How to lock bootloader after it was unlocked - Lenovo P2 Guides, News, & Discussion

This method was tested on P2a42 4/32 and P2c72 4/64 (both smartphones has 251 firmware installed).
Please, pay attention and read carefully:
You have a risk that P2 will go from EDL (9008) mode to 900E while you make a reconnect of connected to PC phone.
If you haven't successfully returned it by yourself into 9008 state - the only way is repair service. See details on 4Th step below the short instruction.
ADB and EDL (9008) drivers have to be pre-installed on your PC.​
For those, who faced with flashing firmware, gaining root, working with ADB and Fastboot commands, EDL mode on P2 and so on, here is the short instruction:
1. Wipe sp if you have root: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp .
2. Wipe secinfo via Fastboot: fastboot erase secinfo .
3. Wipe userdata via Fastboot: fastboot erase userdata .
4. P2 is connected to PC in EDL (9008) mode, make a reset via launching blank-flash.bat from blankflash folder.
5. Flash 251 firmware as for unlocked device using START script .
6. Choose region ( ####682# ) and then make a reset ( ####7777# ).
7. That's all folks! Now you have locked P2 with a region that you want. So you can set the phone as you always do.
Below there is the same instruction, but detailed and with pictures.
From Unlocked to Locked state on P2.
1. Wipe sp if you have root: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp .
On this step you can use Total Commander with ADB plugin (YouTube will help you, there are tons of videos about it).
I prefer not to use PC, if there is another way.
What I've done:
Android Terminal Emulator installed and launched.
Gave it permission to root access.
In Emulator typed su and pressed Enter.
Sign $ will turned to # , which means that further commands will be under root access.
Type command: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp and press Enter.
If all done right, so you will see: Screenshot 1.

2. Wipe secinfo via Fastboot: fastboot erase secinfo .
Turn off P2.
Boot it into Fastboot mode - press and hold two buttons (Power And Volume -), on P2 screen you will see Fastboot mode: Screenshot 2.

Connect P2 to PC (it is recommended not to use card readers; connect to USB which are situated on motherboard for PC, there is an exception for notebook (laptop)).
Press right mouse button and hold Shift on ADB folder, which is placed in the root of Disc C (С:\), choose "Open command line" - a CMD window will appear on the screen of PC.
In CMD window type fastboot erase secinfo and press Enter.
If all done properly, all drivers set properly, on the screen of your PC you will see: Screenshot 3.

3. Wipe userdata via Fastboot: fastboot erase userdata .
Continue in CMD window. Type fastboot erase userdata and press Enter.
On the screen of your PC you will see: Screenshot 4.
View attachment 4358526
Close CMD window on PC.
4. P2 connected to PC in EDL (9008) mode, make a reset via launching blank-flash.bat from blankflash folder.
blankflash folder must be placed in the root of Disc C (С:\).
On PC you must hold opened window of "Device manager" with opened string "Ports (COM and LPT)".
Your P2 must be connected to PC in EDL (9008) mode.
Use P2 very carefully without further re-connections, because there is a high risk, that P2 can go to 900E mode.
P2 connected to PC, press and hold all three buttons (Power and both Volume).
Hold buttons (phone will be rebooted twice) until you will see "Qualcomm HS-USB QDLoader9008 (COM12)" in opened window of device manager in string "Ports (COM and LPT)".
You might get another number of port (not only 12Th), it doesn't matter.
The main aim is "Qualcomm HS-USB QDLoader9008..." string in device manager.
Please, be very careful, because even little re-press of button or re-connect of cable will send your P2 to 900E mode with constant vibration and blue LED.
Try to restore phone to EDL (9008) mode by pressing and holding three buttons.
If you have no luck (from 900E to EDL) - congrats, you've got a brick.
From this point you should ask for help in repair service.
Going further, if all is going right and P2 connected to PC in EDL (9008) mode.
In device manager window on PC you will see this: Screenshot 5.
View attachment 4358527
From blankflash folder launch (double click of left mouse button) blank-flash.bat: Screenshot 6.
View attachment 4358528
You will see a CMD window which shows you a reset process of your P2.
If all done properly (without any "ERROR False"), you will see: Screenshot 7.
View attachment 4358529
In the end of reset your P2 will automatically boots from EDL (9008) mode to Fastboot mode: Screenshot 8.
View attachment 4358530
I suppose that there is no need to speak about 5Th and 6Th steps, because it is a basic knowledge, that you should know, when you are going to lock bootloader on P2.
Important notice.
You have to use original or other cable that has been already successfully used in Fastboot mode with your Р2.
The simple way to check cable is to type fastboot oem config in CMD and look what info it will give to you.
For those, who have already locked bootloader, it is strictly recommended not to flash stock ROM via flashall.bat.
For flashing stock you should use method for unlocked device, so you need to use START script.
All will go right if you will flash via flashall.bat after bootloader was locked, without any errors, Р2 will be booted as usual - Wi-Fi, SIM-cards (with names of operators), IMEI's and Serial number - all will be OK ...
But!
Calling, SMS and Mobile data will not work, you will see crosses on antenna icons in Status bar (in the string of modem firmware in "About" you will see "X" instead of "R" (Screenshot 9, 10) as it was, modems region will be defective).

