wind on telus, sasktel on koodo, etc

Thanks for the reply, yes rooting was the last option as some apps won't work.. so if i was to flash it i would only be able to use telus firmware which is US could I flash a UK firmware on it? And if I was to flash it would it still stay unlocked or will it need reunlocking?
EDIT: done some more research.. will changing the csc code on my phone to one of a uk firmware, then installing a uk firmware work?

Nope because anything outside of Canada uses a completely different phone model and flashing between different models will likely lead to a bricked phone (phone is damaged unrecoverable)
