Couple Simple Questions on Reflashing Firmware in US... - Sony Xperia XZ Premium Questions & Answers

Good day all,
Some questions I have that are wandering around my head...
I just got a US model XZ Premium G8142 Dual Sim from Best Buy, will be using it on AT&T postpaid with LTE service.
1. Will re-flashing firmware from US to Central European 1 (CE1) firmware cause my device to be considered "rooted" or "bootloader unlocked" and have features removed? I don't want to have a rooted device as I do like the camera features on this phone. I'd like to keep it as stock as possible while enabling the Fingerprint Sensor.
2. Will re-flashing my device with CE1 firmware cause this phone to not play nice with AT&T's LTE bands? I saw somewhere that I'd have to change a "carrier file" somewhere in some partition, but I have no idea if this would apply to my situation.
Thanks for any responses and hep you guys may give!

1] No. Your phone will still have its bootloader locked and will not be rooted.
You have to go to the Sony developer site and request an unlock code if you want your bootloader to be unlocked. So it's not something you'll end up doing accidentally.
2] No. The band support remains the same.
Playing nice with AT&T on the other hand is apparently iffy. I don't have AT&T, but some have been stating that you sometimes have to jump through some AT&T hoops to get LTE working.
Some have said that you need to give them your IMEI and tell them to enable LTE for it.
Others have said that if you have an AT&T phone with active LTE on it, you can just put in the SIM from your old phone and LTE works.
All of the OEM partition, carrier stuff is directly related to getting Voice over LTE and Voice over WiFi working on T-Mobile.
That doesn't apply to AT&T since there's no way to get VoLTE working on that carrier.

Help with Sony Z5 - WIND

Hey forumers I'm a little new here so sorry if this is a huge noob question
Yesterday I bought a Sony Z5 outright from a local provider here in Canada and I had gotten it unlocked and such but it doesn't seem like I'm able to find my local WIND network.. after some research i found that this phone might not be compatible at all
I had gotten a couple hints that maybe if I root I can unlock the band or something... I don't know.. if anyone knows what I can do please let me know.. I rather like this phone aha
TLDR/ Looking for a way to get Sony Z5 Compatible with WIND
If you already unlocked the sim and it doesn't work then it doesn't work. Should have checked the network bands before purchasing. If you don't know you can ask one of the wind representative. Also, if I remember correctly you might need root or worst you need to unlock the bootloader (which you can't because it is from bell), to unlock the other bands. All I know is that unlocking bands require alot of coding and complicated procedures. Gl bud, return it if you can if it doesn't work out.

Is there a reason why BELL cannot unlock the bootloader? I've been doing a lot of research since I posted this thread (im becoming obsessed even as a noob) and I'll need to root the phone, install custom kernel/ROM and edit 6 values into the non volatile memory in order to gain access to add additional bands. The Chipset in the Z5 should in theory allow AWS bands..
Make sure your APN is correct before going through all that trouble. Unlocking bootloader on Sony phones renders some special features useless.

Thank you!
I have triple checked the APN settings to be perfectly compatible with WIND and that is not the issue.
So pretty much either i lose out on features in order to root - unlock the radios
or I return it and somehow get the Z5 DUAL.
I really love this phone and can't think of any others to get if I return it and don't go for the dual lol.

As far as I know, here in Canada when ever you get a phone from a carrier the bootloader is locked forever. Blame the carriers not sony. And from my years in XDA - sony in particular I don't think I have met a developer skilled enough to get the bootloader unlocked on non unlockable devices, maybe Samsung devices yea but not sony.
Installing custom roms and kernels would require you to unlock the bootloader which you can't do so with carrier phones. This is the down side when you get carrier phones. Always get international phones because they are not locked forever.
I have the international version so I don't know about the bell one. Go to dial pad and input *#*#service#*#*
From there navigate to service info / configuration. Under rooting status, if it states "yes" next to bootloader unlock allowed then you can unlock it if it states "no" then it means no

Thank you for that.
I went through the directions and the bootloader says no. Looks like I'm heading to return it later today as I'm not interested in losing out on features if I was to root etc...
dang, I feel like I was so close to, but after reading on everything for a few hours, I must hang up the towel. I will probably try and buy the Sony Z5 Dual in green now from Ebay (the color I wanted anyways)
Thanks everyone for the assistance even though we came up short!

No worries, at least its not too late to return it. You can still root the device but just can't unlock the bootloader.
Just curious, how much did you pay in total for the phone outright?

