IMPORTANT | IMPORTANT | IMPORTANT | IMPORTANT | IMPORTANT
Backup any personal files because everything will be deleted! Make sure you have at least 50% battery remaining.
1. Unlocking the bootloader officially
This is the first step in voiding your warranty so is the point of no return. I've read in some places that you may be able to do this without voiding your warranty but I did not look into this.
WARNING - This will delete everything on the phone so make sure to backup important personal files.
i) Visit the official LG website to obtain a bootloader unlock file. First click the 'How to Unlock the Bootloader' tab and then the button 'Starting Unlocking the Bootloader' at the bottom of the page: https://developer.lge.com/resource/mobile/RetrieveBootloader.dev
ii) Sign up to a free developer account using a real email address (it's needed)
iii) Enter your IMEI number which you can find on your box, under the battery or by dialing *#06# on the phone. Keep this tab open
iv) On your phone, go to settings -> About phone -> Software info and then tap on Build number 7 times. Go back to Developer options under general settings and enable 'USB debugging' and 'Enable OEM unlock'.
v) Install the LG G4 drivers from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
vi) Download and install minimal adb 1.4 from here: https://www.androidfilehost.com/?fid=24521665358595410
vii) Browse to where you installed this and then right click and select 'Open command window here'. By default, this is in C:\Program Files (x86)\Minimal ADB and Fastboot
viii) Plug in your phone to your computer using a reliable USB port and cable (USB 3.0 doesn't seem to work). Enter "adb reboot bootloader" into the command window without quotations. Wait for it to reboot and then type "fastboot oem device-id"
ix) This fastboot command will return a character string. This is the Device ID which is needed to generate your unique unlock key. It will look like this:
Code:
Example Device ID (PC User)$ fastboot oem device-id
(bootloader)-----------------------------------------------------------------
(bootloader) Device-ID
(bootloader) CD58B679A38D6B613ED518F37A05E013
(bootloader) F93190BD558261DBBC5584E8EF8789B1
(bootloader)-----------------------------------------------------------------
To generate your unlock key, you will need to paste together the 2 lines of output into one continuous string without "(bootloader)" or white spaces. In the example above, the Device ID would be:
CD58B679A38D6B613ED518F37A05E013F93190BD558261DBBC5584E8EF8789B1
Paste this into the LG website form and confirm. It will email you an unlock.bin file which you need to put in the same folder as your adb.exe file.
x) Now enter "fastboot flash unlock unlock.bin" into the command window. This should take seconds.
xi) Now check it is unlocked. By entering “fastboot reboot” and waiting for it to reboot. Then enter "adb reboot bootloader" again and then "fastboot getvar unlocked" and verifying that the response is "unlocked: yes".
Your bootloader should now be unlocked.Keep this command window open for the next step.
Thanks to shimp208 for minimal adb http://forum.xda-developers.com/showthread.php?t=2317790
2. Installing TWRP Custom Recovery
This will install a custom recovery allowing you to make backups and flash zip files.
i) With your bootloader freshly unlocked, you can boot up the device and set it up. Go through the startup guide thoroughly without skipping as these settings are going to stay.
ii) Download the latest TWRP img file from https://forum.xda-developers.com/attachment.php?attachmentid=4387389&d=1515789045 and place it in the same folder as your adb.exe file and unlock.bin. Now rename it to lgg4-twrp.img without changing the file extension!
iii) Now also copy the lgg4-twrp.img file to your phone's SD card using a USB cable.
iv) Enable USB debugging again
v) Open up a command window again by Shift+Right clicking in the folder with adb.exe.
vii) In the command window, type "adb reboot bootloader". Wait to enter the bootloader and then type "fastboot boot lgg4-twrp.img" and hit enter. The device should now restart in TWRP but it is not installed yet.
vii) Once TWRP starts, select 'install' and then tick 'images' at the bottom.
viii) Find the lgg4-twrp.img file and select it. Then in the next menu select 'recovery' and swipe the bar at the bottom to confirm flash.
ix) You should then see 'Image Flash Complete' so can select back then reboot and system.
(If installing from an external SD card, go to 'mount' from the main screen and then tick to mount your ext SD card. Go back and continue as normal)
Thanks to TeamWin for TWRP https://twrp.me/
Thanks to Adam Myczkowski for TWRP install corrections.
3. Root
By now, you should have an unlocked bootloader and a custom recovery installed.
If you use snapchat, you won't be able to log in with a rooted phone. So it would be a good idea to install it now and log in. You remain logged in rooting and installing Xposed. Quicklink: https://play.google.com/store/apps/details?id=com.snapchat.androidi) Download SuperSU from https://www.androidfilehost.com/?fid=24369303960690845 and place it on your phones internal storage.
(this works fine but you can get the latest from here: http://forum.xda-developers.com/showpost.php?p=64161125&postcount=3
ii) Make sure you have USB debugging enabled again.
iii) Now with your phone on and plugged in, enter recovery by opening adb as before and entering "adb reboot recovery".
If you have problems, see the end of this sectioniv) Once in the recovery, hit install and browse to the SuperSU file we just downloaded.
vii) Swipe flash and then reboot into the system.
The phone should now boot and be rooted. If not, see the notes at the end of this section.
You can use https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck to verify if you have root.
• If your phone does not turn on then pull out the battery and USB cable and then put just the battery back in. Now Press and hold the volume down and power buttons together. Then first LG logo should appear. Now continue holding the down button but release the power button for one second and then press it again and hold.
You should now see a screen asking you to wipe everything. Navigate with the down arrow and press the power button for both screens. This should now take you to TWRP recovery and NOT actually wipe the phone.
• If you had a bootloop then follow the above steps to get into the recovery and then you will need to download the following onto the phone: http://forum.xda-developers.com/g4/development/stock-h815-20g-images-kdz-flashable-t3450503 [1.5GB]
Once in the recovery, you are able to connect the phone to the computer for regular data transfer in order to transfer the file. (I had problems with the microSD card so I would avoid it).
This system image seems to be missing the FM Radio, LG Remote and SmartSettings, Voice Recorder and Quickmemo apps. To get these back, go to general settings -> About phone -> Update centre -> App updates and download/install as necessary.• If you still could not get into the recovery at all then follow the unbrick steps below in section 6.
Thanks to autoprime for the system images [url[http://forum.xda-developers.com/g4/development/stock-h815-20g-images-kdz-flashable-t3450503[/url]
Thanks to Chainfire for SuperSU http://forum.xda-developers.com/showpost.php?p=64161125
4. Installing Xposed
i) Download Xposed from here: https://forum.xda-developers.com/attachment.php?attachmentid=3848457&d=1471691646 and place it on your phone or SD card
ii) Enter recovery using the methods shown before. (You can also now enter recovery using this root app: https://play.google.com/store/apps/details?id=com.antaresone.quickreboot)
iii) Use the recovery menus to flash the zip file. Reboot.
iv) Download and install the Xposed installer app, XposedInstaller_3.0_alpha4.apk, from the post attachment here: http://forum.xda-developers.com/showthread.php?t=3034811
Thanks to rovo89 for Xposed and Follow_and_Feel for sharing the G4 Xposed link http://forum.xda-developers.com/showthread.php?t=3034811
5. Installing Viper4Android (this breaks FM radio!)
WARNING - The FM radio app will not work after installing this.
i) Download Viper4Android from here: https://www.dropbox.com/s/lvcxffdqimbi78b/V4A_Poweramp_Lollipop_v3.zip?dl=0
ii) Place the zip file on your phone or SD card and flash it in recovery. Reboot.
iii) Open the ViperFX app. From the menu and install the driver.
iv) You need to get Viper4Android to run in enforcing mode so flash this zip in recovery: https://www.dropbox.com/s/k9cnruw2e1t1d4t/ViPER4Android-supolicy.zip?dl=0
Install it. Open the app and set selinux to permissive. Reboot.
v) Install BusyBox from here: https://play.google.com/store/apps/details?id=stericson.busybox
Thanks to the ViperFX developers and zhuhang for Viper4Android http://forum.xda-developers.com/showthread.php?t=2191223

