Do you have read and followed the official twrp thread? You will not install a recovery by adb but with fastboot instead.
Check my twrp thread for the how-to.

Root Canvas A1 without unlock or custom recovery [Tutorial]

I'm not sure if someone has posted this before. But every root tutorial I see for canvas a1 and other android one devices says that you have to install custom recovery. This is useless and risky considering how android one is like nexus, with infinite freedom.
Here's how to root Micromax Canvas A1 (and probably other android one devices too, I have only this one) without even unlocking your bootloader. You'll need adb, and fastboot binaries.
First download any of these recoveries by @varun.chitre15 : https://www.androidfilehost.com/?w=files&flid=19345 (that's your recovery.img)
Then download the SuperSU script from http://forum.xda-developers.com/showthread.php?t=1538053 (that's your UPDATE-SuperSU-*.zip)
Then in terminal (or command prompt)
Code:
adb reboot bootloader
fastboot boot recovery.img
The recovery you downloaded will boot. On the phone, choose install zip -> install zip from sideload. Then come back to terminal and
Code:
adb sideload UPDATE-SuperSU-v2.14.zip #or whatever it is named
Your phone must now get rooted without you changing anything dangerous. At least it did on my canvas a1. And I'm waiting for the Lollipop update now. Meanwhile you might have to install xposed framework.
not very clear
Hello i am just a beginner i want to know how to install fastboot and adm and if you can make a video thanks in advance
Yes, It can be done in this way, but in my opinion it would be more risky..
In case you bricked your device(Flash wrong kernal or incorrect rom) or its not booting up and you have a unlocked boot-loader. You would not be able to flash stock rom from SP tools. with unlocked boot-loader / preloader SP tool would not detect your device.
But i cant see any terminal in my boot up

marshmallow twrp and root help

just installed 6.0 on my lg g3 d855 32gb
trying to root and install a custom recovery but not able to. used the method with kingroot then installing supersu from twrp but then when booted supersu keeps asking to update binary and then freezes. am using the v30b-global-com version
any straight forward way to do it? without kingroot
i dunno if that's weird, but i can't even enter the fastboot to install the recovery using fastboot command

1) Fastboot doesnt work on LG G3 because it bootloader isnt natively unlocked
2) Please do not install TWRP on your current firmware. You will brick your phone
If you need TWRP you must downgrade to KitKat before you can install it.
I did install twrp and it booted normally. Using kingroot and a method i found on the forum. But the problem was with supersu that it kept asking to update binary which never happened. Anyways thanks for the reply. Phone not with me anymore

Need help unlocking bootloader also can't enter recovery mode.

So I've installed TWRP recovery before unlocking the bootloader and now I can't unlock the bootloader and also I can't enter recovery mode.
I have been 2 hours trying to unlock the bootloader without success.
Current status:
un-rooted phone. Tried using the asus official bootloader unlocker app both rooted and unrooted without success. Also tried the ADB method.
I think I have the TWRP recovery installed - not sure. fastboot status says bootloader version is "unknown". Twrp manager says custom recovery not installed or not detected.
Unlocking bootloader via ADB always send "FAILED remote: permission denied".
Also I can't enter recovery mode. In fastboot i choose "RECOVERY" in red and it just restarts the phone to fastboot mode.
Asus version 2.20.40.160_20151225
Thank you very much!!
edit: Managed to unlock bootloader with one click unlock v2! will proceed to install twrp
Have you tried flashing stock recovery through bootloader, you can't flash regular twrp before unlocking bootloader, if you can successfully flash the recovery then you can adb sideload the full Rom and that should fix any problems, you could also flash through bootloader, after you have a clean flash, root the phone and use wondrous to unlock bootloader and flash twrp, should fix any problems you are having

Root H815 on MM 6.0 V20d?

Hi guys ☺,
I bought today G4 eu model,it came with Marshmallow 6.0 V20d version.
I want to root it because of Greenify and Xposed,to increase the battery time,maybe later to flash some rom but...
There is a lot of topics on this subject,I started to read but I'm lost right now...as far as I saw,I can't root Marshmallow without unlocking the bootloader,only Lollipop,right?
Is it a big trouble to go back from MM to LP?
I'm not new in this flashing and rooting stuff,I had (still have) a Motorola Razr XT910,I flashed it 100 times for sure for 3.5 years but I didn't had to unlock the bootloader (it's impossible anyway) and there's a custom recovery Safestrap,modified Twrp which allows to flash and use 6 different roms,from JB to MM,without changing the kernel...
I will be grateful if someone can point me in the right direction,to give me some useful links etc.
And is there some list which procesess are safe to freeze with TB and which ones I can greenify?
Oh,and the bloatware too...
Sorry if I'm demanding but I want to bring out the best from this phone
Thank you in advance

