[Q] Verizon firmware with modded frequency bands? - Xperia Play General

Since I like stock android better than SE skinned version. Is there a way to get mod Verizon's stock android firmware to get different frequency bands like AT&T/Rogers
http://davinciteam.ca/ software allows custom firmwares. I wouldn't mind paying $15 if it gets me my stock.

I have the same question as well. just the other way around. Can we get uk firmware to work on us verizon xperia play?

U.S. SM-P605 Finally!!!

http://www.sammobile.com/2014/01/10/verizons-galaxy-note-10-1-2014-edition-sm-p605v-visits-the-fcc/
I have been waiting for the U.S. to get the LTE version of this tablet and it looks like the wait is almost over. I still prefer a GSM version, from T-Mobile or AT&T. Carriers have been known to modify devices, so I am hoping they added USB 3.0 and changed the button layout similar to the Pro series with Kit Kat. That's wishful thinking but the reality is all we may get is a locked bootloader and Verizon logos!

It's a P-605 so it'll be just like all the other P-605's. With the N3, all the U.S. carrier versions had the same h/w (except specific radios) and feature sets. Except of course what each carrier added and took away via s/w modifications. The "V" appended to the model number means VZW's N10.1-14 will probably follow suit. I don't know if you care, but all the U.S. carriers disable MMS and the dialer on their 3/4G tablets because they don't want them used as phones.
Not too concerned about SMS and call features, LTE frequency compatibility to make use of data is my main concern about not getting the non-U.S. version. I think it was AT&T who made hardware variation to the LG G2 buttons, so maybe useful mods can be made for the P605.

[Q] Installing a stock rom on a verizon UNLOCKED s5

Hi everyone!
So during my trip in the US, I decided to buy a brand new Galaxy S5. I was going to use it outside US so I wanted an unlocked version (since they don't sell international versions in us)
So I got a verizon version of the S5.
Model: SM-G900V
The problem
The problem is that i am getting notifications like. Non Verizon sim inserted. Loads of verizon bloatware. and I cant use my mobile hotspot. Similar to this
I absolutely hate this. I paid $800 for this phone and I'm bombarded with verizon's nonsense and restricted for no reason
My question
The question is, can I install a stock rom on my S5? more specifically can I flash the SM-G900f ?? So that I can get rid of this custom verizon software.

Well it's complicated and you have some reading to do if you really want to understand your options. But broadly speaking, the answer is yes. Since you were (or are?) planning to use the phone elsewhere, you'd have been happier had you bought a different S5 variant e.g. a TMobile S5 rather than the Verizon one because you would find it a lot less restrictive, give you more choices and options. And even access to a larger palette of frequency bands should you end up roaming somewhere that uses unusual frequency bands.
Note that there is a dedicated Verizon S5 forum here where you'll find most of what you are looking for. What you are thinking of as a stock ROM would be more accurately called a custom ROM. A stock ROM is.. well what you currently have, with all of the included carrier /Verizon applications that are annoying you. You'll probably want to root your phone and flash a custom ROM to get rid of a lot of superfluous Verizon stuff. That may have warranty implications and you should do some reading about warranty and locked bootloaders (something extra nice that Verizon and ATT do to make it harder to flash your phone).

Turning At&t priv into non carrier bounded priv

Anyone know how to replace At&t atrocious Priv firmware with a regular blackberry firmware, one not modified by any carrier. Mine has issues with MMS which At&t has still not sent a fix update for, and marshmallow deployment is unacceptably slow considering all they are delaying it months for is to ensure junk like at&t nav or their other bloatware works, especially since once android N comes having the touchpad and keyboard will make multitasking a dream (if At&t even releases n when it comes out).
it cannot be unbranded or debranded, you can freeze bloatware and install alternate apps for your device, it is what it is, on samsung devices you can do it.. even with stock software

Want to move from Sprint to T-Mobile... too much info, need short answer

I'm kind of newb at this S7 stuff, I'm more of an HTC guy. Yesterday, I bought an unlocked G930P (sprint) and am not sure, but think I learned that normally, people don't change out the ROMs to use a different carrier, they simply unlock the phone and live with the old carrier's bloatware. I started reading up, and first learned that TWRP apparently isn't available on a Snapdragon processor, so the G930A, G930P, etc, aren't candidates for TWRP. At first, I was kind of dismayed. Then, I found the G930U ROM and on a whim, I tried punting the G930U ROM to the G930P. I bought the phone off craigslist, and he said he didn't know where HE got it from, but it was unlocked. Anyhow, the phone took the rom without a hitch and now it looks like a U model...
My goal: Go with T-Mobile. Use Wi-Fi calling. Eventually have Nougat. Remove bloatware, but possibly keep some nice T-Mobile add-ons, if any, because I don't have their service yet (I hated ATT's crapload of stuff). Note this isn't specifically a "TMobile" question, substitute your carrier of choice for the questions...
Get to the damned question, you say? Ok, here goes:
1. I'm not going to ask any "do these bands work" when moving from a P model to T mobile. You guys seem to fight about that stuff until you can't type any longer. I'm going to assume what whatever bands work, that's what I get. Unless I get a T-Mobile specific phone.
2. But I will ask this: do the over the air bands it uses depend on the baseband ROM that is on the device? This is something I can't figure out.
3. I heard T-Mobile uses an updated boot kernel (3.0?) and ATT & others use an older boot kernel, and that if I move to T-Mobile boot kernel, I can't go back to any of the older ones. This process I seriously don't understand. Can I run a T-Mobile OS (or any OS) while using an older boot kernel ROM? I would think NO, right?
4. I don't like all of Carrier X's bloatware. I'd rather use a stripped down, cleaner ROM. I guess there are apps for that, but is it cleaner to do it with a stripped down generic ROM that I see floating around?
6. Speaking of ROM's - I saw a lot of Xetheros or whatever ROM's floating around, but it seems like there aren't any for the snapdragon-based ones. Is this true? The posts on this site don't really talk much about the snapdragon-based phones and why there aren't any ROMs for them, and why it won't work, and what, if anything, is being done to get around this. I guess the G930U is Samsung's answer to that, and allows fooling around with roms, but will the other phones ever be actually rom-able, or should I ditch this G930P and actually buy a G930U? Now that my phone THINKS it's a G930U, did that get me around some weird barrier and NOW I can update other funky roms intended for a G930U?
I'm considering selling the G7 I just got and going from a G930F (now that I'm a bit wiser). Any common sense why not to do that? I already HAVE an ATT G7 (not the sprint one I just bought), but it has a "bad signal". It gets only about 1 bar indoors, on a good day. I took it to a repair facility and they said, "nothing wrong with the antenna, it's your mainboard, don't bother just buy a new phone". Anybody have any advice on that?
thanks

