[AT&T Samsung Galaxy S6] Red5:
U3CPD6?!? What rom is this???

How did you find this?
[AT&T Samsung Galaxy S6] nsmith4:
Was bored wanted to see if another higher number rom worked so I tried C3,C4, etc. since that's how their previous rom version numbers seemed to work and went until it stopped finding a file. D6 was the last one, D7 found no file. Looking into the zip it gives this as a version G920AATT3CPD6. Think I'll wait for AT&Ts OTA after seeing this, seems like they might still be working on it.
[AT&T Samsung Galaxy S6] Dante087:
Soooo is someone going to flash this?
[AT&T Samsung Galaxy S6] Red5:
DId you find that in the CSCVersion.txt file? The 'AATT' is used for the sales code.

Nice job on finding more. Was it just the two roms, or were there several?
[AT&T Samsung Galaxy S6] nsmith4:
Ya, found that version number in that file.

There were several more up to C6 and D1-D6.
[AT&T Samsung Galaxy S6] Red5:
Ah, so then C2 is not the final version and wont be the OTA rom.

It would be interesting for someone that already checked out C2 to look at D6 and see what has been added and taken away (such as app optimization, quick charge toggle, video calling...).
[AT&T Samsung Galaxy S6] s629c:
I might just stick to pc2 cause it is pretty great. Don't want new bloat
[AT&T Samsung Galaxy S6] kwd114:
I wonder why the Samsung site lists the C2 version as the most current?
[AT&T Samsung Galaxy S6] Red5:
That was probably the first base that Samsung gave them, and once AT&T gets it they keep baking more into it, then test it... then bake more and test more.

Does anyone know how AT&T names their software versions? Such as each letter is supposed to represent the weeks and the last number is how many times that week they tweaked it, or something like that?
[AT&T Samsung Galaxy S6] s629c:
Did my math wrong earlier. As of now, I'm at 52% with over 2hrs of sot so i may be able to get 4hrs of sot. About 1hr 30 min increase from OJ9
[AT&T Samsung Galaxy S6] RoryB:
I wonder if a file compare of the updater-script files would tell us enough about the differences.

I don't have a good internet connection to download the new one, but if someone could extract the two script files I would be glad to compare them.

Otherwise we would have to compare the contents of all the sub-folders.
[AT&T Samsung Galaxy S6] s629c:
What "script" file am i looking for specifically? I can download them.
[AT&T Samsung Galaxy S6] RoryB:
Extract them from the OTA files by renaming the OTA files to have a .zip extension.

The path should be META-INF\com\google\android\updater-script

Please rename the updater-script files to match the version of the OTA file

Thanks
[AT&T Samsung Galaxy S6] Red5:
I'll get those for you right now.
[AT&T Samsung Galaxy S6] scorpioncom:
The last 3 are 2 digit year, month and Rev. Where year and month are the number position of the letter in the alphabet.

OJ9 - O = 15 ( 2015 ), J = 10 ( October ) Rev 9

PC2 - P = 16 ( 2016 ), C = 3 ( March ) Rev 2

PD6 - P = 16 ( 2016 ), D = 4 ( April ) Rev 6
[AT&T Samsung Galaxy S6] s629c:
Oh. That makes more sense
[AT&T Samsung Galaxy S6] jznomoney:
I chatted with AT&T today and the rep had no information on marshmallow or even if we are getting marshmallow.
[AT&T Samsung Galaxy S6] s629c:
Try a different rep? User in note5 forum talked to att rep and said update is coming
[AT&T Samsung Galaxy S6] bryantx24:
I ask another rep just in case and this is what I got