Hi,
root without unlocking bootloader works only on lollipop, right. Not sure if u can downgrade, but when, u will use "LGUP" tool with the "H81510D.kdz" file. Maybe there exists a pre-rooted kdz to flash.
If u want to root android 6, u need a unlocked bootloader. Rooted Android 5.1.1 or unlock bootloader with rooted android 6.x.x
Ok,I successfully unlocked the bootloader but now I'm stuck with rooting and installing Twrp...
I've downloaded BETA-SuperSU-v2.67-20160121175247 and TWRP-3.0.0.0-H815+ but there's a lot of metods,which one should I use?
Flash SuperSu+Twrp with stock recovery?
Install Twrp with adb command and then flash SuperSu with Twrp?
Install both with adb command?
I also saw somewhere that I must flash some other kernel that is already rooted...
I just need root and the Xposed for now,help me guys!
Im also Confused..Where can i find rooted kernel?
I already did this Method u said...But I got Boot Loop
Then I revover my phone with Lg Bridge
We need to find this.....I also Had Android MM with V20d

In my case I wasn't able to flash recovery on the stock kernel, I had to flash boot.img unpacked from the custom kernel like SimpleGX and only then I was able to flash recovery and full kernel through it.

the method i followed was-
1. boot into twrp recovery with adb command(you need to have the twrp.img file in PC and also copy it in internal memory of your phone with SU)
2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

I didn't know i could flash something other than .zip files with twrp.
As for viper4android i tried normal way, flashed it with twrp, flashed extreme music mod with v4a fix. None seem to work. The drivers never get installed.
Xposed i haven't tried. I was in process of getting more information about it by reading various threads. But all seem to point to problems like bootloop, fc and Bluetooth issues. Can you guide me towards the best version of xposed for v20d with way to avoid problems or with as less problems as possible?

Here is the official Xposed thread
http://forum.xda-developers.com/showthread.php?t=3034811
Download xposed-v80-sdk23-arm64.zip and flash it with Twrp.
Download XposedInstaller_3.0_alpha4.apk and install it.
And just in case if you have a bootloop,download xposed-uninstaller-20150831-arm64.zip.
I haven't had any problems
Oh,be careful which Xposed module you install.Here is the thread of working/not working modules

Flash Imperium Kernel or SimpleGX Kernel. I used their kernels and ROMS on my older phones, they are legend. I suggest you to flash Imperium Rom. It includes kernel and everything and it is updated regularly by its dev.
This is kernel thread: http://forum.xda-developers.com/g4/orig-development/kernel-imperium-kernel-g4-v1-0-t3282915

I think doesn't need to install recovery to root the phone.
Just this:
1) adb reboot bootloader
2) fastboot boot TWRP-2-8.7.0-h815.img
Wait a second and it will open, on the phone, the recovery.
Once open go to Advanced -> ADB sideload and take a swipe to start it where it says "Swipe to Start sideload".
Now on the PC write
3) adb sideload BETA-SuperSU-v2.67-20160121175247.zip
( If it says after the instalation to install supersu etc just abort it)
And then, when installation is complete, press "Reboot System"
I rooted it this way, without install TWRP Recovery

Yeah - but the question has to be asked - why unlock the bootloader and root and not install TWRP? If you've got as far as unlocking the bootloader you might as well make life easier for yourself and install TWRP - that way anything you want to flash in the future can be done without being tethered to the PC, and also allows you to take proper full system image backups etc.

Of course , i agree with you. By the way, we can't root g4 on m6 without unlocked bootloader.
And finally, i decided to pass twrp on my phone, for every file i want to install from twrp, and not every time to boot from pc
You're right
p.s. the first thing i did after twrp installed, was to install g5 live wallpapers

[RECOVERY]Honor 7x stuck in bootloop

Hello everybody, my Honor 7x BND-L21 entered in a bootloop (i haven't flashed custom rom or anything else).
I'd like to solve this problem without loosing my data.
Is there any way to unbrick the phone without loosing data?
Or is it possible to flash a custom recovery (TWRP), make a full back-up, and after that unbrick the phone?
My phone isn't rooted and the bootloader isn't unlocked.
Thanks

To touch on the custom recovery idea... To install a custom recovery, you would need an unlocked BL. Even if your device was still able to do the BL unlock command (they locked that down a long time ago, but some have been able to downgrade to a version that allows it still), it wipes the device on BL unlock. Since you are looped, you can't get into ADB to use pull commands for example. I think you are out of luck regarding not loosing data.

OK thanks for your answer. And what about flashing the stock rom of the device through the standard procedure (I saw that I should copy the rom in a folder named dload, press simultaneously volume + and -, and it will flash the rom, am I right?). Is this going to erase all data too?
Moreover, I was trying to connect the phone to the laptot through ADB but I can't see the device when I send the command <adb devices>. Can I solve this or this was what you were talking about here: "you can't get into ADB to use pull commands for example" ?

ADB only works with a booted ROM, so yeah that was what I was talking about. I'm not sure about that method of flashing stock. I've only seen the update procedure through system and not manually.
