hi all, i have tried to return to stock rom from cm 13 following the instruction from the nvida site. I rebooted the shield in fastboot, my device is already unlocked, but when i write the command flash-all.bat in the minimal adb and fastboot for flashing recovery.img system.img .... the program says "error: cannot load recovery.img" and it asks me to exit.
Solutions?

You have to explicitly state the location. Ie:
Fastboot flash recovery c:\locationoffile\twrp.img

It is working! thanksss!!
I am having issues booting into my unofficial TWRP installation on my Moto g stylus 5g after attempting to install an unofficial modded LineageOS image.
My problem: I try to boot into TWRP through the command line on my computer using
Code:
fastboot boot twrp-boot.img
, but my new phone disconnects from my computer before the command can finish. Though TWRP is already installed and I can access it by entering recovery mode without my phone needing to be connected to my computer, the touchscreen on the installation does not work. The touchscreen only works if I use the
Code:
fastboot boot twrp-boot.img
command.
My drivers are the latest version: 33.0.3.
I unlocked the bootloader. To do this, I:
Tapped on the build number to become a developer.
Enabled OEM unlocking and USB debugging.
Unlocked my bootloader.
I installed TWRP recovery. To to this, I:
Downloaded the unofficial TWRP image linked in the first paragraph, as well as the Magisk ZIP.
Ran
Code:
fastboot boot twrp-boot.img
while in bootloader.
Copied the image and the Magisk ZIP from my computer to my phone.
Installed TWRP using "Install Recovery Ramdisk".
Installed Magisk.
I attempted to install LineageOS. To do this, I:
Downloaded OTA ZIP, copy partitions ZIP, and boot image from the LineageOS thread linked in the first paragraph.
Flash booted the boot image.
Selected ADB Sideload mode in Lineage recovery.
Ran
Code:
adb sideload copy-partitions-20210323_1922.zip
and
Code:
adb sideload LineageOS-Modded-19.1-Osaka-V2-OTA.zip
on my computer.
I attempted to re-access TWRP recovery, after Lineage recovery seemed to replace it. To do this, I:
Ran
Code:
fastboot boot twrp-boot.img
while in bootloader.
Installed TWRP using a different method than the previous installation (maybe "Install using this image") because I couldn't copy the installation files to my phone as my phone was no longer writable.
After I rebooted I could no longer use the touchscreen to navigate TWRP. That is, until I figured out
Code:
fastboot boot twrp-boot.img
worked. But after I attempted to enter ADB Sideload mode using TWRP and install one of the ZIP files I needed to install for LineageOS (
Code:
copy-partitions-20210323_1922.zip
), my phone began periodically turning black and disconnecting from my computer, again.
It had been turning black, disconnecting, then turning back on and reconnecting on a regular interval while I was trying to unlock the bootloader. I almost made a post about it. When I tried one more time, just to get the error message I could copy and paste, the command I had been trying to run ran fast enough and it worked. What I had done differently that time was I ran the command right away, without running
Code:
fastboot devices
.
After a while the phone stopped disconnecting periodically. After I installed one ZIP, it started again.
How can I get my phone to stop periodically disconnecting from my computer? How can I access TWRP again?

First of all, the command that you tried to use is not even the correct command for fastboot booting TWRP(unless your TWRP file is named "twrp-boot.img" and if the file is stored in your fastboot folder on PC). The correct command is:
fastboot boot twrp.img
The command you typed isn't even an actual command, that I know of. The command you typed is trying to tell fastboot to tell TWRP to boot a boot.img, which, makes no sense at all and isn't how it is done.
There is:
fastboot boot twrp.img
And
fastboot boot boot.img
As far as I know, there is no such thing as:
fastboot boot twrp-boot.img
The way fastboot commands typically work is:
fastboot <what you want fastboot to do> <what you want it to do it to>
In your case, you want to use fastboot command, so, you type: fastboot
You want it to boot a .img, so, you follow that with: boot
You want it to boot a twrp.img, so, you follow that with: twrp.img
If you put that all together in one command, you get:
fastboot boot twrp.img
This command is typically used to boot(not flash) a live TWRP session on devices that have locked bootloader because they can't actually flash TWRP "onto" their device with a locked bootloader. This command would probably actually boot your twrp.img if it is stored in your fastboot folder on PC and if the file is actually named "twrp.img"(you can rename it to "twrp.img" if it isn't). But, it wouldn't be booting the TWRP that is installed in the recovery partition on your device, it would be booting a live TWRP directly from the TWRP file in your fastboot folder. In other words, it boots on your device "from" your PC "onto" the device without flashing it, instead of booting on your device from the recovery partition on your device.
If you wanted to flash the twrp.img, the command would be:
fastboot flash recovery twrp.img
Fastboot followed by what you want fastboot to do(flash recovery) followed by what you want it to do it to(twrp.img).
But, all of that is beside the point because you say you already have TWRP installed. If you already have TWRP installed on your device, you don't need to use the "fastboot boot twrp.img" command line. You should be using adb, with this adb command:
adb reboot recovery
This adb command that I posted is used to boot into TWRP on devices that already have it installed. It is also used to boot into stock recovery if stock recovery installed. In other words, it boots yo whatever recovery you have.
Hopefully, you understood all of that without my wording confusing you.

