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
This is really confusing. Most of the threads are written such that 'how to root while updating to OF2/OF3'...it doesn't tell me which versions allow rooting in the first place? Any help. Coming from the GS3
As far as I know, the S5 Active is only available as an AT&T phone, which means it will have a locked bootloader and any somewhat newer firmwares will be unrootable. Pre-lollipop builds (Anything below OF2) are rootable but still have a locked bootloader.
Just a word from the wise, don't get an S5 Active, and DEFINITELY don't get an AT&T phone. a GS5 (regular) with a thin case (Spigen slim armor or neo-hybrid/ otterbox commuter) will be WAY more durable anyway, plus it's still waterproof/dustproof.
Get yourself a G900T (T-Mobile variant), or a G900AZ (Cricket wireless variant --Cricket is a subsidiary of at&t--), or even a G900F. Those all have unlocked bootloaders and will allow you to root, install custom recovery, custom roms, whatever you want forever. I personally have a G900T using it on AT&T with no issues, as the G900T supports all the same frequencies (and an extra one!) as the G900A (AT&T model). The G900F doesn't support every single band AT&T uses, so I would pick one of the other two if you want 100% compatibility.
MAKE SURE if you buy a G900T or G900AZ that it is UNLOCKED or you won't be able to use it. And after you get it, you'll have to call AT&T support and give them the new phone's IMEI number in order for LTE to work.
Hope what I said makes sense..
FYI The best place to buy a phone is always (XDA's own..) Swappa!

I habve an at&t variant OC5 phone available on Swappa should I get that or not, because I can't find a rooting guide for OC5
Or are you saying buy unlocked so you can use it on AT&T?
Problem is I can't find the SM-G900AZ anywhere used....might just go with the Zenfone 2 . DISSAPOINTING SAMSUNG and ATT I loved the GS3 and was looking forwar to the GS5
Which frequencies does the T mobile version NOT share?

The T-Mobile version shares all the same frequencies plus includes an additional frequency which AT&T does not use, so therefore the T-Mobile (G900T) retains 100% compatibility with AT&T. Yes, if you want to use a G900T on any carrier besides T-Mobile it will have to be unlocked. Luckily it's not hard to find an unlocked G900T.
Let me make this clear: If it's AT&T and it's a Samsung phone and it's on lollipop, don't expect to be able to root it. Go with a T-Mobile or factory unlocked phone.
Hi,
I want to buy a Note 4 and absolutely need root on it. I just found some ugly stuff about rooting it:
http://forum.xda-developers.com/note-4-att/help/root-samsung-sm-n910a-5-1-1-build-t3355869
quote:
----------------------
forgot to tell you the two U.S. carriers that put locks on their bootloaders is AT&T and VERIZON so i wouldnt recommend root unless you unlock bootloader or else your phone will continueously stay in boot mode without letting you exit. that i believe is a bootloop good luck
-----------------------
Since I can chose which one I buy, I obviously want to get the one that can be rooted. It does not have to be easy, I have used odin in the past, no problem. There are quite a few versions out there though, and I'm a little confused which ones will work. Looks to me like that N910A is out and root pretty much impossible.
I have my eyes on the canada version: N910W8
What about the T-mobile version?
Thanks,
Markus

AT&T and Verizon should be avoided, otherwise you can just flash super-su via odin.

910t is mod friendly. To root a 910t, you flash Odin and load SuperSU (systemless) as indicated above or flash a permissive kernal and system level root. It is also compatible with att network if that is your carrier. Just need to unlock it.
Thanks guys, that helps, I will go for a 910t then.

Bit of a noob, but I'm a bit confused. If I buy an "Unlocked" Verizon phone like the SM-N910V, would I be able to use any custom roms?
I was about to buy either the N910V (Verizon) or N910W8 (Verizon/North America)
Can't the Verizon & AT&T be rooted with Chainfire AutoRoot?

