Hi

I am on pie and want to downgrade to Nougat because of horrible battery life. Does anyone know if it is possible easily via LG UP & Uppercut and giving it the .kdz file or do I need to have the dev version of LG UP?

I am asking this because I read somewhere that pie will upgrade the policies and downgrading from pie won't be easy/possible. It would brick the phone. I know to downgrade from oreo is easy but does anyone have an idea of downgrading from pie?

There are some links which i am placing down here in case of reference.

[Downgrading from Pie BETA to Oreo](https://forum.xda-developers.com/v20/help/lg-v20-f800l-how-to-downgrade-pie-beta-t3971971) (i am not on beta, i am on final release version or whatever it is called).

I tried checking my ARB using this code \*#\*#244773825625#\*#\* and my status is:

APPSBL(LK) 0 SBL1 0 TZ 0 RPM 0

I have F800K.

By "dev version", are you referring to the modified one that allows you to upgrade and downgrade with no issues? I believe it has the modified .dll.

Yes you need the dev one to downgrade from the pie.
Can you please please point the dev version of LG UP post because I tried finding in the forum and found different ones.

And I believe the rest of the steps for the downgrade are similar as to upgrade, there is no complicated process involved. Am I right?

Try searching LGUP DUAL MODE. It should on be on the top of the list..
For me (f800l) the step sometimes a little bit not standard. But it could be different from your device. Try that lgup dual mode first.
