Downgrade from Oreo stock(8.1) - Moto G4 Plus Questions & Answers

Hi. Just I upgrade from 7.0 to 8.1. using LRSA (Lenovo Rescue Smart Assistant). Previusly i made a backup.
8.1 it´s ok. Then factory reset throught Settings > ... Everything was perfect.
Until I connected the LRSA to try to recover the backup.
The LRSA awaits authorization from the mobile, but the mobile never requests it. (computer's RSA key fingerprint in Android mobile)
I read that i have to go back to some previous version, but nothing worked. The bootloader was not modified.

I I believe all you need is to revoke USB debugging authorizations in settings/dev options

"Secure startup" is missing!

I do not have "Secure startup" option in my S7e settings
This is so strange I rooted my phone a lot before
Is it because of flashing drm disabler in TWRP ?
Any Idea ?

Your device is not encrypted due to what you did, thus secure start up cannot work, there is nothing to secure without encryption lol

So, if I turn on the "secure startup" option, will my lockscreen password be my data partition encryption password? If I turn off this option, my data partition is still encrypted, but with a password (or key file) I don't know? Where does this password (or key file) store?
What if I want to update Samsung apps? I doesnt let me only if I enable secure startup.... but since it's missing I cant install the updates... (on SuperMan rom).
If I'm correct, that is the trick intended for android n stock rom with august patch. That is very spesific situation. I think you're out of luck, mate

A way to unlock hardbricked Meizu Pro 5 ?

Hi,
I've hard bricked my Pro 5. No recovery access, no boot to rom, locked bootloader. After many search i see this : https://forum.xda-developers.com/meizu-pro-5/how-to/meizu-customer-service-flash-tools-save-t3447678, but this is bull-****.
I test many manipulations to get something on my phone other than "Bootloader, Locked".
So i dicovered this : Press and holp Vol + and Vol - and press one time power button. We get this :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
After research about this, we get this :

Hey there. Got the same problem. Tried everything. Nothing happens. Have you got your problem solved yet?
The same problem

Only way to solve this is taking the phone to technical service. Done it myself. Be careful tought, they will try to make you change the entire mother board (280€), but if you insist they will "find a way" to install the correct software in your phone and leave it as if it was new
it is possible to recovery via dongle ... but sn and imei can be lost

Axon 7 Nougat Root

Hello guys.
What is the status about the root / bootloader unlock for Axon 7 running nougat?
these are the specs of my phone right now, and to be honest, after many years of being an iPhone owner I feel kinda lost regarding the root techniques.

NP just read Controllerboy's guide if you have an A2017G.
But before that, be warned about 2 things:
Your data will be wiped after you unlock the bootloader, and if you unlock it you'll probably be wiping and trying ZIPs every once in a while, so get used to backing up stuff and using Google for contacts etc.
That guide was for Marshmallow I think. You can download version B10 or B11 from ZTE's website, then unpack it until you get an update.zip (it should come as a zip with a bunch of numbers, and inside it there's a zip matrioska'd inside). Put it on the root of your internal storage (root means outside of any folder) and go to Settings the Updates. It should find the zip and install it. After that go to Developer options (to enable it go to About phone and tap Build number a buncha times, then it should appear above About phone) and enable Enable OEM Unlock. Now you have Marshmallow and can use the guide.
Another way is doing all the procedure up there but using axon7toolkit instead of that guide. Never used it for this procedure but it should work just fine and do the same. You can get more experience from using the guide though, and that experience may come in handy if you ever tinker too much

Device owner already set before purchasing?

I did a factory reset and wiped the cache, several times in a row last night, because I got sick of a few things and wanted to run a test.
I wanted to install IceBox Apps Freezer. You don't need root, so long as you set it to be 'Device Owner' using ADB shell:
Code:
adb shell dpm set-device-owner com.catchingnow.icebox/.receiver.DPMReceiver
The app says to remove all accounts associated with the device in order for that to work. On our tablets (all models) this isn't possible. So I had to find out a way that would clear all 'device owners.' Google itself is very specific about how this is to be done: Factory reset.
Caution: If provisioning has already started, affected devices must be factory reset first.

Since I did that, and didn't register the tablet with Amazon, Managed Provisioning shouldn't apply. However, I followed all the steps, made sure WiFi was and still is off and went into ADB and this is what I got in return:

Trying to set device owner but device is already provisioned

Um what? Is that even legal?
have you seen anyone having success with Amazon devices?
it's possible they didn't include this feature

As far as I can tell, through all possible methods to gain Device Owner, Amazon has provisioned the devices, en mass, before they are even purchased. Likely done with NFC which is included on the Fires, but is another piece of software Amazon blocks us from accessing and or using. Even a factory reset and attempt to add device owner on language selection screen failed.
IMHO this really should be illegal. What the hell did we actually buy then if we don't own these?