All U.S. models are built the exact same and will all accept each others firmware if done right , so any unlocked s7 you put the U firmware will essentially be a g930u other than the number stamped on the back , I dont believe the U firmware supports wifi calling or VOLTE , There is a t-mobile nougat firmware floating around if you want to try that , your att g7 if it has a hardware issue should be under warranty but if your using it with a different carrier I would flash the appropriate firmware to it and see if that fixes you signal issue and if not put it back to stock and call Samsung , as far as switching from the international model , Well i bought a international edge as soon as they release and it took a crap on me within 4 months and I was unable to warranty it , that was my only issue with using a international model but also i dont think you can get wifi calling on those either . hope that helps
edit* and yes the bands are dictated by the rom , U firmware opens all of them otherwise carrier roms unlock specific , and T-mobile nougat dowgrade back to MM will be dictated by the baseband , I know the Sprint nougat can be downgraded but not T-mobile for sure

The U firmware does support WiFi calling and VoLTE on T-Mobile.

I guess us AT&T users just done get them features =/ , is it enabled or do you have to do something to enable those features ?

I don't believe those features are supported on AT&T (probably at AT&T's own request). Perhaps that might change in the Nougat version but I wouldn't bet on it.

What are the advantages and disadvantages of Verizon S7 vs. Unlocked S7?

Hello everyone,
I am looking to upgrade from my S4 to an S7 over the next few days, and I have been trying to decide which is the better option between the Verizon model and the unlocked model. I will be using this phone on a Verizon network for now, and was leaning to the unlocked model to get rid of the Verizon bloatware. There is a chance I will be living in a different country in another year or so, so I figured the unlocked model would also give me more flexibility with my next carrier, as I had heard the Verizon model does not support all carrier frequencies. Are there any distinct advantages to going with the Verizon model over the unlocked model, or are there any other important differences I'm overlooking between these two options?
Thanks!
Unlocked how? Boot loader unlocked or carrier network (SIMM) unlocked? Verizon phones are carrier unlocked. Meaning, you can already take an AT&T SIMM and put it into the Verizon S7 and it will work.
As for removing verizon bloatware, that's only possible if you root. Unlocked is specific to the carrier only, not an unlocked bootloader. None have an unlocked bootloader that I know of.
The carrier unlocked phones also receive updates much slower than the normal ones.
https://plus.google.com/+DroidLife/posts/ENv2fH9zD7e
If you want carrier unlocked phones that get updates faster than the generic carrier unlocked phones, get the Verizon phone. As per this article, it's already carrier unlocked and it's already updated to Nougat. Might be some hoops to jump through, but it works:
http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked
The generic unlocked ones are still on Marshmallow and there is no word on if/when they'll get Nougat. Also, the Verizon one is cheaper than the generic carrier unlocked phones. Expecially if you can find a sale going on for it.
There is a hybrid rom that is debloated and works great for all models, it is posted in the vzw amd tmo s7 forums. I'm using it on two phones myself.
The U firmware has no bloat, and has all bands available for use. The main downside is that nougat still isn't out for it, and certain apps won't work if you're from Verizon such as their voicemail app.
On the plus side you get some features that Verizon charges extra for, such as caller ID built in for free.
Regardless you can flash any firmware to any S7 so long as it's the snapdragon variant.

I've been curious about the G-930U also. If you know, please tell me if these working assumptions are correct or not: The "U" has no carrier branding on it and it has no carrier "bloat" in it (although maybe some Samsung stuff). The "U" CANNOT be bootloader unlocked because it has the Snapdragon processor and at present none of the Snapdragon variations can have their bootloaders unlocked (how I hope this isn't true!). The "U" can be flashed to carrier-specific firmware, although I don't know what the advantage would be.
I'm still mostly using an XT1575, the Motorola X Play Edition 2015. It too had no carrier contamination but it's bootloader was easy to unlock. All I had to do to get it to work with Verizon was insert my nano SIM card. Do any phones still work like that?