Once all this is done and you're happy. It would be a good idea to enter recovery and make a full backup so that you can restore to the clean rooted state.
6. Unbrick Guide
If something messed up while flashing something and can't boot. Open up the recovery and restore your backup. If you don't have one, flash the v20d system image from an external SD card [1.5GB]. Download here: http://forum.xda-developers.com/g4/development/stock-h815-20g-images-kdz-flashable-t3450503
If you cannot get to the recovery then follow these steps:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
This shouldn't delete your data (no guarantees) but you will have to grant app permissions again and reapply any changes to system files e.g. root, viper4android, xposed ect.
If you have problems try this method instead:

7. Debloat
Here is a list of apps and services an XDA user has suggested removing: https://forum.xda-developers.com/g4/general/bloatware-tool-t3141890/post61509537#post61509537
Removing these won't break the phone but of course be smart about it; removing Weather will mean you don't have the weather app. I only removed Google apps I don't use and redunadant apps from LG.
You can remove bloat apps using the Titanium Backup app from here: https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup
I would advice you to make a backup of them first in case you want them back. It's the easiest way to get the apps back.
If you do need a guide for using Titanium Backup, head over to this excellent guide: http://forum.xda-developers.com/showthread.php?t=2717159
8. Battery Optimisations
The aim is to get maximum battery life without compromising speed, user experience, features or notifications.
(I'm just going to use the following space as a log of things I've done. I will tidy this up when complete. Please do suggest if any of these things are ineffective or detrimental.)
Read through this guide: http://forum.xda-developers.com/g4/general/guide-g4-lag-free-marshmallow-t3327878
1. Disable Activity Logs: General Settings -> About phone -> Activity Logs at the bottom.
Also try following the steps on here; users report better battery life: https://www.reddit.com/r/lgg4/comments/4fb4uf/psa_free_up_some_ram_up_to_300mb_and_maybe_gain_a/
2. Disable Smart Settings under General Settings
3. Disable Bluetooth and Wi-Fi scanning location service: General Settings -> Location -> Menu -> Scanning -> Untick both. (I honestly can't believe these exist. I wondered why I have bluetooth wakelocks)
4. Disable Open Wi-Fi scanning: Network Settings -> Wi-Fi -> Menu -> Advanced -> Untick Wifi notification. Toggle this on and off as it should also fix random white LED blinking.
5. Greenify 2.9 beta to enable aggressive doze.
6. Follow this guide for processor tweaks http://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557
Please note that this is my first thread and I'm not a developer. I hope the instructions are as complete and accurate as possible and they are what I followed for my H815 602. If there are any things I forgot or updates, please do let me know.
Superb guide. Thanks. Should be stickied.
Official LG don't unlock bootloader for H815P
Only europe is eligible for service
when i try to get my device id it just hangs at:
Code:
C:\ADB>adb reboot bootloader
C:\ADB>fastboot oem device-id
< waiting for any device >
any ideas?
running win10, with the drivers installed.
-LE-
found out the problem. usb3.0 does not work used usb2.0 and work flawlessly
On 6.0 Android is more secured and so to install recovery you have to either boot the recovery, flash custom kernel, then flash recovery or unpack boot.img from a custom kernel, flash it via fastboot, then flash recovery and lastly full kernel package in recovery. Better if you include this in your guide because many people will be asking "why my recovery is not booting?" and that's what we don't want. I've repeated this about 50 times or more and finally I will not have to.
Hi! Thanks for this guide!
Just found a "typo"
ii) Now with your phone on and plugged in, enter recovery by opening adb as before and entering "adb fastboot recovery". (You will need to enable USB debugging again)
I'm sure it should say "adb reboot recovery" : )
It could be worth saying that after installing root, there will be a boot loop or two, it even say so when you install the latest SuperSU.
I am also interested in your battery optimization, the most I've done so far is to disable NFC and location and disable some of my google account syncs that I don't use or use very rarely.

