I've been trying for the last couple of days to root my MM G4 H815 v20e but all the guides I've tried to follow have either wanted TWRP installed before rooting, or root being required before installing TWRP. No matter which TWRP I tried, none would install. Yeah, the install would succeed ok, but when I tried rebooting into recovery all I got was the dead robot. Then I came across a method for running TWRP as a boot img and installing root from there. And it worked 100%, first time. So I'm putting this method on here so anyone else having the same problems as I had, can root their phone.
This is non-destructive but, as usual, I take no responsibility for you wandering from the path and breaking something. You will need an unlocked bootloader, instructions here, and your warranty will most definitely be invalidated after this. The original instructions were in Turkish, so many thanks to the original poster, and to Google Translate for at least making it understandable.
So I take it we're all sure what we're doing with adb, fastboot etc? This is serious stuff so if you don't think you're up to it, don't try it until you are. I'm just posting the method for rooting, the other stuff can be easily found. Plus it helps you understand the system of searching.
So when you're ready, connect your phone to your pc by USB cable, ensure USB Debugging is enabled, and off we go:
Step 1 - Visit https://dl.twrp.me/h815/ and download twrp-3.0.2-0-h815.img to your sdk/platform-tools folder. Rename it to "twrp.img". Copy this file to either the root of your internal memory or external sd card.
Step 2 - download SU zip from here https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip and rename it to "su.zip". Copy it to either the root of your phone's internal memory or sd card
Step 3 - switch to your sdk/platform-tools folder, shift and right-click on a white space and select "Open command window here"
Step 4 - type "adb reboot bootloader" [ENTER] then type "fastboot boot twrp.img" [ENTER]
TWRP will now run in memory
Step 5 - As TWRP isn't actually installed, you'll need to swipe the switch at the bottom to allow it to modify your phone
Step 6 - Tap Install and select su.zip. Select "Zip signature verification".
Step 7 - Swipe the switch at the bottom to flash the zip.
Step 8 - It would be a good idea at this point to also flash the TWRP. go back to the install screen. As it is an img file and not a zip you want to flash, tap the "Install Image" button at the bottom right, choose the twrp.img file you copied to the phone, and swipe to flash.
When complete, tap the Reboot button, choose Recovery and your phone should now boot into TWRP. Now choose to reboot to System and allow your phone to restart (it may take a while longer than normal and may reboot , mine did once).
And that's your phone rooted. Install Root Checker from the Play Store and run it to confirm your phone has been rooted.
Unlocked bootloader, I guess, yes?

Without unlocking the bootloader he wouldn't be even able to boot the twrp img, since its unsigned by LG!
This is common sense
If I unlock the bootloader I´ll also fire up the twrp (not boot but simply flash twrp)
Root is just optional there
U rock man!!!
100% working!!!! i've been looking for this for so long and all tutorials were complicated and hard to follow and you came with this simple tutotial xD i have the same lg g4 h815 20e. You are the real MVP!!!:highfive:
But why? Why wouldn't you just install TWRP seeing as you've unlocked the bootloader, might as well make your life easier in the long run...
adb reboot bootloader
fastboot boot twrp.img
copy twrp.img to internal storage
in twrp -> install -> images -> twrp.img -> select recovery and swipe to install
Can't install TWRP via fastboot (fastboot flash recovery twrp.img doesn't work properly, have to flash the twrp.img inside TWRP itself).

Since you have unlocked bootloader anything will work
you can simply boot the twrp (like the op shows) and flash supersu
or rather -> copy twrp img to the internal, boot twrp (look op) and flash the twrp img (tap first the zip/img checkbox) --it will ask where to flash -> select recovery, don´t tap boot...
Then you might also flash the supersu
and now you have twrp and root

The problem with the boot loop is only in the devices that are bootloader unlocked ? My H815 (506) is locked...and i was thinking at unlock the bootloader, but, i am "afraid" of the boot loop.
No, it's random

can i use this method for v20d? thx.
After typing "adb reboot bootloader" phone restarts to bootloader. And thats it. Typing "fastboot boot twrp.img" does nothing but writes <...> is not recognized as and internal or external command, operable program or batch file. Whats going on? Also if i type adb devices there is empty list of devices attached

You don't have fastboot installed, or you're typing the command wrong.
c:> adb reboot bootloader
c:> fastboot boot twrp.img
What happens if I want to go back to stock, will the device remain as it was before rooting and will receive OTAs and allow device encryption and all?
Was supposed to flash CM13 Rom. I did a full wipe including system via TWRP.
Before flashing I decided to reboot into recovery, but it didn't. Only gets stuck in the MI logo now. Can't boot into recovery anymore.
I can go into Fastboot mode. Tried flashing twrp via ADB but whenever i type 'adb devices' in command prompt it says device is offline.
Tried to enter EDL via ADB in fastboot mode, it gets stuck at 'waiting for device'.
When plugged in PC, it gets detected as USB ADB interface
Bootloader was unlocked prior, was on xioami.eu ROM before this. I have TWRP system backup of last ROM installed.
Hoping someone can point me in the right direction on what to do next. Very much appreciated, thank you.
Hi Supdow,
I was facing with the same issue and I also thought I bricked my phone... No worries. To solve it is very easy, just unlock your bootloader again with Mi UnlockTool. Than you have access to your recovery again.
Good luck!

