G928A firmware downgrade? - AT&T Samsung Galaxy S6 Edge+

I'd firstly like to state I am new to the forums, and give my thanks to brilliant people who give guys like me somewhere to turn. Now, my question is, is it possible to downgrade from MM PJ1 to OGG or OJ1 or lollipop in general. I've seen a similiar thread about a UAE version or somethung that said it was possible. I have successfully downgraded a Note 3 from lollipop to kitkat, which has locked bootloader too if I'm correct..?, but I would like to have any input before I do this as it is my main phone. Thanks!

yes it is possible.

So in theory, i could downgrade to Lollipop and use the kernal auto-root to possibly get rotot? I just got an HTC 10 so I'm really itching to mess around with that s6 Edge Plus. Lol.

Tmobile G3 Marsh 6.0 update?

So I been using my G3 since it came out, and I see a lot of other phones are already got the Marshmellow 6.0 update, except the Tmobile G3.
So is there anyways I can update my Tmobile G3 to Marshmellow 6.0 right now? Instead of waiting forever for Tmobile to release it? Any help would be appreciated, thx.

Yes. You can install a custom ROM like this one: http://forum.xda-developers.com/tmobile-lg-g3/development/rom-1-11-15-t3000137
If you are asking a question like this, I think it's safe to assume you haven't done something like this before (or often). I would HIGHLY suggest you do some reading before starting to mod your expensive smart phone. Always double check every file before flashing, as one mistake can leave you with a very expensive paper weight.
Flash this

Flash what? that link just go to the main forums?
What is the best ROM for Tmobile G3 atm? thx
If you are looking for official LG 6.0.1, this is the best ROM in my opinion. It supports all variants including T-Mobile.

Flashing with different region firmware.

Hi guys, I have Galaxy Note 10.1 SM-P605. My one is most likely a Malaysian variant. Baseband version: P605XXUCOE1. I still haven't got the lollipop update on this variant. Now kinda planning to flash it with the Finland version. So I have some questions here before I do...
1. Will there be any sort of problem because of different baseband/ region?
2. Will I have to face any issue with knox or official OTA updates in future?
Thanks in advance.= :fingers-crossed:
I can only answer half of your questions, as my device is rooted, so i don't get official updates anyway. Flashing a different region firmware never caused me any troubles, not on my 10.1, or my Galaxy Note4, so it won't affect the functionality of your device.
As for Knox, it will trip Knox as you are flashing a kernel not for the same region...
It may just bootloop. Make sure you have a stock rom to go back to, mind you this may not work if the bootloader is upgraded to a newer version, say KK to L or L to MM....

Ya after first flash I went through bootloop, after the second one it was fine. Now enjoying Lollipop on my tablet.

Glad to know man, btw I am having only 1 problem that is it's not showing my operator's name on lock screen or in connection settings, instead it's showing the 5 digit number code of my operator. Thats not a major issue I guess, must be some conflict with regions.

Really, you can find any info about how to update in this forum? If you can't i think you should stay on firmware you are now.

Dude, Ive tried everything the threads have said to do, its not working, tried samsung support, and the were useless. tried auto root that just sent me into bootloop. Im no super tech guy, but i had no trouble at all rooting or updating firmware on my s4, or s5. i read something about there not being much support for the s6 edge plus g928a because it was just a bridge to the s7. if you know of a working update please share, if not im kewl with that to.

How do I downgrade From 7.0 to 6.0.1??

I need to root me S& active and it does not look like 7.0 will be able to be rooted anytime soon.... so is there anyway I can revert back to 6.0.1 my phone is new and has 7.0 on it (just purchased 2 weeks ago) So I am assuming I need to flash the whole PK2 firmware... does anyone know where a link is to the full download to it?
Edit, heres the mirror to get from 7.0 back to 6.0.1
Confirmed working, and was able to switch from 7.0 back to 6.0.1 then back to 7.0 and then back to 6.0.1
Found this one G891AUCS2API2_CL8737252_QB10881022_REV02_user_low_ship_MULTI_CERT.rar here

edit: Correct password above, file now working correctly
edit: Correct password above, file now working correctly
Its 7.0 not 6.0
this isnt 6.0.1
Has anyone found the 6.0.1 firmware for this phone? I can't seem to find it anywhere.
I also really need this firmware as i'm bricked, Every link I can find has failed me. It seems to have either expired or been removed.

Do you know if it will brick if I downgrade the firmware? Its on Nougat and dont want to risk having a paper weight.
I'm currently testing this one. Got S7 Active on 7.0 trying to downgrade to 6.0.1 to root. Link I have posted above was pointing to 6.0.1 firmware. First attempt to downgrade failed so far. S7 Active survived so far.
I'll be testing further after work.

Hi. I'm back. Took me a while, like 3 hours to get this one right, but I have managed to root S7 Active on Android 7.0 by following guide from the Russian site. I'd help if anyone is willing to root on 7.0
i had already put up tutorial, and links for Root on 7 here...
https://forum.xda-developers.com/s7-active/development/rom-mod-release-t3635879
also a nice script to debloat, and add s8 mods too ...
(its also where your QD4 odin file originated, look in the root of the rar file )

Can I flash 5.1.1 phone down to 4.4.4?

Can I downgrade 5.1.1 to 4.4.4 is original ROM still available and would it affect anything like Knox? Or it's the same crap with locked BT and it would remain from 5.1.1? I don't plan any rooting just plain OEM stuff.
Ok there is life in Note II threads, but Note 4 is still one model behind the flagship...
Sadly this thread is also dead...
