[Q] Focus re-locked to AT&T after NoDo Update - Focus General

I unlocked my Focus back in December through NCKZone. Installed the Feb and March updates without a hitch. Now my phone is locked again to AT&T, when I try enterning the unlock code I got from NCKZone I get an error message that says SIM Error. Also, if I try to access the SIM through Phone Settings, it says the SIM is locked. I never had a lock on the SIM card, so I tried the default of 1111 to no avail. Only way to have access to the SIM is after a soft reset. Weird thing is phone is now locked to AT&T, and whenever I try the unlock code from NCKZone, I get a SIM error and it locks the SIM....anyone else experience this? Yesterday I called AT&T, they were useless, they also transferred me to Samsung and all they could suggest is a hard reset.......
I called AT&T this morning, this time the person said the subsidy unlock code changed and they can't give it to me until May 9th, sounds fishy to me. Any one else have this problem?

May 9 is about right date from all the responses from AT&T so far. Officially, AT&T won't give you the unlock code until 10-month after the release of exclusive phones (seems all new phones are exclusive phones now).
But this is the first time that I saw unlock code changes after a firmware update.

did you install the official at&t Nodo? or did you do it with the VPN trick and only install the Samsung specific update?

Me too, hard to believe the subsidy unlock codes would change due to a firmware update, I've never heard of that before. It would be great if someone could confirm if they are experiencing the same thing with the official update and had their phone subsidy unlocked prior to Nodo.

I 'unbranded' my phone before applying the update, and am still carrier unlocked.

Unlocked my phone months ago using code from my longtime friend at Samsung. Phone was just updated, turned on and off a few times including battery removal and still is unlocked. Please do not ask me to get codes for your phone, my friend does me favors and do not want to abuse that.

Hi.
Unlocked one Samsung Focus today with the official NoDo update from ATT, and still unlocked and working fine in Costa Rica, I can still make calls, text sms, mobile internet, etc.

I ended up doing a hard reset and now it is fine, go figure. I now see ATT and AT&T using the Samsung Network Profile tool. Doing this from Connecticut.

So the Samsung dude was right after all. Lol

[Q] SIM Locked after WP7 update ?

hey,
when I purchased the Samsung Focus phone,
it had SIM Lock on it , which I unlocked by
using the UNLOCK PIN ..
want to know if it will get re-locked after WP7 Update . . .
Thanks !
If you got the unlock code once, I would think it would be able to unlocked again if the update relocked you.
I've been watching a few blogs on the update topics, I have not seen anything about sim-relocking yet.
But keep in mind, it seems that not that many people have been sim unlocked, you might be in the minority of Samsung Focus users!
If you do the update, let us know your results.
if you are talking the network unlock...no updates wont re lock it. unless you put the correct diag code then enter the unlock code it wont re lock.... now sim lock is different that is a code that locks the use of a sim card unless a 4 digit code is entered... if you disabled it, it wont come back unless you enable it again...
The unlock codes are not as hard to come by anymore. Lots of different websites and people even on ebay. I used Fastgsm but if it re-locks. oh well. Doubt it will though from what other users have said of other phones
I unlocked the phone using the code from ebay NCK ZONE ...
since NODO is out, wanna know if installing NODO will re-lock my phone...

Hi pal, it will not.

Installed nodo yesterday.
Still sim unlocked.
By chance can you tell me if you are getting a Roaming Triangle?
Do you have a focus from Rogers (paid to have it unlocked) using it with another provider?
Thx

Verizon updating unlocked device with another carrier Need Help

August 2016 while travelling i asked for an unlocked S7 edge from Bestbuy and they gave me the Verizon version. The salesperson inserted the AT&T sim that i was using at the time and all working fine.
i returned to South Africa in September and inserted my Vodacom sim from South Africa and still working fine, even now as i'm typing.
But what caught me is that i have not gotten any notification for updates since i got the phone, and when i go in to 'settings' and 'check for new system update, i get the message: "Software update is temporarily unavailable".
i'm not sure if there were no any official updates from Verizon since i bought the phone or because i'm using another carrier's sim card that's why it's not picking up any updates.
Any help?
Haven't looked into Rooting as i'm not really a power user, but just want to get the latest updates.
Is there a way for me to update to the latest without Root
my current S7 edge's software info as below:
Model Number: SM-G935V
Android Version: 6.0.1
Android Security Patch Level: May 1, 2016
Baseband Version: G935VVRU2APD2
Any input will be appreciated
*sorry if there is already a thread on this topic as i wasn't able to search and find the exact problem i'm facing
Well if trying to update the phone through settings didn't work, I recommend you installing Smart Switch in your pc and updating your phone through that Samsung software.
You got to have a working verizon sim card and service to get ota updates.. Otherwise you'll have to use Verizon update assistant or Samsung switch

thanks for the replies, will take a look at smart switch.
also, if i
1) after update the software, will the device go back to it's locked status
2) factory reset, will the device go back to it's locked status
or does it mean that the verizon unlocked devices are 'forever' unlocked no matter what i do to it
Verizon phones are always unlocked even if factory reset or update

QJ3 updated bootloader

QJ3 <stock sprint> updated the bootloader from v4 to v5. Just a heads up for those of you wanting to flash the U firmware and getting errors.
So, probably a dumb question, but what do I need to do to avoid the errors? I messed up trying to flash a T-Mobile rom right after updating the firmware, and now I can't boot. I can get to download mode, but can't find a firmware that will flash without failing.
From what reading I've done, I need to find a newer firmware than the one that was on my phone originally, but I can't seem to find anything that will work.

