Is it safe to update/flash unlocked firmware after unlock? - Sprint Samsung Galaxy S7 Edge Questions & Answers

Just got my phone unlocked and was wondering if I could update or flash the G935U firmware. Don't wanna waste the $10 I spent on it

How was it unlocked?

By a service on ebay.

Was it remote access by USB cable then Factory unlocked? If so then you safe to flash any unlocked 935U. If your not with Sprint or any major US carrier best one to flash is the XAA.

It was remote accessed by USB. And I'm on AT&T.

If you go to a U Rom the downside you might lose your band 30 and the carrier aggression. AT&T doesn't have a Unlocked rom. So you would have to use XAA 935U which is a universal American unlocked ROM. AT&T uses band 30 pentrate inside buildings where band 17, 2, 4 and 5 can't get. But that's the only downside being unlocked with AT&T.

But can I update once the Nougat firmware comes out?

The latest firmware right now, but I'm having WiFi issues and I'm wondering if I should reflash the firmware.

If it's the 935U you will be automatically have an update. You probably get that sometime later this month or next month. Since they only do quarterly updates. I think carriers in the US should start seeing Nougat next week. I'm on a Tmobile rom for that reason and to have other features that the unlocked rom doesn't have on it.

I'm on the 935P, and I wanna keep my data this time, I've reset this device thousands of times after failed roots and firmware changing, so I'm just gonna wait until Sprint updates it.

Stock is the way to go, faster updates and better modems. I have heard Sprint releasing 3 carrier aggression update yesterday for faster speeds. I don't think it's rolled out yet might be coming with Nougat this month.

Will my phone work if I upgrade to Android5.0 but my carrier is still at 4.X?

Basically, my carrier hasn't rolled out the updates yet. Is it OK if my OS is on a newer version?

No.
Not sure why the 'no' reply. Mind you that might refer to a locked phone. But if your phone isn't locked there's no reason your carrier would care or know.
e.g. I was on Telstra and was on kk b4 they released jb for their phones.

Nothing, it actually seemed to brick because of a battery issue
Update on this, apparently there is a way to get back to at&t firmware from t-mobile http://forum.xda-developers.com/tmobile-s7-edge/help/yes-downgrade-apg1-to-apd8-t3450382 I personally don't want to try this, but someone else is welcome to.
@nugzo check that out if you want. I'm enjoying the august update from at&t but avoiding root because I kept soft bricking lol

SM-G955U1 Oreo Update Out

I just received my Oreo update for my Unlocked S8+. Has anyone else received it yet? I'm thinking since we have Safestrap and now custom rom support that I'll cancel the update and wait for an AOSP rom.

I was on T-Mobile but switched to MetroPCS two days ago. (Same network)
It's true... I am on Sprint with G995U1 and I am currently downloading a 1354.14MB update.
I had to check for it, but it found it and downloaded it. My phone is unlocked. Update applied without issues.
Loving finally having the auto fill API.
Just checked my software updates for the first time in weeks and there it was! Unfortunately they're working on our electrical system, so I won't be able to download it until WiFi is back up, but it'll give me time to back things up.
Factory unlocked running on T-Mobile
Can anyone confirm if Hotspot remains functional after the update without carrier involvement.

I used the hotspot yesterday at a clients and I also just switched carriers a few days ago and the hotspot worked fine. I did end up taking the OTA to Oreo.
I live in albania and no update, I have the unlocked firmware running in vodafone network. Currently im on BRB1? Any ideas why I dont have an update yet? Thanks

Switch to the U firmware. AT&T firmware won't update without a valid AT&T SIM.

Has 1000% to do with the firmware. Has everything to do with the bootloader. The bootloader is locked and cannot be unlocked so perm root is unattainable on the 935A or U firmware.

SM-G975U1 compatible One UI 2 beta update

Does anyone have an ODIN compatible update for the One UI 2 beta that would work for the US factory unlocked S10+ (SM-G975U1)? I saw a T-Mobile only update.zip, but that only works on T-Mobile locked ones.

