Help to DOWNGRADE from 7 to 5.1.1. Lollipop - Galaxy S6 Edge+ Q&A, Help & Troubleshooting

For many reasons, I want to get my original 5.1.1 software back on my Galaxy S6 Plus NEE region, but nowhere can I find the right ROM for this phone. The exact compilation is: G928FXXUCQF3
IF YOU CAN HELP ME TO FIND IT.
The other problem is my commitment to this risky procedure not to brighten the phone. Wherever I found ROM all are one file: G928FXXS3BQA9_G928FNEE3BPI1_G928FXXU3BQA5_HOME.tar.md5
My question is can I install ROM from another region - Bulgaria on my phone or is not it possible?

you can downgrade to 5.1.1
its pretty complicated and has its ups and downs but it can be done. Made a guide about it here if you wanna try

[Q] Can I upgrade to 4.4?

So when I first got my note I imediately used this guide to flash kitkat and completely ****ed it up, it just stuck on the Samsung n9005 screen.
This was a link to C4ETech's video called "Galaxy Note 3 - Samsung Official Kitkat 4.4.2 - How to Flash/Install" but I had to remove it.
I assumed it was something to do with the CSC code (mine being BTU) so I installed a BTU rom using this guide.
This was a link to TheSmokingAndroid's video called "HOW TO UNBRICK & UNROOT SAMSUNG GALAXY NOTE 3" but I had to remove it.
Now I want to install a kitkat rom preferably a stock one but there isn't one for BTU. So I looked at the custom roms as some support BTU but require the device to be on 4.4 already. How can I get onto 4.4 if every 4.4 rom requires a 4.4 phone? Will I have to wait until an official BTU update comes out?
I've attached a screenshot of my About Phone page (which doesn't have BTU anywhere, I don't get it).
I probably have the complete wrong end of the stick so sorry for wasting everyone's time but if you have a minute to help I'd really appreciate it.

Try *#1234# might come up there. Anyways, go over to Sammobile and grab any of the latest 4.4.2 KitKat ROMs for your device (9005) as you said. And it should work fine.
Advice: Wipe your phone, not compulsory but advisable. Cheers!
I have a canadian variant note 3 900w8 and i want to flash 4.4.2 as well but i was hoping to flash the t-mobile version as i have heard of issues with the 9005 rom compatibility, just wondering if anyone has had experience yet, or if it has been done.

Thanks for your help but I've already done that and the newest version I can get is 4.3 I'll just wait until my phone gets the update, Thanks anyway
I've managed to get onto 4.4 now by flashing a polish ROM after reading that they support BTU, I don't know how to delete this thread so I'm just letting everyone know my issue is resolved

If you want the ability to flash back to 4.3 from 4.4, install custom recovery and roms and keep your Knox 0x0, head over here and do some reading ( if you haven't been there already ).

[Q] How to signal lollipop 5.0.1

Hey all
I am unfortunate to have the UK N910F phone (PDAN910FXXU1ANK6 and CSCN910FH3G1ANK1) as this has not received the lollipop update. I have not rooted the phone and don't really want to root as some apps will not work with root I. E. Banking apps.
My question is there a international Rom that I could flash with Odin as I tried a lollipop rom with the wrong PDA and CSC (PDA N910FXXU1BOC3 CSC N910FVFG1BOC2) and that just bricked the phone, luckily samfirmawre had my original 4.4.4 Rom so my phone is OK
Many Thanks
Alexndr's BOC3 ROM will allow you to keep your current CSC:

Yet another person not to bothered about reading forum rules.
Answering your question. There is German soft for n910f on sammobile. I flashed it via odin and it works just fine.
Be careful
About your question, be careful with that, if you have your phone from a carrier (including if you unlocked it), be careful because, for example, here in Spain if you have your phone with Vodafone and you change the ROM to a non-VF, you may notice that your payment by NFC won't work. BTW I works with some banks in europe and I had no problem with whatever o their apps changing the ROM to a official from another country (nor to a custom rom, but that's your choice), now I have your same model, bought unlocked to samsung with the indian ROM from sammobile

question regarding 910c stock rom

I am on sammobile trying to figure out which rom I need to download for the 910c that is english (US). Which one should I use?
Well most roms are in english and have no carrier logo or anything in the firmware download section for 910c, Click where it says select country Choose any firmware From Poland, Pakistan or United arab emirates these will have no carrier bloat ware and are in english. (beware don't update to COJ5 BUILD it has a locked bootloader if you update to 5.1.1 COJ5 there is no going back to 5.0.2 or 4.4.4) use firmwares below COJ5 build if you dont want to be stuck on the latest firmware.