You can switch on/of Mobile data from Notification drawer, but there will be no connection, only Wi-Fi will work.
I am searching for solution of this problem.
As soon as it will be ready, it will be posted here. See post #2.

All thanks addresses to https://forum.xda-developers.com/member.php?u=279908.
I've just translated it from Russian to English from 4PDA site
Good luck and have a nice day!
Remember ...backup rules.

Solution.
Your phone must be unlocked and you must already have TWRP-backups of modem (NON-HLOS) and EFS from Р2.
1. Unlock bootloader.
2. Install TWRP.
3. Restore modem (NON-HLOS) and EFS in TWRP - you will get working modem, but there might be no sound in telephony.
4. You should install modem image via TWRP for Android 6 or 7 to get back to a working telephony (for additional instructions see post #3).
Later, if there will be a method which will work without TWRP-backups and possibly without unlock of bootloader, it will be posted here.

How to restore a modem.
Important notice - you need to use modem with the same OS version which is installed on your phone.
Look here:
Firmware 062 - this is Android 6.
Firmware 233 and higher - this is Android 7.
Flash this:
For Android 6 - Modem_P2_062_ROW.zip
For Android 7 - Modem_P2_244_ROW.zip
Flash modem via TWRP:
1. Download zip for OS that you need (do not unzip it, rename or choose extension).
2. Copy to the phone memory (or to external micro-SD card).
3. Boot to TWRP and act as it is shown on the screenshots ...

It is a difficult question.
I suppose, that official repair service can detect it.
Remember how you unlocked P2 at first time: you asked for unlock with internet connection and Lenovo ID, there is a possibility, that some data about it stored and can be used for different purposes.

I agree... But there are some reports on this forum suggesting otherwise.
One common report is the replacement of motherboard for bricked devices, that too for unlocked devices.

Yes, as long as you are on stock rom.

I lost my signal forever when I did a nandroid backup from another P2. I've tried it all, but nothing seems to work when it comes to restoring it.
I'm a bit confused by the first posts. OP talks about locking the bootloader and post #2 and #3 say you have to be unlocked to restore the modem? I'd have thought you wanted to lock it in order to flash the modem.

