Yes just flash latest 7.1 bullhead image and then relock bootloader and you will have your device like stock but why would you downgrade?!

My device is slower than 7.1.2 and also I don't like the layout.
Is there any guide how to do that?
Thanks

Sorry to answer hours after but I didn't got any notifications...
So, download,
platform tools : https://developer.android.com/studio/releases/platform-tools
Latest 7.1.2 build : https://dl.google.com/dl/android/aosp/bullhead-n2g48c-factory-45d442a2.zip
Then exctract the content of the 7.1.2 build in the platform tools folder then connect you smartphone to your PC in bootloader mode (vol down + power button).
Finally in the platform tools folder you will find a file named flashall.bat, simply execute it and you are done, your device will be on stock 7.1.2
PS: This guide was done assuming you know how to lock and unlock your bootloader if not...tell me ? (kidding happy to help ? ).

Unfortunately, I don't know how to unlock and lock the bootloader. I 've never done this before and always had my device stock. Any advice would be helpful!

NOTE : unlocking bootloader will erase all your data!!!
NOTE 2 : If you lock your bootloader without the factory image flashed you will brick your device so no more usable!!!!! So personnaly I don't recommand you to do that because you don't need that to return on Android 7 it's just a "security" for your data.
NOTE 3 : read this guide too because it's more complete and what you are going to do is a bit risky(I speak for locking bootloader) , really! Don't want a message saying "you forgot this line, my device is lost ? ...".
So let's start fun things ?
Go in developer options and enable oem unlock and USB debugging.
Then reboot in bootloader mode and connect your device to your computer.
After that open the prompt command from the extracted platform tools folder by right clicking in this folder with the maj key down.
In this command windows write the following line:
fastboot oem unlock
Or .\fastboot oem unlock if your are on windows 10 (windows is blue instead of black).
When the bootloader is unlocked you can flash a custom recovery then instal a ROM/kernel or flash the factory image.
When you have flashed the factory image (stock ROM...) you can lock the bootloader with this line(same method)
fastboot oem lock (add .\ for windows 10).
Tell me if you need further help ? .

I have to lock the bootloader if I downgrade because bank apps don't work if the device is not stock as far as I know..
other than that I don't mind to be unlocked and playing with custom roms..

That's actually not true, at least I think as I don't use bank apps that don't accept that my bank app is accepting root too ?
But seriously, from where did you catch the info?

I have read comments from developers to advice users whose apps are not functional that the devices should not be rooted and generally should be stock.
Anyways..I will think it again if I continue to the procedure..
PS: I hate the layout of oreo..these white (like LG) squared app icons are simply terrible!

Android layout can be changed easily and having latest Android security offer security and latest features and performances patchs, anyway it's your decision.

Just keep in mind that unlocking the bootloader and flashing the original rom will NOT result in a rooted phone. If you do the this and relock the bootloader, then your phone will be in a totally stock NON ROOTED state. So any concerns that you have regarding root don't apply here.

I am still on 7.1.2 too because of the performance/lag issues in 8.1
... I never upgraded... Is it still really that bad in 8.1 ? Or better with latest patches?

Hi,
my device got bootlooped. Warranty expired 20 days ago and the cost was too high to repair.
So, I followed an online tutorial, flashed my phone and came back to life.
The issue is that the bootloader is unlocked and I cannot use android pay (it says that the device is somehow altered)
Although banking apps work normally.
Is it ok to relock the bootloader?
(what if the device get bootloop again? / is it possible to brick my device? / could I use another way to bypass and activate android pay?)
Thanks

Firstly let me tell you that I am assuming that you have flashed an official stock rom, if you didn't then just ignore what I am saying!
I never heard of anyone bricking the device just by locking the bootlader. The worst thing that can happen is to get a bootloop indeed, but if you just unlock the bootloader again then it should be fixed. Bricking the device just by locking the bootloader sounds totally impossible to me at least. I don't know if there is another way to bypass this and activate android pay but even if there is personally I will not have trusted it.