Thanks, and actually I already updated to it without realizing it was locked, which is why I am looking at the stock firmware. Sweetrom was constantly freezing and then going into endless boot. Not sure if I need to replace the kernal to fix that, but I figure I would at least try from scratch.
Today was a learning experience. Have been flashing for years. The one time I decide to update without researching it better I was bit. I know better now. Should have stayed on v14.

**Updating the Firmware Samsung Galaxy S5 SM-G900F**

Ok so here's my dilemma:
I have searched and searched for about 4 straight days on what to do and can't seem to pinpoint the procedure I need to enforce. This is my first posting by the way, and I'm kind of a noob to all of this stuff, but extremely intrigued by it all, that I can't seem to put my phone or laptop away as long as I have the free time to do more research.
I just recently rooted my Samsung Galaxy S5 variant G900F (was extremely excited that it was a success on my first try!). I just purchased this device in July (and it came unlocked as far as to using whichever carrier I wanted). Now, what I'm looking to do is update my firmware (from what I've gathered, I believe I need to do that in order to install a custom ROM? If I'm wrong, please correct me). So my device information is as follows:
MODEL: SM-G900F
PRODUCT NAME: kltexx
PRODUCT CODE: SM-G900FZWAMRU
PDA: G900FXXS1CQD8
CSC: G900FOJP1CQB1
BASEBAND: G900FXXU1CQB1
BOOTLOADER: G900FXXS1CQD8
BUILDNUMBER: MMB29M.G900FXXS1CQD8
ANDROID VERSION: 6.0.1
KERNEL VERSION: 3.4.0-10662519
GPU: Qualcomm Adreno (TM) 330
MODEM: MSM8974PRO
I don't know what other information someone would need in order to help point me in the right direction of what I need to do, but it would be greatly appreciated! If you need any other information, let me know! I can't seem to tell which region this device is typically set up for (as I said, I'm a noob) so if someone can explain that a little, that would be wonderful too. Thank you so much!!

Hi,
Your case seems to be llike somebody comes to a shop asking the shop assistant: "I want to buy something but I don't know what"
But now to be serious - in order to help you, you need to specify what you really want to achieve because from what you wrote I am not sure.
You have SM-G900F phone with latest MM 6.0.1 firmware for Mauritus (MRU) region. So you should be good to go.
If you just want to play with your phone, then OK but you should be aware that when you root your phone or flash any of the custom firmware you will loose your warranty. You wrote that you are rooted already so that is it -> KNOX flag is set 0x1. But if you bought a used phone then you should bother too much with that (warranty doesn't matter).
To flash any of the compatible custom roms you usually need a custom recovery (for example TWRP) and you are free to flash custom roms (following OP instructions of course).
That's it for the beginning

Thank you! Well my initial goal was to install a custom rom but couldn't seem to find one that included my build number, so was a little confused. There's many to choose from, but I can't just download any of them. Or does a specified build number not convenient?
I have the TWRP downloaded, for some reason I thought I needed to update my firmware since I didn't see it anywhere as far as roms went. I'm mostly experimenting right now. I looked into rooting for 4 months before I finally did it. And now I'm overwhelmed with excitement of all the things I can do, that I don't know where to start! So I thought a different ROM would be a good start. I really enjoy customizing my phone and making it as unique as possible, any suggestions as far as which ROM I can do?

Well, now I know a little bit more. You are on the latest stock rom foreseen for your region. So you are good to go for any customization. To flash a custom rom you need a custom recovery. when you are already rooted the easiest way is to install TWRP app from the Play store:
https://play.google.com/store/apps/details?id=me.twrp.twrpapp
and flash the recovery.
Before flashing any custom rom it is highly recommended to do nandroid backup from TWRP (backup of all important partitions of your phone).
Then you can try a custom rom. Check this subforum:
https://forum.xda-developers.com/galaxy-s5/development
or this:
https://forum.xda-developers.com/galaxy-s5/unified-development
and find a rom of your choice. Read carefully the OP (compatibility, features, issues) and decide.
You might start with LineageOS based on android 7.X Nougat. But be aware that custom roms might have some bugs and are based on pure android sources so they will give you pure android experience. Some might love it but some are disappointed