[HOW-TO] Unlock and Root Moto G via Recovery/SuperSU

Unlocking the Bootloader is Required! This will erase all data and void your warranty!
Since all data will be wiped it's best to do this immediately after getting the phone. At least unlocking the bootloader.
I won't add a disclaimer, because if you trust some guide from some guy on the internet you should know what that means without being told explicitly.
For me the bootimage method posted on Modaco does not work and apparently others seem to have trouble as well (see the poll at Modaco). And since I couldn't find any guide here on XDA I thought I'd write one. XDA helped me a lot when I got my DHD, so maybe now I can help back.
This is based on soyd's guide at swedroid.se which I used to finally get my phone rooted after some unsuccessful attempts.
The guide is for Windows, but could probably be easily adapted to Linux/Mac by using the appropriate drivers/tools. I followed these steps to successfully root my Moto G (16 GB, german retail, Android 4.4.2, OTA 176.44.1).
Here're the neccessary steps:
Install Motorola and ADB Drivers
Unlock Bootloader
Flash Recovery
Flash SuperSU
Enjoy
Install Motorola and ADB Drivers
Do not connect your phone to your PC just yet.
If you already have ADB drivers and Motorola drivers installed, just skip this step.
Download these files:
Motorola Drivers
ADB Tools (thx to androidpit.info)
mfastboot.exe (only download that file from the G-Drive folder - thx to whoever uploaded it)
Run the MotorolaDeviceManager_2.4.5.exe you just downloaded and install it
Extract the two folders from adb-tools_treiber.zip
Open ADB-Treiber folder and run UniversalAdbDriverSetup.msi
Copy mfastboot.exe to ADB-Tools folder
Now this next part might be optional, but some things might not work without it and there's no real harm so:
Enable USB-Debugging
On your phone, open Preferences
Scroll all the way down to About this phone
Scroll all the way down to Build-Number
Tap 7 times on that entry
You'll get a message "You're a developer now"
Go back and open the new item Developer options
Check USB-Debugging
Connect your phone to the PC
Drivers will be installed and the phone will ask you to confirm USB debugging from that computer
Unlock Bootloader
There are probably lots of guides around, but to have it all in one place, here's yet another one:
!YOU WILL LOOSE YOUR WARRANTY AND ALL DATA BY UNLOCKING THE BOOTLOADER!
Switch off your phone
Hold Volume-Down and press and release Power to boot into Fastboot
A text screen should appear
Connect the phone via USB to the PC
Open a command prompt and browse to the ADB-tools folder you just created
Type:
Code:
fastboot oem get_unlock_data
You'll get five lines of characters, all beginning with (bootloader):
Code:
(bootloader) 0A40040192024205#4C4D3556313230
(bootloader) 30373731363031303332323239#BD00
(bootloader) 8A672BA4746C2CE02328A2AC0C39F95
(bootloader) 1A3E5#1F53280002000000000000000
(bootloader) 0000000
Copy all lines into one long string without the (bootloader) part!
You want something like 0A40040192024205#4C4D355631323030373731363031303332323239#BD00 and so on.
Open Motorola Unlocker Site (you need to sign-in)
Copy the string in the box at 6. and press Can my device be unlocked?
A Request my Unlock Key button should appear. Check I Agree to the legal stuff and press that button
Check your mail for the unlock key
In the ADB-tools folder type:
Code:
fastboot oem unlock [I]paste_your_key_here[/I]
The phone should reboot and greet you with a nice warning about you having lost your warranty.
Flash Recovery
Now that the booloader is unlocked you have to flash a custom recovery to be able to flash SuperSU.
Download the CWM image from this post. The file should be named something like recovery-clockwork-6.0.4.7-falcon.img. Copy the file to the ADB-Tools folder you created earlier and rename it to CWM.img
Your phone should still be connected to your PC and have finished rebooting and be in stock ROM.
In the ADB-Tools folder type:
Code:
adb reboot bootloader
The phone should reboot and the bootloader will come up again
To make sure all's working as expected type:
Code:
fastboot devices
You should get a response similar to:
Code:
List of devices attached
TA93005M6V device
To flash the custom recovery, type:
Code:
mfastboot flash recovery CWM.img
On the phone you might get a message about size mismatch, just ignore it. Now you have to enter the newly flashed CWM recovery. Take your phone and:
Press Volume-Down to scroll to the Recovery menu item
Press Volume-Up to select that item (yes, Vol-Up selects)
The phone will boot into recovery
Now is a good time to backup your system.
Press Volume-Down to scroll to Backup and Restore
Press Power to select that item
Press Volume-Down to scroll to Backup to /sdcard
Press Power to select that item
Backup will commence, once it's finished go back to the main menu and select Reboot, then confirm with YES
You phone will reboot into the stock ROM.
Flash SuperSU
Now you can finally flash SuperSU and be done with the whole business.
Download the newest SuperSU and save the file to your phone's SD-Card's root directory. The phone should show up as an MTP device in Windows file explorer.
In ADB-Tools folder type:
Code:
adb reboot recovery
The phone will reboot and once CWM Recovery has come up, use the Vol-Up/Down keys to scroll and Power to select
Select Install zip
Select zip from /sdcard
Select /0
You should find a file like UPDATE-SuperSU-v1.94.zip there.
Select that file, confirm YES and wait for the flashing to finish
Go back to the Main menu and select Reboot, confirm YES
The phone should once again reboot into normal stock ROM operation. To check if all went well, open the app drawer, tap on SuperSU and if no error message comes up... You're done!
I hope there are no mistakes anywhere in this guide and also that it might be helpful to some people...

