S8 Active Help (Baseband version is G892AUCS2AQL1) - Samsung Galaxy S8 Questions and Answers

Hello guys. As I do not live in the USA, i do not have a AT&T SIM and my phone never got any updates. Initially, it was on baseband version G892AUCU1AQG4. Till recently, I was stuck in this version. I managed to update to G892AUCS2AQL1 using links from a Russian forum. But, the SS-G892AUCS2AQL1-to-S2ARA1-UP.zip is corrupted and so I cannot update beyond this. I would be highly thankful if anyone could help me find a working copy of this file.

No AT&T or T-Mobile Service with SM-G900FD After Marshmallow Update

I recently purchased a used SM-G900FD that worked with both TMobile and AT&T when I looked at it. I checked the IMEIs but then things got weird.
I wondered why it was still on Kit Kat and wasn't updating OTA, so after some reading I downloaded Phone Info. I noticed two things, S/N was 00000000000 and it was rooted. So I downloaded Odin, and I think I downloaded the correct firmware.
I am now in 6.0.1 but the phone info now says it is not rooted and I can't get service from AT&T or T-Mobile. Do I need to be rooted to get service?
What did I do wrong? I hadn't used it because I was waiting on a case and wireless charger, but I broke my zenphone 2 screen today and need to start using the S5 ASAP.
I am new to rooting, so any help is greatly appreciated.
A few other things I should mention.
Phone Info "Country of Origin" is blank.
And the firmware's CSC code is CAC.
Firmware is currently G900FDXXS1CGP1
Again, new to this so any help is appreciated.
Thanks.

How to update S8+ from ATT outside the US

Hi everyone! I bought an unlocked S8+ from a friend and I'm using it outside the US and I haven't been able to update it, I still got the April security patch. Does anyone know a way to update it. I have already tried to update through settings and it shows that it's update to the last version, even though is not true. Any help will be really appreciated. Thanks!

Can someone please help?

Hi all I'm super new to this so I'm hoping someone can help me and I hope I'm doing this right. Thanks for your time ?
I live in Perth, Western Australia and recently bought an unlocked ZTE axon 7 mini (ex display) from a local retailer for a steal.
I can't seem to get it to update though through its native update program (just says network unavailable)
It's running Android 6 marshmallow and I know that it can run nougat (I'm hoping Oreo too maybe? Or soon?) in other countries and I'm hoping one of you brilliant tech wizards can help me as I feel the phone will benefit greatly especially with the battery life. Here's it's particulars
Model - ZTE B2017G
Android v - 6.0.1
Build - ZTE B2017G APV1.0.0B01
If you need any more info (like baseband or kernel, not sure if you need that?) please let me know I'll update this thread.
Thanks again!
Did you manage to update your phone firmware?

Trying to root AT&T Galaxy S7 on Oreo

Hello,
I'm new to this whole root business, and I wanted to try it out on my wife's old Galaxy S7. I followed a guide on tenorshare.com.
When I tried to root the phone, I got an error that said "Odin version protocol error." So then I downloaded a different version of odin and then I made it past the first error, but then got one that said "Fail! SHA256 is Invalid". I've been looking around and can't find any clear answer. The phone is a Galaxy S7 on AT&T, running Oreo. It is model number G-930A.
Just wondering if anyone can help. I'd really like to try out a rooted phone, but it's proving harder to achieve than I thought. Thanks in advance!
Well if you have a regular S7, you're on the wrong forum. This one is for the S7 Edge AT&T models.
Here's where you need to be posting at for your phone.

Sir, it means that your baseband doesn't have that kind of firmware.

Got a phone from a foreign country.

Hi, so I got an AT&T Galaxy S10+ (SM-G975U) from the US and it was stuck at Android 10. I can't get any updates so I tried to flash a new firmware into my phone. The problem is, SamMobile doesn't provide AT&T firmwares for SM-G975U but other carriers like T-Mobile and Verizon is available. Can I use firmwares from other carriers for my AT&T phone?
Yes
I need help i own a S10 plus model SM-G975U AT&T variant, it runs android 10 with UI ver 2.5 I cant update the phone through its update options located in settings. I see new Android 12 Update have been released i want to update my phone can someone please tellme what CSC to use ? What PDA to use ? exactly which version of firmware should i install ? i know i am asking like a noob but please i really need some expert advise. P.S i dont know if my phone is unlocked or not ... how to check that either ? Moreover Expert Opinons be communicated to my email address which is: [email protected]
I would advise anyone looking to update not to update beyond Android 11. Android 12 has issues and not just on Samsung devices. You can download Android 11 for all US Variants here.