Thanks for the correction.
In addition to what you've done, I have installed greenify and hibernated Snapchat, Viber and Facebook apps. WhatsApp isn't hibernated.
I have the donate version and xposed so till gcm push notifications.
I haven't done anything else. I had better battery stats installed for a few days and I kept checking it and was annoyed that I'd always have ~30% awake time with the screen off. There were no kernel wake locks, it was just app alarms mainly from android and Google.
I was getting 4 hours SOT and 20 hours use out of the box. Now I'm down to 3 hours 30.
I really wish the Autostarts app would work but it has no effect: https://play.google.com/store/apps/details?id=com.elsdoerfer.android.autostarts
This would allow me to stop many apps from waking up everytime the connectivity changes or the screen is unlocked.
I have Greenify with the donate Xposed settings. Coalescing, Deep Hibernation and GCM push enabled only. Here are the apps I have greenfied:
Maps
Skype
Viber
Messenger
Snapchat
Whatsapp
Gmail with 1 Google and 1 Yahoo account
CF.Lumen
Lux Autobrightness
Spotify
Viper4Android in High quality mode. Enabled are playback gain control; Equalizer; Dynamic System; Fidelity Control; Auditory System Protection and gain limiter.
Is anyone else not getting any sound from the radio app? It starts and even tunes to frequencies with channel name and now playing I hear no sound through headphones or speakers.
I've tried removing the app and installing from the update centre again.
The NextRadio app is incompatible (even when sideloading the apk) https://play.google.com/store/apps/details?id=com.nextradioapp.nextradio&hl=en
Well, I tried to unlock the H815 Taiwan version (bought on Amazon as a USA unlocked cellphone... ) but is not supported.
Damn it!
thanks...
i am wondering: if I go to settings / general / backup&reset, and then LG backup and perform a full backup on my SD card, will I be able to restore it all after rooting and get the system as it was previously?

I haven't tried it myself but have gone with the tried and trusted TWRP backup: http://www.howtogeek.com/240582/how-to-back-up-and-restore-your-android-phone-with-twrp/
And ADB backup which also works without root: http://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
These work great; you end up booting exactly where you left off and even with browser tabs still open as you left them.
From my understanding, you would need to boot into the phone and then perform the restore in the LG app. So this would require a bootable phone. The only times I restore would be after bootloops. For general app restore and settings, I use Titanium Backup. This provides the added benefit of being able to restore on different phones.
just to update all of you: I did root my 20d g4 and LG backup managed to restore almost everything. All apps are back, but I needed to agree to permissions for all of them and some returned with saved data, some did not. For example, none of my BT devices were recognised, so I have to pair all of them, which is tricky for moto 360, since it needed to be factory reset. However, I am very pleased with how things went in the end.
Also, my phone was not recognised when rebooting to fastboot, it took me an hour of changing ports and drivers, but then I decided to install the driver manually via device manager (win 7). I made an educated guess and nailed it
Also, I had a really hard time unlocking the bootloader, because LG site kept providing "service unavailable" message, so I had to fool the server that I am in Singapore (like in this guide https://youtu.be/O64GfQORCaE )...
it is work for H815-L?
and i will be glad if you post a guide how to unlocking the bootloader without voiding my warranty
and how about a guide to unlock the free money printing machine in our G4s? LOL
warranty will be void
Question will this work on sprint variants
I've updated the Viper4Android install method. You can flash this zip file: http://forum.xda-developers.com/showthread.php?p=61242973#post61242973
This will allow you to run Viper4Android without having to set SELinux to permissive. This is better for security but I also had issues with the SELinux mode changing back so would sometimes have to reboot or reinstall the viper driver to get it to work again. After doing this, you don't need the SELinux mode changer app.
will this work on v20e?

Hi everyone,
This guide is intended for only snapdragon version of Lenovo devices which supports QFIL (Qualcomm Flashing Tool). For MediaTek Devices, you need different tools.
However, please understand that the device which I had to test in length was LENOVO K5 PLUS and thus, recovery, stock images and development is for K5 plus. As long as you have stock rom, custom recovery or custom rom of your specific device which you own, you can follow this guide for any snapdragon device but booting your device into DIAG mode might need different commands.

DRIVERS ARE MUST HERE
You can simply download all the drivers from post three and install them all. In case you have troubles, you can refer HERE for more details.
WHAT YOU NEED
1. DRIVERS
2. USB DEBUGGING
3. ADB
4. TOOLS & STUFF (all in attachments)
5. Little Common Sense
6. Zero Skills
USB DEBUGGING ON
1.Activate the Developer options (Settings> About phone> Device Information> to tap 7 times in Build number)
2. Enable USB debugging (Settings> Developer> USB Debugging)
3. Enable OEM unlock (Settings> Developer> Unlock OEM)
4. Done
SETUP A WORKING ADB
Download platform tools from here in attachment
Extract them to any location.
Navigate to the location where you have extracted platform.zip
Hold crtl+shift on keyboard and then use your mouse to right click on an empty area of the folder.
Select open command prompt here
An cmd window will open
You are ready to go
Alternatively,
if that does not work for you. Simply download the platform.zip and extract it to C:/platform-tools.
Rename platform tools folder to adb
Go to cmd from start menu
Type in these commands until you see C:\> in cmd.
You will need to type twice most probably.
Code:
cd..

