[Q] Updating Question - Moto X Q&A

Dear All,
I have recently bought a used Moto X (AT&T) unlocked. Current system version is 140.44.5.ghost_att.ATT.en.US. My question is will updating cause it to carrier lock again??. Because it has downloaded an update and it keeps notifying. The downloaded update version 165.44.1.en.US. I am afraid if i update my sim won't work. So anybody has experience regarding this.
Thanks

I haven't applied any hack yet. I bought it used "unlocked". It has an AT&T logo on the back so it was locked to AT&T before. Now if i perform an OTA update.. will it get sim locked again. I do not mean or care for root. Just my sim should work. I hope i have explained well.

So, I went on and performed the OTA update anyways and its all good. The sim still works. The phone did not lock again.

good deal!

Once it is carrier unlocked, it will always be that way.

Sir to make this clear for you let me guide you through what sim unlock is: A Sim Unlock is performed over Cellular networks.. It does not have any I repeat ANY concern with the software of your mobile phone. When you unlock your sim through an unlock code the IMEI of your phone gets registered over Cellular networks so in easy words The unlock happens in air not on your phone. So whatever you do with your phone you will never ever be sim locked again because the IMEI of your phone has been registered permanently on the network when you unlocked the sim before. So feel free to do any kind of thing on your phone dont hesitate .

Carrier unlock a G920T permanently

Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Code:
SW REV. CHECK FAIL DEVICE: 5 BINARY: 3

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help

BAD ESN IMEI Droid Turbo

hello
i've bought a droid turbo from amazon.com
and after i received it
it did not detect any sim card
i've contact the seller he told me the imei was black listed in USA and im using it in Libya
so if i rooted the device and installed a Custom ROM
Will that let the SIM Card Work ?
cuz the device is still on verizon stock
thank u​
What version firmware does it have?
You can only bootloader unlock and root Droid Turbo XT1254 on SUTL-44 firmware -- or lower, which can be updated to SUTL-44. Any higher, like SUTL-49, cannot be bootloader unlocked and rooted.
It shouldn't be blacklisted in Libya, but it could be.
Have you tried going into network settings and changing the mode to gsm?
also, dial *#*#4636#*#* and see if you can set it to LTE/GSM global under that menu
I think even with bad esn phone will work with sim card outside usa
You should t have problems with original firmware

Well, you can never unlock the bootloader, root and install a custom ROM.
SUTL-49 was released specifically to block the SUTL-44 Sunshine bootloader unlock exploit.

Could it be hardware related?
http://removeandreplace.com/2013/05/30/what-to-do-if-sim-card-in-phone-is-not-recognized-or-reading/
i think it´s hardware related
is there anyway to make sure it's a hardware issue ?
can be fixed or no
it always should detect sim card, even its esn blacklisted or not, i think

See the article I linked about cleaning the contact wires. Also try a different SIM card, just to see if it makes a difference.

Firmware question

Hello, guys! I`m using my s6 at&t in Ukraine, and it works perfectly with my sim. Firmware is 5.1.1 Is it possible to install 6.x and it is possible to get my phone locked to at&t after installin it? thanks in advance
I doubt that if your phone is a unlocked phone also known as a sim unlock phone that is that it can be used with any carrier would get locked due to a software update. Since you mentioned that you are in Ukraine and if it works with the local sim that means that the phone is a sim unlocked phone and would probably not be affected by a software update.
Also just use odin to update the phone

TWRP and ROMs for Note N920A w/ Nougat

Can I install TWRP for the AT&T version with Nougat? I have heard that if I try it will brick. I'd really like to install a new ROM so I can get rid of all the crapware that comes with the phone.

The 920A At&t cant be rooted as of yet and no twrp because the bootloader is locked...
Bootloader
I recently talked to at&t about getting my bootloader unlocked and a supervisor told me the only way to do so without bricking would be to being it in to an at&t store and they will unlock the bootloader.. anybody else have this told to them?
They're most likely taking about a Sim unlock not bootloader. Also there is a method for rooting it but you have to be on a specific bootloader and you can only use it on lolipop.

Ya, I know about that root method. Unfortunately, my phone decided to update itself a few weeks ago and now its on BL 5. So that's pretty much a no go.
In relation to bringing in the store for a BL unlock, I did specifically ask and made sure the tech I was speaking with knew the difference between BL and sim unlock. In fact, i made it very known that my radio was already unlocked, I done that weeks before i talked to her.

Question about SM-960U and firmware flash/ carrier change

I recently purchased a supposedly unlocked note 9. The back of the phone reads SM-960U which appears to be the factory unlocked model. It seems to be locked to sprint because anytime I try to flash over to a Verizon firmware it is successful but still reads BST/BST/SPR in the software menus. Do I need to find a way to unlock the sim from sprint or am I missing something? Thanks in advance.
i have the same problem, but in unlocked t-mobile. mine is now XAA/XAA/TMB. works like a charm so.......