$649.99 + tax so $734.48 which I totally didn't mind, I was due for an upgrade and was able to sell off my previous phone...
I'm looking into the Z5 Dual and it's showing me $854 for it... on ebay at least http://www.ebay.ca/itm/Sony-Xperia-...903367?hash=item419df43c47:g:86QAAOSwo0JWF52C

That sucks, sorry you are having difficulty. As an FYI, I made multiple edits on a coupe Xiaomi Qualcomm devices with a NV editor and the changes stuck but it never enabled any additional bands. I see that neither model on the Z5 Compact is compatible with Wind on any band by plugging in values here:

It works but you have to know what you're doing with it. Did you contact Tmobile for unlock code. We unlock and blacklist repair the Sprint, Tmobile, etc. The Tmobile ones have to go through that app during the process

yea man i called...they sent an email with instructions.. email stated this phone doesn't require an unlock code as it has a built in unlock app. follow the directions below blah blah balh
bottom line, it doesn't work. why? because there's hidden rules and crap that need to be met 1st by t-mobile. prepaid people need to spend at least 100 dollars in refills before the phone is eligible. post paid people need to have the phone active on t-mobile for a minimum of 45 days and your account cannot be cancelled during that time.
well seeing as how i'm on prepaid... i walked in, made a new customer purchase as a post paid user, then cancelled my line after i got my gear vr and netflix code... which wasn't even 30 days. I can't unlock my phone, So I'm now on prepaid gonna see if I can after 100 dollars in refills

I use ebay to get my unlock codes, unlocked maybe a dozen phones in the last few years and never had any issues with anyone.
A couple reliable sites I've used many times are www.unlockbase.com and www.cellunlocker.net . There's also a thread over on the s6 general forum of a member named stifilz that can unlock your device via USB cable, his service is free but a donation is always a nice gesture. Good luck!

kinda ridiculous you have to pay to get an unlock code still. My SM-G930FD i bought unlocked locks itself every time in install a T-mobile csc and the app wont even run on that phone
Hi can anyone help? I bought an At&t S7 Edge on amazon and got the unlock code from the vendor and it apparently worked. My only issue is that it'll only work with the sim that was in the phone when I entered the code. If I use another one the phone keeps displaying "insert sim". Thanks already for your replies
Thanks for the reply and there's 1 more things I need to mention: I'm using the phone overseas (Haiti) as it's still under At&t contract. Now to answer your questions no it doesn't ask for the unlock code anymore but like I said it only works with the non At&t
sim I used when entering the unlock code.

s7 (sm-930f) lock to Austrian A1 was not able to be unlocked by unlockbase.com. However, the nck from cellunlocker.net worked well.
Ok so what im mentioning is something im still not getting quite well, but i saw before many samsung phones S6, S7, Note... etc that have the international firmware 9XXF/FD even when the phone is actually a T-Mobile version or AT&T, in download mode you will be shown the real phone model but the firmware isn't. Of course through Odin with a PC you won't be able to flash the phone with a firmware besides the one designed for it. If you actually wanna flash the phone you'll need the original firmware, i tried it before and flashed a Verizon S6 that had the international 6.0 firmware on it through Odin and as you might guess i got an error as the device didn't match the firmware, when i actually flashed it with the correct Verizon 7.0 firmware it worked and the phone booted and worked alright, except that now the phone is network locked! downgrade isn't possible unless i use a repair firmware and a pit file (not sure if still works with nougat). Then i got the idea of actually using the repair firmware and the pit of the 9XXF version as its network free, and ended up breaking the phone completely. The jig didn't work so couldn't access odin. So i work for a friend of mine in a repair workshop PC, Consoles, Mobiles... blablabla and we have the Z3x box, it did unbrick the phone, and then i started playing with it to see what it can do, and there is an option to actually flash and mix different parts of the firmware, so i went an flashed the bootloader of the Verizon firmware with the rest from the international firmware, it didn't boot at first but somehow i got it into recovery mode and after a format it did boot, and the network was actually unlocked after.
I do not think this method would work on all versions, as some samsung phones uses the snapdragon soc while others uses the exynos soc, and i don't think you can mix those firmwares, but an unlocked exynos model might be unlockable with the international firmware, of course considering the risk of breaking the phone, but if you're lucky as i was and have one of those boxes you shouldn't be much afraid.
Something else i'd like to mention, is that the Z3x can actually fully backup the phone, and i don't mean a nandroid backup like TWRP but like a full partitions backup, and the idea i got but didn't test is if you have for example a locked S7 and an unlocked one and same model so let's say 930P, you can actually copy the raw partitions from the unlocked one to the locked one and i don't know, maybe ending up unlocking it too, again didn't test this one as i only have one S7 and its already unlocked (930FD).

