First you need to provide more info (i.e. did you tried to flash something before this issue occured?, your device is unlocked?) and maybe we can help you.

I can't read the error from that video but i think you should flash a boot.img via fastboot and then flash CWM or TWRP recovery the same vai (via fastboot). BTW you have to use a boot.img from a JB rom.

Error is 0x000000000
Where i can get boot.img?
Then i extract blob file, i get 5 blob filesblob.
HEADER – Header stuff (ignore it)
blob.APP – system.img
blob.LNX – boot.img
blob.SOS – recovery.img (e.g. regular boot.img)
blob.EBT – bootloader.bin (ignore)
Do i have to rename blob.LNX to boot.img or i should't ?
Do i need to erase all system boot recovery data?
Thanks.

You made the same mistake I made:

APX means you get to use nvflash, right?
I wish I was on the same boat.

Yes i can use nvflash.
but i can't restore my bootloder
maybe you know what to flash?

What do you mean with "Yes i can use nvflash"? You already used the NvFlash tool and have the backup files or is just the fact that you are able to boot in APX mode?
As for the other question, yes rename the blob files ( blob.LNX - > boot.img) and flash from fastboot (fastboot -i 0x0B05 flash boot boot.img). Make sure your battery is full, just in case.
Try to flash the recovery.img, boot.img and system.img using the abive method.

Just the fact
Flashed recovery boot system didn't helped
maybe someone knows how to flash with nvflash?

Being able to boot in APX doesn't mean you can use NvFlash to flash your device.If you never used the NvFlash tool to backup your files (and gain NvFlash access) you won't be able to do it anymore because a 9.4.5.26 or lower bootloader it's needed.
I'm not sure if the follow procedure will work but you could try to flash the complete blob via fastboot (rename the original asus blob to something like " tf700t.blob " , something like this : fastboot -i 0x0B05 flash staging tf700t.blob
Someone please correct me if the " flashing to staging" procedure is different.

ATM there's no way to do that ,Asus locked the bootloader pretty tight this time.
If you still can't manage to fix your issue i would recommend you an RMA ticket from Asus.

How to get the original ROM back?

Well I need to send in the Chacha because of some Hardware issues, so I'd like to restore the original ROM.
What's the easiest way getting it back (maybe with the option not having to root it again afterwards, or restoring the Clockwork-Backup)?

The best way is to download RUU, extract from it rom.zip and from that zip extract system.img, boot.img and recovery.img. Then flash those three via fastboot using these commands:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
And reboot your phone and you will have stock rom with stock recovery on it. Then you can use OTA update if available.

[Q] Installing stock Rom

Hello, i have this rom xeogenesis DEODEX rom. I want to install stock rom. I am on 4.2.1 bootloader, and i want to install Stock 4.2.1 rom
How to do that???

There are a couple of ways to do this. As you said your running CROMi-X DEODEX, 4.2 bootloader (twrp 2.4.4.0-4.2 or 2.5.0.0-4.2) - so example below to flash latest stock asus JB 4.2 firmware for tf300t model - TF300T-WW_epad-10_6_1_15_3-UpdateLauncher.zip.
Method 1: - Using TWRP
Download the asus firmware zip - TF300T-WW_epad-10_6_1_15_3-UpdateLauncher.zip
Unzip this to a folder and inside you will find another zip called WW_epad-user-10.6.1.15.3.zip - Copy this zip file to your microSD.
Insert microSD in tab and reboot to twrp recovery, flash the WW_epad-user-10.6.1.15.3.zip , reboot, Done :good: You will now be on stock asus firmware, stock recovery & stock kernel.
Method 2 - Using fastboot - Assuming here android-sdk is installed and fastboot & adb working.
Download the asus firmware zip - TF300T-WW_epad-10_6_1_15_3-UpdateLauncher.zip
Unzip this to a folder and inside you will find another zip called WW_epad-user-10.6.1.15.3.zip
Here I put a copy of the WW_epad-user-10.6.1.15.3.zip on my micro SD card
On PC unzip WW_epad-user-10.6.1.15.3.zip and you will find a "blob" file- this is the system blob file for that firmware which is the system, stock recovery, kernel & bootloader all rolled into a one blob file.
Copy this blob file to your android-sdk/platform-tools folder
The version of TWRP you need for the JB 4.2 - 10.6.1.15.3 bootloader is "openrecovery-twrp-2.5.0.0-tf300t-4.2.blob" - flashing a non-4.2 version of TWRP or any version of CWM will brick device. Not sure if 2.4.4.0-tf300t-4.2 works on 10.6.1.15.3 bootloader.
So download "openrecovery-twrp-2.5.0.0-tf300t-4.2.blob" and also put this in android-sdk/platform-tools folder - you can rename it to something shorter if you want, say twrp-2.5.0.0-4.2.blob
Now connect tab to pc and boot to fastboot and check that pc can see your device ok
Code:
fastboot devices
should see device s/n here, if ok we can flash the system blob we put in the platform-tools folder
Code:
fastboot -i 0x0b05 flash system blob
This will take 10ish minutes, it will send file then write file and you should a blue progress bar on tab when it starts to write.
When complete
Code:
fastboot reboot-bootloader
You should now check & confirm that your bootloader has upgraded, look at the text in the top left of the bootloader screen and make sure it now has 10.6.1.15.3 in the text.
Here you should really be able to just reboot the tab and be fine but I would get stuck at boot animation so next part is a second flash of the same firmware but via TWRP recovery instead of fastboot, so method 1 - but you now have stock recovery so we need to flash TWRP first.
So in fastboot flash the "openrecovery-twrp-2.5.0.0-tf300t-4.2.blob" I shortened to "twrp-2.5.0.0-4.2.blob"
Code:
fastboot -i 0x0b05 flash recovery twrp-2.5.0.0-4.2.blob
again here you should see a blue progress bar on your tab
When done reboot to bootloader again
Code:
fastboot reboot-bootloader
This time select the RSK icon and boot TWRP recovery. In recovery I do a full wipe then follow method 1 and flash the WW_epad-user-10.6.1.15.3.zip from microSD, reboot & done :good: - You will now be on stock asus firmware, stock recovery & stock kernel.
If you need any more help just ask or have a look at my how-to in sig below for more info.

Thanks for that looong post . I did that but I forgot to do a wipe after installing... I was very upset. But I did wipe and now my tablet fully workin'. THANKS!!!

[A510] I need stock system.img

I need stock system.img in order to flash it via fastboot. I have deleted my recovery and now i have no rom installed so i need these files. Hope someone can uploaded them fast because i am running out of time.

As said by PM
Reboot in fastboot, and do
fastboot boot recovery.img
(using CWM or TWRP)
In recovery, you will be able to flash a ROM or restore a backup.

[Q] Update stock even if rooted

The only things that will wipe your data:
unlocking the bootloader (which I assume you already have unlocked due to having root access)
flashing userdata.img (if you read my previous post, I left this out)
wiping the data partition in recovery
factory reset option in Android (which really just boots into recovery and wipes data from there)