Hello. Thank you for responding. "twrp-boot.img" is just the name of the file on my computer. I changed it to "twrp.img".
I know I don't have to boot a live TWRP session from an image when it is already installed. However, whenever I try to use the TWRP I already installed, I cannot press anything becaue the touchsceen doesn't work. When I boot from live, that touchscreen works. It would be good to know how to fix the touchscreen on the installed version, but I'm willing to make do with booting from live if that is possible.
When I use "fastboot boot twrp.img" after renaming the file (it gave me a "no such file or directory" error before renaming the file), I still have the problem where it loads for a few seconds, then my device does black and disconnects from my computer, then soon goes bright and reconnects to my computer. This is what this looks like in the command line:
fastboot boot twrp.img
Sending 'boot.img' (98304 KB) FAILED (Status read failed (No such device))
fastboot: error: Command failed
Now it is not as though my device was never connected. I can use "fastboot devices" to verify it is connected when the screen isn't black. Also, the output looks different when my phone isn't connected at all:
fastboot boot twrp.img
< waiting for any device >
In one instace, the phone is connected and then disconnects. In the other instance, it is never connected.
My phone disconnects from and reconnects to my computer periodically. That is, roughly every 33-34 seonds. It reconnects quickly without my input (roughly every 4.5 seconds). I used a stopwatch to make sure of this.
Spoiler: Stopwatch Times
Connected (in seconds): 29.22, 34.11, 33.84, 34.03, 34.02, 33.75, 34.04, 34.05, 33.73, 33.93, 33.73
Disconnected: 4.28, 4.45, 4.50, 4.53, 4.51, 4.50, 4.48, 4.80, 4.50, 4.80, 4.60
I tested using "fastboot boot twrp.img" at the beginning of a connected interval. The command ran for the whole 33-34 seconds before the phone disconnected and it gave me that same error. I don't think that command took so long to execute when my phone wasn't turning black periodically. I can run other commands like "fastboot devices".
When my phone isn't connected to my computer, it doesn't turn black every 33-34 seconds.
Entering "adb reboot recovery" produces this error:
adb reboot recovery
error: no devices/emulators found
"adb devices" shows no devices attached. That has always been the case when running adb commands in the bootloader. I can run them when my phone is turned on normally (there is no OS so I can't do that now).
Thank you for your advice. Do you know anything about the phone disconnecting?

Try this, type:
fastboot devices
Then type:
fastboot reboot recovery
Or
If your device has a bootloader mode, try this, type:
fastboot devices
When it returns the serial number, type:
fastboot reboot bootloader
If you have a bootloader mode/menu, it should boot to that, then either select "reboot recovery" or type:
adb reboot recovery
Or
fastboot reboot recovery
ADB may or may not work in bootloader mode, if you have it.
Are you certain that your bootloader is unlocked and are you certain that you correctly flashed TWRP recovery to the correct partition and that the TWRP.img that you flashed onto the device is an actual TWRP recovery .img and not some kind of modified boot.img? I ask this because in your post above, you typed:
fastboot boot twrp.img
Then it returned
"sending "boot.img"(98304 KB) Failed"
This implies that you are using a boot.img, not a recovery.img/twrp.img. I think your file may be some kind of boot.img to be used in association with something to do with flashing/using TWRP or a boot.ing for your device that is meant to be flashed via TWRP(TWRP can flash .img files)
You can also try booting into your one-touch working TWRP, then, connect a USB hub to your android device and connect a mouse and keyboard, it should natively support the mouse and keyboard, you can use the mouse and keyboard to work inside TWRP to make selections.

Thank you. I tried doing "fastboot devices" then "fastboot reboot recovery" and "fastboot devices" worked and returned a serial number but "fastboot reboot recovery" kept running until the screen turned black and the phone disconnected from my computer. The same thing happened when I tried "fastboot devices" then "fastboot reboot bootloader".
I remember unlocking it by using I code I got from the phone to get another code I got from the Motorola website. It says "flashing_unlocked" on the screen when it hadn't before. I'm pretty sure I unlocked it unless it's supposed to say something else. I've seen another Motorola that just said "unlocked" but it wasn't the same exact device.
I am not certain I flashed TWRP to the correct partition.
I will try connecting a mouse and keyboard so I can use TWRP.