Great guide, I used it to root my Moto G I got today but I had problems with flashing the Clockworld recovery. It simply would not work, said error. But I tried TWRP and it worked. But I also named it recovery.img and used your command but replaced CVM.img with recovery.img. Got rid of ALL of the bloatware. I was stuck at first because I didn't start the command promt inside of the adb tools folder.
Recovery issue
Guys I had a similar issue while flashing the cwm.
When I flash it in the first boot it works, I can enter in the interface and can create a backup or flash one, but after a reboot it do not enter again. I tried entering via fastboot -> Recovery and received the dead android icon with the "No command" message.
Tried installing via PlayStore and had the same result, even with the TWRP.
Any ideas ?

[Root][Sony Xperia Z2][MM][23.5.A.0.575] unlock bootloader, root and ROM flashing

SONY Xperia phones have unlocked bootloader which adds to the difficulty of rooting on top of MM.
#######All the works posted here are not mine but of various authors to whom I am gratful for helping me achieve root############
Requirements
Locked Bootloader Xperia z2
Stock SONY ROM
no root
Battery above 70(just to be safe)
Good internet connection
Now, we have lots to download because Flashtool dosen't work so, I had to download android sdk entirely.
#1
Obtaining the Bootloader Unlock Code
Note:Unlocking the bootloader on a Sony device may automatically wipe internal storage; a backup of the sdcard is suggested. It will also irreversibly erase the DRM keys stored in the TA partition of some devices, which will result in the loss of certain proprietary features that may have been included. Check your specific device forum on XDA to learn more.
In order to unlock the bootloader on your Xperia Z2 you will need to obtain a code from Sony. The following process will help you acquire this code so that you can flash a custom recovery.
Open the Phone application on the Xperia Z2 and enter *#06# to obtain the device's IMEI, IDID or MEID. Save this for later use.
Optional: if you do not have a phone app, the IMEI, IDID or MEID can be found on the box or on the device in Settings -> About Device -> Status.
Put the device into fastboot mode:
Insert one end of the Micro-USB cable into your PC. Turn off the device and wait at least 5 seconds. Press and hold the Volume Up button and plug the other end of the Micro-USB cable in to your device.
Open a terminal on the PC and enter fastboot getvar version
If you receive the message <waiting for device> fastboot is not configured properly, please see fastboot for more details.
Navigate a browser here
Select your device and click the 'continue' button at the bottom of the page.
Enter your email address, agree to the terms and select 'Submit'
Click the link from your email, enter your IMEI, IDID or MEID and continue
The unlock code should now appear, write this down for the next step.
In the PC's terminal, enter the following command: fastboot oem unlock 0xKEY
KEY corresponds to the unlock code you were given.
The Xperia Z2's bootloader should now be unlocked.
This should factory reset the phone, you may have to wait a while before reboot.

After unlocking the device, rooting is done using Kingroot (easier), you can use either the windows app or android app.
Success rate of rooting however is very less, so you may need to do it more than a few time.
The rooting lasts only 2 restarts(for me), so you have to root again using king root.

windows: https://kingroot.net/

Now, you have custom recovery, you can use this to flash ROMS. Caution to be taken when you flash a ROM you might loose your Kernel and recovery so use ROMs with inbuilt kernels or just flash after installing depending on ROM
For D6502 phone you will need to flash a fix zip after the ROM for getting network.

