Downgrade S7 Edge to Marshmallow - Samsung Galaxy S7 Edge Questions and Answers

Hi, I know this isn't the right forum but I can't publish in another one.
I have a SM-G935F (Exynos), and I don't like Nougat's battery life. So I wanna downgrade to marshmallow. But when I was looking how do that sometimes I had read I need to delete all Google accounts, restore the device, turn off the device, and then do wipe data/factory reset and wipe data cache and turn off again the device, to finally go to the download mode. But I too had read I only turn off the device and put the download mode.
Do I have to do all those things or do the second one?
I don't want to brick my phone.

Downgrading to a previous version might corrupt your IMEI stopping your phone from making and receiving calls, I've learned that the hard way..So better do a thorough research before taking any action.

I too don't like Nougat which makes me go back again and again to a Marshmallow build. I haven't experienced any problem going back to MM from Nougat. I just have to factory reset every time to boot up normally after flashing the MM Rom via Odin. I currently have this build on my phone with Xposed:

i have downgraded my grand 2, s7 edge W8 model multiple times. all i do is shut off the phone put it in download mode, open odin select proper files n then simply flash. note i never changed any odin settings just simply choose the right files.
i have done this with both stock n custom rom installed. never had any issues
also y not try a custom 7.0 rom. batman rom is quite good, well so is ambasadii one. haven't tried any other rom so can't say anything about others.

I Also prefer MM to N by far in terms of battery life. Never had any issues downgrading to MM from N using Odin, no special things to do other than going into download mode and flashing the MM firmware.
Only reason i had to go back to Nougat is that the carrier will cut LTE for MM starting from today (due to signal improvement processes that are not compatible with 6.0.1).
I may consider Flashing back MM and keeping the Modem from Nougat if that works.

I downgraded to Marshmallow and athough it does't seems, the battery life is a lot better in 6.0.1.
I do not like the old Emojis, but i can handle it
Howhever, the performance increases too. I'm so happy with Marshmallow.

DRA9 BASEBAND FIRmware?

I have SM-G930A, I think with a locked bootloader.
Currently I'm on Marshmallow and when I try to update using system update it says your device is up to date. So If I flash Nougat using Odin will I be able to downgrade back to Marshmallow If I don't like Nougat ?
Thanks

downgrade official lollipop to official kitkat 4.4?

Has anyone successfully downgrade official lollipop 5.0 to official kitkat 4.4? How? Is it safe to do it? Please help [emoji38]
I am quite sure a lot of people have gone back to KitKat from Lollipop, including me. In the course of last one week I have flashed Lollipop at least six times and came back to KK each time. So yes, downgrading is absolutely problem free.
Thank you devil

I would save all your personal data to the PC desktop. Wipe everything ( twice ), and then do a factory reset. Now odin flash back to whatever version of KK OS you want to run. Make sure you use a complete stock .tar firmware ( system/modem/bootloader ) from xda or sammoblie has them. Once you flash back to stock, odin flash it again to make sure everything installs. Then root and reinstall your data. If you do a lot of flashing from lollipop to KK, your going to have to take out the trash every once in while for lack of better words. I do a lot of flashing and end going back to bone stock about once a week, this helps from corrupting vital programs like efs. So in other words there is no magic pill. For more info click my signature the versions of KK might be different but the procedure is the same.

Downgrading official lollipop (XEO) to Kitkat (BTU)
Hello Note 3 users. I would like to ask (maybe someone already tried) to downgrade official (not leaked one with bugs as was mentioned) lollipop to kitkat? My phone originally had BTU kitkat, but I wanted to test lollipop and downloaded one from sammobile (XEO). Flashed as it was described in Sammobile website, everything went well. Rom is working well, but gps takes ages to fix, and only a few satellites. They are always lost while driving. Because of this reason I would like to come back to BTU kitkat again (get gps working normally again and receive future OTA updates). Can I flash Kitkat like it's described in sammobile? Wouldn't I mess the bootloader or something? (XEO Lollipop to BTU Kitkat)
I successfully downgraded from Samsung's official 5.0 to 4.4.2. I wiped the phone first in recovery. Then flashed using Odin version 3.09.
My Note 3 is an SM-N9005.
After receiving the 5.0 update yesterday for my Note 3 (product code XSI) and not liking it very much I will be downgrading again. At least the newer build in the XSI ROM seems more stable than the BTU ROM I tried before but I will still downgrade. One of my favourite apps, Delayed Lock, isn't working on 5.0.

[Q] How to update to 5.0.1

Hi,
Im from the netherlands and noticed that the update for 5.0.1 is available.
I have the Exynos (N910C) version android 4.4.4 rooted installed now.
I have changed dpi settings true xposed.
What is the best way to update to the new version 5.0.1 ?
Thanks,
Roy
I have used the auto root to root the stock rom.
N910C is Exynos, not Snapdragon, so choose your ROM carefully.
Best way to upgrade is to backup everything first, then install new ROM with Odin (download correct version from sammobile), then root using your method of choice (I personally recommend flashing TWRP recovery and choose root on exit).
After that, you can restore everything you need from the backups.

