Root for Kit Kat 4.4 AT&T and T-mobile leaks

Ok after several tries many flashes I found a way that you can root you device. so here goes this tutorial.
after flashing KK AT&T or T-Mobile, once it rebooted manually keep holding dow volumen key to get into fastboot mode. In there you need to do the following.
download TWRP for KK from here http://androidhosting.org/Devs/Dhacker29/MotoX/
flash it using fastboot. "fastboot flash recovery twrp_name.img" without the cuotes where twrp_name is the file you downloaded.
once flashed access recovery and reboot from TWRP, it will ask if you want to root, click yes.
then follow the normal process of sign into your google account etc.
Note that you need to wipe all your data before installing any of the leaks. to do that using fastboot the command is fastboot -w
Note 2: after flashing you cant go into android setup. ypu need to press volumen down antil it goes to recovery.
Note3: I'm not responsable for any demage or bricked device.
hope this helps.
Regards
This is only for people who have an unlocked bootloader. It will not help those who are running the AT&T phones and flashing the system.img and boot.img
This method is no different than what is already known for unlocked bootloaders.

I will not argue the point with you. Your method you listed here is no different than that of the standard method to install a recovery and root on a phone that has an unlocked bootloader.

Help Z00T stuck on bootloop

Help im stuck on bootloop i can get into fastboot and recovery but recovery automatically reboots. I read that there are other .img you need to fix it but i cant find any of them only boot.img.
Is there anything i can do or is it completely ****ed.
its unlocked not rooted bricked while trying. tried sideloading, tried running
fastboot erase cache
fastboot erase userdata
fastboot erase system
whould writing it to an sd card work?
Still can't access fastboot while holding volume up + power button?
I can get into fastboot fine but after 1 min or so it reboots
Since you have unlocked BL flash latest twrp fast. Rename it something short so it will be easy to type
Okay i did that it got into the opening screen for twrp then it rebooted automatically.
FIXED: okay i tried again and it sdidnt reboot what would i do next?
nice that you can now reboot to recovery, all you have to do is flash a custom ROM and gapps. Were you on stock LL or MM ROM before you bootloop? Sorry with the late reply, Im busy with work. Quote my reply so I can receive notification.

I was on stock MM (Marshmellow). Thank you, you've been so much help.
You can flash CM13/14 base ROM without a problem since you were on stock MM. If you decided to wipe system in TWRP, manually power off first in TWRP, wait for the phone to turned off then reboot back to TWRP and flash your new ROM and GAPPS. Do not reboot to system if you wipe system cause you might lose your recovery.
Edit: I only do this when I also wipe Internal Storage.

Hard/soft brick

I think I messed up my PH-1 something royally.
All I was trying to do is unlock my bootloader and load Magisk.
To preface this, my PH-1 seemed to act a little wonky from the get-go. I bought it 3rd person from a guy on craigslist so anything warranty involved I think I'm out of luck.
The phone would take a while to power on, it took something like 10secs on the power button just to turn it on. And if I set it to reboot , it boots into the bootloader. Also, I was never able to access the recovery (even using power + up). It always felt like I had to hold the buttons for way to long to get to its destination; e.g. up and power to get into fastboot.
Ok where I'm at now. In can occasionally get into fastboot mostly after it bootlooping a few times. It won't get past the Essential logo if I try to boot it up.
PS I was able to unlock the bootloader.
Steps I took to remedy this:
> erase all user data in fastboot
> hold power + u + d to hard power off
> follow this guide https://forum.xda-developers.com/essential-phone/how-to/guide-rooting-essential-ph-1-magisk-t3701976
> attempt to install stock system image via flash-all
>a ton other
Here are the results of that.

That's the exact process I was going through, and it finally booted up.
The issue I was having was a bad usb connection which wouldn't allow me to unlock_critical.
SOLVED. Still no Magisk, we'll worry about that another time. 5hrs of troubleshooting is enough for one night.

SO close to getting Magisk to install, any reason the refuses to flash the boot partition? I used the stock boot.img and had Magisk patch it before I flashed

