Downgrade to OOS 4.5.1 from OS 5.0 using TWRP

[rebelpixel]

OOS 5.0 (Oreo) seems to have a few hiccups, most notably lower battery life, and many are reverting back to OOS 4.5.1.

For those who've tried to downgrade to 4.5.1, can it be done without wiping internal storage? I'm trying to avoid this because I don't want to copy close to 100GB of files back to my phone as it's very time-consuming.

I use Titanium Backup so I'm not worried about app data too much. I'm currently rooted with Magisk and would like to go back to the same rooted setup on 4.5.1. I'm also on blu_spark/eng.stk's oreo-compatible TWRP right now.

Unless you backup your 4.5.1 with the same twrp you are using right now, there might be a risk.
but you already have backup, right ? the worst thing is having to wait for those 100GB data to be copied back to your phone, rather than loosing everything.

I actually didn't bother doing a nandroid backup of my 4.5.1 partitions, all I did before upgrading to oreo was:

- titanium backup of all apps
- copy all of /sdcard to an external disk

I'm just considering what would be the shortest path to going back to 4.5.1.

What would be great though is if Oneplus releases the next version of stable Oreo that fixes the battery drain and the other issues that people have encountered.

I don't know why the peoples are complaining high battery drain in oxygen os 5.0. Peoples also complaint about VOLTE issues but I am using it without any issue. Perhaps they don't perform clean flash before ROM installation.

Clean flashing would be a good option for tbose who have time. But the Oreo update was designed to be a seamless upgrade from OOS 4.x, especially for normal users who haven't even heard of the xda forums.

I don't think the same issues manifested for everyone, but considering the general response in Oneplus's forum, I think the OOS 5.0 problem has some issues.

Just to add, I can confirm better performance and battery life when I downgraded to 4.5.1.

Where exactly is it stated that Oreo is designed like this?