http://imgur.com/OlOI7JS
[AT&T Samsung Galaxy S6] s629c:
Late night rollout maybe?
[AT&T Samsung Galaxy S6] jasonstackhouse:
And there was no release, AT&T crapping the bed yet again
[AT&T Samsung Galaxy S6] Cusa:
Just chatted with a rep and they said it will be out this upcoming week.
[AT&T Samsung Galaxy S6] KnownDominance:
We may never know! Lets wait until tomorrow and hope it happens
[AT&T Samsung Galaxy S6] s629c:
Note5 never got the update. Don't think we'll get it either.
[AT&T Samsung Galaxy S6] Croeta:
Just had a chat with a rep. Don't know how well this will help. I am going to guess tomorrow since that's what all the reps are saying.
[AT&T Samsung Galaxy S6] Cusa:
I highly doubt we're going to get the update today.
[AT&T Samsung Galaxy S6] KnownDominance:
If anyone gets it let us know, my ROM has software updates disabled
[AT&T Samsung Galaxy S6] Zero4:
Maybe they meant it will be released at 11:59:59 PM on 3/14. [emoji38]
[AT&T Samsung Galaxy S6] Cusa:
I will PayPal everyone in this thread $10 if the update gets released today.
[AT&T Samsung Galaxy S6] s629c:
Att reps now say note5 don't get till March 30th so they were just BSing the whole time
[AT&T Samsung Galaxy S6] archie87:
AT&T is usually the last to update. I'd be quite surprised if they managed to update it before the other big wigs.
[AT&T Samsung Galaxy S6] drewiskee:
making this post just to show im present incase they release it 11:59:59pm today
[AT&T Samsung Galaxy S6] jtp2293:
A representative today told me that they do not know this information. They spoke to their manager, and the manager stated that we would receive a text message when the update is ready.

Getting increasingly more frustrated with Samsung and AT&T waiting for months to receive an update for something the S7 already has...:mad:
[AT&T Samsung Galaxy S6] sdk0308:
Hopefully the make a S7 Google Play Edition. I'd much rather save up for that than deal with AT&T's bloatware and delayed updates.
[AT&T Samsung Galaxy S6] jtp2293:
Absolutely agree. I love my S6. I switched from iPhone to Samsung and have no desire to go back; however, the one thing that Apple has over Samsung is rolling out updates much faster and more efficiently. The bloatware (which is typically disabled anyway) is excessive and such a nuisance.

Hopefully we will get the lucky notification for the update soon. Been waiting too long for this!
[AT&T Samsung Galaxy S6] Ed_Sanchez:
I spoke with an AT&T Rep today and they told me that the 6.0 update for Galaxy S6 was released on march 9th.
[AT&T Samsung Galaxy S6] kwd114:
Here is the file from the D6 update.
[AT&T Samsung Galaxy S6] kwd114:
And here is from the C2.
[AT&T Samsung Galaxy S6] Red5:
Here ya go, both updater-script files.
[AT&T Samsung Galaxy S6] dpw2atox:
All this and yet nothing for the edge......I wonder what the build date is of the latest firmware?
[AT&T Samsung Galaxy S6] harveson:
Run a diff on the two files.

Found these lines are deleted in D6 comparing to C2. Guess C2 was a debloated version?

[AT&T Samsung Galaxy S6] RoryB:
thanks for looking at them. I was trying to do a compare with Notepad++, but I guess the files are too big for it.

Also, ther might be more files in the system/ folders, but you would think they would show up as additional permission settings.
[AT&T Samsung Galaxy S6] Jpak88:
This is upsetting :( so we were excited for nothing?
[AT&T Samsung Galaxy S6] s629c:
No, we still got marshmallow. Just checking newer versions for changes. Either way, we kniw for sure we have PC2 as a good working version
[AT&T Samsung Galaxy S6] Jpak88:
I'm speaking in terms of an actual OTA though. What I'm gathering from the last 2 pages is that the file people found using baseband number Samsung quoted isnt wait we're going to get, and we're still at the mercy of at&t "testing" it for potentially weeks or even months.
[AT&T Samsung Galaxy S6] Dante087:
Perhaps, but we actually win because we have the update with Marshmallow and not all of their bloatware and Direct TV ads
[AT&T Samsung Galaxy S6] dpw2atox:
Well those of us on the S6 Edge are still waiting for something, anything......
[AT&T Samsung Galaxy S6] Jpak88:
I'm kinda scared to update manually ^^; will it interfere with any future updates? Would I still be prompted to update when the actual OTA shows up?
[AT&T Samsung Galaxy S6] harveson:
Checked the files. I can confirm that there is no new bloatware in D6 except for the larger size for some app folders.
[AT&T Samsung Galaxy S6] Dante087:
Did you flash it? Wondering if it has the April or May security patch.
[AT&T Samsung Galaxy S6] jznomoney:
can anyone pull the oj9 build.prop from their phone and post the file itself.

