Asus ZenPad C 7.0 Z170C - Real Bad Brick - No Bootloader - Android Q&A, Help & Troubleshooting

Hey Everyone,
So I have an Asus ZenPad C 7.0 Z170C and I was working on rooting the device. Long story short, I messed up and now I have a brick... or paper weight. I can at least use a paper weight for something....
Here is what my devices does currently:
When I try to boot the device, it gets stuck at the 2ND Asus screen and never actually boots up. I can get my device into fastboot (the GREEN background).
I can also get the device into RECOVERY mode by pressing (POWER + VOLUME DOWN) when booting the device.
However, I can only get the device to the screen with the DEAD ANDROID and "No Command" text screen. If I try getting the BOOTLOADER list to pop up, from the DEAD ANDROID screen, by pressing POWER + VOLUME UP, I get an error. The error is different depending on whether I have my EXTERNAL SD card in my device.
The error messages say the following:
EXTERNAL SD Card LEFT IN Device:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

Ive been searching and searching endlessly online all day and couldnt find anything that works. The closest I got was with the following:
Asus Flash Tool: Seems to work fine at first but then hangs. The "Unzip Image" step finishes and then it says "Rune Flash Image Script..." and does nothing. I let it run for over 1 hour and nothing changed.
Please let me know if there is anything else I can try. I do NOT care if my data is lost.
Thank you in advance!!

If you can get in the bootloader (POWER + VOLUME UP) and the device can be seen in the list on fastboot devices, then it should be easy to restore.

yes, I can do both.. whats your recommendation to restore?

Message "can't mount /sdcard" it means low quality SD card, take another and use the fat32.
Take the online ASUS update UL-P01Z-WW-12.26.4.45-user.zip and put the zip file on SD card.
After fastboot (POWER + VOLUME UP) do a hard reset:
Code:
fastboot format cache
fastboot format userdata
After that boot to recovery (POWER + VOLUME DOWN) and choose apply update from sd card.
It is not necessary to use the SD card. You can select in the menu apply update from ADB and specify the path to the file on your computer through ADB:
Code:
adb sideload "C:\adb\[B]UL-P01Z-WW-12.26.4.45-user.zip[/B]"
If the recovery menu does not appear, press any button once.
If you have a problem with recovery partition, do a hard reset (fastboot format ...), and then flash attached files (it is important to observe the sequence):
Code:
fastboot flash vrl "C:\adb\extracted_UL-P01Z-WW-12.26.4.45-user\vrl.bin"
fastboot flash recovery "C:\adb\extracted_UL-P01Z-WW-12.26.4.45-user\recovery.bin"
If errors appear on the command line, you may need to unlock the bootloader:
Code:
fastboot oem unlock
fastboot oem unlock confirm
or:
Code:
fastboot oem asus-go
fastboot oem asus-go confirm
The files vrl.bin and recovery.bin were obtained using the following instructions: https://forum.xda-developers.com/an...uimage-bin-t3191929/post72093244#post72093244

So I FINALLY got around to trying your steps and.... IT WORKED!!
Can't thank you enough. I decided to "Apply Update using ADB" instead of the SD card and your step by step guide was perfect.
Thanks Again!!!!

Can you post the system.img file for the Zenpad C 7..0 and maybe the other factory images too? I accidentally overwrote it and have no way to recover it since I forgot to back up the ROM.
