Nvidia Shield Tablet bootloop, twrp recovery not working (stuck on nvidia logo) - Shield Tablet Q&A, Help & Troubleshooting

Device has been rooted ever since I got it, was running with cyanogen mod. Yesterday I flashed CM13 but it got stuck in a bootloop afterwards. Then I tried to flash a newer version of TWRP and now nothing is working at all. As soon I go to recovery mode, the tablet gets stuck on the nvidia logo (no "no command screen showing up either, even after over 45 mins). Same if I start it up normally. Anyone able to help?

[Q] Constant Bootloop Wingray

Yesterday I attempted to update my Xoom to the newest EOS nightly. After installing/wiping/rebooting I found myself with the RSD mode 3 problem. Having encountered this before I used ADB to flash a stock boot & CWM recovery. After this I have tried to flash several different roms (EOS 3/ EOS 4 nightly/CyanogenMod nightly) but each time the device gets stuck at the boot logo, not the motorola dual core screen but the actual ROM boot logo. Any ideas what I should do/try next? I'm sure there must be a simple solution to this, I just don't know/can't find it

stuck in boot logo

Hi everybody, my name is davide and im from italy...

something has gone wrong... the phone is stuck on the boot logo (powered by android)

itself in the same boot logo. my friend told me that the phone was original (he didn't install
custom recovery or unlock bootloader).

Alcatel Pixi 4 (6) 8050D 2017 Edition - Stuck In Boot Loop No Recovery

So i got this phoen the other day and noticed the pre installed rom is taking up to many resources, so i decided to try and root the phone and install a custom rom, after the phone rebooted from using Kingo Root It got stuck in an infinite boot loop.
Phone just restarts over and over again, i help Power and Volume Up, this takes me to the boot loader screen and i selected recovery, now i jhad twrp installed and naturally assumed that it would go into recovery mode, Well it didnt and now i am stuck with a phone that just either restarts or sits in fastboot mode when i put it into it.
Any suggestions, to be honest i cant find any stock rom for it, this is the only phone i have and i need it.
Go to the official website and download upgrade tool .. it will identify the phone then downloads the firmware and u get ur stock ROM
