I wouldn’t suggest it. I haven’t kept up with antirollback. But it’s doubtful

I need the complete firmware, not the update.zip, i try to downgrade from mm to lollipop and now my phone is bricked, i need the complete firmware for extract the system.img (and other stuff) and flash it via fastboot
So far there is no complete mm firmware.
How did you try to downgrade? By fastboot?

you cannot downgrade, as yet there is nothing available to the public to correct it.you will need to RMA your phone, send it back for repair
the MM upgrade changes bits of the eMMC, these changes are not compatible with LP and cannot (yet) be undone. (unless someone knows how to flash nv/ modem / dt from fastboot)

I downgraded multiple times with no problem
I think that the J500H is the only variant with a locked bootloader

Want to rollback my phone to MM but how?

Guys i am not so experienced in this. I am using P9 Lite and the build number of my phone is L31C464B335.
Can anyone please explain me what i have to do to rollback my phone to MM?
I have seen this threat,
https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-roll-noguat-to-mm-l31-21-c185-t3539885
But it's for L31C185. I guess i shouldn't flash them right? Don't want to brick my phone, so any help would be greatly appreciated.

No, it's an offical version but i have this problem,

I believe it's a bug on 7.0 and after returning to MM it will fix this problem.

Have you ran into any problems? Is the change from Android Nougat to Oreo a significant change? Better battery life?

Flash ZV8 on ZVF!!!?

Question to the devs.
I was wondering if there was any way to flash the ZV8 firmware. I know that this ZVF has higher Anti Roll Back version. ARB is implemented on the bootloader of the firmware ZVF. So if I only flash (I know this is silly but want to know) the ZV8 firmware's system.img and boot through QIFL tool will the phone get bricked??

If there’s antiroll back no. Not possible. If attempted and any of the flash goes through instant brick
