Downgrade nougat? - Galaxy S6 Edge Q&A, Help & Troubleshooting

So I'm still on 6.0.1 and I want to update to nougat but I've heard lots and lots of complaints about it running bad on the s6 so I'm wondering if I update to nougat and don't like it can i go back to marshmallow? If it matters my phone model is an sm-g925w8.

Hi! Do you have a rooted phone with a recovery? Go to the recovery and make a backup. If you don't like Nougat you'll simply restore your backup using the recovery.

You can also downgrade by flashing a 4part firmware via Odin. I tried it myself.

What do you mean by 4 part firmware?

I am rooted and have twrp installed. Backing up everything in twrp and restoring it will downgrade back to nougat?

Stock recovery question

So I probably should of asked this before flashing but anyways, I flashed CWM to my tablet and I am about to flash aokp to it but I was wondering if I was going to go to back to complete stock again does it matter what stock 3.2 recovery I use to get official updates? I did make a nandroid backup so I am not to worried about getting a stock OS but its just the stock recovery that bothers me.
For the record I have a Canadian WIFI 16 gig tablet.
Official updates...? Odin is the only official update you need! :] Just so you know, you can't completely revert to stock unless it's for that specific firmware, only way to do that is by a clean flash to avoid all the un-necessary bricks and such.
Nandroid backup does not exist on stock and last I checked the recovery and CWM do the same job of "Applying update.zip" so it shouldn't matter, it's the firmware's regional value that matters, not the recovery.
So if I were to do a restore of my nandroid backup (from CWM) then that means that I would be able to get the notice that I would be able to update to the latest official firmware from Samsung no problem?
As long as you don't use Cus ROM's then yes.

[Q] Restore 4.4.2 TWRP Backup to G900TUVU1DOB?

I upgraded to LP by Odin flash G900TUVU1DOB1 and then installed [ROM]ViSiON-X US TMO[Android L 5.0][G900TUVU1DOB1] Phone is working fine.
I'd like to revert to my former 4.4.2 "Xtreme Dynamic Kat 1.1" It is a Safestrap AT&T rom that ran on 900T but is flashed without Safestrap and TWRP on 900T.
Would it be ok to just restore my 4.4.2 TWRP backup? Do I have to Odin back to 4.4.2 Firmware first? I don't want to do that and lose Internal Storage or the ability to easily go back and forth between roms .
My first thought is no. I can't restore a 4.4.2 rom over the LP bootloader but I really don't know.

Red Honor Bootlogo & Marshmallow Update Questions

Hello there I have a couple questions regarding to the red honor boot logo and also on how to update from a stock rom with TWRP and root ( also a couple of system modifications ) to the new B331 update.
So heres the rundown, when I first got my honor 5x I did not spend too much time on the stock rom I went ahead and rooted my phone and installed TWRP then made a backup of my stock rom (B151) no modifications other than SuperSU being installed. After that I went ahead and installed CM13 nightlies and updated mostly everyday up until the build July-18-16. I had adoptable storage enabled with my 32GB SD card and I totally forgot to disable the adoptable option before I reverted to my stock backup so when I went onto TWRP and tried to restore my backup I always got an error where it said something along the lines " error; could not find system" but instead of it backing out it continued to restore and bricked my phone. I had a somewhat clever idea to flash any build of CM13 I had on my computer and guess what it booted then I disabled the adoptable storage and booted back onto TWRP restored my backup and everything was fine until it booted and I noticed the honor boot logo had a red "h". I found that weird since I have restored my backup previously and that never happened. Anyone knows what it could mean and how to fix it?
My second question is how should I go about updating to B331? Should I download the stock recovery B151 ( since that is what shipped with my phone and is what my backup is) then revert to my near stock backup, flash stock recovery and unroot then update through cslA's B331 instructions? Or should I somehow fix the red honor boot logo then go ahead with what I stated above or is this all done differently? I am not a newbie at these kind of things I just moved onto more important things in life and simply want to update my phone. My needs for flashing new roms daily are over and I just simply like huawei's UI as it just "works" for me. Thanks to anyone who responds anything is appreciated as I can't seem to get my old skills working again. Haha:laugh:
Fibgerprint aint working right? U cant go back to stock with just a normal twrp backup. Install an update.app through dload for your region and then apply the twrp backup.. Make sure you are on B151 Recovery!