It appears the aren't releasing it for U1 yet. As long as your csc is part of the OYN multi-csc then you can use U firmware and use the update.zip on here.

Not familiar with the term "OYN multi-csc", however I can and have flashed different carrier ODIN packages onto my US Unlocked S10+. I assume that means mine is apart of the multi-csc. Mine is "VZW/VZW/XAA", a factory unlocked s10+ bought from Samsung's website with a Verizon SIM in it.

If I'm currently on G975U1ES2BSIE, I assume I can't just flash that update.zip file because it says you must be coming from BSI4. Is it safe to ODIN flash the BSI4 version and then recovery flash the update.zip? Also, in a screenshot on the update.zip thread, it said the source version was G975USQS2BSI4, yet the firmware I have been using has always started with G975U1..., so can I even use the update.zip at all?

You would have to flash BSI4 U firmware via odin first then update zip after full boot. U1 beta has been delayed now untill who knows when. So basically we're stuck with bloat if we want the beta until further notice.

Thank you for reminding me about the bloat from U firmware.... ewww.... Will definitely hold out until more information about the U1 beta comes out, especially considering that someone will likely release the update.zip for it, rendering their limited beta unlimited.
I'm curious about this as well. Didn't the release the u1 beta yesterday? If so does anyone have the update.zip we could apply locally?

I'm on BSIC (thought that was the latest U1 version)
I was on BSIE and had to downgrade to BSIC in order to take the beta update. Even though I registered, wasn't sending it and as soon as I downgraded back to BSIC the beta update came through.

Hmm so I'm not able to grab it while on BSIC; any chance you have the update.zip file
I have the U1 (512 unlocked Snapdragon). I flashed the T-Mobile U image (downloaded using Frija, then flashed with Odin), and then saved the ota zip to an SD card and flashed that update via recovery. Haven't had any issues, yet. While I'm not a fan of the T-Mobile boot screen and default ringtone, the only bloat I've identified is the Name ID, T-Mobile, and Visual Voicemail apps, which all appear to be uninstallable. It also added the video call function to my dialer, which I'll probably never use but it's neat that it exists...
I say all that because you could just install the T-Mo firmware to your VZW phone and get away with a updating to the beta and uninstalling the bloatware, if you're ok with having the T-Mobile boot screen (ideally, you won't see it much anyways).
Just a thought.

Let me get home tonight and I'll extract it
The U1 version of the oneui 2.0 beta was released yesterday and apparently still being released for many users hopefully someone has the logics to make the update zip out of it and pass it along. Not everyone wants to go through completely wiping their phone and swapping unlocked firmware for a carrier one just to test the beta.

That's not how it works. You won't have tmobile bloat. The firmwares now are all inclusive so it will install bloat depending on your installed sim card. Example, I installed it on my AT&T S10+ and got AT&T bloat. If you install on your tmobile S10, you'll have tmobile bloat.

Assuming that's the case, why not just do the entire install and setup without a SIM, then plug the SIM in after it's complete?
I used that trick on the VZW Pixel and Pixel 2 and was able to avoid them force-locking the bootloader.

Between here and Reddit it's been asked several times if that works and there hasn't been a real answer yet. Yes though, that is the case. It's been that way since one of the major updates on the S8 firmware back when it was still a flagship. The bloat and carrier files it installs are carrier dependent. That's why the total download size of firmware went way up.

Im thinking thats why I wasn't ever able to join the beta. Downloading BSIC now and hopefully installing that will make it possible to officially join the U1 beta. After going back to U firmware i remember all the things that made me switch back to U1 last time lol.

Why are there separate S10+ firmware downloads for AT&T, Sprint, T-Mobile and Verizon which have different Home_CSC partitions if the Samsung firmware works like you say? Shouldn't all the Samsung S10+ firmware be U1 (the firmware that comes installed on the carrier free version of the S10+) if the carrier bloat is installed via the inserted SIM?