adb pull /system/build.prop
[AT&T Samsung Galaxy S6] Red5:
Hmm, I wonder if it has a different modem. If there is no more bloatware added, what are they testing and why is there at least 11 revisions (PC2 - PD6).

Edit: Yup, modems are different sizes

Edit2: So there was only 6 revisions in the month of April... and we have not seen a PE1 (May) build yet, so Im curious to see what the build dates of PD1-PD6 are. PD6 may very well be close to the final product.
[AT&T Samsung Galaxy S6] kwd114:
So the question is....can we update from C2 to D6 using ADB. Not that its super important as C2 has been rock solid so far.
[AT&T Samsung Galaxy S6] Dante087:
How does the modems being a different size affect the typical user?
[AT&T Samsung Galaxy S6] dpw2atox:
I'd guess the only way to go to the new build (and get back on the official update path) once it's officially released is to wait for a recovery image that you can flash via odin. Usually happens a few days or so after the update comes out.
[AT&T Samsung Galaxy S6] s629c:
Well the pc2 image is not modified in anyway so we may be able to still take otas

[AT&T Samsung Galaxy S6] sand_bit:
I just tried installing PD6 from OJ9, it failed, however going from OJ9 to PD5 worked like a charm. Comparing PC2 and PD5, PD5 has far smoother scrolling in the play store, and as far I can tell, fewer microstutters in the animation in general. Strongly recommend going to PD5.
[AT&T Samsung Galaxy S6] Red5:
It could be a number of things, like how it hands off between wifi/cellular, how it switches between LTE/3G and how it connects from one tower to the next when one has a stronger signal or less congested tower.

Im not sure about how Samsung modems act, but it may also directly connect to how wifi and BT work.

---------- Post added at 12:58 PM ---------- Previous post was at 12:56 PM ----------

Can we get a screenshot of your baseband, kernel and build time?
[AT&T Samsung Galaxy S6] Jpak88:
Well that's good. It's smoother and has no new bloatware.. Maybe things will be this nice when the OTA rolls out
[AT&T Samsung Galaxy S6] cesarsuarez:
file for ODIN please!
[AT&T Samsung Galaxy S6] nsmith4:
Wonder if installing SS-G920AUCU3CPD5-to-U3CPD6-UP from https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPD5-to-U3CPD6-UP, would work. Either way it's good to hear that they are making some progress with these builds.
[AT&T Samsung Galaxy S6] s629c:
Still think it's crazy that we've found a way to manipulate the links to get early builds lol
[AT&T Samsung Galaxy S6] sand_bit:
[IMG="PD5"]https://i.imgur.com/75C9KNq.png[/IMG]

I did try installing PD6 instead, but sideloading failed. I suspect the file was corrupted, and redownloaded, but I never managed to get it working. I'm currently running PD5. I went from Cricket OJ6 to Odin OJ7 to ADB sideload OJ9 to ADB sideload Marshmallow PD5. The PD5 build is noticeable smoother than the PC2 build, and doesn't seem to have any extra bloat. It's also on the May patch level.

Edit: Link for PD5

https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPD5-to-U3CPD5-UP

Add a ".zip" to the end of the file, and flash to your phone using ADB sideload if you have OJ9.
[AT&T Samsung Galaxy S6] rahilm:
What was the error you got when flashing PD6?
[AT&T Samsung Galaxy S6] kwd114:
Were you able to ODIN back to BOJ7 from the C2 MM build?
[AT&T Samsung Galaxy S6] sand_bit:
Cannot read file. I double checked that file permissions were correct. Tried renaming the file, verifying the extension, sideloading in the ADB folder. And also tried redownloading over two different networks. It just would not work.

