I have a AT&T Samsung Galaxy S4 (Unlocked) and I am currently using it on Cricket wireless. The phone is currently running on Android 4.4.3 and I would like to update the same to Lollipop. Samsung Galaxy S4 got Lollipop rolled out by AT&T recently but I was not able to get the same since I switched carriers.
Now what is the best way to update the phone. If possible I don't want to root the phone. I went to best buy local store but they were not able to do the same as they said the phone is unlocked. Please let me know how I can update my phone to the latest version. It will be really helpful if someone can point me in the right direction.
Thanks all in advance for the help.
Will putting a AT&T sim in my phone help with the OTA? In the sense if I get an AT&T sim card from someone or purchase one and put it in to my phone will that help with the OTA? I am not sure if this phone was unlocked by AT&T.
I was able to successfully install the updates on my phone. I was able to downgrade my phone by installing stock 4.4.2 using ODIN and then was able to upgrade my device to 4.4.4 first and then update to 5.0.1 via OTA. It was an easy process and the instructions in the ODIN thread was really helpful.
Similar situation
I too have an unlocked SGH-I337 that is unlocked from AT&T and I'm using it on T-Mobile. How did you perform the Lollipop update without an AT&T SIM? I took mine to the Samsung experience at Best Buy and they weren't able to do it via Kies and they believe it's because it's unlocked. Nothing else has been done to it, just the AT&T unlock so that I could switch carriers.
Thanks in advance,
Charlotte

I'm new to rooting ATT phones, my wife just go a free ATT S4 I337UCUFNC1 from a friend and I want to root, convert it from ATT to T-Mobile phone then unlocking it.
The phone doesn’t have a sim yet but I'm planning on putting my wife's present T-mobile sim in there.
I'm very familiar with the T-mobile Samsung S4 version.
I've read that I need a safestrap after root?
Can I update to 4.4.4?
Can someone point me in the right direction?

Follow this to root http://forum.xda-developers.com/showthread.php?p=56453100. To run on tmobile you'll have to sim unlock it. Try regionally away

To Sim unlock, flash the MF3 modem in safestrap recovery and then run regionlockaway app.
Thanks alot, I was able to boot in Safestrap Recovery but after I rebooted from that and then tried to reboot back into Recovery Safestrap FC'ed. I tried uninstalling the app and reinstalling it but is FC'ed again, dunno what's it going on.
How do I get back into Recovery if Safestrap is FC'ing? (I'm trying to flash the MF3 modem)
NVM, Got back into recover, flashed the modem now and used Region SimLock, I took my T-Mobile sim and put it in the AT&T phone and it works.
Now I will try to convert it from AT&T to a T-Mobile Phone using : http://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719
Quick Question
If I use this method to convert from a AT&T to T-Mobile will I loose the Unlock Sim?
Would I be able to use Region SimLock again with the being updated to 4.4.4?
Got everything going... completed!
Thanks!
I currently have an unlocked Galaxy S5,g900v (b), looking to update to lollipop. I use a tmobile sim so I will not be getting any OTA's from verizon. How can i update to lollipop without installing custom rom, and maybe with a tmobile instead of verizon pre loaded apps/settings.
Thank you.
I have an unlocked AT&T_ S5 with a T-Mobile SIM card. I want to update to lollipop and my phone won't update automatically through my settings so I suppose I gotta d/l and update but which update do i d/l? AT&T or T-Mobile?
The at&t s5 (SM-G900A) variant has locked bootloaders, meaning you can't flash any other ROM's besides the stock att rom, unlike the rest of the T-Mobile or other s5 variant communities do. At&t hasn't released the lollipop update yet, and they released an OTA update, still KitKat, recently. So head on over to the att section of the forum and you will see there is a safe strap method available, but I haven't personally tried it.
Hi, I've been searching for a solution for failed Lollipop update on my AT&T device. I bought my device with AT&T and switched to T-mobile with sim unlock a year later. I'm currently running N900A...NC2 (4.4.2). My device is rooted but i haven't done much after rooting it except removing some bloatware. I'm able to download the OTA update that AT&T is pushing (at least i think its the lollipop update). However, after download the installation fails. I don't know if this is because i'm not with AT&T any longer or is it because my device is rooted. Tried calling T-mobile with no avail. Wondering what my options are at this point.
I read in a thread here that DO NOT FLASH other carrier's stock firmware with ODIN. How true is that? I'm pretty novice at Android devices. So any help/suggestion is appreciated. Thanks in advance.
Root can stop OTA.

I recently bought my s7 edge directly from the samsung website at&t version and got it unlocked to be used on the tmobile network. I tried updating the phone to nougat but at&t software update would say that I am on the latest software which was 6.0.1. I even used a working at&t sim card because I thought maybe you need to be on their network but still it gave me the same thing. Finally I just used odin to update to nougat but I wanted to know if anyone knows why I was not able to update ota?

You are on the international version if you bought it directly from Samsung. They haven't released the international N for the S7 Edge. I know this is frustrating but you aren't the only one. If you can put up with ATTs bloat then go flash the Odin files, they have been released for ATT.
