Flashing stock firmware on carrier locked phone - Samsung Galaxy S7 Edge Questions and Answers

Hey everyone! I'm somewhat new to XDA (as in this is my first time creating/posting a thread) but I've decided this is the best place to get some help.
So, I have a carrier locked G935W8 Fido phone, and I was wondering if it was possible to install the stock G935W8 firmware from sammobile. I have read around that flashing the stock firmware works after the phone is unlocked, but what if it is still carrier locked? Can I still flash the stock G935W8? Or will I brick my device? My phone is not rooted btw.
Thanks to anyone that can help me out!

Welcome to XDA
yes, you can flash stock firmware as long as it is for the locked carrier.
Other firmware will work but the imei maybe effected.

Well, that's the thing. I want to flash the unlocked Canadian firmware, as in the one with no carrier bloatware. Will that be possible and have the phone working 100%?

I'm afraid I don't have an answer to your question, but I just did the carrier unlock on my new G935W8 a few days ago using basically the first website to come up in a google search. $25 USD; waited about 18 hours to get the code. You don't have to rely on your carrier (with their insane fees and/or waiting periods) to unlock your phone; might as well just do it. Having an unlocked phone is very handy if you travel at all.

yes, it will work for most things 100 %. volte may not work as it requires a carrier branded firmware.
you will probably have to enter the number for your voice mail manually and settings for internet as that is in the carrier branding.

Thank you everyone for your help! Just a question, what do you mean by settings for internet? As in data/LTE?

Check your phone's active CSC, they usually have the same lock status for every phone.
Easiest method is to use another carrier sim card and test it on your unit.

No, updating the software doesn't change the carrier lock status. If it was previously locked and was unlocked, it will stay unlocked. If you will update through flashing, just be sure that you are flashing the correct software intended for your unit to avoid problems. If you flash your phone with a different firmware with locked csc, your phone will be locked.
Thx Jopat...

This appears to be an unlocked International version for the EU. But the Forum Moderators checking into the update issue.
You can check http://samfirmware.com/ to find what country your CSC code was built for. This is the CSC for Austria (A1) : G900FVFG1ANE1
This senior member says the towelroot works for the G900F

That's what you have to know yourself. If the network you are using has a history of locking the sim, then it's almost 100% sure that your S5 is locked. S5 was well-prepared for its distribution so the CSC of the network is surely fully configured. Look around here on XDA and take note of the firmwares they are using for modding their custom roms, that'll give you a good idea which firmware is easy to configure. You can start reading with gridflash's suggestion.
No...the s3 initialy was locked on VODAFONE UK!i UNLOCKED AND THEN,WHEN I MADE FIRST UPDATE THE PHONE RELOCKED HIMSELF.
THE S5 I BUY FROM A GUY...AND HE TELL ME THAT THE PHONE IS NEVERLOCK.
I LOOCK FOR THE CSC AND FOR THE AUSTRIA IS THE SAME FOR TELERING AND T MOBILE...
AND THE SAME CSC IS FOR AN UNKNOWN COUNTRY...

^Someone told me it works for others too. Anyway, just ignore it, there's a fee for the query when I tried it just now.
Anyway, why not just borrow or buy another carrier's sim card and try it on?

I'm getting very confused which info you really want to know. If you want to know the original and/or current carrier, Phone Info will give you that info as previously stated. Every other details, Phone Info will provide, only exception is the network/carrier lock status.

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)

Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

If your unlocking your Sprint phone for another carrier.

Do not use the stock Sprint software Numbers will not come formatted correctly when you receive phone calls.
For instance when you get a call it should show like this.
+1-808-123-1234
But on the Sprint software with a non Sprint Sim Card it will show like this.
+808-123-1234
So anyone who's saved in your contacts it won't show there phone number. And you also can't easily call them back from your call log.
And this also prevents blocked numbers feature from working correctly.
If you flash the unlocked firmware or you flash the carrier firmware of your choice this issues will go away.

Hmm, maybe this is why Google Voice can't send mms for me? I'm DSU'ed on G935P and using a Mint SIM (T-Mobile). When I try to send a mms from Google Voice, it says mms can't be sent to international numbers.

Nah it wouldn't reverse the unlock status, I'm 200% sure it wouldn't change anything. I personally unlock and flash the latest G955U1 and G950U1 firmware AQH3 on 6 S8+ and 1 S8. It's works great on All US carriers, you can also flash each 4 individual Carrier firmware. I have flash all of the firmware each carrier release on my SPRINT S8's with zero problems. Enjoy
Were did you get their stock firmwares? Looking for,sprints and you used a modified Odin to flash?
Hi, I'm trying to get my unlocked sprint s8 plus to be used on Verizon but no luck so far. Is this even possible.. Any advice would be appreciated. Thanks

Did you ever get your phone unlocked ?
I have a Sprint Galaxy S8+. It has been unlocked by Sprint. I am giving it to my daughter and want to change the firmware to MetroPCS firmware for her. I have the latest T-Mobile and MetroPCS variant firmwares. Do I need a special ODIN to perform this? I'm a little confused because I keep seeing discussions about modded ODIN versions for the Galaxy S8 and S8+

Doubts before buying it on the Software and its unlocking

Hello, I want to buy this phone since I have seen it in amazon for 360 dollars, my question is that it is AT & T software but unlocked for any operator, is this really the case?
I am reading reviews in Amazon that say it is not really Unlocked and can not be used with other operators.
I want to use it in Argentina with the Personal operator.
If it's carrier unlocked, you can use with any operator.

Thanks, for what I see I got confused with that of GSM or CDMA.
Check the only cheap and unlocked version that I see is the one with the AT & T software, is it easy to change the ROM to the Stock to receive updates?
Or is it better to leave it like this and update over time?

But you can't update firmware with any operator, even when carrier unlocked.

Think again what? You still can't update with AT&T firmware. You're talking about flashing to non-AT&T firmware. But that's a workaround.
Carrier unlocking and using on non-ATT network lets you use the phone, but you won't get updates.
UNLESS YOU FLASH TO COMPLETELY DIFFERENT FIRMWARE, which is another topic.
I'm using the att version of the LGv35 using straight talk on att towers and I receive updates periodically on time no issues. So I would think any US carrier that uses att towers should receive updates.

But the op is asking about non-ATT. That's why he wants "carrier unlocked". Specifically he lives in Argentina, so he will NEVER use AT&T... But there's even people in U.S. who don't use AT&T nor AT&T MVNOs.
Carrier unlocked lets you use it in any carrier which has compatible bands, but you won't get updates. For that, you have to manually flash to other variant firmware KDZ
Just for the record, flashing to another firmware variant(at least on this phone) won't get you updates either. You'll need to manually download and flash each new update. I flashed my Amazon variant to the Google Fi kdz and never received another update, no matter how many came out. Had to start doing it manually, got annoyed, and flashed back to the Amazon kdz in anticipation of the Pie update coming out (eventually... Please LG, for the love of...)
As a side note, going from the Amazon software and using lgup to flash the gFi software as an upgrade worked fine, and I kept all of my data. Flashing back to the Amazon software as an upgrade soft-bricked my device and I had to do a full wipe and flash, and so lost all of my data. Reinstalling and reconfiguring all of your stuff is a pain in the ass when you don't have access to twrp for a proper backup.