You should be able to flash QJ3 or maybe the latest tmob one. Check sammobile or updato... Just checked, not posted yet. Have you tried a Google search for the qj3 firmware?

Thank you, I wasn't sure what the latest version is so that helps. I did try flashing the latest T-Mo and Sprint firmwares on both Sammobile and updato.com, but it looks like neither are newer than QJ3 so I guess that's my problem. I'll just search or wait to find a new version posted. This phone isn't a daily driver so it's not critical right now.

Has anyone tried going to the u firmware via pit file? I remember this working in the past. You have to flash the version pit file and previous stock rom, then you could flash the u rom.

Maybe. About a year ago, you could load a PIT file. Not sure if that method works with the newest bootloader. @spamforme mentioned something about it a few posts ago.

Right now there is no way to downgrade to install the U version software. Sprint upgraded to the version 5 bootloader and is the only carrier in the US to do so, so you can't install any other carrier software on your S7 or S7 Edge right now once you have Sprint software installed on it. I have a SM-G930U I took to sprint this past July under the 1 year free service before taxes promotion. Fully unlocked version I purchased online, after having trouble installing a Sprint sim, I had to go in to the store to get the phone to activate.
Once activated Sprint sim locked my unlocked phone(found this out 2 months later when I tried to put another sim in it.) At this point it was still running the SM-G930U Unlocked firmware. I escalated a sim unlock request in September, 2 months pasted and they still didn't unlock my phone. I ended up having to go back in to a Sprint Store to facilitate the unlock, and during that process the Sprint store, flashed my phone to 5BQJ3, that being said, after they did that to unlock my phone they were unable to put the Unlocked firmware back on the phone in the store, I have failed to put the unlocked firmware back on my phone since also, I have escalated this to Samsung, as my phone is under warranty and Samsung say there is nothing they can do. So Sprint sim locked my unlocked phone, and during the process of getting my sim unlocked phone back unlocked, they hijacked my phones software and put all the sprint bloatware and malware on my S7 SM-G930U unlocked phone, and it can't be removed currently as Sprint is the only carrier using bootloader 5 in the US.
I ended up filling out a complaint with the FCC about this last week, and waiting for Sprint to respond as the FCC filed the complaint with Sprint on December 22, 2017. and they have 30 days to respond. But I have tried everything I can think of to get the phone back to the U version software without any resolve. As far as I am concerned Sprint owes me a replacement Samsung Galaxy S7 Unlocked phone or newer model, and right now the only "Unlocked" variant Samsung phone Sprint even stocks is the new S8 Active SM-G892U phone which is the same phone for Sprint as it is for T-Mobile; but we shall see what happens I am not holding my breath with Sprint and will probably just have to take them to small claims court for the replacement cost of my phone as it is cheaper than submitting a formal grievance with the FCC is the informal one doesn't solve the issue.
is there any other carrier firmware with the same bootloader version that i can flash to? i need a phone for Verizon, i'm stuck on the sprint firmware. there's a band that is disabled on the sprint one. hopefully one of the others, if there is one available, will have the bands needed enabled.

Wow - nice persistence following up with FCC! Would love to hear how that gets resolved. I'm also stuck with a 930P v5 bootloader and no way to install 930U firmware. What is the best way to track 930U firmware bootloader versions so that I know if/when v5 is released?

G930UUES4BQL1 is bootloader 4.
G930UUEU2APG9 is bootloader 2.
G930PVPU5BQJ3 is bootloader 5.
At the end, go 5 digits back and you will get the boot binary version. So when the U firmware gets to G930UXXX5XXXX it should be good to go. Based on the U history, it looks like the bootloader will get updated if/when oreo gets dropped to the device. It seems like they went with 2 for MM; 4 for Nougat; and hopefully 5 for Oreo. Every carrier seems to be updating the bootloader version about 5 months before the actual release of the new OS...maybe that means that Sprint will be the first to receive Oreo.

Thanks so much for the great info!
If we wait for oreo and it has bootloader 5 then it will be great assuming we do not update the sprint oreo first potentially changing the bootloader version number again. Would be great but I guess now we will just wait and see

Did we ever get an update on this?

Why AT&T makes it so hard to update their phones?

Hi,
I really love my G892A S8 Active that I've purchased used in Canada.
But for some reason AT&T don't want their phone to be updated while on another network. This is the first carrier I've seen that does that (blocking OTA updates). Any real reason for this?
I've even tried with a prepaid SIM card from AT&T and paid the 35$ plan to later found out that you really need to be on the AT&T network (US) instead of a roaming network with a working ATT plan.
Even the attcompute.com site where I used to get OTA updates looks it is now blocked from any Canadian ISP.
xdmd.sl.attcompute.com/agents/48974/1488/SS-G892AUCS2ARA1-to-U2BRA3-UP
This used to work 3 weeks ago with the phone user agent. Now, all attempts return DNS look-up failed..
I had other carriers unlocked phone OTA successfully on another carrier network.
This is crazy... why block people from updating their AT&T unlocked phones????
And yes I know about XDA OTA source but it is not always up to date and depends on user base to upload OTA and make it available to general public.
Last security update is G892AUCS5CSH1 but I cannot find it anywhere... not even on xda.
Thanks!
Laurent
I have the exact same problem. I was able to find the pie update but not the last G892AUCS5CSH1 security patch.
they don't do it, because it will broke the sin unlock
The latest baseband for the AT&T version of the Galaxy S8 Active (a.k.a. the G892A) is G892AUCS5CTL1. You can find it linked from this post or this one and install with Odin 3.14.1.

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.
I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?
not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.
Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.
Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind
