No Love For SM-T818A (AT&T)? - Galaxy Tab S2 Q&A, Help & Troubleshooting

So I have an AT&T Galaxy S2 currently running Baseband Version: T818AUCS1AQD1 (6.01). I like another member in this form have been unable to find anything useful as far as rooting my device. I cant even get my tablet to update though the regular software update process. I no longer have a SIM card in this device as i purchased it on Craigslist (not sure if that makes a bit of diffrence. Everytime i try to update my software it tells me im up to date. I took it to AT&T and they told me to take it over to the samsung rep at best buy...what a joke. Anyways As of today it is missing two update,
1. Baseband: T818AUCU1BQE2
Build: NRD90M.T818AUCU1BQE2
And
2. T818AUCS1BQH1
All i really want to do is root this thing and get it updated. the only thing i have been able to find as far as firmwares are concerned are ones from Turkey. Im not the brightest bulb in the box but i'm thinking this is definitely not going to work. Everything else i have found does not include the "A" after the "SM-T818" so im very hesitant to try anything when i have minimal knowledge about this device because it is AT&T branded. At this point i know its a long shot as i know many people have moved on and this device isn't getting much attention it once did. I don't want to screw anything up so any information anyone can provide would be GREATLY appreciated. Thanks in advance.

[Q] about to buy a GT-I9000- A few questions to owners

Hi guys,
I am ready to finally get rid of my tmobile wing! I finally made my decision to go with the international version of the SGS. Well, almost, I do have a few questions to owners and US users in particular:
- I would like to know of really bad known issues of the phone. Every phone will have some issues, it is a given, but what I am talking about is issue like the captivate where a lot of people have random shutdwon of their phones. I would like to know if there are any similar issues with the SGS that will prevent basic operation of the phone ( I know about the gps, and I am fine with this problem)
- How is reception, drop calls and call quality on the ATT network, and if someone is in FL, please tell me about your experience.
-I am aware of the fact that the phone has only 1900 Mhz band but I have been looking everywhere for a map that will show where the 850 vs 19000 3G areas are and I cannot find one! so if someone knows where to find one please a link would be great.
Thanks so much in advance for any input.
sure there are owners who can answer at least the first question. Please!
You need to wait for USA ATT owners to read your post .

Well, I would think any owner could answer my first question. that would be helpful, to make sure I am ok buying the phone. I am in a dire need of a new phone as my current one is falling apart. So if anybody who knows about this phone, it would be nice if they could chime in.
Thanks in advance!
I can't really answer anything about the reception on AT&T, but the problems with the phone there are lockups. It can freeze. But if you flash a custom ROM onto the thing, it runs like a dreaaam.
I have been bugged by the lagging on the first week i got the phone. managed to apply the lagfix and seem to be doing great so far. I'm planning to wait for official gingerbread from kies. Still afraid of flashing though.
Yeah dunno much how to answer your questions tho. but yeah, SGS is the best phone yet i ever had.
I've got the international i9000. From last August till now, I haven't had any problems. I put this down to 2 things, one good fortune ,and secondly it's unbranded and unlocked from new. The phone has gotten better with each firmware upgrade and now on 2.2.1 even if gingerbread wasn't coming my phones just fantastic and it's quick. The phone apparently can be rapid when its on gingerbread listening to the lads on XDA and some say it takes care of the only thing Ican say negatively about the phone, which is the battery life, and personally, (The lads on here probably know better.) I put that down almost entirely to system spyware,as three hours of internet knocks mine down to 48%, and even with all syncs turned off and all apps taken out except the sammy key board every so often all the g***l* stuff restarts itself in one form or another and you can see the little green and red data arrows active. AS a phone, I believe with this next official update coming, allowing for the gs2, allowing for it not having a camera flash, this is the best phone money can buy, yes there are dual core phones, yes a few more pixels, even yes, I'll probably at some point get the sg2, but not because it's needed , it's just what we do, after all we come to this site with the others because we like phones. Hope this helps in some way.
If you read around the forums, you'll find a lot of great things about this phone. I couldn't be happier with mine really. Reception is never a problem for me though I'm in Canada. Some people claim they have GPS problems, but there are several fixes that can help you improve/overcome those problems. They claim are that they can't lock enough/any satellites on their GPS system to get a reading, but after using GPS test app to learn a bit about the best way to detect a signal it works like a charm for me . You won't regret it, although I would probably look into a SGSII if it were me.
If you are going to be on AT&T why don't you buy the i9000m
Most of the issues in the phone have been down to bad firmware by the carriers and also a silly design decision from Samsung with regards to file systems on earlier firmwares.
Running 2.1 firmware the phone was slow as heck and my GPS which was set to Autonomous mode would take sometimes up to 5 minutes to get a fix. A simple setting change gets GPS lock within a few seconds. Also with each firmware release the phone has gotten faster and faster.
Also if you're a tinkerer then this phone is a dream. It's hard to brick, often recoverable if you make an error, and some of the well tuned ROMs on these boards are absolute rocketships for speed.
Thanks guys! You gave me great input. I will have to make a decision, but this will help me greatly.

Don't they have a problem with this phone on some interal SD card failure? Is this something that only applies to the I9000m and not the international version?
Free ram available in this device is quite low, I had an European hd2 with 448 mb ram but it always had more free ram than my i9000 which has 512mb(almost double)... more free ram means it can do multitasking better, apparently do not need to be closed ects

What to replace to change IMEI?

Bought a really nice Captivate on eBay about a year and a half ago when my carrier was swallowed up by AT&T. It came with the original box, paperwork, etc. and the numbers all matched up, so to me it was a clearly legit purchase and I've had no problems in the 18 months since I bought it ... until last night. (I no longer have any idea who I bought it from or how to contact him.) Last night out of the blue my phone was banned from the network, and long story short ... AT&T has the phone blacklisted and can't/won't clear it from their list. They're evasive as to why and what I find odd is the IMEI reported by the phone software doesn't match what's on the label. But again, never had a problem before last night. No amount of begging and threatening to switch carriers got me anywhere, even after escalating to different supervisors. AARRGGHH! So here I sit with a perfectly good phone that I can't use.
Seems the obvious solution is to rip it open and replace something with parts from a parts phone that isn't blacklisted. Might seem dumb, but what should I be replacing? I've already got it apart and am assuming it's the motherboard that holds the offending IMEI. Is that right? Aside from eBay, is there any reliable source for a replacement? I don't want to waste money replacing it only to find that the new one is also blocked. Or is there something I can do so the IMEI shown in the software is the same as what's on the label? I'm not trying to do anything illegal, just get my phone working again.
If it makes a difference, I'm running the stock 2.3.5 that came out around February, but rooted and unlocked. Could that be why the IMEI doesn't match and I took it all apart for nothing?
Thanks for any suggestions. I'm technically competent but almost completely inexperienced when it comes to phone hardware (and software), so please excuse my ignorance here.
Thanks again,
Brent
edit - oops. misread
I did just see that someone was talking about their IMEI being replaced by a generic IMEI, but that was due to flashing Jellybean. If you want to try to restore your phone to its own stock IMEI, you'll need to rebuild your /efs folder to get the phone to bring your correct IMEI back on. There's a thread in the development section that outlines how to do that.
My only other suggestion would be to go into a physical store (if you haven't already) and plead your case in person. People tend to be a lot more willing to work with you if they're dealing with you face-to-face instead of over the phone. Just state your case clearly, show them any materials you have to support your case, and be friendly with them. I would also suggest flashing back to full stock (unrooted) so they can't use that against you.
Thanks. I found that thread after posting but so far it has not worked for me. I just decided that for $30 it's not worth the hassle of trying to fix it on my own, so I'm sending it off to MobileTechVideos following recommendations elsewhere here.
Its super easy on the captivate. There's literally an app that restores it back to Froyo and the correct IMEI. Then you use the Kies to upgrade into GingerBread. If you got as far as rooting I'm sure you could do this.
Unfortunately I dont know what its called but I searched a lot and eventually you'll find it. It looks a lot like the Odin app

I figure for $30 (already spent; phone's already in the mail) it will save me the hassle of tracking down the software you mentioned, going through all the upgrade/root process, and restoring everything that was wiped out. Let's hope, anyway!