[ROOT] Coolad Modena 2 / Sky 2 (E502)

Recently, I successfully ported TWRP from Coolpad Note 3 Lite to Modena 2. After testing, everything works fine, on both devices. Since this device has locked bootloader, we need to bypass this by enabling fastmmi mode and factory mode to enable temporary root access and make initial backup and flashing. So, let´s get started.
Remember to read this post carefully. I am not resposible for any damage to your device. If you brick your device while flashing the TWRP you can *almost* always recover it using SP Flash Tool and YGDP Tool
IF YOU ACCIDENTALY BRICK YOUR DEVICE AND YOU WANT TO FLASH IT VIA SPFT, DO NOT FORMAT THE DEVICE IN SPFT!!! If you´ll format partitions in TWRP, that´s fine, but don´t do FORMAT ALL + DOWNLOAD or FIRMWARE UPGRADE! This will brick your device, like mine This tutorial will not (hopefully) brick it, but just in case something goes wrong, now you know what not to do.
Preparing the environment on your computer
Windows
Download ADB and Fastboot from this link
Open it
Install it system-wide
Also, install the drivers
GNU/Linux (Ubuntu / Debian based distros)
Open terminal
Type "sudo apt install adb fastboot libusb-dev" without the quotes (")
Other things, that are required
Since the file size of the recovery exceeds the maximum 8MB of allowed upload size, you can download it from DataFileHost.
Preparing the device
First, you need to remeber that this could render your device unbootable and will void warranty.
Enable developer options
Go to Settings -> About phone
Tap the build number 7 times
Go back
Go to Developer options
Make sure OEM unlocking and USB Debugging is enabled
Enabling factory mode
Open dialer app
Dial *#9527*#
Click on "DM"
You will be prompted to insert RD personnel password. Enter: 54321
Click cancel button
DM button should change colour to RED
Exit the app by clicking home button
Installing and setting up openrp app
Open terminal / command prompt
Type:
Code:
adb start-server
Type:
Code:
adb devices
Now, click on your phone allow debugging and make sure to tick the radiobutton to remember / always trust this computer
Type:
Code:
adb install
Press spacebar after the install word and drag and drop the downloaded openrp.apk file to terminal
Hit enter
After it´s done, type:
Code:
adb shell monkey -p com.yulong.openrp -v 500
Now, the fun part. ROOTING the device
But before that, BACKUP
Now, keep your phone plugged in, and do a normal reboot by pressing and holding the power button and clicking reboot
When it vibrates, press and hold the Volume down key (Vol-)
You will see these lines on the screen:
Code:
=>[Factory mode]
Code:
=>VolumeDown key is pressed
Code:
=>[fastmmi mode]
After that, you´ll see the LED turns green and "Up Down" text on the screen
Now, back to your computer, type in the command prompt
Code:
adb devices
You should see XXXXXXXXXXXXXX device listed (where XXXX... is the serial number)
Type in the command prompt:
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery of=/storage/self/primary/stock_recovery.img
and
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/boot of=/storage/self/primary/stock_bootimg.img
Flashing the TWRP Image
Type in the command prompt:
Code:
adb push (drag and drop the recovery image file here, like you did with the openrp.apk file) /storage/self/primary/
Type:
Code:
adb reboot
Press and hold VolumeDown key (Vol-) to boot to fastmmi mode
Type:
Code:
adb shell dd if=/storage/self/primary/recovery_twrp_e502.img of=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery
Type
Code:
adb reboot
Press and hold the VolumeUp key (Vol+) to boot into recovery. If you see white screen with "Recovery" text in it, congrats. Everything is working. If not, try again.
Flashing the SuperSU package
Download the zip from SuperSU website
Copy the zip over to the device, with TWRP running
In TWRP, click install, click the zip and confirm the installation.
Factory reset is not required, but you should at least wipe the cache

