i have a mxq android tv box that is rooted. i flashed a custom rom on it and it worked perfectly. i then wanted to flash another custom rom onto it but it wouldnt go into recovery mode. i tried the toothpick method, as well as with boot apps. i tried flashing the rom using apps like rom manager, and flashify but they didnt work. whenever i try to enter recovery mode it restarts and boots up normally. after a few hours i tried to turn it on and now its stuck on the bootanimation. i tried plugging it into my computer but it wouldnt recognise it. any help would be appreciated

X-post from General,[Q] Help i think i bricked my system

So i got a new T F 300T yesterday and wanted to root it today.
I unlocked it and rooted it successfully. But then I tried installing a recovery. Installed CWM using fastboot. tried booting into it using RCK. It says booting into recovery mode and just reboots to OS. Installed CMW touch, same problem. Installed TRWP since i read that cmw has some problems.Now i used the 1 click root 1.1 to boot into recovery mode. The device now keeps rebooting. IT starts on the asus screen, then reboots again. So im stuck in a boot loop. When I press vlm dwn +power, it doesnt give me a menu anymore , instead it says that its rebooting into recovery mode and reboots again. Im freaking out right now, anyway to recover my device? Or is it 400 bucks down the dran? I dunno why this happened , since i am not new to flashing ROMs and stuff, and ususally test out new ROMs using my GNex. Any help would be appreciated, thanks.

Helping Hand please !

Im stuck on nvidia logo. With no recovery and OS.
I am planning to go back to stock.
But i cannot connect shield to my laptop. It doesn't connect, it just charging. I tried adb, i tried my device manager but i still got nothing.
Please, if anyone knows a solution on how to connect. Or to go back to stock
How do you know there's no recovery? Did you mess up the partition?
That part, i mean i used fastboot and success, but im stuck. Like its not installed. But when i tried twrp 3.1 it was installed but the problem is it wont touch.
If you can access fastboot, that means you can pretty much re-flash recovery and the ROM. Download the latest recovery image file from the Nvidia download center (it's 5.1). Don't need twrp for that

Phone shows a blank screen

Hello
Having some issues with my phone
I was using a custom rom beforehand and decided to flash the official stock rom because of a mobile app game that wouldn't boot on the phone. Doing that got rid of twrp and opened the stock recovery. Whenever I tried to reboot the phone it would keep taking me to the stock recovery. From there I decided to do a wipe but it continued to take me to the stock recovery. Not sure what to do I fast booted a .img file I used for the previous custom rom I was using and that booted the phone to a point where it had official stock and was rooted but the game still didn't work. So when I rebooted into recovery mode the twrp recovery appeared but when I checked my files everything was gone. Whenever I tried to reboot the phone it would just continue to take me into twrp recovery. Also I couldn't move files while it was in twrp. So I decided to format everything and that fixed my issue of booting. Now the phone booted as normal even tho I had to go through the intro again. I downloaded the game and huzzah it worked just fine. I booted into recovery mode to make sure it would boot fine from recovery to the phone and it did, but whenever I told twrp to reboot it would say there is no os installed but it would boot fine. Next I decided to get magisk back and running. So I got the manager and download the .zip and booted twrp and flashed it. When I rebooted my phone I just get a blank screen. Nothing happens when I press anything and pressing power + vol up restarts the phone but it goes back into a blank screen.
Help?

I've tried this but it doesn't work. Whenever I boot the program nothing shows up. I checked my ports and I have Qualcomm HS-USB QDLoader 9008 (COM8) which doesn't match the guide and I have no idea how to change the port.

The COM number actually doesn't matter, it will vary from pc to pc so yes it will work, nothing will show up on the phone screen its self, once u see HS-USB QDLoader 9008 open the msm tool and u will see it connect and start.
What custom ROM?
What game?
Which TWRP?
Which boot.img?
What firmware?
What everything?
How on earth can you expect anyone to help you when you decide to cloak your whole setup in mystery?
I fixed the issue. I didn't know about the button combo to boot into fastboot so when I did boot into fastboot I fastbooted into twrp and fixed everything from there

Need help flashing Katkiss 6.0.1 , Recovery Partition Not Found / Nothings Working

So, I just decided to try and Flash the old TF101 with Katkiss 6.0.1 and Gapps, but I always get stuck on the same problem.
My TF101 is running Android 4.0.3 ICS and USB Debugging is on
I downloaded TWRP app on the transformer, as well as the latest .blob flash file through the app.
Before this, I rooted the tablet using Kingroot.apk, which worked. When I went to flash the tablet with the recovery, the app noted "Recovery Partition not found".
I tried to boot into recovery mode on my own, (Pressing Pwr + Volume down , Then hitting Volume Up), The android screen popped, up and then flashed to a fallen android with a red triangle.... The screen stays on this for a minute and then boots into the normal system. I can't even boot into recovery through ADB, using the
Code:
adb reboot recovery
, The tablet will just reboot normally, not into recovery mode.
The Device does recognize through ADB....
Is my recovery partition just non existent? Even when I just let the system though without pressing volume up, it only gives me the option of (Android) or (Erase Data). when I click erase data, ill stay on the asus loading screen indefinitely and nothing will happen until i turn it off and on.
I just cant seem to boot into TWRP for some reason, and that means I just cant install the downloaded custom ROM.
How Can I fix this and boot into TWRP? I've tried for hours and have been hung up due to the same problem each time, even after rooting.
Did you already solve that problem? I also need a solution.Thanks

Samsung J400F stuck in loop after flashing custom recovery TWRP

Hello people!
I have a J400F phone model, I was working with android 9 rooted & working well, I updated to android 10 with a fresh install, the phone works well, and I wanted to use a custom recovery TWRP and root the phone, it stuck in boot loop, this is how I flashed:
- Used Odin with the latest stock firmware "J400FXXU6CTGO".
- restart the phone, and the bootloader is already unlocked "OEM Unlocked".
- Downloaded TWRP for J400F from halabtech, flashed it, then rebooted to recovery.
- In home screen, Wipe --> Format.
- With TWRP I flashed RMM_Bypass_v3_corsicanu.zip then no-verity-opt-encrypt-6.1.zip
After this I tried booting to system but then It kept rebooting after reaching the samsung logo.
Any help is appreciated guys.
I managed to access the download mode by taking out the battery, put it back in the phone, connect it to USB in the computer, press vol down and home button and you should be able to enter the download mode to flash the stock ROM (still reading on the second part).