Edit: Yes, I was able to Odin back to BOJ7 from the PC2 build.
[AT&T Samsung Galaxy S6] Jpak88:
so they have a smooth, working build with the May security patch and they aren't pushing it out?!!!!! GOD.
[AT&T Samsung Galaxy S6] gottech:
Do you need to be rooted in order to flash the c2 build? Also does it trip Knox?

G920a

I337
[AT&T Samsung Galaxy S6] sand_bit:
A few more comparisons after using the PD5 build for half an hour. The screen color is definitely warmer on the same display mode, the whites are definitely less blue on the AMOLED PHOTO setting. Most noticeable difference is that scrolling in the play store has a smoothness similar to a Nexus 6P, in the PC2 version the scroll was smooth, but seemed to be restricted in scroll speed, PD5 has a very very fluid scrolling motion and follows your finger very closely. Touch latency anecdotally seems to be significantly lower, as before the scrolling elements across the board seem to follow the finger more closely. Fingerprint sensor is working, the camera app looks a little different. The Samsung My Files app has a different icon, and all the apps are more up-to date (the play store prompted for fewer updated when I first opened it up). No game breaking bugs yet. This is the build you want!

Edit: you do not need to be rooted, but you do need to be on the OJ9 version, does not trip knox, also use PD5 instead of PC2. Link here: https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPD5-to-U3CPD5-UP

It has the May security patch level.

I went from Cricket BOJ6 to Odin BOJ7 to ADB sideload BOJ9 to ADB sideload PD5.
[AT&T Samsung Galaxy S6] Jpak88:
I've never manually updated an OS before and I'm not confident enough to start now :/ I'm so maaaaad that they haven't pushed the OTA yet. Do you think we'll get this build, or the PC2?
[AT&T Samsung Galaxy S6] TMar00:
If you had just installed ADB did you happen to reboot your computer after doing installing? Mine kept saying it could read the file but after a reboot it work perfectly...
[AT&T Samsung Galaxy S6] Zero4:
I think the links may have finally been blocked by AT&T. I just attempted to download PD5, but I got '403 Forbidden'

If anyone has it, can they put it on a share? TIA
[AT&T Samsung Galaxy S6] s629c:

[AT&T Samsung Galaxy S6] Red5:
PD5 is 1.3GB (just like PC2), but PD6 is 1.5GB so that makes me wonder what they are doing. They finally tweaked the rom to where it was good (PD5) then did something to it that added a bunch of space.

How is your signal, wifi, BT and internet speeds compared to what you're used to with OJ9?
[AT&T Samsung Galaxy S6] RoryB:
How did you get from PC2 back to OJ9 to load PD5?

I ask because you said you compared PC2 and PD5 and noticed a scrolling difference.
[AT&T Samsung Galaxy S6] sand_bit:
Wifi speed is comparable, BT speed is comparable, signal is the same, haven't really tested LTE yet.

I'm working on getting an upload, you might have to wait a bit.

Edit:

[MENTION=1190747]RoryB[/MENTION]

I odin-ed back to OJ7, sideloaded the OJ9 OTA, then sideloaded the PD5 OTA.

I would like to comment and say that this (in my XDA experience) has to be some of the best collaborative effort to seek out the ideal software for our device.

Yeah, its actually CP2 to PD3, but there is no advancing from PD3. Currently trying to find a new path.

There are some beautiful people on this thread. Now can this go from PD3 to PD5 or do I need 4?
[AT&T Samsung Galaxy S6] troyboytn:
If you Odin back to your previous firmware you should be able to find the address yourself by initiating a manual update by dialing ^#8736364# in the dialer afterward and then click software update and reading the Server Address in the "Result" tab
[AT&T Samsung Galaxy S6] Dante087:
Can't find anyway from PD3 to PD5, 5 or 6 unfortunately... Only OJ9 to PD5
[AT&T Samsung Galaxy S6] ¿Will-it-Blend?:
Lol, so I'm just loading PD3 and I'm stuck. Oh well, let me go find OJ9 [emoji43]
[AT&T Samsung Galaxy S6] Dante087:
Anyone have instructions for Odin? I've never done that before
[AT&T Samsung Galaxy S6] iceman4357:
So then which build is the best? Seems like PD5, but not very many people on PD6 yet. Can you comment on PD5 vs PD6?
[AT&T Samsung Galaxy S6] s629c:
I don't think anyone has tried pd6 yet but given the 200mb increase in size, we expect more bloatware