Hi i have a problem here. at the part to drag and drop the openrp file. When i have downloaded the file a drag it and drop it after the install word. The problem is that if I want to drop it there it will do nothing, nothing there shows or anything. Please respond.
I guess you can type the path to the installation file instead of dragging.
Hello,
Very helpful thread, my coolpad Modena 2 (E502) is now rooted.
Don't forget to disable the factory mode once everything is done, or you won't be able to access the storage to usb anymore.
Thanks.
helo, can i get help, when i try to install openrp on abd and fastboot, it printed this message "Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]"
can anyone help me on that step, so i can root my e502

Hello,
If I recall correctly (I don't have the phone anymore, just touched it once to root it at the time), you basically undo the "Enabling factory mode" step.
I think if you dial the number, you'll be back in the menu where you have the option to disable the factory mode.
Factory mode should be disabled when 'DM' is green.
Good luck
very good
Need Custom rom please

Hello, could you resend the twrp recovery file for this phone again?. old links not work!.

LG Aristo 2 ROOT (LM-X210[Build- X210MA10i])

===============================================================================
TUTORIAL REVISED AND WRITTEN BY @parcek
===============================================================================
FURTHER UPDATED FOR ROOTING NOOBS: 10 Steps
Two Methods: Windows and Linux
Originally posted by @brad2192: https://forum.xda-developers.com/android/development/lg-aristo-2-root-t3746425