then type the following once you are at C:\>
Code:
cd adb
You will be in ADB folder, which will be now like C:\adb>
Now you have a working adb
RECOVER YOUR BRICKED DEVICE
There are actually 3 methods in theory to recover your phone. However,I also found that sometimes you can not flash your device using download mode and in this case, fastboot mode is the only route which means you will need to use TWRP or find a method to go into EDL from fastboot. So after you brick your device, your device can present in the following states.
No recovery or download mode but fastboot mode
Download mode
Recovery mode
Phone goes into download mode on its own
Possible Solutions
TWRP Method if you have a custom recovery or only fastboot(tested and works)
QFIL (tested and works) if you can boot into download mode
Lenovo Updater (untested)
ONLY FASTBOOT ACCESSIBLE NO DOWNLOAD/ RECOVERY.
Phone goes directly into download mode but QFIL unable to flash at all. Need to find a way to boot into EDL. Currently under working. Check this here Gold for those who need to boot to edl from fastboot
Fail with status when trying to flash using QFIL
Code:
Download Fail:System.Exception: Failed to Switch to Emergency Download mode
at QC.QMSLPhone.Phone.QPHONEMS_SwitchToEDL()
at QC.SwDownloadDLL.SwDownload.SwitchToEDL()
Download Fail:Switch To EDL FailSystem.Exception: FireHose Fail
at QC.SwDownloadDLL.SwDownload.SwitchToEDL()
at QFIL.Tech.DownloadTech.SwitchToEDL()
Finish Download
Two ways possible. Flashed TWRP and it worked by restoring previous backup. Works like a charm
Fastboot to edl needs some work. If that could be achieved. It will be brick proof.
TWRP METHOD
Pre Requisites
Fully working TWRP with root (preferable)
backup of your device (highly recommended) or download stock flashable roms HERE
STEPS
Boot into fastboot mode (bootloader) by switching off your phone and then press volume - and power
Flash TWRP recovery using fastboot commands HERE
Flash your previously made backup using RESTORE function in TWRP
To flash recovery partition, you will need to select flash IMG instead of preset ZIP when you navigate to INSTALL. You will find it on lower left side
DOWNLOAD STOCK RECOVERY FOR YOUR DEVICE HERE
You will need to unroot your device as well from supersu settings if you want to return to FULL STOCK
In case you only have fast boot mode and no recovery AND no download mode
Pre Requisites
You must have a fully working TWRP and possibly rooted
flashable zips of your stock roms or any previously made backup
STEPS
Simply place your update.zip in your sd card if you are using stock images
Or you can copy your previously made TWRP backup in sd card
Restore using TWRP if you have a backup
or flash via TWRP if you are flashing stock Images
Done
I highly suggest you wipe your device in TWRP including system
QFIL METHOD
Download stock image for your device. Make sure you choose the correct file for your device or you can hardbrick your device
Install QPST and QFIL software from attachments.
You may need to install Microsoft Tools which are provided in attachment for QPST to work
I assume that you have already proper drivers installed
Extract your device stock images in any given location of your choice but prefer it like D:/stock images etc
Open QFIL from start menu
Refer to image attachments 1,4,5,6,7 for the next steps
Browser Programmer Path and navigate to where you have extracted stock images.
Select the file with the given extention .(firehose)
Next load XML file and select the image.
It will ask for another file which you will be able to locate in the same folder\
Connect your device and see if the port is detected as QD LOADER
Select DOWNLOAD under LOAD XML
Sit back and enjoy. It should take 5-10 minutes
NOTES FOR QFIL
Bootloader Method does not seem to work. Even after changing drivers and replacing them.
Works with keys too. Hold Volume + and power after switching off device and select download!
Requires EDL method
Lenovo Serial driver required
Adb reboot edl
Then install drivers for Qualcomm port
Flash as instructions
Erase Misc after flash
Wait for device to turn on
STATUS : COMPLETE
Last updated 26.08.16
EFS
Pre Requisites
Installed drivers. ( See Next posts for detailed guide.)
Enable USB debugging. See first post
Working ADB (Download from attachment)
You will need to move to the location where you have extracted adb.zip
Hold crtl+shift + mouse right click and select open command prompt here and then you can give commands.
Root
[*] Recovery
TWRP BACKUP
I find this method most superior to all others.
Download recovery from this forum. All credits to the developer to make it possible
DOWNLOAD IT FROM HERE. TWRP WITH EFS BACKUP AND MORE
After downloading the recovery, using a working adb. Enter commands
Does not require root
Code:
adb devices
adb reboot bootloader
fastboot boot LenovoA6020_TWRP-3.0.2-r3_7M.img
You will boot into recovery with Russian translation. Change translation to your local language as shown in attachments TWRP 1 and TWRP 2.
Make EFS and all other backup and keep it safe.
I suggest you copy this to your PC before you plan to do something else with your device.
Done
Enable DIAG MODE on your device using adb.
Code:
adb shell
su
setprop sys.usb.config diag,adb
Once your phone is in DIAG mode, you can utilise these methods for QCN.
QCN is a file that holds all your data regarding your signals, bluetooth, wifi, imei etc
If you lose it without a back, it may be very hard to fix your phone.
For first two methods, you need to be in DIAG mode. For the last two, you can make a backup on your mobile. All four methods require root.
QCN EXTRACTION BY QFIL
Simply open QFIL on your PC.
You will see
QPST>Tools> QCN backup and Restore.
Select Backup in your desired location
Done
QCN backup by QPST other tools.
1.First time you are trying to make a backup of your QCN using this method, you will need to add DIAG port which you enabled via adb commands in QPST.
For that , go to QPST>BIN>QPSTConfig. You might need to go to show all ports before you are able to add it.
2.Next go to, QPST > Bin> QPSTServer.exe
3.A globe would appear in taskbar. Click on it and select software download from the tab
4.Select port of your diagnostic mode in backup tab of software download.
5. Once in software download, backup your current QCN
4. Done
Backup by blocks
This is a better method to make a backup. You can either use adb commands or simply download PARTITION BACKUP APP from play store. This will automatically backup your partitions.
PARTITION BACKUP TOOL PLAYSTORE LINK
XDA FORUM LINK FOR ANY QUERIES
These are ways to check your device for partitions manually. You can make backup of these yourself as well.
Detailed guide is given here
Code:
adb shell
cat /proc/partitions
[B]OR[/B]
adb shell
ls -al /dev/block/platform/dw_mmc/by-name
make sure you replace dw_mmc with your device partiton. (I have not checked it yet)
[B]OR[/B]
adb shell
cat /proc/partitions
adb remount
adb shell "su" "" "mount -o remount,rw /system"
adb push parted /system/bin/parted
adb shell
chmod 0755 /system/bin/parted
parted /dev/block/mmcblk0
print
Backup by tar.gz and Img
For this method you will need to download EFS BACKUP from playstore and then you can make a backup. I recommend make backup in all three formats.
EFS BACKUP PLAYSTORE
XDA FORUM LINK FOR THE APP
That's all you need for a good EFS Backup. Good Luck!
DRIVERS GUIDE
On Windows, it will automatically detect all drivers.
Make sure your device is attached to PC, before you install these drivers.
You may need to download drivers for ADB and QDLOADER which are all provided in Lenovo Usb driver.
So Installing these driver will be enough for you and you may need to manually select drivers for rest from lenovo folder
For ADB drivers use LENOVOUSB DRIVER 1.1.16 if your device is not detected by Windows.
For QHUB drivers use these in attachment named QDLOADER HS USB DRIVER.
Simply Install them and you are good to go.
INCASE YOUR DEVICE IS NOT DETECTED
All drivers are contained in these folder C:\Program Files (x86)\LenovoUsbDriver on your PC.
Go to My computer> Properties? Device Manager and see if you have any unknown devices like shown in attachment.
If you have, then I suggest you install manually.
Select unknown device and go in its properties.
Next go to drivers tab and select update drivers
Select Browse my computer for drivers
Let me pick from the list of devices
Select have disk
Move to folder C:\Program Files (x86)\LenovoUsbDriver
You will see that there are many folders.
ADB contains all ADB and Bootloader drivers
Use ADB folder if you are installing drivers for adb / fastboot/ bootloader.
Make sure you have usb debugging and device connected when you are installing these drivers. You have to be in normal mode for adb drivers
.
You can check if you have working adb by typing
Code:
adb devices
To download fastboot / bootloader drivers, simply first boot your device into fastboot.
Turn off device
hold power and volume down
Now try to install fastboot drivers
Serial Contains EDL drivers (Download mode drivers)
Select unknown device and go in its properties.
Next go to drivers tab and select update drivers
Select Browse my computer for drivers
Let me pick from the list of devices
Select have disk
Move to folder C:\Program Files (x86)\LenovoUsbDriver
You will see that there are many folders.
Use Serial if you are in download mode / EDL mode.
Working adb is required for this
You can go into EDL mode directly from adb commands by
Code:
adb reboot edl
OR
You can power off device
hold power and volume up
Select download mode and you are in EDL/ Download mode.
Now you can install drivers from above method
Make sure you select QDLOADER 9008 while installing EDL drivers.
How to enable QHUB drivers if no unknown/ undetected device is seen
Sometimes, your device is not detected in QFIL and you have all drivers installed and there is no unknown device in my computers> device manager.
For this, you will need to attach your device first.
Go to Device Manager by going into my computer properties
Look for ADB Interface drivers in device manager.
Update drivers for ADB interface and replace it with QDLoader HS USB driver.
If it asks for any permission, allow it.
In case your windows do not allow you to install these drivers , you need to turn off Digital Signature Verification in windows
run cmd as run as administrator
Type in these commands
Code:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
Restart
Then try again to reinstall drivers
To re-enable device verification on Windows
Code:
bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING OFF
Good luck
ROOT AND TWRP
HOW TO ACTIVATE USB DEBUGGING
1. Activate the Developer options (Settings> About phone> Device Information> to tap 7 times in Build number)
2. Enable USB debugging (Settings> Developer> USB Debugging)
3. Enable OEM unlock (Settings> Developer> Unlock OEM)
4. Connect the phone with the USB cable to the computer
5. Install the drivers that come on the CD cell partition.
TWRP:
Download TWRP from HERE or TWRP WITH EFS BACKUP AND MORE
Copy it to the folder where abd is installed.
On working adb, type in these commands
Code:
adb reboot bootloader
fastboot flash recovery LenovoA6020_TWRP-3.0.2-r3_7M.img
OR
fastboot flash recovery TWRP-k5-3.0.2-r2_shreps.img
This will permenantly flash twrp instead of Stock recovery.
If you just want to boot it once. check backup guide by using this command instead
Code:
fastboot boot <file name>
ROOT
Download the ZIP file SuperSU v2.76 and save it in the micro SD card.
Restart the phone in recovery mode:
Turn off the phone, then turn it on while pressing the volume up button. a screen appears with various options and choose "recovery".
You can even boot by adb commands using
Code:
adb reboot recovery
[*]
When opening the recovery, select Install and locate the file you downloaded just now.
Confirm execution flashing, restart the phone and voila!

