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 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,

I, too am in the same situation. I even bought an AT&T GoPhone SIM to try, put it in, thinking it would work (Just $5) but it didn't so, I am thinking that I need to actually activate the SIM now, but not sure if I want to add a min of $30 just to "See" if it will update.
That is exactly what you will have to do (or root your phone and then return to stock).
AT&T only does OTA updates, and only if you are an active AT&T customer. Sucks right? Don't bother complaining to the FTC, they will tell you to eff off.

I'm also using an AT&T H910. Can't receive any updates. I entered the developer options and saw that the phone was "OEM unlocked". Can I just flash a custom recovery and SuperSU to get root?
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
I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