Unlock bootloader - bootloader mode reboots phone

Hello, I am a proud new owner of the ZTE blade v8 pro, I have been trying to unlock the bootloader to see if I could work on getting root. I enabled OEM unlocking in the debugging and also ADB. The issue I am having is that every time I either use ADB reboot-bootloader or use the traditional hardware keys to get to the bootloader the device just reboots back to normal. I have even tried recovery mode which has an option for bootloader, but when I select bootloader in recovery (which is working) it still reboots normally. I am new to the forum's but I created this one to see if there is anyone else with this issue that has found a workaround. Thank you in advance!
Most likely they locked access to bootloader and adb commands. Just like they did to the ZTE ZMAX pro. Best advice is return the phone and get something else

Thank you for the reply, the only thing that makes me wonder if that is the same is the fact that in the developer options it has a toggle for OEM bootloader unlocking. I have never owned a ZTE device so I am not super experienced with their manufacturer and their ideas on what a good smartphone is but why would they put that option in there if they locked the bootloader and ADB commands? (ADB works in all modes I tested btw). Just trying to see if maybe it is my device or everyone that owns this product. (Example being a corrupt boot image that will start the phone but not fastboot) and once again, thank you for your reply.
:crying:Hello I have the same phone Blade V8 Pro and I hope I don't have to return my phone last night horizontal lines started showing up on the screen I never dropped the phone they show up when in recovery mode also so I know that doesn't look good because recovery is outside the operating system it comes and goes back to normal so is my get worse later on :crying::crying::crying:

I just bought this device a week ago and I was surprised to find "Unlock Bootloader" in Dev Options. I tried the same thing as you (booting into bootloader and recovery) but it didn't work for me either. Did you by any chance managed to figure out how to root the device?

MiFavor is a tuff bootloader that this company uses. I can find no valid method to write files (locked bootloader) via ADB or FTM. I know its a necro here, but I want to warn anyone thinking they might find a method or one will be discovered... it wont.

ZTE V8 SE root!?
emilioangeles95 said:
This guide is technically for all ZTE phones. ZTE phones are quite friendly with developers (but still can’t hit the level of Google and HTC).
How to root
Restart your phone to bootloader (“volume down” + “battery”)
Open up your adb tool and rename TWRP as “recovery”. Drag it into the ADB toolkit and input the following command: “fastboot flash recovery recovery.img”. When finished, type “fastboot reboot” then reboot into system
Transfer SuperSU into phone’s internal memory, find the suitable SuperSU version ( SuperSU V2.64 and SuperSU V2.79)
Switch off your phone. Then press “volume up + start” to enter recovery mode
Install SuperSU by sliding it right in
Reboot, and you are all set XD

ZTE Z978 Marshmallow Kernel(3.18.24)

If it isn't the actual kernel I'm sorry as again I'm not an expert, I just would like to be able to root this phone as the hardware is very good for a cheep ass like me. lol
You'll have choose the "smart phone" category and z978 from the selection menu (not too far down), which has most any ZTE device on there also.
Website: opensource.ztedevice.com
I know that you can't load the kernel if you not able to get past the bootloader, but there aren't any posts in the "kernel" section and maybe there may be a clue in the kernel code on how to unlock and root this phone?, but that's above my current skill level and need the pros like y'all to help if you can.
Hope it helps.