BACKUP GUIDE
I HIGHLY RECOMMEND TO BACKUP YOUR DEVICE BEFORE YOU NEED TO EVEN ROOT YOUR DEVICE OR FLASH TWRP . IF YOU FAIL TO DO THIS, YOU WILL HAVE TROUBLE UPDATING YOUR PHONE VIA OTA ESPECIALLY IF YOU ROOT YOUR DEVICE
THIS IS MUST AS YOU CAN ALWAYS EASILY REVERT BACK TO YOUR ORIGINAL STOCK STATE IN CASE YOU NEED IT.
Download TWRP from HERE or Download recovery from this forum. All credits to the developer to make it possible DOWNLOAD IT FROM HERE. TWRP WITH EFS BACKUP AND MORE
YOU DO NOT NEED ROOT
I suggest you use the second TWRP as it supports more partitions than the first one.
Open working adb
TYPE IN
Code:
adb devices
adb reboot bootloader
fastboot boot LenovoA6020_TWRP-3.0.2-r3_7M.img
OR
fastboot boot TWRP-k5-3.0.2-r2_shreps.img
You will be booted into recovery.
Select Read only mode
Go to backup
Backup all partitions by selecting all of them
Swipe to confirm.
Make sure you have about 6GB for a full backup
You can skip user data if you do not want user apps backup
Nothing will be changed unless you enable system modification. So on first boot, simply do not enable system modification and go to backup and then backup all partitions. Keep these safe in case you need them.
Keep it in a safe place

