See post #3 of this thread. Made it couple of months ago ago just for you.

Be aware after downgrading, T-Mobile will probably try to foist the Pie Upgrade back on you. You may have to disable or remove some update files to stay on Oreo.

Downgrade Moto Z Android 7.0 To 6.0

Hi, got this phone for 1 month now used MM for 2 weeks then updated to Nougat but I didnt like it. Now I want to downgrade to MM is it possible with RSD Lite? If yes how? If no will factory reset solve battery drain, awfull notifications, over heating problems?
How did you upgrade? If you updated the bootloader to the N version, I'm not sure if you can revert back to MM.
OTAs are the Evil. :silly:
Updated via OTA. I could downgrade Samsung S4 isnt it possible with Moto Z? I did hard reset, downloaded my apps then closed my phone and charged it. I don't know what happened while phone was booting but it wasn't %100 battery charge btw. This battery life is killing me..
I'm sure you are not able to get back to Marshmallow because the OTA installs a new bootloader that is incompatible with the original Marshmallow

So I have to wait for fix eh
Which version did you apply?
If you updated to Nougat via OTA, there is currently no safe and simple way to downgrade back to Marshmallow as the OTA also updates the bootloader, meaning that Nougat is the oldest OS that is supported on that bootloader.
That's why I unlocked the bootloader on mine and used the technique outlined in the following thread. Not only do you get a perfectly working Nougat OS but also allows you to keep the old bootloader should you decide to downgrade to Marshmallow.

Android Pay detects not only root but also unlocked bootloader.
So in other words, no android pay guys

Ah, I was hoping you had the first release of N. But it looks like you have the current one.
If someone reveals easy and safe way to downgrade please tag me I don't have much time to check forums
Nougat upgrade OTA leaves you in a tough position
My new Moto Z took an update from stock MM to Nougat 3 days after I got it. Stupid me, I should not have accepted the OTA update. But I did. And you cannot go back to MM because the update contains a new bootloader that makes it a one way trip.
Search my other posts in the last few days to see that you are not totally prevented from unlocking and rooting. But unlocking the bootloader leaves a trail forever because a solid state fuse gets tripped forever.

I did not downgrade from 7.0.
I unlocked the bootloader and rooted the phone with twrp 3.xx and then used phh's Superuser.
But I must admit that I have not loaded a third party ROM yet. I want to load stock 7.1.1 when Motorola releases it in February or March.
Question would it be possible to use RDS light or the program at the beginning of this form to unlock set bootloader and then proceed to route

The recommended update for Moto Z

What would be the best (most stable) update for a fresh, purely stock (reteu 6.0.1, no OTA update, bootloader not yet unlocked) Moto Z?
Update through OTA and then root? Would it prevent me from ever going back to Marshmallow?
Leave it without OTA update, root and then flash new ROM? Any recommendation for stability, root and moto-mods support?

If you take the 7.x update then you can not go back to 6.x because it installs a new bootloader. That said, others here may have their own advice. Personally I have had no problems at all with my retus version.

Are you still on 6.x or 7.x ?
If 7.x - did you update through OTA?
Are there any reasons at all to stay on Marshmallow then?

I am on stock 7.1.1
As there is still no OTA 7.1.1 for my Moto Z (which is strange, it seems that reteu got it already), I will probably have to take a more 'manual' way...
I will need unlocked bootloader to root anyway

Pull out the sim card, reboot your device and push the sim card back. Wait a while, then check in settings, about phone, softwareupdate if the 7.1.1 OTA is there.
If you're still on stock marshmallow you should receive several OTAs, one after the other.

Check, if your simcard is recognized by your device under settings, about phone, status of sim....if there is no provider or imei number, try another sim. I recall someone said, the OTA checks for the sim imei. If that doesn't help, try a factory reset and start from 0.

You can try this to get OTAs

Stock 7.1.1 - no problems so far, now I will have to root it.