Was able to unlock bootloader again, but I still can't access recovery. I may have forgotten how to exactly do this since the last time I did it. What do i have to do after unlocking bootloader? I tried flashing TWRP via fastboot but it only gives me an error.
So you have a few options
1. Hold volume+ & - and power (if you have twrp)
2. Take fedosis twrp 3.1 and installer, put twrp 3.1 into extracted installer folder, then shift+right click on installer folder, open cmd, then type
fastboot flash recovery twrp_name.img
fastboot boot twrp_name.img (or do step 1)
3. Just flash dev/stable with miflash (recommendation: go into fastboot, then like step 2 go into cmd and type fastboot oem edl then flash mi rom)
Hope this helps

Files all courupted
With stock recovery you can't use adb sideload in windows 10.
If you're unlocked i would flash Codeworkx TWRP, download the OOS 5.0.1 Full Rom Zip, boot into TWRP, copy the zip to your phone or sideload the zip.
If you're not unlocked (and thus being unable to flash twrp) use windows 7 and sideload the zip.
You can download ADB drivers here
Can you boot? Turn on USB debugging , make sure that you allow the device when booted.
Do an advanced devices when in the OS make sure it's there.
Then you can install a TWRP recovery and do what you need to.

Hi bro, I am unlocked ! I mange to find a win7 pc. I ran both commands “adb devices” and “Fastboot devices”
Both shows me my devices number hence drivers are working fine.
Now do I flash twrp and sidleload? Because I can’t sideload in stock “error: *cant read zip*”. Do advice me!
PS: can boot into OS, no OS in system only recovery . USB debugging was on before boot loop happens! Thanks for all advices !

be sure your bootloader is unlocked
turn your phone into fastboot
open command prompt to the folder your twrp is in.
rename the twrp image file to recovery.img
do the following command: fastboot flash recovery recovery.img
after that boot into recovery
press adb sideload
on the computer, open command prompt to the folder where your zip file is in.
rename the rom zip file to rom.zip
do the following command: adb sideload rom.zip
done!
Thanks bro, I shall update you on the situation once I done, at work now.
Do I need to “open command promt “ at my sdk folder/plat-form tools?

Cannot adb to the phone in FASTBOOT. adb devices shows nothing when in FASTBOOT, but shows the device when in normal boot.
Hence I cannot upgrade TWRP from 3.2.1-1 to 3.2.3-0. Was trying this so to upgrade from beta23 to the beta 26, now 27 with which 3.2.1-1 seems to have problems.
A 2nd approach, just re-installing beta23 without Magisk18 gives the stock recovery which manages the beta27 install. But then I'm blocked from a Magisk18 install and still cannot use FASTBOOT mode to put TWRP back on.
Thought the adb drives could be old and sought new drivers, even assuming your link is to the most current I don't know how to get my Windows7 to use the zip file. Can you assist? This would let me put the latest TWRP, hence install Magisk18 and be rooted again!
I've had my Essential two weeks i was on 8.1 beta.Today i unlocked the boot loader.Then installed twrp while in twrp i side loaded magisk.I went back to fastboot then hit start .The phone just went into a bootloop.I Was able to go back to twrp 2 times but now i can't get back to any type of recovery.I Can get back to fastboot mode ishow all the info and secure boot says yes and device state unlocked.My pc see essential phone fastboot in the device manager but i can't get adb to see it .Can anyone help me ?
forgot something
looks like i skipped this part . Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.Is there anything i can do?