C:\Program Files (x86)\LenovoSmartAssistant\LenovoSmartAssistant\plugins\75fc9be6-29e6-495f-8c0a-93f9e1971133
Extract it and find system.zip and your country ota (both) in the sequence
Country.ota.zip (image taken from QPST)
Country2Default.ota.zip (image taken from QPST)
System.zip (image taken from FullOTA)
Does not flash with no error but system not updates and shows update again
Must flash system using QFIL
I used Indian firmware as I couldnot find for my region and thus I always had the error. Can not switch carriers.
I went to recovery and then 0>OTA> Flashed India OTA
Checked for system updates and this time it worked fully.

Just to remember you guys, these methods DON'T WORK on A6020l36. Don't try this on your phone if it's this model, but if you did (like me), here is how to unbrick your phone.

Well, I have not tested this with a XIOAMI device with QFIL. In theory it should work, but I have always preferred MIFLASH as it is designed specifically for Xiaomi devices. Most of snapdragon devices has an emergency download mode.

What do you mean ? QFIL should work on all lenovo devices (snapdragon) provided you have proper stock images which are specific to your device. Google is your friend ? TWRP and development is not currently my aim for any device yet. As i did all my experiments using a K5 plus so I could write in length about it specifically.

Thank you for your time man! Twrp does not work with my phone (I mean, I can install it, and root/flash some stuff, but it definatelly does not work for flashing any of the images uploaded here, including the backups or the pac/cyanogenmod roms, they all give the same compatibility erros as the roms were not made for this phone). I followed the instructions, wiped system/data/dalvik, tried to flash, compatibility erros. There is no way of backup too, since it crashes at the ending. I'm starting to think that my phone is not the a6020l36 (even though it says that on a label under my battery, on my phone's setup and also on the box), but some variant made for my country only. And I know that are brazillians that claim to make it work on their phones, but since there's no way to guarantee that we really have the same phone, I don't now what to do. The QFIL stock rom (that I got from another place too, the ones uploaded here don't work either (another reason to think that my a6020l36 is different from the ones people claim to work here)). Thank you again for your time.
Hey Guys. This guide will help you if
1. If Using Custom Rom and want to revert to latest stock rom.
2. If Stock Rom got corrupted or became laggy.
3. You want to reinstall stock rom.
Warning:
1. Method 1 require unlocked bootloader. If you want to unlock then go Here . Method 2 doesn't. Don't worry.
2. This will clean your phone just like new phone.
3. First read the post twice carefully then proceed.
4. ALL .bat FILES TO BE RUN IN FASTBOOT MODE ONLY, IF YOU DON'T KNOW ABOUT FASTBOOT MODE THEN GOOGLE "HOW TO GET FASTBOOT MODE IN ASUS ZENFONE 2
5. I may change name of files in folder. Use common sense to identify them.
Pre-requisites:
1. Charge your phone atleast 60%.
2. Backup any important data you might not wanna loose to either sd card or usb drive or pc.
3. Copy the rom zip in the sd card of your phone. (The one with size in GB)
4. Android USB Driver should be installed already, if it is not then install all drivers in the "Drivers Folder".
5. Enable USB Debugging.
For that go to "Settings" ,Scroll to bottom goto "about", goto "Software Information", tap "Build number" upto 7 times or till it
says "You are a developer now". Then go to "Settings" you will find "Developer Options", open it and enable "USB Debugging"
4. Common sense, patience.

FAQ
1. Having problems with device connection? like waiting for device.
Sol. Make sure you have enabled USB Debugging (Not applicable for BL Unlocking and TWRP Flashing)
Uninstall all drivers previously installed on computer(every driver of any device)
Reboot your computer. And then install all drivers given in the driver folder.
If the problem persists, try different computer and different usb cable.
2. Facing permission denied in fastboot mode or while running script files.
Sol. Try disabling your lock screen security to none.

Thanks for suggestion. But the reasons are
First thing is stock raw image of latest version is very difficult to find.
Second thing sometime asus flash tool stops responding. So you have to wait again for 30 minutes. Also it doesn't show progress sometimes.

Hello, my 551ml has stock LP, it's rooted with bootloader unlocked and Xposed installed. If I want to install the latest MM with through the raw flashing tool, should I install the MM bootloader first or it is included into the raw file? Thank

did you find any?
i want to remove the lineageos and install latest stock LP but i have no clue how to do it
I have a LG K20 plus with t mobile as the carrier. I believe the model should be TP260. I mistakenly restored a twrp backup from a metro pcs phone that I got from this site coincidentally. Now my phone drops calls and data frequently and shows metro pcs on bootup vs tmobile. I have a kdz file but it won't flash because it now also thinks the model is MP260...not TP260 and says it's a mismatch. Any ideas on how I can get a restore for tmobile to try to reset the phone?
Just bumping
i could use a restore too. I installed super SU root and lost access to android pay. I wasnt to try that magisk root
I restored mine with the linked files.
install LG driver (uninstall any other drivers first)
install LGUP
remove battery from phone and replace
hold volume up key
insert USB while holding down volume up key
phone will boot to download mode
drivers will find phone
run UPPERCUT.exe
UPPERCUT.exe will launch LGUP with phone connected. if phone is not connected try again.
in LGUP lower window browse to TP26010k_00_0316.kdz
choose UPGRADE option in LGUP
click START in LGUP
factory ROM and Recovery will be installed, bootloader will still be unlocked
https://drive.google.com/open?id=0BygTApD1iNSSb3pCcU9RRlV1MVE
magisk can be installed using the same method as superSU. Mine is working along with AndroidPay

