Remove ClockworkMod Recovery and relock after bricked

So I tried to update to KitKat 4.4 and was never able to get passed the loading screen. I booted into ClockworkMod Recovery and wiped everything and now the device will not go passed the Google loading screen. The device is no longer recognized when I plug into the computer and I cannot access through Wugs.
I called Google and they are sending out an RMA for this device (I did not tell them it was unlocked) and they are sending out a replacement.
Is there anyway that I can remove ClockworkMod Recovery and re-lock this device without being able to access the device through a computer?

Whoa, RMA's should be only used for last resort bootloader bricks! Since you still have the bootloader ("Google" logo at startup), hold Power + Volume Down to enter Fastboot mode and try reflashing the factory images. Just to be safer, use the Universal Naked Drivers and skip with bootloader image. Don't forget to have the ADB and Fastboot binaries in the same folder. I wouldn't recommend toolkits as they don't expose new users with these situations.
If you need anything else, let me know. If I completely missed on what you needed, sorry about that.
Also, just as long as the bootloader update isn't interrupted or type "fastboot erase bootloader" you should be fine without an RMA.

thanks for the reply.
I am able to boot in recovery mode on the device and this is recognized by Wugs as "ADB - device on". When I attempt any flash, it checks Fastboot status and I receive notification that the "Fastboot device was not found". I cannot find a compatible driver when I am in fastboot mode running on a Windows 7 x64 machine.
Any idea on how I can get this N7 to function, return to stock, or at least remove ClockworkMod and lock the bootloader so I can RMA?

Unlocking problems? Boot loop? Help please!

I rooted my oneplus 2 some time ago to install the Screencast.app that there was on the oneplus one. I then after a while noticed that it started to perform worse than before i rooted it, so i decided to try to unroot it to fix the performance. But when i rebooted to fastboot and tried to flash the stock recovery, it said that the bootloader was locked. I then tried doing the unlock command (fastboot oem unlock), and it seemed to work (although - it didnt - in cmd it said finish but when i booted into bootloader again it was still locked) but when my phone tried to reboot, there was i quick flash of the oneplus logo and then the screen went blank. When i tried turning it off, i just rebooted and did the same thing. I could not boot into recovery either. The only thing i could do was booting into fastboot and from there i managed to use the command fastboot continue and restart my phone properly. So now i cant use my recovery to factory reset, i cant install a new recovery because the bootloader is locked, and now every time my phones powers off, i have to do the same thing with booting into fastboot and do the fastboot continue command to start it.
Can anyone tell me what the issues is here and how i can solve it?

I have the same problem, but once I got the phone to boot, I did a factory reset. Now I'm unable to even boot, literally the only thing that works is fastboot.

If you can get into bootloader mode then maybe try fastest flashing things like stock recovery. If you manage to get stock recovery then boot into it and adb sideload a stock OTA from Google Developer website. Other than that I'm not too sure, you might need to contact Google/Huawei if that or anything else doesn't work.
---------- Post added at 08:43 PM ---------- Previous post was at 08:35 PM ----------
Okay, in bootloader mode try flashing the stock bootloader image from their OTA by typing fastboot flash bootloader (drag bootloader image here) then type fastboot reboot-bootloader. After that type fastboot flash radio (drag radio image here). Then type fastboot reboot-bootloader again. After that you can try booting up. If you are somehow able to get into recovery mode whether you can boot up normally or not then you can simply adb sideloading the stock OTA. If nothing I have said gets you into recovery or to boot up the device then you are probably screwed to be honest. Good luck

Hi,
thanks for your reply,
let me make sure, that i understood you clearly,
when i boot into bootloader, and select the recovery mode,
it get rebooted, shows Google “in white” then restart again, and again in same loop exactly as if i booted normally, not into the bootloader
as i read in other posts, i should expect the device to show me a confirmation message, or something similar,
but in my case, nothing at all, restart, and keep restarting
The options i have with bootloader are
1- Start
2- Reboot bootloader
3- Recovery mode
4- Power off
5- Barcodes

In bootloader mode, not recovery try flashing the bootloader and radio like I said.

Hi... RMA your phone... Contact google or Huawei depending where you bought your N6P.
Check this link. A lot of people seem to be in the same situation at the moment:
https://forum.xda-developers.com/nexus-6p/help/boot-loop-death-nexus-6p-t3533528

You're in the same boat as a few of us.
Phone is stuck in a bootloop, won't go to recovery. Only boots to fastboot, but your bootloader is locked so you cannot boot/flash any zips, even official ones. That means no recovery access, which means no adb commands. ADB commands *might* be useful to reboot into EDL mode for QFIL flashing, or for wiping partitions. Problem is - if that bootloader wasn't unlocked, it's not going to be. You need to check "Allow OEM unlocking" in settings BEFORE the phone dies, otherwise you will not be able to unlock the bootloader and thereby reflash the phone.
In a perfect world - we could use EDL mode (or something) to use QFIL/MiFlash to completely rewrite the partitions and MAYBE bring the phone back to life, but the stock bootloader does not allow access to EDL. (tried the custom fastboot.exe meant to send the reboot-edl command, didn't work). If someone can figure out the JTAG pins, we might be able to move forward by purposely bricking it to QHUSB_BULK mode.
The thing is - we don't know why the phones started bootlooping in the first place. For some people, a simple cache wipe/factory reset fixes the loop and away they go. HOWEVER, those of us stuck in fastboot mode with a locked bootloader have no way to erase/wipe/format/write partitions, and even if we could, there's no guarantee it was a software issue that caused the loop in the first place.
TL/DR - You have a locked bootloader and cannot access recovery mode, this means you won't be able to flash/wipe/format partitions or images. Best bet is to contact Huawei/Google, but you'll need the original receipt. If that's not an option for you, you're gonna have to wait until the XDA geniuses out there grant us some answers.

I'm stuck with a black screen and QFIL and XiaoMiFlash won't work. My bootloader is unlocked but I can't get to fastboot. Screen is always black but Quallcomm HS-USB QDLoader 9008 appears in device manager. No red light or vibration when connecting the phone.

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.

This is also very helpful
https://mata.readthedocs.io/en/latest/

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.

US996USA lost root and TWRP - No fastboot

My V20 was unlocked via factory method and rooted in2017. I had xPosed framework installed. One morning in Dec. 2020 I woke to an unrooted phone. I tried to install my latest TWRP backup but TWRP was gone. The hardware button combo that always got me TWRP did a factory reset instead. Now I cannot get fastboot. Both ways of entering fastboot produce a regular boot. The bootloader unlocked nag screen still appears on boot up. I don't know what happened but I want root back. What can I do?

I am not XDA lingo savvy so forgive me if my answer does not apply.
I recently tried roting US996 with Magisk vs 21.4 but got a loop start up.
I then noticed Fastboot would not find the device.
However if I hold vol up and plug in the USB cable to the computer it will go into fastboot. I can type Fastboot devices and it will show my device. That was how I was able to start the process to restore the phone to stock.
If that helps great, if not , sorry I am just trying to give back something as I try to get this to root in Magisk 22. (still learning)
