Mi pad 4 stuck in black screen after installing rom - Xiaomi Mi Pad 4 Questions & Answers

Hello,
After installing a xiaomi.eu rom via twrp, I cleared the cache, rebooted the system and then the screen went black and it is stuck in there. Any suggestions on how to resolve this issue? Thanks.
EDIT: Using fastboot, I was trying to reinstall twrp but i got the following message: FAILED (remote: Failed to load/authenticate boot image: 00000050)

[Q] E: Unable to mount '/system': Bricked after ROM Update

I tried to update my device with the newest ROM (Dirty Unicorns) and somehow bricked it. ...
The device just stuck in the flashing process for over 10 hours. After TWRP and Fastboot were still working, I tried a lot of things to revive the system, but everything I tried went wrong.
First I tried to flash the factory image. The strange thing: that seamed to work well (with Wugfresh toolkit), but the device still stuck in a bootloop.
Everything I try in the recovery mode ends by TWRP with "E: Unable to mount '/system'" (in red letters). So I tried to flash the factory image again and wiped the device in the newly flashed Revovery completely.
No change: "Updating partition details... E: Unable to mount '/system'".
- ABD sideload doesn't work. I tried to flash system.img. No success.
- Bootloader is unlocked. V3.44.1.0123
- Newest TWRP (twrp-2.8.7.0-flounder.img)
Here are the best Android-experts worldwide! So can someone please help me?
Thanks in advance!!
Regards,
Frank

Can't boot TWRP or CM14 recovery

Hi all,
I have a brand new OPX imported from China. I tried installing TWRP 3.0.2.0 through fastboot, and apparently the installation went fine. Except that when I try to boot on recovery, I'm stuck on the OP splash screen and nothing happens.
I tried with CM14 recovery, and I get the exact same issue.
So I installed CM13 recovery (latest version), and then CM13, and everything is working fine. But I can't update to CM14 (CMrecovery just tells me "install failed", and the recovery log shows one apparently relevant line, which is "[ 1.282239] failed to stat /data/media/0/cmupdater/cm-14.1-20161221-NIGHTLY-onyx.zip: No such file or directory").
I also tried installin the latest CM14 through CM13 recovery, but I get the same problem I got with TWRP: stuck on splash screen, nothing happens.
Don't know if relevant, but as I'm stuck on splash screens, the phone does not respond to ADB but it does respond to fastboot.
I would really like to install the latest CM14 on it, but for the moment I'm stuck with CM13. Any ideas?
Thanks!

Can you please describe which build date of cm 13 you are using right now?
I am using the latest CM13 available for my device (onyx), which is CM-13.0-20161219-NIGHTLY-onyx.
The next CM for this device is a CM14.

if you unlock your bootloader then definitely latest twrp 3.0.3 works fine and flash cm14 and arsenic kernal using it.
first you install the rom using twrp 3.0.3, then install arsenic kernal, after that flash gapps. This works fine for me. Maybe you can`t unlock your bootloader check using : fastboot oem device-info in the fastboot mode. Or you are using older bootloader. See this
http://forum.xda-developers.com/oneplus-x/general/guide-update-bootloader-firmware-to-t3478917
Arsenic kernel:http://forum.xda-developers.com/oneplus-x/development/kernel-arsenic-kernel-r2-t3422020
This is what 'fastboot oem device-info' tells me:
Code:
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: true
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) console_enabled: 0
(bootloader) exec_console_unconsole: 0
OKAY [ 0.006s]
finished. total time: 0.006s
And I still can't install any TWRP. I mean fastboot will tell me the install is successful, but trying to boot TWRP (or CM14 recovery) gets stuck on Android [1+] logo.

Bricked oneplus3

Basically I was an ***** and flashed a oneplus3t rom onto a oneplus3, I thought it was a oneplus3t as I have 2 and used the wrong one (DumbDumb).
I have downloaded the MSM tool and got it to boot now, however upon boot it is looping with several things failing.
Boot failed (Red text)
Boot_aging failed (Red text)
Cache Failed (Red text)
System Failed (Red text)
Recovery Failed (Red text)
MD5 Checksum Failed. (Red text)
I am able to get it into fast boot but that's it, no recovery, just fast boot or bootloop with errors shown above.
I have managed to fix the Cache fail by flashing the .img in adb cmd
Tried to flash all the others but not having any luck.
I had 8.1 nitrogen which is oreo based rom installed.
Anyone have any suggestions, I've been trying to fix it all day yesterday but no joy.
Hope someone can help.
I'm recieving the following error upon boot.
boot Failed
boot _aging Failed
recovery Failed
md5 checksum Failed
System said failed and Cache, I have flashed them in ADB alongside all the other ones, but they are still showing as failed.
Any help? I had nitrogen 8.1 installed, if I can find the .img files maybe I can flash them but I dont know, I tried flashing the files from all in one tool, only cache and recovery are fixed, the rest are still red.