Only if you buy a developer edition verizon model and last time I checked they were upwards of around $800. Your best bet is W8 or T. I did all the research like you and ended up buying a T and have never been happier

(Unlocked means sim unlocked)
Bootloader Unlocked verizon phones can be flashed with a custom rom, and if you get a verizon phone, I suggest a Bootloader unlocked one. Verizon and AT&T phones with locked bootloaders can't be rooted with Chainfire. Chainfire should NOT be used on a phone with a locked bootloader because it flashes partitions and will most likely hard brick your phone. I would still sugest against a Bootloader non-unlocked Verizon or AT&T phone. Also using a custom recovery or odin to flash super-su has worked much better for me with a lot less less risk than Chainfire.
Whatever you decide upon dont get the EDGE. it needs special roms, and it wont work with gear VRs. i have the euro verison, and didnt have any problems rooting. cf-autoroot and done.
Really appreciate the responses guys. Especially for the clarification around Unlocking ("Unlocked means the bootloader").
I'll check out what custom ROMS work on the Verizon (910V).
Are there more ROMS for the 910W8's or the 910V's. Also if I go stock on the W8s, I would have to choose a Canadian carrier.
I'll definitely stay away from the EDGE, didn't really like it anyway

Careful there, usually 'unlocked' like on Swappa or similar means carrier unlocked, not boot loader unlocked.
Device is unlocked and I finally got to move over to T Mobile. Went through HELL however got it done and was well worth it. Speed is like 100 times better ( was getting .01 DL speed on Sprint and now its 20.0 MB!!!! Long story with a different thread about it right here on the XDA if you are interested.
New problem is that I have just read online about Sprint coming like a month later after you moved over to T Mobile and re locking your S7 after its working on T Mobile (https://community.sprint.com/t5/Pro...longer-accepting-TMobile-sim-card/m-p/1023474).. They then allegedly fix the problem but I naturally want to prevent it all together.
Any way to make sure they can't do this to my paid off device?
Should I flash the G930T firmware or the G930P T-Mobile variant? Or maybe I should just stay with the latest Sprint version which is the one that is running right now?
Im on v9 bootloader so Ill have to wait if the best is the G930P T-Mobile variant Firmware. in order to prevent Sprint from relocking my device.. Theres currently a Virgin Mobile, 2 Unknowns and a Sprint variant for the v9 bootloader https://www.sammobile.com/firmwares/galaxy-s7/SM-G930P/.
Any insight into any of this is highly appreciated. Thanks.

I moved to cricket and my phone didn't relock. I would either Odin the T-Mobile if on 9 or the U firmware, since it is on 9.
Hello! I've been out of the Android scene for a few years so I have a question that I can't seem to find the answer to by searches.
Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.
I had a Galaxy S8+ when it came out and I used Odin to flash between U1 and AT&T firmware so the process isn't entirely new to me.
A bit of background:
I'm looking to jump off of the dead iPhone train and hop back into Android with the S10+. I'm currently trying to sell/trade my iPhone XS Max in order to make the switch.
I have someone who is willing to trade me their Black S10+ for my iPhone as an even trade but their S10+ is from Verizon. It's unlocked but it's still running the stock Verizon firmware.
I just want to know what I have to do with this trade in order for it to work for me. I want to make sure I get a phone I can use. Any advice or input would be greatly appreciated!
Thanks for any help!
I'm not entirely sure if this will work on the S10+, I haven't tried it yet, but when I had the S8+(it was from Verizon as well), I'd take it internationally with a different sim card, it would just prompt me to reboot the phone and it would automatically apply the appropriate CSC settings. I was on stock VZW firmware as well and VoLTE worked (wifi calling didnt).
You should be fine either way though, people have successfully flashed the U1 firmware on their VZW devices for the S10+, so you shouldn't have any issues getting your AT&T sim card to work on it.
Edit: link to get the U1 firmware

I wish Samsung included the BYOD update in the S10+, that would make it so much easier. I think I'm just gonna make the trade.
I've read through that thread and that's what I think I'm going to do. I'd much rather flash the AT&T version, but seeing as how it's not available, the U1 will do fine until it's released. I'll just need to switch to a different voicemail service in the meantime. lol
I got a Verizon S10+ and it is running build PPR1.180610.011.G975USQS2ASGB, I have confirmed that putting an AT&T SIM gives me network ability to call and what not. I want to flash the stock U1 branded firmware, is it okay if I flash G975U1UEU1ASD8 with Odin?

HEY I know have the same problem... Does it work.., I have installed the firmware and all so should I go for it.., waiting for your reply
I have Verizon unlocked phone and I'm able to use internationally where there is no Verizon, but I'm not getting updates so I have downloaded latest firmware should I flash it, also now I don't need any Verizon sim after flashing right ?
Yes you can flash U1 firmware to a U device and vica versa. The U means Universal, so you can flash AT&T, Verizon, T-mobile, or unlocked firmware to it. You gotta use the patched version of Odin though.

As Just changing csc without installing the system is more than enough. Even the company logo changes. Just look for the samkey program and you will see
