I am NOT responsible for what you do to your device either, so follow these instructions at your own risk. Make sure you know what you're doing, it's best to understand the process rather than just copy and paste commands and such.
This method uses a firmware flashing tool to install TWRP, I am
using QPST to install it, but you can use any Qualcomm firmware flashing tool.
1. Download and install the following:-
->Adb and fastboot driver
->QPST
->Your device’s pc suite
2. Download the latest official firmware and the latest TWRP recovery for your device. Extract the downloaded firmware.
3. Go to ADB folder in C drive and press “shift + right click” and click open cmd shell here or powershell in case of windows 10.
4. Connect your phone to pc and type: adb reboot edl
now your device should be rebooted into download mode or edl mode.
5. Rename the downloaded TWRP to recovery, copy it and paste it in your extracted firmware files and click replace.
6. Open the Qfil flashing tool.
7. Select flat build and click browse in select in programmer path, click all files and select prog_emmc_firehose_XXXX_ddr.elf from the firmware folder.
8. After all done click Download
9. Done you have successfully installed twrp without unlocking the bootloader.

Is booting to edl mode working? I've read it's not accessible by users in one of comicsdans thread
Anyone tried this? I was unsuccessful. My phone reboots to system instead of edl. Trying it in fastboot mode doesn't help. QFIL has the "download button" inactive. Any thoughts? Thanks
Try booting into edl from Windows using command similar to adb reboot edl. Should work.
Links required
Kindly provide the download links
No edl mode for the poco f1 , you have to use the test point method for this
Is edl mode the same as Download Mode?
In that firmware folder there are no files by the name that was given nor there a edl mode. If I go into fastboot (download) mode the program doesn't pick up my device
Will it work for every device or just poco..?
Please reply
Can you also provide a video here . I was unsuccessfull in installing it and almost ruined my phone .

A lot of people have been asking, so here are my notes for gaining root w/o flashing or unlocking the boot loader. :good:
Thanks to Chromium and The Jack of Clubs for their initial concepts and documentation.
Download ADB and set up Tools
Download the full Android SDK here:
http://developer.android.com/sdk/index.html#download
(scroll to the bottom of the page -> DOWNLOAD FOR OTHER PLATFORMS -> SDK Tools Only)
Extract the android-sdk-windows zip to c:\android-sdk
Browse to C:\android-sdk\android-sdk-windows\
Double Click and run SDK Manager.exe
Uncheck everything except the Android SDK Tools and Android SDK Platform-tools
Hit the Install xx Packages button
Download Super SU and TWRP
Download the latest TWRP here:
http://techerrata.com/browse/twrp2/bacon
Extract the TWRP image file and save it as recovery.img in the following folder:
C:\android-sdk\android-sdk-windows\platform-tools
Download SuperSU here: http://download.chainfire.eu/452/SuperSU/UPDATE-SuperSU-v2.02.zip
Plug your phone into your computer and Copy SU zip to the phone... (anywhere will work)
Get your Phone into Fastboot
Reboot the phone in fastboot mode (hold volume up + power). You should get a cyanogen guy smiling at you, this indicates the phone is in fastboot mode.
Open a command prompt and do:
cd C:\android-sdk\android-sdk-windows\platform-tools
Type:
fastboot devices
NOTE: You should receive a list of connected devices, this means your PC is connected to your phone. If not, something is wrong with ADB or your USB driver and you need to fix it before you can proceed!
Boot with TWRP and Flash
If “fastboot devices” worked without error, type this:
fastboot boot recovery.img
After the recovery.img transfers, your phone reboots into TWRP. Hit “Install” and choose the SuperSU.zip from the location on your phone that you saved it to earlier.
Once flashing is done, reboot and enjoy root. No re-imaging or unlocking your bootloader necessary.