Also, if you have twrp installed, you can flash the OTA zip that corresponds to your current OS version :good:
I do have twrp installed the problem is that I don’t have the zip on the phone to install the ota file.
Try with deceus Script (Just search for it) and select repair bootloop. It will download the factory Image and flash it on a and b partition then your phone will boot again. But your data will be lost :/
Ok., I will let you guys know thank you
Also, I forgot to mention that it looks like that I don’t have a OS installed ( twrp is telling me that every time i try to get out to the get out of the twrp menu. At this point i haven’t don’t anything mention in this post because I’m resetting my computer nd I’m installing right now the android sdk software.
You don't have to install the full Android SDK software for the job you're trying to do. You can download the latest Fastboot commands and ADB through Google, or even XDA(somewhere).
I've installed adb to my Windows commands, so once in recovery, when I need a file, I just "adb push file.zip /sdcard/".
No worries though. You'll be back up and running. ?
Edit: Also, if you still have data on your phone, you can check using the file explorer on TWRP. If you do, you can adb pull anything you want to keep.
@rectangularspace Link to the standalone platform tools HERE. This is all you need.

Why did you decide to install Oreo?? There will be no further security or functionality updates for 8.1. The next monthly update to Pie should be the first Monday of next month (October 1st) if you don't get a OTA nag before then.
I have the update available to install on my settings. But what I'm looking for is to start over on rooting my pixel 2 xl. But after last experience I'm a little conservative when it comes to mess with the phone. I'm reading right now the post where it says to do the critical unlock for the phone but I don't know witch bootloader version I have. Can you guys help me out
I have tmz10n version on my bootloader. It means that I need to do the critical unlock? By the way I did already unlock my bootloader and i Haven lock it again. And I think at some point when I was having trouble with my phone to put it back to run I did also the critical unlock process.

You only need to do the unlock process one time, BUT there are two separate unlock commands which include unlock_critical. If in doubt you can use fastboot device-info or getvar to check the current status. Make sure you are using the latest version of the platform tools I linked to above. One word of caution... don't EVER re-lock your bootloader or you WILL run into problems. Even if you are returning the phone to Google for RMA you do not need to re-lock it.
My bad, after unlock my bootloader I haven't look back again. So it is unlock right now. Thank you for advised. For what I read the only way to unlock it it will be by running the command fastboot right? If I upgrade to pie using the upgrade available in my settings right now, it will not lock the bootloader right?

Yes, once you have successfully unlocked the phone in fastboot using the two separate commands, you will never have to do it again, AND flashing anything will not re-lock the bootloader. Please read over Nathan's GUIDE HERE to confirm you have done this correctly (and completely). Once this is done you can flash OTA's , full Google images, custom roms, etc. Lastly, if you are properly unlocked you cannot brick your phone. No matter how bad it gets, you will always have a path to restore the phone to it's original state. Don't hesitate to take the OTA being offered on your phone. It will take you to 9.0 without losing data or locking anything. :good:

Yes did anything ever come of this? Also when you unlock it, does it you to root it?
So is there a way to get the OEM option to appear in the dev options or a way to install a bootloader without OEM?
I'm having the same exact problem with my phone. Same model and everything and I also do not have the unlocking option In my dev options. I've tried every exploit known to me and have no luck. I tried flashing TWRP theough Odin without the OEM unlocking and I get a fail because of a secure check fail which I'm not sure is related to the bootloader not being unlocked or something else. I'd love to get an answer to this so I can get lineageos on here

There is no OEM unlock option in the dev options for this phone.
The most I could do is to get in to go into download mode, no bootloader came up.
I Used ADB Command: adb reboot bootloader
Another PC app I seen on xda forums is called "ADBAppControl".
There is an option reboot your phone with adb built in to do it too.

My J2 is new and No at this Point, One Reply in here said after 160 days of owning it the option opens up, so I will have wait for the 160 days are up to check again.
Update, it been Over 160 Days and still do not see anything in the dev options. I bought the phone 4-12-2020. So i guess it lockout code that releases the option i suppose. or it just not available with this phone.
Was thinking of flashing my old stock 4.1 on it. cause 4.1 i had no trouble rooting it.
Yes,I'm new to the forum. I also have the same model phone unlocked from the carrier(Metro PCS). I've tried several ways to root this device but I don't have access to a PC I also get the security error code to pop up when I tried to install custom OS. I can't seem to get the recovery backup or to actually Flash the proper image to the bootloader I've also tried kingroot, kingoroot, l root, and some other one click root options. My understanding of using team Win Recovery Project without PC is limited I'm also trying to use magisk with it.In A novice in understanding...Does anyone have any advice..
Better find a friend with a computer to help you . Apps are crappier than Microsoft.