Btw guys, i should have posted that dialer code earlier ? didn't know it would be so useful.
[AT&T Samsung Galaxy S6] Dante087:

I've only tried PC2... Sideloaded it yesterday
[AT&T Samsung Galaxy S6] RoryB:
Anyone have an Odin back to OJ9?
[AT&T Samsung Galaxy S6] ¿Will-it-Blend?:
PD5 is almost loaded. As soon as it's done, I'm loading PD6, I'll note any differences

Just ODIN OJ7 and OTA to OJ9. Took me 10 minutes tops.

OJ7 is taking too long tomorrow... looks like I'll have to wait until tomorrow night to get up to PD5/6... hopefully there is a newer version or just an OTA by then
[AT&T Samsung Galaxy S6] mnp261194:
Ok now i'm confused so far Android 6.0.1 the builds are PC2 -> PD3 -> PD4 -> PD5 -> PD6 which one is the most stable and without too much bloatware and has the current security updates??
[AT&T Samsung Galaxy S6] ¿Will-it-Blend?:
May security patches of course. Also there is a new 'Google" option in settings. Same ole AT&T bloat (no direct TV) still checking stuff.
[AT&T Samsung Galaxy S6] iceman4357:
A few people are currently looking into PD5 vs PD6. Right now it looks like all versions have similar bloat. Will-it-bend is being nice enough to flash PD5, review, then flash PD6 to see what the differences are.

A lot of people have said PD5 has been a great fast build. PD6 is about 200MB more, but we are awaiting a few people to comment back to see if there is additional apps or what are the main differences. A few had mentioned that the modem is different, but 200MB seems extreme just for a modem.

I would say you can flash wither PD5 or PD6 and be happy with either.
[AT&T Samsung Galaxy S6] mnp261194:
Can I go from PD3 to PD4 or i have to go back to OJ9 and then to PD5 cause i'm currently at PD3

Is there is anyway i can i can get the OTA without a sim card? and without odin? (whan it comes)
[AT&T Samsung Galaxy S6] iceman4357:
I believe there was another memeber who went from PD3 -> PD4 -> then PD5.
[AT&T Samsung Galaxy S6] ¿Will-it-Blend?:
Okay so without a change log in have no idea what's different. Don't even see much difference in PD6 compared to PC2 besides the security patch and performance improvements. 202MB but no extra bloat either.
[AT&T Samsung Galaxy S6] sand_bit:
I've just installed PD6 from PD5, there doesn't seem to be any extra bloat.

I've written up a guide here:

[AT&T Samsung Galaxy S6] Red5:
Is there a straight ota for OJ9 to PD5, or even OJ9 to PD6? If so, we might be looking at the final build.

I remember back in the Captivate days, that even though we found some slight newer builds, the official that they ended up pushing out was one or two versions behind (the consensus was they kept messing with the rom and broke more, so they pushed out what worked compared to the newest revision).
[AT&T Samsung Galaxy S6] Dante087:
There is nothing from at&t to go from PD3 to PD4 then PD5... The only way is to Odin back to OJ7 then update to OJ9 then adb to PD5 then PD5 to Pd6

Posted this in the other thread as well, there is an upgrade path from PC2 to PD6:

There's a PC2->PD4 upgrade here: https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPC2-to-U3CPD4

From there, should be doable to do PD4->PD5 with https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPD4-to-U3CPD5-UP

And finally, PD5->PD6 with https://xdmd.sl.attcompute.com/agents/48653/1488/SS-G920AUCU3CPD5-to-U3CPD6-UP

Also, no need to add .zip. ADB automatically assumes it's a zip and throws an error if it can't unzip it.

Note: I just found these files, trying to flash now to PD4