No, my fingerprint is working... I just wanted to go back to stock ROM with root and that's what I got just now I have a red honor bootlogo. Now I want to update to marshmallow but I have a fear that even if I follow the steps onto reverting to stock I may brick it because of the red bootlogo.
So what you are saying is I should download my B151 recovery and firmware to revert to stock then update and from there I should root and install TWRP?

Should I update 10d (rooted)

Hi, I saw about the quad rooter issue, and today I checked the ota update. (I never had an ota update because I always been rooted, s3, s5 and g5)
But now it purpose the 10d update. (450mo)
I'm 10c h850 rooted.
Should I make this update?
Will I lose root? (Rooted via twrp super su)
If I have to re install everything (apps, datas, root), maybe should I wait for 7 nougat don't you think?
Thanks.

It won't install the update anyway with twrp installed. It'll just fail and reboot. Wait until your ROM devs rebase your ROM on the new base.
Thanks, it was stock rom. But yeah I don't think it's worth if I make a fresh install with android 7.
As you said I'm affraid about the bootloop issue.

Not bootloop, just because you have custom recovery installed the stock update process will not complete even on stock Rom, you'd need to wait for a flashable version of the update or you'd have to flash stock recovery back to your device first.
I just used LGUP without any issues. Pretty painless.
Then flashed TWRP again, and flashed my ROM of choice.
The only tricky part was quickly getting into TWRP after you flash TWRP. It reboots and if you're not quick enough, TWRP will be overridden by the stock recovery. Then you just need to repeat (flash TWRP again, get into TWRP and flash ROM).

Need a few questions answered to getting to stock and then custom ROM

I'm confused on a few things,
I once had Cyanogenmod with Marshmellow, after updating to an OTA Cyanogen version I got stuck into bootloop and for some reason I couldn't get back to Cyanogenmod in TWRP recovery and the only nandroid backup was B331 which is only Lollipop Stock which i'm currently on. Now I just want to start from scratch and get back to latest Cyanogenmod with Marshmellow. Where do I start? I have Current Build KIW-L24C567B331 that is currently Lollipop and I wiped my internal SD. When I try and look for Stock OTA updates it says no updates, the update client has NEVER worked on this phone. I have currently TWRP recovery on it. Do I have to go to a certain build to get back to Marshmellow? then go to Marshmellow Stock then to Cyanogenmod?
I tried following this guide: http://forum.xda-developers.com/honor-5x/how-to/guide-kiw-l24-to-stock-t3318268 but I don't understand which stock I should go to and the instructions aren't very clear (maybe i'm just dumb)
Another question: for each Custom ROM I install do I go back to a certain stock build then flash the custom ROM?
Much help appreciated,
Thanks
Are you in stock Marshmallow before you flashed CM?
Sent from my honor 5X using XDA Labs
if you are saying that you have twrp, with lollipop emui on, due to twrp, you will never get any update,
since you want marshmallow, i think you need to be upgraded to marshmallow firmware,
to do so, you need to download the marshmallow build, generally the b331 firmware in the link you provided...(dated:10/07/2016)
go ahead and download that firmware and follow the procedure, in the end, you will be left with the marshmallow emui build with stock recovery on (eligible for ota and warranty )...
now, since your bootloader is still unlocked(i guess), you can reboot to bootloader and fastboot twrp recovery(latest twrp is recomended)..
and now, you are pretty much good to go.... download latest cm13 nightly and install... enjoy
please do perform the steps carefully:good:
AND NO, YOU DO NOT NEED TO GO BACK TO A STOCK BUILD TO FLASH CERTAIN CUSTOM ROMS