@brad2192: Updated Tutorial due to people using TWRP (the original tutorial was released before TWRP was released for this device)
1) Backup all apps and data using LG Backup phone apps
2) Enable USB debugging and Unlock OEM. There are two methods in which you will to accomplish this:
First Method: Smartphone GUI
A) On your Lg Aristo 2 Smartphone go into General Tab (If in Tab View), If in list view, scroll down towards System section
"System Settings > About Phone > Software Information > Click on "Build Number" 10 times.
Now go to "System Settings > About Phone > Developer Options > Enable OEM unlock."
and also "System Settings > About Phone > Developer Options > Enable USB debugging."
Second Method: Windows Command Prompt or Linux Terminal:
Windows:
B) Click and drag "adb" file into command prompt and type "reboot bootloader" after it. Press enter.
Click and drag "fastboot" file into command prompt and type "flashing unlock" after it. Press enter.
Linux:
C)Type in your terminal "adb reboot bootloader" and press enter.
Type in your terminal "fastboot flashing unlock."
NOTE: Below has the information which will teach you how to download ADB and FASTBOOT.
3) Download the following:
Updated - TWRP
Updated - Magisk
(Add this file into your phone's SD Card.)
Updated - boot image
Update: Windows:
B)This is how you download ADB and FASTBOOT for Windows: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
4) Open Command Prompt. Then click and drag the adb file (from the latter download link a.k.a platform-tools) into command prompt then press space and type "reboot bootloader" after and then press enter OR power down phone and hold volume down while plugging in USB)
5) Open Command Prompt. Then click and drag the fastboot file (from the latter download link a.k.a platform-tools) into command prompt and then type "flash recovery" after it and then click and drag "newtwrp.img" into command prompt and press enter.)
6) Open Command Prompt. Then click and drag fastboot (from the latter download link a.k.a platform-tools) into command prompt and then type "flash boot" after it and then click and drag "bootimglistedabove.img" into the command prompt after and then press enter) then follow step 7).
Update: Linux:
C) Depending on kernel, for this sake we will use a debian based kernal.
This is how you download ADB and FASTBOOT for Linux: Open terminal and type: "Sudo apt-get install adb && sudo apt-get install fastboot"
4) Open terminal and type: adb reboot bootloader
5) Open terminal and type: fastboot flash recovery (and then click and drag newtwrp.img onto the terminal) and hit enter
6) Open terminal and type: fastboot flash boot (and then click and drag bootfilelistedabove.img onto the terminal) and hit enter
This applies towards both Windows and Linux: continuation after their last listed step written above.
Step 7) Remove battery from phone, in order to force a shut down.
8) Boot into Recovery-TWRP Mode.
How to boot into LG Aristo 2 TWRP Recovery:
a) The phone is off.
b) Hold the volume key and power key at the same time.
c) When the LG logo appears, let go of the power key (while still holding the volume down key) and then click and hold the power key once again.
d)You will be prompted to LG Aristo 2's stock recovery mode asking you if you are sure you would like to delete ur phone.
e) Go to the option "yes" and enter.
f) It will then warn you that can remove all data from your phone.
g) Go to the option "yes" and enter.
You will be in TWRP after this.
TWRP Mode:
9) In TWRP go to "Wipe > Format Data" and then type "yes" and confirm it. (Do not hit reboot, click back a few time and hit reboot > recovery)
10) In TWRP go to "Install > Select Storage" and select your SD Card. Then look for where you placed the "magisk" zip file. Install it.
Your phone is now rooted.
On TWRP menu: Reboot.
Restore your phone if you created an LG backup of your important files (like lets say contacts or applications).
-----------------------------------------------
If any mistakes were made and you phone becomes locked, here is how to go into download mode to repair your LG Aristo 2 into its default stock rom. Credit to @tecknight: https://forum.xda-developers.com/showpost.php?p=76837800&postcount=4
1) Power off phone.
2) connect usb to Lg Aristo 2 phone (without connecting the usb into the PC or laptop)
3) Hold volume up key and then connect USB into computer
4) download LG Bridge
5) detect phone
6) click on "Update Error Recovery"
Your LG Aristo 2 will be repaired and factory resetted.
-------------------------------------------------------------
What root means: In terms of PC language, Root means the superuser that has privileges to Add, Modify, and or Delete any kind of system files without prevention. Pretty much, it's like the actual Administrator account on a PC. Natively, whenever we buy a phone, it is as if to say, we are only using a guest account. Since the android OS is basically a Linux based computer (correct me if i am wrong) we can do anything we like... You want iOS emoji's on an android? A custom boot animation? Having root privileges allows you to go beyond your guest user restrictions because you then become the Admin.
Explaining the function of the provided Magisk app: It allows root privileges for programs intended for rooted phones.
There are other popular programs alternative of Magisk app, such as the SuperSU app: http://www.mediafire.com/file/2dljobq6yw93w76/UPDATE-SuperSU-v2.82-20170528234214.zip
--------------------------------
After being officially done setting up your rooted phone, make sure you disable OEM Unlock to avoid seeing the caution message before every boot.
--------------------------
How to backup your phone.
Also, using ADB, backup your phone.
Windows: Click and drag ADB file onto command prompt and paste " backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "
Linux: Open terminal and type " adb backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "
Update: For those who are encountering "Now unlock your phone and confirm operation" when typing the latter code, there is an alternative and much more easier and safer way to backup your phone.
Boot into TWRP and click on "backup" and then select what you would like to back up and then swipe to confirm the operation.
-----------------------------------------------------------------
Confirmed Successful rooting for LG Aristo 2 - June 2018
Thank You Brad and Tec!
Salam Aleykom.

Brad I have a question, is there any way to get a custom ROM on this phone? If not how come? How does it all work?
And are you with Metro PCS as well? What apps can a safely delete to get this phone as close to a stock version of android as I can? Can I seriously just wipe out EVERY metro app? Hows your phone functioning?

Until there is a custom recovery built, we won't have custom roms. Dont wipe out every metro app. Anything you arent sure about, look up, or just freeze the app and test results. My phone is fine except SuperSU wont work properly due to the binary being occupied, but this is the best we have so far. I debloated no problem.

Root is the only thing needed, not a custom recovery. Apps like Magisk Manager can flash custom images. The reason there is no ROMs built for this device, I can tell you in my opinion there is no need for a Custom ROM. Magisk Manager has plenty of customizations available as well as many other root apps. Basically, custom recoveries are obsolete, it is not needed for gaining root access nor flashing files. Magisk can do it as well as Flashfire.