Your device was rooted and no way to upgrade 5.0.1 via OTA. The only way now is download latest Firmware (for your Area) on Sammobile.com or similar website then using Odin to upgrade. Remember: full wipe on recovery first then flashing FW via Odin on Downloadmod.
Thanks for the awnsers. i meant the Exynos, sorry for that.
I havent tryed to update it true normal update way becouse i thought this wasnt possible as my device is rooted.
So i might try if i can do this?
Roy
OTA will fail because you tripped Knox when you rooted.
Besides, lollipop brings a new bootloader, modem and csc, so even if you choose to flash a custom lollipop ROM, you still need to upgrade those using Odin.

My device was imported from hungary and i found this one on sammobile :

does this also incule the new bootloader, modem and csc ?

Yes, it seems ok.

thanks,
I have installed the 5.0.1 version true odin without doing a full wipe. I still have all my apps and files and it seems to work oke.
Did i have to do a full because of the battery draining stuff? or is it oke like this?
Roy
Should be fine as it is, but a full wipe once in a while never hurts...
If you notice something wrong, battery drain, lag or even applications force-close, then why not... perform a full wipe and restore your apps and settings gradually.
Make sure you backup everything, i failed my stock update to android 5..0.1 (OTA), and now i still didnt found anyway to get my data back, it remains dead there

Downgrade to MM from N for better battery life?

I am using exynos on N. Was getting ~6 hours SOT on MM, phone would last almost 2 days. After flashing nougat, only getting around 2-3 SOT and phone doesn't even last 1 day.
I am:
-not using any package disablers
-not using AOD
-I would say even usage of wifi/data
-all motion detection off, not very many apps doing background syncing (or so I think)
I have owned this phone for almost 1 year now, always fast charging everyday so my battery is probably very weak by now.
Should I:
1. Try flashing a custom debloated N ROM? (I've had people on here tell me they used ton of different N ROMs for months and they still went back to MM for longer battery life.)
2. Try flashing a custom debloated MM ROM?
3. Pay ~$70-80 to get a new battery?
For example I am considering flashing superman rom but not sure if I should flash mm or N.
I don't know how people are getting 8-9 hours SOT on nougat. If anyone could give advice that would be great.
Thank you.
Hi,
Since you're charging the phone everyday with fast charge and is using it for almost a year, then you have to keep in mind that the battery won't last as long as when you got the device.
You can however try to get around the aging of the phone by making use of less bloated ROMs and more battery efficient kernels, if you're not using Knox featured neither is using Samsung Pay, then since you're at the end of your warranty I highly recommend installing a custom ROM.
I do not think that the downgrade is a good solution, first because you won't be able to do it AFAIK, Samsung Knox prevents a system downgrade ever since the S4 IIRC. So unless you get a custom Marshmallow ROM that works for your current Nougat bootloader (which isn't impossible, I think most should run).
Personally in your situation I'd first try a clean stock install, if the problem persists I'd go for a Nougat ROM, because since you are installing a custom ROM, why not go for the latest and greatest instead of downgrading since you can get a good battery life on the Nougat ROM as well?
All the best,

I'm as well having poorer battery life on Nougat than I had with MM, though 2-3 hours SOT seems to be too low.
On Nougat I get 5 hours SOT, while on MM 7 hours were the norm. Hopefully Sammy will release some update "soon" (lol, ok: somewhen...)
Anyway, what do you mean by downgrade not possible?
What happens when I flash a stock MM Rom through ODIN now, won't that work?
Downgrading to MM from Nougat works just fine by flashing official MM Rom via Odin.
I did it on my G935F because I'm using xposed which is not yet working in Nougat.
Hi,
Good to know that downgrade is still a possibility, I've read on another thread (don't remember where or when tho) that some users reported having Odin simply failing to flash a downgrade (IIRC was S6 MM downgrade to LP). Sorry for the misinformation .
All the best,

It's really up to the phone's owner to decide. One can only suggest but everyone has its own reasons to choose either N or MM.
One thing i noticed during the downgrade, it's asking for your Google password so be sure to know it. It may also cause your phone to freeze during boot up, the solution for this is to go to Recovery and wipe data/factory reset and wipe cache. So be sure to backup first your data by using TB or synchronisation thru your Google acct or Samsung acct.
Also because S7 snd S7e have no removable batteries, be sure you know how to go to Download or Recovery mode without first turning off the phone.

Ok thanks
If doing a downgrade I would strongly recommend a factory resets as you may encounter a problem anytime since there's no downgrade migration.
Though everyone can decide by his own you should keep in mind you won't get any further security updates for Marshmallow from Samsung. In such case it may be better to go for a custom Marshmallow ROM which is still maintained (if available).
The battery management on Nougat is definitely better than on Marshmallow. You may search for the reasons of your problems...
It's not difficult to change the battery. There are some good step by step online manuals on youtube.

s7 edge screen resolution

Hello I recently updated my galaxy s7 edge to nougat and it couldn't read sim anymore all I got was "emergency calls only" a friend of mine helped he rooted it and downgraded it to marshmallow, now I am stuck on marshmallow I can no longer get OTA updates which means I can't change my screen resolution anymore coz this function seems to be in nougat only any help xda saviours??
why did you get that error in the first place? ?
download a nougat rom from http://sammobile.com and flash it on your device.
take note that you must only download the rom for your particular model. for example if you own a g935f, don't flash a g935fd rom.