Ah ok, i did unlock and switch to PA after second boot , so there were no data that would be lost
May I ad that there is an easier way to get adb. Its a program called minimal adb. This what I used originally in case someone prefers to just download that file. Just an option thats all... :good:
Nice tutorial
Download
Search for TWRP recovery for LG V10 H901 (File: twrp-2.8.7.0-h901.img (31.7 MB))
Backup Apps and Data
While this process should not wipe any of your data, a backup is highly recommended. Once you install a custom recovery like TWRP, make sure you backup your system, data,etc. from the recovery. It will be helpful in case anything goes wrong.
Prerequisites
This guide is compatible with LG V10 H901 only. Do not try it on any other devices or variants.
Unlocked bootloader is required to install a custom recovery like TWRP on your device. Click here.
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
Install Motorola USB Drivers on your computer.
Open Settings> Developer options and enable USB Debugging on your device.
Go to Developer options and enable Allow oem unlock.
How to Install TWRP Recovery on LG V10 H901
Download the recovery image file. Extract if in case a zip file. Now transfer the file to your PC where you can easily locate it.
Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.
Now power off your device and unplug it from your PC.
Boot into the bootloader or fastboot mode. To do so, press and hold volume down and the power button simultaneously for 5-6 seconds. When you see the bootloader screen, connect your device to the PC using a USB cable.(Choose fasboot if option is available) Alternatively, you can also issue the following command through your cmd or terminal, while connected to the PC in order to boot into the bootloader.
"adb reboot bootloader"
Navigate to the location where you have placed the recovery file. Rename the recovery file to a simple one, like recovery.img. While the folder with recovery.img file is open, hold shift key on keyboard and right-click on an empty space and select “Open command window here” option to launch a cmd window.
Now issue the following command in the command prompt to check your device connectivity
"fastboot devices"
Now flash custom recovery. Issue the following command for that.
"fastboot flash recovery recovery.img"
Custom recovery will now be installed on your device. Now boot your phone in recovery mode. You can do this by turning your device off and then press and hold volume down and power keys at the same time. Or you can simply enter the following command.
"fastboot boot recovery.img"
Once into the recovery, you can backup your current ROM, data, EFS and more.
Once you have installed TWRP, you are all set to install custom packages onto the device’s system. Alternatively, while on Linux or Mac OS, you can issue “./fastboot flash recovery recovery.img” command to flash the TWRP recovery.
Root
As you already have TWRP, simply flash the SuperSU file (version 2.56) to gain root access
@TheJesus @KAsp3rd, thanks guys for everything you've done over the past few days. no shade to @joe01gun but if people are going to use these instructions make sure you search the rest of the forum for what thejesus and kasp3rd put together to get us to this point - definitely appreciated. thanks @joe01gun for putting these additional instructions together.
Your post says the following:
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
yet, there's no link to the necessary files to "unzip" them. Any suggestions?
Thank you for the help, but where do we get fastboot set up on our PCs? Yes, this is getting confusing with the steps outlined above. I followed the first step and had to take out the battery because I was stuck in fastboot screen with small tiny text in the top left that didn't respond to any manipulation with the volume keys on the back of the device and wouldn't restart any way until I took out the battery.

Your condensed thread is more convoluted than the actual development thread which also includes the links to everything.
I'm still wondering why you have install Motorola USB drivers for an LG phone..
Understood
Understood
The one on development is straightforward and I managed to make it done.
If you don't lock the bootloader back, you will see bootloader unlocked when starting up.
If you have root enabled file explorer, you should remove /system/priv-app/adaptclient folder to avoid annoying root request from adapt.
Please use the main dev thread for instructions on what to do, found below. Having duplicates for what is essentially the same thing can cause confusion and just takes up unnecessary space. So I have closed the thread.

TWRP 3.0.2 for Acer Predator 8 ported by Ruben. - If you like my work please donate here, it will also give me a boost to make more things for this device : https://www.paypal.me/RubenCraveiro
----------- -----------
IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.
----------- -----------
New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk
2. Power off the tablet.
3. Enter fastboot mode by pressing the power button while holding down Vol -
4. Open up command prompt and navigate to the directory where fastboot.exe is located.
5. Pass the following commands:

