I received OTA update for android 6.0 in my spice dream uno. After I upgraded to 6.0 it started to face severe battery drain problems. My phone is unrooted. I need to know the method to downgrade it to 5.1.1. Thanks in advance.

Is there a way to downgrade without rooting?

Nope.
It's easy to root and flash back stock rom. Just follow the guide and use Android ONE Toolkit to root and flash recovery.

try this
Tried to update to rooted MM from rooted 5.0 with dev bootloader. Long story short, I lost root and am now on PD1, with PD1 bootloader. I installed the NK2 kernel to try and re-root, but the phone just hangs on the Samsung screen. I have tried Odining back the whole OS to Nk2, and Odin keeps giving me a "FAIL" message.. The only OS that seems to flash without failing is PD1. Any thoughts? Any help/insight would be greatly appreciated. THank you in advance.

I don't think that will help me. I want to root. Unless things have changed, I need to roll back to NK2.

I am pretty much resigning myself that I am going to be stuck on PD1, unrooted.. I am having trouble downloading the file, and when it does work, it is SLOOW, so maybe tomorrow I can give it one last try.

I was also unable to flash the entire NK2 firmware. And yes I am crazy.
I was wondering if I could possibly downgrade back to android 4.3 on my gt-i9500 by just flashing the stock firmware using odin. I'm currently on stock rooted TouchWiz firmware android 5.0.1.
And if there is a TWRP flashable stock android 4.3 ROM, kindly tell me.
Your help would be highly appreciated.
Thanks.

The only TWRP flashable stock ROMs are custom TouchWiz based ROMs.

I heard that, when trying to flash older firmware than the one on your device, Odin fails due to some downgrade restrictions.
Wit that being said, it's not impossible to downgrade. You just have to workaround those restrictions. Maybe by following a guide.
I am Official Nougat. Currently locked bootloader and stock. im thinking about installing a 6.0.1 custom rom. Do i need to downgrade first or can i install directly 6.0.1 rom from android N .
Thanks in advance
The rom itself will work,however fingerprint and camera might be borked.

If you don't use the fp ,the rom will work fine without the downgrade.
Thank u everyone for the replies
Oreo has been released for the Canadian SM-G935W8 and prior to upgrading im curious if anyone has been able to root it
Im running a rooted version of 7 and don't want to upgrade if I lose root
I looked on XDA and various forums but cant seem to get a definite answer
Anyone?

Yeah I CANT seem to find a stable answer anywhere!
I ODIN flashed stock Oreo (lost root) after some issues installing un-stable ROM's cause I wanted Oreo earlier lol
I assumed it would be as normal steps?
1. Odin flash TWRP
2.Reboot recovery and flash no-verity-opt-encrypt-6.0.zip & Magisk.zip
3.Flash ROM via TWRP????
Best of luck, hope someone reads this thread.