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.
WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.
I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help
This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:

How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.
I need help! Here’s the story. Sorry for the lengthy post. TL;DR at the bottom..
- Was on B32, unlocked BL, TWRP installed, rooted with SuperSU
- Updated to B35, but lost TWRP and root (I don’t know how, but I assume I must have wiped the wrong things? - system? - I’m clearly a novice)
- Now I’m on B35 with an unlocked BL, but despite days of searching and researching, I can’t for the life of me figure out how to get TWRP reinstalled. I want to have TWRP before trying Magisk (have never used Magisk before, but would like to try it this time instead of SuperSU)
- From my Mac, using terminal, adb recognizes my devices.
- “adb reboot boot loader” gets me to a list of options “power off, restart, recovery, fastboot, back to previous page”. Choosing fastboot simply restarts the phone. What should “fastboot mode” look like?
- I tried flashing TWRP via adb while on this page and terminal stopped at “waiting for any device” and did nothing
My conclusion is that I need to downgrade to whatever latest version allows fastboot commands to work properly? Is this B15? If so, is the only available B15 zip the one that is on the ZTE website? Do I just wipe data/dalvick/cache and flash this zip?
Do I not need a Bootstock and Systemstock like @DrakenFX usually posts? That’s how I’m used to doing any updates.
Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

- Updated to B35, but lost TWRP and root (I don’t know how, but I assume I must have wiped the wrong things? - system? - I’m clearly a novice)
- Now I’m on B35 with an unlocked BL, but despite days of searching and researching, I can’t for the life of me figure out how to get TWRP reinstalled. I want to have TWRP before trying Magisk (have never used Magisk before, but would like to try it this time instead of SuperSU)
- From my Mac, using terminal, adb recognizes my devices.
- “adb reboot boot loader” gets me to a list of options “power off, restart, recovery, fastboot, back to previous page”. Choosing fastboot simply restarts the phone. What should “fastboot mode” look like?
- I tried flashing TWRP via adb while on this page and terminal stopped at “waiting for any device” and did nothing
My conclusion is that I need to downgrade to whatever latest version allows fastboot commands to work properly? Is this B15? If so, is the only available B15 zip the one that is on the ZTE website? Do I just wipe data/dalvick/cache and flash this zip?
Do I not need a Bootstock and Systemstock like @DrakenFX usually posts? That’s how I’m used to doing any updates.
Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

I'm not sure where you read all that BS, but if your bootloader is unlocked then you can install TWRP via EDL (Or fastboot if you have it). No need to downgrade for anything :laugh: in the past you would have needed to downgrade in order to unlock the bootloader, now it's not even needed
Download EDL Tool by djkuz and install TWRP with that one. Or you can use axon7tool by tennear, but it's much more finicky and ran entirely by commands (no UI).
And just to avoid more trouble, DO NOT LOCK THE BOOTLOADER! You do that with the system even barely modified and you brick the phone. A bunch of people tried to do something, got scared because they made a simple correctable mistake and just locked the bootloader thinking everything would get restored to stock - doesn't work that way.
Not saying you will do this, but I've seen about 4 or 5 people that started just like you and ended up doing that

Wow, thanks so much for responding to this. Sounds like this should be easy! A couple of questions before I go about following your advice:
1). Do I download EDL Tool to my computer or phone??
2). If I'm downloading it to my computer, does it matter that I'm using a mac?
Thanks again for your help!

Oh, skipped that part. EDL Tool is a .bat. I'm pretty sure you won't be able to run it on a Mac. If you can find a Windows PC somewhere to do this, it'd be much better...
But there's another way.
Issuing "adb reboot bootloader" effectively sends you into fastboot. That list you mentioned is fastboot (if it says "Start" in green, and you can scroll that, it is fastboot). Just use fastboot from the pc: Put TWRP on the fastboot folder on the PC, then issue "fastboot flash recovery twrp.img" with "twrp.img" being whatever the twrp file name is. After that issue "fastboot reboot recovery". And as soon as you are on TWRP, DON'T GET OUT OF IT. Just wipe data, system, caches; then flash a system (e.g. b10 bootstack and stocksystem), then also flash Magisk, and THEN boot to system

"adb reboot bootloader" takes me to the start up screen that says "your device software cannot be checked for corruption..." etc. and gives you 5 sec to either press up or down on volume keys to get to list: “power off, restart, recovery, fastboot, back to previous page”, but the list is all white. If I select "fastboot" it reboots the phone and starts that cycle over again at the "your device software cannot be checked for corruption..." etc page.
Nowhere am I given a chance to use fastboot commands. I'm never on the page with the green "Start".
..This all seemed a lot simpler on my Nexus 5..
Thanks for your help/patience.

I thought you had fastboot since you described the 5 seconds screen and both are very similar. It's normal not to have it though.
I think there's some version of axon7tool for Linux but I'm not sure at all. The best way would be to find a Windows computer.
I wonder how you actually installed TWRP the first time? Via fastboot?
As soon as you get TWRP you should be able to run a few commands to get fastboot back just to have it around.

I have adb and fastboot installed on my Mac and I can't remember how I got it working on my phone in the first place, but I've only ever used a Mac for all this. Terminal recognizes my device and responds to commands until I try "fastboot flash recovery twrp.img" then it says "<waiting for any device>" and does nothing.
Thanks again for the help. I'll keep hunting though. I don't have access to any Windows computer.
Cheers