Bricked or not bricked, that is the question

Weird screen behavior, it seem to me that it isn't a hardware fault, cause when plugging in a charger the phone is able to show the MI logo, but not the charging icon
The phone is able to boot and i can hear the phone locking and unlocking, can see that the screen is on because of the backlight, but there is no image, SO FRUSTRATING!!
If you have any idea of what's going on and can give me a tip, i would thank you so much, the phone has been on this state for a long time
Don't know how to upload videos, if you think that can help diagnose it i can upload it and share a link or something

What did you do before?
Did you flash something?
Is it device unlocked?
This happen also in fastboot/recovery mode?

I hadnt updated my Rom, Pixel experience, in a while, so i took the opportunity and flashed an (at the time) beta Pixel Experience Android 10, i reverted and everything was fine for about one day i think, then some artifacting wich would come and go until the display gived up completly (about an hour between the two)
Yes, it is unlocked, and when in fastboot/recovery the screen is lighted up but not showing anything
My guess is that i have a low level firmware issue, as i had problem with those before (was running a custom ROM from day 1, so i had to manually update firware to use newer versions of PE (still pie version) and almost bricked my device

Then try the next:
- Flash a different vendor.
- Flash a different kernel.
- Revert to stock ROM, no need to lock or nothing, just flash first the recovery ROM but if it doesn't result then flash the fastboot ROM through EDL, so that you know you can boot to EDL mode without need to open the back cover, this will restore all the original images.

You can flash some images invoking the right partition, I mean, you can flash vendor image onto the vendor partition using
Code:
fastboot flash vendor vendor.img
, and in case you need to flash all the ROM you should use MiFlash tool

I actually want to check that, i took the phone to a tecnitician and he may have locked the bootloader
I think the next step would be flashing the vendor, firmwares and stock rom again, right?

if your bootloader is locked, you can't flash through fastboot mode either vendor or stock ROM, you should need to use EDL method or you can re-unlock bootloader and this way will work. Anyway i don't understand what actually your issue is.

The issue is the display not working, and it's gotta be a firmware issue as it's on my desk right now showing a bunny, also i am not used to fastboot flash anything, i just was used to recoveries and what not
Just runned some code and it's locked, this is getting better and better oh boy
How am i gonna unlock this if i can't even unlock the phone? last time with screen working it was already a nightmare, having to wait for miui account, do i have any method of doing this without using EDL?

Well, this make sense although it's not clear if you did unlock it previously and after that at some time you did lock it again.
If you didn't unlock it previously you would need to bind your Mi account to the device and enable USB debugging and OEM unlock options but if you didn't before without a screen working you have a more difficult way, confirm me if that is the case.
Anyway I got happily surprised when I bought this device some months ago at the first attempt I could unlock it without have to wait time, try it and see what happen.

It was unloked and i locked again, don't know if this helps my case or if i am royally screwed up
And yeah, Xioami does make difficult to do the process of unlocking but only to recently released devices, aparently to stop re-sellers to buy the cheaper chinese rom and put the global version on them, i think that when a device doenst get made anymore makes sense that they would make it more easy (i bought the device 2 weeks after launch)

Ok, of course this makes a huge difference, if you did unlock it previously then you couldn't receive any wait time, I wonder why you didn't try it if you didn 't. Check if MiUnlock tool unlock your device instantly.

Hmm, OK, now you have your way sorted out, you can try with a custom ROM (all of them contain a vendor) or in case a custom ROM doesn't solve it you have to try a stock ROM through Mi Flash tool.