Hey man, I would press the Windows Key+R and type" "cmd"
Then, as long as your adb is located at C:\adb type: "cd C:\adb"
Then use adb, I hate how Windows 10 forces it on users!
Hey, I am so sorry to bother you but when I enter in the fourth step of your tutorial, it tells me "flash boot" command doesn't exist. Is there something I'm doing wrong?

Okay, after messing around with it a few, I found that once it goes off into fastboot... my computer can't recognize it anymore?
brad2192 said:
Hey guys, spent a few hours figuring out how to root. Pretty Simple!
1) Enable Developer Options, USB Debugging & OEM Unlock
2) Reboot to Fastboot Mode (Using ADB via PC type: adb reboot bootloader)
3) Add root_boot.img into your adb folder
4) In ADB type: fastboot flash boot root_boot.img
5) After flash successful, type: fastboot reboot
6) Install Magisk Manager App
For those skeptical, proof of root here.

Do I need to unlock the bootloader first? I have it rebooted into fastboot and it's giving me instructions to do that, but won't let me push the boot image. If I do need to unlock it, does it wipe my device?

Yes, that is what OEM unlock means. In doing so you do need to unlock the bootloader.

Yes, when you use "fastboot oem unlock" it unfortunately erases all data. One of our forum members is working on a TWRP at the moment that might be available today. You could wait to do this so you can create a backup.

That'd be cool. But, wouldn't the bootloader still need to be unlocked for me to flash TWRP?

What are you typing into ADB to get that error?
Do you have to de-encrypt the phone for root? I am thinking of getting an Aristo2, currently using the MotoE4 (which I hate!), and rooting that requires de-encryption (I love encryption!). This is the MetroPCS version your talking about? Thank you...

"Cannot load Android system" after failed update - HELP!

My Android phone (Motorola Edge) can no longer start properly after a failed system update. The message I get is: "Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device."
I've tried restarting it in recovery mode which didn't work. I've read that I may be able to install some software via USB and rescue the system but I have no idea how that's done. I've looked at some different rescue software such as Rescue and Smart Assistant (which would only let me rescue the phone which will erase all data) and Dr.Fone but the reviews aren't convincing and the unofficial software programs generally don't support Motorola phones. Does anyone know how to fix my phone without losing my data?? Any help is much appreciated.
Also; I'm in no way a developer so I need everything explained to me like I'm 12 years old.
hi, kid welcome to xda.
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.

Thank you so much for your input. Unfortunately I can't make it work. When I type 'adb devices', I get this text:
List of devices attached
ZY227HQ2BX sideload
I've attached more info. Not sure if this has something to do with "USB debugging"?
all things right,
that sideload appears because you have stock recovery {no need to worry}
you don't need to erase system, (it is like optional)
and the error ANDROID_PRODUCT_OUT....... is because as i said earlier you have to copy the path of the file not file name.
how to copy path of the file ?
well, simple on windows, open the folder in which system file is present. and again open command prompt type (remember to be in fastboot mode in mobile phone)
fastboot flash {drag and drop system file from folder to command prompt}.
it should look like (but not the same, it is an example)
fastboot flash E:/newfolder/nexus/files/system.img
tell me if you face any problem (also include screenshots like you did, great right?)
What file is the system file in this folder?

Hi again, I've spent all weekend trying to figure it out but so far no luck.
I don't know where to find the system file in the folder I downloader (see attached photo in my reply above this). I also tried making a service-batfile with guidance from YouTube but it seems my phone is locked so it doesn't work.
well sorry i was quite busy so i was not able to reply.
first thing first do you need your data
if so boot into twrp. find twrp image for your phone then use command in fastbootmode
fastboot boot and drag and drop twrp file.
after successfully booting into twrp use option to backup and backup your data in any external storage like sd card.
after that run flash all.bat inside your downloaded folder.
i will completely wipe and reinstall your firmware.
then after it again in fastboot mode boot into twrp and restore your backup that's it.

What about your original suggestions - will they not work on a locked device? Fx this:
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.

What about your original suggestions - will they not work on a locked device? Fx this:
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.