**Reward to fix my phone**

Hi all,
Pretty cut and dry.
Anyone want to get paid to fix my phone for me?
I was running the AllianceROM for years with ZERO problems.
I upgraded to the Note8 a few months ago and gave my phone to a buddy to use because he broke his phone and was desperate.
Well I guess he considered himself a tech person.
He wasn't.
I think he tried to install a different Rom on it because he mentioned updating it to Nougat. The only ones I've seen are for the International 900, and he basically bricked my phone.
Details :
Screen stays on Samsung Note 3 splash screen. I can access recovery. Connects to KIES. Connects to Odin.
Honestly I could probably mess with it, but I just don't have the time.
I just want it fixed and the Alliance ROM put back on.
I will send it to you, pay you to fix it, and give you extra to ship it back to me.
Anyone game?
Thanks guys,
Jack
Boot the phone into download mode to find the model number.
If the model is not sm-n900a:
Download the latest stock ROM from sammobile.com, update.com, or Samsung-firmware.org.
Flash the stock ROM using Odin.
Perform a factory reset right after flashing with Odin.
If the phone is an sm-n900a: https://forum.xda-developers.com/showthread.php?t=2703006
Thanks for the suggestion.
I already know it's an A model.
Original offer still stands.
Anyone want to make some decent coin?
Look, I know I can pick up a new one on Ebay for like $100, but then I'd have to root it and put a ROM on myself. Not tough, I know. I did it to this one and every phone I've owned.
This particular phone has sentimental value to me. It was the first Note I actually hotrodded and loved. Had the 1 then the 2, but I just really loved the 3. Obviously, considering I've kept it around for the last 5 years and kept going back to it.
I not talking giving you $20 to fix it. You'll be aptly compensated for your time. I'm just to busy to deal with it and would prefer to just pay someone.
No BS. No games.
Admins?
ROM writers?
There's a Franklin with your name on it if you want.

Whats the best way to copy/flash one S10 over to another S10?

its been a minute since i flashed phones, especially samsungs. i have two tmobile S10's and i need to make an exact copy of one S10 over to the other. i remember doing something like this with an LG phone i had back in the day and i'm sure its possible to do it with the samsungs probably using odin? anyone can point me or give me a quick refresher on how to do it? i searched the forums but couldn't find exactly what i was looking for (user error most likely, sorry). both phones are stock Tmobile they do have different basebands (probably update one or the other should fix that). other than that they have the same software installed.
as a side question, would making a mirror image of one phone onto another save all the settings and everything? i'm pretty sure it would, but just in case. thanks!

Possible to Root a Verizon Galaxy S8?

So I'm sure this has been covered elsewhere but the XDA search is yielding nothing fruitful.
I have a friend that is looking to root their device and turned to me. I have rooted all my devices, but I don't use Samsung. I know that the galaxy line is extremely popular and typically able to be rooted, but I also know that US carriers also like to issue their own version of the device and tend to lock bootloaders and root ability.
Can this actually be done.? What is the easiest method?
I would love to provide you with model, android version, and build number but I'm not dealing with the most tech savvy person so I'm going to have to take a look for myself. At the very least I'm hoping someone can point me in the right direction or inform me if it cannot be done.
Thanks in advance.
I have an s8 SM-G950U and it took me 20 minutes to root it using https://forum.xda-developers.com/galaxy-s8/development/root-t4060701