Ok, but how am i gonna flash a rom with fastboot? Is that a thing?
Also, i don't think the vendor is gonna be my only problem, but also the firmware, is there a way to flash firmware without the recovery and trough fastboot?

You can't be sure of that, sometimes the vendor correct the issue, sometimes the firmware.
Firmware it is in the stock ROM that can be flashed either through fastboot or EDL mode (be careful to not relock bootloader or you couldn't enable this time OEM unlock option). Now that you have the way more clear just do a search "how to flash stock ROM on Xiaomi devices either through fastboot or EDL mode", just keep in mind that you don't need to open the back cover of the device, usually from a device off (only on unlocked ones) you could send it to EDL by pressing both volume buttons at same time that it is connected to PC, I gave you the main tips, for the rest you will find a lot of tutorials.

Question I'm very overwhelmed please help

The last time I rooted a phone was 3 years ago, in general whenever I try to root a phone I feel like the entire process has changed and im completely out of the loop.
All i want to do is make it so i can install f.lux and youtube vanced, how do I do this?
I know that I need to install magisk but apparently I also need to enable the bootloader whatever that means?
Sideload, flashing, caprip, boot-image, fastboot, TWRP: these words mean nothing to me, they serve to confuse and demean me.
Is there any resource for figuring out how to go from a new out-of-the-box moto g30 to one which lets me install youtube vanced? Usually I'd look up a tutorial but the only one I found was in spanish and I don't speak spanish.
Thanks for any help you can give.
First things first.
Android has Night Light built in and Youtube Vanced doesn't need root.
But, if you're still serious about rooting and installing magisk to make use of all of the really useful modules, you'll need:
An Unlocked Bootloader: Motorola's Own Guide
Keep in mind that unlocking the bootloader will wipe your phone and void its warranty, so be absolutely sure you want to do it and back up your files.
Then you'll need to manually patch a boot.img from your stock ROM (can be found here.) and flash it using ADB (Android Debug Bridge) using your PC.
I rooted mine within 3 days of owning it and have been enjoying it with no problems whatsoever ever since.
I used this guide as reference. If you have any questions you can always just message me here or on Telegram (@Kuntitled).

Bootloader is small program which runs before Android operating system running. Bootloader is first program to run so It is specific for board and processor. -RootJunky

Unlocking the bootloader
You can flash a custom system only if the bootloader allows it. Note, though, that the bootloader is locked by default. You can unlock the bootloader, but doing so deletes user data for privacy reasons. After unlocking, all data on the device is erased, that is, both private app data and shared data accessible over USB (including photos and movies). Before attempting to unlock the bootloader, back up any important files on the device. - https://source.android.com/setup/build/running

The boot.img is the fie that creates the boot partition
/boot​This is the boot partition of your Android device, as the name suggests. It includes the android kernel and the ramdisk. The device will not boot without this partition. Wiping this partition from recovery should only be done if absolutely required and once done, the device must NOT be rebooted before installing a new one, which can be done by installing a ROM that includes a /boot partition.

Fastboot refers to several things
Fastboot is the fastboot protocol to communicate with an Android device.
Fastboot.exe is the part of SDK Platform-Tools used to communicate with an Android device when it's in fastboot mode.

TWRP:

Twrp is a Custom recovery,
The stock recovery has very limited functions,
a custom recovery has more options
/recovery​This is specially designed for backup. The recovery partition can be considered as an alternative boot partition, that lets the device boot into a recovery console for performing advanced recovery and maintenance operations on it. -RootJunky

Hi thanks this really helped me get the grip of things haha.
I managed to unlock the bootloader but I'm a bit confused on what stock ROM you were referring to, the link you sent had a bunch of possibilities, I assume I need a reteu one since that's the name of my phone's software channel but there's a wide variety of them and the guide you sent seems to have their own ROM as well.
Either way thanks for all the help!

You should check the Build Number under "About Phone" in settings, and match it what you find on that link i sent.
