So, I have an Xperia Play that I only use for games. I don't use it as a phone so it is not activated with any carrier. It is a verizon model so the bootloader is locked.
Since I don't intent to use the mobile network, am I cool to install GSM roms if I want? Can I do something about the bootloader? Can I transform it into an ATT model with the unlocked bootloader or anything like that?
Lol transform it into an ATT model? You're kidding right? But yeah, you're cool to install GSM roms as long as your bootloader is unlocked
You can't transform the phone from CDMA to GSM since they require fully different chipsets. However, provided that you unlock tour bootloader, you can flash GSM roms at your leisure.

I think I can get a T-Mobile S5 and a SIM unlock and use it on AT&Ts network. Is this correct? I really want an unlocked bootloader and the abilty to run non touchwiz roms. Also, is it possible to create a hybrid kernel gto support AOSP roms under touchwiz. Never mind, locked boot loader can't change the kernel anyway, can I?
The other option may be the verizon dev edition phone. Is it possible to unlock it for ATT Network use? I'm a developer myself but just into android and cell phones in general, and I do not yet know what parts fit togrther

The T-Mobile S5 is capable of being unlocked and used on at&t's network.
I use a T-Mobile variant on AT&T and love it.
All the required bands, excellent speeds and plenty of ROM options.
Unlock G900A

I have an ATT SM-G900A S5 that is locked. I have the unlock code but don't know how to enter it. I have an old T-Mobile Sim but it is deactivated so it wont trigger the unlock fields. is there a code( *#xxx#) I can use to allow me to enter the unlock code?
Do I have to find an active T-Mobile sim?
Thanks for the advise. I just got this S5 and can do all but use it as a hot spot! ugh HELP!

First of all don't just randomly post in other peoples threads. Do you have a question? Thoroughly use the site's search function and search google. If, and only if, you haven't found your answer you start your own thread (not just randomly post in other peoples threads).
As far as I know you need a working sim card of another operator. I'm sure you can order them for free online.
Don't post in this thread no more. Make your own instead.
Here is a really good start for you. Good luck. :good:
Hi,
Tomorrow, I will be paying a visit to the US Cellular store so that they can unlock my phone for use on GSM networks. I usually run the unofficial build of CyanogenMod 12.1. But I learned that in order for them to unlock it I must be on stock. My question is: after I get it unlocked, will I be able to flash back to my backup of CyanogenMod without relocking the phone? I know on full GSM phones it's more of a hardware thing. But I want to be sure once it's unlocked that it's permanent.
(Also, I forgot to mention it's the US Cellular variant of the Galaxy S5)
Thank you!!
ROMs don't affect SIM lock afaik, or you'd be able to unlock them with a custom ROM too
Hello. I have been on the forum for days searching for answers for the sprint variant, which is hard to find solid proof of it working completely on gsm. Now for the verizon variant. If I buy a verizon variant will it work fully on GSM carriers like at&t?
Plus can it be fully converted? Including radio, to the US unlocked version? I have done it in the past with the at&t m8, converting it to unlocked variant with s-off, cid change, and ruu. I see tutorials saying to flash unlocked version to then reflash verizon radio. Will it work with unlocked radio? Or is it the same as with the sprint variant, where it always needs sprint radio?
Thanks for any help.

Thanks. I had read that forum, but since the guide posted says to flash verizon radio, I was wondering if you could leave the unlocked radio. After reading various posts afterwards it seems it is posible to not flash the verizon radio (keep the unlocked radio).

Correct, you can fully convert to Unlocked without flashing anything Verizon afterwards. Im using my Vzw 10 on a gsm network, converted to unlocked.

Thanks. I will look into buying the verizon variant. Did you also have to sim unlock? Or will flashing the unlocked version ruu take care of that? I truely doubt it, but I can not find any verizon unlocking service. And the only 10's I can find are locked to verizon.

Verizon 10 is not sim locked. You can take it, in stock Verizon form, and insert a gsm sim card and it will work. The real benefit of converting to unlocked is to have direct updates, have access to more lte bands, and best of all not have Verizon's bloated OS.
I have a question. If I bought this phone outright, and sprint basically locked rooting it via boot loader version 5+, could another carrier flash it with "something special" to get it on the carriers firmware? If I own this, and Sprint locked a feature on me, wouldn't that make them liable for damages?

Not really. You bought the phone to use specially on Sprint as a Sprint phone. When it came out, no one knew about the u firmware or using it on other carriers. There is a post on here about unlocking additional lte bands. If the phone is carrier unlocked, you will get some service on all carriers, but not all the bands will be unlocked.
I obtained an XT1766 (Qualcomm) with build NCQS26.69-64-11 from an mvno called Tello (aka Sprint). The state that all the phones they sell are unlocked. The SIM say Sprint on it. When I asked if I could use it on a GSM carrier they said it is only CDMA compatible.
The XT1766 spec clearly shows it is GSM capable, and Sprint themselves state that they can unlock the phone for at least international GSM, and US GSM after a set amount of time.
I installed a GSM SIM, and the phone report "Hidden Menu" Invalid SIM.
My questions:
1) Is Tello in denial that the SIM is unlocked? It seems GSM locked to me.
2) Does this phone have an Android build created by Motorola that disables GSM?
3) Is the only way to enable GSM is to unlock the bootloader and install custom OS?
4) If the phone is "locked", the Motorola will not give a key to unlock the bootloader. Correct?
5) Can this CDMA sprint based phone be used for other CDMA carriers such as verizon?
Sorry for all the questions. I am new to how these things operate.

Can't use it on gsm anymore. The new update locked it up tight. You can still unlock the bootloader. But custom ROMs aren't going to help. They closed that hole right up.
What is the build number that locked up the GSM function?

Either -08 or -10 were the end numbers of the build that did it. Can't go back either. It set an efuse. No amount of downgrading can undo it. It's been tried. To the point of bricks. Sorry bro.
No longer works for domestic unlock if you have late 2018/2019 security updates. You can only unlock it for foreign use

AFAIK no foreign either. Feb 2019 wont lock the device to sprint but it wont unlock you with C.Roms. Jun 2019 will lock the device and no way to unlock it to be used either in the US or outside. Just Sprint by now.
Again... As far as i know. Correct me if i'm wrong please.