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

I am making the following guide because root guides for the Xgody phones are pretty hard to come by, and documentation is sparse. Enjoy.
First, you will need to setup adb and fastboot on your pc. Download Minimal ADB and Fastboot here. If your PC doesn't find drivers for "adb interface", download MTK adb drivers here, and install it by updating the driver for adb interface in device manager.
Now you will need to boot up your phone, go to about phone -> build number -> tap seven times. Head back to settings home, go to dev options, and enable usb debugging, then connect phone to pc. Open minimal adb and fastboot, and verify that the phone is connected by running "adb devices" command. If you see unauthorized next to the phone's serial, then you need to allow access on your phone in the window that has popped up.
Next step is to unlock the bootloader, so that the phone boots with the Magisk patched boot image we will be flashing later on. In developer options, you will now need to check "oem unlocking". Now in adb, type "adb reboot bootloader". Screen should go black, and "fastboot mode" text should appear on screen. Quick Note - Only boot to fastboot using this method. Shutting down the phone by selecting power off in the power menu and then holding the key combo to get into fastboot will cause the oem unlocking switch to flip back to off, and the next step will fail. Thus, make sure to use the adb command to reboot to fastboot mode. Don't know why this is, but it seems to be some sort of lousy anti-unlock protection by the Chinese devs.
Now in fastboot mode, type "fastboot devices" on your PC. you should see the device serial and "fastboot" next to it. If you do not, check device manager again. If you see an unknown device such as "Android" you will need to again install the driver through device manager. However, this time select "bootloader interface", as you are installing for fastboot mode.
Once you see the device in fastboot, you can proceed to unlock the bootloader. Type "fastboot oem unlock". Check the phone, and accept the warning about unlocking bootloader. Now the command should finish and bootloader should be unlocked. Reboot to system with "fastboot reboot". You will see "erasing" as the phone resets, and then it will boot into Android.
Now you are ready to grab your boot.img. We will need to patch this file with Magisk to obtain root access. To obtain the boot.img, you will need to make a full backup of your phone's rom using SP Flash Tool. A detailed guide here is available to guide you through the process. You can grab the VCOM driver and sp flash tool at https://spflashtool.com/. To follow the above guide, you will need to know the cpu and flash memory type. If you didn't know already, the Xgody Y28 is running on an MT6580 and uses EMMC memory.
You can also obtain a copy of the stock rom here - https://mega.nz/#!6vB0gKSK!RJ9SZ3q-Zp33ZYMjTk42A7cgeubvq-W2C4G7Ln4y8Bo However, I recommend making a backup of your own stock rom instead, as that is the safest option. The rom here may differ slightly differ from your phone's and cause issues. Unlikely, but still a good idea to use your own backup.
Either way, you now have a backup of the Y28's stock rom. We now need the boot.img. Connect your phone to your pc, and on the phone, select media device (MTP). This will allow you to copy files to the phone from your pc. Find your boot.img, and copy it to your phone. It doesn't matter where, just put it in an easy to reach location in your internal storage. Next, you will also need to copy over the Magisk Manager apk to your phone. Download it here. Click on "Latest Magisk Manager". Save the apk, and then copy it to your phone as well.
Next on your phone, open your file manager. Find the Magisk Manager apk, and install it. Note that the next part requires you have an internet connection, as Magisk Manager needs to connect to github to download the magisk zip to patch your boot.img with.
Now open the Magisk Manager you just installed. hit install, and select patch. Find your boot.img and select it. After the process is complete, exit Magisk Manager, and find the magisk-patched.img on your phone that magisk created.
Connect your phone to pc again, and copy the patched boot image to your pc. On your PC, navigate to the folder containing your stock rom, and rename boot.img to boot-original.img. Now, copy the magisk-patched.img to the stock rom folder. Rename magisk-patched.img to boot.img.
Next you will need SP Flash Tool. open it up, and select the android-mt6580-scatter.txt in the scatter-loading file. A list of flashable partitions will load once the scatter file is processed. Uncheck all except the boot.img (as this is the only one we want flashed) Now hit download, and connect your phone to your pc. Make sure the phone is turned off, and the battery is removed before connecting to PC. The SP Flash Tool will then flash the boot.img to the phone. Once complete, you can close the program, and unplug your phone.
Boot your phone back up, and open up Magisk Manager. It should now say Magisk is installed.
Congratulations! If you have successfully followed the steps above, you now have a rooted phone.