You were able to install TWRP after this process with the TP26010k_00_0316.kdz?
I am on TP26010E and don't want to upgrade to TP26010k if TWRP cannot be flashed as it has been stated here.
Yeah, you have to perform OEM unlock again, but I have been able to flash TWRP after flashing the previously attached .kdz with the LGUP tool

Can I install this kdz from twrp and install supersu?
no, you have to use LGUP tool. This is a LG image that will flash everything including your recovery partition, and not a flashable ROM image.
You flash root through TWRP, you use LGUP for kdz as the user above said rom flashing and kdz flashing are two different things
See this post which reflects the new kdz available https://forum.xda-developers.com/showpost.php?p=73690098&postcount=3
Just a Heads up there is a new version out, as of 9/01/17
MP26010r_00_0817.kdz

I flashed the modded ROM for MetroPCS, and couldn't flash kdz file because my phone was identified as MP260, instead of TP260.
I wiped the phone and re-locked the bootloader, and the phone would only boot into download mode, It gave a message about it being corrupted.
I took it back to TMO, and the sales people thought it was a virus, and replaced the device.
I've made a TWRP backup for anyone who runs into the same problem. This will fix your problem, so you can use the flash tools available for this device.
NOTE: I also provided Root tools and instructions for those Rooting for the first time.
1. Power off device, plug into computer, then hold volume up for download mode and let COM drivers install, you may need to change COM port to 41, through device manager.
2. In LGUP, choose upgrade or FOTA upgrade.
2. Once you flash firmware, you'll have to hit reset once or twice to get rid of the encryption failure notification.
3. Enjoy rooting your device again if you so choose.
ROOTING:
NOTE: Must have ADB & Fastboot setup already.
First you must unlock your bootloader.
1. In about phone settings, tap build number 6x to get developer settings, enable adb debugging and OEM unlock. Now plug into your computer.
2. Boot into Fastboot mode.
A. Open command prompt and type: adb reboot-bootloader.
B. Next type: fastboot oem unlock.
WARNING: You'll be prompted to factory reset device to protect your data. Your chance to turn back, if your brave then continue. Your device will factory reset, and you'll have to perform the first step again and you'll be ready to root.
1. To flash TWRP, plug into computer, then in command line navigate to where you have your recovery.img
A. adb reboot-bootloader
B. fastboot flash recovery recovery.img
2. Pull battery and manually boot into recovery,
A. volume+down as soon as you see LG, release then press again quickly and hold, follow the steps provided.
3. Hit cancel for the encryption notice, and swipe to modify system.
4. You must format device to get rid of encryption message, so choose format and it will ask you to type, yes.
5. Stay in recovery and flash the no-encryption.zip, and Magisk, if you choose to use it for your SU manager. Stay in recovery.
6. Reboot into recovery, and then set up your TWRP environment.
7. Enjoy Root:laugh:
NOTE: If you decide to root again, try using Magisk for SU management. Magisk's mods are excellent, and can run along side Xposed. If you choose Magisk, do not flash SuperUser.zip

You could probably flash the TWRP back up. After that your device would be Identified as TP260, by the flash tools and you'd end up with the same issue I had, when you decided to go back to stock, so make a TWRP backup on external memory. The KDZ file most likely won't flash because it performs a DLL check, to match device with firmware.

I've got backup after unlock Bootloader and before root. Pretty sure it's got recovery on it. I always make a backup asap. It's the mp26010t (I had the November patch but some reason after root it says Oct).
Is that what you need?
Pm me if this is what you need and I'll send you a link
I have a Metro LG K20 Plus phone and want to change the firmware to T-Mobile. I have not been successful doing this as I always get invalid firmware, because LG UP recognizes the phone as a metro phone. Is there a way to succeed in getting the T-Mobile firmware on the phone?
thanks in advance.
lg k20 plus tmobil
lgup recognizes my model correctly as lg-tp260 on [com41] but it just sits there initializing for eternity. With my model highlighted I select it and I keep getting the error "LGUP cant load the model [C:\Program Files(x86)\LG Electronics\LGUP\model\com. I have installed lg air drive, lg bridge, lgup8994.dll, lgup for store. I desperately need to get this thing back to stock, I have the AICP rom installed but I dont like it. it was a mistake, if anyone can help I would appreciate it.

Could you PM me this link to the Metro PCS stock backup, if you still have it?
Hello everyone. Meanwhile you excuse me for imperfect English but I use translator, my English language is rusted...
I have a A2017G, I have managed to unlock the bootloader, install TWRP and SuperSu on 6.0.1 version But then I have had the nice idea to update to 7.1.1 then have put update. zip file (renamed), in SD card, turn off the terminal, enter into TWRP but it Disappear!!! Only Originale...io recovery make flash and device updated to B09.
I want to install TWRP and SuperSu and put alternative ROMs but I can't do anything! If I open PowerShell window in adb folder and command "ADB reboot bootloader", the device reboot and appear a screen where to " your devices software can't be checked for corruption, please lock the bootloader", ecc ecc, If I squeeze volume on, it will get into recovery, if I don't do anything it reboot normally.
I can not get into fastboot mode, I fail to install TWRP. What is the best way to go back? or reset everything and start again? I have tried to downgrade from Nougat to MM via SD but after about 1 minute of analysis I aborted the installation....
However the phone will work normally even without all these things but I have purchased ZTE for modding and I don't bear to have half fatto...in work the most difficult thing to be unlocking the bootloader and I do this thing...
Let me link you my ingenious, allmighty Axon 7 Companion Thread.

