S4 i9507 Flashing + CSC - Galaxy S 4 Q&A, Help & Troubleshooting

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.

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

[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.

network unlock or modem swap i337m on 5.0.1

Hey people, I have an issue going on here.
I was going to unlock, but decided to reflash firmware and change the csc from rogers over to bell.
Kies recognizes the phone now as being a 'bell' phone, and have done an update just to confirm it but it still will not accept a bell sim. Every time I have inserted a bell sim it requests the 4 digit unlock code. The sim works just fine in my S3 and another bell S4, so that is not the problem.
All settings in the phone also show it to be 'bell', home screen and all, so the csc did take.
All the modems/firmware on sammobile are multi-csc, as i have tried to just flash the modem alone after I extracted it.
I could care less about being truly carrier free, as I am locked into a bell agreement through work.
Any suggestions on this, or do i have to purchase a code? I assume its locked now so I cannot downgrade to my understanding to a lower modem to use the service menu to unlock.
Thanks for the input.
I've flashed from a Bell 4.4.2 to Telus 5.01 without issue and the phone will remain sim-locked. The only difference I have seen between the Bell, Telus, and Rogers ROM are the carrier apps included with each ROM.
The sim unlock code is 8 digits long.
You should be able to downgrade the i337m's 5.01 stock ROM to a i337m 4.4.2 stock ROM. Then install the 4.2.2 modem, root the phone, run region unlock app, re-flash stock 5.01, and the phone will be sim unlocked. Doing this will trip the knox counter to 1 and void any remaining warranty.
I tried to downgrade, but it didnt take. I will try again. I know there was a discussion on booting the phone and not signing into google then reflash again. Is this needed?
Thanks for the reply.
Well, I got it to work this time. Much appreciated
You tried to flash a stock 4.4.2 rom from sammobile.com? Were there errors in Odin?

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)

Flash Tmobile stock rom on SM-G935FD

Hello,
As the title says, I'd like to flash the tmobile stock rom or perhaps the tmobile variant of the SM-G935U on my SM-G935FD. Tmobile is my service provider and I'd like to be able to use wifi calling and samsung pay. I know I can flash these roms without issue, but I was wondering if it would be possible to revert back to stock SM-G935FD firmware, since the tmobile ones have locked bootloaders.
Would it be possible to either flash stock SM-G935FD again or do a hard factory reset?

You cant do it, odin will not allow the wrong firmware to be flashed.
And in the this case your talking about flashing firmware from a snapdragon devcie onto a exynos device.
That alone should have been enough to realize its not happening.
Your far better off with exynos anyway, locked bootloader on the snapdragon version...that is crap
Sent from my Note 7, S7 Edge or S6
You can setup and use Samsung Pay on an international device -- check the Samsung Pay thread . I have the DBT (germany) CSC on my phone; before that I had XSG (Saudi Arabia); and both times I have successfully used Samsung Pay.
Wifi Calling won't work AFAIK.

No LTE after change rom

Hi,
I had bought a Canadian s4 on ebay with version 4.4.2, I had root it for unlock the Italian language, and worked fine for two years but without ever receiving the H + and H bands, he was always on LTE or 4G...
A month ago I decided to do an upgrade it and factory reset because te phone had become very slow, so after total wipe I downloaded the stock Lollipop I337MUMUGOH3 Trinidad & Tobago (because unlocked and more native language) and flash it with Odin, but after the softkeys have not worked ... I tried some other stock rom without succes, with I337MUMUFNE2_I337MUUBFNE2_TTT 4.4.2 the touch is coming back to work even if typing * # 2663 # the phone shows fw version is 0x10 and the part's fw version is 0x1a and can't get touch fw update (IC's F/W is higher than Bin's F/W), but I lost LTE bands, now working bands are always H and H+ and never LTE or 4G ....
I tried to install different modems taken from other stock rom, but without success ...and QPST show me all bands enabled...
Maybe i must change the baseband ??? Witch baseband? And how can i do it??
How can I get back the lte without losing softkey? And how can update the softkey fw?
I do not know what else to try :crying::crying::crying:
Thanks in advance..
I recommend not trying to flash the AT&T s4 sgh-i337 firmware to the Canadian s4 sgh-i337m. If you are able to flash the stock AT&T firmware onto the Canadian s4, you will have a locked bootloader.
Did you change your cell provider? Does the sim card get LTE in another phone?
You can flash the stock Canadian LP ROM from sammobile.com to see if the buttons work properly.
I recommend not upgrading the touch firmware at all as there is a chance it will disable all touch functions.
But my model phone is SGH-I337M!!

The sgh-i337m does not have a locked bootloader. The AT&T s4 has a locked bootloader so flashing at&t firmware to your Canadian s4 could result in a locked bootloader or a bricked phone.
There are no stock ROMs for the at&t s4 above 4.1.2 from sammobile.com like there is with the Canadian version.
It's up to you If you want to flash AT&T firmware to the Canadian s4.

I'm confused, I need some advice how to restore lte bands on my phone without broke the softkey, I did not say want to flash the ATT firmware....
Some ideas?
I apologize for referencing the AT&T firmware. I misread your original post.
Have you tried flashing firmware for a Canada. It doesn't matter whether your flash firmware for Rogers, Telus, or Bell as long as it is at least version OH3.

But the Canadian firmware not work properly in Italy, I used it for 2 years without H bands, the TTT firmware is for the same phone but is open, maybe I must change the csc?
I suggested flashing the Canadian firmware to see if the firmware fixes the problem with soft keys. Once that is fixed, you can try other fixes to get lte.
You can flash the stock Canadian lollipop ROM and change the csc by dialing *#272*imei#.