Question about unlocking SIM on a BNIB t-mobile s7 for use on Verizon

So like the title says I have a brand new never started/updated t-mobile s7 and I'm looking to use the phone on the Verizon network where I currently have a plan.
I've never unlocked SIMs before so I figured I'd check here first, I don't want to brick the phone obviously..
So my question is how do I go about doing this? I see t-mobile has an app that unblocks the SIM for customers, however I'm not a customer and do not plan on using t-mobile network.
I found some dodgy websites that claim to be able to do it but I'm not sure how I feel about handling over my information to them especially without at least some third party confirmation that the service actually works and is not a scam.
Does anyone have some input on what to do?
Flash the 930U firmware to it. This should allow it to be SIM unlocked.
Try calling tm you just never know they may just give you the unlock codes. I had a phone lock to att once, gave them a ring and they gave me the codes, just be nice.
I used the tmobile unlock app on device. The app checks if you qualify same as a rep would.

So I got the phone unlocked but only to find out the T-Mobile s7 is GSM, Verizon runs on CDMA which is not compatible.
Now that I have it unlocked, would it be possible to flash the Verizon s7 software and have it connect?
I assume I'll need to root the phone in order to do that but will the hardware interact properly with the Verizon software?

CDMA and GSM are two different frequency bands, and use separate hardware. Meaning, they are physically not compatible.

The good news for you is that the S7 sold in the United States all contain the same hardware, the same actual components, so they all physically are capable of handling both GSM and CDMA networks. Also good for you is that now that the phone is unlocked, you can either flash the Verizon firmware or flash the "U" firmware on your device. Normally speaking, this would be really bad advice for any other device, but for the S7 it is possible.
I have the T-Mo S7 flat, and I am running the latest U firmware on AT&T, though I have flashed many and sold them for Verizon.
Don't fret, be happy, and Merry Christmas!
will this allow lte+,in order words can I make a call and still browse the internet on verizon?

Could use some guidance picking the right model.

Hello!
So I've been going through a saga of getting the right phone and even through googling its hard to decipher exactly what i need given my experience.
I'll provide some details and where I'm at or at the bottom i'll give a TLDR.
I live in the US have AT&T and I want a rooted S7.
Got a S7 for xmas, after doing some research found out that model isn't rootable (SM-G930).
Returned it got one I found was rootable SM-G930W8, said unlocked, and I saw on a few resources it was compatible with AT&T.
Rooted the w8 beautifully, got my new sim card and no signal.
Put in #7465625*638*# and said "Carrier Locked"
Worked with an unlock service, they looked up my phone to tell me exactly what it was, have the code on deck.
Enter code, crickets but possible my sim card doesn't work or i need to try on the stock rom.
Got a new new sim card, no signal. Erased my root and went stock data wipe, no signal.
Tried my best to find stock firmware that lined up with the info the unlock company gave, no signal.
Now, given all that information, can anyone recommend me a model? Just want it to be rootable and work with AT&T.
I'd appreciate any comments on my experience too because clearly i messed up somewhere or the phones sim card reader was busted etc.
TL;DR : I'm USA & AT&T. I want an s7 that is rootable. Had an episode with my previous attempts and would love a guru's advice.
The sm-g930w8 is the same model sold by all carriers in Canada.
Does the phone have a clean imei? Sim card works in another phone?

The old s7 has been sent back so I can't really answer that question.
Nor can I answer the sim card works, because i dont have an extra phone that uses that type.
I did go to the AT&T store to ask if they could check my sim card with an extra phone they have.
Apparently they don't have extra phones ready for that type of nature??? (wtf???)
So I got a new sim card activated from them to see if the s7 would take it, it didn't.
Still just sounds carrier unlocked to me, what service were you using to try unlock it?
Otherwise the G930F is the international model and easiest to mod.
Only concern you'd have is the US uses a different network standard to the rest of the world, so your 3G/4G won't work as well on a non-US device.
EDIT: There also seems to be some root methods for the US models:

So to give more details.
I installed the Superman Rom, put the # in to input the carrier code. At the top, in all caps, above the input for the code "CARRIER LOCKED".
Would the superman rom mess with that? or show bad info? not sure
What i do know is that i factory reset the phone, tried the # to get the prompt didn't work.
Tried a few alternatives, same one with the actual network code in it, the 1101, both didn't work.
The company is "Unlock Scope"
Is the imei of the w8 clean?
The w8 should work with at&t when unlocked.

So I'm not 100% sure but..
When I was originally using the unlock service they needed the original carrier information, which I didn't know, so they asked for the IMEI so they could look it up.
They emailed a full list of details on it and I'd think that it would of been flagged in that process, assuming though.
So the w8 is now unlocked through the unlocking service?

Edit:

That is weird because I got one for a friend, got a network unlock code,and it works perfectly on T-Mobile and all carriers in Canada.

Can I root my Samsung S7 and gert rid of "all things ATT"..?