Downgrade from Pie to Oreo

Hi guys,
Pie is laggy and buggy on my phone. Like on battery saver mode vibration continue to work, and when multitasking it's embarrassingly slow! ... The overall experience is bad. A factory reset didn't solve anything.
I want to downgrade to Oreo 22j. Can someone please guide me on how to do it?
My phone is a stock H930 and I used LGUP to update.
Thank you

Do you mean before the update? No I didn't. But I did after the update, which unfortunately resolved absolutely nothing.

My H930 was also laggy after the V30b OTA flashed with LG UP, even after the factory reset. Then I downgraded to 22j and flashed the V30b KDZ which became available in this time. Whole another world. Smooth as butter.

Hi Edvin73,
Sorry I didn't quite understand.
Did you receive an OTA update on your phone and it was laggy? Which method exactly worked well for you?
I flashed the KDZ available here on XDA with LGUP, and it was laggy for me.

No, I didn't receive the OTA. I flashed the leaked V30b OTA I got here on XDA. Because the experience on Pie was awful (choppy, very bad battery life) even after a factory reset, I reflashed 22j KDZ with LG UP and decided to wait for a official Pie roll out. Few days later, I found out that the official Pie upgrade is available through LG bridge. That did it. My phone is at least as smooth as on Oreo and the battery life is quite amazing but it obviously depends from personal usage. The only thing that seems different is the RAM management. Now uses more RAM with the same settings and installed apps. Regards.
PS: Completely stock, no root, no unlocked bootloader, no anything rather than complete stock.
Thank you for your answer.
Yes I also noticed that Pie uses more RAM than Oreo and the RAM management was bad and random. Maybe 4Go don't cut it anymore? I don't know.
Glad to hear that it's working perfectly for you. Unfortunately I can't update through LG Bridge, I get the "Cannot check the software version" error
It is the same for me, my battery life since I've updated my phone by OTA is awful, is it possible to downgrade without rooting my phone which I've never did?

HOW TO DOWNGRADE BACK TO OREO

While it talks about how to downgrade for bootloader unlock, it's still just downgrading from Pie to Oreo. Same method, no matter the reason.
Downgrading to Oreo KDZ has nothing to do with root. It's just most people who downgrade are doing that so they can then unlock bootloader and root (on early Oreo).
But you can downgrade to most recent Oreo, whatever you wish.
Use the method in post #2, ignore the reason most people use it.

Cheers I'm gona use this :good:
No issues on my device during the first week. Only stock Gallery app is slower and more laggy than before. It's like cache is not working there so every time I open some folder in Gallery it starts loading pictures from beginning which is causing lags.
Some other issues are there with Nova launcher and multitasksing, but this is due to this launcher. On stock everything is fine.

You need Dev Patched LGUP compatible with Pie.
You need to update to newest Dev Patched LGUP found in any of the Pie KDZ threads I maintain. Also found in Frankenstein thread.
Uninstall any prior version. Read Installation instructions carefully!

back to stock PIE UK

Hi guys,
I'm want to go to stock LG PIE Firmware.
I have the LG H930 and am from the UK.
Can anyone help me with how to get back to stock and which PIE firmware I should use for my phone?
There seems to be a wide range of stock pie firmware and want to ensure I get the correct one.
Also wanting to unroot and lock the bootloader
Thanks,
Ross

If you have H930 and you live in UK, the answer is simply the EU H930 Pie KDZ.

I run rooted stock firmware with mods to customize and control my phone. I would never un-root and lock bootloader unless I was selling the phone.

Glad to be of help. I was merely curious about the "wide range of stock pie firmware" comment.
I only post full image KDZ or TWRP-flashable zips based on full image KDZ, and I post those in the ROMs section. Full image KDZ is stock, official LG firmware. (I maintain Nougat, Oreo, Pie KDZ threads for several V30 variants, but they are all clearly labelled for which variant and which OS.)
Yes, someone has posted beta Pie partial image "update" files -- which by definition are not yet official release and possibly buggy.
Stick with KDZ and you'll be OK.