You have to flash magisk in twrp recovery NOT bootloader mode.
It's right in the OP from the rooting guide you followed:
Do not set up a password if you are on 8.1 twrp doesn't work.
You need to read through that rooting guide and make sure you know what you're doing before you try.
This phone is easy to hard brick and there is no solution to recover from that.
OREO 8.0/8.1
REQUIREMENTS:
An unlocked bootloader.
A working ADB/Fastboot environment on your computer. Knowledge on how ADB and Fastboot works is also preferred.
The stock boot image for whatever build you're running/trying to root.
The latest TWRP build for our device.
If on 8.1, remove your pin/pattern/passcode until the root process is done.
1. Download both the stock boot image for whatever build you're running and the Magisk or SuperSU zip. Transfer both files to your device's internal storage.
2. Reboot your phone into the bootloader, then open up your command prompt or terminal and flash the latest TWRP build for the device using:
Code:
fastboot flash boot twrp.img
3. Once TWRP has finished flashing, reboot into your recovery. When prompted, enter your pattern/passcode/password to decrypt your data in order to gain access to your internal storage.
4. Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.
5. Whenever Magisk/SuperSU finishes installing, simply reboot your device! You should now be rooted.
*NOTE: TWRP will NOT remain installed on your device.

I realize all that, the issue is I cannot access any sort of recovery because I think my bootloader is defective.
For example from a cold restart if I press the power button for say 3 -5 seconds it wont boot, just boot to the Essential logo and loop. To get the phone to boot I have to hold the power down for 15-20 seconds while it bootloops a couple times then it'll boot.
Is there a possible way to reflash the bootloader software if it is defective? It's unlocked btw
There is a way to install magisk via fastboot with a patched_boot img which I'm working on. Cant seem to find the right boot img to patch for 8.1
PS Is it possible to flash .zips through fastboot? e.g. custom roms etc
Was finally able to get into recovery, so all is well. Thanks for the help yall
OP, what was your process to successfully get into recovery and fix your problems?
It may help others sometime?

It's really hard to say, my phone has a serious problem with it. sometimes I cant get it to boot, it will boot into the bootloader over and over and over. I've managed to get Lineage 15.1 on if for a bit until I tried to get back into the recovery which sent it manic.
I just got lucky I was able to get into TWRP and flash lineage.
my first issue not being able to flash the stock image via fastboot because I didn't unlock_critical which can sometimes fail when the usb connection is bad.
Currently flashing stock again if my phone will boot up. I'm not sure whats wrong with my bootloader but its causing a ton of havoc

Same boat for me - just keep rebooting to show Powered by Android Screen and then reboot again and again. Was able to see my device using fastboot devices command but all attempts to access recory just repeat the bootloop entry. I would happily check the OEM UNLOCK option in dev settings but can't even get it to book to any OS to make that option happen. Still shows bootloader locked on bootloader screen - any help someone can suggest?
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.

I am in the same boat. I tried to re-install the OS, but because my USB debugging was not enabled, Fastboot worked but ADB would not and since I basically wiped the recovery area, my phone will only boot into Fastboot but will not allow any loading of recovery. I would pay for someone to help. This is so hard to figure out. I have contacted Essential but since my phone is over 12 months old, the warranty has expired.
Help please. It seems like such a waste to have a bricked phone.

Help Please! - Mate 9 Softbrick

Hi All,
I flashed oreo to my Mate 9 today, all was well until I tried to root.
Now it won't boot, stuck in bootloop. I can get to Fastboot and TWRP Recovery.
Tried to reflash, but now no bootloop - just got fastboot and TWRP.
When in TWRP device is not showing up in ADB devices, so can't push anything.
Any ideas as to how to come back from this?
Thanks.
Things are worse now... it won't reboot to recovery. Can still get fastboot though.
When reboot to recovery it just sits on "your device is booting now..." and doesn't seem to progress. I have re-flashed TWRP via fastboot... but still the same.

Device shows phone and FRP as unlocked.
I have extracted the oreo update using a Perl script i found on another thread. Flashing system, kernel, recovery_ramdisk has made no difference.
Anyone able to help please?
What root did u use magisk or su?
Why don't you use this method?
Its safe and no more side effects.
Then after you can root with magisk.

I think i really messed up

So here is what happened. I decided to take a crack at twrp and rooting my essential phone. its fully updated to aprils patch
unlocked my bootloader. HOWEVER i never used the command fastboot flashing unlock_critical. how ever it still said my boot loaders unlocked.
installed twrp no issue (other then touch but i figured that out) installed elementalx kernal. made a backup in twrp just in case.
booted into android fine no problems. found out my wifi does not work. ok now im just giving up. found out flashing the boot img will fix it. well i flashed it via twrp and when it asked where i said to the boot.
now my phone boot loops. i cant get into twrp. only a default recovery mode for android. i can get into the boot loader but im scared because ADB cant find my device anymore. trying to wipe deivce makes it reboot and boot loop again.
am i screwed? i dont care about the data but its 3am and i think i really messed up my phone

Are you still bootloader unlocked?? Can flash files via fastboot? If you can run the command "fastboot flashing unlock_critical" and then flash bts from this thread https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