So, I'll apologize if this has already been dealt with previously, but I just need to verify what I've been told by a friend who knows Android systems (and Samsung S7 phones) a LOT more than I will ever attempt to understand..
About a year ago, I bought a Samsung Galaxy S7 from a 'rebuilder' (my term) who mentioned at the time "... it was ATT phone..", and, yes, when I turn it on it does the ATT circle jerk logo and has an ATT logo on the back of the phone. This was of no real concern to me, because my service purveyor uses the ATT system (Consumer Cellular), so it's worked well enough. But unfortunately, it also has a boatload of 'semi-proprietary' ATT trash in the phone which I'd like to get rid of. To confuse the matter even more, it appears that I cannot 'unlock' the phone because it has not been associated with an actual active ATT account for close to two years, and it APPEARS that now they refuse to accommodate an unlock code for this phone.
So... according to my friend (Mr. Android Phone), I can 'root' this phone to 'factory original firmware' and make it (in essence) just a plain-old-vanilla Samsung S7 without this rather bogus ATT firmware and the myriad of craplets I'd like to get rid of..
So, I'm here looking for "expertise" in such things because I certainly don't want to 'brick' this pretty nice phone, but I also want to get this to a point where there is no association with ATT in any manner. So my question sorta comes down to: "can I root this and be rid of all things ATT?", and "will this allow me to achieve an 'unlock' without having to play ATT's games? (I had QUITE the discussion with an ATT 'support' dude a couple of hours ago when he flatly refused to give me an unlock code so I could simply ATTEMPT to see if Consumer Cellular's T-Mobile service might work better at my home, since CC tells me I'm right in the center of a brand new rebuilt 4G service area).
Does any of this make any sense to anyone? Pardon my ignorance, but if the IMEI # is somehow 'tethered' to ATT and they won't "release" it, how does rooting help with this? - or is this something more like an 'association' of the IMEI # AND the ATT firmware...? GAH!! I'd just like to be totally rid of all this ATT junk and have the freedom to choose whichever service I want.

Hi There that's a lot of words partner! I'll try make the answer easy to understand and I've cut out much of the post so my reply isn't huge.
1. Yes you can install vanilla firmware which will remove all branding from AT&T and you don't need to root the phone to do this. here is the firmware for your device >>here<< You can also use XAS or XAA. You will see the guide and the Odin you need to flash this firmware.
2. This is another version of Odin on this website if you have any issues with the one on Sammobile. >>here<<
3. Unfortunately you cannot unlock the phone unless the original cell phone provider gives you their half of the unlock key as a code to input to the phone. In the UK once a phone is out of the initial contract period it is illegal for the provider to refuse to give you this code whether your still with them or not. I know in the USA you guys gets ****ed over. The original account holder of the phone can ask for the unlock code but not you.
4. Changing the firmware and unlocking the phone to any network are two different things, flashing unbranded firmware will not unlock the phone the network is tied to. They don't make it that easy!
5. As far as i know T Mobile (USA) has also moved to G930U firmware so you could be lucky with a T Mobile SIM working once the phone is flashed with this firmware but don't hold your breath. Check Sammobile for the T Mobile firmware too.
6. IMEI number is tied to the phone so in theory it can be changed after the phone is rooted and you are able to modify the EFS partition but it is extremely difficult even for veterans like me and it causes lots of problems with cell network registration. Leave well alone if you don't want a completely useless device.
Things to make flashing go easier
1. Turn off FRP lock or sign out of the Google account on the phone or delete it before you do anything, you can put that account back on the phone after flashing.
2. If you enable Developer options make sure " usb debugging" is enabled and OEM unlock, not essential but can help when things go wrong.
3. Anything you want to keep, pics media etc back up or move to SD card, the SD card won't be touched when flashing firmware.
4. Please follow the guides on how to flash correctly.
Any other questions please ask.
It should be noted that if it's an ATT phone it's Snapdragon therefore permanently bootloader locked, OEM Unlock won't actually do anything, that setting only works on Exynos.
The only root method for Snapdragon is to use a leaked engineering bootloader to gain system access, and you can only install the leaked bootloader if your phone is already running old firmware. For up to date phones there is no root method.

Don't be smart you know how to use Google?
I did google it, I wouldn't have asked for a source if I found something. But it doesn't matter, you're the one making unsubstantiated claims, the burden is on you to prove it. But since you asked for it:
AT&T's website says Snapdragon

GSM Arena says Snapdragon

Wikipedia says Snapdragon
https://en.wikipedia.org/wiki/Samsung_Galaxy_S7#Qualcomm_Snapdragon_820_Models
There isn't a single page when googling AT&T S7 Exynos that backs your claim up. The USA also uses completely different network technology than internationally, using the S7 Exynos in the USA is already known to cause issues with LTE, VoWiFi etc. They'd have to do a hardware refresh of the Exynos SoC if they wanted to support it in the USA, which they ain't going to do a for a 3 gen old phone.