Your phone works normally
You don't have fastboot
You have stock recovery
If this is the case then most surely you have EDL working...
Install TWRP from EDL mode:
This is taken from Controllerboy's guide
BE SURE THAT WINDOWS SHOWS FILE NAME EXTENSIONS!
A) Flashing TWRP Recovery to your device.
Q: Why do I need TWRP?
A: TWRP is a custom recovery system. It lets your backup your system in case anything goes wrong. It also lets you flash custom ROMs and zip files containing patches like viper4android or A.R.I.S.E. (audio) and root your device via SuperSU.
0) Boot up a windows computer with a 64bits processor. Verify your Axon 7 is charged at least 75%. Temporarily disable your antivirus software to allow axon7tool to work.
1) Backup all the data of your phone's internal memory that you don't want to lose. Copy it to your PC
2) Download the axon7tool from here: http://www.filedropper.com/axon7tool-15-win64
3) Download minimal adb and fastboot from here: https://www.androidfilehost.com/?fid=457095661767103465
4) Unzip the minimal adb and fastboot file, place the folder with the files in it somewhere you can easily find it
5) Place the axon7tool exe in the same folder as adb.exe and rename it to "axon7tool.exe" (it's easier to work with that way)
6) Download the TWRP .img and .bin files from here: https://drive.google.com/open?id=0B4...nlaZU1NRldoRjA
7) Place the TWRP .img file in the same folder as "adb.exe" and "axon7tool.exe", rename it to "recovery.img"
8) Make a copy of the "recovery.img" file and name it "recovery.bin". Leave it in the same folder
9) Go to settings in your phone and go to "About Phone". Tap "Build Number" 7 times to make the Developer Options available
10) Go to "Developers options" and tick "Allow OEM unlock" and "Android Debugging"
11) Connect your Axon 7 to your PC
12) Open a command window by holding shift and right-clicking in a blank space in the folder where the "adb.exe", " axon7tool.exe", "recovery.img" and "recovery.bin" files are located. Click "Open command window here"
13) Type "adb devices" and hit enter. You should see one device with some code listed
14) Type "adb reboot edl" and hit enter. Your device will reboot to EDL mode. It appears to be off, but it is in fact in EDL mode.
15) Go to Device Manager on your pc and verify your Axon 7 is listed as "QUSB_BULK"
16) In command, type "axon7tool -r gpt boot recovery" and hit enter
17) After it is executed, your phone will reboot. Wait until it has fully booted.
18) In command, type "adb reboot edl"
19) Verify you now have 3 backup files in your ADB folder for gpt, recovery and boot. These are backup files in case something goes wrong
20) In command, type "axon7tool -w recovery"
21) Wait until it finishes
22) Your phone should reboot
23) Shut down your phone and boot it to TWRP by holding both the power and volume up button to verify you have TWRP
24) TWRP might ask you for a password. If it does, simply tap cancel. It will ask you if you want to modify system. Swipe to agree
NOTE: if you have problems connecting to your phone as QUSB_BULK, download Zadig and replace your drivers with WinUSB ones. If axon7tool doesn't recignise your device even when connected as QUSB_BULK, try killing adb.exe via task manager before retrying.
Hello and thanks for the guide.
I have tried this system... be gone everything OK up to number 16... when I type "Axon7tool -r gpt boot recovery ", the command window should be written "Failed to connect "... and yet the device is in EDL mode.
Be all right, on Device Manager be seen as "QUSB_BULK ", the cable being original, all steps 1 to 16 be ok...io no longer know what to do.

Easy. Hold all 3 keys (power, vol up and down) until Device Manager refreshes (you'll see it as the list of devices contracting), and close CMD. Open it again and do step 16 again

Hello and thanks for the advice. Unfortunately it does not change anything.. I have done exactly as you say but the result does not change anything...io have connected the device, Open command window, type "adb devices ", is viewed as "Cd07b2e9 device ", I type "adb reboot EDL ", it restarts in EDL, then go to management Devices and is viewed as "QUSB_BULK ", Run command "Axon7tool-r GPT boot recovery " but it says "Failed to connect ", then I'll return to Device Manager, hold volume up & Down & Power, Icon disappears and returns after a few seconds, close window and launch command "Axon7tool-r GPT boot recovery " but still give "failed to connect "...
So, recapping: I have bootloader unlocked, I can get into EDL but PC does not see device although on Device Manager it exists...
I now launch device into the wall... problem solved.
if you really slammed it against the wall, i would love to buy the back housing and speaker grills. hopefully, you were just illustrating frustration (it is a frustrating scenario), and will reach a resolution, but if you actually did smash it, i could use some parts.

Of course I'm kidding... have just purchased this device, have a great hardware but the software does not go well for nothing. I have had a dozen phones, I changed about 60 ROMs, so for me it is not difficult to change the software...ma in this case have problems. Is it possible that I fail to solve this problem? Be a way to reset everything and start from scratch? Okay, the bootloader be unlocked but not be any other way to go back? I have seen many guides but not able to solve the problem. I fail to make flash of TWRP, fail to do downgrade to MM....io hope someone help me... thanks.
are you using a USB 2.0 or 3.0 port? it may not apply to this scenario, but with Motorola and RSD Lite, I always had to use usb 2.0 ports or it wouldnt see my device when flashing.
also, the steps @choose an username listed out are the best way to start from scratch, but obviously you have to be able to have your computer see the phone in the desired mode.
@DrakenFX has several guides in the axon 7 forums that should help once the computer sees the phone as well.
I use USB 3.0 with original cable ... but if you now tell me that maybe this is my problem, then I use USB 2.0. Thank you...
Good morning...
Nothing to do... I put the original cable on USB Port 2.0, have redone procedure from window PowerShell, on command "adb devices " Everything OK, on command "adb reboot EDL " It enters EDL mode, but then all the procedures are failed... if command "Axon7tool-R recovery GPT boot "I always get out of the inscription " Failed to connect ", it remains in EDL and I just have to reboot... I replaced the drivers with Zadig 2.3 but did not change anything... are there any other moors to make flash of TWRP? exist lthough an app that do this? I remember that for LG G3 I'll fix everything with an app...
