Downgrading from Nougat to Marshmallow - Moto Z Play Questions & Answers

I understand that bootloader and GPT can't be downgraded because it would cause brick. But the rest of the files should be OK. If this is so, can I just remove those files from flashable zip and flash it away?

You can try but you could end up not boot up, which would leave your device unusable until the firmware comes out

So there is no safe way to downgrade in any way?

Only safe way is through TWRP.
Let some else attempt it.
There's too many risks IMO

Regarding TWRP, unlocked bootloader is needed?

To unlock your bootloader you have to ask Lenovo for a key number, once they issue a key number they know that you unlocked your bootloader.
There has been cases where people ask for the unlock key and never unlocked the bootloader, but Lenovo void the warranty just because they asked for the key number.

You'll never truely relock it anyways, there's a permanent flag that will persist.
As soon a s you ask for your individual unlocking key you've voided your warranty.
You can roots to fight the warranty issue if your country permits.
Us Canadians are screwed, oh well ,I have never hard bricked a device to date.

What til the second nougat update comes out.

to perform a downgrade, you should erase the following lines in the flashfile.xml or servicefile.xml:
<step operation="getvar" var="max-sparse-size"/>
<step MD5="XXXXXX" filename="gpt.bin" operation="flash" partition="partition"/>

Have you attempted it?
You're still flashing stuff that could cause major issues and there's no firmware around for nougat.
I will stop warning people.
I've had a few moto devices and I have seen things go bad real quick.
IMO it's best just to leave things the way they are.
Never flash anything unless you have a back up plan, specifically your firmware.

I have already done it. The main thing is not to try to overwrite the BL and the partition table (GPT). It's a risky process, however I have worked with the Zplay and other moto devices and this steps works.

7.1 Nougat

The Moto E4 has been released running Android 7.1 out of the box. Frustrating for probably most of us running 7.0, but this is a good indication that we will get the 7.1 update. Just thought it'd be an interesting tidbit for those who want 7.1.

Lenovo hasn't really been reliable with updates... It took over 6 months to get Nougat on the G4, I wouldn't put it past them to skip straight to 8.0. But this is a good sign... Hopefully I won't have to wipe my phone and go to the unofficial Lineage to get it.

I guess it cannot be flashed on European H815, right?
Asking, because I think the reverse was possible (EUR kdz on Korean variant).
Happy flashing everybody!
Nope, unfortunately.

I have F500S but using F500L firmware(they are all basically same,just different phone operators).LG BRIDGE recognized it as F500L and offered Nougat update.LG UP recognized it as F500S but would not flash F500L kdz or F500S kdz downloaded from top of page.Had to revert back to BRIDGE,which can be hit and miss if your internet speed is deemed to slow for them,and updated ok.Have not tested it out yet to see any improvements
Any way to remove Korean bloatware?Or root?

1-) Download Win Hex
2-) Open F500K.kdz File (with win hex)
3-) make CTRL+F
Replace with F500K H815
(F500K=H815)
4-) Ctrl+S
5-) upload with Lg Up =)

[MODULE][MAGISK] Long camera start fix for Mi A1

This is a very simple module that fixes long camera start on Mi A1 without making your system insecure by forcing permissive SELinux mode or using permissive domains.
Github repo: https://github.com/Flex1911/tissot-camera-delay-fix
It's working. Thanks!

I tried it again. This module turns off multiple modules. For example, Xposed framework and fingerprint wakeup. Unusable for me.

Yay! Your here @flex1911. So good to see you doing work for Mi A1. I was also a user of you LOS 14.1 for Asus Zenfone 5 which is still working. Hope to see more from you. Keep up the good work bro.
Thanks for sharing @flex1911, I took the necessary command and put it into Tasker as a startup task and it works fine as well. Those who have issues using Magisk module can try this approach..
Thank you so much buddy ?
Thanks buddy.
For me Clean flashing stock rom with February update fixed the problem.
Tried
Code:
magiskpolicy --live "permissive camera_prop"
magiskpolicy --live "permissive hal_camera_default"
Both didn't fix any lag.
Also tried
Code:
magiskpolicy --live "allow hal_camera_default surfaceflinger_service service_manager find"
That also didn't fix any lag.
Its ?% working
Works perfect.
Thanks !
It works fine and does not break xposed or the fingerprint wakeup.
